There are twenty classes at Northwestern Middle School and twenty classes at Southeastern Middle School. The number of students in each class at each school is shown in the dot plots below.

Number of Students in Each Class at Northeastern Middle School
A dot plot. A number line going from 20 to 29 labeled Number of Students. There are 3 dots above 20, 5 above 21, 7 above 22, 4 above 23, 1 above 24, and 0 above 25, 26, 27, 28, and 29.

Number of Students in Each Class at Southeastern Middle School
A dot plot. A number line going from 20 to 29 labeled Number of Students. There is 1 dot above 20, 2 above 21, 2 above 22, 4 above 23, 3 above 24, 2 above 25, 2 above 26, 2 above 27, 1 above 28, and 1 above 29.

Michela says that the modes of the two data are the same so the median and mean must also be the same. What is Michela’s error?
The modes are not the same.
The means and medians are not the same.
Only the modes and the medians are the same.
Only the modes and the means are the same.

Answer:

6 Oranges and 2 bottles of juice.

Step-by-step explanation:

For the amount of oranges: 18÷3=6 (take 1/3 of 18).

For the bottles of of Juice: 18÷9=2 (take 1/9 of 18).

in this question, if the numerator is 1, then just divide the number of girls by the denominator (eg. 3 and 9 in this case).

There are six oranges and two bottles of juice will she needs for all 18 girls.

In mathematics, divides left-hand operands into right-hand operands in the division operation.

For example 4/2 = 2

There are the total number of girls is 18. Each girl will eat 1/3 of an orange and one serving of juice, or 1/9 of the amount in a bottle.

To determine the number of oranges and the bottles of juice.

We have to divide the number of girls by the denominator (eg. 3 and 9 in this case).

For the number of oranges:

1/3 of 18

18 ÷ 3

18 / 3 = 6

For the bottles of Juice:

1/9 of 18

18 ÷ 9

18 / 9 = 2

Hence, there are six oranges and two bottles of juice will she needs for all 18 girls.

Answer:

no

Step-by-step explanation:

The function f(x)=x2 is not one-to-one because f(2) = f(-2). Its graph is a parabola, and many horizontal lines cut the parabola twice. The function f(x)=x 3, on the other hand, IS one-to-one. If two real numbers have the same cube, they are equal.

Answer:

a) 6 ways

b) 6 ways

Step-by-step explanation:

a) for all of the letters

for the first letter, we have 3 options

for the second, we have 2 options

for the third, we have 1 option

So the number of options will be;

3 * 2 * 1 = 6

b) for the first, we have 3 options, for the second, we have 2 options

so the number of options will be 3 * 2 = 6 options

Instead of ( 1 - 4) all satisfy the equation

Answer:

45 pages in 1 hour

Step-by-step explanation:

Find the unit rate by dividing the number of pages by the number of hours

135/3

= 45

This means he can read 45 pages in 1 hour.

The unit rate is 45 pages in 1 hour.

id k i got 4x + 5y=40

Step-by-step explanation:

Answer:

6x+2y=-78

Step-by-step explanation:

8x-3y=-70

-2x+5y=-8

6x+2y=-78

Answer:

(-11, -6).

Step-by-step explanation:

8x-3y=-70

-2x+5y=-8     Multiply this equation by 4:

-8x+20y=-32

Now add this last equation to the first equation:

17y = -102   - we see that we have eliminated x.

y = -102/17

= -6.

Now plug y=-6 in the first equation to get x:

8x-3(-6)=-70

8x =-70 -18

8x =-88

x = -11.

Answer:

y =  x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y =  x + 7 ← is in slope- intercept form

with slope m =

Parallel lines have equal slopes

line M crosses the y- axis at (0, 3) ⇒ c = 3

y =  x + 3 ← equation of line M

Step-by-step explanation:

Just divide 48 by 12 so as to get the temperature dropped in each hour

Solution :

It is given that the distance between the two lights is 30 feet.

The angle of elevation of the upper light from the boat, ∠ ABP = 32 degree

The angle of elevation of the lower light from the boat, ∠ ABQ = 14 degree

∴ ∠ PBQ = ∠ ABP - ∠ ABQ

              = 32 - 14

              = 18 degree

In triangle PAB

∠ PAB = 180 - (90 + 32)

           = 58 degree

Similarly in triangle AQB

∠ AQB = 180 - (90 + 14)

           = 76 degree

Now considering triangle PBQ and applying the sine theorem,

[tex]$\frac{PQ}{\sin 18}=\frac{BQ}{\sin 58}$[/tex]

we know PQ = 30 feet

∴ [tex]$BQ =\frac{\sin 58}{\sin 18} \times 30$[/tex]

        = 82.33 feet

Again taking the right triangle ABQ and applying sine theorem,

[tex]$\frac{BQ}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

[tex]$\frac{82.33}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

∴ [tex]$AB = 82.33 \times \sin 76$[/tex]

         = 79.88 ft

         = 80 feet

Answer:

25% markup

Step-by-step explanation:

they bought 200 shirts for 1600, which is 8$ per shirt

if they sell then at 10$ they get 2 dollars profit.

if you do 2/8 you get 25%

Also 1/4 of 8$ is 2$ and that is what your profit is.

Answer:

25%

Step-by-step explanation:

Cost of one short:

1600 : 200 = $8

8 + 8(x/100)= 10

800 + 8x= 1000

8x = 200

x = 25 %

AB = sqrt 74 = 8.602

Step-by-step explanation:

simple:

a^2+b^2=c^2

5^2+7^2=74

ab=sqrt 74

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(8−3)2+(2−9)2(8-3)2+(2-9)2

= √52+(−7)252+(-7)2

= √25+4925+49

= √7474 = 8.6023

Distance between points (3, 9) and (8, 2) is 8.6023
