Answer:
74.483
Step-by-step explanation:
to get the mean, or the average. you add up all the numbers and divide them by how many there are.
53.9 + 73.75 + 95.8 = 223.45 ÷ 3 = 74.483
find the mean absolute deviation of the set of data

Answer: MAD= 2.8
Step-by-step explanation: start by finding the mean of the data set. find the sum of the data values, and divide the sum by the number of data values.
Please help me I am so bad at math
(f ◦ g)(x) is the composition of f(x) with g(x), equivalently
(f ◦ g)(x) = f(g(x))
To get f(g(x)), replace every instance of x in the definition of f(x) with g(x):
f(x) = -x + 7 ⇒ f(g(x)) = f(√(x - 3)) = -√(x - 3) + 7

if x+y= -10 and x-y=2 what is the value of x
Answer:
X+Y=10, X-Y=2, what is X, Y?
Answer: x=6 and y=4
Explanation:
Given:
x+y=10 ⟶(i)
x−y=2 ⟶(ii)
From equation (ii) ,
x=2+y
Put value of x in equation (i) ,
2+y+y=10
2+2y=10
2(1+y)=10
1+y=102
1+y=5
y=5−1
y=4
Put value of y in equation (ii) ,
x−4=2
x=2+4
x=6
x + y = 10 → Eq A
x – y = 2 → Eq B
Now we will take out the expression of x from Eq A.
x + y = 10 Eq A
x = 10 – y → Expression of x
Now put the expression of x in Eq B.
x – y = 2
( 10 – y ) – y = 2
10 – 2y = 2
10 – 2 = 2y
8 = 2y
y = 8 / 2
y = 4
Now put the value of y in expression of x.
x = 10 – y
x = 10 – 4
x = 6
So, x = 6 and y = 4.
Thank you.
Hope it helps and you like it
x + y = - 10 (equation 1)
x - y = 2 (equation 2)
using equation 2 we get x = 2 + y
putting the value of x in equation 1 we get :
(2 + y) + y = - 10
2 y = -10-2
2 y = -12
y = -6
put the value of y in any equation
to get the value of x
x - y = 2
x - (-6) = 2
x + 6 = 2
x = -4

Answer:
x = 25,
Step-by-step explanation:
(4x + 3) + (2x + 27) = 180 (Told they were a linear pair) (supplementary)
6x +30 = 180 (Combine like terms)
6x = 150 (Subtract 30 from both sides)
x = 25 (Divide both sides by 6)
m<RQS = 4(25) + 3
= 103 degrees
m<TQS = 2(25) + 27
= 77 degrees

Find a fraction that is more than 0 and less than 1/1000
Answer:
Any of these are correct:
1/1001, 1/1002, 1/1003
1/2000, 1/2358
1/10000
2/3000= 1/1500
3/4000
so many!
Step-by-step explanation:
Anything that is positive and not negative will be bigger than zero.
Anything with a 1 on top (numerator) and LARGER than 1000 on the bottom (denominator) will be less than 1/1000.
OR you can change 1/1000 by multiplying 2/2 or 3/3 or 4/4 or 5/5 etc. Then lower the top number only. Example:
1/1000 × 5/5 = 5/5000
(multiply straight across: top×top and bottom×bottom)
Then shrink the top:

Which choice is equivalent to the expression below?
√-12
A. 2√3i
B. 2i√3
C. 12i
D. -2√3
E. -12i
Answer:
Step-by-step explanation:
Remark
√-12
The square root of -12 must have an i in it somewhere. If it does not, then the minus sign stays under the root sign. If you take the root of -1 you get i, and that is outside √ sign.
Solution
A is incorrect. i is on the outside of the root sign.
B is the answer.
C does not seem to take the square root of anything except -1 so it is incorrect.
D Has no i anywhere and the -1 is incorrectly placed. D is wrong
E is just wrong. The minus should disappear once the square root of -1 is taken. 12 has a root that has not been declared.

thankyou ~
Answer:
x = 2 or x = 3
Step-by-step explanation:
x² - 5x + 6 = 0
x² - (3 + 2)x + 6 = 0
x² - 3x - 2x + 6 = 0
x(x-3) - 2(x - 3) = 0
(x - 3)(x -2) = 0
Either,
x - 3 = 0
x = 3
Or,
x - 2 = 0
x = 2

Based on the definition of the formula unit, the only one that is an example of this concept is NaCl.
What is a formula unit?In chemistry, this concept refers to the representation of an ionic compound. This formula differs from others because it displays the lowest possible ratio in which the ions have the same charges and therefore the compound is neutral.
What is one example of this formula?A classical example of this concept is NaCl because this includes a cation (positively charged) and an anion (negatively charged). Moreover, in this formula, the compound shows the lowest possible ratio between the two elements.

If the factored form of a quadratic is 4(x - 3)(2x + 5) = 0, what are the roots? A. 2,-3, and 5/2 B. 3 and -5/2 C. -3 and 2/5 D. - 3 and 5/2
Answer:
B. 3 and -5/2Step-by-step explanation:
The roots of a quadratic equation make the value of the equation equal to 0Here, the equation is :
4(x - 3)(2x + 5) = 0So, whatever values of x makes the equation 0 are the roots.
Hence,
x - 3 = 02x + 5 = 01st x value
x - 3 = 0x = 32nd x value
2x + 5 = 02x = -5x = -5/2The roots are 3 and -5/2.

The correct matches are:
32 corresponds to log₂(x) = 5
3 corresponds to log₃(x) = 1
1,000 corresponds to log₁₀ (x) = 3
625 corresponds to log₅(x) = 4
16 corresponds to log₄(x) = 2
What is Logarithm?A logarithm is a mathematical function that represents the exponent to which a specific base must be raised to obtain a given number. In other words, it is the inverse operation of exponentiation.
The logarithm of a number x to a given base b is denoted as log_b(x), where b is the base and x is the number. It represents the power to which the base must be raised to obtain the value x.
The logarithmic equations and their corresponding x-values are as follows:
log₂(x) = 5 → x = 32
log₃(x) = 1 → x = 3
log₁₀(x) = 3 → x = 1,000
log₅(x) = 4 → x = 625
log₄(x) = 2 → x = 16
So, the correct matches are:
32 corresponds to log₂(x) = 5
3 corresponds to log₃(x) = 1
1,000 corresponds to log₁₀ (x) = 3
625 corresponds to log₅(x) = 4
16 corresponds to log₄(x) = 2

Rebecca is saving money to purchase a laptop which cost $1,099.51 she has already saved $354.20 and plans to continue saving $50.60 per week which inequality could be used to find W the number of weeks of Rebecca must save in order to purchase a laptop
Answer:
745.31+50.60w=1,099.51
W=7
Step-by-step explanation:
1st subtract 1099.51 from 354.20
2nd use your answer which is 745.31 and add that with how much she plans on saving for how ever long
3d to find out how many weeks which is 50.60*w you need to first minus 745.31 from both sides
4th so 745.31- 745.31 and 1099.51-745.31 =354.2 or .20
5th divide 354.2 by 50.60 =7
So overall w= 7
