Answer In Explanation

Step-by-step explanation:

O More Than Half Of The Students Scored 81 Or Better

O The Same Number Of Students Scored Between 81 And 90 On The Test As     Scored Between 61 And 80

-The Last One Is Confusing Because It Doesn't Say 71-80

Answer 2

Options (B) and (D) are true statements that describe the data in the histogram are the correct answers.

What is a histogram?

A histogram is a visual way to display frequency data using bars. It is a chart that shows frequencies for intervals of values of a metric variable. It is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.

For the given situation,

The histogram shows the scores on a recent science test.

We need to check the options, which statements describe the data.

Option A: Only two students scored less than 71 on the test.

There are four students scored less than 71.

So option A is false.

Option B: More than half of the students scored 81 or better on the test.

Students scored more than 81 = [tex]16+8[/tex]

⇒ [tex]24[/tex]

Total number of students = [tex]40[/tex]

Half of the students = [tex]\frac{40}{2}[/tex]

⇒ [tex]20[/tex]

Thus, [tex]24 > 20[/tex]

So option B is true.

Option C: More students scored between 91 and 100 on the test than scored between 71 and 80.

Students scored between 91 and 100 = [tex]8[/tex]

Students scored between 71 and 80 = 12

⇒ [tex]8 < 12[/tex]

So option C is false.

Option D: The same number of students scored between 81 and 90 on the test as scored between 61 and 80.

Students scored between 81 and 90 = [tex]16[/tex]

Students scored between 61 and 80 = [tex]4+12[/tex]

⇒ [tex]16[/tex]

Thus, [tex]16=16[/tex]

So, option D is true.

Option E: There were 12 students who scored 80 on the test.

The score range is between 71 to 80. So we could not predict the number of students who score 81.

So option E is false.

Hence we can conclude that options (B) and (D) are true statements that describe the data in the histogram are the correct answers.

Step-by-step explanation:

Well, we know the scale is 1 1/2 inches to 4 feet and that one side length of the scaled drawing sqaure is 3 inches, so . . .

3/1 1/2 (3 divided by one and one-half)

to get: 2

Then multiply it by the scale factor of 4

2*4= 8

But remeber, this is only ONE side of the garden, so multiply this by 4

8*4=32  

Next we want to see the number of links it takes to build the garden

Since one link measures 2 2/3 feet you have to divide

32/ 2 2/3 (32 divided by two and two-thirds)

85%

Step-by-step explanation:

51/60 is 85%

It’s 15% because 60-9 = 51 so now you have to find out what percent 51 is out of 60 and it was 85% now you have to find out how much you took off so 100% ( the beginning amount) - 85% ( the percent left after the decrease) = 15%

Children get a 15% discount on tickets to an amusement park. Jun had a coupon for 5% off any two tickets. He used the coupon for himself and his 4-year-old son, Jack. If regular admission for a ticket was $60, what did Jun pay for the two tickets?

Answers

The amount that Jun paid for the two tickets given the discount rate and the coupon rates is $105.45.

How much was paid for the two tickets?

Discounts and coupons reduce the price of an item.

Cost of the child's ticket after the discount = (100 - 15%) x 60 = $51

Cost of both tickets after the coupon = (100 - 5) x (51 + 60) = $105.45

Answers

Answer:

8 = 2x + 4collect like terms8 - 4 = 2x4 = 2xdivide both sides by 24/2 = 2x/2X = 2

Answer:

x=2 (answer should have a positive sign.)

Step-by-step explanation:

To solve this problem, you have to isolate the x from one side of the equation.

First, switch sides.

8=2x+4

2x+4=8

Subtract by 4 from both sides.

2x+4-4=8-4

Solve.

8-4=4

2x=4

Then, divide by 2 from both sides.

2x/2=4/2

Solve.

4/2=2

x=2

The solution is 2.

Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles  )

∠ ABC = 87°

what is 6 x 18 using the distributive property

Answers

Answer:

108 is the answer and there is no explanation for this. Youc can directly multiply it.

Answer:

648

Step-by-step explanation:

There is no distributive property necessary. You would use distributive property in a problem like a(b + c).

a(b + c)

ab + ac

That is distributive property. 6 × 108 doesn't require distributive property.

6 × 108 or 6(108) or 108(6) = 648
