Answer:
The answer is 14
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
Complete the multiplication and the equation becomes
The two fractions now have like denominators so you can add the numerators.

Answer:
C.
Step-by-step explanation:
Simply add the two functions.
5x³+2x²-7x+4
+ 3x-7
Everything with an exponent stays the same because there is nothing else with those exponents in the other function. So all you're doing is adding the -7x+4 and 3x -7.
-7x+3x = -4x
4 - 7 = -3
That leaves you with answer C:
5x³+2x²-4x-3
Answer:
[tex]C.(f+g)(x)=(5x^3+2x^2-4x-3)[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\f(x)=5x^3+2x^2-7x+4\\g(x)=3x-7\\Hence,\\(f+g)(x)\\=f(x)+g(x)\\Hence,\\f(x)+g(x)=(5x^3+2x^2-7x+4)+(3x-7),\\ f(x)+g(x)=(5x^3+2x^2-7x+3x+4-7) \\f(x)+g(x)=(5x^3+2x^2-4x-3)\\Hence,\\(f+g)(x)=(5x^3+2x^2-4x-3)[/tex]
9965 divided by 19.9 estimate
Answer: 500.7
500.75 = 500.7
Step-by-step explanation:
The estimated value is 500
What is estimation?Estimating in math is a way of approximately calculating an answer (getting a 'rough answer') or to check its accuracy (the 'right answer').
Given that, 9965 divided by 19.9 estimate
Let 9965 ≈ 9970
19.9 ≈ 20
9970 ÷ 20
9970 / 20
= 498.5
≈ 500
Hence, the estimated value is 500.

Question Help The mean finish time for a yearly amateur auto race was 185.64 minutes with a standard deviation of 0.314 minute. The winning car, driven by Sam, finished in 185.29 minutes. The previous year's race had a mean finishing time of 110.3 with a standard deviation of 0.129 minute. The winning car that year, driven by Rita, finished in 110.02 minutes. Find their respective z-scores. Who had the more convincing victory?
Answer:
Sam has the more convincing victory with a greater Zscore value
Step-by-step explanation:
Given that :
Year 1:
Mean finish time (m) = 185.64
Standard deviation (s) = 0.314
Sam's time (x1) = 185.29
Year 2:
Mean finish time (m) = 110.3
Standard deviation (s) = 0.129
Rita's time (x1) = 110.02
Zscore = (x - mean) / standard deviation
Sam's Zscore :
(185.29 - 185.64) / 0.314
= - 0.35 / 0.314
= −1.114649
= - 1.115
Rita's Zscore :
(110.02 - 110.3) / 0.129
= - 0.28 / 0.129
= −2.170542
= - 2.171
Sam has the more convincing victory with a greater Zscore value
