Step-by-step explanation:
4.
Solve for either of the variable. I solved for c because it looked easier.
Set c = 0 to solve for the x-intercept so that you can graph it. c is just your y-value in this case and m is your x-value.
I got m=90 which means it crosses the x-axis at 90. I also know it cross the y-axis at 90 because c = 90 - m is in the form of slope-intercept formula. The 90 in there is the y-intercept.
The sign is a > so it's a dotted line shaded above the graph.
5.
Same process as part 4. Set c=0 to find the x-intercept. I got m=100 which means it cross the x-axis at 100.
The y-intercept is in the equation itself c = 80 - 4/5m. The y-intercept is 80.
The sign is a ≥ so it's a solid line shaded above the graph.

13×4= 52
You have to calculate the probability for the given average:
= 3/200 = 0.015 = 1.5%
For 50,000 phones you have to multiply the probability by 50,000:
0.015*50,000 = 750 phone defectives if the company produced 50,000
Answer:
52.8 degree
Step-by-step explanation:
x²=1.9²+2.5²
x²=9.86
x = 3.14 this is SQ
using the sine rule :
sin90/3.14 = sinx/2.5
cross multiply
after cross multiply if you are allowed to use a calculator insert shift sin
you only use this when you want to find the unknown sine angle
