Answer:

how about question l 180_× + =

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

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

222

=

96

222

Then simplify

Answer:

Step-by-step explanation:

15(15b-7)=3b-9

225b-105=3b-9

        +105     +105

225b=3b+96

/3        /3

75b=b+96

/75      /75

b=b+1.28

Answer:

56.33

Step-by-step explanation:

because if 78+22=100 then you divide 78 by

21.67 which gets you the answer 56.33

Step-by-step explanation:

3x + 2y + z = 140

2x + 2y + 2z = 170

x + 3y + 2z = 180

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

Answer:

1100

Step-by-step explanation:

Number 1 in the decimal system

1012 = 510

Number 2 in the decimal system

1112 = 710

Their sum

5 + 7 = 12

Result in binary form

1210 = 11002

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.

Answer:

X=7

Step-by-step explanation:

5x - 15 =20

5x=15+30

5x=35

Divide by 5

X=7

Answer:

add 16 to both sides so it would 2x=-48 then you would divide 2 on both sides so it would be x=-24

Step-by-step explanation:

X=-24

Answer:

-16 + 2x = -64

+16 +16

2x = -48

-48÷2=-24

x = -24

Answer:

percent=25.56%

Step-by-step explanation:

Percentages

To know the percentage of having n elements out of a total of m elements, we calculate the ratio n/m and express the result as a percentage.

The shoe store has 23 pairs of white shoes out of 90 total pairs of shoes. The percent of white tennis shoes is calculated as follows:

[tex]\displaystyle percent= \frac{23}{90}*100\%[/tex]

Operating:

percent=25.56%

Answer:

1. 3.65%

2. 14,235

3. 49402.75

4. 185,795.04

5. 181,895.0375

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.]

Answer:
