Javi has a bag of marbles that are identical in size. He has 6 red, 4 blue, 7 yellow, and 3 orange marbles. Javi conducted a probability investigation by drawing a marble out of a bag without looking, recorded the color in the chart below, and returned the marble. Which of the following statements are true? Based on the experimental data, Javi is expected to draw a red marble 30 times out of 100.

Based on the experimental data, Javi is expected to draw a yellow marble 70 times out of 200 draws.

Based on the theoretical probability, Javi is expected to draw a blue marble 40 times out of 150.

Based on the theoretical probability, Javi is expected to draw an orange marble 50 time out of 250 draws.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
