Answers:
∠A=45° & ∠B=45°
Step-by-step explanation:
In triangle ABC, all angles are less than 180° but their sum is 180°
For the trigonometric statements
sin(A)=cos(B)
sin(B)=cos(A)
These are true when these angles that are A and B are equal and on these angles the sin and cos value must be same.
Hence, both angles are of 45°
Answer:
Pr(≥ 70%) = 2/5 = 0.4
Step-by-step explanation:
This question is incomplete as we can't get an exact answer without the dot plot diagram.
We can tell from the question, we are to determine the probability of having ≥ 70% students that play sports
The dot plot diagram used in solving the question has been attached.
Total number of samples = 20
From the dot plot, 50% of students play sport. That is, 50% have more people playing sport than others.
The chance of getting a sample proportion of 70% or greater= probability of students that like sports ≥ 70%
= (sum of people that like sports ≥ 70%)/(total number of sample)
Pr(≥ 70%) = (4+3+1)/20
Where Pr = probability
Pr(≥ 70%) = 8/20
Pr(≥ 70%) = 2/5 = 0.4
First, solve for slope:
-7 - -8 = 1
-3 - -6 = 3
1/3 = m
Next, plug in one of your points into
y = (1/3) x + b
-7 = -1 + b
-6 = b
Answer:
y = (1/3)x-6
