Answer:

$9.68

Step-by-step explanation:

The total cost before tax is $75.50 + $12.50 = $88

11% of $88 = 0.11 * $88 = $9.68

Answer: $9.68

Answer:

Step-by-step explanation:

$75.50 (bike) + $12.50 (helmet) = $88 (this is the amount shawn will pay before tax

next $88 (total before tax) multiplied by 0.11 (11% tax) to get $9.68 tax. that should be the answer

Complete Question

Answer:

a

The  97% confidence interval is  [tex]1528  <  \mu <  1612 [/tex]

b

Option A and  Option D  are correct

Step-by-step explanation:

From the question we are told that

     The sample size is n =  119

     The  sample  mean is [tex]\$ 1570[/tex]

    The  population standard deviation is  [tex]\sigma  =  \$ 211[/tex]

    Generally given that the confidence level is  97% then the level of significance is mathematically represented as

      [tex]\alpha = (100 - 97 )\%[/tex]

=>    [tex]\alpha = 0.03[/tex]

From the normal  distribution table  the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

     [tex]Z_{\frac{\alpha }{2} } =  2.17[/tex]

Generally the margin of error is mathematically represented as

     [tex]E =  Z_{\frac{\alpha }{2} } *  \frac{\sigma}{\sqrt{n} }[/tex]

    [tex]E =  2.17*  \frac{211}{\sqrt{ 119 } }[/tex]

=>   [tex]E =   41.98 [/tex]

Generally the 97% confidence interval is mathematically represented as

     [tex]\= x  - E  <  \mu <  \= x  + E[/tex]

=>    [tex]1570  - 41.98  <  \mu <  1570  + 41.98 [/tex]

=>    [tex]1528  <  \mu <  1612 [/tex]

Generally looking at confidence interval we see that the width is dependent on the size of the margin of error.

Generally the margin error is directly proportional to the  critical value of  [tex]\frac{\alpha }{2}[/tex] which increases when the confidence level increases and vise versa

Also the margin error is inversely proportional to the square root of  sample size

Hence to reduce the width of the confidence interval we need to lower the confidence level  and increase the sample size

Answer:

Step-by-step explanation:

1) Upon studying the grid, we see that A is at the intersection of the x- and y-axes, and that all of the other points are in the first quadrant. The distance between minor grid lines in either direction is taken to be 1 unit. That is, B is 1 unit right and 1 unit up from A(0, 0), so has coordinates B(1, 1).

The coordinates of C and D can be found by counting grid lines. We find them to be C(5, 1) and D(8, 7).

__

2) The line joining A and B is a line whose points have their x-coordinate equal to their y-coordinate. The coordinates of D are not equal, so will not be on that line.

Answer:

  A, B, C

Step-by-step explanation:

The variables in a polynomial term are non-negative integers.

  A: x is to 1/2 power (square root) . . . not a polynomial

  B: x is to -2 power . . . not a polynomial

  C: x is to -2 power . . . not a polynomial

  D: x is to powers of 2 and 1 . . . is a polynomial

The choices A, B, and C are not polynomials

Answer:

The complete question seems to be:

A doctor sees between 7 and 12 patients each day.

On Mondays and Tuesdays, the appointment times are 15 minutes.

On Wednesdays and Thursdays, they are 30 minutes.

On Fridays, they are one hour long.

The doctor works for no more than 8 hours a day.

Here are some inequalities that represent this situation.

0.25 ≤ y ≤ 1

7 ≤ x ≤ 12

xy ≤ 8

What represents each variable?

7 ≤ x ≤ 12

We know that the doctor sees between 7 and 12 patients each day, and the smallest value of x is 7, and the largest is 12, then x must represent the number of patients that the doctors see in a given day.

0.25 ≤ y ≤ 1

now,

On Mondays and Tuesdays, each appointment is 15 minutes long.

An hour has 60 minutes.

Then 15 minutes = 15/60 hours = 0.25 hours.

On Wednesdays and Thursdays, they are 30 minutes.

30 minutes = 30/60 hours = 0.5 hours.

Then the possible value of the time for each appointment are {0.25, 0.5, 1}

Then the variable y must represent the time that each appointment takes.

xy ≤ 8

We know that:

x =  number of patients in a given day.

y = time that the appointment takes in a given day.

x*y = total number of hours that he works in that given day.

and we know that he works, at maximum, 8 hours.

then the inequality xy ≤ 8 has sense.

Answer:

35

Step-by-step explanation:

The area of given figure is, 35 meter².

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

The figure is shown in figure.

Now, We know that;

⇒ Area of rectangle = Length × Width

So, The area of figure is,

⇒ 9 × 3 + (7 - 3) × 2

⇒ 27 + 4 × 2

⇒ 27 + 8

⇒ 35 meter²

401 minus 58 equals 343 (2nd aircraft)

Answer: 40 mph

Step-by-step explanation: let s = speed in traffic

(s+17) = out of traffic

:

Write a time equation; time = dist/speed

traffic time + normal speed time = 4 hrs

46%2Fs + 80%2F%28%28s%2B17%29%29 = 4

multiply by s(s+17) to cancel the denominators

46(s+17) + 80s = 4s(s+17)

46s + 782 + 80s = 4s^2 + 68s

126s + 782 = 4s^2 + 68s

Arrange as a quadratic equation on the right

2s^2 - 29s - 391 = 0

Use the quadratic formula a=2; b=-29; c=-391

I got a positive solution of

s = 23 mph in traffic

:

:

:

Check this by finding the actual times. Normal speed: 23 + 17 = 40 mph

46/23 = 2 hrs in traffic

80/40 = 2 hrs at normal speed

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

total time 4 hrs

0 = 4s^2 + 68s - 126s - 782

4s^2 - 58s - 782 = 0

simplify, divide by 2

so  the answer is 40mph

D

Step-by-step explanation:

Just came from the quiz

Answer:

for the line to have a constant slope, the difference of every y- ordinate with the last ordinate has to be equal

to check this, we will use the following formula

y4 - y3 = y2 - y1  

if both the LHS and the RHS are equal, the slope is constant and is irregular otherwise

5 - 8 = 7 - 3

-3 = 4

LHS ≠ RHS

Since LHS is not equal to RHS, the slope is NOT constant and hence keeps increasing or decreasing irregularly

Therefore, option 4 (Not a line) is correct

Answer:

it is not a constant line

Step-by-step explanation:

each x value increases by 1, but the y values are all over the place and are in no order.
