How do I find the solution to this?

Answers

Adding all of these should equal to 180 from the way the angle is set up.

So the equation should be:

(3x + 2) + (2x + 5) + (2x - 9) = 180

You can remove parentheses as it doesn’t affect the equation since it is all addition.

Let’s first add the common variables together.

3x + 2x + 2x = 7x
2 + 5 + (-9) = -2

So now we should have:

7x - 2 = 180

Now add 2 to both sides.

7x = 182

Divide both sides by 7 to isolate x.

x = 26

So x is 26.

Answer:

3x+2+2x+5+2x-9=180(being linear pair)

7x-2=180

7x=180+2

x=182/7

x=26

The mean number of rushing yards for one NFL team was less than 105 yards per game. If a hypothesis test is performed, how should you interpret a decision that rejects the null hypothesis

Answers

Answer:

Null hypothesis rejected means that there is significant evidence to conclude that the team's mean rushing yards per game is less than 105 yards.

Step-by-step explanation:

The mean number of rushing yards for one NFL team was less than 105 yards per game.

At the null hypothesis, we test if the mean number of rushing yards for the team was the league's mean, which is close to 105 yards per game, that is:

[tex]H_0: \mu = 105[/tex].

At the alternate hypothesis, we test if there is significant evident to conclude that this team average is less than 105 yards per game, that is:

[tex]H_1: \mu < 105[/tex]

How should you interpret a decision that rejects the null hypothesis?

Null hypothesis rejected means that there is significant evidence to conclude that the team's mean rushing yards per game is less than 105 yards.

Answers

Step 1: Take the common logarithm of both sides of the equation. Use the power property to bring the exponent, (2x+1), down as a factor.

Step 2: Solve the equation from step 1 for x. Round your final answer to the nearest hundreth.

(2x+1)*log(5) = log(8)

4. Function h describes the height of a ball, in inches, after n bounces and is defined by
the equation h(n) = 120 * (4/5)^n

Could h(n) be 150? Explain how you

Answers

Answer:

NO

Step-by-step explanation:

(4/5)^n will always be ≤ 1  for any positve n

The equation h ( n ) = 150 is false

No , the height of the ball cannot be 150 inches

What is an Equation?

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.

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 data ,

Let the equation be represented as A

Now , the value of A is

h ( n ) = 120 x ( 4/5 )ⁿ

Now , substitute the value of h ( n ) = 150 , we get

150 = 120 ( 4/5 )ⁿ

Divide by 120 on both sides of the equation , we get

150 / 120 = ( 4/5 )ⁿ

On simplifying the equation , we get

5/4 = ( 4/5 )ⁿ

The equation is not true because we have a exponential decay function here. This height of the ball decreases with each bounce.

At bounce 0 the height of the ball is 120 inches, and then continuously decreases with a common factor of 4/5

Therefore , the value of h ( n ) can never be 150

Hence , the equation h ( n ) = 150 is false

x = 4

Step-by-step explanation:

Given that sin(13x) = cos(9x+2)

Since sintheta  = cos(90 - theta)

hence sin (13x) = cos (90 -13x)

Substitute into the original equation

cos (90 -13x) = cos(9x+2)

90-13x = 9x+2

-13x - 9x = 2 - 90

-22x = -88
