what did u get?
Answer:
19
Step-by-step explanation:
Add up all the numbers:
3,2,2,2,1,1,1,4,2,1
Then you get 19.
Or you can say it as
3^2 + 2^4 + 1^4 + 4
<span>x^2 - 3x - 28 = </span><span>(x - 7)(x + 4)
answer
first one
</span><span>(x - 7)(x + 4)
</span>
hope it helps
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
