Answer:
Step-by-step explanation:
187 divided by 7 is 6.5
630 red marbles
420 yellow marbles
210 purple marbles
because 1260 x 1/2 = 630, 1260 x 1/3 = 420, 1260 x 1/6 = 210
V= 15 steps are down below
Answer:
the probability that the exceeded 65 = 0.3707
The average score of the 36 golfers exceeded 65
= 36 X 0.3707 = 13.3452
Step-by-step explanation:
<u>Step 1</u>:-
The average score of all golfers for a particular course has a mean of 64 and a standard deviation of 3.
mean (μ) = 64
standard deviation (σ) =3
by using normal distribution
given (μ) = 64 and (σ) =3
i) when x =65
P( X≥ 65) = P(z≥0.33)
= 0.5 - A(z₁)
= 0.5 - 0.1293 (see normal table)
= 0.3707
The average score of the 36 golfers exceeded 65
= 36 X 0.3707 = 13.3452
Answer:
The two linear inequalities =
x + y ≤ 200
100x + 25y ≥ 3000
Step-by-step explanation:
The auditorium they're performing in can hold no more than 200 people.
This means the number of tickets that would be sold would be less than or equal to 200 people
The tickets are represented as:
Adult tickets = x
Children tickets = y
Hence
Inequality equation 1
= x + y ≤ 200
Gabby wants to make at least $3000 for new costumes.
These means greater than or equal to $3000
Adult tickets (x) are going to be sold for $100 per adult and children tickets (y) are going to be sold for $25 per child.
Inequality equation 2
= $100 × x + $25 × y ≥ $3000
= 100x + 25y ≥ 3000
