Someone please help me asap. I’m confused and need help. Complete the table using the function n = 9b + 19

Answers

answer: you would just substitute all of the values you see for b into the equation where there's a b

Answer:

55; 64; 73

Step-by-step explanation:

In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19

if b = 4:

n = 9(4) + 19

n = 36 + 19

n = 55

if b = 5:

n = 9(5) + 19

n = 45 + 19

n = 64

if b = 6:

n = 9(6) + 19

n = 54 + 19

n = 73

Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it

if b = 7:

n = 9(7) + 19

n = 63 + 19

n = 82

Work is correct

Try not to overthink it ^-^

Inspectors for a hospital chain with multiple locations randomly select some of their locations for a cleanliness check of their operating rooms. The inspectors check every operating room in the hospitals that were chosen. What sampling method was used?

Answers

Answer:

Cluster Random Sample

Step-by-step explanation:

The operating rooms were divided into (hospital locations) and inspectors sampled every operating room from some of the groups.

Sampling method is the method where the subset of an overall population is selected.

The sampling method used was cluster sampling

From the question, we understand that:

The inspectors select some locationsThen all selected locations was checked

The above illustrates cluster sampling.

This is so because, cluster sampling involves breaking down a population into smaller size.

In this case, the smaller size are the locations that were selected.

The sum of five consecutive even integers is 220. Find the middle value of the five consecutive integers.

Answers

Answer:

             44

Step-by-step explanation:

If we have odd number of consecutive numbers increasing by the same value (2) then the middle value of them is their mean:

220:5 = 44

Of course you can find them to be sure:

Consecutive even integers increase by 2.

So if 2x is the smallest of them (x is an integer), then the numbers are:

2x,  2x+2,  2x+4,  2x+6,  2x+8

So their sum:   10x+20

10x + 20 = 220  ⇒  10x = 200  ⇒  2x = 40

So the numbers are: 40, 42, 44, 46, 48

What is Inequality?

Inequalities are mathematical formulas in which neither side is equal.

As per the given data:

We are given two inequalities, and we have to find out whether the points that are given in the options are satisfying the solution set of the given inequalities or not.

The inequalities are as follows:

x + y > 2

4x + y ≥ -1

For option (A). (2, 0)

Substituting the points in the given inequalities.

2 > 2 and 8 ≥ -1

Hence, this is incorrect.

For option (B). (0, 2)

Substituting the points in the given inequalities.

2 > 2 and 2 ≥ -1

Hence, this is incorrect.

For option (C). (0, 3)

Substituting the points in the given inequalities.

3 > 2 and 3 ≥ -1

Hence, this is correct.

For option (D). (0, -1)

Substituting the points in the given inequalities.

-1 > 2 and -1 ≥ -1

Hence, this is incorrect.

What is m∠PQR?

The PS is line segment. Q is the point between segments PS. QR is another line segment passes through segment PS. The angle PQR is (3x + 5) degree and angle SQR is (x + 3) degree.

Answers

Answer: m∠PQR = 134°

Step-by-step explanation:

Given:  PS is line segment. Q is the point between segment PS. QR is another line segment passes through segment PS.

That means ∠PQR and ∠SQR are linear pair  [Linear pair is a pair of two angles made on one line and their sum is 180°]

⇒  ∠PQR +  ∠SQR  = 180°  (i)

Since, ∠PQR is (3x + 5)° and ∠ SQR is (x + 3)°   [given]

Put this in (i), we get

(3x + 5)° + (x + 3)° = 180°

⇒ 3x + 5 + x + 3 = 180

⇒ 4 x + 8 = 180

⇒ 4 x = 180-8

⇒ 4 x = 172

Divide both sides by 4

⇒  x= 43

So,  ∠PQR=  (3(43) + 5)° = 134°

Hence, m∠PQR = 134°

The measure of m ∠PQR is 134 degrees.

Given

PS is a line segment.

Q is the point between segment PS.

QR is another line segment that passes through segment PS.

Which property of the triangle is used to solve the value of x?

The sum of two angles made on one line is equal to 180 degrees.

[tex]\angle \rm PQR + \angle SQR = 180[/tex]

Where the angle QPR is (3x + 5) degree and angle SQR is (x + 3) degree.

Substitute all the values in the equation

[tex]\angle \rm PQR + \angle SQR = 180\\\\(3x+5) + (x+3) =180\\\\3x+5+x+3=180\\\\4x+8=180\\\\4x=180-8\\\\4x=172\\\\x = \dfrac{172}{4}\\\\x =43[/tex]

The value of x is 43 degrees.

Therefore,

The measure of m ∠PQR is;

[tex]\rm m \angle PQR = 3x+5 = 3(43) + 5= 129+5=134[/tex]

Hence, the measure of m ∠PQR is 134 degrees.

Solve for x in the following equation:
kx = m + nx

Answers

Answer:

x = [tex]\frac{m}{k-n}[/tex]

Step-by-step explanation:

Given

kx = m + nx ( subtract nx from both sides )

kx - nx = m ← factor out x from each term on the left side

x(k - n) = m ← divide both sides by (k - n)

x = [tex]\frac{m}{k-n}[/tex]

Solving for x in the equation, kx = m + nx, we would make x the subject of the formula to solve for x as: [tex]\mathbf{x = \frac{m}{k - n}}[/tex]

Given:

kx = m + nx

We are require to make x the subject of the formula.

Thus:

[tex]kx = m + nx[/tex]

Subtract nx to both sides of the equation

[tex]kx - nx = m + nx - nx\\\\kx - nx = m[/tex]

Factor out x on the left side

[tex]x(k - n) = m[/tex]

Divide both sides by (k - n)

[tex]\frac{x(k - n)}{k - n} = \frac{m}{k - n} \\\\x = \frac{m}{k - n}[/tex]

Therefore, solving for x in the equation, kx = m + nx, we would make x the subject of the formula to solve for x as: [tex]\mathbf{x = \frac{m}{k - n}}[/tex]

$21.00 / $1.50 = 14

Answer:

He has $25, and spends $4. So 25 - 4 = 21. Each ride ticket is $1.50. So 21 ÷ 1.50 = 14

You decide to go to the candy store in the mall. You arrive at the store with $25 and then purchase 3 candy bars. You then buy a giant candy snake for $12.50. When you leave, you have $8.75 left in your wallet. How much did each candy bar cost? Write the equation to represent the scenario. 8.75 - x - 12.50 = 25.00 25.00 - 3x - 12.50 = 8.75 25.00 - 3x - 8.75 = 12.50 25.00x - 12.50 = 8.75

Answers

Answer:

The cost of a candy is $1.25

Step-by-step explanation:

given the total amount at hand is $25

let the price of  candy be x

then the cost of 3 candy will  be 3x

the cost of a candy snake is $12.50.

balance at hand after the end of buying $8.75

the total expenses summed up must equal the initial amount at hand which is $25

the expression for the scenario is 3x+12.5+8.75=25

3x+21.25=25

3x=25-21.25

3x=3.75

x=3.75/3

x=$1.25

The cost of a candy is $1.25

How many years will it takes an investment of 3000$ to amount to 5,000 if money is invested at 4.1% compounded monthly

Answers

Answer:

1.66

Step-by-step explanation:

The years needed to make $3000 to $5000 is 12.5.

What is compound interest?

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, an investment of $3000 to amount to 5,000 if money is invested at 4.1% compounded monthly

A = P(1+r/12)^12t

5000 = 3000(1+0.041/12)^12t

5/3 = (1.0034)^12t

Taking log both sides,

log5/3 = 12tlog(1.0034)

0.221 = 12t0.00147

12t = 150.34

t = 12.5

Hence, required years are 12.5.
