Boho (4x-10) (6x-46) what is the value of x

FinnZ [79.3K]3 years ago

Answer:

24x^2 - 244x + 460

Step-by-step explanation:

Hello!

This is a bit harder than problems you usually see, yet you solve it the same way: FOIL!

FOIL is my preference, so I will be using it to solve (4x - 10)(6x - 46)

FOIL stands for:

First

Outside/Outer

Inside/Inner

Last

This shows you the order in which you multiply the binomials! Let's do it:

First: 4x * 6x = 24x^2

Outside: 4x * -46 = -184x

Inside: -10 * 6x = -60x

Last: -10 * -46 = 460

24x^2 - 184x - 60x + 460

Now, we combine like terms to simplify it to the farthest:

24x^2 - 244x + 460

That's it! Hope I helped,

-Mary :)

Write an equation for a line that has slope of 4 and y- intercept of 7
grigory [225]

Answer:

y = 4x + 7

Step-by-step explanation:

the equation for a line is y = mx+b

the y intercept is (0,7)

so in the equation x= 0 and y= 7 and the slope is m, thus m= 4

7= (4)(0)+b

now solve for b

7 = 0 +b

7= b

so the equation of the line would be without the x and y points

y = 4x + 7

You are curious about the average number of yards Matthew Stafford throws for each game for the Detroit Lions. You randomly sele
Damm [24]

Answer:

The margin of error for this estimate is of 14.79 yards per game.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

T interval

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 20 - 1 = 19

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.95}{2} = 0.975. So we have T = 2.093

The margin of error is:

M = T\frac{s}{\sqrt{n}}

In which s is the standard deviation of the sample and n is the size of the sample.

You randomly select 20 games and see that the average yards per game is 273.7 with a standard deviation of 31.64 yards.

This means that n = 20, s = 31.61

What is the margin of error for this estimate?

M = T\frac{s}{\sqrt{n}}

M = 2.093\frac{31.61}{\sqrt{20}}

M = 14.79

The margin of error for this estimate is of 14.79 yards per game.
