Answer: To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Step-by-step explanation:
Answer:
slope = 8, y- intercept = 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Given
- 8x + y = 5 ( add 8x to both sides )
y = 8x + 5 ← in slope- intercept form
with slope m = 8 and y- intercept c = 5
1) The probability of rolling a 1 is 10/40 and the probability of rolling a 5 is 6/40. Add these together to get 16/40 which simplifies to 2/5 probability of rolling a 1 or 5.
2) The probability of the spinner landing on section 2 is 36/80 which simplifies to 9/20
3) To find the relative frequency, divide each number by the total number of trials. In this case we're only look at the clubs so divide 8/40, which is 0.2 or 20%
4) There were 60 trials total and since we're finding the relative frequency of red, divide 13/60 which is 0.216 rounded to 0.22 or 22%
5) The spinner is spun 84 times and it lands on A 14 times so the probability of it landing on A is 14/84 which simplifies to 1/6 or 0.166 rounded to 0.17 or 17%
I hope this helps you!
