The perimeter is just all the lines around the outside of the shape so basically take all the numbers and add them together to get the answer
Distribute the five to [3q-10]
Combine like terms [15q] and [-5q]
Add 50 on each side
Divide by 10 on each side
Simplify
To find the domain, you first need to find what x values will result in an imaginary number. To find this, solve the inequality -13-x >(or equal to)0. This comes out to x<(or equal to) -13. This means that’s the domain is [-13, negative infinity).
Answer:
The margin of error at 90% confidence is 0.5133 gram.
Step-by-step explanation:
Margin of error (E) = (critical value × sample standard deviation) ÷ sqrt(n)
sample standard deviation = 1.5 grams
confidence level = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
n (sample size) = 25
degree of freedom = n - 1 = 25 - 1 = 24
critical value (t) corresponding to 24 degrees of freedom and 10% significance level is 1.711
E = (1.711×1.5) ÷ sqrt(25) = 2.5665 ÷ 5 = 0.5133 gram
The answer you are looking for is A) Y=2x-2
