Answer:
2+x^2=18 = 2+4^2=18
Step-by-step explanation:
Because when you have the ( ^2) then that means your going to multiply a number by the same number and then 4 times 4 equals 16 and you still have the +2 therefore you add that on the 16 and 16+2 equals 18.
Which set of ordered pairs represents a function?
O {(2,-2), (1,5), (-2, 2), (1, -3), (8, -1)}
O {(3,-1), (7, 1), (-6, -1), (9, 1), (2, -1)}
O {(6, 8), (5, 2), (-2,-5), (1, -3), (-2, 9)}
O {(-3, 1), (6, 3), (-3, 2), (-3,-3), (1, -1)}

Answer:
24/760/7Step-by-step explanation:
For the first dataset ...
d1 = {20, 22, 24, 28, 29, 29, 30}
The deviations from the mean of 26 are ...
d1 -mean(d1) = {-6, -4, -2, 2, 3, 3, 4}
so the total of the absolute values of these is 24. Since there are 7 numbers, the mean of the absolute deviations is ...
mad = 24/7
__
For the second dataset ...
d2 = {12, 15, 21, 30, 33, 35, 36}
The deviations from the mean of 26 are ...
d2 -mean(d2) = {-14, -11, -5, 4, 7, 9, 10}
so the total of the absolute values of these is 60. Again, there are 7 numbers, so the mean of the absolute deviations is ...
mad = 60/7

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 lower than in the first. The tax in the first city was
7.5%, and the tax in the second city was 7%. The total hotel tax paid for the two cities was $547.50. How much was the hotel charge in each city before tax?
Answer:
let the hotel charge before tax for second hotel be x
then the hotel charge before tax for first hotel = x+1500
tax of first hotel = 7.5% * (x+1500) = (7.5x+11250)/100
tax from second hotel= 7% of x = 7x/100
total tax = 547.50
7x/100 + (7.5x+11250)/100 =547.50
14.5x = 54750-11250
14.5x= 43500
x= 3000
hotel charge in first city = 4500
in second city =3000

Jean masear is a saw operator in a lumber mill. He works 40 hours a week and earns $630 per week. What is his hourly pay rate
Answer:
[tex]\boxed {\tt \$15.75 \ per \ hour}[/tex]
Step-by-step explanation:
We want to find Jean's hourly pay rate. In other words, his pay per hour.
We can find the pay rate by dividing the money he is paid by the number of hours worked.
[tex]pay \ rate =\frac{money \ paid }{hours}[/tex]
He is paid $630 for 40 hours.
[tex]money \ paid= $630 \\hours= 40\ hours[/tex]
[tex]pay \ rate = \frac{\$630}{40\ hours}[/tex]
Divide.
[tex]pay\ rate = \$15.75 / hour[/tex]
His hourly pay rate is $15.75 per hour.
Between 2000 and 2015 , the number of twin births in a certain country increased by 11%, to approximately128,760 . About how many twin births were there in 2000?
Answer:
116000
Step-by-step explanation:
The number of twins in 2000 is x
the number increases by 11% to year 2015
x(1+11/100 )=128760
x+0.11x=128760
1.11x=128760
x=128760/1.11
x=116000
Which number is a counterexample to the following statement? All numbers that are divisible by 2 are divisible by 4.
A. 0
B. 12
C. 28
D. 42
Using divisibility concepts, a counterexample to the statement is given by option the number 42, option D.
-------------
If the remainder of the division of A by B is 0, it is said that A is divisible by B.-------------
In option A, 0 is divisible by both 2(0/2 = 0) and 4(0/4 = 0), so it is not a counterexample.In option B, 12 is divisible by both 2(12/2 = 6) and 4(12/4 = 3), so it is not a counterexample.In option C, 28 is divisible both by 2(28/2 = 14) and 4(14/2 = 7), so it is not a counterexample.In option D, 42 divided by 4 is 10 with a remainder of 2, thus 42 is not divisible by 4, being a counterexample to the statement.A similar problem is given at https://brainly.com/question/24354438

1000-? i think that works
find the value of x. write your answer in simplest radical form
Answer:
[tex]x = 4 \sqrt{2} [/tex]Step-by-step explanation:
To find the value of x we can use either sine or cosine
Using cosine we have
[tex] \cos(\theta) = \frac{adjacent}{hypotenuse} [/tex]From the question
x is the hypotenuse
4 is the adjacent
We have
[tex] \cos45= \frac{4}{x} \\ x \cos45 = 4 \\ x = \frac{4}{ \cos(45) } [/tex]We have the final answer as
[tex]x = 4 \sqrt{2} [/tex]Hope this helps you
Step-by-step explanation:
Sinø=opp/hyp
Sin45=4/x. (× b.s by x)
