Answer:
120ft/sec
Step-by-step explanation:
Assuming that there is no acceleration, divide the amount of feet (720) with the time (6 seconds):
720 ft/6 sec = 120 ft/1 sec
For every second, the skydiver drops 120 ft.
120ft/sec.

$189
If the discounted price is $210, and his friend gets a 10% discount on that price, you can divide 210/10 and get 21.
Rocco's friend gets a $21 discount on the $210 irons, so therefore he will be paying $189
Answer:
The calculated value Z = 1.3114 < 2.576 at 0.01 level of significance
null hypothesis is accepted
The evidence that less than 4% of the company’s widgets are defective
Step-by-step explanation:
<u><em>Step(i):</em></u>-
<em>Given Population proportion </em>
<em> P = 4% = 0.04</em>
<em>Given sample proportion </em>
![p = \frac{6}{250} = 0.024](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7B6%7D%7B250%7D%20%3D%200.024)
<u><em>Null hypothesis </em></u>:- P < 0.04
<em>Alternative Hypothesis : P ≠ 0.04</em>
<u><em>Step(ii):</em></u>-
Test statistic
![Z = \frac{p-P}{\sqrt{\frac{PQ}{n} } }](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7Bp-P%7D%7B%5Csqrt%7B%5Cfrac%7BPQ%7D%7Bn%7D%20%7D%20%7D)
![Z = \frac{0.024-0.04}{\sqrt{\frac{0.04 X 0.96}{250} } }](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B0.024-0.04%7D%7B%5Csqrt%7B%5Cfrac%7B0.04%20X%200.96%7D%7B250%7D%20%7D%20%7D)
Z = - 1.3114
|Z| = | - 1.3114|
The tabulated value Z = 2.576
The calculated value Z = 1.3114 < 2.576 at 0.01 level of significance
null hypothesis is accepted
The evidence that less than 4% of the company’s widgets are defective
Answer:
1/8 of a cup.
Step-by-step explanation:
That would be 1/6 of 3/4
= 1/6 * 3/4
= 1*3 / (6*4)
= 3/24
= 1/8.
