If a coin is tossed 30 times what is the probability of guessing right 22 times or 73% of the time?

0.545%

Step-by-step explanation:

The probability of guessing each coin toss is 50% or ½.  Using binomial probability, the probability of guessing exactly 22 coin tosses is:

P = nCr pʳ qⁿ⁻ʳ

P = ₃₀C₂₂ (½)²² (1−½)³⁰⁻²²

P ≈ 0.00545

So the probability is 0.545%.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

r and t.

both are 64 degrees.
