Answer:
F) 6/5
Step-by-step explanation:
6 divided by 5 = 6/5
Step-by-step explanation:
12a+24a=180
36a = 180
a =5 °
angle of yzv = 24a = 120°
Answer:
x=2 y= -3
Step-by-step explanation:
Answer:
z = 110
Step-by-step explanation:
The measure of an angle created by the intersection of two secants outside a circle is half the difference of the angles it intercepts. In this it would be:
2x + 15 = 1/2 * (10x + 20 - 80)
We can now solve:
4x + 30 = 10x - 60
30 = 6x - 60
6x = 90
x = 15
This means the values of 10x + 20 is 10(15) + 20, which is 170.
Now, we can add up all the arcs in a circle, which sum to 360 degrees:
360 = z + 170 + 80
360 = z + 250
z = 110
Answer:
b. mode = 88, median = 77
Step-by-step explanation:
First, arrange all the numbers least to greatest.
53, 71, 75, 79, 88, 88
The mode is the number that occurs the most.
mode = 88
The median is the middle number. Since there is an even number of numbers, look at the two middle numbers 75 and 79. Add them together and divide by two (finding the average or mean of the numbers).
75 + 79 = 154
154/2 = 77
median = 77
