Considering the margin of error, it is found that the 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).

It is given by the sample statistic plus/minus the margin of error.

In this problem, 68% of adults say such vaccines should be required, with a margin of error of 3.1%, hence:

68% - 3.1% = 64.9%.

68% + 3.1% = 71.1%.

The 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).

Answer: 263.75

Step-by-step explanation:

because i know

The decimal form of 26.375% is 0.26375.

Let, x be a number.

Now, if we want to convert x% to decimal, then we have to divide x by 100.

To convert the given percentage into decimal, we have to divide the given percentage by 100.

∴ 26.375% = [tex]\frac{26.375}{100}[/tex] = 0.26375

Hence, 26.375% = 0.26375

The ratio between the surfaces areas of the two prisms is equal to 6.25.

The ratio between the volumes of the prisms is:

[tex]R_v = \frac{375 in^3}{24 in^3} = 15.625[/tex]

This number is equal to the cube of the scale of dilation applied to the dimensions of the smaller prism, so the scale factor is:

[tex]\sqrt[3]{15.625} = 2.5[/tex]

And the ratio between the areas should be the square of the scale factor, then we will have that the ratio between the surface areas of the two prisms is:

There is no difference in height that is not sufficient to meet the slope constraint if Matt wants to start a zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

We know the slope can be evaluated using:

[tex]\rm Slope = \frac{Change \ in \ y \ axis}{Change \ in \ x \ axis}[/tex]

Change in y-axis = difference in height

Change in y-axis = 16 - 10

                            = 10 feet

Change in x-axis = distance between tress

Since the data is not given.

So, the height difference is insufficient to keep the slope constraint.

Thus, there is no difference in height that is not sufficient to meet the slope constraint if Matt wants to start a zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint.

Step-by-step explanation:

Answer:

x=1,y=-1

Step-by-step explanation:

To use the elimination method, we make the coefficient of y the same:

But they are already the same just with different signs.

So we add the 2 equations to make equation 3:

5x + y = 4

+    +   =  +

6x - y = 7

11x = 11

Solve for x:

x = 1

Substitute the value of x into either equation 1 or 2 to find y:

I chose 1:

5(1)+y=4

5+y=4

y=4-5

y=-1

Our answer is x=1,y=-1

Substituting these values into equation 2 verifies our answer

The linear function predicts that there would be 92857146 female cane toads in 2000 while the exponential function predicts that there would be 34898137 female cane toads in 2000.

From the question, we have the following points

(t, f(t)) = (0,50) and (70, 100000000)

The linear function is then calculated as:

f(t) = [f(t2) - f(t1)]/[t2 - t1](t - t1) + f(t1)

This gives

f(t) = [100000000 - 50]/[70 - 0](t - 0) + 50

Evaluate

f(t) = 1428570.71t + 50

Hence, the linear function is f(t) = 1428570.71t + 50

The exponential function is given as:

f(t) = 50(1.23)^t

So, the parameters are:

The exponential function is calculated as:

f(t) = 1428570.71t + 50

So, the parameters are:

When the population of an entity is being model, it is best to use the exponential model, because the populations would grow exponentially for some time, and then stop growing at some point

Hence, the more appropriate model is the exponential model.

The year 2000 is 65 years from 1935.

So, we have:

t = 65

For the exponential model, we have:

f(t) = 50(1.23)^t

The equation becomes

f(65) = 50(1.23)^65

Evaluate

f(65) = 34898137

For the linear function, we have:

f(t) = 1428570.71t + 50

The equation becomes

f(65) = 1428570.71 * 65 + 50

Evaluate

f(65) = 92857146

This means that. there would be 34898137 female cane toads in 2000 according to the exponential function.

Step-by-step explanation:

Sum of all angles of triangle = 180°

15x + 3 + 3x - 1 + 52 = 180

15x + 3x + 3 - 1 + 52= 180

Combine like terms.

   18x + 54 = 180

To find the vlaue of x, we have to islolate x

Step1: Subtract 54 from both sides

          18x = 180 - 54

          18x = 126

Step2: Divide both sides by 18

             x = 126/18
