Answer:

3/7 of a dress in one hour

Step-by-step explanation:

(4/7)/(3/4)=x/(4/4)

(4/7)(4/3)=x/1

cross product

4/3*x=(4/7)(1)

4/3x=4/7

x=(4/7)/(4/3)

x=(4/7)(3/4)

x=3/7

Scores are 78,81,83, and 76 what must she earn on the fifth test to earn an average test score of 81

iogann1982 [59]

The average value of a data set is equal to the sum of each entry divided by the number of entries. In this case, we have 5 scores, so we can find set up the following equation where x is the fifth score:

$\dfrac{78+81+83+76+x}{5} = 81$

Now solve for x:

$78 + 81 + 83 + 76 + x = 81(5)$

$318 + x = 405$

$x = 87$

The fifth score must be 87.
