Answer:

  • If you score a 0% on your exam, you get 53.9% as your overall grade
  • If you score 100% on your exam, you get 83.9% as your overall grade

====================================================

Explanation:

Your final is worth 30% of your grade, so the other 70% is what you've already done so far

The expression below

0.30x + 0.70*0.77

represents what your final grade would be in decimal form. We multiply the weights 0.30 and 0.70 with each of their corresponding grade value.

The x represents the decimal form of the final exam score.

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

Let's say you get a 0% on the final. That would mean x = 0 and

0.30x + 0.70*0.77

0.30*0 + 0.70*0.77

0.539

So you'd end up with a 53.9% as the overall grade.

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

Now let's say you get 100% on the final. We plug in x = 1 since it's the decimal form of 100%

So,

0.30x + 0.70*0.77

0.30*1 + 0.70*0.77

0.839

You would end up with a 83.9% as the overall grade.

Answer:

<u>45°</u>

Step-by-step explanation:

From the diagram :

  • ∠AOC = ∠AOB + ∠BOC
  • 96 = 9x - 75 + 8x - 67
  • 17x - 142 = 96
  • 17x = 238
  • x = 238/17
  • x = 14

Finding ∠BOC :

  • ∠BOC = 8x - 67
  • ∠BOC = 8(14) - 67
  • ∠BOC = 112 - 67
  • ∠BOC = <u>45°</u>

For the function f(x) = 2 - 3x, find f(-4). Options are in the picture.
Kitty [74]
You just have to plug in -4 into
f(x) = 2 - 3x
This implies that,
f( - 4) = 2 - 3( - 4)


f( - 4) = 2  + 3(4)
f( - 4) = 2 + 12
f( - 4) = 14

Complete the chart to find the mean, variance, and standard deviation. Remember to use commas and round numbers to the nearest t
vitfil [10]

Answer: The mean of the data is 433.75, variance of the data is 99667.19 and the standard deviation of the data is 315.7011.

Explanation:

The given data is 900, 35, 500 and 300.

The number of observation is 4.

Formula of mean is,

\text{Mean}=\frac{\text{Sum of observations}}{\text{Number of observations}}

\bar{X}=\frac{900+35+50+300}{4} =433.75

The formula of variance is given below,

\sigma^2=\frac{1}{n}\sum{(X-\bar{X})^2}

\sigma^2=\frac{398668.75}{4}

\sigma^2=99667.19

The variance of the data is 99667.19

\sigma=\sqrt{99667.19}

\sigma=315.7011

The standard deviation of the data is 315.7011.

The other information or values of given chart is shown in the attached table.

Answer:

I think it would be 65 degrees

Step-by-step explanation:

If the side of Line q and line k is 115 degrees and its the same for line m and line k, then all you have to do is take 180 and subtract 115 from it to get the other side of the angle.

Graph the function y = |8 - 2x| + 3. Which is a point on the function? (6.2, 7.4) (7.8, 11.2) (8.6, 6.8) (9.6, 7.3)
Fiesta28 [93]
For this case we have the following function:
 y = | 8 - 2x | + 3&#10;
 The first thing you should do is graph the function to see the behavior.
 When observing the graph (in the attached image) we observe that the following point belongs to the graph:
 (6.2, 7.4)&#10;
 To prove it, let's evaluate the point in the function:
 7.4 = l 8 - 2 (6.2) l + 3&#10;&#10;7.4 = l 8 - 12.4 l + 3&#10;&#10;7.4 = l -4.4 l + 3&#10;&#10;7.4 = 7.4
 The equation is fulfilled and therefore the point belongs to the graph.
 Answer:
 
(6.2, 7.4)
