How would I find the mean, median and mode ?

snow_tiger [21]

Answer:

Mode is the number that occurs most often in the data set. lets say i have the numbers(6,9,2,0,3,2,1,2) it would be two because there are more two's than any other number in the data set.

Mean is found by adding all of the numbers together in the data set. you simply add your numbers together.

Median is the number that is found halfway in the data set. for example if i had the numbers (6,9,2,5,0,2,1) the median would be 5.

I hope this helps you!

A pet store has 150 goldfish and betta fish altogether. The ratio of goldfish to betta fish is 2:3. How many goldfish does the p

Kipish [7]

The number of goldfish in the pet store is equal to 60 fishes.

Let the goldfish be G.

Let the betta fish be B.

Given the following data:

Total number of fishes = 150 fishes.

Ratio of G to B = 2:3

Total ratio= 2 + 3 = 5

To calculate the number of goldfish that the pet store have:

<h3>What is ratio?</h3>

Ratio can be defined as an expression that is used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

Mathematically, the number of goldfish in the pet store is given by this expression:

$G = \frac{2}{5} \times 150\\\\G=0.4 \times 150$

G = 60 fishes.

Factor 75t2 + 12. 3(5t + 2)2 3(25+2 +4) 3(251-4)

frosja888 [35]

Answer:

$75t^2+12=3(25t^2+4)$

Option C)

Step-by-step explanation:

Here we are given with the expression $75t^2+12$

The GCF of $75t^2$ and 12 is 3

Hence we take 3 as GCF and bring it in front of the bracket.

$3(25t^2+4)$

It can not be factorise furthure as there is no GCF of 25 and also there is no rule for sum of squares so that we may apply it on this. Hence the answer would be

$3(25t^2+4)$

Option C)

The graph of a function f(x) passes through the following points:

Alex

The function is f(x) = -2x² + 2 if the function f(x) passes through the following points:(0,2), (1, 0), (-1,0)

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

The graph of a function f(x) passes through the following points: (0,2), (1, 0), (-1,0)

Let

f(x) = ax² + bx + c

Plug x = 0, and y = 2

c = 2 ...(1)

Plug x = 1 and y = 0

a + b + c = 0 ..(2)

Plug x = -1 and y = 0

a - b + c = 0 ...(3)

After solving (1), (2), and (3)

a = -2

b = 0

c = 2

f(x) = -2x² + 2

Thus, the function is f(x) = -2x² + 2 if the function f(x) passes through the following points:(0,2), (1, 0), (-1,0)
