Which ordered pairs cause this relation NOT to be a function? Why?
{(0,0.5), (0.5, 1). (3.1), (1,6). (3. 2)}
Answers
Answer:
(3,1) and (3,2)
Step-by-step explanation:
We are given that a relation
{(0,0.5),(0.5,1),(3,1),(1,6),(3,2)}
We have to find that ordered pair which causes this relation not to be a function.
We know that
Function: It is a mapping between two non- empty set A and B.
Every element of set A has unique image in set B.
One element of set A can not have two or more images in set B.
Two or more elements of set A have same images in set B.
In given relation images of 3 are 1 and 2 which is not possible if a relation is function because one element can not have two or more images.
The ordered pair (3,2) and (3,1) cause this relation not to be a function because image of 3 are 1 and 2 which is not possible .
Answer: (3,1) and (3,2)

Nico has $11.50 deducted from his weekly paycheck for health care. If his employer pays 90% of the premium, how much is his annual premium ?
A) $5980
B) $2990
C) $665
D) $115
Answers
Answer:
Nico's annual premium is A) $5980.
Nico has $11.50 deducted from his weekly paycheck for health care.
So,
Nico's annual deduction are:
Since there are 52 weeks in a year.
So,
11.50*52=$598
His employer pays 90% of the premium, means Nico pays 10%.
And $598 is 10% of total annual premium.
Let annual premium is x.
10%of x =$598
10/100*x=$598
x=$598*10
x=$5980
Hence, Nico's annual premium is $5980

The most typical approach to display data using a chart is a graph that shows the relationship between two additional variables.
Diagrams created by hand or on a computer are also acceptable.
Move 2 units to the right after starting at the origin before going 3 units up.
The coordinates for the points 2, 3, should be shown on the coordinate plane. Clearly state your points.
The pink dot with the letter P thus stands for 2.3.
Before creating a line chart, you need first generate a number line for each value in your data collection.
Put an X (or dot) over each value of the data on the number line after that. For each instance when a value appears in a record, place an X over the corresponding number.
x = 0.83
y = 0.79
z = 0.83
xa = 0.85
ya = 0.85
za = 0.85

Answer:
P = n * t * (S - C) - H - (n * W)
n = (P + H) / (tS - tC - W)
Step-by-step explanation:
n = number of employees to be hired
P = profit
W = employee wages per day
t = average toys made by each employee per day
S = selling price of each product
C = cost price of each product
H = daily overhead costs
Equation for profit is selling price - cost price for all the toys made for that day
which is no. of employees * t * (S - C)
we will also cut daily overhead costs from profit
and also daily wages for all employees
P = n * t * (S - C) - H - (n * W)
Now we have to find n based on other factors / variables
P = ntS - ntC - H - nW
P = n (tS - tC - W) - H
P + H = n (tS - tC - W)
n = (P + H) / (tS - tC - W)

what is 6 to the 2 power -4 divided by 2 simplified'
Answers
Answer:
36 and 34
Step-by-step explanation:
Not sure what youre asking...but 6 power 2 is 36 and -4 divided by 2 is 34.
If you are asked to take 6 and multiply it by 2, you are really doubling 6. In other words, 6 times 2 is like saying you have two 6's. Together, two 6's make 12. So, 6*2 = 12.
When you take 6 and square it (raise it to the power of 2), you are taking 6 and multiplying it by itself. So, 62= 6*6 = 36.
Using the same logic, you can see how this works for other powers.
61 = 6
62 = 6*6
63 = 6*6*6
64 = 6*6*6*6
etc...
Hope this helps
I thought that I would help explain the laws of exponents a little more for you. It might help you in your future studies.
Using an exponent just saves you the time of writing out lots of multiples. In your example, 6^2=6×6
You can also solve problems involving exponents on a graphing calculator by entering the base, followed by the caret key ^, enter the power, and then press enter. In your case, you would enter it into your calculator like this, 6^2.
For future reference, just remember
The exponent tells you how many times you need to multiply the number
And if you see a negative exponent, it just means to divide 1 by the number, because the opposite of multiplying is dividing (for example, if you had 6^(-2), it would look like this, 6^(-2)= 1 ÷ 6 ÷ 6=0.027778 or enter it into your graphing calculator like so, 6^+/-2 You may have a +/- button or just a – button. Remember, this is not the subtract button!

Answers
Answer:
Well assuming its playing cards
There are 54 playing cards including jokers.
There are only 2 red 6 cards.
The hearts and the diamonds.
Now so techincially its a 2/54 chance
So 2/54 chance of drawing a red card
Answer:
2/52
Step-by-step explanation:
52 cards in a deck as jokers are not used in professional card places red = 1/2 of 52 = 26/52 drawing red 6 = 1/2 of 4/4 = 2/4 26/52 / 2/52 = 13 which proves 13 cards in each red and 2/52 red 6's in a full deck

Trey runs 3 miles in 25 minutes. At the same rate, how many miles would he run in 20 minutes?

Answer:
Step-by-step explanation:
Set up a proportion.
3/25 = x / 20 Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.
Cross multiply
3 * 20 = 25 * x Combine
60 = 25x Divide by 25
60/25 = x
x = 2.4 miles in 20 minutes.
Answer:
In 20 minutes, Trey would run 2.4 miles.
Step-by-step explanation:
20x = 25
x = 4/5
This means we multiply the number by 0.8
3 * 0.8 =
3/25 = 2.4/20
