Response:
Option B.
Step-by-step breakdown:
The general equation for the best fit line is
where a indicates the slope and b the y-intercept.
Utilizing a graphing calculator yields a=-4.54762 and b=43.7143. Hence, the equation for the best fit line can be represented as
Here,
Note: Alternatively, you can apply the following formula to compute the slope.
Accordingly, the correct choice is B.
Answer:
x = StartFraction negative (negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Step-by-step explanation:
we understand that
The quadratic equation solution formula for the structure is described as
for this particular equation we recognize
thus
insert values into the equation
therefore
x = StartFraction negative (negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Answer:
The measure of arc GH is 80 degrees.
Step-by-step explanation:
Circles F and J are congruent.Given that: m∠DFE = 80°
Angle DFE serves as the central angle of circle F.
Arc GH's measurement corresponds with the central angle from Circle J.
Since the two circles are congruent
The measure of arc GH, therefore, is 80 degrees.
Answer: It’s two trees
Step-by-step explanation:
Given that the city plants a tree every 20 feet along Dayton Avenue, we first need to establish the length of the side that faces Dayton Avenue.
We currently have three sides unaccounted for. However, it’s crucial to note that the side next to Dayton Avenue has the same length as the two unaccounted sides combined. This equivalence holds because both lengths include the 1 feather and 2 feather markers, confirming congruence.
Thus, the sum of both side lengths will be .
Consequently, the side next to Dayton Avenue measures
feet.
Having determined that this side is 57 feet long, we divide this length by 20 to find the tree planting intervals. Since the planting occurs only in complete 20-foot segments, if the division results in a decimal, we must round down. A tree is only planted if complete segments of 20 feet are reached.
This rounding process gives us 2.
I hope this clarifies!
Indeed, a fare of $40 is a fair charge for the cab ride.
Explanation
Sheri's cab fare totaled $32, with a gratuity rate of 20%.
The gratuity amount is:
Thus, the total cab fare including gratuity is:
Since Sheri issued a $40 check to the cab driver, it indicates she provided ($40 - $38.40) or an extra $1.60 to the cab driver. Consequently, the $40 payment is reasonable for the cab fare.
