Answer with Step-by-step explanation:

The radius of the bull’s-eye of the dartboard is 8 inches.

The radius of each concentric circle is 8 inches more than the radius of the circle inside it.

Radius of first circle=8 in.

Radius of second circle=16 in.

Radius of third circle=24 in.

Radius of fourth circle=32 in.

Area of C=Area of the third circle-Area of second circle

                     = π×24×24-π×16×16

                   = 320π sq. in.

Total area of dartboard=Area of fourth circle=π×32×32

                                                            =1024π sq. in.

P( the dart will hit in area C)= area of c/total area of dart board

                                             =320π/1024π

                                           =  5/16

Hence, correct option is:

B.5/16

For males in a certain town, the systolic blood pressure is normally distributed with a mean of 125 and a standard deviation of
Gala2k [10]

Answer:

G= 93 to 147

Step-by-step explanation:

From the question we are told that

Mean x = 120

Standard deviation o = 9

Percentage for men =99.75%

Generally the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean  

Standard deviation n= 9

Mean x= 120

Generally the interval  of systolic blood pressure for middle 99.7 of male G is mathematically given as

G = mean + 3 * o

G = 120 + 3 * 9

G = 93 to 147

Can you pls help me with this question thank you

How can expressions be written and evaluated to solve for unknowns in the real world?

Writing expressions requires figuring out which quantity in a situation is unknown, and define a variable to represent that quantitiy.

We look for words in the problem that will help us out what kind of operation to use in a given situation.

Example:

Donna bought 5 chocolate bars, and then ate some. Write an expression to represent how many chocolate bars Donna has left.

If we let the variable c represent the number of chocolates Donna has eaten, then we can write the expression on how many bars Donna has left as: 5 - c

How do I graph an inequality in one variable?
Masja [62]
It depends on the variable.

If it's something like x < 2, your graph would be a vertical line at x = 2, and everything to left of that line shaded in (because of the less than).

Similarly for y, except it would be a horizontal line with either everything above or below shaded.

You can have other equations like 0<x<4 where everything between x = 0 and x = 4 would be shaded

Use the distributive property to remove the parentheses. -6(5y-2u-3)
olga55 [171]
<h2>Answer: -30y + 12u + 18 </h2>

<h3>Step-by-step explanation:</h3>

    <em> by multiplying each term in the parentheses by the term outside</em>

-6(5y-2u-3) = (-6 × 5y) + (-6 × - 2u) + (-6 × -3)

                   = -30y + 12u + 18
