Evaluate f(4)  for the function f(x)=3x-5
A.12
B.7
C.9
D.17​

Answers

Answer 1

the answer is b.7

Step-by-step explanation:

because you have to plug in the f(4) to the equation like this

f(4)=3(4)-5

and then multiple 3x4 which is 12 then subtract 12 and 5 and you get 7.

The figure shown has two parallel lines cut by a transversal: A pair of parallel lines is shown, crossed by a transversal. Angles are identified as 1, 2, 3, 4, 5, 6, 7, and 8. Angles 1-4 are on the top line clockwise from upper left. Angles 5-8 are on the lower line clockwise from upper left. Use the figure to complete the sentence. ∠7 and ____ are alternate exterior angles. ∠2 ∠1 ∠5 ∠8

Answers

*see attachement for the diagram of the figure being referred to

Answer:

<1

Step-by-step explanation:

Alternate exterior angles are a pair of angles which are located on the opposite side of the transversal, outside the two parallel lines.

From the figure given, you would see that <7 and <1 lie on opposite side of the transversal and they lie on the outside of the two parallel lines that are cut across by the transversal.

Therefore:

<7 and <1 are alternate exterior angles.

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 39 minutes ​? In 1 hour ​?

Answers

Answer: 45

Step-by-step explanation:  

1 and 3/4 miles               ???? miles

--------------------  = ---------------------

2 and 1/3 minutes         39 minutes

Cross multiplies:

(1 and 3/4) x 39 =   (2 and 1/3)  x    ?

7/4 x 39/1   = 7/3 x ?

273/4 = 7/3 x ?

? = 273/4 * 3/7 =  39*3/4   <---- 7 x 39 = 273

                        = 117/4

                         = 29 and 1/4

---------------------------------------------------------------

1 and 3/4 miles              ?

What is the solution to the system of equations graphed below?

y = 4x + 11

y = -2x - 1

Answers

Answer:

Step-by-step explanation:

y = 4x + 11, and y = -2x - 1, so

4x + 11 = -2x - 1

6x + 11  = -1

6x = -12

x = -2

y = 4x+11 = 3

y = 4x + 11

y = -2x - 1

4x + 11 = -2x - 1

4x + 2x = -1 - 11

6x = -12

x = -12/6

x = -2

y = 4x + 11

y = 4(-2) + 11

y = -8 + 11

y=3

Answer is (-2,3).

PLEASE HELP!!!!!! ILL GIVE BRAINLIEST *EXTRA 40 POINTS** !! DONT SKIP :((

Answers

Answer:

Yes

Step-by-step explanation:

So we substitute the point given x=-5 and y = -3 to see if this solves both equations at the same time so

3(-5) - 9(-3) = 12 ->  -15+27 = 12 -> 12 = 12 [this one works]

8(-5) - 14 (-3) = 2 -> -40 + 42 = 2 -> 2=2 [this one works also]

Since (-5,-3) is a solution to both equations, then this is a solution to this system

Answer: Yes

Step-by-step explanation:

Here

x = -5

y = -3

3x - 9y = 12

Here if you substitute x and y,

3 * (-5) - 9 * (-3)

(-15) - (-27)

=12

8x - 14y = 2

8 * (-5) - 14 * (-3)

(-40) - (-42)

= 2

The head-to-tail length of a species of fish is normally distributed, with a mean of 17.4 cm and a standard deviation of 3.2 cm. One fish is 15.3 cm long. What is the z-score of the length of this fish? Round your answer to two decimal places.
A. -0.86
B. -0.66
C. 0.86
D. 0.66

Answers

Answer:

B

Step-by-step explanation:

We have that for a normal distribution, the value of z can be calculated using the following formula:

z = (x - m) / sd

where x is the value to evaluate, m the mean and sd the standard deviation, we have those values x = 15.3, m = 17.4 and sd = 3.2

if we replace we have:

z = (15.3 - 17.4) /3.2

z = -0.65625

if we round to 2 decimal places, it would be -0.66, that is, the answer is B.

A Z-score helps us to understand how far the data is from the mean. The z-score of the given length of this fish is -0.66. The correct option is B.

What is Z-score?

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

z-score = (x-μ)/σ

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

Given that the length of a species of fish is normally distributed, with a mean(μ) and the standard deviation(σ) is 17.4 cm and 3.2 cm. Therefore, the z-score of the length of this fish is,

z-score = (x-μ)/σ

            = (15.3 - 17.4) / 3.2

            = -2.1/3.2

            = -0.65625

            = -0.66

Hence, the z-score of the given length of this fish is -0.66.

Answers

Given:

Total amount of bonus = $1,692

Bonus received by each employee = $53

To find:

The Number of people work for Hank’s Fried Chicken.

Solution:

We need to divide the total bonus by the bonus of each employee to get the number of people work for Hank’s Fried Chicken.

[tex]\text{Number of people}=\dfrac{\text{Total amount of bonus}}{\text{Bonus received by each employee}}[/tex]

[tex]\text{Number of people}=\dfrac{1692}{53}[/tex]

[tex]\text{Number of people}=31.92453[/tex]

Number of people must be whole number. So, approx the value to the preceding whole number.

[tex]\text{Number of people}\approx 31[/tex]

Therefore, 31 people work for Hank’s Fried Chicken.
