Problem 1

There are 23 women that drive out of 12+3+23+8+5+32 = 83 people total

Divide the two values: 23/83 = 0.28 approximately

This says about 28% of the total people are women who drive a car.

Answer:  0.28

===========================================================

Problem 2

The "given" is a very important keyword in probability. In this case, we're given that the employee takes the bus. That means we soly focus on the "bus" column only. Everything else is irrelevant. This is because we know 100% that whoever we selected takes the bus, and we've shrunk down the population just these employees.

We have 8 males who take the bus out of 12+8 = 20 people who take the bus. Therefore, 8/20 = 0.40 represents the relative frequency of males who take the bus out of all bus commuters. In other words, 40% of the bus riders are male.

Answer: 0.40

a rectangle with a length of 28 and perimeter of 64 what is the width and what is the area

Answers

A rectangle has 2 pairs of equal sides.
(28)(2)+ (2x) = 64
56 + 2x = 64
2x = 64 - 56
2x = 8
x = 4 [width]

Area = (lenght)(width) = (28)(4) = 112

write the equation polynomial whose graph contains the points (1,0),(-5,0),(-2,0),(-4,30)

Answers

Answer:

y = 3(x - 1)(x + 5)(x + 2)

Step-by-step explanation:

Given points:   (1, 0)   (-5, 0)   (-2, 0)   (-4, 30)

x-intercepts are when y = 0

Therefore, the x-intercepts are x = 1, x = -5 and x = -2

So (x - 1), (x + 5) and (x + 2) are all factors of the polynomial.

Therefore, the equation of the polynomial is:

y = a(x - 1)(x + 5)(x + 2)  where a is a constant to be found

To find the constant a, input the point (-4, 30) into the equation and solve:

⇒ a(-4 - 1)(-4 + 5)(-4 + 2) = 30

⇒ a(-5)(1)(-2) = 30

⇒ 10a = 30

⇒ a = 3

Therefore, the equation of the polynomial is:

y = 3(x - 1)(x + 5)(x + 2)

find a three-digit number, which is 5 times greater than the product of its digits

Answers

Answer:

175

Step-by-step explanation:

How would one find a three-digit number which is 5 times as large as the product of its digits?

100a + 10b +c = 5abc

This shows that c must be a multiple of 5. Since it is a digit, c=5 ( c=0 does not work ).

Then:

100a + 10b + 5 = 25ab

This again shows that 10b+5 is a multiple of 25.

By testing all the digits, b=2 or b=7.

If b=2, then

100a + 25 = 50a

which has the solution a= -1/2, not a digit.

if b=7

100a +75 = 175a

Now the solution is a=1, so finally the number is 175. Indeed, 175 = 5*1*7*5.

Which is an equation of the line that passes through the points (5,2) and (10,-3)?
A. y = x - 3
B. y = x - 8
C. y = -x + 7
D. y = -x + 12

Answers

Answer:

C

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (5, 2 ) and (x₂, y₂ ) = (10, - 3 )

m = [tex]\frac{-3-2}{10-5}[/tex] = [tex]\frac{-5}{5}[/tex] = - 1 , then

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (5, 2 ), then

2 = - 5 + c ⇒ c = 2 + 5 = 7

y = - x + 7 ← equation of line

The answer is C

You get this by first finding the slope between the two points
Y2 - Y1
X2 - X1
It gives you 5/-5 which is -1
So you can narrow it down to options C and D

Now you can just substitute into both equations

2 = -(5) + 7
2 = 2

-3 = -(10) + 7
-3 = -3

Since both coordinates work in C then C is the answer

Tess, who lives in the united states, is on a trip to europe. she is going first to germany, where the currency is the euro (€), and then to switzerland, where the currency is the swiss franc (chf). as she travels from germany to switzerland, she finds that she has the equivalent of $527 remaining in euros, which she wishes to convert to swiss francs. if, at the time of tess’s exchanges, the exchange rate of the us dollar to the euro is 1:0.6957 and the exchange rate of the euro to the swiss franc is 1:1.4755, how many swiss francs does she have? round all currencies to two decimal places. a. 366.63 francs b. 513.39 francs c. 540.96 francs d. 777.59 francs

Answers

answer:

c

explanation:

from dollars to euro

for every us dollar you have 0.6957 euros

so you time that (0.6957) by 527

which is

366.6339 euros

now we need to convert the euros to swiss franc

so we do 366.6339 euros times 1.4755

this will be 540.96831945 chf

rounding to 2 decimal places will be : 540.96

Maria bought 3 books for a total of $26. 25. How much did each book cost ?

Explanation -:

In this question it is given that Maria bought 3 books and the cost of 3 books is $26.25. We are asked to calculate the cost of 1 book.

We can find the cost of 1 book by dividing the total cost by number of books.

Cost of 1 book = $26.25 ÷ 3 = [tex]\dfrac{26.25}{3}[/tex] = 8.75

Verifying -:

Cost of 1 book = $8.75

Cost of 3 books = 8.75 × 3 = $26.25
