Answer:    y = 5x - 7

Step-by-step explanation:

y = mx + b, where m = slope

We plug in the point, where x = 2, and y = 3

y = 5x - b

3 = 5(2) - b

3 = 10 - b

b + 3 = 10

b = 7

y = 5x - 7

a < 5

step by step

4 - 4 = 0

9 - 4 = 5

Answer:

A. Homes using solar power always have lower utility bills than homes using only gas and electricity.

Step-by-step explanation:

Gas and Electricity

[tex]\bar x = 93[/tex]

[tex]\sigma = 11[/tex]

Solar

Bills: 56, 54 and 51

Required

Determine which of the statements is true

First, we calculate the mean of the given data

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\bar x = \frac{56 + 54 + 51}{3}[/tex]

[tex]\bar x = \frac{161}{3}[/tex]

[tex]\bar x = 53.67[/tex]

Then, the standard deviation

[tex]\sigma = \sqrt{\frac{\sum(x - x_i)^2}{n}}[/tex]

[tex]\sigma = \sqrt{\frac{(56 - 53.67)^2 + (54 - 53.67)^2 + (51 - 53.67)^2}{3}}[/tex]

[tex]\sigma = \sqrt{\frac{12.67}{3}}[/tex]

[tex]\sigma = \sqrt{4.223}[/tex]

[tex]\sigma = 2.05[/tex]

So, we have:

Gas or Electricity

[tex]\bar x = 93[/tex]

[tex]\sigma = 11[/tex]

Solar

[tex]\bar x = 53.67[/tex]

[tex]\sigma = 2.05[/tex]

By comparison.

The mean and standard deviation of homes using solar panel is less than home using gas and electricity.

This implies that: (a) is true.

Step-by-step explanation:

Answer:

A taco cost $1 while a burrito cost $1.79

Step-by-step explanation:

This may be computed as a set of simultaneous equations

Thelma ordered 2 tacos and 1 burrito and paid $ 3.79

let the cost of a taco be t and a burrito b then

2t + b = 3.79

Louise ordered 2 burritos and 1 taco and paid . \$4.58​

t + 2b = 4.58

solve both equations simultaneously

multiply the first by 2

4t + 2b = 7.58

t + 2b = 4.58

subtract 2 from 1

3t = 3

t = 1

t + 2b = 4.58

1 + 2b = 4.58

2b = 4.58 - 1

2b = 3.58

Divide both sides by 2

b = 1.79

A taco cost $1 while a burrito cost $1.79

Answer:

-9

Step-by-step explanation:

The city of Brussels will be the warmest. The difference in temperature between Oslo and London is -9°C and the temperature at 6:00 pm in Paris will be -2°C.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

(a)

A city which has the lowest temperature will be warmest since -1°C is the lowest so Brussels will have the warmest city.

(b)

The difference in temperature between Oslo and London will be as,

-12 °C - (-3 °C) = -9 °C.

(c)

At 6.:00 pm the temperature will be -5 °C + 3 °C = -2 °C.

Hence "The city of Brussels will be the warmest. The difference in temperature between Oslo and London is -9°C and the temperature at 6:00 pm in Paris will be -2°C".

Answer:

Step-by-step explanation:

13). [tex]-\frac{q}{7}\geq -1[/tex]

     [tex]\frac{q}{7}\leq 1[/tex]

    [tex](\frac{q}{7}\times 7)\leq (1\times 7)[/tex]

      q ≤ 7

14). -12x < 60

      12x > -60

      [tex]\frac{12x}{12}>\frac{-60}{12}[/tex]

      x > -5

15). 5 > z - 3

     5 + 3 > z - 3 + 3

     8 > z

16). 0.5 ≤ [tex]\frac{y}{8}[/tex]

     0.5 × 8 ≤ [tex]\frac{y}{8}\times 8[/tex]

     4 ≤ y

Now we can draw these inequalities on a number line.

Answer:

[tex]f^{-1}(x) = \sqrt[3]{\frac{x -4}{5}} +2[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 5(x - 2)^3 + 4[/tex]

Required

Determine the inverse

[tex]f(x) = 5(x - 2)^3 + 4[/tex]

Replace f(x) with y

[tex]y = 5(x - 2)^3 + 4[/tex]

Swap the positions of x and y

[tex]x = 5(y - 2)^3 + 4[/tex]

Make y the subject

[tex]x -4= 5(y - 2)^3[/tex]

Divide by 5

[tex]\frac{x -4}{5}= (y - 2)^3[/tex]

Take cube roots of both sides

[tex]\sqrt[3]{\frac{x -4}{5}}= y - 2[/tex]

Add 2 to both sides

[tex]\sqrt[3]{\frac{x -4}{5}} +2 = y[/tex]

[tex]y = \sqrt[3]{\frac{x -4}{5}} +2[/tex]

Replace y with [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(x) = \sqrt[3]{\frac{x -4}{5}} +2[/tex]

Answer:

54 cm

Step-by-step explanation:

Perimeter = TZ + TX + RX + RY + SY + SZ

TZ = 5 cm

TX = 13 cm

RY = 9 cm

RX = TX = 13 cm (tangents drawn from and external point)

SY = RY = 9 cm (tangents drawn from and external point)

SZ = TZ = 5 cm (tangents drawn from and external point)

Plug in the values:

Perimeter = 5 + 13 + 13 + 9 + 9 + 5 = 54 cm

Answer:

0.1348 = 13.48% probability that 3 of them entered a profession closely related to their college major.

Step-by-step explanation:

For each graduate, there are only two possible outcomes. Either they entered a profession closely related to their college major, or they did not. The probability of a graduate entering a profession closely related to their college major is independent of other graduates. This, coupled with the fact that they are chosen with replacement, 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.

53% reported that they entered a profession closely related to their college major.

This means that [tex]p = 0.53[/tex]

9 of those survey subjects are randomly selected

This means that [tex]n = 9[/tex]

What is the probability that 3 of them entered a profession closely related to their college major?

This is P(X = 3).

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

[tex]P(X = 9) = C_{9,3}.(0.53)^{3}.(0.47)^{6} = 0.1348[/tex]

0.1348 = 13.48% probability that 3 of them entered a profession closely related to their college major.
