Answer:
the comedy films, action and horror is 14, 49 and 7 respectively
Step-by-step explanation:
The computation of each one dvds is as follows;
Total dvds is 70
Now the ratio of comedy films to action to horror is 2:7:1
So the total of 10
Now the each one dvds is
For comedy flms
= 70 × 2 ÷ 10
= 14
For actions
= 70 × 7 ÷ 10
= 49
For horror
= 70 × 1 ÷ 10
= 7
Hence the comedy films, action and horror is 14, 49 and 7 respectively

Answer:
x=3
Step-by-step explanation:
15+17+5x = 47
if you add 15 and 17 just to make it easier, you get....
32+5x = 47
what I did next was minus 32 from each side.
so you are left with....
5x = 15
divide each side by 5 and you get
x = 3
you can go back and make sure that- that is right by doing 15+17=32 and
5x3 = 15 then add them together, 32+15 = 47
Write an expression that has three terms, two diffrent variables, and one constant.
Answer:
x + y + 1
or
xy + y² + 2
or
x² + y² - 1
or
a²b + b³ + 3
Step-by-step explanation:
You can use x and y as the two variables. Then add them to make is x + y (this is already two variables and two terms). Add a constant, say 1. So x + y + 1, now we have three terms with two different variables and one constant.
Or you can also make it xy + y² + 2 or x² + y² - 1 by adding exponents to each of the variable.
You can choose one from the above or you can make your own (it depends on you).

Answer: x = 32°
Step-by-step explanation:
(3x - 4) + (3x - 8) = 180
3x - 4 + 3x - 8 = 180
6x - 12 = 180
6x - 12 + 12 = 180 + 12
6x = 192
6x ÷ 6 = 192 ÷6
x = 32

A random sample of 400 CLU students is taken. 395 students reported that Econ 311 was their favorite class. Calculate the margin of error for a 96% confidence interval.
Answer:
The margin of error for a 96% confidence interval is of 0.0114 = 1.14%.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
For this problem, we have that:
[tex]n = 400, p = \frac{395}{400} = 0.9875[/tex]
96% confidence level
So [tex]\alpha = 0.04[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.04}{2} = 0.98[/tex], so [tex]Z = 2.056[/tex].
Calculate the margin of error for a 96% confidence interval.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 2.056\sqrt{\frac{0.9875(0.0125)}{400}}[/tex]
[tex]M = 0.0114[/tex]
The margin of error for a 96% confidence interval is of 0.0114 = 1.14%.

Mr. Hammond is the volunteer coordinator for a company that puts on running races. Last year, the company organized 7 short races and 8 long races, which required a total of 804 volunteers. This year, the company organized 11 short races and 5 long races, which required 688 volunteers in total. How many volunteers does each type of race require?
Answer:
28 short race volunteers
76 long race volunteers
Step-by-step explanation:
Let :
Short races = a
Long races = b
LAST YEAR:
7a + 8b = 804 - - - - (1)
THIS YEAR:
11a + 5b = 688 - - - (2)
Multiply (1) by 5 and (2) by 8
35a + 40b = 4020
88a + 40b = 5504
Subtract
-53a = - 1484
a = 1484 / 53
a = 28
Put a = 28 in equation (1)
7(28) + 8b = 804
196 + 8b = 804
8b = 804 - 196
8b = 608
b = 76
28 short race volunteers
76 long race volunteers
32 athletes are going camping for the weekend. Three athletes can sleep in one tent. What is the minimum number of tents that will be needed?
Minimum number of tents are 11.
Here,
32 athletes are going camping for the weekend.
3 athletes can sleep in one tent.
We have to find the minimum number of tents.
What is Number system?
A system of writing to express number is called Number system.
Now,
Number of athletes = 32
Number of athletes in one tent = 3
Hence, Minimum number of tents = 32 ÷ 3
We get 11 tents for 32 athletes.
Therefore, Minimum number of tents are 11.

Angle ABC is taken by a dilation with the center P and scale factor 3 to angle A'B'C'
The measure of angle ABC is 21 degrees. What is the measure of angle A'B'C'?
Answer: 21
Step-by-step explanation: We are given that angle ABC is dilated with center P.
Scale factor=3
Angle A'B'C' is formed after dilation of angle ABC.
Dilation: when a figure is dilated by scale factor a then, the figure shape does not change.
After dilation, the size of figure changes.
The initial figure and the figure obtained after dilation are similar in shape.
When two figures are similar then , the angles of one figure are congruent to its corresponding angles in other figure and ratio of their corresponding sides are equal.
The measure of angle ABC=21'
After dilation by scale factor 3 then, the measure of angle A'B'C' remains=21'
Because the shape does not change in dilation transformation.

A housefly can fly about 6.4 feet per second. At this rate, how far can it fly in
25 seconds ?
Answer:
1 second = 6.4 feet
25 seconds = 6.4 * 25 = 160 feet
Answer:
160ft
Step-by-step explanation:
So we already know the unit rate, all we need to do is find how many times the fly can go 6.4 feet in 25 seconds, so our equation is:
25 x 6.4 = 160
So our housefly can fly 160 feet in 25 seconds
