<span>First we calculate z using the formula:
z = (x - μ)/σ</span>
Where:
x = our variable, 10
μ = mean, 8
σ = standard dev, 2
Substituting known
values:<span>
z = (10 - 8)/2
z = 2/2
z = 1
Using the tables of
the normal distribution to find the p-value with z = 1
p = 0.8413
Since we want
"greater than 10”, we need to subtract the probability from 1
therefore
p* = 1 - 0.8413 = <span>0.1587</span></span>
Answer: Choice D
Explanation:
We have the two points (2,2) and (2,-2) which have a repeated x coordinate. This is not allowed if we wanted a function. A function must have any x input lead to exactly one and only one output (assuming the input is in the domain).
Answer choice E is the correct answer.
Answer:
radius of circle = 3cm
circumference = 18.84cm
diameter = 6cm
Step-by-step explanation:
if the diameter of circle is 6cm
radius of circle = diameter/2
= 6/2
= 3
circumference of circle = 2
r
= 2 x 3.14 x 3
= 6.28 x 3
= 18.84

Best to write this problem as shown below:
<span>562.34
-64.89
----------- First, estimate the correct answer. It would be 562-65 = 497.
Must borrow from the tenths column, because 9 is greater than 4. We end up with 5 under the 4 and 9. We must borrow again to obtain the next digit:
12-8=4, so the result is now .45
11-4=7, so the result is now 7.45
55-6=9, so the result is now 97.45.
Finally, 4-0=4, so the final result is 497.45. Compare this to the estimate (497).
Here we've had to borrow 4 times.</span>
