Pq= 10.5, qr=31.5, rs=10.5, sp=31.5
Yes 12/15 can be simplified.
To simplify 12/15 find the greatest common multiple. The <span> greatest common multiple of 12/15 is 3. Now divide 12/15 by 3.
</span>
12 ÷ 3 = 4
15 ÷ 3 = 5
4/5 is the simplified version of 12/15
Where's the system? I can't answer your question without it.
Answer:
48 degrees
Step-by-step explanation:
Angle 2 is a right angle.
Right angles are 90 degrees.
A line is 180 degrees.
Angle 1, 5, and 2 form a line.
180-90=90
That means that Angles 1 and 5 add up to 90 degrees.
We know that Angle 3 is 42 degrees.
Angle 3 and 5 are Vertical angles.
Vertical angles are always congruent.
This means that Angle 5 is also 42 degrees.
As we discussed earlier, Angles 1 and 5 are complementary. (Add up to 90 degrees)
42+x=90
Subtract 42 from both sides.
x=48
m<1=48
Answer:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample mean, with a large sample size, can be approximated to a normal distribution with mean and standard deviation 
.
This is valid no matter the shape of the population.
So the correct answer is:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
