Problem 1 [4 pts]: The maintenance cost of machines are uniformly distributed from 0 to 160 (dollars). If a random sample of 75

Andru [333]

Answer:

$6,000

Step-by-step explanation:

The mean value of a sample is assumed to be the same as the mean of the population. The mean of a uniformly distributed variable between 0 and 160 is:

$M = \frac{0+160}{2}\\ M=\$80$

If the mean cost for each machine is $80, the mean aggregate cost for a sample of 75 machines is:

$M_{75}=75*\$80\\M_{75}=\$6,000$

The mean aggregate maintenance cost is $6,000.

There are 64 animals at the zoo. ⅜ of the animals are birds. How many birds are at the zoo?

xxTIMURxx [149]

Answer:

Step-by-step explanation:

3/8 of the 64 total animals at the zoo are birds.

To solve, this, multiply 3/8 and 64

3/8*64=24

Another way to solve would be to make a proportion

3/8=x/64

Multiply both sides by 64 to get x by itself

64(3/8)=(x/64)64

24=x

So, 24 out of the 64 animals are birds

Solve the inequality.

frutty [35]

Answer:

$\boxed{\boxed{\sf x>-7}}$

Step-by-step explanation:

$\sf -5x-7$

Add 7 to both sides:

$\sf -5x-7+7$

$\sf -5x$

Multiply both sides by -1:

$\sf \left(-5x\right)\left(-1\right)>35\left(-1\right)$

$\sf 5x>-35$

Divide both sides by 5:

$\sf \cfrac{5x}{5}>\cfrac{-35}{5}$

$\sf x>-7$
