Answer: a
Step-by-step explanation:
The total number of ways that these 4 numbers can be selected = 4! = 24
There is only 1 way to select them in ascending ( that is 1 2 3 and 4)
Required probability = 1/24
Answer:
Chelsea's guess of 85 plastic animals had a percent error of 2.29%.
Aziz's guess must have been 722
gumballs or 798
gumballs since his guess had a percent error of 5%.
<u>Step-by-step explanation:</u>
Number of plastic animals in a jar = 87
Chelsea's guess of number of animals = 85
Difference = 87 - 85
Hence, error percentage of Chelsea's guess = 2/87 * 100
= 2.29%
Number of gumballs = 760
Error percentage = 5%
Difference between number of gumballs and Aziz's guess = 760 * 0.05
= 38
Hence, Aziz's guess for number of gumballs = 760-38 (or) 760+38
= 722 (or) 798
Answer: 23/45
step-by-step explanation:
write out your equation equal to x
x = 0.51 with a repeating 1
count the repeating decimal (1) and multiply each sides of the equation by 10^1
10x = 5.11 with a repeating 1
9x = 4.6 subtract the first equation from the second
solve for x
x = 4.6/9
eliminate the 1 decimals by multiplying the numerator and denominator by 10^1
4.6/9 • 10/10 = 46/90
find the greatest common factor
46/2 / 90/2 = 23/45
the fraction is already simplified at 23/45
