babunello [35]

2) 200 mL

3) 0.2 kg

Step-by-step explanation:

In this problem, we know that:

- With 1 liter of juice, we can fill a total of 5 cups

So we know that the total volume of 5 cups is equal to

V = 1 L

This means that the volume of each cup is equal to the total volume divided by the number of cups (5), therefore:

$V_1=\frac{V}{5}=\frac{1L}{5}=0.2 L$

And keeping in mind the equivalence between liters and milliliters:

1 L = 1000 mL

This means that the capacity of each cup is

$V_1=0.2 L \cdot 1000 mL/L = 200 mL$

Here we want to find the mass contained in each cup.

We know that the mass of a substance is related to each volume by the equation

$d=\frac{m}{V}$

where

d is the density

m is the mass

V is the volume

In this problem, we have:

V = 0.2 L is the volume of juice in each cup

$d=1kg/L$ is the density of juice (assuming it is the same as the density of water)

So, the mass of juice in one cup is:

$m=dV=(1)(0.2)=0.2 kg$

Ax+ay+xa+ya Differentiate

Dmitry_Shevchenko [17]

Answer:

2 a

Step-by-step explanation:

Possible derivation:

d/dx(2 a x + 2 a y)

Differentiate the sum term by term and factor out constants:

= 2 a (d/dx(x)) + d/dx(2 a y)

The derivative of x is 1:

= d/dx(2 a y) + 1 2 a

The derivative of 2 a y is zero:

= 2 a + 0

Simplify the expression:

Answer: 2 a

The numbers of pages in the books in a library follow a normal distribution. If the mean number of pages is 180 and the standard

laiz [17]

Answer:

option B.

About 16% of the books have fewer than 150 pages

Step-by-step explanation:

Since we are dealing with a normal distribution

68.27% of the values will fall in the range with the standard deviation

(180-30 , 180+30) = (150, 210)

Approximately 15.86% of the values will be higher than 210

and the rest 15.86% will be lower than 150

So the correct answer is option B.

About 16% of the books have fewer than 150 pages
