Step-by-step explanation:
f(x) = 3x + 2
g(x) = 4x
= f(x) + g(x)
= 3x + 2 + 4x
= (3 + 4)x + 2
= 7x + 2
(f+g)(x) = 7x + 2

Step-by-step explanation:
If you would like to solve 26/57 = 849/5x, you can do this using the following steps:
<span>26/57 = 849/5x /*(5x)
</span>26/57 * (5x) = 849 /*57
26 * 5x = 849 * 57 /26
5x = 48393/26 /5
x = <span>48393/(26*5)
x = 372.25
The correct result would be </span><span>372.25.</span><span>
</span>
Answer:
2/9
Step-by-step explanation:
given that Tyler selects one card from the three(4,5, and a King), and rolls a number cube.
We find that A the event of selecting one card and B getting a number on rolling a number cube are independent events.
No of cards = 3
Prob of selecting 5 from 3 cards = 
When rolling a number cube (assuming fair) there is equally likely for all numbers to appear from 1 to 6
Prob of getting 5 =
Prob of getting less than 5 =
Since these two events are independent,
the probability that she selects the 5, and rolls a number less than 5
= Product of probabilities
= *

Answer:
3.188
Step-by-step explanation:
Given that :
Sample data: 26.5, 28, 30.2, 29.6, 32.3, 24.7
Sample standard deviation (s) = 2.728
Mean (mu) = 25
Tstatistic formula :
(x - mu) / (s/sqrt(n))
n = sample size = 6 ; s = 2.728 ; mu = 25
Sample mean (x) = (26.5 + 28 + 30.2 + 29.6 + 32.3 + 24.7) / 6
Sample mean (x) = 171.3 / 6 = 28.55
Tstatistic = (28.55 - 25) / (2.728 / sqrt(6))
Tstatistic = 3.55 / 1.1137013
Tstatistic = 3.1875692
