60% are boys, 40% are girls
Answer:
Step-by-step explanation:
Given that,
f(3) = 2
f'(3) = 5.
We want to estimate f(2.85)
The linear approximation of "f" at "a" is one way of writing the equation of the tangent line at "a".
At x = a, y = f(a) and the slope of the tangent line is f'(a).
So, in point slope form, the tangent line has equation
y − f(a) = f'(a)(x − a)
The linearization solves for y by adding f(a) to both sides
f(x) = f(a) + f'(a)(x − a).
Given that,
f(3) = 2,
f'(3) = 5
a = 3, we want to find f(2.85)
x = 2.85
Therefore,
f(x) = f(a) + f'(a)(x − a)
f(2.85) = 2 + 5(2.85 - 3)
f(2.85) = 2 + 5×-0.15
f(2.85) = 2 - 0.75
f(2.85) = 1.25
1)
a.
60 ounces = 3 pounds
So no, you don’t have as much fruit as you need.
b.
60 ounces —> 3 pounds
X ounces —> 4 pounds
Cross product :
(60 x 4) / 3 —> 240/3 = 80
So in order to have 4 pounds of fruits, you need 80 ounces of fruits.
You already have 60 ounces of fruits.
X + 60 = 80
80 - 60 = X
20 = X
You need 20 more ounces to have 4 pounds of fruits.

Step-by-step explanation:
n(s)=28
n(p)=14
p(p)= n(p)/n(s)
= 14/28
=1/7
