Answer:
Below
Step-by-step explanation:
You can use Pythagorean theorem to find the hypotenuse of a right triangle.
a2 + b2 = c2
The square root of 15 = 3.8729.... (a bunch of other numbers)
4^2 + 3.8729^2 = c2
16 + 15 = 31
Now that you have this, you need to find the square root
The square root of 31 = 5.56775436
Rounding this to the tenth it would be: 5.57
Final answer: C = 5.57
hope this helps! :)
Divide each side of the inequality by 16 .
Answer:
![- 4.4c + 1.1](https://tex.z-dn.net/?f=%20-%204.4c%20%2B%201.1)
Step-by-step explanation:
Combine like terms:
-5.8c and +1.4c gives us -4.4c
+4.2 and -3.1 gives us 1.1
Put them together, and you have your expression.
Step-by-step explanation:
D=37.68
R=d/2 = 37.68/2 =18.84
Volume of sphere = 4/3 πr3
Now,
4/3*22/7*(18.84)3
=88/21*6687.17
=588470.96/21
=28022.42 mm3. ☑️
Part (a)
The raw score is x = 25. The mean and standard deviation are mu = 45 and sigma = 13.8 respectively.
The z score is computed with the formula below
z = (x-mu)/sigma
z = (25-45)/13.8
z = -1.449275 approximately
z = -1.45 is the final answer
========================================================
Part (b)
We want the z score to be larger than 2. So z > 2.
This is the same as wanting the expression (x-mu)/sigma to be larger than 2
(x-mu)/sigma > 2
(x-45)/13.8 > 2
x-45 > 2*13.8
x-45 > 27.6
x > 27.6+45
x > 72.6
If a customer's age is greater than 72.6 years, then this means they have a z score greater than 2. We can say they are more than 2 standard deviations above the mean.
If you need a whole number, then I'd round up to 73. Or you could pick any age larger than this.
