Out of 1,100 discs tested, 13 are defective. Estimate the number of defective discs in a batch of 41,000.

QveST [7]

Answer:

150 people

Step-by-step explanation:

First, look over the chart and find the rows that have listed as 26 - 30 and 31 - 35.

Find out how high the row goes by looking at the number on the side of the gram.

26 - 30 goes to 60

31 - 35 goes to 90

Then add the 2 numbers together and you will find your total

60 + 90 = 150 people

Which of the following coordinates exists on the line y = 3x + 1?

Natalija [7]

We are given

equation of line as

$y=3x+1$

we will check each options

option-A:

we can plug (3,1)

x=3 and y=1

$1=3*3+1$

$1=10$

we can see that

they are not equal

so, this is FALSE

option-B:

we can plug (-1,-2)

x=-1 and y=-2

$-2=3*-1+1$

$-2=-2$

we can see that

they are equal

so, this is TRUE

option-C:

we can plug (-3,4)

x=-3 and y=4

$4=3*-3+1$

$4=-8$

we can see that

they are not equal

so, this is FALSE

option-D:

we can plug (2,6)

x=2 and y=6

$6=3*2+1$

$6=7$

we can see that

they are not equal
