Answer:
The probability that the sample proportion is within 0.03 of the population proportion is 0.468.
Step-by-step explanation:
The complete question is:
A company makes auto batteries. They claim that 84% of their LL70 batteries are good for 70 months or longer. Assume that this claim is true. Let p^ be the proportion in a random sample of 60 such batteries that are good for 70 months or more. What is the probability that this sample proportion is within 0.03 of the population proportion? Round your answer to two decimal places.
Solution:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
The information provided is:
As the sample size is large, i.e. <em>n</em> = 60 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion of LL70 batteries that are good for 70 months or longer.
Compute the probability that the sample proportion is within 0.03 of the population proportion as follows:
Thus, the probability that the sample proportion is within 0.03 of the population proportion is 0.468.

A line can intersect a circle twice. So, two lines intersect one circle 4 times. Two lines can intersect two circles 8 times.
Hope this helps!
The number 1934 can be written as:
1,000 + 900 +30 +4
so the value of the 3 is 30, of the 9 is 900 and of the 1 is 1000.
900 is indeed 10 times 30, so
"<span>the value of the 9 in the hundreds place ten times the value of the 3 in the tens place</span>"
Answer: true
Answer:
Exactly one triangle exists with the given conditions, and it must be an isosceles triangle.

Step-by-step explanation:
Let be the measure of one angle in our triangle; since we have two equal angles in our triangle, their measure will be .
We know from our problem that at least one angle of our triangle measure 52°; since the sum o the interior angles of a triangle is 180°, we can use an equation to relate the quantities and solve for to find the measure of the tow equal angles:
Now how know that the measure of the angles of our triangle are 52°, 64°, and 64°. Since we have tow equal angles in our triangle, we can conclude that our triangle is isosceles. Notice that we don't have any given side, so the sides of our isosceles triangle can vary in length.
We can conclude that the correct answer is: C. Exactly one triangle exists with the given conditions, and all instances must be isosceles triangles.
