Answer:
B) y=1/5x-3 where 1/5=0.2.
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=1/5(x-(-5))
y+4=1/5(x+5)
y=1/5x+5/5-4
y=1/5x+1-4
y=1/5x-3
5. photo album: $25.50, 10% markup
Answer:
$28.05
Step-by-step explanation:
If you want to find how much the photo album is after the markup, you first have to find 10% of the original price. 10% of $25.50 is $2.55, so you add $2.55 and $25.50 to find the price after the markup.

What is the radius and center for (x - 2)2 + y2 16? 0000 A. r = 16; center is (2,0) B. r = 4; center is (-2,0) C. r = 16; center is (-2,0) D. r = 4; center is (2,0)
Answer:
D. r = 4; center is (2, 0)Step-by-step explanation:
Equation of a circle:
(x - h)² + (y - k)² = r², where (h, k) is the center and r is the radiusGiven equation:
(x - 2)² + y² = 16Rewrite as:
(x - 2)² + (y - 0)² = 4²The center is (2, 0)
The radius is r = 4
Correct choice is D
General equation
(x-h)²+(y-k)²=r²Where centre is (h,k)
radius is r
(x-2)²+(y-0)²=4²Radius=4
centre (2,0)

Shamika bought 3 skirts that cost $25 each before the discount. What was her total after thediscount?
A. $45.00
B. $48.75
C. $52.50
D. $56.25
Answer:
The answer is C and please give me brainliet And a like!
Where the above parameters are given, Shamika's total after the discount is $56.25. (Option D)
How to compute the above resultAccording to the table, if the total purchases are less than $50, the discount is 25%.
Shamika bought 3 skirts at $25 each, so her total purchase amount is 3 * $25 = $75.
Since $75 is less than $50, she qualifies for a 25% discount.
To calculate the discount, we multiply the total purchase amount by the discount rate -
Discount = 25% of $75 = (25/100) * $75 = $18.75
To find her total after the discount, we subtract the discount from the total purchase amount -
Total after discount = Total purchase amount - Discount
Total after discount = $75 - $18.75 = $56.25
Therefore, Shamika's total after the discount is $56.25. (Option D)

What is the approximate surface area of a cylinder that's base has a radius of 2, and it's lateral rectangle has a length of 6.28, and a width of 4?
Answer:
Surface area of cylinder = 50.26 unit² (Approx.)
Step-by-step explanation:
Given:
Radius of base r = 2 units
Width of lateral rectangle = 4 units
Length of lateral rectangle = 6.28 units
Find:
Surface area of cylinder
Computation:
Surface area of cylinder = 2[Area of base] + Area of lateral rectangle
Surface area of cylinder = 2[πr²] + [l][b]
Surface area of cylinder = 2[(22/7)(2)²] + [6.28][4]
Surface area of cylinder = 2[(22/7)(4)] + 25.12
Surface area of cylinder = 25.14 + 25.12
Surface area of cylinder = 50.26
Surface area of cylinder = 50.26 unit² (Approx.)

A student evaluated -4+x for x = -9 1/2and got an answer of 5 1/2? What might th student have done wrong.
Answer:
Step-by-step explanation:
Expression evaluated by the student is,
(-4 + x)
For x = [tex]-9\frac{1}{2}[/tex]
Value of the expression will be,
(-4 + x) = [tex]-4+(-9\frac{1}{2})[/tex]
= [tex]-4-9-\frac{1}{2}[/tex]
= [tex]-13-\frac{1}{2}[/tex]
= [tex]-13\frac{1}{2}[/tex]
While student evaluated the value of the expression as [tex]-5\frac{1}{2}[/tex].
Mistake done by the student may be in the first step [tex][-4+(-9\frac{1}{2})][/tex].
He might have subtracted [tex](-9\frac{1}{2})[/tex] from (-4).

Consider two population distributions labeled A and B. Distribution A is highly skewed and nonnormal, while distribution B is slightly skewed and near normal. In order for the sampling distributions of A and B to achieve the same degree of normality: A. Population A will require a larger sample size. B. Population B will require a larger sample size. C. Populations A and B will require the same sample size. D. None of these.
Answer:
A. Population A will require a larger sample size.
Step-by-step explanation:
A highly skewed distribution shows that too much data is concentrated where it is highly skewed.
If the sample size in increased the data may not concentrate at the same point and the skewness is normal that is it is mesokurtic.
The normal curve called the mesokurtic is neither very peaked nor very flat topped.
Populations A and B cannot have the same sample size as there is difference in their skewness.
Therefore option C and D are incorrect.
Option B is also incorrect because if B will require a larger sample size then the skewness may almost finish and the data may have the same concentration at all points.It will become flat topped i.e platy kurtic.
So only option A is correct.
In creasing the sample size will make the curve normal and mesokurtic.

What is the area of this triangle?
Answer:
The area of this triangle is.. [tex]30 in^2[/tex]
Step-by-step explanation:
6 x 10 divided by 2 = 30
Answer:
30 cm²
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 )
Here b = 6 and h = 10 , then
A = [tex]\frac{1}{2}[/tex] × 6 × 10 = 3 × 10 = 30 cm²
My little brother spent $5 on comic books and magazines. He bought 4 items. If comic books
cost $1 and magazines cost $2, how many of each item did my brother buy?
comic books
magazines
No links please!
Thank you
Answer: He bought 1 magazine and 3 comic books.
Step-by-step explanation: If comic books cost $1 and magazines cost $3, the equation for the problem should look like this: 2(m) + 1(c) = 5, since you know that the brother spent $5 in total. "m" represents the number of magazines purchased while "c" represents the number of comic books purchased. If you plug in 1 for "m" and 3 for "c", the equation would be true and would equal a total of $5. Also, 1 magazine and 3 comic books would mean that the little brother did, in fact, purchase 4 items.
Peter has a coupon for 15% off the price of any item in a sporting good store he wants to buy a pair of sneakers that are priced at $36.99 about how much will it take sneakers cost after the discount
Answer:
$31.44
Step-by-step explanation:
According to the word problem, Peter has a coupon for 15% OFF.
This means the price will reduce by 15%.
To solve this, first, change the percentage (15%) to decimal form.
To do this, divide the percentage by 100.
15 / 100 = 0.15.
0.15 is the decimal form of 15%.
Next, multiply the decimal form of the percentage by the price.
36.99 x 0.15 = 5.5485
Lastly, subtract the product from the original price.
36.99 - 5.5485 = 31.4415
In this case, the product goes above the hundredths place.
So we must round 31.4415 to the hundredths place.
31.4415 ≈ 31.44
Therefore, the sneakers are $31.44 after the discount of 15%.
