To gather data for a statistics project, a student asked 10 friends how many hours of sleep they got on the previous night. The data are shown in the following list.

Answers

Answer 1

Answer:

3

Step-by-step explanation:

INTERQUARTILE RANGE (IQR) = Q3 - Q1

Rearranging the data: 3, 4, 5, 5, 6, 7, 7, 8, 9, 9

Q3 = 0.75(n+1)th term

Q3 = 0.75(10 + 1) th term

Q3 = 0.75(11)th term = 8.25th term

Taking the 8th term = 8

Q1 = 0.25(11)th term = 2.75th

Taking the average of the 8th and 9th term:

(5 + 5) / 2 = 10/2 = 5

Q3 - Q1 = (8 - 5) = 3

A hot air balloon traveled 2.5 hours at a speed of 450 km/hr. What distance did it travel?

Answers

Answer:

1,125 km

Step-by-step explanation:

So you want to find out how far the balloon went and we already know how fast and how long it's been traveling for. So now, all you have to do is come up with an equation which looks like:

2.5 x 450

Which equals 1,125 km.

The speed 450km/hour tells us that the balloon travels 450km in one hour. To find how much it traveled in 2.5 hours, we multiply 450 by 2.5.

450 x 2.5 = 1125 km

Therefore, the balloon traveled 1125 km in 2.5 hours

△DEF and △FGH similar right triangles. The coordinates of all the vertices are integers. The relationship between the slope of DF¯¯¯¯¯ and the slope of FH¯¯¯¯¯¯ cannot be determined, because the triangles are congruent. The slope of DF¯¯¯¯¯ is less than the slope of FH¯¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for DF¯¯¯¯¯ than for FH¯¯¯¯¯¯ . The slope of DF¯¯¯¯¯ is equal to the slope of FH¯¯¯¯¯¯ . This this because ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for DF¯¯¯¯¯ as for FH¯¯¯¯¯¯ The slope of DF¯¯¯¯¯ is greater than the slope of FH¯¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for DF¯¯¯¯¯ than for FH¯¯¯¯¯¯ .

Answers

Answer:

Congruent triangles are triangles with the same sides and the same measure of angles. You are given triangle DEF which is similar to triangle FGH. From the figure, side FH is larger than side DF. So the statement of them being congruent cancels out. Triangle DEF is smaller in size than triangle FGH. So they are not congruent. The slope is defined as the rise overrun. Side DF has the same slope as side FH. Sides DE and FE are proportional to sides FG and HG. Only C and D are correct.

Suppose BD bisects ABC. If m ABD = 12x+24 and m DBC = 20x +16 what is m ABC?

Answers

Answer:

The measure of ABC is 72

Step-by-step explanation:

if the angle ABC is bisected, it means that the two angles ABD and DBC are equal;

Thus;

12x + 24 = 20x + 16

20x -12x = 24-16

8x = 8

x = 1

The measure of angle ABC is the sum of the two angles

ABC = 12x + 24 + 20x + 16

ABC = 32x + 40

Substitute x = 1

ABC = 32(1) + 40

ABC = 72 degrees

How would you graph x > 0 on a number line?
А
Draw an open circle over 0, and shade the arrow to the right.
B
Draw a closed circle over 0, and shade the arrow to the right.
С
Draw an open circle over 0, and shade the arrow to the left.
D
Draw a closed circle over 0, and an open circle over 10.

Answers

Answer:

A

Step-by-step explanation:

The correct way to graph x > 0 on a number line is option B) Draw a closed circle over 0 and shade the arrow to the right.

In this case, the inequality x > 0 represents all values of x that are greater than zero. By placing a closed circle on zero, we include the value of zero in the solution set. The shading of the arrow to the right indicates that all values greater than zero are included in the solution.

Since the inequality is strict (x > 0), we use a closed circle to represent zero, indicating that zero is part of the solution set. An open circle would be used if the inequality was non-strict (x ≥ 0), excluding zero from the solution set. However, in this case, zero is included, so a closed circle is used.

A local pizza shop has a membership program for frequent buyers. The membership costs $25 per month and members get a discounted price of $1.50 per slice of pizza. Aaliyah purchased a membership to this pizza shop. How much would Aaliyah have to pay the pizza shop if she bought 6 slices of pizza this month? What would be the monthly cost for x slices of pizza?

Answers

Answer:
$34
$26.5
Step-by-step explanation:
Membership cost per month = $25
Price of a slice of pizza for members= $1.50
How much would Aaliyah have
to pay the pizza shop if she bought 6 slices of pizza this month
Total cost of Aaliyah on 6 slices of pizza = membership cost per month + prices of 6 discounted pizza
= $25 + $1.50(6)
= $25 + $9
= $34
What would be the
monthly cost for a slices of pizza
Monthly cost of Aaliyah a slices of pizza = membership cost per month + price of 1 discounted pizza
= $25 + $1.5
= $26.5

Answer:

$1.50x6=$9+$25=$34

Which equation is equivalent to 2x + 3y = 12?
y=2/3x+4
y= -2/3x+12
y= -2/3x+4
y=2/3x+12

Answers

Answer:

y= -2/3x + 4

Step-by-step explanation:

2x + 3y = 12

3y = 12 - 2x

3y/3 = 12/3 - 2x/3

y = 4 -2x/3

Answer:

([tex]x[/tex], [tex]y[/tex]) = (30, 16)

Step-by-step explanation:

First find the similarity

Since you know the legnth of the hypotenuse (the longest one) for both traingles, you can find the similarity by dividing the longer by the shorter:

50 ÷ 20 = 2.5

The similarity between the 2 triangles is 2.5.

Now find the length of [tex]x[/tex] on the longer one, use the shorter one's length and the similarity:

12 × 2.5 = 30

So the length of [tex]x[/tex] is equal to 30

Now lets find [tex]y[/tex], lets use the length of the larger triangle this time and divide the length of the longer leg (there are 2 legs in every triangle, if you don't know the hypotenus's length, use the pythagorean theorem) and divide it by the similarity:

40 ÷ 2.5 = 16

[tex]y[/tex] = 16

WooHoo! ([tex]x[/tex], [tex]y[/tex]) = (30, 16)
