Answer:

y = 3/4 x +1

Step-by-step explanation:

We know the y intercept (where it crosses the y axis) (0,1)

and we know another point (4,4)

We can find the slope (0,1) (4,4)

slope = (y2-y1)/(x2-x1)

= (4-1)/(4-0)

= 3/4

The equation of a line is y= mx+b where m is the slope and b is the y intercept

y = 3/4 x +1

Using mathematical operations and ratios, the number of questions that the other kids answered incorrectly was <u>1 each</u>.

<h3>What are the mathematical operations?</h3>

The mathematical operations include these four basic operations - addition, subtraction, multiplication, and division.

These mathematical operations and ratios, which set one value equal to another, are used to solve mathematical problems.

<h3>Data and Calculations:</h3>

The number of questions = 20

Marks awarded to each question = 3 points

Average incorrect answers by Chris = 6

Average performance = 50%

Above average performance = 90%

Incorrect answers by other students = 10% (1 - 90%)

<h3>Incorrect performance ratios:</h3>

Chris = 50%

Four students = 10%

= 5 : 1

Chris' ratio = 5/6

Four students = 1/6

The number of questions that the four other students answered incorrectly was <u>1 question</u> (6/50% x 10%) or (6 x 1/6).

Thus, the other kids answered <u>1 question</u> each incorrectly.

How would I find the measurement of arc CD?

Ierofanga [76]

Angle A = (arc CD - arc BC) / 2
56 degrees = (arc CD -95) / 2
112 degrees = (arc CD -95)
arc CD = 207
