Answer: 308cm

Step-by-step explanation: The formula to find the curved surface area of a cylinder is 2πr × h. The formula for curcufrence is 2πr.

So,

2πr (circumfrence)= 44cm.

Height= 7cm.

2πr × h = 44 x 7 = Curved surface area.

Curved surface area= 308cm

What is the equation for the line of curve of best fit for the following data?

Vlad [161]

Correct answer:
Option B. y = 50.5x - 240

If we plot these points on a graph, we will observe that these points mostly lie in a straight line. Therefore, a straight line will be the best fit for the given ordered pairs. The equation of the best fit can be found using any tool like Statistica, Stata or Excel. I have used Microsoft Excel to plot the lines and find the equation of best fit. The graph and equation are shown below in the image attached with:

3x+17 less than or equal to 2(1-x)

MrRa [10]

Answer:

x ≤ -5

Step-by-step explanation:

According to given condition:

3x + 17 ≤ 2(1 - x)

By simplifying:

3x + 17 ≤ 2 - 2x

Adding 2x - 17 on both sides we get:

3x + 2x ≤ 2 - 17

5x ≤ - 15

Dividing both sides by 5 we get:

x ≤ -5

An administrator at a local high school wants to investigate whether there is an association between the grade level of a studen

Nataliya [291]

Answer:

Step-by-step explanation:

The following is how the p-value should be interpreted:

The probability of getting the test statistics value at least as intense as it might have been acquired during the test, assuming the null hypothesis is true, is considered as the p-value.

Null hypothesis

$\mathbf{H_o :}$ A student's grade level has no bearing or association on how they commute to school.

Alternative hypothesis;

$\mathbf{H_1: }$ There is a link between a student's grade level and the way they get to school.

The test statistic's value is 14.63, and the p-value is 0.2636.

As a result, the p-value is interpreted as that of option c in the question.
