Answer:

Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

Step-by-step explanation:

Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].

It's always a good idea to put these equations under each other:

[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]

We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]

Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

A consumer organization inspecting new cars found that many had appearance defects (dents, scratches, paint chips etc.). No car had more than three defects. Here is the probability distribution for the number of appearance defects in a new car. X: number of defects 0 1 2 3 P(x) 0.61 0.21 0.11 0.07 Find the expected number of appearance defects in a new car. Do not round.

Answers

Answer:

The expected number of appearance defects in a new car is 0.64.

Step-by-step explanation:

To find the expected number of appearance defects in a new car, we multiply each outcome by its probability.

We have that:

0.61 probability of 0 defects

0.21 probability of 1 defect

0.11 probability of 2 defects

0.07 probability of 3 defects

0.61*0 + 0.21*1 + 0.11*2 + 0.07*3 = 0.64

The expected number of appearance defects in a new car is 0.64.

Write the equation in Point-Slope Form of a line that has a slope of 3/4 and passes through point (-4, -12).

Answers

Answer:

The equation in Point-slope form of a line that has a slope of 3/4 and passes through the point (-4, -12) is:

[tex]y+12=\frac{3}{4}\left(x+4\right)[/tex]

The graph of the equation line is also attached below.

Step-by-step explanation:

Given

Slope m = 3/4Point (-4, -12)

To determine

We have to determine the equation in Point-Slope Form.

We know that the Point-slope form of a line equation is defined as

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

[tex]m[/tex] is the slope of the line[tex]\left(x_1,\:\:y_1\right)[/tex] is the point

In our case:

Slope m = 3/4(x₁, y₁) = (-4, -12)

substituting the values m = 3/4 and the point (x₁, y₁) = (-4, -12) in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-12\right)=\frac{3}{4}\left(x-\left(-4\right)\right)[/tex]

Apply rule: [tex]-\left(-a\right)=a[/tex]

[tex]y+12=\frac{3}{4}\left(x+4\right)[/tex]

Therefore, the equation in Point-slope form of a line that has a slope of 3/4 and passes through the point (-4, -12) is:

[tex]y+12=\frac{3}{4}\left(x+4\right)[/tex]

The graph of the equation line is also attached below.

Find the Area Of This Figure.

Answers

24 in
to find area of rectangle L x W
it comes out to be 18
to find area of trapezoid 1/2 BxH
so it comeS out to be 6
add them together and get 24

Answer:

42in

Step-by-step explanation:

First divide up the shape.

The bottom will cut off to form a 6x3 rectangle which will have an area of 18in. Next is the top portion which is a trapezoid. You can figure out the area two ways. You can divide it further into two triangles and a rectangle. Or you can use the trapezoid formula. In this case I feel like dividing it. So since the top is 2 inches the bases of the two side triangles must be 2 due to the bottom base of the whole shape being 6. (1/2*2*6)*2 = 12in. Lastly the center rectangle is 2*6 (got 6 from 9-3) which is also 12. So the top half added together 12+12 equals 24in. When adding both top and bottom portions (18+24) you get 42in.

E. 1
O F. 4

Answers

Answer:

D. √2

Step-by-step explanation:

Solve for x by applying trigonometric ratio.

Reference angle = 45°

Hypotenuse = 2

Adjacent side = s

Thus:

Cos (45) = adj/hyp

Cos (45) = s/2

2×Cos(45) = s

2 × √2/2 = s (cos (45) = √2/2)

√2 = s

s = √2

The net for a triangular prism is shown below. What is the total surface area of the prism? 6.9 cm 8 cm 10 cm 8 cm 0 55.2 square centimeters 0 295.2 square centimeters 0 240 square centimeters 0 552 square centimeters

Answers

Answer:

Step-by-step explanation:

The area of each rectangle is Length x width

Therefore Area of rectagle is 8cm x 10 cm=

A= 80 cm 2

There are three rectangles with the same measure so multiply the area by 3

80cm squared x 3= 240 cm 2

Now find the are of the triangle:

A- 1/2 x base x height

Base = 8cm

Height = 6.9 cm

A= (1/2) (8cm) (6.9cm)

A= (1/2) (55.2 cm squared)

A= 27.6 cm squared

Since there are two triangle faces with the same dimensions take the area and multiply it by 2

27.6 cm squared times 2 = 55/2 cm squared

Now add up the area of the rectangles and the area of the triangles.

Rectangles= 240 cm squared

Triangles 55.2 cm squared

240cm sq + 55.2 cm sq.= 295.2 cm squared

29 days to lay all the track

b)
5*19 = 95

145-95 = 50

After 19 days, they have 50 miles to go.

Answer:

Step-by-step explanation:

(a)

well since they can lay 7 miles of track every day, the formula i make for the amount of track there is left to lay is:

L=196-Ld

where l is the length of track remaining, L is the length of track they can lay in one day and d is the number of days.

so we replace L for 7 and d for 17 and we get:

L=196-7x17

which works out to be 77 miles of track remaining to lay.

(b)

well since we want them to have 0 length of track remaining, and they can lay 7 miles of track a day, we can work out d. let's give the formula a bash to get:

d=196-l/L

we then replace l with 0 and L with 7 and get:

d=196/7

which works out to be 28. so it will take 28 days or 4 weeks for the railroad crew to lay 196 miles of track.
