4.4.3 Test (CST) Continuous Probability Distributions

Mathematics
1 answer:
Zanzabum3 years ago
8 0

Answer:

B

Step-by-step explanation:

We have that for a normal distribution, the value of z can be calculated using the following formula:

z = (x - m) / sd

where x is the value to evaluate, m the mean and sd the standard deviation, we have those values x = 15.3, m = 17.4 and sd = 3.2

if we replace we have:

z = (15.3 - 17.4) /3.2

z = -0.65625

if we round to 2 decimal places, it would be -0.66, that is, the answer is B.

What is five×fivewhat is the answer for 4 x 5
Mandarinka [93]
Well 
<span>
4 x 5 = 20 

and

5 x 5 = 25

I'm sure a calculator could help you out with this, But if you don't have access to a calculator I'll show you how to multiply. It's just like adding, Let's use 6 x 7 for example. Take the first number ( Which is 6 in this case ) and look at the second number ( Which would be 7 ) The second number represents how many times you would add the first number together. So:

6 + 6 + 6 + 6 + 6 + 6 + 6 = 42 ( We add 6 together 7 times )

So

6 x 7 = 42

There are faster methods but this is probably the best way to start out.

The length of a rectangular pool is 4yds longer than twice the width. If the area is 70 square yards, find the dimensions.
kodGreya [7K]

Answer: Found it by web and solving

Step-by-step explanation: L = W + 4

LW = 60

---

LW = 60

(W + 4)W = 60

W^2 + 4W + (-60) = 0

---

above is in quadratic equation form: ax^2 + bx + c = 0

---

use the quadratic formula to solve for two solutions:

x = ( -b +- sqrt( bb - 4ac ) ) / 2a

---

the two solutions are:

W = 6

W = -10

 

the negative solution doesn't make sense for length, so use the positive solution.

---

L = 10

W = 6
