Answer:
x = 3, x = 0
Step-by-step explanation:
To solve these factored equations, just divide each part by zero and solve.
2x(x-3) = 0 → (x-3) = 0, and 2x = 0.
(x-3) = 0 → x - 3 + 3 = 0 + 3 → <u>x = 3.</u>
2x = 0 → 2x/2 = 0/2 → <u>x = 0.</u>
This equals the the area of white part / area of the entire dartboard
area of the entire board = pi * 6^2 = 36pi
area of white part = 36pi - 2^2*pi = 32pi
do required probability = 32pi / 36pi = 0.889 or 88.9 % (to nearest tenth)
or as a fraction it is 8/9
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>
Answer:
angle 2 is equal to angle 1 ... vertically opposite angles equal
therefore angle 2 and angle 3 are supplementary...co-interior angles supplementary
therefore m is parallel to n
