Answer:

<u>The equation is:</u>

  • y = mx + b

<u>We have two points:</u>

  • (310, 68) and (620, 99)

A)

<u>Find the slope using these two points:</u>

  • m = (99 - 68)/(620 - 310) = 31/310 = 0.1

<u>Use one of the points to find the y-intercept b:</u>

  • 68 = 0.1*310 + b
  • 68 = 31 + b
  • b = 68 - 31
  • b = 37

<u>The equation is:</u>

  • y = 0.1x + 37

B)

<u>Find the value of y when x = 980:</u>

  • y = 0.1*980 + 37
  • y = 98 + 37
  • y = 135

The total cost is $135

A factory has four machines that produce the same item. Machines 1 and 2 each produce 20% of the total output, while machines 3
andrezito [222]

Answer:

The answers are a. 0.27 b. 0.2 c. 0.2 d. 0.3 e. 0.3 f. 1

Step-by-step explanation:

Total output = 100% = 1

Total defective = 6% + 5% + 8% + 8% = 27% = 27

a. Prob of defective item = total defective/total output

= 27/100

= 0.27

b. Prob of defective from machine 1 = 6/27 =0.2222

~ 0.2

c. Prob of item defective from machine2 = 5/27 = 0.1852

~0.2

d. Prob of de defective from machine 3 = 8/27 = 0.2963

~0.3

e. Prob of defective from machine 4

= 8/27 = 0.2963

~ 0.3

f. Sum of prob from b-e

0.2 + 0.2 + 0.3 + 0.3

= 1

Which reason best describes why you can divide any number by 100 by moving the decimal point two places to the left?
11111nata11111 [884]
The last choice is the reason, but to add to this, you are taking a value and breaking it into groups of 100( which is 10 groups of 10). Each place value in our decimal system naturally is based on a system of tens! Dividing by 100, is 2 groups of tens (2 decimal moves).

A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is ? units. The point (-
olganol [36]
Hello,

The circle has like equation: (x+3)²+(y-2)²=r²

If x=1 then y=5 ==>(1+3)²+(5-2)²=r²==>4²+3²=r²==>r=5 (the radius)

if x=-7 then (-7+3)²+(y-2)²=25 ==>  (y-2)²=25-16==>y=2+3 or y=2-3
The points (-7,5) and (-7,-1) are on the circle.
