Answer:

AM=1 false

BM= ½ true

AM=½ false

BM= √3/2 false

AM= ✓3/2 true

BM=1 false

Step-by-step explanation:

Since the triangle is equilateral it means that all sides are of the same length. So AB=1, BC=1, AC=1

AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM= ½ true because BC=1 so BM (half)=0,5=½

AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM= √3/2 false because it's ½

AM= ✓3/2 true because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM=1 false because BM= ½

What is the probability of selecting a red card from a standard deck of 52 playing cardships that does not contain a joker?
Rasek [7]
We know that the deck of cards contain half red and half black cards or you can say we have 26 red cards and 26 black cards.
we have to find probability of red cards from a deck of cards
so,
probability (selecting red card) = \frac{26}{52}
                                                     = \frac{1}{2}

Probability ( selecting red card ) =  <span>\frac{1}{2} Answer</span>

A hypothetical population consists of eight individuals ages 13, 14, 17, 20, 21, 22, 24, &amp; 30 years.
Alika [10]

Complete Question

A hypothetical population consists of eight individuals ages 13 14 17 20 21 22 24 30 years.  

A: what is the probability that a person in this population is a teenager?  

B: what is the probability of selecting a participant who is at least 20 years old?

We have that  probability that a person in this population is a teenager and probability of selecting a participant who is at least 20 years old is

From the question we are told

A hypothetical population consists of eight individuals ages 13, 14, 17, 20, 21, 22, 24, & 30 years.

  • P(T)=0.38
  • P(T')=0.63

a)

Generally the equation for the  probability that a person in this population is a teenager   is mathematically given as

P(T)=\frac{no of teens}{n}\\\\P(T)=\frac{3}{8}

P(T)=0.38

b)

Generally the equation for the probability of selecting a participant who is at least 20 years old  is mathematically given as

P(T)=\frac{ participants\ who\ is\ at\ least\ 20\ years old}{n}\\\\P(T)=\frac{5}{8}

P(T')=0.63
