Answer:

3.75

Step-by-step explanation:

I took a test and that was the answer

Harold ran 3.75 kilometers in 5 kilometers long race.

The mathematical operation of multiplication is arithmetic. Additionally, it involves repeating the same forms of statements.

Example: 2 + 3 signifies that 2 is multiplied by 3 or that 3 is multiplied by 2 times.

Given, a race is 5 kilometers long.

Harold ran 3/4 of the race.

To find the numbers of kilometers, Harold run

That means,

we multiply 3/4 to the total race's length.

Required length

= 5 x 3/4

= 15/4

= 3.75

Therefore, Harold ran 3.75 kilometers.

Answer:

The right answer is "z = 3.68".

Step-by-step explanation:

Given that,

p = 52%

or,

  = 0.52

n = 200

[tex]\hat{p}= \frac{130}{200}[/tex]

  [tex]= 0.65[/tex]

Now

The test statistic will be:

⇒  [tex]z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]

On substituting all the given values, we get

⇒     [tex]=\frac{0.65-0.52}{\sqrt{\frac{0.52(1-0.52)}{200} } }[/tex]

⇒      [tex]=\frac{0.13}\sqrt{{\frac{0.52\times 0.48}{200} }}[/tex]

D) 205

Step-by-step explanation:

Given : Cost = 83 - 2 (time taken) + 6 (materials) + 1.1 (marketing cost)

Relationship Equation : y = 83- 2x1+ 6x2 + 1.1x3

Given, time (x1) = 5 , materials (x2) = 4 , marketing cost (x3) = 100

So, putting values, Cost : y = 83 - 2 (5) + 6 (4) + 1.1 (100)

= 83 - 10 + 24 + 110 = 207  

The closest to this calculated estimated figure ie 207, is 205.

I calculated it logically

20×36= 720

5×15= 75

75+720= 795

the correct answer is 795 ><

75 as a fraction of 125 would be 75/125

Now Lets simplify

75/25=3

125/25=5

We get 3/5

We can not reduce 3/5 anymore, so the answer is 3/5

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25. 75 is 3/5 fraction of 125.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Step-by-step explanation:

The volume of a rectangular prism is given by [tex]V=l\cdot w\cdot h[/tex].

Thus, we have the equation:

[tex]V=5\cdot 4\cdot 6[/tex]

Solving, we get:

[tex]V=5\cdot 4\cdot 6=\boxed{120\:\mathrm{in^3}}[/tex].

Answer:

120

Step-by-step explanation:

length time width time height

6 times 4 times 5

would be you equation the 120 would be your volume  

The Equation to represent the "total-cost", "t", for purchasing "5 hardcover books", 8 "paperback-books", and 6 music CDs during the sale is t = 4h + 6.4p + 6m - 1.

The cost of the hardcover-book is = $h,

The cost of the paperback-books is = $p,

The cost for one music-CD is = $m,

In the sale, the price of each book is reduced by 20%, and

The price of music-CD is reduced by $1,

So, the cost of 5 hardcover books during the sale is:

⇒ 5h - 0.2(5h) = 4h     ...because 20% = 0.2;

and the cost of 8 paperback books during the sale is:

⇒ 8p - 0.2(8p) = 6.4p,

The cost of 6 music CDs during the sale is ⇒ 6m - 1;

So, the total cost, "t", for buying 5 hardcover books, 8 paperback books, and 6 music CDs during the sale is:

⇒ t = 4h + 6.4p + 6m - 1,

Therefore, the required equation of "total-cost" is t = 4h + 6.4p + 6m - 1.

A summation, also called a sum, is the result of arithmetically adding numbers or quantities. 155 is the answer for 5 times the sum of 24 and 7.

A summation, also called a sum, is the result of arithmetically adding numbers or quantities.

Given,

5 times the sum of 24 and 7

Sum is nothing but addition.

When we see the word sum it means we are adding some value with other factor. In the given problem 24 and 7 are added.

Times means multiplication.

We have to convert 5 times the sum of 24 and 7 to expression.

When we see times, it means product or we are multiplying a number with the other number. Here with 5 we are multiplying the sum of 24 and 7.

5×(24+7)

Firstly we calculate value in parenthesis.

twenty four plus seven is thirty one.

5×31

The product of 5 and 31 is 155.

Answer: Width = 5.5ft

Length = 18ft

Step-by-step explanation:

Let the width of the rectangle be x

Since the length of the rectangle is 7 ft more than twice the width. This mean that the length will be:

= (2 × x) + 7 = 2x + 7.

Therefore, length × width = area

x × (2x + 7) = 99

2x² + 7x = 99

2x² + 7x - 99 = 0

2x² + 18x - 11x - 99 = 0

2x(x + 9) - 11(x + 9) = 0

(2x - 11) = 0

2x = 0 + 11

2x = 11

x = 11/2

x = 5.5

The width is 5.5ft

Length = 2x + 7 = 2(5.5) + 7 = 11+7 = 18ft

Answer:

A is the answer it sounds more likely

For given data, being a girl and playing a sport are independent events as P(girl) = P(girl plays a sport) = 0.4.

"If A and B are independent events then, P(A∩B) = P(A).P(B)"

"It is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.

For given question,

We have been given a table that shows the results broken down by gender.

             Play sports         Do not play sports       Total

Boy            105                            75                        180

Girl             70                             50                        120

Total          175                            125                       300

Using the definition of probability:

⇒ P(girl)  = Number of girls/ Number of students

⇒ P(girl) = 120/300

⇒ P(girl) = 0.4                     ....................(1)

Now we find the probability of girls that play a sport.

Using the definition of probability:

P(girl plays a sport)

= Number of girls who plays a sport/ number of students who plays a sport

= 70/ 175

= 0.4                                    ......................(2)

From (1) and (2),

P(girl) = P(girl plays a sport)

Thus, being a girl and playing a sport are Independent events.
