deff fn [24]

Step-by-step explanation:

x+100°=180°{being straight angle}

x=180-100

x=80°

again,

45°+x+y=180°{sum of angle of triangle}

45+80+y=180

y=180-125°

y=55°

The equation of the trend line is ŷ = 0.15x - 23.21

<h3>How to determine the average rate of change of the trend line?</h3>

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w => 93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 5956
Sum of Y = 680
Mean X = 661.7778
Mean Y = 75.5556
Sum of squares (SSX) = 50569.5556
Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21

In a tutoring session, 2/3 of an hour was spent reviewing math problems. Adelina attended 3/4 of the tutoring session. How much

fgiga [73]

Answer:

Time spend by Adelina at the tutoring session is 30 minutes.

Step-by-step explanation:

Given : In a tutoring session, $\frac{2}{3}$ of an hour was spent reviewing math problems and Adelina attended $\frac{3}{4}$ of the tutoring session.

We have to find the time Adelina spend at the tutoring session.

We know, 1 hour = 60 minutes.

Total time taken in tutoring session = $\frac{2}{3}\times 60=40$ minutes.

also, Adelina attended $\frac{3}{4}$ of the tutoring session that is $\frac{3}{4}$ of 40 minutes.

that is $\frac{3}{4}\times 40=30$ minutes.

Thus, time spend by Adelina at the tutoring session is 30 minutes.
