Answer:
The height of the ball after 2 seconds = 96 feet.
Step-by-step explanation:
Given:
<em>The height of a golf ball hit with an initial velocity of 80 FPS is given by:</em>
<em></em>
<em>where represents height of the ball in feet and represents time in seconds.</em>
To find the height of the ball after 2 seconds.
Solution:
In order to find the height of the ball after 2 seconds, we plugin t=2 in the given function of height.
We have:
<em>At seconds</em>
Thus, height of the ball after 2 seconds = 96 feet.
Answer:
Greatest sack = 42
1 candy bar and 3 lollipops
<em></em>
Step-by-step explanation:
Represent Candy bars with C and Lollipops with L
Solving (a): Greatest number of treat sacks
To solve this, we simply calculate the GCF of C and L
Hence, the GCF is
Hence, greatest number of sack is 42
Solving (b): Number of treat in each sack.
To do this, we simply divide the number of C and L by the calculated GCF
For C:
For L:
<em>Hence, 1 candy bar and 3 lollipops</em>

Answer:
b) B and D and c) A and C
Step-by-step explanation:
The hypotheses would be:
(Right tailed test at 5% level)
Sample proportions are
Sample A B C D
Success 31 34 27 38
Proportion p 0.775 0.85 0.675 0.95
Std error
(sqrtpq/n) 0.066 0.056 0.074 0.034
p diff
p-0.75 0.025 0.10 - 0.075 0.20
Z stat
p diff/SE 0.0757 1.77 1.01 5.80
p value 0.469 0.038 0.156 0.000001
we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.
b) Only B and D provide against the null. Because p <0.05
c) A and C provide no evidence for the alternative because p >0.05
The y row changes by 3 each spot. The x row changed by 4 each spot. So the slope is 3/4x.
