Answer:

Each person gets $\frac{7}{8}$ cup of pudding.

Step-by-step explanation:

The problem is essentially asking;

$3\frac{1}{2}$ ÷ 4

(4 because the pudding has to be divided amongst Regina and her 3 friends, hence 4 people)

To divide fractions, first one has to convert from improper fractions to mixed numbers;

$\frac{7}{2}$ ÷ 4

Next, one has to reciprocate the second fraction, since the second number is an integer, one simply has to put the number as the denominator, and set the numerator to 1.

$\frac{7}{2}$ * $\frac{1}{4}$

Now, one has to perform the multiplication, simply multiply the numerators and denominators together (there is no way of simplifying in this problem);

$\frac{7}{8}$

Each person gets $\frac{7}{8}$ cup of pudding.

If 5-y^2=x^2 then find d^2y/dx^2 at the point (2, 1) in simplest form.

ratelena [41]

Answer:

y"(2, 1) = -5

Step-by-step explanation:

Step 1: Define implicit differentiation

5 - y² = x²

Step 2: Find dy/dx

Take implicit differentiation: -2yy' = 2x
Isolate y': y' = 2x/-2y
Isolate y': y' = -x/y

Step 3: Find d²y/dx²

Quotient Rule: y'' = [y(-1) - y'(-x)] / y²
Substitute y': y" = [-y - (-x/y)(-x)] / y²
Simplify: y" = [-y - x²/y] / y²
Multiply top/bottom by y: y" = (-y² - x²) / y³
Factor negative: y" = -(y² + x²) / y³

Step 4: Substitute and Evaluate

y"(2, 1) = -(1² + 2²) / 1³

y"(2, 1) = -(1 + 4) / 1

y"(2, 1) = -5/1

y"(2, 1) = -5

A merchant mixed 10 lb of a cinnamon tea with 2 lb of spice tea. The 12-pound mixture cost $13. A second mixture included 16 lb

Sonja [21]

Step-by-step explanation:

Let's say c is the price of cinnamon tea, and s is the price of spice tea.

10c + 2s = 13

16c + 8s = 28

Divide the second equation by 4:

4c + 2s = 7

Subtract from the first equation:

6c = 6

c = 1

Use any equation to find s.

s = 1.5

Therefore, the cinnamon tea costs $1 per pound and the spice tea costs $1.50 per pound.

Alan recorded the points he scored on the basketball court in ms2 school yard. What is the mean absolute deviation of his scores

Alecsey [184]

Answer:

The mean absolute deviation is: 7.44

Step-by-step explanation:

Given

$Scores: 98, 78, 84, 75, 91$

Required

The mean absolute deviation

First, calculate the mean

$\bar x = \frac{\sum x}{n}$

$\bar x = \frac{98+78+84+75+91}{5}$

$\bar x = \frac{426}{5}$

$\bar x = 85.2$

The mean absolute deviation (M) is:

$M = \frac{1}{n}\sum|x - \bar x|$

So, we have:

$M = \frac{1}{5}(|98 - 85.2|+|78 - 85.2|+|84 - 85.2|+|75 - 85.2|+|91 - 85.2|)$

$M = \frac{1}{5}(|12.8|+|-7.2|+|-1.2|+|-10.2|+|5.8|)$

Remove absolute brackets

$M = \frac{1}{5}(12.8+7.2+1.2+10.2+5.8)$

$M = \frac{1}{5}*37.2$

$M = 7.44$
