Hope this helps!!

Answer 2

9514 1404 393

Answer:

  False

Step-by-step explanation:

A relation is a function if and only if there is exactly one output for each input. Any relation map with two or more arrows coming from any input is NOT a function.

Here, the input "2" has two outputs, 4 and 5, so this map does not show a functional relationship.

The circus admits children for $2 each and adults for $5 each. How many of each ticket were sold if 160 total tickets were sold for $476?

Answers

Basically you solve this by elimination or substitution
So you first make an equation where
c represents numbers of children tickets and ‘a’ represents adult tickets
a+c= 160
2a+ 5c=476


Multiply first equation by -2 to cancel out the a after addition
-2a-2c =-320
When you add the above equation with 2a +5c=476 you get 3c=156 which means that c=52 so the number of children tickets sold = 52
Now you substitute this answer to any of the equations and work out the value of a
a+52=160
a= 108

Which of the following is equivalent to 3^4?
1. 12
2. 81
3. 7
4. 64

Answers

i think the answer is 12 because 3 times 4 is 12

Answer:

81, Option 2.

Step-by-step explanation:

[tex]3^{4}[/tex] means 3 x 3 x 3 x 3, that is 3 multiplied 4 times with itself.

Here's how to do it:-

3 x 3 = 9

9 x 3 = 27

27 x 3 = 81

So, [tex]3^{4}[/tex] would be 81, Option 2.

NEED HELP PLEASE ASAP! please don’t waste my time i need this grade.

Answers

Hmm I think the answer is 95%
1 standard deviation is 13
To find out the range of scores that fit 1 standard deviation from the mean, you would have to take away and add 13 from the mean (133) this gives a range of 120-146 which isn’t right because you’re looking for 107-159.
Next, look for 2 standard deviations from the mean which is just 13 x 2=26.
To find the range of scores that are 2 standard deviations from the mean take away and add 26 to the mean (133) which gives a range of 107-159. This is the correct answer.
2 standard deviations represents 95% of the data. That’s why I think the answer is 95%.

HELP PLEASEEEEE

Answers

Answer:

1 (100block)

5 (10block)

3 (1block)

Step-by-step explanation:

221-68=153

1x100=100

5x10=50

3x1=3

The amount that x = 53 needs to be to balance the scale.

What is an equation?

The term "equation" refers to a pair of algebraic expressions with the same value and the sign "=" in between.

We have an equation,

221 = x + 68

x = 221 - 68

x = 153

In 153,

1 is in place of hundred 100, 5 is in the place of 10 so, 50.

Therefore, x = 53 is the amount that needs to be to balance the scale.

The common difference is the coefficient of  n.  Another way to see this is to compute the second term, f(2) = 8 - 3(2) = 8 - 6 = 2.  The second term is 3 less than the first.  The common difference is -3.
