Answer:
Fraction: 10 and 5/8
Step-by-step explanation:
17 × 5/8
85/8
Bobby should grow an amount greater than 70-61 = 9 inches to become taller than 70 inches. Therefore, the correct answer is that Bobby must grow an amount of x> 9 inches to be taller than 70 inches.
Answer:
Slope: 0
Step-by-step explanation:
(-3,5) (4,5)
y2-y1/x2-x1
5-5/4+3=0/7
0/7 simplifies to 0.
So the slope of the line (-3,5) (4,5) is 0.
Hope this helps! ;)
Answer:
52
Step-by-step explanation:
13 = x/4
To isolate the x, you have to multiply 4 on each side.
x/4 * 4= x
13 * 4 = 52
x = 52
Answer: p = 0.73
Step-by-step explanation:
Given that,
73% of the audience was under 20 years old :
so, probability (p) = 0.73
n = 146
Mean of the distribution of sample proportion = ?
According to central limit theorem,
np(1-p) ≥ 10
146 × 0.73(0.27) ≥ 10
28.77 ≥ 10
∴ Central limit theorem assumes that the sample distribution of the sample proportion is normally distributed.
Hence, the mean of the distribution of sample proportion:
μ = p = 0.73
