Answer:

D

Step-by-step explanation:

so they ran the trial ten times so now you have to aks how many times did they get heads

which would be 2/10 times

you want the accuracy of which they got so divide 2/10

we know the probability of getting heads is 50%

so when you calulate it, it will give you 0.2 use the percent button and get 0.1

The formula for any geometric sequence is a n = a 1 · r n - 1 , where a n represents the value of the nth term, a 1 represents t
AfilCa [17]

Answer:

Step-by-step explanation:instead, try making the subscripts and superscripts stand out:

                         n-1

a    =  a         * r

 n         n-1

Believe me, it's worth the extra work to do this!!

Given the sequence   -3, -6, -12, -24, you can easily see that the first term,

a         is    -3.  The common factor is 2.  Note how (-3)*2=-6, and so on.

  1

So, a       = -3 and r=2.

        1

So the formula for this geometric sequence is  

                  n-1

a     =  -3*2

  n

Question 7<br> #7) What value of m makes the equation true?<br> 3(8 – m) = 5m – 40
Anastaziya [24]

Answer:

8

Step-by-step explanation:

3(8-m)=5m-40

you first distribute 3 through the parenthesis

24-3m=5m-40

Move the variable to the left and change sign

24-3m-5m=-40

now move the constant to the right

-3m-5m=-40-24

collect like terms

-8m=-40-24

-8m=-64

Divide both sides by -8 and negative divide negative number becomes positive

so m = 8
