Slope = -1
x-intercept = 3/-1 = -3.00000
f-intercept = 3/-1 = -3.00000
Slope = 0.667/2.000 = 0.333
x-intercept = 3/-1 = -3.00000
f-intercept = 3/3 = 1
Slope = 0.400/2.000 = 0.200
x-intercept = 3/-1 = -3.00000
f-intercept = 3/5 = 0.60000
Slope = 0.286/2.000 = 0.143
x-intercept = 3/-1 = -3.00000
f-intercept = 3/7 = 0.42857
Answer:
1
Step-by-step explanation:
To solve this, first, take 22 minutes and divide it by 60 minutes, which is the number of minutes in an hour. Then, add two to the value, and multiply it by six square meters per hour, which is the rate that David can paint the wall. From there, you get 14.2 square meters which he painted in 2 hours and 22 minutes. Divide 14.2 square meters by the length of 11 meters to get 1.290 meters. Since they asked you to round to the nearest meter, you get 1 meter.

Answer:
<h3>-10a² + 5a</h3>
Step-by-step explanation:
Given the expression (–5a)(2a – 1)
Open the bracket
(–5a)(2a – 1)
= -5a(2a) -5a(-1)
= -10a² + 5a
<em>hence the equivalent expression is -10a² + 5a</em>
E=Z*sqrt (p(1-p)/N), where E= error margin, p=proportion, N=sample size
Katrina's margin error at 85% confidence interval: E=1.96*sqrt (p(1-p)/100) = 0.196 sqrt (1(1-p))
Mathew's margin error at 99% confidence interval: E= 2.58*sqrt (p(1-p)/400) = 0.129 sqrt (p(1-p))
Since both obtained same estimate of proportion (that is, value of p), it can be seen that Mathew's estimate will have a small error (That is, 0.129 is smaller than 0.196). This can be attributed to larger sample size although a wider confidence (99%) interval was considered.
