Answer:
u+2b=22
Unicycles have one wheel and bicycles have two, so the coefficient of 2 should go before the variable representing each bike.
It should equal 22 because 15 represents the total number of seats and not wheels.
Step-by-step explanation:
The solution for this problem is:It's given that the heights are normally distributed.
5 feet 7 inches = (5*12 +7) inches = (60+7) inches = 67 inches.
The z-score is (67 - 69.1)/(2.65) = -1.136. The probability is 0.127978 or 12.8%, making probability of a height over 67 inches
Answer:
1 gallon = 16 cup
Step-by-step explanation:
Gallon is a larger measurement unit than cup.
The answer is 180 degrees. The rotation that maps one side
to an adjacent side is 360°/6 = 60°. This is the least rotation that plots
the regular hexagon to the aforementioned. In the least whole number of these
minimum rotations,
such as three 60° rotations to make 180°, will retain
the hexagon identical.
Answer:
- 1/4
Step-by-step explanation:
Where you see X, substitute with 1/3
Solve the power/exponent first:
6(1/3) = 2
That is ; - 4(1/4)^2
Solve the parenthesis:
(1/4)^2 = 1/16
-4(1/16)
= - 1/4
