Answer:

3. It is likely.

Step-by-step explanation:

Let's assume the dartboards circles have radius of r, 2r, 3r and 4r from inner side

<u>Then the areas covered will be as:</u>

  • point 20 = πr² = S
  • point 15 = π(2r)² - πr² = 3πr² = 3S
  • point 1 0 = π(3r)² - π(2r)² = 5πr² = 5S
  • point 5 = π(4r)² - π(3r)² = 7πr² = 7S

Total area of the dartboard is S+3S+5S+7S = 16S

The area of point 5 is 7S. And the area of non- 5 point is 16S - 7S = 9S

The probability of scoring at least 10 points is:

  • 9S/16S = 0.5625

As it is between 1/2 and 1, the probability is in 'likely' region

<u>So the correct answer choice is:</u> 3. It is likely

The admission to a local fair is $10 for each adult and $6 for each child. Each ride costs $1.50 for an adult and $1 for a child
S_A_V [24]
So first start out by writing an expression for the cost of the child and the adult separately.

Child:
6 + 1r   ($6 + $1 per ride)

Adult:
10 + 1.5r   ($10 + $1.50 per ride)

to find how much more the adult will spend, just do Adult Expression - Child Expression which will be:

10 + 1.5r - (6 + 1r)  just simplify this

For Part B, use your equation from part A where r = 7

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Yakvenalex [24]

Answer: (C) even

<u>Step-by-step explanation:</u>

A function is even when f(x) = f(-x)

A function is odd when f(-x) = -f(x)


f(x) = -2x⁴ + 3x²

f(-x) = -2(-x)⁴ + 3(-x)²

      = -2x⁴ + 3x²

f(x) = f(-x) so the function is even


-f(x) = -(-2x⁴ + 3x²)

       = 2x⁴ - 3x²

f(-x) ≠ -f(x) so the function is not odd.

A wall has been built with two pieces of sheetrock, a smaller one and a larger one. The length of the smaller one is stored in t
marishachu [46]

Answer:

The answer is: small+large.

Step-by-step explanation:

If the variable of the smaller sheetrock is stored in small:

var small.

And the variable of the larger sheetrock is stored in large:

var large.

The length of the wall will be the sum of the two pieces of sheetrock:

  • small+large

For example:

var small = 5;

var large = 10;

small+large = 5 + 10 = 15 is the length of the wall.
