Each of 7 students reported the number of movies they saw in the past year. Here is what they reported.
17, 7, 13, 17, 7, 9, 10
Find the mean number of movies that the students saw.
If necessary, round your answer to the nearest tenth.
Answer:
11
Step-by-step explanation:
Answer:
11.4 (This is already rounded to the nearest tenth)
Step-by-step explanation
1.) Add all of them
17+7+13+17+7+9+10=80
2.) Divide the sum by how many numbers there are
In this case, there are 7, so 80/7 is 11.42...
3.) Get the answer
80.7 simplifies into 11.42 so rounded to the nearest 10th is 11.4.
Hope this helped. Good luck on your homework!

Answer:
[tex]y+4 = -\frac{1}{3} (x-1)[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope. Substitute the x and y values of the given points into the formula and solve:
[tex]m = \frac{(-5)-(-4)}{(4)-(1)} \\m = \frac{-5+4}{4-1} \\m = \frac{-1}{3}[/tex]
So, the slope is [tex]-\frac{1}{3}[/tex].
2) Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] into the formula.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{1}{3}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line, choose any one of the given points (it doesn't matter which one) and substitute the x and y values of it into the formula. (I chose (1,-4), as seen below). This gives the equation of the line in point-slope form.
[tex]y-(-4) = -\frac{1}{3} (x-(1))\\y+4 = -\frac{1}{3} (x-1)[/tex]

Answer:

Step-by-step explanation:
The location of point G which partitions the directed line segment from D to F into a 5:4 ratio is; x = 3
Division of a Line Segment
The formula for coordinate of a point that divides a line segment in a ration is given by;
x = (mx₂ + nx₁)/(m + n)
We are given the ratio 5:4
Thus m = 5 and n = 4
The endpoints of DF are D(-2) and F(7)
Thus;
x = ((5*7) + 4(-2))/(5 + 4)
x = 27/9
x = 3
Thus, the location of point G which partitions the directed line segment from D to F into a 5:4 ratio is x = 3

Colin predicted whether he got answers right or wrong in his 50 question exam.
He identified the 12 questions he thought he got wrong.
It turns out that Colin got 5 questions right that he thought he got wrong.
Colin also got a total score of 42 out of 50 in the test.
What is the percentage accuracy he had with predicting his scores
Answer:
92.86%
Step-by-step explanation:
Total questions, T = 50.
Colin thought 8 questions were right.
Colin got 5 questions right that he thought he got wrong.
Total score, s = 45.
So, actual number of questions which are wrong are 5.
Score according to him = 50 - 8 = 42.
Now, we know percentage accuracy is given by :
Therefore, percentage accuracy he had with predicting his scores is 92.86%.
The manager of the runners stop shoe store compares her sales from 2012 to those of 2013 last year she wolf 4235 pairs of sneakers and this year her sales ar 6122 pairs. What is the percent of increase in her sales to the nearest percent
Answer:
45%
Step-by-step explanation:
Percent increase in sales =(sales this year - sales last year) / sales last year x 100

While shopping at a clearance sale, Samantha finds a $60.00 dress on sale for 25% off. Samantha also has a 50% off
coupon. Which statement correctly summarizes her savings?
It seems most likely that ...
... Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction
_____
In the real world, it seems probable that Samantha will be offered the choice of using the coupon or the sale discount. If she chooses tht 50% coupon, her savings will be $30. If she chooses the marked sale discount, her savings will be $15.
The scenario above assumes she gets 50% off the sale price of $45, so saves $15+22.50 = $37.50 off the original price.
Answer:
The answer is B. (Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction.)

Major arc CBD measures 300 degrees. Which is the radian measure of its corresponding central angle? O 4 pie/3 O 5 pie/6 O 5 pie/3 O 11 pie/6
Answer:
[tex]\dfrac{5\pi}{3}[/tex]
Step-by-step explanation:
Given that,
Major arc CBD measures 300 degrees.
We need to find the radian measure of its corresponding central angle.
Radian measure is given by :
[tex]R=\dfrac{\pi}{180}\times d\\\\R=\dfrac{\pi}{180}\times 300\\\\R=\dfrac{5\pi}{3}[/tex]
So, the radian measure is [tex]\dfrac{5\pi}{3}[/tex].

∠C = 48°
Step-by-step explanation:
The two triangles are congruent by ASA. (The common side BD is between the angles marked congruent.) This means angles A and C have the same measure.
Angle A plus the two given angles will total 180°.
∠A = 180° -70° -62° = 48°
∠A = ∠C = 48°
