Answer:
x=6
Step-by-step explanation:
Start by converting 300 feet to miles and 2.92 seconds to hours.
300 feet 1 mile
----------- x -------------- = ?
1 5280 feet
2.92 sec 1 hr
----------------- * ---------------- = ?
1 3600 sec
Reduce each of the above fractions. Then convert 300 feet
-------------- to the
2.92 sec
equivalent speed / rate in mph using the converstion factors you derived earlier.
Area is length times width [A=(L)(W)], if we know that the area of the card is 3/10 and the length is 4/5 we can set up the equation 3/10=(4/5)(W) where W is width. Solve for W by deciding both sides by 4/5 and we get that W=3/8. To find the perimeter of the card were have to add up all the sides of the card so 3/8+3/8+4/5+4/5 which equals 47/20
Answer:
<u>The correct answer is B. μ = US$87.50 and σ = US$6.50</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of baskets of apples picked each day by Parker = A
Mean of A = 4.5 baskets
Standard deviation = 1.3 baskets
Daily payment received by Parker = US$ 65 + US$ 5 per basket
2. What are the mean μ and standard deviation σ of Parker’s daily pay?
Let's find out the mean and standard deviation of Parker's daily pay:
Daily payment received by Parker = US$ 65 + US$ 5 per basket
Daily payment mean received by Parker = 65 + 5 * 4.5
Daily payment mean received by Parker = 87.5
Standard deviation in US$ = 1.3 * 5
Standard deviation in US$ = 6.5
<u>The correct answer is B. μ = US$87.50 and σ = US$6.50</u>
Slope is 2 and y-intercept is 9
