Answer: 7 clients
Step-by-step explanation:
Of the last 10 clients that cut their hair at the salon, 5 had blond hair.
That is a proportion of:
= 5 / 10
= 1/2
Assuming this same proportion applies to the next clients Sue gets, the expected number of blonde people will be:
= Number of clients * 1/2
= 14 * 1/2
= 7 clients
F(x) = 3 x 2 − 3 x − 6 The domain of a the function f(x) is { -10, -1, 1, 5 }. What is the range of the relation?
Answer:
{324, 0, -6, 54}
Step-by-step explanation:
Given that F(x) = 3x² − 3 x − 6 If the domain of a the function f(x) is { -10, -1, 1, 5 }.
To get the range, we will find f(x) for all the domains
at x = -10
f(-10) = 3(-10)²-3(-10) - 6
f(-10) = 3(100)-3(-10) - 6
f(-10) = 300+30-6
f(-10) = 330-6
f(-10) = 324
at x = -1
f(-1) = 3(-1)²-3(-1) - 6
f(-1) = 3(1)-3(-1) - 6
f(-1) = 3+3-6
f(-1) = 6-6
f(-1) = 0
at x = 1
f(1) = 3(1)²-3(1) - 6
f(1) = 3(1)-3(1) - 6
f(1) = 3-3-6
f(1) = 0-6
f(1) = -6
at x = 5
f(5) = 3(5)²-3(5) - 6
f(5) = 3(25)-3(5) - 6
f(5) = 75-15-6
f(5) = 60-6
f(5) = 54
Hence the range of the relation are {324, 0, -6, 54}

I REALLY REALLY NEED HELP ON THIS I DON'T UNDERSTAND IT!!!!!!!!!!!!!!!!!
Answer:
d
Step-by-step explanation:
in order for it to be a triangle the angles have to add up to equal 180
5+75+100=180 so its not a
10+80+90=180 so its not b
20+60+100=180 so its not c
45+45+45=135 so its d because the angles dont add up to 180
50+50+80=180 so its not e
Answer:
D
Step-by-step explanation:
To be a triangle, you have to have 180 degrees. if you add up all of the sides, it should give you 180. If it doesn't, it isn't a triangle. I hope that helped! :)

Determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°
Answer:
Step-by-step explanation:
x=5
y=-5
Hence it lies in 4th quadrant.
x=r cos θ
5=r cos θ ...(1)
y=r sin θ
-5 =r sin θ ... (2)
square and add
(5)²+(-5)²=r²(sin ²θ +cos ²θ )
r²=25+25=50
r=±5√2
dividing
tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)
θ=135°,315°
so polar coordinates are (5√2,315°) and (-5√2,135°)
What is 6.9-(-5)+4.1
Answer:
16
Step-by-step explanation:
6.9+5+4.1
11+5
16
pls thanks
Answer:
16
Step-by-step explanation:
Recall that the product of a negative number and another negative number is a positive number. Thus, -(-5) = +5, and the original expression becomes
6.9 + 5 + 4.1.
Combining the mixed numbers 6.9 and 4.1, we get 11.
Combining 11 and 5 results in 16.
Which of the following is true?
|−6| < 5
|−6| < |5|
|−5| < |−6|
|−5| < −6
Answer:
Answer vary :
|-5| < |-6|
Step-by-step explanation:
honestly in my opinion that’s the answer.
‘these lines | change a negative number to a positive so if it changes -5 and -6 to positives.
wich makes |-5| < |-6| the right one.
and that’s how I came to that solution.

Solve the system by substitution.
x= -5y - 6
5x – 3y = -2
What’s is the solution?
The value of x is -1 and value of y is -1.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are
x+5y=-6...(1)
5x – 3y = -2...(2)
Multiply equation 1 with 5
5x+25y=-30..(3)
Subtract equation 2 and equation 3
5x-3y-5x-25y=-2+30
-28y=28
Divide both sides by 28
y=-1
Now plug in y value in equation 1
x=5-6
x=-1
Hence, the value of x is -1 and value of y is -1.

Meaghan and Lily are dividing 43.61 by 7. Meaghan says that the first digit of the quotient is in the ones place. Lily says it is in the tens place. Who is right? How do you know?
Answer: Meaghan is right.
Step-by-step explanation:
For a number like:
123.45
the tens place would be the "2" (second number at the left of the decimal point)
The ones place would be the "3" (first number at the left of the decimal point)
Let's suppose that Lily is correct.
Then the quotient of:
43.61/7
Will be a number with two digits in the left of the decimal point.
The smallest number that meets this condition, is the number 10.
Then let's see:
7*10 = 70
then:
70/7 = 10
and:
43.61 < 70
(70 is larger than 43.61)
then:
43.61/7 < 70/7 = 10
Then:
(43.61/7) < 10
This means that our quotient is smaller than 10, then the first digit of the quotient can not be on the tens place.
Then Meaghan is the correct one.
We also could perform the quotient to find:
43.61/7 = 6.23
So yes, Meaghan is correct.
Find X (the angle are X, 81, and 84)
Answer:
15
Step-by-step explanation:
