Answer:

b = 3.1

Step-by-step explanation:

Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.

2(6.3) + b = 15.7

12.6 + b = 15.7

b = 15.7 - 12.6

Magan decides to research the relationship between the length in inches and the
GrogVix [38]

Based on the line of best fit, the length of this catfish can be predicted to be 38 inches.

<u>Given the following data:</u>

  • Weight of catfish, x = 40 pounds.

<h3>What is a line of best fit?</h3>

A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any correlation between a data.

From the graph of the data, we have the following linear equation:

y=\frac{1}{2} x+18

Substituting the value of x, we have:

y=(\frac{1}{2} \times 40 )+18\\\\y=20+18

y = 38 inches.

What is the value of x? x = 23   x = 35 x = 58 x = 93
Akimi4 [234]

we know that

m∠SQR+x=180 -------> by supplementary angles

so

m∠SQR=180-x

The sum of the internal angles of a triangle is equal to 180 degrees

m∠SQR+m∠QSR+m∠SRQ=180

substitute the values in the formula

m∠SQR+35+58=180

m∠SQR=87 degrees

<u>Find the value of x</u>

m∠SQR=180-x

x=180-m∠SQR

x=180-87

x=93 degrees

therefore

<u>the answer is</u>

the value of x is 93 degrees
