Answer:
22
Step-by-step explanation:
Basically you can think of Devaughn as 3x and Sydney as 1x, which gives you 4x=88. 88/4= 22, so Sydney is 22
Answer: the answer is D
Step-by-step explanation:
20+25= 45 minutes already used up. there are 120 minutes in 2 hours that she has.
120-45= 75
75/120= .625
.625x100 to get you your percentage = 62.5%

Give me 100 points and ill answer it
Step-by-step explanation:
Translation 5,2
We will use <span>y-y1=m(x-x1), where m= f '(x)= 4x^3e^-x - x^4e^-x, f ' (1) =3e^-1
</span>f (1) =4e^-1
so the equation of tangent line tothe curve at the point <span>(1,1/e) is
y= </span>3e^-1(x-1) + 4e^-1, or y= 3e^-1(x)) + e^-1,
P(Larger or blue) = 7/10. In a bag we have blue and red marbels, which are large and small as in the table shown in the image, the probability of taking a large or blue marble is 7/10.
The key to solve this problem is find the probability of the union events using the equation P(A∪B) = P(A) + P(B) - P(A∩B).
For this problem we have P(Large or Blue) = P(Large) + P(Blue) - P(Large and Blue). The total of the large ones is 25 and the small ones is 15, meaning that the sum of both is 40. P(large) = 25/40, P(Blue) 20/40, and P(Large and Blue) = 17/40
P(Large or Blue) = 25/40 + 20/40 - 17/40 = 28/40 dividing by 4 both terms of the fraction.
P(large or Blue) = 7/10
