"In one statistics course, students reported studying an average of 9.92 hours a week, with a standard deviation of 4.54. Treati
Rudik [331]

Answer:

66.28% of students study more than 8 hours

Step-by-step explanation:

The percent of students study more than 8 hour can be calculated as

P(X>8)=?

P(X>8)=P((X-mean)/sd>(8-9.92)/4.54)

The calculated z-score is -0.42.

P(X>8)=P(Z>-0.42)

P(X>8)=P(0<Z<-0.42)+P(0<Z<∞)

P(X>8)=0.1628+0.5=0.6628.

Thus, 66.28% of students study more than 8 hours.

Which step brings you closest to getting the variable alone on one side of the equation
Oliga [24]

Answer:

Adding 5 from both sides then dividing by 7

Step-by-step explanation:

The best way to isolate x is to add 5 to both sides first:

21 = 7x

Then to isolate x by itself divide both sides by 7

x = 3

That would be the value of x and your final answer.

The table shows a linear relationship between x and y
irga5000 [103]

We have been given a table that shows a linear relationship between x and y. We are asked to find the rate of change change of y with respect to x.

To solve our given problem, we will find the slope of the line passing through the given points.

m=\frac{y_2-y_1}{x_2-x_1}

Let us find slope of line using points (-20,96) and (-2,15).

m=\frac{15-96}{-2-(-20)}

m=\frac{-81}{-2+20}

m=\frac{-81}{18}

m=-4.5

Therefore, the rate of change of y with respect to x is -4.5.
