The table shows ordered pairs of the function y = 8 - 2x. When x = 8, the value of y is ?

1 answer:

6 0

Substitute the value of x into the expression,
y = 8 - 2x
y = 8 - 2(8)
y = 8 - 16
y = -8

In short, Your Answer would be -8

Hope this helps!

Answer:

Z-score is 1.75

Step-by-step explanation:

$1 - 0.9599 = 0.0401$

You can find the Z-score from the standard normal table. Just read the table in reverse.

In this case, Z = 1.75

The amounts of nicotine in a certain brand of cigarette are normally distributed with a mean of 0.917 g and a standard deviation

Nutka1998 [239]

Answer:

$z = \frac{0.872-0.917}{\frac{0.303}{\sqrt{37}}}= -0.903$

And we can find this probability to find the answer:

$P(z$

And using the normal standar table or excel we got:

$P(z$

Step-by-step explanation:

Let X the random variable that represent the amounts of nocatine of a population, and for this case we know the distribution for X is given by:

$X \sim N(0.917,0.303)$

Where $\mu=0.917$ and $\sigma=0.303$

We have the following info from a sample of n =37:

$\bar X= 0.872$ the sample mean

And we want to find the following probability:

$P(\bar X \leq 0.872)$

And we can use the z score formula given by;

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

And if we find the z score for the value of 0.872 we got:

$z = \frac{0.872-0.917}{\frac{0.303}{\sqrt{37}}}= -0.903$

And we can find this probability to find the answer:

$P(z$

And using the normal standar table or excel we got:

$P(z$

JUST DO 6 and 22 pleasss!!!

Hatshy [7]

Answer:

Step-by-step explanation:

x=intercept is when the line intersect with the x axis when y=0

6: x intercept (1,0)

y intercept is when the line intersect with y axis at certain point or when x=0

y intercept (0.-24)

22: (8,0) x intercept

(0 , 4) the y-intercept
