Answer: 80
-----------------------------------------
Explanation:
x = number of defective drives in the shipment of 20,000 total
We are told that 2 defective drives are in the shipment of 500. So the first fraction to set up is 2/500
The second fraction is x/20000 as we divide in the same order as before (number of defective over the total)
Set those two fractions together to get this proportion
2/500 = x/20000
Now cross multiply
2/500 = x/20000
2*20000 = 500*x
40000 = 500*x
500x = 40000
The last step is to divide both sides by 500 to isolate x
500x = 40000
500x/500 = 40000/500
x = 80 which is the answer we want
Note: This is an expected/estimated amount and not entirely guaranteed to be reality. It's based on the previous ratio of 2/500, assuming the same ratio is held in check.
Answer:
The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65
Step-by-step explanation:
Let x be the number of t-shirts and y be the total pay
As we can clearly see in the table that there is a linear relationship between x and y
A linear function is given as:
Here m is the gradient of the function then
Taking any two pairs of x and y
(1,68) and (2,71)
Putting in equation
Putting a pair (1,68) in the equation to find the value of b
Putting the value of b
Let p(x) be the linear function
Hence,
The linear function is: p(x) = 3x+65
Answer:
x =
Step-by-step explanation:
Given
4x + 6 = 11 ( subtract 6 from both sides )
4x = 5 ( divide both sides by 4 )
x = = 1.25

Answer:
a) Median: 9
b) Range: 5
c) Mode: 7
Step-by-step explanation:
The median is the number in the middle.
First, you put the numbers in order: 7, 7, 7, 8, 10, 11, 12, 12
The middle of this is 8 and 10, so you plus them and divide by to 2, then it gives 9, so the median is 9.
To find the range, you minus the highest number and the lowest number, 12-7=5.
Mode is the most occurring and repetitive number, in this case, 7, because it is written 3 times.
Hope this helps!!!
