In a triangle there is 180 degrees

Answer:

<u>D</u>

Step-by-step explanation:

  • The <u>Angle Sum Property of a Triangle</u> states that the internal angles of a triangle add up to 180°
  • Here, the sum is : 130 + 30 + 30 = 190°
  • Therefore, the angle measurements are not correct
  • The total angle measure of triangle should decrease by 10°
  • By making the top angle 120°, the sum becomes 180°
  • Hence, <u>D</u> is the correct option

The number of accidents per week at a hazardous intersection varies with mean 2.2 and standard deviation 1.1. This distribution
cluponka [151]

Answer:

Step-by-step explanation:

Hello!

The definition of the Central Limi Theorem states that:

Be a population with probability function f(X;μ,δ²) from which a random sample of size n is selected. Then the distribution of the sample mean tends to the normal distribution with mean μ and variance δ²/n when the sample size tends to infinity.

As a rule, a sample of size greater than or equal to 30 is considered sufficient to apply the theorem and use the approximation.

X[bar]≈N(μ;σ²/n)

If the variable of interest is X: the number of accidents per week at a hazardous intersection.

There is no information about the distribution of this variable, but a sample of n= 52 weeks was taken, and since the sample is large enough you can approximate the distribution of the sample mean to normal. With population mean μ= 2.2 and standard deviation σ/√n= 1.1/√52= 0.15

I hope it helps!
