Answer:

x = 29 and y = 26

Mr. Micklow's age is 29 years and Ms. Craft's age is 26 years

Step-by-step explanation:

Mr. Micklow's age is x and Ms. Craft's age is y

∵ The sum of their ages is 55

∴ x + y = 55 ⇒ (1)

∵ The difference between their ages is 3

∴ x - y = 3 ⇒ (2)

Now you have a system of equation let us solve it

Add equation (1) and (2) to eliminate y

∵ (x + x) + (y - y) = (55 + 3)

∴ 2x = 58

- Divide both sides by 2

∴ x = 29

Substitute the value of x in equation (1) or (2) to find y

∵ 29 + y = 55

- Subtract 29 from both sides

∴ y = 26

Mr. Micklow's age is 29 years and Ms. Craft's age is 26 years

Mohamed decided to track the number of leaves on the tree in his backyard each year. The first year, there were 500500500 leaves

Paha777 [63]

Answer:

$f(n) = (1.4)^{(n - 1)} \times 500$

The sequence is a geometric sequence.

Step-by-step explanation:

The number of leaves in the tree in the first year is 500.

And the number of leaves in the tree in the second year increases by 40% of the number in the first year.

So, it will be $500(1 + \frac{40}{100}) = 1.4 \times 500$

Again, the number of leaves in the tree in the third year increases by 40% of the number in the second year and so on.

Therefore, the number of leaves in the tree in the third year will be $1.4 \times 500 \times (1 + \frac{40}{100}) = (1.4)^{2} \times 500$ and so on.

If we want to calculate the number of leaves in the tree in the nth year by f(n) then it will be given by

$f(n) = (1.4)^{(n - 1)} \times 500$

Therefore, the sequence is a geometric sequence. (Answer)

The number of tickets issued by a meter reader for parking-meterviolations can be modeled by a Poisson process with a rateparame

Doss [256]

Answer:

Step-by-step explanation:

Let X be the number of tickets issued by a meter reader for parking-meterviolations can be modeled by a Poisson process with a rateparameter of five per hour.

X is Poisson with parameter =5per hour

a) the probabilitythat exactly three tickets are given out during a particular hour

= $P(X=3)=0.14037$
