Step-by-step explanation:

for some reason the equation at the top says 7(x+2) but both of the equations at the bottom say 7(x-2)... I'm just going to do 7(x-2)

Emmanuels Work:

7(x-2)=91

distribute the 7 by multiplying both x and -2 by it

7x-14=91

add 14 to both sides

7x=105

divide both sides by 7

x=15

Mauricio's Work:

7(x-2)=91

to get rid of the 7 multiplication, divide both sides by 7

x-2=13

add 2 to both sides

x=15

Question: Edwin usually makes 20 cookies with this recipe, but only wants 5 cookies.
horsena [70]

Answer:

1/2 teaspoons of vanilla would be too much, the correct amount to use would be 0.125 teaspoons.

Step-by-step explanation:

Since 1 stick butter, 1/2 cup sugar, 1/2 teaspoon vanilla, 3 tablespoons milk, 1 1/2 cup flour, 2 teaspoon baking powder, 1/4 teaspoon salt is the regular recipe for 20 cookies, we would first have to divide 20 by 5 which would equal 4. And just like we had to divide the number of cookies down we have to divide the amount of vanilla down. So now we could turn 1/2 into a decimal which is 0.5. And 0.5 divided by 4 is 0.125.

So Edwin would need 0.125 teaspoons of vanilla so 0.5 ( 1/2 ) teaspoons of vanilla would be too much.

Suppose we take repeated random samples of 50 college students from the same population and determine a 95% confidence interval
zzz [600]

Answer:

B. The intervals are centered around the sample mean GPA.

D. 95% of the intervals will contain the population mean in the long run.

Step-by-step explanation:

Confidence interval:

Depends on two things: The sample mean and the margin of error.

Lower end: Sample mean - margin of error

Upper end: Sample mean + margin of error

This means that the intervals are centered around the sample mean.

x% level:

x% of the intervals will contain the population mean in the long run.

So the true statements are:

B. The intervals are centered around the sample mean GPA.

D. 95% of the intervals will contain the population mean in the long run.

Given the line y =2/3x-3
enyata [817]

Answer:

y= -3/2x + 5

Step-by-step explanation:

You do the opposite reciprocal of the original equation's slope.

Then you use the new slope from the point (4,-1) on the graph to find the y-intercept. Which is (0,5).

That gets your answer of -3/2x + 5.
