<span>0.4332
The problem is asking what proportion of a normal distribution is within 1.50 standard deviations on the positive half of the curve. So let's take a look. First thing is to figure out what would be a reasonable answer. Looking at the standard deviation, there will be 34.1% within 0 to +1 standard deviations. And there will be 47.7% within 2 standard deviations. So the correct answer will be something between 0.341 and 0.477. So let's look at the possible answers.
​0.4332 - This answer falls within the desired range. It's a candidate.
​0.8664 - This answer is way too large. Well over 50%, so it can't work.
​0.0668 - This answer is way too small. So once again, it can't work
​0.9332 - If the 0.8664 above was too large, imagine how unreasonable this answer is. Also wrong.
So of the 4 available choices, only 0.4332 is possible. So that's the correct answer.</span>
Answer:
measure or arc BAC should be 297 degrees (with assumptions)
Step-by-step explanation:
Assumption 1: the cap Z in your question is actually an angle symbol
Assumption 2: A is the center of the circle
IF these assumptions are true, then the measure of arc BAC is 36 - 63 = 297 degrees
Answer:
A. 3/8*2=6/8
Step-by-step explanation:
Think about a whole number as (whole number)/1
(2/1)
Then multiply
3/8*2/1=6/8
Hope that helps!
Answer:
See below in bold.
Step-by-step explanation:
a. |x| = 6
x = 6, -6.
b. |x − 5| = 4
x - 5 = 4
x = 9.
x - 5 = -4
x = 1.
c. 2|x + 3| = −10
No solution because |x + 3| is an absolute value so is always positive.
