Answer:
10 quarters
x=10
Step-by-step explanation:
25 pennies equals to .25 ⊄
6 nickels equals to .30⊄
2 dimes equals to .20⊄
Add it up: 25+30+20=75⊄
You will then subtract .75 from our total:
3.25-.75=2.50
You need 2.50 in quarters; remember .50 for two quarters and 1.00 for four.
Eight quarters will equal 2.00
and two quarters equals 50.
Add it up, 10 for 2.50.
You will have 10 quarters.
X=10
Answer: X can not be 11 or higher, so that means this problem will be 10 or lower. There for the value of X=6
Step-by-step explanation:
So, you have 3/4x + 5/8 = 4x. We can do this in two ways. Since fractions are harder to deal with, we can turn the fractions into whole numbers.
First we need to find the LCD (Least Common Denominator) between 4 and 8, which is 8. So multiply the 3/4x by 2/2, which gives you an equivalent fraction of 6/8x.
So now we have 6/8x + 5/8 = 4x. Now multiply both sides by 8, to get rid of the denominators of the fractions. That gives us 6x + 5 = 32x. Now use the subtraction property of equality to subtract 6x from both sides giving us 5 = 26x.
Now you can use the division property of equality to divide 26 on both sides, which gives us x = 5/26.
Hope this helps. :D Feel free to ask any other questions, and if you have any questions about my explanation, don't hesitate to ask.
Answer:
0.6988
Step-by-step explanation:
Given that the number of people who use the ATM at night outside your local bank branch can be modeled as a Poisson distribution.
Let X be the number of customers arriving between 10 and 11 am.
X is Poisson with mean= 1.2
Required probability
= the probability that in the hour between 10 and 11 PM at least one customer arrives
= P(X≥1)
=1-P(X=0)
=1-0.3012
= 0.6988
The answer is 100 because 128 is closest to 100. in order for it to be 200, it has to be over 150
