Answer:
31.5%
Step-by-step explanation:
If 70% of customers get an oil change, and 45% of those get their tires rotated, then this is a method I use to find the answers to these types of problems.
70% of customers, 45% of 70
One method that will help you so much is this simple equation: x% of y= y% of x. For example, if you need to find 3% of 50, the same value is given for 50% of 3, which would be 1.5. Using our given digits,45% of 70 is the same as 70% of 45.
A method that can add on to this is one I've come up with myself. If you divide your original number by 100, then multiply it by your given percentage, it will give you your wanted value, so if you plug in your values, 70/100, multiplied by 45, will equal 31.5%.
Answer: The number of containers of cookies machine fill in 8 hours can be, 1920
Step-by-step explanation: You would need to find how many containers of cookies they make in a hour which is 240 so then 240 times 8 is 1,920
You have a lot of different questions here, I can help with the first part.
The range is the highest minus the lowest.
26 - 10 = 16
The mean is the result when you add them all up and divide by 10.
170 / 10 = 17
The median is the middle number in order.
The middle is at 15.
The mode is the number that shows up the most.
14 appears twice, every other number appears only once.
If the service is open for 9 hours and for each hour 3 dogs can be groomed then the maximum amount of dogs that it could groom is:
9 x 3 = 27.
Y = 1/3x ? 6....slope here is 1/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will have a slope of -3 (see how I flipped 1/3 and changed the sign)
y = mx + b
slope(m) = -3
(-9,12)...x = -9 and y = 12
now we sub and find b, the y int
12 = -3(-9) + b
12 = 27 + b
12 - 27 = b
-15 = b
so ur perpendicular equation is : y = -3x - 15
