Answer:
Step-by-step explanation:
The missing parameters are:
--- population
--- population mean
-- population standard deviation
Required
First, calculate the sample standard deviation
Next, calculate the sample mean
So:
So, we have:
Calculate the z score
So, we have:
From the z table
So:
Answer:
w = 10 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = base × height
here base = 6 and height = 8, thus
A = 0.5 × 6 × 8 = 3 × 8 = 24 cm²
The area of the rectangle = 5 × 24 = 120 cm²
area of rectangle = lw ( l is length, w is width )
Here l = 12, thus
120 = 12w ( divide both sides by 12 )
w = 10 cm
Answer: 170
Steps:
Range- the difference between the greatest and smallest value of a data set.
546 - 376 = 170
Y=6x-27...........(1)
y=4x-17...........(2)
By comparison
6x-27=4x-17
=> 2x=10 => x=5
Substitute x=5 into (1)
y=6(5)-27=3
Check:
y=4(5)-17=3 as well.
