PSYCHO15rus [73]

Answer:

e. 5.0329 g/mL

Step-by-step explanation:

Density is defined as mass divided by volume of an object. The volume displaced is:

v=29.90mL-25.20mL\\=4.7mL

#Density is then calculated as:

d=\frac{23.6546g}{4.7mL}\\\\=5.0329g/mL

#Correct significant figures should correspond to the highest given in the question.

Hence the density of the metal is 5.0329g/mL

The medium is 3.


2. for the mean you add all the numbers up and then divide based on how many numbers there are.

0 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 3 + 3 + 5 + 5 + 6 + 6 + 7 + 11 / 16

64/16

4

the average or mean is 4 which tells us that the average number of kids per houshold is 4. and none of the housholds have 4 children. we know this because of the data in the line plot.

the typical houshold size is either 3 or 4. the medium is 3 and the average or mean is 4.

10 points please

Find the average rate of change for f(x) = x2 + 9x + 18 from x = 10 to x = 20.
Montano1993 [528]

Answer:

The average rate of change is 39

Step-by-step explanation:

First, plug x=10 and x=20 into the formula:  

10^2+90+18

190+18

208

20^2+180+18

400+198

598

598-208=390

390/10 = 39

The average rate of change is 39
