The line plot shows the ages of participants in two group activities at a science center.

What conclusion can be drawn about the data sets?


More 14- and 15-year olds are in group 2 than in group 1.

Group 1 participants have a greater range in age than group 2 participants.

The median age of participants in group 2 is older than the median age of participants for group 1.

The mean age of participants in group 2 is younger than the mean age of participants in group 1.


Two line plots one above the other, both are labeled from ten to twenty five by ones. The top line plot is labeled Age of participants dash group one and it has five Xs above fifteen, four Xs above fourteen, two Xs above thirteen, sixteen, and nineteen and one X above ten, twelve, seventeen, eighteen, and twenty. The bottom line plot is labeled Age of participants dash group two and it has four Xs above seventeen, three Xs above eighteen, two Xs above eleven, fifteen and sixteen and one X above twelve, thirteen, fourteen, ninteen, twenty, twenty three, and twenty five.

Ed is building a model of a house with a flat roof, as shown in the diagram. There is a chimney through the roof. Ed will cover the roof with square tiles.

If the area of each tile is 1 square inch, how many tiles will he need?

Answers

Answer:

Step-by-step explanation:

3x4

You will need to find the area first so 50in x 40in =2,000in

Then find the area the chimney takes up. 4in x 3in = 12in

2,000in - 12in =1,988 tiles for the roof.

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 1000 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run

Answers

Answer:

i think its 200 m

Step-by-step explanation:

because 20 times 1000 rotations is 20000 cm so when u convert it to meter it is 200 meter if it is km it is 0.2 km

Distance ran by Avi's pet hamster chubby is 6280 cm.

The diameter of hamster wheel = 20 cm
Now the circumference of hamster wheel is given by :-

where d ⇒ the diameter of the hamster wheel.

During one race, the number of rotations of the wheel = 100
Therefore, the distance run by chubby is given by :-
Distance ran by chubby is equal to the number of rotations of the wheel times Circumference of the wheel.
framing in equation form we get;

D⇒ Distance ran by Chubby.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 30 inches, and the length of the base is 10 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.

Answers

Perimeter = 78.7 inches
Step-by-step explanation:
From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;
= +
= +
=841 + 81
= 922
hyp =
= 30.3645
The perimeter of the triangle can be determined as;
perimeter = + +
= 30.3645 + 18 + 30.3645
= 78.729
The perimeter of the triangle = 78.7 inches

The perimeter of the triangle is 70.82 inches.

Given as :

The length of the altitude is 30 inches, and

The length of the base is 10 inches

What is right triangle?

Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.

Let, perpendicular = 30 and base = 5

According to Pythagoras theorem,

A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

perpendicular² + base² = hypotenuse²

Substitute the values,

30² + 5² =  hypotenuse²

900 + 25 =  hypotenuse² or

hypotenuse² = 925

hypotenuse = √925

hypotenuse = 30.41

The perimeter of the triangle can be determined as:

Perimeter of the triangle = l₁ + l₂ + l₃

Perimeter of the triangle = 30.41+ 10 + 30.41

Perimeter of the triangle = 70.82

Hence, the perimeter of the triangle is 70.82 inches.

Because the radius is 4.5 inches we use the area formula for a circle ( pi * radius squared) to find the answer so

4.5 * 4.5 * 3.14 which will equal 63.585 inches squared

Hope this helps

Answer:

D. 4.5

The Area is 63.585

Step-by-step explanation:

So the diameter is twice the size of the "r" or radius so divide 9 by 2

which is 4.5

The formula for a circle is πr^2

4.5 times itself is 20.25

times pi or 3.14 is 63.585

Hello! answer: 105

Step-by-step explanation:

You can find the area separately then add it up so... 10 × 6 = 60 10 × 9 = 90 90 ÷ 2 = 45

60 + 45 = 105 therefore the area is 105

Answer:

105 square meters

Step-by-step explanation:

Area= a + b/2 • h

Area= 15 + 6/2 • 10

Area= 21/2 • 10

Area= 10.5 • 10

Area= 105
