Answer:
Coca cola bottles = 6
Milk bottles = 14
Jellybeans = 10
Step-by-step explanation:
We are given that a bag of sweets contains coca cola bottles, milk bottles and jellybeans.
The ratio of these sweet bottles is given as,
3:7:5
It is known that there are 6 coca cola bottles.
We are asked to find the quantity of milk bottles and jellybeans.
Coca cola bottles:
Since the ration is 3:7:5
3 parts of coca cola bottle = 6
1 part of coca cola bottle = 6/3 = 2
Milk bottles:
So 7 parts of milk bottle = 7*2 = 14
Jellybeans:
So 5 parts of milk bottle = 5*2 = 10
Therefore,
Coca cola bottles = 6
Milk bottles = 14
Jellybeans = 10
Verification:
6:14:10
Simply the ratio by dividing it with 2
3:7:5
Which reduces to the given ratio hence results are correct.

Answer:
15/4
Step-by-step explanation:
2 1/2 x 1 1/2
First, make them both improper fractions to make them easier to multiply
5/2 x 3/2
Multiply their numerators together to get the numerator and multiply their denominators together to get the denominator.
5 x 3 = 15
2 x 2 = 4
5/2 x 3/2 = 15/4
Answer:
The probability that there will be repair exactly 3 toaster is 0.0574.
Step-by-step explanation:
Binomial Distribution:
A discrete random variable X having the set {0,1,2,3......,n} as the spectrum, is said have a binomial distribution with parameter n= number of trials and p=probability of number of success on an individual trial, if the p.m.f (probability mass function) of X given by,
x=0,1,2,......,n
=0 elsewhere
where 0<p<1 and n is a positive integer.
Total number of toaster in cartons(n) = 10.
Probability of number of success on an individual trial p= 10% = 0.10
=0.0574
The probability that there will be repair exactly 3 toaster is 0.0574.
Answer:
Step-by-step explanation:
I've attached a pic, I used y for sin(theta) and x for cos(theta). Shows all steps. See image.
Step 1: use "factoring sum of cubes" to factor the numerator.
Step 2: in the trinomial, in the numerator, rearrange terms to use the sin^2 + cos^2 = 1 .
Step 3: cancel that factor with the denominator.
