Step 1: Problem
There is a class with 6 women and 12 men. a) If I randomly pick 5 students, with replacement. What is the probability that at least 4 of them will be man? b) If I randomly pick 6 students, what is the probability that at least one of them will be a man?
Step 2: Concept
The total monthly cost of the two companies will be the same for 30 texts.
<u>Step-by-step explanation:</u>
It is given that,
- The variables used here are x and y.
- y represent the total monthly cost.
we know that, x must represent the number of texts in a month.
The monthly texting plan of All Star Cell is $11 per month and $0.25 per text.
⇒ y = 11 + 0.25x --------(1)
The monthly texting plan of Top Line Cell is $14 per month and $0.15 per text.
⇒ y = 14 + 0.15x --------(2)
<u>To find the no.of texts for which the total monthly cost of the two companies be the same :</u>
⇒ Total cost of All Star Cell = Total cost of Top Line Cell
⇒ 11 + 0.25x = 14 + 0.15x
⇒ 0.25x - 0.15x = 14 - 11
⇒ 0.1x = 3
⇒ x = 3 / 0.1
⇒ x = 30 texts.
The total monthly cost of the two companies will be the same for 30 texts.
Answer:
or 
Step-by-step explanation:
<u>Synthetic division:</u>
-5 | 1 11 25
____<u>-5 -30</u>
1 6 | -5
Therefore, or 
<u>Long division:</u>
n+5 | n² + 11n + 25
- <u>n² + 5n____</u> <-- n
6n + 25
- <u> 6n + 30</u> <-- 6
-5 | n+6
Therefore, or
Answer:
The answer is 20.
Step-by-step explanation:
10+12=22 round 22 to the nearest tenths and the answer is 20.
I hope is right.
if its diameter is 8 cm, then its radius is half that, or 4 cm.
