Answer:
A —6
Step-by-step explanation:
of people of the same sex and similar ages follow a Normal distribution reasonably closely. Weights, on the other hand, are not Normally distributed. The weights of women aged 20–29 in the United States have mean 161.9 pounds and median 149.4 pounds. The first and third quartiles are 126.3 pounds and 181.2 pounds, respectively. What can you say about the shape of the weight distribution? Why?
Answer:
Right-skewed
Step-by-step explanation:
The shape of the weight distributed is skewed, because the mean and the median are not equal.
Moreover, the distribution is right-skewed because the mean is greater than the median and because the mean is influenced by the tail of large values.
Rearrange the formula for y2
Answer:
y2 = m(x1 - x2)+ y1
Step-by-step explanation:
m = y2 - y1 / x1 - x2
m(x1 -x2) = y2 -y1
y2 = m(x1 - x2)+ y1
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
Multiply both sides by (x2 - x1)
m(x2 - x1) = y2 - y1
Add y1 to both sides
m(x2 - x1) + y1 = y2
y = m(x2 - x1) + y1

used to have a square garage with ft of floor space. recently built an addition to it. The garage is still a square, but now it has 50% more floor space. What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the percent increase in the length of one side?
Answer:
Length of the original square garage = 16.7ft
Length of the new square garage= 20.5ft
Percentage increase in the length of the side = 23%
Step-by-step explanation:
Yossi used to have a square garage with 280 ft? of floor space. He recently built an
addition to it. The garage is still a square, but now it has 50% more floor space. What was the length
of one side of the garage originally? What is the length of one side of the garage now? What was the
percent increase in the length of one side?
Area of the original square garage = 280ft²
Area of a square = length²
280ft² = length²
Find the square root of both sides
√280ft² = √length²
16.7ft = length
Length of the original square garage = 16.7ft
Area of the new square garage = 280ft² + 50% of 280ft²
= 280ft² + 0.5 × 280ft²
= 280ft² + 140ft²
= 420ft²
Area of a square = length²
420ft² = length²
Find the square root of both sides
√420ft² = √length²
20.5ft = length
Length of the new square garage= 20.5ft
Percentage increase in the length of the side = (new - old) / old × 100
= (20.5 - 16.7) / 16.7 × 100
= 3.8 / 16.7 × 100
= 0.23 × 100
= 23%
Percentage increase in the length of the side = 23%

The perimeter of a rectangular lot is 86 feet. The
length is 19 feet greater than the width. Find the
length and width.
Answer: width would be 7 feet and the length would be 26
Step-by-step explanation:
width : w
length: 19 +w
2l + 2w = 66
2(19+w) + 2w= 66 distribute
38 + 2w + 2w = 66 add the w values
38 + 4w =66 subtract 38 from both sides
4w = 28 divide by 4
w= 7
19+7= 26

One serving a Velveeta contain 13% of the daily recommended amount of calcium If it is recommended that you get 1,000 mg of calcium daily how many milligrams are in one serving of Velveeta
Answer:
130 mg
Step-by-step explanation:
As the statement indicates that the daily recommended amount of calcium is 1,000 mg and that Velveeta contains 13% of that, you have to calculate the 13% of 1,000 to find the answer:
1,000*13%=130
According to this, there are 130 mg of calcium in one serving of Velveeta.

Is the square root of 58 a rational number
Answer:
The square root of 58 is a rational number if 58 is a perfect square.
Step-by-step explanation:
It is an irrational number if it is not a perfect square. Since 58 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 58?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.
is this what you needed or
The square root of the number is A = √58 is not a rational number
Given data ,
Let the first number be represented as p
where the value of p = 58
Now , the square root of the number is expressed as
A = √58
The radical form of a number refers to expressing a number using a radical symbol (√) to represent a root.
It is used to express the roots present in the number.
So , A = √58
On simplifying , we get
A = 7.6157731058639082856614110271583...
On further simplification , we get
A = the square root of 58 is not a rational number
Hence , the square root of 58 is an irrational number because it cannot be expressed as a fraction of two integers

Hence, in the number system, we can write it down as 1, 2, 4, 8....to 10th divison. The linear equation will be 2(2)^n-1.
Where n is equal to number of divisions, and the value 2 is the virus bening multiplied by 2.

5(x+8)+3
3.6x-7-5.1x
4+8x+2.2-10x
Answer:
1. 5x +43
2. -1.5x - 7
3. 6.2 - 2x
Step-by-step explanation:
Equation 1:
5 (x+8) +3
First, we can distribute the 5 to the (x+8) and get 5x + 40. Distributing is when we multiply the 5 by the first number (x) and then by the second number (8) Because they aren't like terms (don't both have x's) we cannot combine then and must keep them separated by a subtraction sign
Now we have: 5x + 40 + 3
Next, we can combine the like terms. This means that any that have the same variable can be combined. So, the 5x has no other x's so he has to stay how he is. The 40 and the 3, however, can be added together to get 43.
Our finished equation is: 5x + 43
Equation 2:
3.6x - 7 - 5.1x
First, we can combine like terms as we learned in the last problem. This would be our x's since we have multiple.
We can add 3.6x and -5.1x and get -1.5x
Now we have: -1.5x - 7
Equation 3:
4 + 8x + 2.2 - 10x
We can start with either the numbers with x's or without but I'll just do the x's. So we have 8x and -10x. Adding these together would get us -2x.
Next, we can combine 4 and 2.2 and get 6.2.
Now, putting these back into our equation would look like this:
6.2 - 2x
