Answer:

B. 3x -7y < -21

Step-by-step explanation:

For this problem, a quick way to the correct answer choice is to determine on which side of the y-intercept the equation tells you the solution lies. That is ...

set x=0
divide by the coefficient of y

Doing this transforms the answer choices to ...

A: y < 3

B: y > 3

C: y > -3

D: y < -3

The graph clearly shows the solution space on the y-axis is in the region y > 3, matching choice B.

Oliga [24]

Answer:

no of sample within two percentage points is 5409

no of sample not use prior estimates is 8321

Step-by-step explanation:

Given data

E = 2% = 0.02

male m = 21.2 % = 0.212

female f = 19.7 % = 0.197

to find out

no of sample within two percentage points and if does not use any prior estimates

solution

first we calculate no of sample within two percentage points

we know Z critical value for 99% is 2.58

so no of sample will be

n = (Z / E )² × m(1-m) + f ( 1-f )

put all the value we get no of sample

n = (2.58 / 0.02 )² × 0.212 ( 1 - 0.212 ) + 0.197 ( 1 - 0.197 )

n = 16641 ×0.3250

no of sample within two percentage points is 5409

in 2nd part no of sample not use prior estimates

here than f and m will be 0.5

than

n = (Z / E )² × m(1-m) + f ( 1-f )

put all value

n = (2.58 / 0.02 )² × 0.5 ( 1 - 0.5 ) + 0.5 ( 1 - 0.5 )

n = 16641 × 0.5

no of sample not use prior estimates is 8321

mars1129 [50]

Answer:

9 dollars

Step-by-step explanation:

Hello you did not provide the options for me to select from. But I have gone ahead to calculate how much jessica would pay for her cookie dough.

I used this formula to arrive at this answer.

Cost of dough = quantity x price per ounce

Quantity = 6 ounces

Price per ounce = 1.5 dollars

Cost of dough = 6 x 1.50

= $9

Jessica is going to pay 9 dollars for her cookie dough
