Hi! I’m super confused on the second page but for the first page I only need help on #11. Could you please let me know if the problems I did answer on the first page are correct?

Answer:

B

Step-by-step explanation:

The probability at least 7 of the puppies will be male is approximately 0.0805 or 8.05%.

To determine the probability that at least 7 of the puppies will be male, we will have to use the binomial probability formula.

P(X ≥ k) = 1 - P(X < k)

where X is the number of male puppies, P is the probability of a puppy being male and k is the minimum number of male puppies required.

We can solve this problem by finding the probability that 0, 1, 2, 3, 4, 5, or 6 of the puppies are male, and then subtracting that probability from 1. We use the binomial distribution formula to find each of these individual probabilities.

P(X=k) = nCk * pk * (1-p)n-k

where n is the total number of puppies, p is the probability of a puppy being male (0.5), k is the number of male puppies, and nCk is the number of ways to choose k puppies out of n puppies. We'll use a calculator to compute each probability:

P(X < 7) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6)

P(X = 0) = 11C0 * 0.5⁰ * (1-0.5)¹¹ = 0.00048828125

P(X = 1) = 11C1 * 0.5¹ * (1-0.5)¹⁰ = 0.00537109375

P(X = 2) = 11C2 * 0.5² * (1-0.5)⁹ = 0.03295898438

P(X = 3) = 11C3 * 0.5³ * (1-0.5)⁸ = 0.1171875

P(X = 4) = 11C4 * 0.5⁴ * (1-0.5)⁷ = 0.24609375

P(X = 5) = 11C5 * 0.5⁵ * (1-0.5)⁶ = 0.35595703125

P(X = 6) = 11C6 * 0.5⁶ * (1-0.5)⁵ = 0.32421875

P(X < 7) = 0.00048828125 + 0.00537109375 + 0.03295898438 + 0.1171875 + 0.24609375 + 0.35595703125 + 0.32421875 = 1 - P(X < 7) = 1 - 1.08184814453 = -0.08184814453 ≈ 0.0805

Therefore, the probability that at least 7 of the puppies will be male is approximately 0.0805 or 8.05%.

like I said, find the square area and subtract the triangles.

28 x 28= 784

Find the dimensions of the triangles. Since the surrounding shape is a square, the legs should be equal in length.

28-11.6=16.4

16.4/2=8.2

8.2 is the leg's length.

8.2*8.2*1/2*4=134.48

Subtract it to the square's area. 784-134.48= 649.52

Assuming last night, the diner served 35 sodas in all, 28 of which were regular. The  percentage of the sodas  that were regular is: 55.6%.

First step is to  find the total

Total = Number of sodas + Regular

Let plug in the formula

Total = 35 + 28

Total = 63

Now let find the percentage of sodas that are regular

Percentage = Number of sodas / Total

Let plug in the formula

Percentage = 35/63 × 100

Percentage = 55.55%

Percentage = 55.6% (Approximately)

Answer:

-8

Step-by-step explanation:

ky^2 = -5y + 7y^2 +9y - 15y^2 -4y

ky^2 = -8 y^2

k = -8

Answer:

  8

Step-by-step explanation:

We believe the problem here requires that all of the coefficients in the expression on the left be zero. That is, the equation will be true for any value of y.

We can work this a couple of ways. One of them is to simplify the given expression. Let 'a' represent our unknown coefficient.

  \(-ay^2-[-5y-y(-7y-9)]-[-y(15y+4)]=0\\\\-ay^2-[-5y+7y^2+9y]+[15y^2+4y]=0\\\\-ay^2-[7y^2+4y]+15y^2+4y=0\\\\(-a-7+15)y^2+(-4+4)y=0\\\\(-a+8)y^2=0\)

In order for this to be zero for all values of y, we must have (-a+8) = 0.

  a = 8

The missing coefficient is 8.

_____

Since this expression must be true for every value of y, another way to work this is to choose a value of y. This will tell us what the coefficient must be for the expression to be zero. Let y = 1.

  -a·1² -[-5·1 -1(-7·1 -9)] -[-1(15·1 +4)] = 0

  -a -[-5-(-16)] -[-19] = 0

  -a -11 +19 = 0

  -a +8 = 0

  a = 8 . . . . . . same as above

_____

Additional comment

The many minus signs are intended to make sure you're comfortable with arithmetic with negative coefficients and negative numbers. The key, of course, is that -(-a) = +a. The opposite of the opposite is the original.

We have assumed that the dash at the beginning of the line (before the answer box) is intended to be a minus sign. If that is not the case, then your answer will be -8, instead of 8.

To determine the height the tree should be, we need to subtract the desired space between the ceiling and the tree from the total height of the room. The tree must be 280 centimeters tall to leave 50 centimeters of space between its top and the ceiling.

Given that the ceiling is 230 centimeters high and we want 50 centimeters of space between the tree and the ceiling, we can calculate the required height as follows:

Total height of the room = Ceiling height + Space between ceiling and tree

Total height of the room = 230 cm + 50 cm

Total height of the room = 280 cm

Therefore, the tree must be 280 centimeters tall to leave 50 centimeters of space between its top and the ceiling.

Step-by-step explanation:

Since the base angles are congruent then the triangle is isosceles with both legs being equal.

Using Pythagoras' identity in the right triangle

y² = 9² + 9² = 81 + 81 = 162 ( take the square root of both sides )

y = \(\sqrt{162}\) = \(\sqrt{81(2)}\) = 9\(\sqrt{2}\)

The rate of change of population of Green Bay was the greatest in the year 1990-2000.

A rate in mathematics is a ratio that contrasts two distinct values with dissimilar units.

John's typing speed, for instance, would be 50 words per minute if we assumed he typed 50 words per minute.

The prefix "per" indicates that we are discussing a rate.

The symbol "/" can be used in place of the word "per" in issues.

Let's use the case of an automobile that can travel 150 miles in 3 hours as an illustration.

You may calculate this by dividing 150 miles by three hours, which equals 150 miles/three hours or 50 miles per hour.

The word "per" in this context refers to each hour.

The average speed of the car is 50 miles per hour.

Change in population (in thousands) in 10 year period:

In, 1970-1980:

175-158 = 17

In, 1980-1990:

195-175 = 20

In 1990-2000:

227 - 195 = 32

32,000 is the largest growth in a 10 year period, so the answer is 1990-2000.

If triangle + triangle + triangle =circle + circle and triangle +circle =30, then there are 15 circles and 15 triangles.

Based on the facts provided, we can say:

triangle + triangle + triangle = circle + circle_______________(1)

triangle + circle = 30_________________(2)

Let's start with equation (2). We can see that the sum of a triangle and a circle is 30. Hence, we can write:

triangle + circle = 30

Now we can substitute this into equation (1), which gives:

triangle + triangle + triangle = (triangle + circle) + (circle)

⇒ 3(triangle) = 2(circle) + triangle

To solve for the number of triangles in terms of the number of circles, we can rearrange this equation as follows:

2(triangle) = 2(circle)

⇒ triangle = circle

As a result, we have discovered that the quantity of triangles and circles is identical. So that we can determine the value of each form, we can substitute this into equation (2) as follows:

triangle + circle = 30

⇒ 2(triangle) = 30

⇒ triangle = circle = 15

Hence, the solution is that there are 15 circles and 15 triangles.

The compound inequality that represents the number of ounces of clay, "c", Elisa uses to make one vase of either size is [(c ≤ 4.5) or (c ≥ 12)].

As per the question statement, Elisa uses no more than 4.5 ounces of clay to make a small vase and at least 12 ounces of clay to make a large vase.

We are required to find out the compound inequality that represents the number of ounces of clay, that she uses to make one vase of either size.

Let the number of ounces of clay, that Elisa uses to make one vase of either size be denoted by "c".

Since, Elisa uses no more than 4.5 ounces of clay to make a small vase, The words "no more than" implies maximum, i.e., "either less than or equals to" and hence, for a small vase, "c" must be less than or equal to 4.5 oz, which gives \((c \leq 4.5)\) ...(1)

On the other hand, to make a large vase, she uses at least 12 ounces of clay where the words "at least" means minimum, i.e, "either more than or equals to" and hence, for a large vase,

Thus "c" is more than or equal to 12 oz, which gives \((c \geq 12)\)...(2)

Now, combining (1) and (2), we get [(c ≤ 4.5) or (c ≥ 12)] which is option "d".

The money in an account that earns 4.4% interest per year = 22500

The rest into an account that earns 6% interest per year = 13500

Step-by-step explanation:

Interest = Principal × Rate × Time

Let x = money saved in account A

Let y = money saved in account B

Brandon has 36000 to invest and wants to earn 5% interest per year

x + y = 36000..... Equation 1

x = 36000 - y

He will put some of the money into an account that earns 4.4% interest per year and the rest into an account that earns 6% interest per year.

Hence:

4.4% × x × 1 + 6% × y × 1 = 36000 × 5% × 1

0.044x + 0.06y= 1800....... Equation 2

Substitute 36000-y for x in Equation 2

0.044(36000 - y) + 0.06y = 1800

1584 -0.044y + 0.06y = 1800

-0.044y + 0.06y = 1800 - 1584

0.016y = 216

y = 216/0.016

y = 13500

Note that:

x = 36000 - y

x = 36000 - 13500

x = 2250

Therefore,

The money in an account that earns 4.4% interest per year = 22500

The rest into an account that earns 6% interest per year = 13500

Step-by-step explanation:

Dilation is a transformation in which the size of a given figure is either increased or decreased by a scale factor.

Given that the length of sides of the smaller triangle are; 5, 13, 12.

Given also that the length of the dilated triangle are; x, blank, 18.

Comparing the length of the last sides of the two triangles, we have;

(scale factor x 12) + 12

                        = (\(\frac{1}{2}\) x 12) + 12

                        = 6 + 12

                        = 18

Thus the scale factor for the dilation is \(\frac{1}{2}\). So that:

x = (\(\frac{1}{2}\) x 5) + 5

   = 2.5 + 5

   = 7.5

x = 7.5

And also,

blank = (\(\frac{1}{2}\) x 13) + 13

          = 6.5 + 13

blank  = 19.5

Therefore, the length of the sides of dilated triangle are: 7.5, 19.5, 18

#3) Find the polynomial with roots 0, -3 and 5

When the input is 2 in the function f(x) = 6 + x, the output is 8.

In the given function, f(x) = 6 + x, the variable x represents the input or independent variable, and f(x) represents the output or dependent variable. To find the output when the input is 2, we substitute 2 into the function.

By plugging in 2 for x in the function f(x) = 6 + x, we get f(2) = 6 + 2. Simplifying the expression, we find f(2) = 8.

This means that when the input value is 2, the function evaluates to 8. The function f(x) adds 6 to the input value x, resulting in an output value equal to the sum of 6 and the input. Therefore, when the input is 2, the output of the function is 8.
