1. find the greatest common factors of the numerator & denominator
2. regroup the factors to make fractions equivalent to 1
3. multiply the remaining factors
Answer:
2/13
Explanation:
The bag has 6 red, 3 green, 4 blue.
Total marbles = 13
Probability of getting <u>blue the first time</u> would be 4/13 because 4 of the 13 total marbles are blue
Because you're not putting back the first marble, the total would go down to 12, so the probability of getting <u>red the second time</u> would be 6/12 or 1/2
The probability that the first marble is blue and the second marble is red = (4/13)(6/12) = 2/13
<em><u>a=1. </u></em>to do this you subtract 2 from both sides to isolate x. then divide both sides by 5 to get x = ?
Answer:
n = 1537 represent the sample size of American over 46
X = 1537-1245=292 represent the number of Americans over 46 who smoke
And for this case in order to estimate the population proportion we can use this formula:
Where:
X represent the number of people with the characteristic desired and n the sample size. If we replace we got:
Step-by-step explanation:
For this case we deine the parameter of interest p as the proportion of Americans over 46 who smoke.
We know the following info provided:
1245 people don't smoke
n = 1537 represent the sample size of American over 46
X = 1537-1245=292 represent the number of Americans over 46 who smoke
And for this case in order to estimate the population proportion we can use this formula:
Where:
X represent the number of people with the characteristic desired and n the sample size. If we replace we got:
Answer: hi im mongraal
Step-by-step explanation:
In mathematics, a cube root of a number x is a number y such that y³ = x. All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted ³√8, is 2, because 2³ = 8, while the other cube roots of 8 are −1 + √3i and −1 − √3i. The three cube roots of −27i are 3i, 3√(3)/2-3/2i, and -3√(3)/2-3/2i.
