The 48 members of the glee club are trying to raise at least $6,000 so they can compete in the state championship. They already

ddd [48]

Step-by-step explanation:

48: the number of members

1,210: amount of money they already have

6,000: amount they need

by simply dividing the goal with amount of people, you will get the amount each person needs to make.

6000 ÷ 48 = 125

48x - 1,210 = 6000

x = how much each person needs to make

48 × 125 = 6000

i think this is what your looking for? if not just comment dont report and i will ask for more details.

If 20% of X =y, then y% of 20 is the same as:

coldgirl [10]

Answer:

4% of x

Step-by-step explanation:

20% of x

20% of x = 0.2x
20% of x = y ⇒ 0.2x = y

y% of 20

y% of 20 = 20*y/100 = 0.2y
0.2y = 0.2*0.2x = 0.04x
y% of 20 = 4% of x

Hope it is what you are looking for

The numerical course grades in a statistics course can be approximated by a normal model with a mean of 70 and a standard deviat

Naily [24]

Answer:

A = 82.82

B = 72.53

C = 61.58

D = 53.55

Step-by-step explanation:

First, determine the percentile at which the cutoff grade in each letter grade interval falls on and find the equivalent z-score:

A: (100-10) = 90-th percentile

z-score = 1.282

B: (100-10-30) = 60-th percentile

z-score = 0.253

C : (100-10-30-40) = 20-th percentile

z-score = -0.842

D: (100-10-30-40-15) = 5-th percentile

z-score = −1.645

The value 'X' for each cutoff can be found by applying the z-score equation:

$z= \frac{X- \mu }{SD}$

Where μ is the mean and SD is the standard deviation

Therefore, the cutoffs are:

$1.282= \frac{X(A)- 70}{10}\\X(A) = 10*1.282 +70\\X(A) = 82.82\\\\0.253 = \frac{X(B)- 70}{10}\\X(B) = 10*0.253 +70\\X(B) = 72.53\\\\0.253 = \frac{X(C)- 70}{10}\\X(C) = 10*-0.842 +70\\X(C) = 61.58\\\\0.253 = \frac{X(D)- 70}{10}\\X(D) = 10*-1.645 +70\\X(D) = 53.55\\$
