Answer:

M = - 3

Step-by-step explanation:

Find the Slope:

Slope is equal to the change in  y  over the change in  x

, or rise over run.

m  =  [tex]\frac{change in Y}{change in X}[/tex]

The change in  x  is equal to the difference in x-coordinates (also called run), and the change in  y  is equal to the difference in y-coordinates (also called rise).

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Substitute in the values of  x  and  y  into the equation to find the slope.

m = [tex]\frac{3-(9)}{4-(2)}[/tex]

Simplify.

m = [tex]\frac{-6}{2}[/tex]

m = -3

Answer:

(f+g)(x) = [tex]3x^{2} - 6[/tex]

Step-by-step explanation:

First, lets understand what (f+g)(x) means.

(f+g)(x) is when you are taking the values in the function f(x) and adding it to the values in the function g(x).

So, this is what the equation looks like when you substitute the functions in to (f+g)(x):

(f+g)(x) = [tex](2x^{2} +1) + (x^{2} -7)[/tex]

Now, combine like terms and Simplify:

(f+g)(x) = [tex]3x^{2} - 6[/tex]

This is your final answer.

Answer:

10.5 seconds.

Step-by-step explanation:

Remember that this is an estimate. It is meant for you to do in your head. It is not meant for Google or a calculator.

100 meters is 1/2 of 200 meters.

100 meters time is roughly 1/2 that for 200 meters.

21 seconds * 1/2 = 10.5 seconds.

Answer:

  96.58

Step-by-step explanation:

The formula for simple interest is ...

  I = Prt

where P is the principal, r is the rate, and t is the time period in years.

Exact interest is computed using 365 days per year, so the time period is ...

  t = 150/365

Then the interest is ...

  I = 2350(0.10)(150/365) = 96.58

Answer:

Maya had 22 cookies she gave out 7 to her classmates, how many does she have now?

The value of equation 22 − n = 15 is 7.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Equation:  22 − n = 15

Now, Subtract 22 from both side

22 - n - 22 = 15 - 22

-n = -7

Now, multiply both side by (-1)

n= 7

Hence, the value of n is 7.

Answer:

[tex] (f - g)x = -4x - 25 [/tex]

Step-by-step explanation:

Given:

[tex] f(x) = -7x - 12 [/tex]

[tex] g(x) = 13 - 3x [/tex]

Required:

[tex] (f - g)x [/tex]

Answer:

[tex]w=2(P+2b)[/tex]

Step-by-step explanation:

[tex]4P=2w-8b[/tex]

Switch sides:

[tex]2w-8b=4P[/tex]

Add 8b to both sides:

[tex]\2w-8b+8b=4P+8b[/tex]

[tex]2w=4P+8b[/tex]

Divide both sides by 2:

[tex]\frac{2w}{2}=\frac{4P+8b}{2}[/tex]

[tex]w=2P+4b[/tex]

Factor out the common factor (2):

Step-by-step explanation:

Definite Integrals

One of the properties of the definite integrals called This is called internal addition is:

[tex]\int _a^b f(x)dx=\int _a^c f(x)dx+\int _c^b f(x)dx[/tex]

We are required to find

And we are given:

[tex]\int _{-3}^0 R(n)dn =12[/tex]

[tex]\int _{0}^4 R(n)dn =-5[/tex]

Thus, applying the internal addition property:

[tex]\int _{-3}^4 R(n)dn =12-5=7[/tex]

Step-by-step explanation:

Step-by-step explanation:

Given that the logical statement is

"If a divides bc, then a divides b or a divides c"

we can see that a must divide one either b or c from the statement above

A) If a does not divide b or a does not divide c, then a does not divide bc.

This is False because a can divide b or c

 B) If a does not divide b and a does not divide c, then a does not divide bc.

this is True for a to divide bc it must divide b or c (either b or c)

C) If a divides bc and a does not divide c, then a divides b.

This is True since a can divide bc and it cannot divide c, it must definitely divide b

D) If a divides bc or a does not divide b, then a divides c.

This is True since a can divide bc and it cannot divide b, it must definitely divide c

E) a divides bc, a does not divide b, and a does not divide c.

This is False for a to divide bc it must divide one of  b or c

Answer:

Throughout the segment below, the definition including its particular question is mentioned.

Step-by-step explanation:

The probability of developing cancer

= 0.07  

The probability of someone not getting cancer

= 1 - 0.07

= 0.93  

Provided that if women have cancer, the risk of someone not testing positive is:

= 0.10  

Therefore, if a female requires cancer, the risk of testing positive

= 1 - 0.10

= 0.90  

The Probability of positive test

= 0.055 (whenever a woman does not have cancer)  

Therefore, whenever a woman does not have cancer, the risk of not testing positive will be:

= 1 - 0.05

= 0.955

Now,

By using the law of conditional probability, we get

⇒  [tex]P(\frac{B}{A} ) = \frac{P(A \ and \ B)}{P(A)}[/tex]

⇒  [tex]P (A \ and \ B) = P(A)\times P(B)[/tex]

⇒ P (having cancer as well as positive tests) = P(having cancer) × P(Effective results, because she has cancer)

⇒  [tex]0.07\times 0.90[/tex]

⇒  [tex]0.063[/tex]

Correspondingly,

P (not getting cancer and testing effective or positive)

= [tex]0.93\times 0.05[/tex]

= [tex]0.04655[/tex]

P (with a good test result)

= [tex]0.063 + 0.0465[/tex]

= [tex]0.1095[/tex]
