Answer:
40
Step-by-step explanation:
Find the smallest multiple number shared by the two numbers.
10: 10, 20, 30, 40
8: 8, 16, 24, 32, 40
40 is the smallest multiple shared by the two numbers, and is your answer.

Given:
4 large oranges @ 0.75 each
8 small oranges @ 0.50 each
total amount paid: 7.49 including sales tax.
4(0.75) = 3.00
8(0.50) = 4.00
3 + 4 = 7
7 + t = 7.49
t = 7.49 - 7
t = 0.49 total amount of tax paid.
0.49/7 = 0.07 sales tax rate
the sales tax rate is 7%
4(0.75) + 8(0.5) = 7
7 x 0.07 = 0.49
7 + 0.49 = 7.49
Answer:
0.4588
Step-by-step explanation:
When we have random sample, the z score formula we use is:
z = (x-μ)/σ/√n
where x is the raw score = 14
μ is the population mean = 13.9
σ is the population standard deviation = 2.9
n is random number of samples = 9
z = 14 - 13.9/2.9/√9
z = 0.1/2.9/3
z = 0.10345
Probability value from Z-Table:
P(x<14) = 0.5412
P(x>14) = 1 - P(x<14) = 0.4588
The probability that their mean life will be longer than 14 years is 0.4588
