Answer:
9
Step-by-step explanation:
three more than the sum of (3,3)
lets first do the sum of (3,3)
3 + 3 = 6
now it's asking<em> three more than the sum of (3,3)</em>
three more than means we need to add 3 to 6
6 + 3 = 9

To solve this, plug 2b+1 in for a. :
4(2b+1)-5. Solve for b.
First use the distributive property:
8b+4-5=?
Combine like terms:
8b-1=?
Solve for b.
add 1 to both sides.
8b=1
Divide both sides by 8.
b=1/8
Answer:
0.57142
Step-by-step explanation:
A normal random variable with mean and standard deviation both equal to 10 degrees Celsius. What is the probability that the temperature at a randomly chosen time will be less than or equal to 59 degrees Fahrenheit?
We are told that the Mean and Standard deviation = 10°C
We convert to Fahrenheit
(10°C × 9/5) + 32 = 50°F
Hence, we solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 59 °F
μ is the population mean = 50 °F
σ is the population standard deviation = 50 °F
z = 59 - 50/50
z = 0.18
Probability value from Z-Table:
P(x ≤59) = 0.57142
The probability that the temperature at a randomly chosen time will be less than or equal to 59 degrees Fahrenheit
is 0.57142
Answer:
Step-by-step explanation:
Ello again!
Ok so you would turn the percent into a decimal again 8% ↠ 0.8
then you would multiply the decimal and money 90 × 0.8 = 72
Hope dis helped FAM
