For the function m(n)=4n-7, when m is 9 what is n?

klio [65]

Answer:

n = 4

Step-by-step explanation:

Put the given values in the equation and solve for n.

9 = 4n -7

16 = 4n . . . . . . add 7

4 = n . . . . . . . . divide by 4

The value of n is 4 so that m(4) = 9.

When there are few data, we often fall back on personal probability. There had been just 24 space shuttle launches, all successf

Stels [109]

Answer:

Step-by-step explanation:

There are about 110,000 days in 300 years, so the expected number of failures is about 10/11 ≈ 1.

_____

This assumes the launch conditions are identical for each of the launches, or that whatever variation there might be has no effect on the probability. These are bad assumptions.

Solve for v: -v+1=1 + 8v

AfilCa [17]

Answer: v=0

Step-by-step explanation:

Because....

Step 1: Simplify both sides of the equation.

−v+ 1= 8v + 1

Step 2: Subtract 8v from both sides.

−v+1 − 8v = 8v+1 − 8v

−9v + 1 = 1

Step 3: Subtract 1 from both sides.

−9v + 1 −1 = 1−1

−9v=0

Step 4: Divide both sides by -9.

$\frac{-9v}{-9} = \frac{0}{-9}$

v=0

Therefor, the answer is v = 0

Solve the problem. six times Tim’s age is 54. His sisters age times three is also 54. How old are Tim an his sister Amy?

Semenov [28]

If $t$ is Tim's age, then $6t=54$ , so $t=9$ .

If $a$ is Amy's age, then $6a=54$ , so her age is also $a=9$ .
