Answer:
-6.134 to +6.134
Step-by-step explanation:
given that a large population of variable x is characterized by its known mean value of 6.1 units and a standard deviation of 1.0 units and a normal distribution
X is Normal with mean =6.1 and std dev = 1 unit
We are to determine the range of values containing 70% of the population of x
We know that normal distribution curve is bell shaped symmetrical about the mean.
So to find 70% range we can use 35% on either side of the mean
Using std normal distribution table the value of z for which probability from 0 to z is 0.35 is 1.034
Hence corresponding x value is
i.e. 70% values lie between
-6.134 to +6.134

Answer:
I would say B) approx. 35
Step-by-step explanation:
Because that is so close to 45 degrees which is closest to 35
<h3><u>
Answer:</u></h3>
<h3><u>
Step-by-step explanation:</u></h3>
<u>We can clearly see that the triangle is an isosceles triangle. This also means that y must equal to 180 - 115. Let's solve.</u>
- => x + y + 180 - 115 = 180
- => x + y + 65 = 180
<u>Since 180 - 115 equals 65, this means that </u><u>y = 65.</u>
- => x + 65 + 65 = 180
- => x + 130 = 180
- => x = 180 - 130
- => x = 50
<h3><u>Conclusion:</u></h3>
<u>Therefore, our answers are:</u>
Hoped this helped.
Answer:
Length arc AB = 3.14 in
Step-by-step explanation:
Length of arc AB = central angle/360 * 2πr
Central angle = 30°
Radius (r) = 6 in.
Substitute
Length of arc AB = 30/360 * 2*π*6
Length arc AB = 3.14 in. (Nearest tenth)
