A random sample of Maxwell High School students showed that 7 out of every 12 students ride the bus to school . Maxwell High School has a total of 840 students . Based on the sample , how many students most likely ride the bus to school ?

Answer:

490 students

Step-by-step explanation:

Proportion of students who rode bus to school :

7 / 12 = 0.5833333

Given a sample size of 840 students ;

The likely Number of students who rode bus to school will be :

Sample size * proportion

840 * 0.5833333

= 490 students

Step-by-step explanation:

Answer:

28/53

Step-by-step explanation:

We need the cos of Q

therefore we'll use CAH (in SOH, CAH, TOA)

where CAH means

cos(angle)=adj/hyp

the side that adjacent to Q is 28

and the hypotonous (the oppsoite to the right angle) is 53

therefore cos(q)=28/53

Answer:

a.EF is longest

b.40 degree

c.140 degree

d.148 degree

e.BC,AC,BA

Step-by-step explanation:

Answer:

100% = 188

50% = 94

25% = 47

add 50% value and 25% value 141 or you can multiply 188 by .75

Step-by-step explanation:

hat is pretty simple first think 188 is the 100 percent

the 50 percentage is dividing by 2 the number or multiplying by 0.50 that is 50% so it's 94

to get 25 porcent you can't multiply by .25 or divide by 4

to get 75 porcent add the values of 50 and 25 percent or multiply 188 by .75

Answer:

40

Step-by-step explanation:

Find the other missing angle, which is supplementary to 100 first.

Supplementary angels are a sum of 180

The missing angle is 180-100 = 80

Now use that to find missing angle x

All angles in the triangle have a sum of 180

180 = 60+80+x

180-60-80=x

40 = x

Answer:

Paint set cost = 10.5 , Sketch book cost = 7 , Brush cost = 1.75

Step-by-step explanation:

Let the cost of paint set be = p

Cost of sketchbook 's' = (2 / 3) p

Cost of brush 'b' = 1/4th of s = 1 / 4 [ (2 / 3) p ] = (1 / 6) p

Total expenditure = Money bought - Money left = 23.25 - 4 = 19.25

Total expenditure = Cost of (pen + of sketchbook + of brush) = p + s + b

= p +  (2 / 3) p + (1 / 6) p  = 19.25 → p + 2p / 3 + p / 6 = 19.25

( 6p + 4p + p ) / 6 = 19.25 → 11p / 6  = 19.25 →  p = ( 19.25  x 6 ) / 11

p = 10.5 ; s = (2 / 3) p  = 2 / 3 (10.5) = 7 ; b = (1 / 6) p  = 10.5 / 6 = 1.75

Answer:

non proportional

Step-by-step explanation:

From the table;

0 = 0

25 = 5^2

100 = 10^2

Since the y values are the output and x is the input, hence;

y = x²

Since the equation is quadratic, hence the table is non proportional

p ≈ 2736

Answer: 3

Step-by-step explanation:

The number of getting the black hair color clients will be 4.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of samples

Given the of the clients who had their hair cut at Tanner's salon last month, 4 clients had black hair and 12 clients had hair in other colors.

The probability is:-

P = 4 / 12

The number of clients having black color hair is calculated as:-

Number = ( 4 / 12 ) x 12

Number =  4

Therefore, there will be 4 people getting black hair colors.

Answer:

(-√3/2., -1/2)

Step-by-step explanation:

This is a reflection in the line y = -x.

So x =  1/2 becomes y = -1/2

and y = √3/2  becomes x = -√3/2.

Answer:

So If you start with sinØ = .5

your calculator is programmed to always give the closest angle to 0, and that would be 30°

You probably used the cosine law to find the first angle. A suggestion is to always find the largest angle first. If that happens to be an obtuse angle, your calculator will find the correct angle.

Of course there can only be one obtuse angle in a triangle, so using the sine law for your second angle does not result in any problems

notice that in your solution 78 and 102 add up to 180 , and sin 78 = sin(180-78) = sin 102

I would have found angle S first, the largest angle always opposite the largest side.

7^2 = 5^2 + 4^2 - 2(5)(4)cosØ

40cosØ = -8

cosØ = -8/40 = -1/5

Ø = 101.537°

Now you can use the sine law and you will find the correct other angles.

Answer:

The answer is x=294 (B)

Step-by-step explanation:

Remember, all interior angles of a hexagon add to 720.

So add all the  given numbers first.

92+100+94+140+x= 720

426+x=720

-426 from both sides

x= 294
