The probability P(E) is 13/15.

According to the statement

we have given that the S = {1, 3, 5, 7, 9}, E = {1, 5, 7}

And we have to find the probability P(E).

So, For this purpose

Recall the formula for the probability of an event E in case when all outcomes are equally likely:

P(E)= n(E) /n(S)

in which S is the sample space.

But we have the S = {1, 3, 5, 7, 9},

so, n(S) = Sum of all outcomes / number of outcomes

n(S) = 1+3+5+7+9 /5

n(S) = 25 /5

n(S) = 5 and

For n(E) = Sum of all outcomes / number of outcomes

n(E) = 1+5+7 /3

n(E) = 13 /3

n(E) = 13 /3

Substitute these values in the above written formula then

P(E)= n(E) /n(S)

P(E)=  (13/3)/ 5

P(E)= 13 /15

So, The probability P(E) is 13/15.

Jake has 56 cupcakes to put into some cake tins. he puts the same number of cupcakes into each tin. 5 tins contain 35 cupcakes i
stiks02 [169]
Let's first come up with an equation that we can use to solve this problem.

Total Cupcakes= Cupcakes in each tin • the number of tins.

We are given the total number, and we want to find the number of tins and number in each tin now. So our equation looks like this.

56= cupcakes per tin • # of tins.

If we know that in 5 tins there are 35 cupcakes, and each tin has the same number we can divide 35 by 5 to find out there are 7 cupcakes in each tin. Now we have more info for our equation.

56 = 7 • # of tins.
We can divide the total number by the number in each tin, 56/7= 8.

Your answer is 8 tins.

A water tank already contains 55 gallons of water when Baxter begins to fill it. Water flows into the tank at a rate of 8 gallon
Roman55 [17]

Answer: 8x+55=127

Step-by-step explanation: it would take 9 mins because there’s already 55 gallons of water in the tank so you subtract that from 127 which is 72 then you divide 72 by 8 and get 9

Divide a 5 1/4 inch line into three parts whose ratios are 1:2:3.
stich3 [128]
1:2:3...total is 6

1/6 of 5 1/4 = 1/6 * 21/4 = 21/24 = 7/8
2/6 of 5 1/4 = 2/6 * 21/4 = 42/24 = 1 3/4
3/6 of 5 1/4 = 3/6 * 21/4 = 63/24 =  2 5/8

7/8, 1 3/4, 2 5/8...total = 5 1/4 inches
