In 6 months, Simple interest of $6 will be earned for investing $100.
<u>Step-by-step explanation:</u>
Step 1:
Given details are Principal (P) = $100, SI rate (R) = 12%, Time (T) = 6 months = 0.5 years
Step 2:
Calculate Simple Interest by the formula SI = PRT/100
⇒ SI = 100 × 12 × 0.5/100
⇒ SI = $6
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.

Step-by-step explanation: not sure sorry if i get it wrong
V of rectangular prism = l * w * h = 12 * 2 * 312 = 7,488 in³
V of one cube with side lengths 12 = l * w * h = 12 * 12 * 12 = 1,728 in³
Divide the volume of rectangular prism by the volume of the cube.
7488 / 1728 = 13 / 3 or 4.3. . .
