You are standing on a middle rung of a ladder. If you first climb up 3 rungs, then down 5 rungs, and then up 10 rungs, how many

Answer:

The total number of rungs on the ladder are 16 rungs .

Step-by-step explanation:

Given as :

At first the climb up number of ladder = 3 rungs

At second the climb down number of ladder = 5 rungs

At third the climb up number of ladder = 10 rungs

Let The total number of rungs on the ladder = x

Now, According to question ,

The total number of climb up ladder = First + Third

I.e The total number of climb up ladder = 3 + 10 = 13 rungs

And The total number of climb down ladder = 5 rungs

So ,  From the middle of rungs =  total number of climb up ladder -  total number of climb down ladder

I.e \dfrac{x}{2} = 13 rungs - 5 rungs

∴ x = 8 × 2 rungs

I.e x = 16

Hence The total number of rungs on the ladder are 16 rungs . Answer

A store opens at 8am. From 8 until 10 customers arrive at a Poisson rate of four an hour. Between 10 and 12, they arrive at a Po
SVETLANKA909090 [29]

Answer:

The probability distribution of the number of customers that enter the store on a given day is:

P(x=k)=\frac{57^ke^{-57}}{k!}

Step-by-step explanation:

To calculate a parameter for the given day, we have to calculate what is the average arrival rate for the day.

This can be done with the data given:

1) From 10 to 12, 8 arrival/hour:  16 expected arrivals in this period

2) From 12 to 2, 8 to 12 arrival/hour (average: 10 arrivals): 20 expected arrivals in this period.

3) From 2 to 5, from 10 to 4 arrival/hour (average: 7 arrivals): 21 expected arrivals in this period.

The total expected arrivals in a day are: 16+20+21=57 arrivals/day.

Then, the probability distribution of the number of customers that enter the store on a given day is:

P(x=k)=\frac{57^ke^{-57}}{k!}

3t+1> 3t + 2

Subtract 3t from each side

1>2

This is never true so there is no solution

Since the variable terms are the same, we only have to look at the constants

Jasmine borrowed $15,000 for 8 years and she paid $6,600 in interest. What was the interest rate for Jasmine's loan?
weeeeeb [17]

Answer:

5.5%

Step-by-step explanation:

To find the interest rate, use the equation:  I = prt

I = Interest = $6,600

p = principal = $15,000

r = rate = unknown

t = time = 8 years


Now plug the numbers into the equation.

6,600 = 15,000 * r * 8

6,600 = 120,000 * r


Now isolate the variable by dividing both sides of the equation by 120,000.

0.055 = r


Now change the rate to a percent by moving the decimal point 2 digits to the right.

5.5% = r   OR   r = 5.5%
