Answer:
542.50
Step-by-step explanation:
Given:
Least square regression equation :
y = 102.50 + 0.65x + residual
y = predicted fare
x = distance in miles
Intercept = 102.50
Slope = 0.65
Distance in miles, x = 500 miles
y = 102.50 + 0.65(500) + 115
y = 102.50 + 325 + 115
y = 427.5 + 115
y = 542.50
n - 12 = -9
Add 12 to both sides to isolate the variable n.
n = -9 + 12
n = 3
B) n = 3
Simplifying the expression gives 13/ 36
<h3>How to solve the expression</h3>
Given;
1/4(1-2/3)^2+1/3
Represented as;
Take the LCM of the bracket
Find the square
Find the LCM
1 + 12/36
13/ 36
Thus, simplifying the expression gives 13/ 36

Answer:
(write this in the format your curriculum suggests, most are different)
Since BC is longer than AB, this means m<bcd is smaller than m<bad.
A way to prove it mathematically is to look at the triangle on the left. Since It's an isosceles triangle, m<cda and m<dac are equal. However, the triangle on the right does not have two proven congruent sides. All we know is BC is larger than the other side lengths. In a figure like that, the obtuse angle that meets the longest side would be the largest angle.
Apologies for being so wordy.
Answer:
200.96 ft²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius ) , then
A = 3.14 × 8² = 3.14 × 64 = 200.96 ft²
