Step-by-step explanation: there are 10 people total who have a brother and 7 of those people have a sister so 7/10=.7

Answer:

First, organize them from least to greatest

15 < 16 < 17 < 22 < 24 < 25 < 28 < 32 < 38 < 40

The median is 24.5. The LQ is 15, 16, 17, 22, and 24. The UQ is 25, 28, 32, 38, and 40.

Step-by-step explanation:

The median for the data set is 24.5.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

To find the median of a set of data, we need to arrange the values in order from lowest to highest and then find the middle value.

15, 16, 17, 22, 24, 25, 28, 32, 38, 40

There are 10 values in this set, which means the median will be the average of the two middle values.

In this case, the middle values are 24 and 25.

The median of this set of data is:

(24 + 25) / 2 = 24.5

Thus,

The median is 24.5.

Answer:

Line B

Step-by-step explanation:

2x-6<2

+6 +6

2x<8

/ /

2 2

x<4

It's Number Line B. All symbols are supposed to be less than or equal to, just don't have that symbol on my keyboard.

Answer:

B

Step-by-step explanation:

2x-6 is [tex]\leq[/tex] 2 is what you start with and first, you would have to move the 6 to the other side to isolate the 2x. To do that, you do the opposite operation of the 6 which is addition. Add 6 to both sides to the eqaution would end up being 2x[tex]\leq[/tex]8. Now to isolate the x, we also have to do the opposite operation so divide the 2x and the 8 by 2. The eqaution would look like this x [tex]\leq[/tex]4. Number line B would show this ineqaulity as the arrow is going left to show that x is less than 4 but the dot is also shaded in which means that 4 can also be the answer as well. Hope this helps:)

Surface Area = 2×(5×3 + 5×2 + 3×2) = 62 inches squared.

Step-by-step explanation:

Answer:

50=2(10+w)

Step-by-step explanation:

We know that perimeter is equal to the sides of a shape

A rectangle has two of the same length and two of the same width

P=2l+2w

We know the perimeter and length so plug that in and solve for w

50=2(10)+2w

50=2(10+w) - That matches answer choice D

30=2w

w=15

Answer:

Equation: 2 (w + 10) = 50

Step-by-step explanation:

Equation of the perimeter of a rectangle:

=> 2 ( w + l) = P where w= width, l = length, and P = perimeter

Substitute the given values:

=> 2 ( w + 10) = 50

There you have it!

Answer:

-2/5

Step-by-step explanation:

The full equation would be y = -2/5x + 1

1 is the y intercept, and the slope would be -2/5 because we move 2 spaces down and 5 spaces to the right to get from one point to another.

Answer:

C) $40.50

Step-by-step explanation:

It is given to you that 20 articles cost $90. Find the unit cost of the articles. Divide the total cost of the articles with the amount of articles there are:

$90/(20 articles) = $4.50/article.

Each article costs $4.50 each.

Next, find the cost of 9 articles. Multiply the total amount of articles with the unit cost:

4.50 x 9 = 40.50

C) $40.50 is your answer.

Answer:

C

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Give x is 4 more than 6, that is x = 10 , then

b = x = 10 and h = 2x = 2(10) = 20 , so

A = [tex]\frac{1}{2}[/tex] × 10 × 20 = 5 × 20 = 100 units² → C

Answer:

D, B, A

I think that these are right but I worked hard on trying to find the answer.

Answer:

A.

Step-by-step explanation:

A) 12 is divided by 4 since the twelve cookies are shared equally between four children.

B) 12 is multiplied by 4 since each band uniform has 12 buttons and there are four band uniforms.

C) 12 is substracted by 4 since four boats will not participate in the race out of a total of 12 boats.

D) 4 is added to 12 since there are already 12 monkeys but now 4 more will arrive.

Option A, x = [tex]\sqrt{80}[/tex]

Step-by-step explanation:

Pythagorean Theorem states: A² + B² = C² ( A and B are the legs, C is always the hypotenuse)

⇒ A² + B² = C²

⇒ 4² + 8² = x²

⇒ 16 + 64 = x²

⇒ 80 = x²

⇒ [tex]\sqrt{80} = \sqrt{x^{2} }[/tex]

⇒ [tex]\sqrt{80} = x[/tex]
