So for this, we will be forming the equation
, and we will be solving for x. (3.25=325%)
For this equation, all you have to do is divide each side by 3.25, and your answer is gonna be
gallons.
All the angles inside a triangle add up to 180°.
(2x + 15) + (5x + 5) + x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20
the question is asking what angle B is,
B = 2(20) + 15
B = 40 + 15
B = 55°
Answer:
Step-by-step explanation:
First you will need to change both of the numbers into improper fractions:
56/1 ÷ 7/2
Then do keep change flip. What that means is keep the first fraction the same, change the division symbol into a multiplication symbol, and flip the second fraction:
56/1 x 2/7
Then just multiply the two numerators by each other and the two denominators by each other:
56 x 2 = 112
7 x 1 = 7
112/7 would be the answer.
This is a binomial distribution where 80% of flights arrive on time (p = 0.8) and 20% do not (q = 1 - 0.8 = 0.2). Then the probability that exactly 2 flights arrive late follows the formula:
(nCr)(p^r)(q^(n-r)), where n = 16 (total # of flights), r = 14 (flights that arrive on time)
(16C14)(0.8^14)(0.2^2) = 0.2111
