The circle graph describes the distribution of preferred music from a sample of 400 randomly selected middle school students.
a circle graph titled preferred music, with five sections labeled rock 13 percent, hip hop 25 percent, pop 35 percent, classical 13 percent, and jazz 14 percent
Which of the following conclusions can we draw from the circle graph?
Pop is the preferred music for 35 students.
Jazz is the preferred music for 56 students.
Together, Hip Hop, Rock, and Jazz are the preferred music for less than half the students.
Together, Hip Hop and Pop are the preferred music for 260 students.
Answer:
Step-by-step explanation:
(i) Number of people who are into classical music =10%
10% of pie chart =20 people.
1% ⇒ 10/20 ×100
and 100% ⇒ 10/20 ×100 × 100/ 100
⇒200 people.
(ii) Light chart represent maximum number as it is 40% of total. ∴ Light music is liked by maximum people.
(iii)
Number of CD's of classical music ⇒ 100/10 × 1000(10%) =100
umber of CD's of semi classical music = 100/20 × 1000(20%) =200
just like that 30% is 300, 40% is 400.

Haven't done this kinda problem in a while but I got 4/3 cm/s
Step-by-step explanation:
Using the coordinates given i put them into the formula:
y1 - y2
m=_________
x1 - x2

Step-by-step explanation:
Triangle ABC is a scale drawing of Triangle XYZ, as shown.
Based on the information shown in these triangles, which of the following is a true statement?
A) The length of side XZ is 11.5.
B) The length of side XZ is 28.
C) The measure of angle A is equal to the measure of angle Z.
D) The measure of angle A is not equal to any of the angle measures of Triangle XYZ.
Answer: B the side length of XZ is 28
Step-by-step explanation:
to find the scale factor, one of the methods is to divide the side length of one triangle by the same side length of the other triangle.
for example with this problem, the length of XY is 42 while side length AB is 12. 42/12 is 3.5. we know that the side length that corresponds with XZ is 8 so multiply it by 3.5 to get the answer of 28.
Answer:
B
Step-by-step explanation:
Since we know that triangle XYZ is a scale model of ABC then if we find the amount XYZ is bigger then ABC then we can find the answer. Line CB is the corresponding line to ZY and ZY is 3.5x greater then CB. Apply the same logic to AC and we get 8*3.5=ZX 8*3.5=28 so ZX=28.

(22 - 4) / 6
The answer would be 3 miles on each of the six days
Answer:
In a week we have 7 days.
On the first day, Clare runs 4 miles.
On the other six days, she runs the same distance, let's call it D.
In total, she runs 22 miles.
Then:
4mi + 6*D = 22 mi
6*D = 22mi - 4mi = 18mi
D = 18mi/6 = 3mi.
Then the other 6 days, Clare runs 3 miles

-2 1/3 ÷ 4 2/3
Please help, I will grant the 1st person to answer correctly brainliest.
Answer: -1/2
Step-by-step explanation:
1. We know that -2 1/3 is also equal to -7/3, because we can multiply the denominator by the main number, and add the numerator.
2. We can do the same with 4 2/3, which would be 14/3.
3. Now, we are left with -7/3 divided by 14/3.
4. To make this easier, we can flip flop the 14/3 so we can multiply instead of divide, which leaves us with -7/3 x 3/14.
5. -7/3 x 3/14 = -21/42
6. We can simplify this to -1/2.

create equivalent ratios by completing a ratio table for each. 1. 7 to 5 ( using multiplication), 2. 50:20 ( using division), 3. 3/4 (using multiplication), 4. 18:48 ( using division)
ASAP
Step-by-step explanation:
7 : 5
[tex] \binom{7 \: 14 \: 21 \: 28 \: 35}{5 \: 10 \: 15 \: 20 \: 25} [/tex]
50 : 20
[tex] \binom{50 \: 25 \: 5}{20 \: 10 \: 2} [/tex]
3 : 8
[tex] \binom{3 \: 6 \: 9 \: 12 \: 15 \: 18}{8 \: 16 \: 24 \: 32 \: 40 \: 48} [/tex]
18 : 48
[tex] \binom{18 \: 9 \: 6 \: 3}{48 \: 24 \: 16 \: 8} [/tex]
Ratios must always remain proportional;
Whenever you multiply or divide one part by a number, you must do the same to the other part/s;
When it comes to division, you can divide by all common factors
