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
Here,
x = 255
Putting the values
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%

Step-by-step explanation:
Technically, I didn't solve it. I used an algebra calculator online called m a t h w a y. It helps a lot but if you really need to know how to solve it on pencil and paper I cannot help you.
I had to space out the website so it let me submit this answer btw

x=75
Step-by-step explanation:
The triangle is isosceles, meaning that the angles V and U are congruent
4.4 is the answer cause 5.6 plus 4.4 is 10
