Answer:
B. 2, 4, 5, 7
Step-by-step explanation:
6x<48
Divide by 6 on both sides:
x < 8 (excluding 8)
You can test values greater than 8, and if it yields false, then try different numbers.
Hope this helps!

Answer:
The volume of air that the beach ball will hold is ![36,000 \pi\ cm^{3}](https://tex.z-dn.net/?f=36%2C000%20%5Cpi%5C%20cm%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of a sphere ( a giant beach ball with air) is equal to
![V=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
we have
![r=30\ cm](https://tex.z-dn.net/?f=r%3D30%5C%20cm)
![V=\frac{4}{3}\pi (30^{3})](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%2830%5E%7B3%7D%29)
![V=36,000 \pi\ cm^{3}](https://tex.z-dn.net/?f=V%3D36%2C000%20%5Cpi%5C%20cm%5E%7B3%7D)
Answer:
0.41053
Step-by-step explanation:
![z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
![z=\frac{25-26.9}{8.4}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B25-26.9%7D%7B8.4%7D)
z=-0.2262
P(X<25)=P(z<-0.2262)
=1-P(z<0.2262)
=1-0.58947
P(x<25) = 0.41053
The probability that a randomly selected person is under the age of 25 is 0.41053.
The student can choose any one of 3 sandwiches. For each of those . . .
He can choose any one of 3 soups. For each of those . . .
He can choose any one of 4 salads. For each of those . . .
He can choose either one of 2 drinks.
Total possibilities = (3 x 3 x 4 x 2) = <em><u>72 different lunches</u></em>.
