Mean of the given distribution = 2
Step-by-step explanation:
Explanation:-
Given data from histogram
1 , 4, 5 ,4 ,2, 1, 1 , 1, 1,0
Mean of given data
= ∑x / n
Given n = 10
[tex]Mean = \frac{1+4+5+4+2+1+1+1+1+0}{10} = \frac{20}{10} =2[/tex]

Consider this function.
(r) = -3r + 3
Which graph represents the inverse of function ?
9514 1404 393
Answer:
C. graph Y
Step-by-step explanation:
Starting with f(r) = -3r +3, the inverse function can be found from ...
r = f(y)
r = -3y +3
r -3 = -3y
(r -3)/-3 = y
y = -1/3r +1
The inverse function will have a slightly negative slope and a y-intercept of 1. This matches graph Y.
Deborah spent $70 on food and clothes she spent $26 more on clothes then on food Brighton solve a system of equations to find how much Debra spent on each
Answer:
Step-by-step explanation:
You know the total will be $70.
She bought food, let's call that "F"
She spent $26 more on clothes than food. So her clothes purchase is "F+26".
So let's set-up the equation this way:
food + clothing = Total Spent
F + F + 26 = 70
2F + 26 = 70 (subtract 26 from both sides of the = sign)
2F = 44 (Divide both sides so you find out how much was spent on "F" or food.)
F = 22 (But the question doesn't stop there.)
Deborah spent $22 on food. (Remember, she spent $26 more on clothes, so we have to use our "clothes" equation? ) Deborah spent $48 on clothes. She spent a total of $70 on her purchases.

Solve the equation.
S- (- 20) = 19
Answer:
s = -1
Explanation:
s − (−20) = 19
[ Simplify both sides of the equation ]
s + 20 = 19
[ Subtract 20 from both sides ]
s + 20 − 20 = 19 − 20
s = −1

Santiago starts a savings account with $20. Each month he deposits $15 more into the account. Santiago wants to save a least $80. Write an inequality that represents this situation.
Answer:
$20 + $15m ≥ $80
Step-by-step explanation:
He starts off with $20.
He adds $15 each month, so $15m.
He wants to save at least $80, which means greater than or equal to $80. So, you use this symbol: ≥
Put it all together.
$20 + $15m ≥ $80
Hope that helps.
How do you inverse 3x-4y=6
Answer:
To find the inverse you switch x and y
Step-by-step explanation:
3y-4x=6
So 3y = 4x+6
and Y = 4/3x + 2
Answer:
y=(6-3x)/-4
Step-by-step explanation:
to get the inverse we make y the subject of the equation
3x-4y=6
-4y=6-3x
y=(6-3x)/-4
Solve using substitution.
- x - y = -1
X = 2
Answer:

y = -1
Step-by-step explanation:
-(2) - y = -1
add 2
-y = 1
divide by -1
y = -1

4 x 10^3 times what number is equal to 16 x 10^3
The number which is 4 x 10^3 times equal to the number 16 x 10^3 after is number 4.
What is the product?Product is the resultant number which is obtained by multiplying a number with another. Let a number a is multiplied by number b. Then the Product of these two number will be,
[tex]P=a\times b[/tex]
Here, (a, b) are the real numbers.
The 4 x 10^3 times a number is equal to the number 16 x 10^3 Let suppose this number is n. Thus,
[tex]4\times10^{3}\times n=16\times10^{3}[/tex]
Divide both side of the equation with 4 x 10^3 as,
[tex]n=\dfrac{16\times10^{3}}{4\times10^{3}}\\n=\dfrac{16}{4}\\n=4[/tex]
Hence, the number which is 4 x 10^3 times equal to the number 16 x 10^3 after is number 4.

Answer:237 . 12
Step-by-step explanation:
pleas give me a BRAINLY pleas
Answer:
y = 4[tex](3)^{x}[/tex]
Step-by-step explanation:
For an exponential function in the form
y = a [tex]b^{x}[/tex]
Use the given points to find the values of a and b
Using (1, 12), then
12 = ab → (1)
Using (2, 36), then
36 = ab² → (2)
Divide (2) by (1)
[tex]\frac{36}{12}[/tex] = [tex]\frac{ab^2}{ab}[/tex] , then
3 = b
Substitute b = 3 into (1) for value of a
12 = 3a ( divide both sides by 3 )
4 = a
Thus
y = 4[tex](3)^{x}[/tex] ← is the exponential function
