The school did reach the goal because if you add the games, concessions and donations you get $1232 and if you subtract 28 from it you get $1204 and if you subtract 75 from that you get $1129.
yes, they did reach their goal.

Start by adding 650, 530, and 52 because those are all the money made and received (the income). Then there are the expenses that you have to subtract due to the fact that they're losing money. So from adding all the income you get 1232 and then when you subtract your expenses you get 1129 which is a 29 dollar difference. (i hope this helped :D)

Answers

Answer: y=0.63x+12.5

sum of x = 260

sum of y = 288

mean x = 26

mean y = 28.8

sum of squares= 3000

sum of products= 1876

find the line of best fit or line of regression

regression equation = y = bx + a

b= 1876/3000 = 0.62533

a= 28.8 - (0.63*26) = 12.54133

then round and plug a and b into the equation

y=0.63x+12.5

you decide where to put the line by where the average or mean of the points are. there are clusters in the points which makes it easier to place the line of best fit. the outliers are the point scattered away from the line of best fit and the clusters are groups of point very closely put together.

Answers

Answer:

20

Step-by-step explanation:

This is the information we know :

A. a = 4

B. b = 15

C. c = 16

a + c

The a and c represent variables that must be substituted by their value, since we know their initial value, we substitute :

a + c when a = 4 and c = 16

4 + 16

20

The answer is 20 because a=4 and c=16 then 4+16=20

You ask 100 randomly chosen dog owners in your town how many dogs they own. The results are shown in the table. There are 500 dog owners in your town.

Mean: _???_ dogs per owner.

Answers

the mean is 5 since you do 500 divided by 100 which is 5

The mean number of dogs per owner in your town is 1.63 dogs

What is Mean?

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

To find the mean (average) number of dogs per owner in your town, we can use the formula:

Mean = (Sum of all values) / (Total number of values)

From the table, we can calculate the sum of all values by multiplying the number of dogs by their respective frequencies and adding them up:

(1 * 54) + (2 * 38) + (3 * 3) + (4 * 1) + (5 * 4) = 54 + 76 + 9 + 4 + 20 = 163

The total number of values (or dog owners) in your town is given as 100.

Plugging these values into the formula, we get:

Mean = 163 / 100

Mean = 1.63 (rounded to two decimal places)

Hence , the mean number of dogs per owner in your town is approximately 1.63 dogs

1)73 degrees
all the angles of a triangle add up to 180 degrees.
23+84= 107
180-107=73

2) 28 degrees
110+42= 152
180-152= 28

Explanation:

All sides in a triangle is equal to 180°
So whenever given two sides only, add them up, and subtract from 180. That will give you the missing sides length.
So 23 + 84 = 107
180 - 107 = 73
The missing side of the triangle is equal to 73°.

110 + 42 = 152
152 - 180 = 28°
The missing side of the triangle is equal to 28°.

Another example is:
100°, 40°
Front the missing side in this triangle.
100 + 40 = 140°
180 - 140 = 40°
The missing length is 40°
