Answer:
x = 70
Step-by-step explanation:
The chord- chord angle x is half the sum of the arcs intercepted by the angle and its vertical angle, then
x = 
(80 + 60) = 0.5 × 140 = 70
Total the number of tenth graders: 12 + 14 + 8 = 34 total.
Now divide the number of tenth graders who speak Spanish by the total number of tenth graders:
12 / 34 = 0.3529
Multiply the decimal answer by 100 to get the percent:
03529 x 100 = 35.29%
Round to the nearest tenth = 35.3%
The answer is the first choice.
1- expand
4p= 24p + 30
2- move 24p to the other side
4p-24p=30
-20p=30
3- Divide
P= -3/2
Hope this helped!
Answer:
P = 10/171
P = 0.058
The probability that both fish selected are Catfish is 0.0058
Step-by-step explanation:
Given:
The tank contains;
Algae eaters = 8
Catfish = 5
Tilapia fish = 6
Total number of fish = 8+5+6= 19
To determine the probability that both fish selected are Catfish P;
P = 5/19 × 4/18
( The number of the total number of fishes, and Catfish reduce by one after each selection because it is selected without replacement)
P = 10/171
P = 0.058
Yes I think it will be 315
