Answer:
<em>Dale put 6.21 grams of salt into the soup in all</em>
Step-by-step explanation:
<u>Arithmetic</u>
There are situations where different mathematic operations must be done in order to find the required results. Four operations are known as basics in arithmetic: addition, subtraction, multiplication, and division.
The question describes how Dale added 5.0 grams of salt into a pot of soup and then he added 0.31 grams of salt more. This means the total amount of salt added by Dale into the soup is the sum of both quantities:
Total salt added = 5.9 grams + 0.31 grams = 6.21 grams.
Dale put 6.21 grams of salt into the soup in all
Answer:
7
Step-by-step explanation:
When you match the form
... ax² + bx + c = 0
to the equation
... 3x² + 5x + 7 = 0
it is reasonable to conclude that ...
... a = 3, b = 5, c = 7.
_____
The question presumes you are familiar with the form
... ax² +bx +c = 0
which is often used as the representation of a general quadratic equation. This lets us use a, b, and c instead of specific numbers, to talk about ways of factoring, graphing, or solving equations like this.
Answer:
Range values are:
{-11, 1, 4, 10, 25}
Step-by-step explanation:
Domain values are the possible x values that can be entered into the function, or the inputs. Range values are the y values, or the outputs. By inserting every value in the set into the function, we get the outputs (y values)
-15 + 4 = -11
-3+4 = 1
0 + 4 = 4
6 + 4 = 10
21 + 4 = 25
Remember to put them in order.
Slope Formula:

I am going to show you how to do this on problem 6, and you will do the rest of the problems.
Here are the steps to solving problem 6
Step 1) Substitute the coordinates into the slope formula

Step 2) Now Lets simplify the denominator, so we don't have two Subtractions symbols.

Step 3) Simplify

Step 4) We can still simplify more

Hope This Helps ... Good Luck
[The reason I didn't do all of them is because you need to know how to do them. Trust me later on knowing these is going to be very handy.]
Let
n = number of data
s = standard deviation (sample)
S = standard deviation (population)
The working equations is

To find

, : (1 - 0.90)/2 = 0.05
To find

, : 1 - 0.05 = 0.95
Degrees of freedom = n-1 = 24 - 1 = 23
This is shown in the figure attached. Since there is no row for df=23, we interpolate. Thus,
Substitute all values,

Thus the answer is,
