Answer:
So the answer for this case would be n=30 rounded up to the nearest integer
Step-by-step explanation:
Information given
the margin of error desired
standard deviation from previous studies
The margin of error is given by this formula:
(a)
And on this case we have that ME =2 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 99% of confidence interval now can be founded using the normal distribution. The significance level is 
and the critical value would be 
, replacing into formula (b) we got:
So the answer for this case would be n=30 rounded up to the nearest integer
3952/13 is 304 pounds at the cost of 13 dollars each fish is 152 pounds
Answer:
<2.1130913087, 4.53153893518>; <−3.03108891325, −1.75>; <−0.91799760455, 2.78153893518>
Step-by-step explanation:
Bruce's vector is <5cos(90-25), 5sin(90-25)> = <5cos(65), 5sin(65)> ≈ <2.1130913087, 4.53153893518>
The wind's vector is <3.5cos(270-60), 3.5sin(270-60)> = <3.5cos(210), 3.5sin(210)> ≈ <−3.03108891325, −1.75>
You add them together to find his actual motion:
<−0.91799760455, 2.78153893518>
