Answer:
D
Step-by-step explanation:
Let x = total number of basketball games that was played by the team this season.
Alon started in 60% of his team’s basketball games this season. This means that he started in a total number of 60 percent of x basketball games this season.
60% of x basketball games this season = 60/100 × x
= 0.6×x = 0.6x
From the information given, Alon started a total of 12 basketball games this season. Therefore,
0.6x = 12
x = 12/0.6 = 20
Answer:
x=10
Step-by-step explanation:
Answer: y - x = 1
Step-by-step explanation: Note : for two lines to be parallel, then they have the same slope.
i.e the slope is 1
Using y - y1 = m ( x-x1) to find the equation of the line
⇒ y - 2 = 1 (x - 1)
y - 2 = x - 1
y - x = -1 +2
y - x = 1
it could also be written in slope intercept form as y = x + 1
Answer:
14.6%
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ (1−p)ⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
and p is the probability of success.
Here, n = 10, r = 4, and p = 1/4.
P = ₁₀C₄ (1/4)⁴ (1−1/4)¹⁰⁻⁴
P = 210 (1/4)⁴ (3/4)⁶
P ≈ 0.146
There is an approximate 14.6% probability that exactly 4 of the 10 adults are on a diet.
