Suppose that 30% of a population has dimples. You want to estimate the probability that it will take at least a sample of three to find one person with dimples. You set up a random digit simulation where 0, 1, 2 represents a person with dimples and 3, 4, 5, 6, 7, 8, 9 represents a person that does not have dimples. Which would constitute a trial for this simulation? A) two random digits B) three random digits C) eight random digits D) ten random digits
This is just a step by step thing if u need: −2(1+5a)=−6(a+3)Simplify both sides of the equation.−2(1+5a)=−6(a+3)Simplify−10a−2=−6a−18Add 6a to both sides.−10a−2+6a=−6a−18+6a−4a−2=−18Add 2 to both sides.−4a−2+2=−18+2−4a=−16Divide both sides by -4.−4a−4=−16−4Your Answer would be: A=4
I' m not so sure if this is right but I got -20 + 6a
The Fairbanks,Alaska, a typical January temperature is -13F and a typical April temperature is 30F. What is the difference between these temperatures?
Answers
The difference between +30 and -13 is 43 degrees.
t- temperature in January T-temperature in April
Δ- difference beteween temperature
Δ=T-t Δ=30F-(-13F)=30F+13F=43F
Allen has a photo that is 6in by 8in what will the dimension of the photo be if he scales it down by a factor of 1\2
Answers
A photo of 6 and 8 is scaled down to 1/2 the size To find this, you multiply both by 1/2 or divide by 2 The new dimensions are 3 by 4 6 divided by 2=3 8 divided by 2=4
Can you please help me with this

The grandparents that shop at Greggslist was 3 out of the 25 sampled. That gives us a ratio of 3/25. Convert this to decimal by dividing 3 by 25 and your answer is
