trapecia [35]

Answer: 3.7 in.

Step-by-step explanation:

Given, A toy designer is creating a basketball plushy. The designer has fabric that measures 171.9 sq. in.

To find: The maximum radius of the basketball that the designer can create.

For this, Surface area of basketball = area of fabric

Formula: Surface area of sphere = $4\pi r^2$ , where r is the radius.

Then, $4\pi r^2=171.9$

$r^2=\dfrac{171.9}{4\pi}=\dfrac{171.9}{4\times3.14}\\\\\Rightarrow\ r=13.6863057325\\\\\Rightarrow\ r=\sqrt{13.6863057325}=3.69950074098\approx3.7$

Hence, the maximum radius of the basketball that the designer can create is 3.7 in.

Use the t-distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from r

attashe74 [19]

The test statistics and the p-value from the research sampling will be 1.57 and 0.119.

<h3>What is test statistic?</h3>

It should be noted that a test statistic simply means a number that's used to describe how the observed value is far from the null hypothesis.

In this case, the test statistics is 1.57. The p value will be:

= 2 × 0.0593

= 0.119

Therefore, the test statistics and the p-value from the research sampling will be 1.57 and 0.119.

A construction crew is extending the length of the center line on a highway. The length of the line starts out as 6 meters long,

Kryger [21]

The equation that represents the relationship between x and y is $y=\frac{11}{20}x+6$

Explanation:

Given that a construction crew is extending the length of the center line on a highway.

The length of the line starts out as 6 meters long, which is represented on a coordinate plane as the point (0,6). The crew works for 20 minutes and the line is now 17 meters long, which is represented as the point (20,17).

Let x represents the number of minutes spent working.

Let y represents the length of the line in meters.

We need to determine the equation that represents the relationship between x and y.

The equation can be determined using the formula,

$y-y_1=m(x-x_1)$
