Answer:
y = 12-(61) is the answer !!
Answer:
The answer is false
Step-by-step explanation:
In a sample above 30 obs like this the confidence interval is defined as
X+- t* (s/sqrt(n)) where X is the mean t the tvalue for a given confidence level, n the size of sample and s standar deviation.
To find de appropiate value of t we must see the T table where rows are degrees of freedom and columns significance level
The significance is obtained:
significance = 1 - confidence level = 1 - 0.9 = 0.10
Degrees of freedom (df) for the inteval are
df = n - 1 = 18 - 1 = 17
So we must look for the value of a t with 17 values and significance of 0.10 which in t table is 1.740 not 1.746 ( thats the t for 16 df)

Answer:
20
Step-by-step explanation:
Given :
Length = l
Width = w
Area of square = 45
Let side of square = x
Area of square = x²
45 = x²
√45 = x
l of rectangle = x + 5 = √45 + 5
w of rectangle = x -5 = √45 -5
Area of rectangle= l * w
Area = (√45 + 5) * (√45 - 5)
Area = 45 - 5√45 + 5√45 -25
Area = 45 -25
Area of rectangle = 20
Answer:
$88.72 (89 dollars for a hat dude what a good deal. Finn officially fell for the trap. Watch episode 2 of Affording to buy a 100$ hat with Finn!)
Step-by-step explanation:
Step 1: Make an equation (98.58 x 90%)
Step 2: Solve (you can also do 98.58 x 0.9 to make it easier) and you get
$88.72
Hope this helps! :)

PS: Hopefully Finn doesn't have mental issues because he is buying a "cheap" hat.
