Josiah went to the local barber to get his hair cut. It cost $18 for a haircut. Josiah tipped the barber 15%. What was the total cost of the haircut including the tip?

Answer:

Step-by-step explanation:

add all internal angles

∠H + ∠I + ∠J = 180

where:

∠H = 3x - 2

∠I = 4x - 9

∠J = 3x - 9

plugin the values into the ∠H + ∠I + ∠J = 180 formula:

equation: 3x - 2 + 4x - 9 + 3x - 9 = 180

combine similar terms: 3x + 3x + 4x = 180 + 2 + 9 + 9

simplify: 10x = 200

divide 10 both sides: x = 20

Answer:

Step-by-step explanation:

You can break it down into steps if you'd like.

-5 ( 3h - 8) = -15h + 40

So,

7h - 5 ( 3h -8 ) = -72

7h - 15h + 40 = -72

Now you can combine the like terms

-8h + 40 = -72

Add 8h to both sides

40 = -72 + 8h

Add 72 to both sides

40 + 72 = 8h

112 = 8h

Divide both sides by 8 to find h.

h = 112/8 = 14

Answer:

the answer should be 414

Answer:

414

or

103.5

Step-by-step explanation:

If these are singular values and for example 2 x 105 does not mean two datasets of 105 and 6 x 103 doesnt mean six datasets of 103, then your average would be as follows

((2 x 105) + (6*103)) ÷ 2

The two being how many sets of values you have

This would be solved as follows

((210) + (618)) ÷ 2 =

            (828) ÷ 2 = 414

So in this case it would be 414

However, if the two in 2 x 105 means two data sets of 105;

it would be the same steps of solving but with the ÷ 2 being replaced with ÷ 8 (2 + 6)

((2 x 105) + (6*103)) ÷ 8 =

        ((210) + (618)) ÷ 8 =

                    (828) ÷ 8 = 103.5

The value of measure ∠RQS would be,

⇒ ∠RQS = 48°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

A ray QT bisects ∠PQR.

Now, We get;

⇒ ∠PQR + ∠RQS = 180°

⇒ (3x - 6) + (x + 2) = 180

⇒ 4x - 4 = 180

⇒ 4x = 184

⇒ x = 46

Thus, The value of measure ∠RQS would be,

⇒ ∠RQS = x + 2 = 46 + 2 = 48°

Answer:

  216.66 yd²

Step-by-step explanation:

One way to find the area of a ring like this is to multiply its centerline length by the width of the ring.

Here, the diameter of the circle that is the centerline of the ring is 23 yd. The circumference of that circle is ...

  C = πd = 3.14(23 yd) = 72.22 yd

Then the ring area is ...

  (72.22 yd)(3 yd) = 216.66 yd² . . . area of shaded region

Step-by-step explanation:

The sample mean is both values added together then divided by 2.

$46.63

The margin of error is the low value divided by the high value * 100% =76.8% (then you have to minus this from 100% so the margin of error is 23.2%)

Complete Question

The chance of an IRS audit for a tax return with over $25,000 in income is about 2% per year. We are interested in the expected number of audits a person with that income has in a 9-year period. Assume each year is independent.

Find the probability that a person is audited more than twice. (Round your answer to four decimal places.)

Answer:

The probability is  [tex]P(X > 2) = 0.0007 [/tex]

Step-by-step explanation:

From the question we are told that

The  probability of an IRS audit for a tax return with over $25,000 in income is p= 0.02

The sample size  n  =  9

Generally the distribution of IRS audit for a tax return follows a binomial distribution  

i.e  

         [tex]X  \~ \ \ \  B(n , p)[/tex]

and the probability distribution function for binomial  distribution is  

      [tex]P(X = x) =  ^{n}C_x *  p^x *  (1- p)^{n-x}[/tex]

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

Generally the probability that a person is not audited at all is mathematically

     [tex]P(X = 0) =  ^{9}C_0 *  (0.02)^0 *  (1- 0.02 )^{9-0}[/tex]

      [tex]P(X = 0) =  ^{9}C_0 *  (0.02)^0 *  (0.98 )^{9-0}[/tex]

       [tex]P(X = 0) =  0.8337[/tex]

Generally the probability that a person is  audited once  is mathematically

           [tex]P(X = 1) =  ^{9}C_1 *  (0.02)^1 *  (1- 0.02 )^{9-1}[/tex]

           [tex]P(X = 1) =  9*  (0.02)^1 *  (0.98 )^{8}[/tex]

            [tex]P(X = 1) =  0.1531[/tex]

Generally the probability that a person is  audited twice is mathematically represented

           [tex]P(X = 2) =  ^{9}C_2 *  (0.02)^2 *  (1- 0.02 )^{9-2}[/tex]

           [tex]P(X = 2) =  36 *  (0.02)^2 *  (0.98 )^{7}[/tex]

            [tex]P(X = 2) =  0.0125 [/tex]

Generally the probability that a person is audited more than twice is mathematically represented

     [tex]P(X > 2) =  1 - [P(X = 0 ) + P(X = 1 )+ P(X =2)] [/tex]

=>    [tex]P(X > 2) =  1 - [0.8337 + 0.1531+0.0125 ] [/tex]

=>    [tex]P(X > 2) = 0.0007 [/tex]
