Please explain what the gap between the 7 and the 4 is, because I'm sure it's not 74x?

Either way, it looks like a linear graph, in which case yes, the range is going to be y∈<span>ℝ. Therefore, it's false, as it's for ALL real values of y, including negative values.</span>

It is reported in USA Today that the average flight cost nationwide is $445.99. You have never paid close to that amount and you

nlexa [21]

Answer:

$H_0$ : $\mu \leq 445.99$

$H_a$ : $\mu > 445.99$

Step-by-step explanation:

It is given the average cost of the flight nationwide is $ 445.99

I wanted to $\text{perform the hypothesis test}$ to determine that the true average is greater than $ 445.99

Let the hypothesis that the true average is actually greater than $445.99

Therefore,

the $\text{null hypothesis}$ for the test is :

$H_0$ : $\mu \leq 445.99$

And the alternate hypothesis is :

$H_a$ : $\mu > 445.99$

Use the multiplication property of equality to multiply both sides of the equation by 1/6 to get: (1/6)6x=(1/6)48.

zzz [600]

X= 8 because by multiplying the fraction with a whole number you had to to convert it to i a fraction and that equals one and then 1/6 times 48 is 8

Pls help for 27b!!!!!!!

rodikova [14]

Step-by-step explanation:

$\beta$

is a root of the quadratic

$4 {x}^{2} - 10x + 5$

This quadratic isn't factorable so use the quadratic formula

$- b + - \sqrt{ \frac{b {}^{2} - 4ac }{2a} }$

The plus and minus sign after b means we going to have two roots.

The roots are

$\frac{5 + \sqrt{5} }{4}$

and

$\frac{5 - \sqrt{5} }{4}$

We subsitue those values for Beta.

27a.

$\frac{5}{2}$

27b.

HELP PLZ RN<3<br> which graph displays a rate of change of 2.5?

Ilya [14]

Answer:

The second graph.

Step-by-step explanation:

The first graph has a negative slope, so that can't be the right answer.

The last graph isn't steep enough to show a rate of 2.5.

This leaves us with the middle graph which is correct.
