Answer:
<em>d</em> = 24.63
Step-by-step explanation:
82.53 - (21.7 + 17.3 + 18.9) =
24.63
Answer:
h=5
Step-by-step explanation:
18x2 = 36
36/6 = 6
6 = h+1
h=5
Check:
5+1 = 6
6x6 = 36
36/2 = 18
The z-score is the number of standard deviations from the mean. For a given x-value, mean (μ), and standard deviation (σ) the z-score is given by
... z = (x -μ)/σ
(a) x=196, μ = 180, σ = 8 gives a z-score of
... z = (196 -180)/8 = 16/8
... z = 2.0
(b) The area associated with x=2 is 0.4772
(c) Rounded to the nearest thousandth, this is 0.477
(d) Carl's subtraction gives
... 0.50 - 0.477 = 2.3%
No it’s not -7 it’s = 2x + 20
i hope it helps!
Answer: 
Step-by-step explanation:
Observe the picture attached.
Find the value of "x" and "y" using the Pythagoren Theorem:

If you solve for "a":

Where "a" is the hypotenuse and "b" and "c" are the legs.
In this case, for "x" you know that:

Then, the value of "x" is:

For "y" you can see that:

Subsituting values and solving for h, you get:
