Step-by-step explanation:
The frequency table is attached below.
We have to calculate, the probability that the student preferred morning classes given he or she is a junior.
i.e ![P(\text{Morning }|\text{ Junior})](https://tex.z-dn.net/?f=P%28%5Ctext%7BMorning%20%7D%7C%5Ctext%7B%20Junior%7D%29)
We know that,
![P(A\ |\ B)=\dfrac{P(A\ \cap\ B)}{P(B)}](https://tex.z-dn.net/?f=P%28A%5C%20%7C%5C%20B%29%3D%5Cdfrac%7BP%28A%5C%20%5Ccap%5C%20B%29%7D%7BP%28B%29%7D)
So,
![P(\text{Morning }|\text{ Junior})=\dfrac{P(\text{Morning }\cap \text{ Junior})}{P(\text{Junior})}](https://tex.z-dn.net/?f=P%28%5Ctext%7BMorning%20%7D%7C%5Ctext%7B%20Junior%7D%29%3D%5Cdfrac%7BP%28%5Ctext%7BMorning%20%7D%5Ccap%20%5Ctext%7B%20Junior%7D%29%7D%7BP%28%5Ctext%7BJunior%7D%29%7D)
Putting the values from the table,
![\dfrac{P(\text{Morning }\cap \text{ Junior})}{P(\text{Junior})}=\dfrac{\frac{16}{143}}{\frac{26}{143}}=\dfrac{16}{26}=0.615](https://tex.z-dn.net/?f=%5Cdfrac%7BP%28%5Ctext%7BMorning%20%7D%5Ccap%20%5Ctext%7B%20Junior%7D%29%7D%7BP%28%5Ctext%7BJunior%7D%29%7D%3D%5Cdfrac%7B%5Cfrac%7B16%7D%7B143%7D%7D%7B%5Cfrac%7B26%7D%7B143%7D%7D%3D%5Cdfrac%7B16%7D%7B26%7D%3D0.615)
Well i don’t know i just need me pints but sorry i’m so sorry
The volume of the sphere with the given value of diameter is to the nearest tenth is 3052.1cm³.
Option C is the correct answer.
<h3>What is the volume of the sphere?</h3>
The volume of the sphere is the amount of space occupied within the sphere.
Volume of sphere is expressed as;
V = (4/3)πr³
Where r is the radius and π is pi ( π = 3.14 )
Given that;
- Diameter of the sphere d = 18cm
- Radius r = d/2 = 18cm/2 = 9cm
- Constant pi π = 3.14
- Volume V = ?
V = (4/3)πr³
V = (4/3) × 3.14 × 9cm)³
V = (4/3) × 3.14 × 729cm³
V = 3052.1cm³
Therefore, the volume of the sphere with the given value of diameter is to the nearest tenth is 3052.1cm³.
Option C is the correct answer.

Answer:
Question 1: 11%
Question 2: 89%
Question 3: 43%
Question 4: 11%
Step-by-step explanation:
Looking at picture 1, we need to find the crossing point between -1.2 and 0.05. That has 0.1056, which is the same as 10.56%. 10.56% rounds to 11%, so C is our answer.
Picture 2 has the same chart, but we just need to find the inverse, since the inequality sign is flipped. 100 - 10.56 is 89.44%, which rounds to 89%, so D is the answer for Picture 2.
Picture 3 has two tables. 0.73 has 76.73% and -0.41 has 34.09%. Subtract 34.09% from 76.73% to get 42.64% That rounds to 43%, so A is the answer.
Picture 4 essentially has the same expression as Picture 2 (only the sign has switched): P(z ≥ 1.25). The meeting point is 89.44%. Now, subtract that from 100 to get 10.56%, which rounds to 11%. C is our answer for Picture 4.
I hope this helps you! ^w^
