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

Answer:
- Yes, the ball reaches the height of 64 ft
Step-by-step explanation:
<u>Given function</u>
<u>The maximum value is at vertex and the x-value of the vertex is:</u>
<u>Finding the maximum height the ball can reach:</u>
- h(2) = -16(2²) + 64(2) = -64 + 128 = 64
The answer is yes
