If the total area of a dartboard is 30,000 mm2 and the area of the bull's-eye is 1000 mm2, what is the probability of getting a bull's-eye?A. 6%
B. 3%
C. 33%
D. 25%

Answers

Answer 1
Answer:

Answer:

The correct option is B.

Step-by-step explanation:

It is given that the total area of a dartboard is 30,000 mm² and the area of the bull's-eye is 1000 mm².

The probability of getting a bull's-eye is

\text{Probability of getting a bull's-eye}=\frac{\text{Area of the bull's-eye}}{\text{Total area}}

\text{Probability of getting a bull's-eye}=(1000)/(30000)

\text{Probability of getting a bull's-eye}=(1)/(30)

\text{Probability of getting a bull's-eye}=0.0333\approx 3\%

Therefore the correct option is B.
Answer 2
Answer: chances of hitting bull's-eye is (1000)/(30,000) that =(1)/(30) 1-:30= 0.03= 3%

What is the square root for √84?
Simplified and the non simplifed one

Answers

To simplify the square root, find the prime factorization of the number within the square root:

84 = 7 * 12

7 * 12 = 7 * 4 * 3

7 * 4 * 3 = 7 * 2 * 2 * 3

√(84) = √(2 * 2 * 3 * 7)

Take any number that is repeated twice within the prime factorization, and move it outside of the root:

√(2 * 2) = 2

√(2 * 2 * 3 * 7) = 2 √(3 * 7) = \boxed{2 √(21)}

The simplified form of √84 will be 2√21.

The non-simplified form is found by putting the term into the calculator:

√(84) = \boxed{9.166}

Rounded to the nearest thousandths place, the non-simplified form of √84 will be 9.166.

•Simplified Square Root for √84 is 2√21
√4*21=√84.
Now extract and take out the square root √4 * √21. Root of √4=2 which results into 2√21

•Determine the square root.
The square root of eighty-four √84 = 9.16515138991

Lines g and h are parallel and m 1 = 45°. What is m 8?

Question 7 options:

45°

65°

115°

135°
Save

Answers

Answer:

m<8=45\°

Step-by-step explanation:

we know that

If the lines g and h are parallel

then

m<8=m<1 -----> by alternate exterior angles

see the attached figure to better understand the problem

we have that

m<1=45\°

therefore

m<8=45\°
parallel means m1 = m2
so m2=45

Functions f(x) and g(x) are shown below.f(x) = x^2
g(x) = x^2 8x 16
In which direction and by how many units should f(x) be shifted to obtain g(x)?

Answers

We can factor g(x) as (x+4)^2.  Clearly, g(x) is simply f(x+4), so f(x) should increase each x by 4 to achieve the same result as g(x).  Therefore, f(x) should be shifted 4 units in the positive-x (or right) direction.

A 6 ounce bag of raisins costs $2.46.an 8 ounce bag of raisins costs $3.20.which is the better deal?

Answers

6 ounce bag

The eight ounce bag costs one cent less per ounce. It's therefore a better deal.

7 times the difference of a number and 3.2 is 8.4.

Answers

because subtraction comes before multiplication on the order of operations we have to put in parenthasis in this problem.

(x-3.2) is what we have so far.

then we multiply it by 7

so 7(x-3.2)=8.4
