Answer: normally distributed and will have a mean that will be approximately equal to the population mean.

Step-by-step explanation: The central limit theorem tries to show that regardless to the variables in a statistical distribution,the sample mean will tend toward approximating the mean of the population for sufficiently large sample size, a sample size or observations that are greater than or equal to 30 is sufficiently large enough.

The theorem helps to understand that as the sample size increases the chances of getting a sample mean that is approximately Equal to the population mean will be high, and the variance will continue to reduce.

Carlos has a fair die and a number cube. He will flip the fair die one time and roll the number cube one time. What is the proba
saul85 [17]

Answer: 0.42 and 5 outcomes.

Step-by-step explanation:

i guess that carlos has a fair coin and a number cube.

the probability can be calculated as the number of outcomes that we want divided the total number of outcomes.

The coin has two possible outcomes, heads and tails, then the probability of getting heads is p1 =1/2

the number cube has 6 numbers, 5 of those 6 numbers are greater than 1, then the probability of getting a number greater than 1 is p2 =5/6

the joint probability is the product of those two:

P = 1/2*5/6 = 5/12 = 0.42

The combinations that include heads and number greater than 1 are 5 combinations:

Heads and 2

Heads and 3

Heads and 4

Heads and 5

Heads and 6.

Can someone help me on this​
Morgarella [4.7K]

Answer:

m∠A = 91°

Step-by-step explanation:

∠A ≅ ∠B (Vertical Angle Theorem). This means that the two angles will have the same measurements.

Note that a straight line = 180° (Definition of a Straight Line).

Find the value of m∠B.

180 - 47 - 42 = m∠B

m∠B = 180 - (89)

m∠B = 91°

Remember that ∠B & ∠A are vertical angles, so they will have the same measurement.

m∠A = 91°
