Plsss fast

Answers

I believe the answer is: 490 students are most likely to ride the bus

We would expect about 490 students to ride the bus to school based on the sample

What is random sampling?

It is the way of choosing a number of required items from a population given.

Each item has an equal probability of being chosen.

We have,

If 7 out of every 12 students ride the bus to school, then the proportion of students who ride the bus is 7/12 or approximately 0.5833.

If we assume that this proportion holds true for the entire school, then we can estimate the number of students who ride the bus as follows:

Number of students who ride the bus = Proportion who ride the bus x Total number of students

Number of students who ride the bus = 0.5833 x 840

Number of students who ride the bus = 489.99

Since we cannot have a fractional number of students, we would round this estimate to the nearest whole number.

Thus,

We would expect about 490 students to ride the bus to school based on the sample

Owen is planning surgery to repair the torn ligament in his knee. The total cost of the surgery is expected to be about $7,000. Owen has a $1,000 deductible and then a 20 per- cent co-pay for this procedure. How much will Owen pay for his part of the surgery?

Answers

Answer:

$2200

Step-by-step explanation:

Given that Owen has $7000 to pay, with a $1000 deductible. This means that he has, left to pay, $6000.

Again, we're told that he has 20% Co pay for the procedure. Taking 20% of $6000, we have

20/100 * 6000 = $1200. This means be has $1200 to co pay for the procedure.

Adding this newly calculated $1200 with the previously set aside $1000, we have a total of $2200. This is the price Owen will pay from his part, as part of the surgery

what is the slope of the line that passes through the points (-1,-7) and (-2,-5)

Answers

Answer:

The equation of the straight line is

2 x + y +9=0

Step-by-step explanation:

Step(i):-

Given that the points are ( -1 , -7) and ( -2 , -5)

Slope of the line

[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-5-(-7)}{-2-(-1)} = \frac{-5+7}{-2+1} = -2[/tex]

Slope of the line  m = -2

Step(ii):-

The equation of the straight line passing through the point (-1,-7) and having slope m =-2

[tex]y - y_{1} = m( x- x_{1} )[/tex]

y - (-7) = - 2( x-(-1))

y +7 = -2 ( x +1)

y +7 = -2 x -2

2 x + y + 7 + 2 =0

2 x + y +9=0

Final answer:-

The equation of the straight line is

2 x + y +9=0

Kendra set a goal to walk 10 miles in one week. She walked 2 miles on Monday and 3 miles on Tuesday. Which equation represents the number of miles, w, Kendra still needs to walk?

Answers

Answer:

w + 5 = 1010 - 5 = w

Step-by-step explanation:

Kendra has a goal to walk 10 miles in one week.

She has already walked 2 miles on Monday and 3 miles on Tuesday. This means that she has already walked:

= 2 + 3

= 5 miles

If she wants to walk a total of 10 miles with w being the remaining miles, the expressions will therefore be:

w + 5 = 10

or;

10 - 5 = w

Libby bought 224 ounces of flour. If each bag contains 32 ounces of flour, how many bags of flour did Libby buy?

Answers

Answer:

answer is 7

Step-by-step explanation:

trust me :)

The number of bags of flour bought by Libby is given by A = 7 bags

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The total amount of flour bought by Libby = 224 ounces

The amount of flour in each bag = 32 ounces

Let the number of bags be A

So ,  amount of flour in each bag x number of bags = total amount of flour bought by Libby

On simplifying the equation , we get

32A = 224

Divide by 32 on both sides , we get

A = 224/32

A = 7 bags

Therefore , the value of A is 7 bags

Hence , the number of bags is 7 bags
