Y is inversely proportional to X.<br><br> When y<br><br> 20, x = 2<br><br> Work out y when x = 5
Oliga [24]

Answer:

When x = 5, y = 8.

Step-by-step explanation:

y is inversely proportional to X.

This means that we solve this using the rule of three for inversely proportional variables, that is, we apply line multiplication instead of cross multiplication.

y = 20, x = 2

Work out y when x = 5

20 - 2

x - 5

Applying line multiplication

5y = 40

y = \frac{40}{5}

y = 8

When x = 5, y = 8.

107,600 115,220 104,910 median, mode, mean
san4es73 [151]

Answer:

<u>1. Mean =  342.7 (Rounding to the nearest tenth)</u>

<u>2. Median =  167.5 </u>

<u>3. Mode = There isn't a mode for this set of numbers because there isn't a data value that occur more than once. </u>

Step-by-step explanation:

Given this set of numbers: 107, 600,  115, 220,  104, 910, find out these measures of central tendency:

1. Mean = 107 + 600  + 115 + 220 + 104 + 910/6 = <u>342.7</u> (Rounding to the nearest tenth)

2. Median. In this case, we calculate it as the average between the third and the fourth element, this way:

115 + 220 =335

335/2 = <u>167.5 </u>

3. Mode = <u>There isn't a mode for this set of numbers because there isn't a data value that occur more than once. All the data values occur only once.</u>

Amanda increased the amount of protein she eats every day from 48g to 54g. By what percentage did Amanda increase the amount of
WINSTONCH [101]

Answer:

Explanation:

The formula for calculating the percent change is:

p=N−OO⋅100

Where:

p is the percent change - what we are looking for

N is the New Value - 54g for this problem

O is the Old Value - 48g for this problem

Substituting and calculating p gives:

p=54−4848⋅100

p=648⋅100

p=60048

p=12.5
