Given:
Actual: 9.0 lbs with standard deviation of 0.35 lbs
sample: 8.2 lbs
standard deviation means that the fish caught should be within the range of 8.65 and 9.35
9.00 + 0.35 = 9.35 lbs
9.00 - 0.35 = 8.65 lbs
The sample that had an average weight of 8.2 lbs is not a representative of the population because its weight goes beyond the standard deviation.
Answer:

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>
Answer:
Step-by-step explanation:
x= money earned per hour working as a cashier.
y=money earned per hour working delivering newspapers.
We propose the following system of equations:
5x + 4y =77
6x + 3y=78
We solve the system by reduction method:
-6*(5x+4y=77) ⇒ -30x-24y=-462
5*(6x+3y=78)⇒ 30x+15y=390
---------------------------
-9y=-72 ⇒ y=-72 /-9=8
Now, we get the value of "x" replacing the value of "y" by "8" in any part of the equation above.
5x + 4(8)=77
5x+32=77
5x=77-32
5x=45
x=45/5=9
therefore;
money earned per hour working as a cashier= $9/ hour
money earned per hour working delivering newspapers=$8/hour
It would be
.888,7/10,3/5,.27
what you would do is convert 7/10 and 3/5 into a decimal to see what order you would place them and 7/10 as a decimal is .7 and 3/5 to a decimal is .6 so .888 is greater then it will be 7/10 then 3/5 then .27
