Answer: The angles all add up to 180 degrees, the triangle is obtuse, and it is an isosceles triangle.

Step-by-step explanation: Since the triangle has angles, 40, 40, and 100, the angles will add up to 180. Also since it has an angle more than 90 degrees, the triangle is obtuse. Finally it has two equal sides, so it is a an isosceles triangle. It does not have all equal side lengths, so it is not an equilateral triangle. Also the triangle does not have all different side lengths so it is not a scalene triangle. Finally, the triangle does not have any acute angles (angles under 90 degrees) so the triangle is not acute.

In a certain country, the average age is 31 years old and the standard deviation is 4 years. If we select a simple random sample

KengaRu [80]

Answer: 0.0062

Step-by-step explanation:

Given : Mean : $\mu=\ 31$

Standard deviation : $\sigma= 4$

Sample size : $n=100$

Assume that age of people in the country is normally distributed.

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For x = 32

$z=\dfrac{32-31}{\dfrac{4}{\sqrt{100}}}=5$

The p-value = $P(x\geq32)=P(z\geq5)$

$=1-P(z$

Hence, the the probability that the average age of our sample is at least =0.0062

I promise i will mark as brainiest

Katyanochek1 [597]

Answer:

A

Step-by-step explanation:

$\frac{2003}{n} = z + \frac{23}{n}$

where z is an integer

$2003 = nz + 23$

$nz = 1980$

$nz = {2}^{2} \times {3}^{2} \times 5 \times 11$

possible values of n

n= {1980, 990, 660, 495, 396, 330, 198, 180, 165, 132, 99, 90, 60, 45, 36, 30, 20, 18, 15, 5, 3}

cardinality of n=21
