Answer:
So scientific notation would be 5 x 10 ^7, and standard would be 50,000,000
Step-by-step explanation:
The 7 means you move the decimal to the right 7 times, meaning you add 7 zeros.
Answer:
28 1/24 pounds
Step-by-step explanation:
Collected recyclables:
Rushdi = 7 5/8 pounds
Lydia = 9 2/3 pounds
Latrelle = 10 3/4 pounds
Total amount of recyclables collected :
(7 5/8 + 9 2/3 + 10 3/4) pounds
(61/8 + 29/3 + 43/4) pounds
L. C. M = 24
(183 + 232 + 258) / 24
673 / 24
= 28 1/24 pounds of recyclables.
She had a rate of return of 21.5%.
Her total cost to buy the shares was:
500 x 8.24 + 20 = 4140
When she sold the stocks, she made:
500 x 10.10 - 20 =5030
The difference of those two amounts is $890.
Converting it to a percent gives:
890 / 4140 x 100 = 21.5%
So we know that there's 12 inches in 1 foot. So we just need to do multiplication here
14 x 12 = 168 inches
Answer:
0.945200708
Step-by-step explanation:
In this question, we are asked to calculate the probability that a person selected at random would live less than 65.
To solve this problem, what we need to do is to first calculate the z-score.
Mathematically, z = (x-mean)/standard deviation
According to the question, the mean is 53 years and the standard deviation is 7.5
Substituting these values in the z-score equation:
Z-score = (65-53)/7.5 = 12/7.5 = 1.6
We proceed to use the z-score table to obtain the probability. Using the table, z score of 1.6 corresponds to a probability of
0.945200708
