For the graphing if for example it says (3,-9) then you start at the very middle called the origin. Then go to the right 3.(this is called the x-axis) then go down 9 (this is the y axis) stop there and put you point. I hope this kinda helps explain this to you better :/

Assume that X is Normal with mean $ 240 and standard deviation $60 . the probability that , in a randomly selected week , Dan wi

enyata [817]

Answer:

The probability of Dan making less than $255 is 0.5987 or 59.87%

Step-by-step explanation:

Given that:

Mean = μ = $240

SD = σ = $60

We have to find the probability that Dan will make less than $255

First of all, we have to find the z-score of 255

z-score is denoted by z and is given by the formula

$z = \frac{x-mean}{SD}$

Here,

x = 255

Putting the values

$z = \frac{255-240}{60}\\z = \frac{15}{60}\\z = 0.25$

Now we have to look at the z-score table to find the probability of 0.25

P(x<255) = 0.5987

Converting into percentage

59.87%

Hence,

The probability of Dan making less than $255 is 0.5987 or 59.87%

1. Find the equation of a line, in point-slope form, that passes through the points (2,3) and (5,7).

Ket [755]

Slope = (7-3)/(5-2) = 4/3

passes through the points (2,3) and (5,7).
so
y = mx + b
3 = 4/3(2) + b
3 = 8/3 + b
b = 3 - 8/3
b = 9/3 - 8/3
b = 1/3

equation
y = 4/3x + 1/3
