Answer:

  y = -3x +4

Step-by-step explanation:

The hint tells you the slope stays the same. Every point moves to 2 times its original distance from the origin. So, the new y-intercept will be (+2)(2) = +4. The dilated line is ...

  y = -3x +4

Answer: 9.6

Step-by-step explanation:

You need to isolate the m and in order to do that then you have to multiply both sides by 2

So m/2 x 2 = m

4.8 x 2 = 9.6 which is the answer

Answer:

Step-by-step explanation:

m/2 = 4.8

m = 4.8×2

m = 9.6

Answer:

28.3

Step-by-step explanation:

Given,

Radius of the circle = 4.5 m

Therefore,

Circumference of the circle

[tex] = 2\pi r[/tex]

[tex] = 2 \times 3.14 \times 4.5[/tex]

= 28.26

Rounded to nearest tenth,

= 28.3 (Ans)

Answer:

6.5 boxes

Step-by-step explanation:

Given

See attachment for closet

Required

Determine the number of boxes needed to fill the closet

First, we calculate the volume of the two section.

According to the attachment

The first section has the following dimension:

[tex]Width = 5ft[/tex]

[tex]Length = 4ft[/tex]

[tex]Height = 8ft[/tex]

The second has the following dimension:

[tex]Width = 3ft[/tex] ---- see the last label at the top

[tex]Length = 2ft[/tex] --- This is calculated by subtracting the length of the first section (4ft) from the total length of the closet (6ft) i.e. 6ft - 4ft

[tex]Height = 8ft[/tex]

So: The volume of the closet is:

[tex]Volume = W_1 * L_1 * H_1 + W_2 * L_2 * H_2[/tex]

[tex]Volume = 5ft * 4ft * 8ft + 3ft * 2ft * 8ft[/tex]

[tex]Volume = 160ft^3 + 48ft^3[/tex]

[tex]Volume = 208ft^3[/tex]

The number of box needed is then calculated by dividing the volume of the closet (208ft^3) by the volume of each box (32ft^3)

[tex]Boxes = \frac{208ft^3}{32ft^3}[/tex]

[tex]Boxes= \frac{208}{32}[/tex]

[tex]Boxes = 6.5[/tex]

Answer:

[tex]\Large \boxed{\sf a)\ 128 \ liters \ \ \ b)\ \$ \ 115.20}[/tex]

Step-by-step explanation:

a) distance/unit rate = 1600/12.5 = 128

b) liters of gas × unit price = 128 × 0.90 = 115.2

Answer:

a) 128 liters

b) $ 115.2

Step-by-step explanation:

Part a)

12.5 km = 1 liter

1 km = 1/12.5 liters

Multiplying both sides by 1,600

1600 km = 1600 / 12.5 liters

1600 km = 128 liters

Part b)

1 liter = $ 0.90

128 liters = 128 * 0.90

128 liters = $ 115.2

Answer:

x = 29

Step-by-step explanation:

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c^{2} = 20^{2} + 21^{2}[/tex]

[tex]c^{2} = 400 + 441[/tex]

[tex]c^{2} = 841[/tex]

[tex]\sqrt{c^2} = \sqrt{841}[/tex]

[tex]c = 29[/tex]

As per the Pythagorean theorem, the value of 'x' for the given right angle triangle is 29.

"The Pythagorean theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides. Observe the following triangle ABC, in which we have BC² = AB² + AC²​​. Here, ​​​​AB is the base, AC is the altitude (height), and BC is the hypotenuse."

Given, the value of the three sides of the right angle triangle are 20, 21, and 'x'.

Here, x = the hypotenuse of the right angle triangle.

Therefore, using the Pythagorean theorem, we get:

x² = 20² + 21²

⇒ x² = 400 + 441

⇒ x² = 841

⇒ x = √(841)

⇒ x = 29 (ignoring the negative value of the square root)

Therefore, the value of 'x' is 29.

Answer:

a) 0.0000001024 probability that he will answer all questions correctly.

b) 0.1074 = 10.74% probability that he will answer all questions incorrectly

c) 0.8926 = 89.26% probability that he will answer at least one of the questions correctly.

d) 0.0328 = 3.28% probability that Richard will answer at least half the questions correctly

Step-by-step explanation:

For each question, there are only two possible outcomes. Either he answers it correctly, or he does not. The probability of answering a question correctly is independent of any other question. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Each question has five answers, of which only one is correct

This means that the probability of correctly answering a question guessing is [tex]p = \frac{1}{5} = 0.2[/tex]

10 questions.

This means that [tex]n = 10[/tex]

A) What is the probability that he will answer all questions correctly?

This is [tex]P(X = 10)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 10) = C_{10,10}.(0.2)^{10}.(0.8)^{0} = 0.0000001024[/tex]

0.0000001024 probability that he will answer all questions correctly.

B) What is the probability that he will answer all questions incorrectly?

None correctly, so [tex]P(X = 0)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{10,0}.(0.2)^{0}.(0.8)^{10} = 0.1074[/tex]

0.1074 = 10.74% probability that he will answer all questions incorrectly

C) What is the probability that he will answer at least one of the questions correctly?

This is

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

Since [tex]P(X = 0) = 0.1074[/tex], from item b.

[tex]P(X \geq 1) = 1 - 0.1074 = 0.8926[/tex]

0.8926 = 89.26% probability that he will answer at least one of the questions correctly.

D) What is the probability that Richard will answer at least half the questions correctly?

This is

[tex]P(X \geq 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{10,5}.(0.2)^{5}.(0.8)^{5} = 0.0264[/tex]

[tex]P(X = 6) = C_{10,6}.(0.2)^{6}.(0.8)^{4} = 0.0055[/tex]

[tex]P(X = 7) = C_{10,7}.(0.2)^{7}.(0.8)^{3} = 0.0008[/tex]

[tex]P(X = 8) = C_{10,8}.(0.2)^{8}.(0.8)^{2} = 0.0001[/tex]

[tex]P(X = 9) = C_{10,9}.(0.2)^{9}.(0.8)^{1} \approx 0[/tex]

[tex]P(X = 10) = C_{10,10}.(0.2)^{10}.(0.8)^{0} \approx 0[/tex]

So

[tex]P(X \geq 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) = 0.0264 + 0.0055 + 0.0008 + 0.0001 + 0 + 0 = 0.0328[/tex]

0.0328 = 3.28% probability that Richard will answer at least half the questions correctly

I think it could be $200 because if they're selling 6 pounds for 48 then each pound must be 8 so 25*8

Let y = f(x)

Let cr = cube root for short

y = cr{3x} + 2

Switch x and y.

x = cr{3y} + 2

Solve for y.

x - 2 = cr{3y}

Raise both sides to the 3rd power.

(x - 2)^3 = [cr{3y}]^3

(x - 2)^3 = 3y

[(x - 2)^3]/3 = y

Replace y with the inverse function notation

f^(-1) x.

f^(-1) x = [(x - 2)^3]/3

Choice b is the answer.

Answer:

12.8 IN.

Step-by-step explanation:

So, what exactly is perimeter?

Perimeter= 2L+ 2W

In this question we were given the length.ie.Base and the perimeter itself.

●Length is 39 In.

●Perimeter is 103.6 In.

●We don't know the width.

But, as per given the question, we know that;

1 length = 39 In.

2 lengths= 78 In.

Now that we know the total length we can find the total width.

See as follows,

103.6 - 78= 25.6

2 widths= 25.6

1 width= 25.6÷2

=12.8 In

Answer:

90 cubes.

Step-by-step explanation:

First we find volume of the cuboid.

Volume = l x b x h = 20 x 18 x 16 = 5760 cm³

Now,

Volume of a single cube = l³ = 4³ = 64

No of cubes that can be cut out from the cuboid is

= Volume of cuboid/ volume of cube

= 5760/ 64

= 90 cubes

Answer:

a)

the probability that Fischer wins the match is 0.5714

b)

p( D = d ) = { [tex]( 0.3 )^{d-1[/tex] [tex](0.7)[/tex],  d = 1, 2, 3, ........

                                 [tex]0[/tex]                     otherwise

Step-by-step explanation:

Given that;

probability that Fischer wins the match, p = 4

probability that Spassky wins the match, q = 0.3

Match drawn, 1 - p - q = 1 - 0.4 - 0.3 = 0.7

(a) What is the probability that Fischer wins the match?

P( Fischer wins) = p/( p+q)

we substitute

P( Fischer wins) = 0.4 / ( 0.4 + 0.3)

P( Fischer wins) = 0.4 / 0.7

P( Fischer wins) = 0.5714

Therefore, the probability that Fischer wins the match is 0.5714

b) What is the PMF of the duration of the match?

let D represent the duration of the match

since the duration D of the match is a geometric random variable with parameter p + q,

the PMF will be;

p( D = d ) = [tex]( 1 - p - q )^{d-1[/tex] ( p + q )

= [tex]( 1 - 0.4 - 0.3 )^{d-1[/tex] ( 0.4 + 0.3 )

p( D = d ) = [tex]( 0.3 )^{d-1[/tex] ( 0.7)

that is, p( D = d ) = { [tex]( 0.3 )^{d-1[/tex] [tex](0.7)[/tex],  d = 1, 2, 3, ........

                                 [tex]0[/tex]                     otherwise
