Answer:n=-t+m
Step-by-step explanation:
Answer: A
Step-by-step explanation:
because i nsaid sooooo
A mountaineer climbed 1000 feet at a rate of x feet/hour
1000 = x ( t 1 ) eq1
5000 = X ( t 2) eq2 ( he climbed additional at different rate )
the rate was 10 feet / hour less than twice the first rate
X = 2x - 10 eq3
take eq1 and eq 2
( total time = t 1 + t 2 = T)
T = 1000/x + 5000/X
but X = 2x-10
T = 1000/x + 5000/( 2x -10)
T = 1000/x + 5000/( 2(x-5))
T = 1000/x + 2500 / (x-5)
Answer:
I prefer solving problens with fractions because it's easier to add them and you can turn them in to mixed numbers. Hope this helps you!
| Red |Green | Brown Total
<span>Smile |0.100 | .300 | .10 0.50</span>
<span>No smile |0.200 | .150 | .15 0.50
Total 0.30 0.45 0.25 1.00
The probability of choosing red candy is 0.10
The probability of choosing no smile candy is 0.50
The probability of choosing red or no smile = 0.10 + 0.50 = 0.60
I did not use 0.30 as the probability of red because it included the no smile candy. It should only be red candy that has a smile.</span>
