Hard to awnser a question if i cant understand what you are saying

Ms. McClain conducted an experiment
joja [24]

Answer:  1

Step-by-step explanation:

Experimental probability is the actual result you get from an experement.

Theoretical probability is the change that you will get that result.

(for example: flipping a coin, the Theoretical probability is 50/50 but after testing the Experimental probability might be 47/53)

therefore,

1/6 is the Theoretical probability because you are using a six-sided number cube.

for the Theoretical probability and the Experimental probability to be the same, the fraction of the roll must equal 1/6.

1/6 equals 8/48.

therefore, since the numbers 1 and 6 were both rolled 8 times out of 48 they are consistant with the Theoretical probability of 1/6.

6 is not one of the answer choices listed so 1 must be your answer.

Cotθ= tan30° find theta
scoundrel [369]

Answer:

60

Step-by-step explanation:

Cot is the same as 1/tan so:

1/tan(theta) = tan(30)

By rearranging the equation, we get:

1/tan(30) = tan(theta)

By taking the inverse tan, we get:

theta = tan^-1 (1/tan(30)) =60

Damm [24]
The conclusion that is valid based on the result of the test would be : A. Her students on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated

we can see in the statement that the average student only need about 25 minutes to take the quiz

hope this helps

PLS HELP ME ON THIS QUESTION I WILL MARK YOU AS BRAINLIEST IF YOU KNOW THE ANSWER!!
Taya2010 [7]

Answer:

The distribution is <u>positively skewed</u>.

Step-by-step explanation:

It's not symmetric because the distribution in the chart isn't equally shown or marked. It's not negative skewed either because for it to be negative the graph would have to go down in a negative direction, usually the left, but in the picture you posted the graph is going down in the right direction. Lastly, positively skewed graphs or charts look like the one you posted. They go down in the right direction, hence why they're called "positively" skewed. The right tail of the distribution is longer in positively skewed graphs or charts.
