5 of the planets are earth like and 2 are mars like
5 * 2 = 10
<u>1 * 2 = 2</u>
Total 12
4 earth like and 4 mars like
Earth = 4*2 = 8
<u>Mars = 4 * 1 = 4</u>
Total 12
3 Like Earth 6 like mars
Earth 3 * 2 = 6
<u>Mars 6 * 1 = 6</u>
Total 12
Those answers are the only ones possible.
The correct answer would be 2y^5
Sam will need 30 rolls of 30 inches of paper
Answer:
1/18
Step-by-step explanation:
there are 12 marbles in the bag
P(choose red) = 2/12 = 1/6
P(choose blue after replacement) = 4/12 = 1/3
P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18
To solve this problem you must apply the proccedure shown below:
1. You have that the <span>data set has SSR=400 and SSE=100
2. Therefore you have </span><span>the coefficient of determination is:
r</span>²=SSR/SSTO
SSTO=SSR+SSE
3. Then, when you substitute the values, you obtain:
SSTO=400+100
SSTO=500
r²=400/500
4. So, you have that the result is:
r²=0.8
Therefore, as you can see, the answer for the exercise shown above is: <span> the coefficient of determination is 0.8</span>
