Step-by-step explanation:
The question is incomplete since they do not give information about the Car type 3.
We will do it in a generic way, we will say that the Car type 3 has a mean of M and a standard deviation SD.
We would be:
P (CT3 <550) = P [z <(550 - X) / SD]
Now if we give it values, for example that X = 600 and SD = 120
It would remain:
P (CT3 <550) = P [z <(550 - 600) / 120]
P (CT3 <550) = P [z <-0.42]
We look for this value in the normal distribution table (attached) and it shows us that the probability is approximately 0.3372, that is, 33.72%
What you need to do is replace the X and SD values of theCar type 3 in the equation above how I just did and you will get the result.
Answer: green shirts = 6
Blue shirts = 11
Yellow shirts = 4
Red shirts = 7
Step-by-step explanation:
Red shirts = 7
Let green shirts be x.
There are 5 more blue shirts than green shirts. This means:
Blue shirts = x + 5
There are 2 fewer yellow shirts than green shirts. This means:
Yellow shirts = x - 2
There are 28 shirts in total
Red + blue + yellow + green = 28
7 + (x + 5) + (x - 2) + x = 28
7 + x + 5 + x - 2 + x = 28
10 + 3x = 28
3x = 28 - 10
3x = 18
x = 18/3
x = 6
There are 6 green shirts
Blue shirts = x + 5 = 6 + 5 = 11
Yellow shirts = x - 2 = 6 - 2 = 4
Red shirts = 7
Wouldn't you use sin, cos, tan?
He would have $750 at the end of three weeks
500 + 200 = 700 700 x 2 + 1400
1400 - 650 = 750
$750 at the end of three weeks
