Answer:
The answer is -8
Step-by-step explanation:
Subtracting 8x from both sides to get Y by itself, you would get
Y= -8X + 10, and we know that y=mx+b, where M is the slope, therefore -8 is M and the slope is -8.
Triangle is 180
therefore you have 180 > m<1 >56
Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>The equation for simple interest:</u>
<u>And values</u>
<h3>Solution</h3>
<u>Interest amount is</u>
<u>Solving for annual interest rate</u>
- 160 = 2000*2r
- 160 = 4000r
- r = 160/4000
- r = 0.04
- 0.04*100% = 4%
Annual interest rate is 4%
When x is -4:
y=-3(-4)+4
y=16
-2:
y=-3(-2)+4
y=-2
0:
y=-3(0)+4
y=4
2:
y=-3x2+4
-2
Hope that helps
Answer:
The secondary attack rate is 55%
Step-by-step explanation:
Total number of students = 83
Primary cases: cases A+B+C = 3 primary cases.
Secondary cases = 44
Total cases = 44 + 3 = 47
To find the secondary attack rate, we are to assume that the primary cases are now immune because they had the illness.
We have:
Secondary attack rate = 
The secondary attack rate is 55%
