Simplify the expression:
–7c2–c2+–5c2–2c2+8c2–9c2

Answers

Answer:

the answer is why is math so hard

Step-by-step explanation:

Duh

i would start by grouping them into sections because they’re all like terms.
(-7c2-c2) = -8c2
(-5c2-2c2)= -7c2
(8c2-9c2) =-c2
then add them all together.
-8c2-7c2-c2
since they’re all negative you can add them together but don’t forget the negative.
8+7=15
15+1 = 16
add the negative back in to get -16c2

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.

Can you please explain this to me and answer

Answers

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°

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)

Heather deposits $7000 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in the first 3 years?

Answers

Answer:

year after 3 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $7000.00.

r is the interest rate, 2% per year, or in decimal form, 2/100=0.02.

t is the time involved, 3....year(s) time periods.

So, t is 3....year time periods.

To find the simple interest, we multiply 7000 × 0.02 × 3 to get that:

The interest is: $420.00

Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),

or 7000.00 + 420.00 = 7420.00. For example:

If you borrowed the $7000.00, you would now owe $7420.00

If you loaned someone $7000.00, you would now be due $7420.00

If owned something, like a $7000.00 bond, it would be worth $7420.00 now.

Answers

Answer:

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

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
