How many whole servings of 3/4 cups are in 3 1/2 cups of ice cream?

1 answer:

6 0

Well, what you're going to do is.. turn 3 1/2 into an irregular fraction.

3 = 6/2
we still have the initially 1/2 left so we will add that.
7/2

now we want to change it so that the denominator is equal to 4 so we multiply both top and bottom by 2

14/4

now we divide the 14 by 3 and you will get approximately 4. we will ignore the rest because it asks for whole servings and 3 only goes nicely into 14 4 times

George has a spinner with three equal sections colored orange, blue, and white. He spins the spinner 100 times. What is the expe

Answer:

1/3

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Experimental probability is based on the result of an experiment that has been carried out multiples times

probability of landing on the orange section = proportion of the orange section / total proportions of all the colours

= 1/3

This is for AP CALCULUS. I really need help on this. I’m trying to find the first and second derivative of these three functions

ale4655 [162]

Review Material:

$\sqrt[n]{x^m} = x^{\frac{m}{n}}$

$\frac{d}{dx}[x^n]=nx^{n-1}\\$

$\frac{d}{dx}[\sin(x)]=\cos(x)\\$

$\frac{d}{dx}[\cos(x)]=-\sin(x)\\$

$\frac{d}{dx}[constant]=0\\$

Step-by-step explanation:

(a)

$F(x) = -2\cos(x) +x^{\frac{4}{3}} -3e\\ \text{Note: 3e is a constant}\\F'(x) = 2\sin(x) + \frac{4}{3}x^{\frac{1}{3}}\\F''(x) = 2\cos(x) + \frac{4}{9}x^{-\frac{2}{3}}$

(b)

$F(x) = x^{-3} + \frac{1}{2}x^2-\sin(x)\\F'(x)=-3x^{-4} + x - \cos(x)\\F''(x) = 12x^{-5} + 1 + \sin(x)$

(c)

$F(x) = 2x^{-3}+x^{\frac{3}{4}}-4x\\F'(x) = -6x^{-4} + \frac{3}{4}x^{-\frac{1}{4}}-4\\F''(x)= 24x^{-5} - \frac{3}{16}x^{-\frac{5}{4}}$
