LAST ATTEMPT MARKING AS BRAINLIEST!! (Graph the image of the figure using the dilation given)

Answer:

\(n=(\frac{1.960(80)}{25})^2 =246.73 \approx 247\)

So the answer for this case would be n=247 rounded up to the nearest integer

Step-by-step explanation:

We know that the standard deviation is :

\(\sigma = 80\) represent the deviation

The margin of error is given by this formula:

\( ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}\)    (a)

And on this case we have that ME =25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

\(n=(\frac{z_{\alpha/2} \sigma}{ME})^2\)   (b)

The critical value for 95% of confidence interval now can be founded using the normal distribution and the critical value would be \(z_{\alpha/2}=1.960\), replacing into formula (b) we got:

\(n=(\frac{1.960(80)}{25})^2 =246.73 \approx 247\)

So the answer for this case would be n=247 rounded up to the nearest integer

Answer:

Fail to reject the null hypothesis because the p-value =0.10 is more than the significance level α=0.05.

Step-by-step explanation:

The significant level for this case study is 5% - 0.05. If the results gotten is less than the significance level, we reject the null hypothesis, but if greater, we fail to reject the null hypothesis.

In this case study, the p-value is 0.10 which is a lot higher than 0.05, thus we will fail to reject the null hypothesis because the p-value =0.10 is more than the significance level α=0.05.

Answer:

Explanation:

Here, we want to get the maximum/minimum value of the given function

The highest power of the function is 2 and that means it is a quadratic function

Given that the leading coefficient is negative, the function does not have a minimum but a maximum value

To get the maximum value (the y-coordinate of the vertex), we use the following formula:

a represents the leading coefficient

b represents the coefficient of x

Substituting the values, we have it that:

We now substitute this value into the original equation

We have this as follows:

If each box contains 20 bars and Pamela's mother purchased 5 boxes

To get the number of candy bars Pamela's mother have, we will simply multiply the number of box by the number oc candy in each box

That is; 5 x 20bars = 100 candy bars

Hence Pamela's mother have 100 candy bars

The numeric value of the function f(x) = 14/[3 + ae^(kx)] at x = 2 is given as follows:

f(2) = 0.172.

The function for this problem is defined as follows:

f(x) = 14/[3 + ae^(kx)]

When x = 0, y = 2, hence we can obtain the coefficient a as follows:

2 = 14/(3 + a)

6 + a = 14

a = 8.

Hence:

f(x) = 14/[3 + 8e^(kx)]

When x = 1, y = 1/2, hence the coefficient k is given as follows:

0.5 = 14/(3 + 8e^k)

1.5 + 4e^k = 14

4e^k = 12.5

e^k = 12.5/4

k = ln(12.5/4)

k = 1.14.

Hence:

f(x) = 14/[3 + 8e^(1.14x)]

Then the numeric value of the function at x = 2 is given as follows:

f(2) = 14/[3 + 8e^(1.14(2))]

f(2) = 0.172.

Step-by-step explanation:

\(y=(\frac{1}{g} )x\)

Constant up a proportionally is  \(\frac{1}{g}\).

(a) The null hypothesis is that there is no difference between the population means for the math scores and the writing scores, while the alternative hypothesis is that there is a difference.

(b) The test statistic is:

t = (μ1 - μ2) / sqrt(s1^2/n1 + s2^2/n2)

(a) To test for a difference between the population mean for the math scores and the population mean for the writing scores, we can use a two-sample t-test. The null hypothesis is that there is no difference between the population means, while the alternative hypothesis is that there is a difference.

(b) To calculate the test statistic, we first need to find the sample means and sample standard deviations for the math and writing scores. Let's call the sample mean of the math scores μ1, and the sample mean of the writing scores μ2. Then, the test statistic can be calculated using the formula:

t = (μ1 - μ2) / sqrt(s1^2/n1 + s2^2/n2)

where s1^2 is the sample variance of the math scores, n1 is the sample size for the math scores, s2^2 is the sample variance of the writing scores, and n2 is the sample size for the writing scores.

Option A. To translate a figure 4 units to the left, we need to subtract 4 from the x-coordinates of each vertex.

The original vertices are:

(4, 4), (4, 2), and (6, 3)

Subtracting 4 from the x-coordinates, we get the new vertices:

(0, 4), (0, 2), and (2, 3)

To understand how to translate a figure, it is helpful to visualize the original and new positions of the figure in a coordinate plane. In this case, the original triangle has vertices (4, 4), (4, 2), and (6, 3) as shown below:

   (4,4)

     / \

    /   \

(4,2)----- (6,3)

To translate this triangle 4 units to the left, we need to subtract 4 from the x-coordinates of each vertex. This will shift the entire triangle to the left by 4 units.

So, the new x-coordinates of the vertices become:

x-coordinate of (4, 4) - 4 = 0

x-coordinate of (4, 2) - 4 = 0

x-coordinate of (6, 3) - 4 = 2

The y-coordinates of the vertices remain the same.

Therefore, the new vertices of the triangle are:

(0, 4), (0, 2), and (2, 3)

The percentage that can be filled with $3 in 1990 is: 29.41%

To calculate percentage growth rate:

Beginning:

Calculate the difference (increase) between the two numbers you are comparing. after that:

Divide the increment by the original number and multiply the result by 100. Growth rate = increment / original number * 100.  

We are told that it cost $3 to fill a gas tank as at 1970.

Now, there was a percentage price increase of (78.8 - 23.1)% = 55.2% from 1970 to 1990. Thus:

Cost of a gallon in 1970 = $0.36

Thus, number of gallons bought with $3 = 3/0.36 = 8.33 gallons at full tank

Now, in 1990, the cost is $1.23 and as such:

Quantity that can be bought = 3/1.23 = 2.45 gallons

Percentage of tank filled = 2.45/8.33 * 100% = 29.41%

288π or 904.78

Step-by-step explanation:

We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is \(\frac{4}{3}\) × π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.

Volume = \(\frac{4}{3}\) × π × r³

→ Let's substitute in the values

Volume = \(\frac{4}{3}\) × π × 6³

→ Simplify

Volume = \(\frac{4}{3}\) × π × 216

→ Simplify further

Volume = 288π or 904.78

The amount of air can the sphere shape beach ball hold is 208π or 904.78 inches.

The "set of all  points  in 3 dimensional space is lying the same distance from the given points or center" is called sphere.

According to the question,

Diameter of sphere shape beach ball is 12inches

Radius of sphere shape beach ball is 12/2 = 6inches

Volume of sphere = \(\frac{4}{3}\) × π × r³  

= \(\frac{4}{3}\) × \(\frac{22}{7}\) × (6)³

= 904.78inches

Hence, the amount of air can the sphere shape beach ball hold is 208π or 904.78 inches.

The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).

First, let's find the slope of the line using the formula:

slope (m) = (change in y) / (change in x)

m = (0 - 4) / (5 - 3)

m = -4 / 2

m = -2

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Using the point (3, 4) as our reference point, we have:

y - 4 = -2(x - 3)

Expanding the equation:

y - 4 = -2x + 6

Simplifying:

y = -2x + 10

Now, let's check the given options to find the linear function with the same y-intercept:

Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)

The y-intercept is the same as the given line (10). So, this option is correct.

Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)

The y-intercept is not the same as the given line. So, this option is not correct.

Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

The average rate of change of the school's enrollment during this time period is -49 students per year. This means that on average, the enrollment at the college has been decreasing by 49 students per year.

To determine the average rate of change of the school's enrollment during the given time period, we can use the formula:

Average rate of change = (Change in enrollment) / (Change in time)

The change in enrollment is calculated by subtracting the initial enrollment from the final enrollment, while the change in time is calculated by subtracting the initial year from the final year.

Given that in 2004 there were 975 students enrolled and in 2009 there were 730 students enrolled, we can calculate the change in enrollment:

Change in enrollment = 730 - 975 = -245 students

The change in time can be calculated as:

Change in time = 2009 - 2004 = 5 years

Now we can calculate the average rate of change:

Average rate of change = (-245 students) / (5 years) = -49 students per year

Therefore, the average rate of change of the school's enrollment during this time period is -49 students per year. This means that on average, the enrollment at the college has been decreasing by 49 students per year.

Step-by-step explanation:

Lilia scores 20 points, Carol scores 10 points.

And the expressions used to find these points:

x = y - 15

z = (1/2)x

where, x, y , z are the points scored by Lilia, Bob and Carol respectively.

Let Lilia scores 'x' points, Bob scores 'y' points and Carol scores 'z' scores.

Bob scores 35 points.

So, we get an expression y = 35

Lilia scores 15 points fewer than Bob

So, we get an expression,

x = y - 15

But y = 35

So, x = 35 - 15

x = 20

Carol scores half as many points as Lilia.

So, we get an expression,

z = (1/2)x

substitute above value of x.

z = 1/2 * (20)

z = 10 points

Therefore, Lilia scores 20 points, Carol scores 10 points.

Step-by-step explanation:

The vertex form of the quadratic equation is:

f(x) = 3*(x - 1)² + 12

Remember that for a quadratic equation whose vertex is at (h, k) and the leading coefficient is a, we can write it in the vertex form as:

y = a*(x - h)² + k

Here we have:

f(x) = (3x-9)(x+1)

We can rewrite that as:

f(x) = (3x - 3*3)(x+1)

f(x) = 3(x - 3)*(x + 1)

Thus the leading coefficient is 3.

The x-value of the vertex is the midpoint the two x-intercepts x = 3 and x = -1, then:

h = (3 - 1)/2

h = 2/2

h = 1

And to get the y-value, we need to evaluate in x = 1.

f(2) = 3*(1 - 3)*(1 + 1)

f(2) = 3*-2*2 = -12

So the vertex is (1, 12), then the vertex form is:

f(x) = 3*(x - 1)² + 12
