Suppose the students who scored 85 and 90 on the math test take the test again and score 95 how manu stars would you have to add to the picture graph next to 95 Key each star equals 4
Math test scores
100 / // / / 20 people scored 100
95 / / / 12 people scored 95
90 / / / | 14 people scored 90
85/ 4 people scored 85

Answers

In this question, each star equal to 4 students. If the people on 85 and 90 take the test again that means their number should be 14+4 people= 18 people. 
If they all get 95, then it means we need to add 18 people to the 95 graph. The number of stars would be: 18 people / (4people/stars)= 4.5 stars

If you add the stars graph it will be easier. It should be clear that 85 will have 1 stars and 90 have 3.5 stars. Adding them up will be 1 stars + 3.5 stars= 4.5 stars

12 divided by the sum of h and 2

Write it in algebraic expression

Answers

12 divided by the sum of h and 2....

12 / (h + 2)
Since h and 2 together is a sum, and sum is what you get when you add two or more number/variables, add h and 2 for the expression h+2.
Since 12 is being divided by (h + 2), put the 12 above the h+2. This gives you the following expression:
(12)/(h+2)

2(x - 1) + 3(1 - 2x) = 5 - x




​

Answers

Answer:

x = -4/3

Step-by-step explanation:

2(x-1) +3(1-2x) = 5-x

Distribute

2x-2 +3 -6x = 5-x

Combine like terms

-4x +1 = 5-x

Add 4x to each side

-4x+4x +1 = 5-x+4x

1 =5+3x

Subtract 5 from each side

1-5 =5-5 +3x

-4 = 3x

Divide each side by 3

-4/3 = 3x/3

-4/3 =x

Answer:

1-5 =5-5 +3x

-4 = 3x

Divide each side by 3

-4/3 = 3x/3

-4/3 =x

8,5.7,1,3,2,4,6 is the correct order

Step-by-step explanation:

1. There are 10 numbers from 1 to 10 , thus there are 10 possible outcomes.

Determine the number of favourable outcomes for each event:

Number greater than 0 : 10 favourable outcomes ( 1,2,3,4,5,6,7,8,9,10)

Even number : 5 favourable outcomes ( 2,4,6,8,10)

Number is at least 2 : 9 favourable outcomes ( 2,3,4,5,6,7,8,9,10)

Number is at most 0 : 0 favourable outcomes ( as none of the integers from 1 to 10 are at most  0 )

Number is divisible by 3 : 3 favourable outcomes ( 3, 6,9)

Number is divisible by 5 : 2 favourable outcomes ( 5, 10)

Prime number : 4 favourable outcomes ( 2, 3, 5, 7 )

Number less than the greatest prime number : 6 favourable outcomes ( 1, 2,3,4,5,6 as 7 is the greatest prime number from the numbers of 1 to 10 )

2. The more favourable outcomes correspond with an event, the more likely the event is to happen. Thus the number is at most 0 is the least likely and the number greater than 0 is the most likely.  

Let us then number the events from least likely to most likely:  

Number greater than 0: 8

Even number: 5

Number is at least 2: 7

Number is at most 0:1

Number is divisible by 3: 3

Number is divisible by 5: 2

Prime number 4

Number less than the greatest prime number: 6  

So the order is 8,5.7,1,3,2,4,6
