D and E because they are both colder than -10
Answer:
125
Step-by-step explanation:
To find the expected number of black marbles, take the probability of getting a black marble times the number of marbles drawn
P(black) * 200
5/8 *200
125
We should expect 125 black marbles
Answer:
19.5
Step-by-step explanation:
3r+(7+8)/(t-3)
3(4)+(15)/(5-3)
12+(15/2)
12+7.5
19.5
Answer:
Although I'm not entirely sure of the question (sorry lol), any ratio that is 1.5:2 , 6:8 , 9:12 , 12:18 etc would be equivalent to 3 to 4.
Step-by-step explanation:
If you divide both 3 and 4 by 2 you'd wind up with 1.5 ( 3 ) and 2 ( 4 ). When multiplying, you'd get 3x2 = 6 and 4x2=8, 3x3 = 9 and 4x3 = 12 and so on.
Answer:
123
Step-by-step explanation:
A+C and E+G will equal 180 separately. Because the lines are parallel we can see that C is equal to G so we can exchange them. Next we have to fill in an equation by using the two equations given which would be 180=9x+15+5x-3 Now solve it
Add alike terms: 180= 14x+12
Subtract 12 to both sides to get operations alone: 168=14x
divide by 14 to get X alone which is 12=x
Now fill in x
9(12)+15= 123
