The equation representing the situation of the statement is (1.25x + 5)9 = 155, and Christina will have to walk a distance of 9.77 miles to raise $155.

Equation: A statement stating the equality of two expressions with variables or integers. Since equations are essential questions, attempts to systematically discover the answers to these questions have been the primary motivations for the development of mathematics.

Given:

Donations to start the race = $5

Donation per mile of race = $1.25

Total donor = 9

Total money to be earned = $155

Write the equation as shown below,

(1.25x + 5)9 = 155  (Here, x is the distance in miles)

1.25x + 5 = 17.22

1.25x = 12.22

Answer:

step-by-step explanation: 1cm is equal to 10mm

The volume of a cuboid is length ×breadth×height

We start by converting 60 mm into cm which will be 6cm

Solution :

Answer:

41%

Step-by-step explanation:

First, we have to find what percent is dirty, so our equation is:

118/200 = 59/100 = 59%

Then we have to find how much of 100% is left after we take away 59%:

100 - 59 = 41

So 41% of the plates are clean

To represent decimal values ranging from 0 to 12,500, we need 14 bits.

To determine the number of bits needed to represent decimal values ranging from 0 to 12,500, we need to find the smallest number of bits that can represent the largest value in this range, which is 12,500.

The binary representation of a decimal number requires log base 2 of the decimal number of bits. In this case, we can calculate log base 2 of 12,500 to find the minimum number of bits needed.

log2(12,500) ≈ 13.60

Since we can't have a fraction of a bit, we round up to the nearest whole number. Therefore, we need at least 14 bits to represent values ranging from 0 to 12,500.

Using 14 bits, we can represent decimal values from 0 to (2^14 - 1), which is 0 to 16,383. This range covers the values 0 to 12,500, fulfilling the requirement.

Step-by-step explanation:

The y-intercept of the line represented by the equation is; 60.

It follows from the task content that the y-intercept of the line represented by the equation is to be determined.

On this note, we must recall that the y-intercept of an equation is the value of y when x = 0.

Therefore, we have;

To solve the initial value problem y'' - 2y' - 3y = 0, with y(0) = 1 and y'(0) = 2, we can use the method of Laplace transforms.

First, we take the Laplace transform of the given differential equation to obtain an algebraic equation in terms of the Laplace transform of the unknown function y(t). Then, we solve the algebraic equation for the Laplace transform of y(t) using standard algebraic techniques. Finally, we take the inverse Laplace transform to obtain the solution y(t) in the time domain.

Applying the Laplace transform to the given differential equation, we have s²Y(s) - sy(0) - y'(0) - 2(sY(s) - y(0)) - 3Y(s) = 0, where Y(s) represents the Laplace transform of y(t). Simplifying this equation, we get (s² - 2s - 3)Y(s) - (s - 2) = s²Y(s) - 3s - 4. Rearranging the equation, we have Y(s) = (s - 2) / (s² - 2s - 3).

To solve this equation for Y(s), we can decompose the expression into partial fractions, which yields Y(s) = 1 / (s - 3) - 1 / (s + 1). Taking the inverse Laplace transform of Y(s), we obtain y(t) = e^(3t) - e^(-t), which is the solution to the initial value problem.

If a person is chosen at random, and they are a heavy drinker, the probability of that person having a liver ailment is 0.053.

A random sample of 1,000 people,

7.4% have a liver ailment.

P(Have liver ailment) = 0.074

P(Have no liver ailment) = 1 - P(Have liver ailment)

P(Have no liver ailment) = 1 - 0.074

P(Have no liver ailment) = 0.926

Those who have a liver ailment, 9% are heavy drinkers.

P(Have liver ailment | Heavy drinkers) = 0.09

Those who have a liver ailment, 60% are moderate drinkers.

P(Have liver ailment | moderate drinkers) = 0.60

Those who have a liver ailment, 31% are nondrinkers.

P(Have liver ailment | nondrinkers) = 0.31

Those who do not have a liver ailment, 13% are heavy drinkers,

P(Have no liver ailment | Heavy drinkers) = 0.13

Those who do not have a liver ailment, 48% are moderate drinkers.

P(Have no liver ailment | moderate drinkers) = 0.48

Those who do not have a liver ailment, 39% are nondrinkers.

P(Have no liver ailment | nondrinkers) = 0.39

If a person is chosen at random, and they are a heavy drinker, then we have to determine the probability of that person having a liver ailment.

P(heavy drinker) = P(have liver ailment) × P(Have liver ailment | Heavy drinkers) + P(have no liver ailment) × P(Have no liver ailment | Heavy drinkers)

P(heavy drinker) = 0.074 × 0.09 + 0.926 × 0.13

P(heavy drinker) = 0.00670.1204

P(heavy drinker) = 0.1271

P(Have liver ailment| heavy drinker) = P(Have liver ailment) × P(Have liver ailment | Heavy drinkers)/P(heavy drinker)

P(Have liver ailment| heavy drinker) = (0.074 × 0.09)/0.1271

P(Have liver ailment| heavy drinker) = 0.0067/0.1271

P(Have liver ailment| heavy drinker) =0.053

Answer:

48 inches

Step-by-step explanation:

Every foot is half an inch. So if there is 12 feet then that means there is 6 inches because 12x0.5= 6. 16x0.5= 8, which means 16 feet equals 8 inches. Now that we have the converted measurements we must find out the dimensions of the dollhouse living room. 6 inchx8 inch = 48 inches.

The statement is true. If we take any two distinct prime numbers, and the number "1", these numbers will always be pairwise relatively prime.

Two numbers are said to be pairwise relatively prime if their greatest common divisor (GCD) is equal to 1. In this case, since we are considering distinct prime numbers, their GCD will always be 1 since prime numbers have no common factors other than 1 and themselves. Therefore, any two distinct prime numbers will be relatively prime.

Similarly, when we consider the number "1", it is relatively prime to any other number because its only divisor is 1. Hence, when "1" is paired with any prime number, the GCD will be 1.

In summary, whether we consider two distinct prime numbers or pair them with the number "1", the resulting numbers will always be pairwise relatively prime.

Answer:

10

Step-by-step explanation:

data=11,7,21,14,9,x

mean=sum of data/no of data

12=11+7+21+14+9+x/6

12*6=62+x

72-62=x

10=x

therefore sixth number is 10.

The given problem is asking for a test to see if the sample mean is significantly different from 85 at the 0.05 level. To solve the problem, we can use the following formula:$$t = \frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}}}$$where$\bar{x}$ = sample mean$\mu$ = population mean$s$ = sample standard deviation$n

$ = sample sizeTo calculate the t-value, we need to calculate the sample mean and the sample standard deviation. The sample mean is calculated as follows:$$\bar{x} = \frac{\sum_{i=1}^{n} x_i}{n}$$where $x_i$ is the score of the $i$th student and $n$ is the sample size.

Using the given data, we get:$$\bar

{x} = \frac{78+89+67+85+90+83+81+79}{8}

= 81.125$$The sample standard deviation is calculated as follows:$$

s = \sqrt{\frac{\sum_{i=1}^{n} (x_i - \bar{x})^2}{n-1}}$$Using the given data, we get:$$

s = \sqrt{\frac{(78-81.125)^2+(89-81.125)^2+(67-81.125)^2+(85-81.125)^2+(90-81.125)^2+(83-81.125)^2+(81-81.125)^2+(79-81.125)^2}{8-1}}

= 7.791$$Now we can calculate the t-value as follows:$$

Answer:

The Answer for 19 is x+y=38.

The Answer for 20 is  2x+5y=100.

The correct solution are,

(C) a=1, b=2, c=3.

The code segment does not work in the case where a > b, c > b, but a < c.

In this case, the value of 'low' is set to 'b' instead of 'a', which causes the code segment to print the incorrect value.

The values of a, b, and c that fall into this case are a=1, b=2, and c=3.

Let's trace through the code segment using a=1, b=2, and c=3:

Since a=1 and b=2, the first conditional statement (a > b && b > c) evaluates to false, so we skip the first 'if' block.

Since a=1 and c=3, the second conditional statement (a > b && c > b) evaluates to true, so we set 'low' to 'b'.

However, since we have an 'else' block following the second conditional statement, it will always be executed. So, 'low' is set to 'a' instead.

Finally, the code segment prints the sum of a + b + c - low, which is 1+2+3-1 = 5, which is incorrect.

The correct answer should be 1 + 3 = 4.

Therefore, the answer is (C) a=1, b=2, c=3.
