Take $1.50 from $2.50 and get $1.00 then divide it by 4 since that is the time period.

$1.00/4= $0.25

Therefore making your answer B.

$1.00/4= $0.25

Therefore making your answer B.

Eight minus three is five so 5/8.

**Answer:**

The probability is 0.152

**Step-by-step explanation:**

We know that in this town 39% of all voters are Democrats. Therefore, the probability of a randomly selected voter being a Democrat is

The experiment of randomly select voters for a survey is called a Bernoulli experiment (under some suppositions). We suppose that exist independence in this randomly selection of voters. We also suppose that there are only two possibilities for the voter : It is Democrat or not.

Now the variable X : ''The randomly selected voter for a survey is Democrat'' is a Binomial random variable.

X ~ Bi (n,p)

The probability function for the BInomial random variable X is :

Where ''n'' is the number of Bernoulli experiments (In this case n = 2 because we randomly selected two voters)

P(X=x) is the probability of the variable X to assumes the value x

(nCx) is the combinatorial number define as

p = 0.39 in this exercise.

We are looking for P(X=2) ⇒

If we round to the nearest thousandth the probability is 0.152

You can cross multiply to find the answer. Start by setting up your equation:

45/30 = 60/x (30 represents half an hour)

Next, cross multiply, 45 times x, and 60 times 30:

45x = 1800 you must isolate the "x" value by using the opposite operation it is involved in. Here we have 45x (x is multiplied to 45) so we must divide 45, which will cancel itself out, leaving us with "x."

What you do on one side of the equation, you must do on the other, so divide 1800 by 45 as well, which will leave you with 40.

Working it out on paper, your equation should now look like this: x=40, which represents the amount of time it will take to fill a 60 gallon tube.

Answer: It will take**40 minutes **to fill a 60 gallon tube.

X = multiplication

h = height

r^2 = radius squared

Formula of a cylinder: Pi x r^2 x height

So, if 176 = 3.14... times 4^2 times h

Then, 176 = 3.14 times 16h

Next, 176 = 50.24h

Finally, 3.5 = h

You can then check your work by plugging 3.5 back in for the missing height and round to the nearest tenth. :) The answer should come out the same if done correctly.

**Answer:**

$111 is earn by shoe salesman as commission .

Option (A) is correct .

**Step-by-step explanation:**

As given the statement in the question be as follow.

Shoes salesman sold 3 pairs of shoes for $70 each and 2 pairs of shoes for $80 each.

Thus

Total cost of the pair of shoes = 3 × 70 + 2 × 80

= 210 + 160

= $ 370

As given

shoe salesman earns a commission of 30% of all shoe sales made.

30% is written is decimal form

= 0.30

Commission earns = 0.30 × Total cost of the pair of shoes .

= 0.30 × 370

= $ 111

Therefore $111 is earn by shoe salesman as commission .

Option (A) is correct .
