Answer:
yes
Step-by-step explanation:
yes -11/4 is a rational number because it is in the form of p/q . so -11/4is a rational number. hope you understand ,all the best.
we know that
An isosceles triangle has two equal sides and two equal angles
The equilateral triangle has the three equal sides and the three equal angles
so
If a triangle is isosceles cannot be equilateral
therefore
<u>The answer is </u>
False
-25(x-4)=-55(x-10)
-25x+100 = 55x-550 |+25x
100 = 80x-550 |+550
650 = 80x | /80
65/8 = x
x = 8 1/8

Answer:
95% of monsoon rainfall lies between 688 mm and 1016 mm.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 852 mm
Standard Deviation, σ = 82 mm
We are given that the distribution of monsoon rainfall is a bell shaped distribution that is a normal distribution.
68 ‑ 95 ‑ 99.7 rule
- Also known as Empirical rule.
- It states that all data lies within the three standard deviation of the mean for a normal distribution.
- About 68% of data lies within one standard deviation of mean
- About 95% of data lies within two standard deviation of mean.
- About 99.7% of data lies within three standard deviation of mean.
We have to find the monsoon rains fall in the middle 95 % of all years.
By the rule 95% of data lies within two standard deviation of mean.Thus,
Thus, 95% of monsoon rainfall lies between 688 mm and 1016 mm.
Measure of angle K is 146 degrees.
