The average weight of 10 boys is 77.0 pounds. If the

n200080 [17]

Answer:

68 pounds.

Step-by-step explanation:

Find the total weight when there are 10 boys and when there are 9 boys then calculate the difference.

I'll let x = total weight.

$\frac{x}{10}=77\\(10)\frac{x}{10}=77(10)\\x=770\\\\ \frac{x}{9}=78\\(9)\frac{x}{9}=78(9)\\x=702\\\\ 770-702=68$

Therefore, the youngest boy weighs 68 pounds.

A data set has a mean of 112 and a standard deviation of 2.5.

Ahat [919]

Answer with explanation:

Mean of the data set $\mu$ = 112

Standard Deviation of the data set $\sigma$ =2.5

Since , 50% of data lies on both side of the mean.

Z at 50% = 0.1915

Margin of error for this data set

$=Z_{50 \text{percent}}\times\frac{\sigma}{\sqrt{\mu}}\\\\=0.1915 \times \frac{2.5}{\sqrt{112}}\\\\=0.1915 \times \frac{2.5}{10.58}\\\\=0.1915 \times 0.2362\\\\=0.0452$

Margin of error=0.045(approx)

If f(x) = 3x – 2 and g(x) = 2x + 1, find (f + g)(x). please help :C

Luba_88 [7]

(f+g)(x) = f(x) + g(x)

(f+g)(x) = 3x-2 + 2x+1

(f+g)(x) = (3x+2x) + (-2+1)

(f+g)(x) = 5x - 1
