<u>Answer-</u>
<em>The height of the prism is</em><em> 6 units</em>
<u>Solution-</u>
As the base of the prism is a hexagon consisting of 2 congruent isosceles trapezoids.
So,
And,
Also,
Putting all the values,
As the volume is given, so
Answer:
z(s) is in the rejection region. We reject H₀. We dont have enought evidence to support that the cream has effect over the recovery time
Step-by-step explanation:
Sample information:
Size n = 100
mean x = 28,5
Population information
μ₀ = 30
Standard deviation σ = 8
Test Hypothesis
Null Hypothesis H₀ x = μ₀
Alternative Hypothesis Hₐ x < μ₀
We assume CI = 95 % then α = 5 % α = 0,05
As the alternative hypothesis suggest we should develop a one tail-test on the left ( we need to find out if the cream have any effect on the rash), effects on the rash could be measured as days of recovery
A z(c) for 0,05 from z-table is: z(c) = - 1,64
z(s) = ( x - μ₀ ) / σ/√n
z(s) = ( 28,5 - 30 ) / 8/√100
z(s) = - 1,5 * 10 / 8
z(s) = - 1,875
Comparing z(s) and z(c)
|z(s)| < |z(c)| 1,875 > 1,64
z(s) is in the rejection region. We reject H₀. We dont have enought evidence to support that the cream has effect over the recovery time

Answer:
her score in sixth game is 270
Step-by-step explanation:
The computation of the Jasmine score in her sixth game is shown below:
Let us assume her sixth game score is x
And, the first five games are 252, 227, 210, 239, 242
And, the average score is 240
So, the following formula should be used
(252 + 227 + 210 + 239 + 242 + x) ÷ 6 = 240
252 + 227 + 210 + 239 + 242 + x = 240 × 6
252 + 227 + 210 + 239 + 242 + x = 1,440
x = 270
Hence, her score in sixth game is 270
