Step-by-step explanation:

Last year's score = 350

This year's score = 399

What was the percent of increase in Kenia's score

Percentage increase= (new score - old score) / old score × 100

= (399-350) / 350 × 100

= 49 / 350 × 100

= 0.14 × 100

= 14%

The percent of increase in Kenia's score is 14%

Answer:

10/9 is the answer.

Step-by-step explanation:

The probability that there are an equal number of heads and tails and the first three flips are heads, given six total flips, is 1/64.

To calculate the probability that there are an equal number of heads and tails and the first three flips are heads, we need to consider the number of possible outcomes and the number of favorable outcomes.

In this case, we have a sequence of coin flips, and we want an equal number of heads and tails. For an equal number of heads and tails, we need an even total number of flips.

Let's consider the possible number of total flips:

If we have 2 flips, the sequence can be "HH" or "TT," but we need the first three flips to be heads. Therefore, 2 flips is not a favorable outcome.

If we have 4 flips, the possible sequences are "HHHH" or "HHTT" or "TTHH" or "TTTT." Out of these sequences, only "HHHH" satisfies the condition of having the first three flips as heads. Therefore, 4 flips is a favorable outcome.

If we have 6 flips, the possequences sible are "HHHHHH," "HHHHTT," "HHTTHH," "HHTTTT," "TTTTTT," "TTTTHH," "TTTTHH," and "TTTTTT." Among these sequences, only "HHHHHH" satisfies the condition of having the first three flips as heads. Therefore, 6 flips is a favorable outcome.

From this pattern, we can see that for an even number of total flips, there will always be one favorable outcome where the first three flips are heads.

Now let's consider the total number of possible outcomes:

For each flip, there are two possible outcomes, either a head or a tail. Therefore, for N flips, the total number of possible outcomes is 2^N.

So, for an even number of total flips, the probability of having an equal number of heads and tails and the first three flips being heads is:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

= 1 / 2^N

In this case, since we have 6 flips (N = 6), the probability is:

Probability = 1 / 2^6

= 1 / 64

Therefore, the probability is 1/64.

Step-by-step explanation:

The measure of the smallest angle between the beams and the roof is 35⁰.

The measure of the smallest angle between the beams and the roof is calculated by determining the value of x.

The value of x is calculated as follows;

3x + 10 + 90 + 2x + 5 = 180

5x + 105 = 180

5x = 75

x = 75/5

x = 15

The measure of the angles is calculated as follows;

3x + 10

= 3 x 15 + 10

The solution of the DTDS is xn = (0.63)^n * 41 grams, where n represents time in hours.

a) The updating function f(x) for the discrete time dynamical system (DTDS) can be derived from the given information that the body eliminates 37% of the alcohol present in the body per hour.

Since 37% of the alcohol is eliminated, the amount remaining after one hour can be calculated by subtracting 37% of the current amount from the current amount. This can be expressed as:

f(x) = x - 0.37x

Simplifying the equation:

f(x) = 0.63x

b) The initial condition for the DTDS is given as Peter having 41 grams of alcohol in his body after consuming three alcoholic drinks. Therefore, the initial condition is:

x0 = 41 grams

c) To find the solution of the DTDS with the given initial condition, we can use the updating function f(x) and iterate it over time.

For n hours, the solution is given by:

xn = f^n(x0)

Applying the updating function f(x) repeatedly for n times:

xn = f(f(f(...f(x0))))

In this case, since the function f(x) is f(x) = 0.63x, the solution can be written as:

xn = (0.63)^n * x0

Substituting the initial condition x0 = 41 grams, the solution becomes:

xn = (0.63)^n * 41 grams

The general solution to the given differential equation is:

y = C1 + C2e^x + C3e^(-x) + C4x, where C1, C2, C3, and C4 are constants determined by initial or boundary conditions.

To find the general solution of the given differential equation, we'll first find the particular solution (yp) using the method of undetermined coefficients, and then we'll find the complementary solution (yc) by solving the associated homogeneous equation. Finally, we'll combine the particular and complementary solutions to obtain the general solution.

The given differential equation is: y(4) - y" = 5e + 3

Step 1: Find the particular solution (yp):

To find the particular solution (yp), we assume it has the form yp = Ae + Be^3, where A and B are constants to be determined.

Taking the first and second derivatives of yp:

yp' = A + 3Be^3

yp'' = 9Be^3

Substituting yp, yp', and yp'' into the differential equation:

9Be^3 - 9Be^3 = 5e + 3

The exponential terms cancel out, leaving us with:

0 = 5e + 3

Since there is no solution for this equation, we conclude that the particular solution is not possible. We'll need to approach this problem using an alternative method.

Step 2: Find the complementary solution (yc):

To find the complementary solution (yc), we'll solve the associated homogeneous equation:

y(4) - y" = 0

The characteristic equation is: r^4 - r^2 = 0

Factoring out r^2, we have:

r^2(r^2 - 1) = 0

This equation gives us two sets of roots:

r1 = 0, r2 = 1, r3 = -1, r4 = 0

The general solution of the associated homogeneous equation is:

yc = C1 + C2e^x + C3e^(-x) + C4x

Step 3: Find the general solution:

The general solution is obtained by combining the particular and complementary solutions:

y = yp + yc

Since we couldn't find a particular solution (yp), the general solution becomes:

y = yc = C1 + C2e^x + C3e^(-x) + C4x

Answer: Pigs = 21

Chicken = 45

Step-by-step explanation:

Let the pigs be represented by p

Let the chicken be represented by c.

From the question,

p + c = 66

4p + 2c = 174

4 × ( p + c = 66)

1 × (4p + 2c = 174)

4p + 4c = 264

- 4p + 2c = 174

2c = 90

c = 90/2 = 45

There are 45 chickens

Simce the farmer has a total of 66 animals, the number of pigs will be:

Given that figure GOALR is equilateral and equiangular:That is, GO = OA = AL = GLGOALR is an equilateral triangle (since all its sides are equal).So, ∠O = ∠A = ∠L = ∠G = 60°OA || GL and OA ≅ GLSo, ∠OAL = ∠GLA = 60° ............ (i)Also, OA || GL and ∠OAL and ∠GLA are alternate interior angles, hence they are congruent.So, OL is the transversal.∠YGL and ∠YAL are corresponding angles, hence they are congruent.Also, ∠L is common to ∠YGL and ∠YAL.So, by angle-angle criterion of similarity, ΔYAL is similar to ΔYGL.Accordingly, we can deduce that:∠YGA = ∠YAL (corresponding angles of similar triangles) ∠ALY = ∠GLY (corresponding angles of similar triangles)Now, ∠YGA = ∠G = 60° ............ (ii)In ΔYAL, ∠YAL = ∠ALY (as per (i))Also, ∠YAL + ∠ALY + ∠YLA = 180° (since YLA is a triangle)Now, ∠YAL = ∠ALY = x (let's assume this)So, ∠YLA = 180° - 2x ............ (iii)From (ii), ∠G = 60°So, ∠GLY = ∠G + ∠YGL = 60° + x ............ (iv)From (i), ∠OAL = ∠GLA = 60°So, ∠YAL = ∠OAL - ∠OAY = 60° - x ............ (v)From (iii), (iv) and (v):∠YLA = 180° - 2x = ∠YAL + ∠ALY = (60° - x) + (60° + x) = 120°So, in ΔYLA, we have ∠YLA = ∠ALY (as ∠ALY = x = 60° - ∠YAL/2 = 60° - ∠YLA/2)So, ΔYLA is an isosceles triangle (since it has two equal angles).Therefore, YLA is an Isosceles triangle.

To determine the fraction of their journey that they drove, we need more information about the specific distances covered by each mode of transportation.

In order to calculate the fraction of their journey that the Robinson family drove, we need to know the distances covered by each mode of transportation. Let's assume that the distances covered by air and train are given as fractions or percentages of the total journey.

For example, if they traveled by air for 1/4 of the journey and by train for 2/5 of the journey, we can calculate the fraction of the journey they drove by subtracting the sum of the fractions covered by air and train from 1. In this case, the fraction they drove would be 1 - (1/4 + 2/5) = 1 - (5/20 + 8/20) = 1 - (13/20) = 7/20.

The minimum number of people your wife could have shaken hands with is 10. This means she shook hands with everyone except herself.

Let's analyze the given information step by step to determine the number of people your wife shook hands with:

You invited 10 couples to the party, which means there are 20 people present, excluding yourself.

Since you didn't question yourself, we are left with 19 people to consider.

Each person you questioned shook hands with a different number of people.

Assuming no one shook hands with their partner, we can infer that each person shook hands with a number of people ranging from 0 to 18 (excluding themselves and their partner).

Now, let's consider the possibilities:

If someone shook hands with 18 people, it would mean they shook hands with everyone else except themselves and their partner. However, this is not possible because it contradicts the statement that everyone shook hands with a different number of people.

If someone shook hands with 17 people, it means they didn't shake hands with only two people out of the remaining 18. However, this is also not possible because it would imply that two people shook hands with the same number of people.

Continuing this pattern, we can conclude that no one can shake hands with 16, 15, 14, or any number up to 9 people because it would result in someone shaking hands with the same number as someone else.

Therefore, the minimum number of people your wife could have shaken hands with is 10. This means she shook hands with everyone except herself.

In conclusion, your wife shook hands with 10 people at the party, excluding herself and you.

The required solution for the hypothesis testing is shown.

Statistics is the study of mathematics that deals with relations between comprehensive data.

Here,
Part A:

The null hypothesis (H0) is that the company's claim is true, and the proportion of defective batteries is 5% or less.

The alternative hypothesis (Ha) is that the company's claim is false, and the proportion of defective batteries is greater than 5%.

H0: p ≤ 0.05

Ha: p > 0.05

where p represents the proportion of defective batteries.

Part B:

A Type I error in this context would be rejecting the null hypothesis (i.e., finding significant evidence that the proportion of defective batteries is greater than 5%) when it is actually true (i.e., the proportion of defective batteries is 5% or less). This would be a false positive result.

A Type II error would be failing to reject the null hypothesis (i.e., not finding significant evidence that the proportion of defective batteries is greater than 5%) when it is actually false (i.e., the proportion of defective batteries is greater than 5%). This would be a false negative result.

Part C:

If the hypothesis is tested at a 5% level of significance instead of 1%, this means that the criteria for rejecting the null hypothesis will be less stringent. In other words, it will be easier to find significant evidence that the company's claim is false. Therefore, increasing the level of significance from 1% to 5% will increase the power of the test.

Part D:

If the hypothesis is tested based on the sampling of 500 boxes of batteries rather than 100 boxes of batteries, this means that the sample size is larger. As a result, the standard error of the estimate will be smaller, and the test will be more precise. This increased precision will increase the power of the test.

Solution

- The solution steps are given below:

The total distance traveled by the particle over the time interval 0 ≤ t ≤ 3 is approximately 3.95 units.(a) The acceleration of a particle is the derivative of its velocity function. Given the velocity function v(t) = 1 + e^(-t), we find the acceleration by differentiating with respect to time:

a(t) = dv(t)/dt = -e^(-t)

At t = 3, the acceleration is a(3) = -e^(-3) ≈ -0.05.

(b) To determine if the speed of the particle is increasing at t = 3, we need to examine the relationship between the velocity and acceleration at that time. If their signs are the same, the speed is increasing. At t = 3, v(3) = 1 + e^(-3) ≈ 1.05 (positive) and a(3) ≈ -0.05 (negative). Since the signs are different, the speed is not increasing at t = 3.

(c) A particle changes direction when its velocity changes sign. To find the values of t when this occurs, we must solve the equation v(t) = 1 + e^(-t) = 0 for t. Rearranging, we get e^(-t) = -1, which has no real solutions since e^(-t) is always positive. Therefore, the particle never changes direction.

(d) To find the total distance traveled over the interval 0 ≤ t ≤ 3, we must integrate the speed function, which is the absolute value of the velocity function: |v(t)| = |1 + e^(-t)|. Since the particle never changes direction, the absolute value is unnecessary:

Distance = ∫(1 + e^(-t)) dt from 0 to 3

Evaluating this integral, we get [t - e^(-t)] from 0 to 3. Plugging in the limits, we obtain:

Distance = (3 - e^(-3)) - (0 - e^(0)) = 3 - e^(-3) + 1 ≈ 3.95.

So, the total distance traveled by the particle over the time interval 0 ≤ t ≤ 3 is approximately 3.95 units.
