How do you solve 4(6x-1)=120 if you're solving for x

Answers

Answer 1
Answer: 4(6x-1)=120
Multiply the number outside the parenthesis(4) with the numbers inside the parenthesis(6 and -1)
24x-4=120
Add 4 to both sides
24x=124
Divide both sides by 24
Final Answer: x= 5.1667 or 5 1667/10,000

A survey asking 75 people if they like the new school building. This is a binomial experiment.

A binomial experiment is called as such when it satisfies these 4 conditions.
1) There is a fixed number of trials. = 75 people
2) Each trial is independent of each other = own opinion
3) There are only two outcome = YES or NO
4) The probability of each outcome remains constant from trial to trial = 50 - 50

the answer is D on edge

Step-by-step explanation:

The Museum of Science in Boston has an exhibit in which metal balls drop down a chute, bounce around, and wind up in one of 21 bins. After 1000 balls have dropped, the heights within the bins clearly follow a bell-shaped curve. If the standard deviation is 3 bins, approximately how many balls are in bins 1 through 7?A) 100
B) 160
C) 50
C) 330

Answers

if you have 21 bins then the 'middle bin' is bin 11 (starting at 1)So the 'mean' of this distribution is 11.The SD is 3so using the above calculator (or your own tables ) you get that the probability of a ball being in bin 7 or less is .091

1. What is the coefficient of x in the division (18x^3 + 12x^2 – 3x) / 6x^2?A) 3
B) 2
C) -0.5
D) -3

Answers

well since we're dealing with the co-efficient of x, then we just have to talk about 18x^3 and divide it by 6x^2 and we get 3x. so the co-eff. is 3 so (A)
