The account A has amount $600 and B has $1600.

Step-by-step explanation:

The given equations are:

a+b=2200 ⇒1

0.03a+0.05b=98 or $\frac{3}{100}a$ + $\frac{5}{100}b$ ⇒2

Change the first equation by isolating a,

a = 2200-b. ⇒3

Apply equation 3 in 2,

$\frac{3}{100}(2200-b)$ + $\frac{5}{100}b$ =98.

66- $\frac{3}{100} b$ + $\frac{5}{100}b$ =98.

66+ $\frac{2}{100} b$ = 98.

6600+2b=9800.

2b=9800-6600.

2b=3200.

b=1600.

Substitute b value in equation 3

a=2200-1600.

a=600.

The number of assists per match for the setter on your school's volleyball team has a mean of 58 and a standard deviation of 7.

serious [3.7K]

To get the number of standard deviation that 77 is from the mean, we get the z-score:
z-score is given by
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the value of z from the information above is:
x=77
μ=58
σ=7
z=(77-58)/7=2.7143
