g At a certain gas station, 30% of all customers use the restroom. What is the probability that, out of the next 10 customers, (
Kruka [31]

Answer:

P(x=4) = 0.200

Step-by-step explanation:

Given

n=10 --- selected customers

x = 4 --- those that are expected to use the restroom

p =30\% = 0.30 --- proportion that uses the restroom

Required

P(x = 4)

The question illustrates binomial probability and the formula is:

P(x) = ^nC_x * p^x * (1 - p)^{n - x}

So, we have:

P(x=4) = ^{10}C_4 * (0.30)^4 * (1 - 0.30)^{10 - 4}

P(x=4) = ^{10}C_4 * (0.30)^4 * (0.70)^6

P(x=4) = 210* (0.30)^4 * (0.70)^6

P(x=4) = 0.200

How can you identify unit rate from a table, equation and graph ​
Zina [86]

Answer:

hiiii

Step-by-step explanation:

To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate.

(Table)

In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour. ( equation)

To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate. So in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the unit rate. ( Graph)

Estimate the difference 8 7/12 - 4 7/8 - 4/10
Gnesinka [82]
When you are told to estimate, you should be able to do the problem in your head.
8 7/12 is close to 8 1/2
4 7/8 is very nearly 5
4/10 is very nearly 1/2

8 1/2 - 5 - 1/2 First of all you can take the 1/2 away from 8 1/2
8 1/2 - 1/2 = 8
Now take away the 5


8 - 5 = 3

So the answer is very nearly
3 <<<<< answer.

Just for fun, I'll get the exact answer. Don't hand this one  in. It is 3 37/120
You learn to estimate because you are trying to guess whether or not you've entered everything correctly into your calculator. When writing a test, this is a very handy skill to have developed.

One number is one third of another number. The sum of both numbers is 16. Find the numbers.
solong [7]

Answer: 4 and 12

Step-by-step explanation:

Let x be the "another number"

Therefore, "one number" is 1/3x

1/3 x + x = 4/3 x

4/3 x = 16

1/3 x = 4

x = 12

Therefore, the numbers are 4 and 12.
