Ivan has $8.75 in nickels and quarters in his desk drawer. The number of nickels is twice the number of quarters. How many coins of each type does he have?

Answers

Answer 1

Answer:

25 quarters50 nickels

Step-by-step explanation:

Since there are 2 nickels for every quarter, we can group the coins into groups consisting of 1 quarter and 2 nickels. Such a group will be worth 35 cents. So, the number of groups in $8.75 is ...

  $8.75/$0.35 = 25

25 groups of coins will have ...

  25 quarters

  50 nickels

Martha earns $16.50 an hour for a regular 40 hour week. He overtime payo is 1.5 times her regular hourly rate. This past week Martha earned $948.75 in total pay. Approximately, how many hours of overtime did she work this past week? (Round you answer to the nearest hour. Just put the number, do not include the word hour) *​

Answers

Answer:

12

Step-by-step explanation:

Regular work week is 40 hours; at $16.50 per hour, that comes to $660.

Subtracting $660 from the toal $948.75 yields $288.75, which represents her pay at the overtime rate of (1.5)($16.50/hr), or $24.75/hour

Dividing $288.75 by this overtime rate of $24.75/hr yields 11.666 ...

We conclude that she worked approximately 12 hours overtime to end up

with $948.75 total pay.

One gym costs $24 per month and has a joining fee of $135. Another gym costs $39 per
month but does not have a joining fee. How many months would it take for each gym to
cost the same amount of money?

Answers

Answer:

It would take 1 month for the first gym (costs $24 per month) and 4 month for the second gym (costs $39 per month)

Step-by-step explanation:

If you add up $24 and $135 it equals 159. So for the first month you have to pay (in total) $159 dollars. So, if you want to get the same amount of money you have to multiply 39. To find out what number you need to multiply 39 with 4. Then you would have to add $3.

Archie is stranded in a war zone in the land of the Xhosas. His only chance of survival is to reach Sudland, which lies 100 miles away. There are just two routes to Sudland; one is through a desert, and the other is a long and perilous trek through the mountains. Both routes are terribly dangerous. In the past, 26% of all who tried to reach Sudland failed. Of all attempts to reach Sudland, 1 out of every 40 were by the desert route. Although it is the longer route, the mountains seem to provide more success: 75% of those who attempted to reach Sudland through the mountains were successful. To save time, Archie intends to go via the desert. What are his chances of making it through to Sudland

Answers

Answer:

The  chances of success for Archie is [tex]P(S|D) =  35\%[/tex]

Step-by-step explanation:

From the question we are told that

 The distance of Sudland from Xhosas is   d =  100 miles

  The probability  of failure is  [tex]P(F) = 0.26[/tex]

  The probability of choosing the desert route is   [tex]P(D) = \frac{1}{40} =  0.025[/tex]

The probability of reaching Sudland through the mountain is  [tex]P(S|M) =0.75[/tex]

Generally the probability of choosing the  mountains route is

         [tex]P(M) = 1 - P(D)[/tex]

           [tex]P(M) = 1 - 0.025[/tex]

             [tex]P(M) = 0.975[/tex]

Generally the probability of success is mathematically represented as

       [tex]P(S) =  1- P(F)[/tex]

         [tex]P(S) =  1- 0.26[/tex]

          [tex]P(S) =  0.74[/tex]

       

Generally the probability of success in reaching Sudland is also mathematically represented as

     [tex]P(S) =  P(S|M) * P(M) + P(S|D) * P(D)[/tex]

=>   [tex]P(S|D) =  \frac{P(S) - P(S|M) * P(M)}{P(D)}[/tex]

substituting values

=>  [tex]P(S|D) =  \frac{0.74 - 0.75 * 0.975}{0.025}[/tex]  

=>  [tex]P(S|D) = 0.35 [/tex]  

=>  [tex]P(S|D) =  35\%[/tex]

5*2 = 10                   distributive property

(15a + 10) = -65       the +10 goes to the other side as -10

by 1.5 hours, what would be the new mean and standard deviation? (2 points)

O 6,2.5

0 7.5,4

O 6,4

0 7.5, 2.5

Answers

Answer:

(7.5, 2.5)

Step-by-step explanation:

Given the following information ;

Mean hours (x) = 6

Standard deviation = 2.5 hours

If each time is increased by 1.5 hours, then the newly calculated mean will also increase by the same amount of time, that is 1.5 hours. This is because, since each individual item used in calculating the initial mean increased by the same amount, the average increase will be that same value (1.5 hours). Hence, the mean will increase by the same amount.

New mean = 6 hours + 1.5 hours = 7.5 hours

For the standard deviation ; which measures the variation of values from the mean, in this scenario, the standard deviation remains the same because the each value and the mean changed by equal amount, hence the bet change remains the same and so does the standard deviation.

This is the answer because:

You can use PEMDAS or GEMS to help you remember the order of operations.

PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

GEMS: Grouping (Parenthesis), Exponents, Multiplication and Division (whichever comes first from left to right), Addition and Subtraction (whichever comes first from left to right).

1) We have to use the order of operations in order to solve this.

2) First, we have to divide because it's the first thing there is, 28/4 = 7

3) Next, we have to multiply since we cannot subtract before multiplying because you have to follow the rules of Order of Operations. 2 x 3 = 6

4) Finally, 7 - 6 = 1
