Step-by-step explanation:
volume of sphere = 288
based on formula, V = 4/3πr³
288 = 4/3(3.14)r³
288 = 4.187(r³)
r³ = 288/4.187
r =
![\sqrt[3]{68.78}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B68.78%7D%20)
r = 4.09
= 4.1
Answer:
$1917.60
Step-by-step explanation:
Interest = Principal x Rate x Time
103.55 = (.05)(13/12)P
103.55 = .054P
P = 1917.60
X meaning the letter X that’s how math works OR either X as for multiplication so it would be like -80x get it or no
Answer:
a. 17 b. 16/24
Step-by-step explanation:
a. Find the midpoints of each class interval which is:
7.5 x 2 = 15
12.5 x 9 = 112.5
17.5 x 5 = 87.5
22.5 x 5 = 112.5
27.5 x 3 = 82.5
Add all of these up to give 410
Add up the total of the frequency column which is 24
410 / 24 = 17.0833.....
Rounded to 2 significant figures, the answer is 17
b. Add together all the people under 20 which totals to 16 and put this over the total of 24 to give the fraction 16/24
