Answer:
(19229.11 ,20770.89)
Step-by-step explanation:
We are given the following information:
Sample size, n = 17
Sample mean = 20,000 pounds
Sample standard deviation = 1,500 pounds
Confidence level = 95%
Significance level = 5% = 0.05
95% Confidence interval:
Putting the values, we get,
To have a weight of 2.21N., the ball's mass is (2.21/9.8) = .226kg.
<span>a) d = 1/2 (vt), = 1/2 (18 x .17), = 1.53m. </span>
<span>b) Acceleration of the ball = (v/t), = 18/.17, = 105.88m/sec^2. </span>
<span>f = (ma), = .226 x 105.88, = 23.92N. </span>
Answer:

Step-by-step explanation:
3(12)=2(y-1)
36=2y-2
36+2=2y
38=2y(<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>two</em><em>)</em>
y=19
-4fx + -8f - 5
