Answer:
The correct solution is "3".
Step-by-step explanation:
Given that:
Mean of distribution,
[tex]x = 49[/tex]
Standard deviation,
[tex]\sigma=5[/tex]
Score,
[tex]\mu=25[/tex]
Let the score in an exam be "x".
Now,
The z-score will be:
= [tex]\frac{x-\mu}{\sigma}[/tex]
On putting the values, we get
= [tex]\frac{40-25}{5}[/tex]
= [tex]\frac{15}{5}[/tex]
= [tex]3[/tex]

I. Collect data from several fast-food chains on the number of fat calories and grams of saturated fat in menu items. A record at least 12 ordered pairs of (fat calories, grams of saturated fat). Organize your data in a table.
II. Make a scatter plot of the data on graph paper. Be sure to label the axes and use an appropriate title for the graph.
You may wish to use a graphing calculator, spread sheet, or other technology resource (such as the graphing utility link below) to aid you in graphing.
III. Draw a trend line for the scatter plot. Use the following scatter plot of the ordered pairs (fat grams, total calories) as an example.
IV. Calculate the slope of the trend line. (Choose two points on the line and find vertical change over horizontal change.)
Note: Graphing calculators and spread sheets have features with which to draw trend lines and determine the equation. You may choose to use one of these options. If you use technology, indicate what steps were taken to arrive at your equation.
V. Using the slope and y-intercept, write the equation of the trend line ( y = mx + b).
VI. Choose a "calories from fat" value that is not in your collected data set and that is at least 10 fat calories away from any collected value. Use the equation calculated in step V to predict the number of fat grams in an item having that number of fat calories. Be sure to show your work.
VII. Search for an item in a fast-food menu having the same number of fat calories as the one you chose above. (If you cannot find the exact value, get as close as you can.) Compare the calculated value from step VI to this actual value. Explain why (or why not) you would have expected your prediction (calculated value) to be close to the actual value.
Answer:
IV. Two points: (21,430), (29,541)
29/541 - 21/430, 541-430 = 111, 29 - 21 = 8 ,
now we have 111/8 which equals 13.87, or rounded to 14the slope is 14
V. the equation is y = 14x + 94
VI. If an item has 600 calories: y = 14x + 94, substitute for y, 600 = 14x + 94, 600 - 94 = 506, 506 divided by 14 = 36.14. There are approximately 36 grams of fat in an item that has 600 calories.
VII. In my estimate, I calculated that there would be approximately 36 grams of fat in a 600 calorie item. When compared to a menu item of 600, there was only about 29 grams of fat. There are many factors that can cause such a guessed difference in between these items' grams of fat. My estimate for one was expecting a higher content of fat than what is actually advertised on this fast food menu. The fast food items that I include in my scatter plot may have all had a higher calories to fat grams ratio in general compared to this singular menu item. The location of these fast food restaurants influences the produce, meat, and other ingredients that all add to the grams of fat in the item served on the menu.

If you had $1000 and it earned 5% interest for one year, you would have earned __________in interest that year.
Answer:
Simple interest = P × R × T/ 100
simple interst = 1000 × 5 × 1 / 100
simple interst = 10 × 5 × 1 = 50
one year interst = $ 50

Find the values of x, y, and z.
Answer:
x = 7
y = 26
z = 6
Step-by-step explanation:
First, we can use vertical angles to say the angle with measure 10x + 6 is equal to the angle with measure 16x - 36. Because of this, we can set up an equation to solve for x:
10x + 6 = 16x - 36
6 = 6x -36
6x = 42
x = 7
Next, we can realize the angle 10x + 6 and 4y are supplementary and add up to 180 because they form a straight line. We can set up and solve the equation:
10x + 6 + 4y = 180
We found x = 7, so we can plug that in:
70 + 6 + 4y = 180
76 + 4y = 180
4y = 104
y = 26
Now, we can realize that the angle 4y and 16z + 8 are vertical angles; this gives us the equation:
4y = 16z + 8
We found that y = 26, so we can plug that in to get:
104 = 16z + 8
16z = 96
z = 6

Need help with 5, 6, 7, 8 thank you !!!
Answer:
5. B) x = 7
6. D) 35°
7. C) 67°
8. A) 142°
Step-by-step explanation:
5. Inscribed angle of a semicircle is equal to 90°. Therefore,
16x - 22 = 90
Solve for x
16x - 22 + 22 = 90 + 22
16x = 112
16x/16 = 112/16
x = 7
6. Recall: inscribed angle = ½(intercepted arc)
3x - 1 = ½(8x - 26)
2(3x - 1) = 8x - 26
6x - 2 = 8x - 26
Collect like terms
6x - 8x = 2 - 26
-2x = -24
-2x/-2 = -24/-2
x = 12
m<LMN = 3x - 1
Plug in the value of x
m<LMN = 3(12) - 1 = 36 - 1
m<LMN = 35°
7. Recall: inscribed angle = ½(intercepted arc)
Therefore,
4x + 28 = ½(11x - 1)
2(4x + 28) = 11x - 1
8x + 56 = 11x - 1
Collect like terms
8x - 11x = -56 - 1
-3x = -57
-3x/-3 = -57/-3
x = 19
Arc BC = 360° - (Arc AC + Arc AB) (Full circle)
Substitute
Arc BC = 360 - (11x - 1 + 85)
Plug in the value of x
Arc BC = 360 - (11*19 - 1 + 85)
Arc BC = 360 - (209 - 1 + 85)
Arc BC = 360 - 293
Arc BC = 67°
8. Inscribed angles intercepted by the same arc are equal. Therefore,
8x - 41 = 5x + 1
Collect like terms
8x - 5x = 41 + 1
3x = 42
3x/3 = 42/3
x = 14
5x + 1 = ½(arc PS) => inscribed angle = ½ of intercepted arc
2(5x + 1) = arc PS
Plug in the value of x
2(5*14 + 1) = arc PS
2(70 + 1) = arc PS
2(71) = Arc PS
Arc PS = 142°

solve this parallelogram angle
Answer:
103
Step-by-step explanation:
angles formed on the same line of a parallelogram are supplementary angles
( the angle with the measure of 77 degrees and the angle labeled "x" are formed on the same line which means they are supplementary )
supplementary angles add up to equal 180
hence, 77 + x = 180
180 - 77 = 103
Hence, x = 103
Answer:
103°
Step-by-step explanation:
Hint :sum of angles of quadrilateral = 180°Simplify:77° + x° = 180°
x° = 180° - 77°
x° = 103

in circle k secant pec intersects chord bkd at f if ae is congruent to ab the measure of arc ed is 32 and arc bc: arc cd is 2:1 then find the measure of angle p
Answer:
60°
Step-by-step explanation:
Diameter of circle = BD ; Hence, BD = 180°
Arc BC : CD = 2 : 1
BD = BC + CD = 180
BC = 2/3 * 180 = 120°
CD = 1/3 * 180 = 60°
Since ED = 32°
BE = 180 - 32 = 148°
BA = AE
BE = BA + AE
BA = AE = 148° / 2 = 74°
Arc ABC = BA + BC
Arc ABC = 74° + 120 = 194°
P = (Arc ABC - AE) / 2
P =(194 - 74) / 2
P = 120 / 2
P = 60°
