PLS HELP ME! Write A Rule (function) For The Data In This Table.

Answers

Answer 1

Answer:

y = x - 3

How I know I'm correct:

if you plug in the numbers from the table, it checks out.

y = x - 3

0 = 3 - 3

0 = 0

y = x - 3

1 = 4 - 3

1 = 1

y = x - 3

2 = 5 - 3

2 = 2

and so on

Answers

Answer:

x/2 + 3

Step-by-step explanation:

Shaun sold x tickets.

Trudy has sold 3 more tickets than half the number of tickets that Shaun sold.

Half the number Shaun sold is x/2.

3 more than that is x/2 + 3

Answer: x/2 + 3

Answer:

x/2 +3 + x

Step-by-step explanation:

Trudy sold x/2 + 3 tickets compared to shaun. So the total number of tickets they sold overall is x/2 +3 + x.

A purple hot-air balloon is 90 feet off the ground and rising at a rate of 7 feet per second. A yellow hot-air balloon is 120 feet off the ground and rising at a rate of 4 feet per second. Which equation could represent this situation and determine after how many seconds, s, the purple hot-air balloon will be the same height as the yellow hot-air balloon?
1 point
90 + 7s = 120 + 4s
7s + 120 = 4s + 90
90s + 7 = 120s + 4
11s = 210

Answers

90+7s = 120 + 4s

11s = 210

15(15b−7)=3b−9 plz help meee

Answers

Answer:

B=16over37

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15(15b−7)=3b−9

(15)(15b)+(15)(−7)=3b+−9(Distribute)

225b+−105=3b+−9

225b−105=3b−9

Step 2: Subtract 3b from both sides.

225b−105−3b=3b−9−3b

222b−105=−9

Step 3: Add 105 to both sides.

222b−105+105=−9+105

222b=96

Step 4: Divide both sides by 222.

222b

find the standard deviation

Answers

Answer:

d. 7.3

Step-by-step explanation:

To get the standard deviation of a population of data, first take the sum of all the values, and divide it by the count to get the mean (average).

75 [1] + 90 [2] + 75 [3] + 80 [4] + 90 [5] + 80 [6] + 100 [7] + 85 [8] + 80 [9] + 85 [10] = 840.

Then divide by the count which is 10.

840/10 = 84 [This is the mean of the data.]

Then subtract every point of data from the mean and square it:

(75-84)^2 + (90-84)^2 + (75-84)^2 + (80-84)^2 + (90-84)^2 + (80-84)^2 + (100-84)^2 + (85-84)^2 + (80-84)^2 + (85-84)^2 = 81 + 36 + 81 + 16 + 36 + 16 + 256 + 1 + 16 + 1 = 540.

Then to get the variance, divide this all by the count.

540/10 = 54 [This is the variance of the data.]

Then all you have to do to get the standard deviation is take the square root of the variance.

√54 = 3√6 ≈ 7.3 [This is the standard deviation of the data.]

Elijah is trying to make extra money on his summer vacation from school. He works two different jobs, earning $8 per hour babysitting and $10 per hour lifeguarding. How much money would Elijah earn in a week in which he worked 3 hours babysitting and 7 hours lifeguarding?

Answers

Answer:

$94

Step-by-step explanation:

8x + 10x =  y

8 (3) + 10 (7) = y

24 + 70 = y

94 = y

Answer with step-by-step explanation:

If he were to work a full week, then 3 hours babysitting × 7 days a week × $8 for work = $168 for babysitting. 7 hours lifeguarding × 7 days a week × $10 for work = $490 for lifeguarding.

The total amount of money that Elijah would earn is $168 + $490 = $658

Suppose you have a total of $2.25 in dimes and
nickels. You have twice as many dimes, as nickels.
Which system of equations could be used to
determine how many of each coin you have?

Answers

Answer:

n = number of nickels

2n = number of dimes

n($0.05) + 2n($0.10) = $2.25

0.05n + 0.2n = 2.25

0.25n = 2.25

n = 2.25/0.25 = 9

2n = 2(9) = 18

You has 9 nickels and 18 dimes

Determine the area under the standard normal curve that lies to the right of the z-score of 1.44. (Use a four-digit decimal. No rounding necessary.)

Answers

Answer:

The area is 0.0749

Step-by-step explanation:

The area under the standard normal curve represents probability and has a total value of 1

Now, to the right of the z-score 1.44, the area we are considering is the probability below;

P( z > 1.44)

To get this value, we need to use the standard normal distribution table

Checking this, the probability is

P( z > 1.44) = ) = 0.074934 which is 0.0749 for a four decimal digit

Evaluate f(x) = -2x - 5 for x = 3.
A. 11
B. -6
C. -11
D. 1

Answers

Answer:

C. -11

Step-by-step explanation:

f(x) = -2x - 5

Plug the 3 in for x

f(3) = -2(3) - 5

Multiply the -2 and 3

f(3) = -6 - 5

Subtract 5 from -6

f(3) = -11

Answer: C -11

Step-by-step explanation:

Its asking you to solve for f(x) which is Y

Y=-2x-5

X is 3

so replace -2x with 3 but only the x

you should get -23 not negative 23 its more of 2 times 3

then multiply -2 by 3 and get -6

add -6 and -5 to get -11
