Darryl was shopping for a new camera. He found one with an original price of
$125.00 and is marked 45% off. Sales tax for the item is 5.2%. What is the final
price of the camera, including tax?

Answers

Answer:

$72.33

Step-by-step explanation:

125 * 0.45 = 56.25

125 - 56.25 = 68.75 (marked off price)

68.75 * 1.052 = 72.33 (add sales taxes and round off)

Final price $ 72.33

Luis's bowling scores were 195, 194, 191, 190, 238, and 192. Which measure (median, mean, mode or range) BEST describes Luis's bowling score? EXPLAIN your answer.

Answers

Step-by-step explanation:

The given data is :

195, 194, 191, 190, 238, and 192

Mean = (sum of observations)/(total no. of observations)

[tex]\text{Mean}=\dfrac{195+194+191+190+238+192}{6}\\\\=200[/tex]

So, the mean is the best measure. Also, w can find median as follows.

arranging in order : 190,191,192, 194, 195,238

Here, n = 6

[tex]\text{Median}=\dfrac{\dfrac{n}{2}^{th}+(\dfrac{n}{2}+1)^{th}}{2}\\\\\text{Median}=\dfrac{\dfrac{6}{2}^{th}+(\dfrac{6}{2}+1)^{th}}{2}\\\\=\dfrac{3^{th}+4^{th}}{2}\\\\=\dfrac{192+194}{2}\\\\=193[/tex]

Hence, this is the required solution

Find the slope of the in line containing the ordered pairs. (7 marks)
a. A(2,-5), B(-2,6)

Answers

Answer:

= -11/4

Step-by-step explanation:

To find the slope given two points

m = ( y2-y1)/(x2-x1)

   = (6 - -5)/(-2 -2)

   = (6+5)/(-2-2)

    = 11/-4

    = -11/4

Answer:

-2.75 (-2 3/4)

Step-by-step explanation:

you can do rise of a run whenever you have two points so you have 6-(-5)/-2-2 and solve so -11/4 and that equals -2.75.

The class average on a math test was an 82 with a standard deviation of 5. If the 
data is normally distributed, which statements are true?

1. A student scoring a 74  would have a z -score of -1.6.
2. About 68% of the students  scored below an 87.
3. A z-score of 2.6 would be a test 
score of 95.
4. About 16% of the class  scored a 77 or below.
45. About 25% of the class  scored above a 92.

Answers

Answer:

Option 3 and 4.

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation[/tex]

Given that mean (μ) = 82, standard deviation (σ) = 5

1) For x = 74:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{74-82}{5} =-1.6[/tex]

Option 1 is incorrect

2) For x < 87

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{87-82}{5} =1[/tex]

From the normal distribution table, P(x < 87) = P(z < 1) = 0.8413 = 84.13%

Option 2 is incorrect

3) For x = 95:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{95-82}{5} =2.6[/tex]

Option 3 is correct

4) For x < 77

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{77-82}{5} =-1[/tex]

From the normal distribution table, P(x < 77) = P(z < -1) = 0.16 = 16%

Option 4 is correct

5) For x > 92

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{92-82}{5} =2[/tex]

From the normal distribution table, P(x > 92) = P(z > 2) = 1 - P(z < -2) = 1 - 0.9772 = 0.0228 = 2.28%

Option 5 is incorrect

In right triangles one of the angles will always be 90 degrees.

So if you had a right triangle with one right angle, a number, and a number, they always have to add up to 90 degrees as well, because a triangle is always 180 degrees

so

At the dress shop, Sherry is building buttons into packages. She has reached the 867 th button and is packing the 34 th package when she is asked to take her lunch break . She needs to note the number of buttons that are in the package so when she returned she will continue she will continue . How many buttons does package 34 contain? dont send in file explain plz​

Answers

Answer:

9 buttons in package 34

Step-by-step explanation:

There are 26 buttons in each box.

26 * 33 = 858 for the first 33 full boxes

867 - 858 = 9 buttons in the 34th box

B = buttons per box

33*B<867 --> B < 26.27

34*B>867 --> B > 25.5

So 25.5 < B < 26.27, therefore B = 26 buttons per box

Carly is buying deli meat for her lunches this week. Turkey is on sale for $5.80 per pound. If Carly buys 1.25 pounds of turkey, how much money does she spend?

Answers

Answer:

Carly will have to spend $7.25

Step-by-step explanation:

We know that:

1 pound of turkey = $5.80

To find how much 1.25 pounds of turkey will cost, multiply:

5.80 x 1.25 = 7.25

Therefore, 1.25 pounds of turkey will cost $7.25

I really hope this helps!

Answer:

x = 11

Step-by-step explanation:

The two angles form a straight line so they add to 180

4x+15 + 11x = 180

Combine like terms

15x+15 = 180

Subtract 15 from each side

15x+15-15 = 180-15

15x = 165

Divide by 15

15x/15 =165/15

x = 11

Given:

Cards labelled 1, 3, 5, 6, 8 and 9.

A card is drawn and not replaced. Then a second card is drawn at random.

To find:

The probability of drawing 2 even numbers.

Solution:

We have,

Even number cards = 6, 8

Odd numbers cards = 1, 3, 5, 9

Total cards =  1, 3, 5, 6, 8 and 9

Number of even cards = 2

Number of total cards = 6

So, the probability of getting an even card in first draw is:

[tex]P_1=\dfrac{\text{Number of even cards}}{\text{Number of total cards}}[/tex]

[tex]P_1=\dfrac{2}{6}[/tex]

[tex]P_1=\dfrac{1}{3}[/tex]

Now,

Number of remaining even cards = 1

Number of remaining cards = 5

So, the probability of getting an even card in second draw is:

[tex]P_2=\dfrac{\text{Number of remaining even cards}}{\text{Number of remaining total cards}}[/tex]

[tex]P_2=\dfrac{1}{5}[/tex]

The probability of drawing 2 even numbers is:

[tex]P=P_1\times P_2[/tex]

[tex]P=\dfrac{1}{3}\times \dfrac{1}{5}[/tex]

[tex]P=\dfrac{1}{15}[/tex]

Therefore, the probability of drawing 2 even numbers is [tex]\dfrac{1}{15}[/tex]. Hence, the correct option is (b).
