A scientist selected a random sample of seven varieties of peach ice cream to investigate the relationship between the density,

ValentinkaMS [17]

Answer:

The significance test that would be used to investigate whether there is convincing evidence at 0.05 level of significance that a greater percent of peaches in the ice cream is associated with an increase in the density of the ice cream is option C;

C. A linear regression t-test for slope

Step-by-step explanation:

The linear regression t-test for slope is a test for determining the existence of a statistically significant linear relationship between two variables, a independent variable, X and an dependent variable Y in the following form;

Y = B₀ + B₁·X

The test is used to test the regression line slope where we have;

B₀ = The constant

B₁ = The slope also known as the regression coefficient

The given information tested in the question is if an increase in the peaches in the ice cream is associated with an increase in the density of the ice cream, therefore, the test to investigate the relationship between the rate of both variables is the linear regression t-test for slope.

Therefore, we have

Y = B₀ + B₁·X

Where;

X = The percentage of peaches in the ice cream

Y = The density of the ice cream

What is the value of a? 14 – 2a = 4a – 16

VladimirAG [237]

14 - 2x = 4a - 16

First, add 2a to both sides. / Your problem should look like: $14 = 4a - 16 + 2a$
Second, simplify 4a - 16 + 2a to get 6a - 16. / Your problem should look like: $14 = 6a - 16$
Third, add 16 to both sides. / Your problem should look like: $14 + 16 = 6a$
Fourth, add 14 + 16 to get 30. / Your problem should look like: $30 = 6a$
Fifth, divide both sides by 6. / Your problem should look like: $\frac{30}{6} = a$
Sixth, 6 goes into 5 to get 30, so simplify $\frac{30}{6}$ to 5. / Your problem should look like: $5 = a$
Seventh, switch your sides. / Your problem should look like: $a = 5$

Answer: a = 5

How to find the surface area of a triangular prism using net?

Mazyrski [523]

A net is a pattern made when the surface of a three-dimensional figure or solid is laid out flat showing each face of the figure. It is then possible to use the net to calculate the surface area of the solid.
