Thirty people are eligible to win cash prizes. The number of each cash award prize is shown in the table. Prizes will be given out randomly one at a time. What is the probability of the first person winning the $50 prize?

Answers

Answer:

0.1667

Step-by-step explanation:

Given that the Total number of people who are eligible to win cash prizes is 30.From the given table we notice that 5 people win $50 cash prize.

The probability of the first person winning the $50 prize is therefore :

$p=(Number \ who \ win \ \%50)/(Total \ no \ of \ people)\n\n=5/30\n\n=(1)/(6)=0.1667$

Hence the probability of the first person winning the $50 prize is 0.1667

A fence is shown on a blueprint and has a sides of leg the 17cm,18cm,18cm and 19cm.If themail scale on the blueprintis2cm:7cm,what is the total length of the fence?please tell me how did you get it.

Answers

ok so 2cm on the blueprint is actually 7cm in real life
2:7=1:3.5
for every cm on the map, it is 3.5 times that in real life

so total legnths
17 times 3.5+18 times 3.5+18 times 3.5+19 times 3.5=
59.5+63+63+66.5=
252

answer is 252cm

The answer is 252 cm. You divide each number by two and then multiply what ever that is by 7. ( since the ratio is 2:7)

A storage closet holds twelve boxes stacked upon each other, with each box being 10 inches high. How many feet are there between the top of the third box and the bottom of the tenth box?

Answers

Answer:5

Step-by-step explanation:there are 6 boxes between the top of the 3rd box and the bottom of the 10th box.

Since each box is 10 inches tall, the length of the 6 boxes sum up to 60 inches.

and since 12 inches =1 feet,

Then 60 inches = 5 feet

How to solve

Let "y" = the unknown number of feet's

12 inches = 1 feet

60 inches = y

Cross multiply

> 12×y =60×1

> 12y =60

Divide both sides by 12 since you want the value of "y".

> 12y÷12=60÷12

So 12 cancels out leaving the final answer to be:

> y=5

Answer:

There are 5 feet between the top of the third box and the bottom of the tenth box.

Step-by-step explanation:

We just have to count how many boxes is between the top of the third one and the bottom of the tenth box, then we transform from inches to feet.

So, the problem says "from the top of the third box" this means that the inches that matters is form the fourth box. "the bottom of the tenth box" means that it's until the ninth box. In total, there are 6 boxes. If each box is 10 inches high, the total distance would be 6(10 inches) = 60 inches.

Now we have the total distance, we transform it to feet. We know that one feet is 12 inches, using the rule of three we have:

$60in(1ft)/(12in)=5ft$
