The sample was 10 numbers.
4 of the numbers are less than 301.
So 4 out of 10 would be defective.
4/10 = 0.4 x 100 = 40%
He would expect 40% to be defective.
1 one is the answer
2 is the answer either
all the equations are in it's simeplest form
Answer:
99
Step-by-step explanation:
Area of trapezium = 1/2 × (sum of parallel sides × height)
The parallel sides of the trapezium are the left and right edge.
( 9 + 13) = 22
The height is the vertical distance between the parallel sides and when you turn the shape 90degrees towards the left, we would have the parallel sides been the bottom and top edge and the vertical height between will be 9
Hence the area = 1/2 × 22 × 9
= 11 ×9 = 99
You would add the unit if measure.
The scientific notation of 832,000 is <span>8.32 × (10)to the fifth power.
Have a great day!

Step-by-step explanation:
The given numbers are : 32 , 48 , 140 , 120
First number is 32
Second number is 48
Third number is 140
Fourth number is 120
First number/second number :
Third number/Fouth number :
From equation (1) and (2) we can see that the ratio is not same. Hence, they are not in proportion.
