Answer:
Remi needs 15 cm of wood to be cut for the shelf.
Step-by-step explanation:
We have drawn the triangle for your reference.
Now Given:
Base measure (BC) =30 cm
Slant height (AB) = 24 cm
Slant height (AC) = 18 cm
Also Given horizontal shelf halfway between the base and the top.
In the triangle drawn horizontal shelf is denoted by DE.
We need to find the measure of DE.
Now we know that horizontal shelf halfway between the base and the top.
Hence by Midpoint theorem which states that;
"The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side."
Substituting the value we get;
Hence Remi needs 15 cm of wood to be cut for the shelf.
To answer the question above, we will have to use some calculus approach to this problem.
<span>volume of sphere = (4/3)(pi)(radius^3) = (4/3)(pi)(9^3) = 972pi </span>
<span>mass = (density)(volume) = (972pi)(1,000) = 972,000pi </span>
<span>force = (mass)(acceleration or gravity here) = (972,000pi)(9.8) = 9,525,600pi </span>
<span>work = (force)(distance) = (9,525,600pi)(4.5) = 42,865,200pi J
</span>

Answer:
B
Step-by-step explanation:
Here, we are to give the reason why we would reject the null hypothesis during the hypothesis testing.
In considering whether to accept the null hypothesis or reject the null hypothesis, we have to take into consideration two things.
The p-value and the alpha value. The p-value refers to the probability which is directly obtainable from the standard score which is referred to as the z-score while the alpha refers to the level of significance.
Now, when the p-value is less than alpha, we simply reject the null hypothesis and accept the alternative hypothesis. In a case however, we have the value of p greater than or equal to the significance level alpha, we simply accept the null hypothesis in this case.
The question asks for a rejection case and this can happen only when the p-value is less than the level of significance alpha
