Step-by-step explanation:
12.09 - 8.30 = 3.79
The reason why her answer was wrong is because when the '2' gets slashed into a '1' during carry over, it would have been 11 - 8 = 3 instead of a 4. (the 1st column)
The error that Juanita made is that she made a computational error when subtracting.
Answer:
x can be replaced by 8 and -8
Step-by-step explanation:
Given : 1: x = x:64
We have to find the value of x,
Consider 1: x = x:64
This is same as writing,
Taking square root both sides, we have,
We know
Thus, x has two values x = 8 and x = -8
Answer:
75 cent.
Step-by-step explanation:
It's 51 + 24 because it grows one centimeter every month.
51 + 24 = 75 cent.
Answer:
0.01
Step-by-step explanation:
Using the z score formula
z = (x-μ)/σ,
where x is the raw score = 135
μ is the population mean = 100
σ is the population standard deviation = 15
z = 135 - 100/15
z = 2.33333
P-value from Z-Table:
P(x<135) = 0.99018
P(x>135) = 1 - P(x<135)
P(x > 135) = 1 - 0.99018
= 0.0098153
Approximately to 2 decimal places
= 0.01
Therefore, the proportion of the population for the following IQ score of 135 is 0.01
