1.) 3 (3t + s)
distribute
9t + 3s
plug in the variables
9 ( 12 ) + 3 ( 9 )
108 + 27
135
2.) 2s - t
plug in the variables
2 ( 9 ) - 12
18 - 12
6
I hope this helped and i sincerely hope that this was the brainliest answer!
have a nice day
A: (x^a) / (x^a) = x^(a - a) = x^0
B: Anything divided by itself is 1, so x^a / x^a = 1.
C: If x^a / x^a = x^0 from Part A and x^a / x^a = 1 from Part B, then x^0 = 1.
Reflect: 1. To complete Part A, we used the quotient rule for exponents.
Hope this helps!
Answer:
Mean= 554.4
Standard deviation= 82
Step by step Explanation:
The question want us to calculate a) mean b) standard deviation, while we were given the probability mass function of random variables.
The percentage were of the carbon dioxide were given below;
6% of the trees in a minimal growth condition at 340 = 0.06
13% at 430 ppm = 0.13
46% at 560 ppm = 0.46
35% at 630 ppm= 0.35

48/6 = 8
each bead weighs 8 grams.
72/8 = 9
9 beads weigh 72 grams.
Answer:
<em>B. 25,636 feet</em>
Step-by-step explanation:
sin(55) = h/x
h = 21,000
sin(55) = 21,000/x
x = 21,000/sin(55)
x = 25636.27 ≈ 25,636 feet
Hope this helped! :)
