Answer:
4) 95*.6=57
5) 60-18=42 42/60=70%
6) 26800-5500=21300 21300*.15=3195$
9)9200*.07=644 644+800=1444
3) 36*.75=27ft
Answer:
0
Step-by-step explanation:
It would have zero because the circle and line never interesect the x-axis together.
Since it is observed that I z I = 3.464 > 1.96 it is concluded that the null hypothesis is rejected.
Therefore we reject John's claim.
Here:
we can use 1 sample proportion test to check the claim of John
H₀ : p₀ = 0.4
H₁ : p₀ ≠ 0.4
Test statistic is
z = p - p₀/√p₀(1-p₀)n
Let X be the random variable denoting the number of heads.
Now p = X/n
= 8/50
= 0.16
p₀ = 0.4
1-p₀ = 1-0.4
= 0.6
z = -3.464
since it is observed that I z I = 3.464 > 1.96 it is concluded that the null hypothesis is rejected.
Therefore we reject John's claim.

If I did my math correctly I believe your answer will be C. :)
