What is the y-intercept for the equation y = 11x + 1?

Mathematics

Answer:

Y-intercept = 1

Step-by-step explanation:

To find the y-intercept you have to find where x = 0.

Plug this into the equation and solve to find the y-intercept:

y = 11(0) + 1

y = 0 + 1

y = 1

Thus, the y-intercept would be 1.

Also, when written in the slope-intercept form the y-intercept is always the lone number with no x with it.

So in the equation y = 11x + 1. You can see where the y-intercept is (the 1).

Hope this helps!!

Answer:

(0, 1)

Step-by-step explanation:

<u>Step 1:  Determine the y-intercept</u>

Using the slope intercept form, we know that the equation is y = mx + b where m is the slope and b is the y-intercept.  Therefore, looking at our equation, we can tell that b is 1 therefore the y-intercept is (0, 1)

Answer: (0, 1)

The length of human pregnancies from conception to birth varies according to an approximately normal distribution with a mean of
Varvara68 [4.7K]

Answer:

A) 68.33%

B) (234, 298)

Step-by-step explanation:

We have that the mean is 266 days (m) and the standard deviation is 16 days (sd), so we are asked:

A. P (250 x < 282)

P ((x1 - m) / sd < x < (x2 - m) / sd)

P ((250 - 266) / 16 < x < (282 - 266) / 16)

P (- 1 < z < 1)

P (z < 1) - P (-1 < z)

If we look in the normal distribution table we have to:

P (-1 < z) = 0.1587

P (z < 1) = 0.8413

replacing

0.8413 - 0.1587 = 0.6833

The percentage of pregnancies last between 250 and 282 days is 68.33%

B. We apply the experimental formula of 68-95-99.7

For middle 95% it is:

(m - 2 * sd, m + 2 * sd)

Thus,

m - 2 * sd <x <m + 2 * sd

we replace

266 - 2 * 16 <x <266 + 2 * 16

234 <x <298

That is, the interval would be (234, 298)

Complete the square for 3x^2-12x=9
larisa [96]

Answer:

The solutions are -0.65 and 4.65.

Step-by-step explanation:

3x^2 - 12x = 9

Divide both sides by 3

x^2 - 4x = 3

To make a square with "x^2 - 4x", you need to have a "+ 4" after it so it can be simplified as (x-2)^2.  So add 4 to both sides.

x^2 - 4x + 4 = 7

(x-2)^2 = 7

x - 2 = (square root) of 7

x = 2 (+/-) (square root) of 7.

x = {-0.65, 4.65}

The solutions are -0.65 and 4.65.

hope this helps:)sorry if it doesnt
