Answer:

X = 62

Step-by-step explanation:

The inside of a triangle is always equal to 180º therefore, you need to add everything up to equal 180. It should look like

(x + 1) + 55 + x = 180

Now you just solve.

Since there are 2 x's you can combine the like terms making them equal 2x

Now the equation should look like 2x + 1 + 55 = 180

Simplify the other like terms: 2x + 56 = 180

Now you want to get x by itself so you subtract 56 from both sides:

2x + 56 = 180

-56 -56

------------------------

2x = 124

Now to finish getting x by itself, divide both sides by 2.

2x = 124

----- ------

2 2

x = 62

FINALLY you plug in x to see if it worked.

(62 + 1) + 55 + 62 = 180

The owner of a football team claims that the average attendance at games is over 523, and he is therefore justified in moving th

USPshnik [31]

Answer:

C) There is not sufficient evidence to support the claim that the mean attendance is greater than 523.

Step-by-step explanation:

Let μ be the the average attendance at games of the football team

The claim: the average attendance at games is over 523

Null and alternative hypotheses are:

$H_{0}$ : μ=523

$H_{a}$ : μ>523

The conclusion is failure to reject the null hypothesis.

This means that test statistic is lower than critical value. Therefore it is not significant, there is no significant evidence to accept the alternative hypothesis.

That is no significant evidence that the average attendance at games of the football team is greater than 523.

Solve for Inequality

uysha [10]

Answer:

x > -1

Step-by-step explanation:

Divide the whole inequality by 9.

( $\frac{x}{3}$ +1)> $\frac{6}{9}$

Subtract 1.

$\frac{x}{3}$ > $\frac{2}{3}$ - 1

$\frac{x}{3}$ > - $\frac{1}{3}$

Multiply by 3.

x > -1

The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes: Graph titl

Degger [83]

Answer:

The initial value is 3

It represents the distance between the bird and its nest before any elapsed time which is 3 miles.

Step-by-step explanation:

The graph is shown in the attached image.

The general form of a straight line is:

y = mx + c

where:

m is the slope and c is the y-intercept.

The y-intercept is also known as the initial value. It is the value of y at x=0.

From the givens, we can note that at x = 0, the y-value is 3. This means that the y-intercept is 3.

Now, in the problem, x represents the time in minutes while y represents the distance of the bird from the nest in miles.

At x = 0, meaning before any time elapsed, the distance of the bird from its nest was 3 miles.

Hope this helps :)
