You read 9.75 pages in your science book and 24.5 pages of a play for English class. It takes you 1.2 minutes to read each page of science and 0.8 of a minute to read each page of the play. How much time do you spend reading?

Answer:

1

Step-by-step explanation:

One year, the distribution of salaries for professional sports players had mean $1.6 million and standard deviation $0.8 million. Suppose a sample of 400 major league players was taken. Find the approximate probability that the average salary of the 400 players that year exceeded $1.1 million.

z = (x-μ)/σ/√n

where

x is the raw score

μ is the population mean

σ is the population standard deviation

n = random number of samples

Mean $1.6 million and Standard deviation $0.8 million.

z = (1100000- 1600000)/800000/√400

z = -500000/800000/20

z = -500000/40000

z = -12.5

Probability value from z score table is :

P(x ≤ Z) = P(x = 1100000) = P(z = 12.5)

= 0

P(x>Z) = 1 - P(x < Z)

= 1 - 0

= 1

The approximate probability that the average salary of the 400 players that year exceeded $1.1 million is 1

Answer:

Should be $368.94

please mark brainliest

The total cost of 118.25 gallons of gas is $368.94. Therefore, option A is the correct answer.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Todd drives 2,365 miles in a month and the average is 20 miles per gallon

Now, number of gallons =2,365/20

= 118.25 gallons

So, total cost = 118.25×3.12

= $368.94

Therefore, the total cost of gas is $368.94.

Answer:

The answer is -1008, it's in the comments

Answer:

B

Step-by-step explanation:

The figure is in quadrant 1. When you do a 180 degree rotation it will out the image diagonally across into quadrant 3. Next reflect across the y-axis to get it in quadrant 4.

A 180 rotation will always end up diagonally across regardless if it is counterclockwise or clockwise.

Answer:

A. Counterclockwise rotation around the origin by 180 degrees followed by reflection around the x-axis.

Step-by-step explanation:

180° would be turning it counterclockwise 2 times. Thus putting it on the points of figure P'Q'R'S'.

Reflecting it across the x-axis would be putting it in the same position as P'Q'R'S'.

This being said, either way you did it, as long as you did it one of the two ways it would become a copy of PQRS. The answer is A.

Hope this helped you. Let me know if I got it correct!

Answer:

x = 13 and x = 1

Step-by-step explanation:

(x-7)² = 36

simplify left side of equation

x² - 14x + 49 = 36

Our object now is to get every thing on the left side of the equal sign so we can factor. To do this, we subtract 36 from both sides

x² - 14x + 13 = 0

we then factor the left side of the equation

( x - 1 ) ( x - 13 ) = 0

we then set factors equal to 0 and solve both factors for x

x - 1 = 0

add 1 to both sides

x = 1

x - 13 = 0

add 13 to both sides

x = 13

The values of x are x = 13 and x = 1

Step-by-step explanation:

The solution is: It occurred 90 times does the digit 5 occur in all the numbers from 100-999 .

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2.

The nth term of AP : a_n = a + (n – 1) × d

here, we have,

Explanation:

Here, we want to know the number of times the digit occurs

We can solve this with arithemetic progression

The first term here is 105, while the last term is 995

However, the difference between each occurrence is 10

Thus, applying the formula:

T_n = a + (n-1) d

T_n is the last term which is 995

a is the first term which is 105

d is the common difference which is 10

n is the number of terms which we want to calculate

Substituting these values, we have it that:

995 = 105 + (n-1) 10

so, we get,

n = 900/10

  =90

Hence, It occurred 90 times does the digit 5 occur in all the numbers from 100-999 .

Answer:

The correct answer is 3/5

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since we are to show by Pythagoras that  the square will fit inside the circle without touching the edge of the circle , this means that we must find the value of the length of the diagonal of the square using Pythagoras.

For the square to fit in without touching the edge of the circle , this means that the diagonal of the square must be less than the diameter of the circle.

Length of the square is 5cm.

Recall Pythagoras theorem: it states that

the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides

=  +

= 25 + 25

= 50

Take the square root of both sides , that is

D =

D =  X  , since 50 = 25 x 2

D = 5

D ≈ 7.07
