Answer:
Step-by-step explanation:
Answer:
A. The reference angle should be pi/3, and the sign of the value should be negative.
Step-by-step explanation:
Just took the unit review.
Divide both sides by 2 for the first one.
2c/2>2/2
c>1
simplify both sides for the second 1
1/6d>=1
6*(1/6d).=(6)*(1)
d>=6
For the last one
subtract 9 from both sides
r+9-9<=23-9 so that r<=14
Hope this helps!
Answer:
The probability that exactly 5 are unable to complete the race is 0.1047
Step-by-step explanation:
We are given that 25% of all who enters a race do not complete.
30 have entered.
what is the probability that exactly 5 are unable to complete the race?
So, We will use binomial
Formula : 
p is the probability of success i.e. 25% = 0.25
q is the probability of failure = 1- p = 1-0.25 = 0.75
We are supposed to find the probability that exactly 5 are unable to complete the race
n = 30
r = 5



Hence the probability that exactly 5 are unable to complete the race is 0.1047
Hey there! :)
Answer:
170 cm².
Step-by-step explanation:
This is an example of a composite figure, so find the areas of each shape separately:
Begin by finding the area of the smaller square. A = s²
A = 7² = 49 cm².
Find the area of the larger square:
A = 11² = 121 cm².
Add up the two areas:
49 + 121 = 170 cm².
