Answer:
Step-by-step explanation:
From the figure attached,
Measure of an angle = 20°
Measure of the opposite side = x
Measure of the adjacent side = 12
By applying tangent rule in the given right triangle,
tan(20°) = 
Therefore, equation to get the value of 'x' will be,
14
Step-by-step explanation:
Area of a triangle = 1/2 ×base ×height
= 1÷2 ×(7×4)
=1÷2 ×28
=14
Answer:
set 1 =11 set 2 =208 Set 2 has the wider spread since the range is bigger
Step-by-step explanation:
range- find the largest number and subtract the smallest number from it
Set 1: 12-1 =11
Set 2: 230-22 =208
Step-by-step explanation:
Probability of event A on the condition of event B is:
P(A|B) = P(A and B) / P(B)
P(scored an A | girl) = P(scored an A and girl) / P(girl)
P(scored an A | girl) = 0.35 / 0.45
P(scored an A | girl) = 0.778
The probability that a randomly selected girl also scored an A is 77.8%.
