Given the points (0,1) and (-2,5) and on a line, find its equation in the form y= mx+b.

AnnZ [28]

Answer:

the desired equation is y = -2x + 1

Step-by-step explanation:

As we go from (-2, 5) to (0, 1), x increases by 2 and y decreases by 4. Thus, the slope of this line is m = rise / run = -4 / 2, or m = -2.

Starting with y = mx + b, insert the knowns:

1 = -2(0) + b. Then b = 1, and the desired equation is y = -2x + 1.

The height distribution of NBA players follows a normal distribution with a mean of 79 inches and standard deviation of 3.5 inch

Shtirlitz [24]

Answer:

The probability will be "0.0111".

Step-by-step explanation:

The given values are:

Mean,

$\mu$ = 79

Standard deviation,

$\sigma$ = 3.5

Now,

⇒ $\sigma\bar x = \frac{\sigma}{\sqrt n}$

$= \frac{3.5}{\sqrt 16}$

$=0.875$

⇒ $P(\bar x > 81) = 1 - P(\bar x < 81)$

So,

= $1 - P{\frac{(\bar x - \mu \bar x )}{ \sigma \bar x} < \frac{(81 - 79) }{0.875} ]$

= $1 - P(z < 2.2857)$

= $0.0111$
