A hair stylist knows that 87% of her customers get a haircut and 40% get their hair colored on a regular basis. Of the customers who get their hair cut, 24% also get their hair colored. What is the probability that a randomly selected customer gets their hair cut and colored?
Answer:
0.35
Step-by-step explanation:
The probability that a customer gets a hair cut and also gets a hair colored is 0.2088
What is probability?Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.
Given here: The probability of customers getting a haircut is 87% and the probability that the customers that have a haircut also get their hair colored are 24%
Thus the conditional probability that a customer who has a hair cut also gets his hair colored is
P( haircut/hair colored )= 87%×24%
=0.87×0.24
=0.2088
Hence, The probability that a customer gets a hair cut and also gets a hair colored is 0.2088

You want to buy a shirt that costs $14. Identify an inequality that represents the amount of money, x (in dollars), you will have left if you buy the shirt
Complete question :
You can spend up to $35 on a shopping trip.
a. You want to buy a shirt that costs $14. Write and solve an inequality that represents the amount of money you will have left if you buy the shirt.
b. You notice that the shirt is on sale for %30 off. How does this change the inequality?
c. Do you have enough money to buy the shirt that is on sale and a pair of pants that cost $23? Explain.
Answer:
x ≤ 21
x ≤ 25.2
Yes
Step-by-step explanation:
Cost of shirt = $14
Total Amount to spend ≤ $35
After shirt purchase :
Let amount left = x
x + 14 ≤ 35
x ≤ 35 - 14
x ≤ $21
B.) discount on shirt sale = 30%
(100% - 30%) of $14 = 0.7 * $14 = $9.8
x ≤ 35 - 9.8
x ≤ 25.2
C.)
Cost of Jean = 23
25.2 > 23

i dont know what you are asking, make your question more readable and clear
Step-by-step explanation:
Express z 1 = 17 [ cos ( π ) + i sin ( π ) ] z 1 =17[cos(π)+isin(π)]z, start subscript, 1, end subscript, equals, 17, open bracket, cosine, left parenthesis, pi, right parenthesis, plus, i, sine, left parenthesis, pi, right parenthesis, close bracket in rectangular form. Express your answer in exact terms.
Answer:
z1 = -17 + 0i
Step-by-step explanation:
Given the complex number z1 =17[cos(π)+isin(π)], we are to express it in rectangular form as shown;
Since cos(π) = -1 and sin(π) = 0, the equation becomes;
z1 =17[cos(π)+isin(π)]
z1 =17[(-1)+i(0)]
z1 = 17(-1 + 0i)
z1 = -17 + 0i
Hence the complex number in rectangular form is expressed as z1 = -17 + 0i

Klara picks a number. She rounds to the nearest hundred. She rounds tot the nearest thousand. She rounds the number to the nearest ten thousand. All three times, the result is the same. Which choice could be klara's number?
Answer with step-by-step explanation:
The question does not seem complete, but I'll try to make some explanations.
When you want to round a number, there are some rules.
1. If the number you are rounding is followed by 5, 6, 7, 8, 9, then round the number up, that is add 1 to it.
2. If the number you are rounding is followed by 0, 1, 2, 3, 4, then round the number down, that is add 0.
Now if given a number and you are asked to round to the nearest 100, 1 000, 10 000 and so on, then for nearest 100, count 2 numbers from the back. Whatever number you stop at, that is the number you are to round. For 1000 count 3, for 10 000 count 4 and so on.
Since Kiara is having the same value after rounding, it means she picked a number that has zeros after the 10 000th value
Let's assume she picked: 70 000
Rounding that number to nearest 100, 1000 and 10000 gives the same number which is
70 000.

Answer:
y=5/2x-16
Step-by-step explanation:
First, we want to find the slope of the original line.
m= -4+8/-1-9
m= 4/-10
m= -2/5
Because we want the perpendicular bisector, we will need the slope to be the opposite reciprocal. Therefore, our slope is
m=5/2
Now, we want to find the midpoint of the line.
9-1/2
8/2=4
-8-4/2
-12/2= -6
So, the midpoint is (4,-6)
Using the information we have, we now can find b.
-6=5/2(4)+b
-6=10+b
-16=b
That gives us our equation
y=5/2x-16

Can anyone show me how to solve this problem? I know that its 5 weeks. (The problem is “Ahmed is saving his money to buy a Ipad that costs $319.50. Right now he has $21.95, and can save $63.00 each week. How many weeks will it take for Ahmed to have enough money to buy the Ipad)
Answer:
5 weeks
Step-by-step explanation:
Substract 319.5 (the amount he has to save) to the amount he has already saved, which is 21.95. Now the constant amount of change is 63 dollars each week so divided it by that. So the equation should be (319.5-21.95) and divide all that by 63 to get 4.72 or rounded to the nearest number, is 5.
The measurement of the “ridge” of your new house on blueprints is 24 inches. If the scale is 1/4 = 1ft how long is the wall in real life
Answer:
In real the wall will be: 96 ft
Step-by-step explanation:
Given that the scale is
1/4 = 1ftIt means 1 inch will represent 4 ft.
so
1 inch = 4ft
Given that the measurement of the “ridge” of your new house on blueprints is 24 inches.
Thus,
24 inches = 24 × 4ft ∵ 1 inch = 4ft
= 96 ft
Therefore, in real the wall will be: 96 ft

Answer:
A=2.5
B=2
Step-by-step explanation:
A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.
We can compare the two sides using algebra.
4b+7=8b-1
Using simple methods, we can isolate b on a single side.
1+7=8b-4b
8=4b
b=2
From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.
2a = 2b+1
2a = 2(2)+1
2a=4+1
2a=5
a=2.5
Ellen writes 2 pages in a hour. Determine the equation that represents the function and state it graphically.
Answer:
1 page every 0.5hours, or 1 page every 30 minutes. The equation is
2x = y
Solve for the variable x.
4(x - 11) = -210
Answer: Divide both sides by the numeric factor on the left side, then solve.
Exact Form: x= −83/2
Answer: x = -41.5
Step-by-step explanation:
Distribute the 4 that is outside of the parentheses.
4 times x = 4x
4 times -11 = -44
Then to isolate the variable add 44 to both sides of the equation to cancel out -44.
-44 + 44 = 0
-210 + 44 = -166
Now your equation should 4x = -166
To find x, divide both sides of the equation by 4.
4x divded by 4 is x.
-166 divded by 4 is -41.5.
So the answer is x = -41.5.
To check the answer, plug in -41.5 to the x.
4(-41.5 - 11) = -210

Answer:
Step-by-step explanation:
If we take 1 cup of Original purple paint,
Ratio of blue and red paint = 2 : 3
Quantity of blue paint in 1 cup of the mixture = [tex]\frac{2\times (1)}{(2+3)}[/tex] = 0.4 cups
Similarly, ratio of blue and red paint in the New purple paint = 5 : 7
If we take 1 cup of New purple paint,
Amount of blue paint in 1 cup = [tex]\frac{5\times 1}{(5+7)}[/tex] = 0.42 cups
Therefore, shade of both the mixtures will not be same.
Since, blue color is more in quantity in New purple paint, it will be more blue than Original purple paint.
