Answer:
<u>The correct answer is A. 10 - 2</u>
Step-by-step explanation:
1. Let's make all the comparisons for the four alternatives:
A. 3 + 7 > 10 - 2 ⇒ 10 > 8, the comparison is correct because 10 is bigger than 8.
B. 3 + 7 > 9 + 4 ⇒ 10 > 13, the comparison is not correct because 10 is less than 13.
C. 3 + 7 > 7 + 3 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.
D. 3 + 7 > 8 + 2 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.
<u>The only correct comparison is A. 10 - 2.</u>
Answer:
Refer to the following information on full-term births in the United States over a given period of time.
Type of Birth Number of Births
Single birth 47,200,000
Twins 600,000
Triplets 3000
Quadruplets 200
Use this information to estimate the probabilities of the following events.
(a) A randomly selected pregnant woman who reaches full term delivers twins. (Give the answer to three significant figures.)
(b) A randomly selected pregnant woman who reaches full term delivers quadruplets. (Give the answer to three significant figures.)
(c) A randomly selected pregnant woman who reaches full term gives birth to more than a single child. (Give the answer to three significant figures
Answer:
width = 5k^2
length( 3k^2 +7k +4)
Step-by-step explanation:
15k^4 +35k^3 +20k^2
The width is the greatest common factor
We can factor 5k^2 out
5k^2( 3k^2 +7k +4)
The length is what is inside the parentheses
Answer:
x + y = 104
0.05x + 0.25y = 22
x = 20 niquels and y = 84 quarters
Step-by-step explanation:
Each niquel is $0.05, and each quarter is $0.25
So if we have x niquels and y quarters, we can set this system of equations:
x + y = 104 (eq1)
0.05x + 0.25y = 22 (eq2)
If we multiply the second equation by 4, and then subtract it from the first equation, we have:
(eq2)*4: 0.2x + y = 88
(eq1) - 4*(eq2): 0.8x = 16
x = 20
Now finding y with the first equation:
20 + y = 104
y = 84
