Answer:
$19.20
Step-by-step explanation:
if every hour they pay$4.80 and they go ice skating for 4 hours all you have to do is multiply $4.80 x 4
Answer:
x=10
Step-by-step explanation:
5/8x - 11/2 = 3/4
Multiply each side by 8 to clear the fractions
8(5/8x - 11/2 = 3/4)
5x - 44 = 6
Add 44 to each side
5x-44+4= 6+4
5x= 50
Divide by 5
5x/5 = 50/5
x =10
Answer:
The condition for r is the following:

And for this case if we analyze the options the only impossible value is given by:
1.0528
Because this value is higher than 1 and not satisfy the general limits for r
Step-by-step explanation:
The correlation coefficient is a measure of dispersion and is a value between -1 and 1, and is defined as:
The condition for r is the following:

And for this case if we analyze the options the only impossible value is given by:
1.0528
Because this value is higher than 1 and not satisfy the general limits for r
Answer: Option D.
Step-by-step explanation:
You can calculate the surface area of this right prism by adding the area of its faces.
You can observe that the faces of the right prism are: Three different rectangles and two equal triangles.
The formula for calculate the area of a rectangle is:

Where "l" is the lenght and "w" is the width.
The formula for calculate the area of a triangle is:

Where "b" is the base and "h" is the height.
You can observe that the hypotenuse of the each triangle is the width of one of the larger rectangle, then , you can find its value with the Pythagorean Theorem:

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
Then, this is:

Therefore, you can add the areas of the faces to find the surface area of the right prism (Since the triangles are equal, you can multiply the area of one of them by 2). This is:

2.00+1.50= 3.50.
3.50x8= 28.00
I'm assuming they each paid 41.00 dollars for two games,
41.00x8= 328.00
328.00+28.00= $356.00
Hope this is correct and/or it helps!
Sorry, didn't realize my mistake.
