There are 12 marbles in total. 4 of them are white.
The probability of getting a white marble on the first try is 4/12 or 1/3.
The probability of getting a second white marble in a row? Since you already pulled out a white marble on the first attempt, there are now 3 white marbles and 11 marbles in total. So the probability of getting a white marble at this point is 3/11.
Thus the probability of doing this back to back is 1/3 * 3/11 or 3/33 or 1/11.
The answer is B.
Answer:
P = 4x - 6
Step-by-step explanation:
In a given rectangle, the shorter side is 3 less than the longer side.
Let the longer side is the length of the rectangle L and the shorter side of the rectangle is the width of the rectangle W.
Then from the condition given we can write that L = W + 3 ....... (1)
Now, perimeter of the rectangle is given by P = 2(L + W)
So, from equation (1) we can write P = 2(L + L - 3) {Since W = L - 3}
⇒ P = 2(2L - 3) = 4L - 6.
Now, if we represent L as the variable x, then the expression for perimeter P = 4x - 6 (Answer)
Answer:
The correlation between the Math SAT and the Verbal SAT computed from the data on all the individuals who took the tests would be less than 0.97.
Step-by-step explanation:
Averaging data into blocks (in this scenario, by State) tends to a reduction in variation and an increase in correlation between the studied variables. Therefore, when applying regression to the original individual data, a reduced correlation would be expected:
Therefore, the correlation between the Math SAT and the Verbal SAT computed from the data on all the individuals who took the tests would be less than 0.97.
Answer:
0.143
Step-by-step explanation:
1) convert to decimal form: 0.142857
2) rounding to nearest thousandth (3rd decimal place)
3) number is higher than 5 so it rounds up to 0.143
I think it’s 1 because it looks reasonable
