Answer:

After a 90% increase, there is 2,280
After a 55% increase, there is 2015
After a 58% decrease, there is 588

Step-by-step explanation:

Assume the original figures are x.

After a 90% increase, there is 2,280:

x * (1 + 90%) = 2,280

1.9x = 2,280

x = 2,280 / 1.9

= 1,200

After a 58% decrease, there is 588:

x * (1 - 58%) = 588

0.42x = 588

x = 588/0.42

x = 1,400

After a 55% increase, there is 2,015:

x * (1 + 55%) = 2,015

1.55x = 2,015

x = 2,015/1.55

x= 1,300

Order:

1,200 ⇒ 1,300 ⇒ 1,400

What is the slope of the line that is represented by the values in the table above?

denpristay [2]

Answer:

$slope (m) = 6$

Step-by-step explanation:

To get the slope of the line of the given table of values, all we need is just 2 coordinate pairs from the table. We can pick any two.

Let's use, (-1, 0), and (0, 6).

Apply the formula, $\frac{y_2 - y_1}{x_2 - x_1}$ , where,

$(-1, 0) = (x_1, y_1)$

$(0, 6) = (x_2, y_2)$

Thus:

$m = \frac{6 - 0}{0 - (-1)}$

$m = \frac{6}{1}$

$slope (m) = 6$

A cable car starts off with n riders. The times between successive stops of the car are independent exponential random variables

nikitadnepr [17]

Answer:

The distribution is $\frac{\lambda^{n}e^{- \lambda t}t^{n - 1}}{(n - 1)!}$

Solution:

As per the question:

Total no. of riders = n

Now, suppose the $T_{i}$ is the time between the departure of the rider i - 1 and i from the cable car.

where

$T_{i}$ = independent exponential random variable whose rate is $\lambda$

The general form is given by:

$T_{i} = \lambda e^{- lambda}$

(a) Now, the time distribution of the last rider is given as the sum total of the time of each rider:

$S_{n} = T_{1} + T_{2} + ........ + T_{n}$

$S_{n} = \sum_{i}^{n} T_{n}$

Now, the sum of the exponential random variable with $\lambda$ with rate $\lambda$ is given by:

$S_{n} = f(t:n, \lamda) = \frac{\lambda^{n}e^{- \lambda t}t^{n - 1}}{(n - 1)!}$

Jocelyn desires to increase both her protein consumption and caloric intake. She desires to have at least 35 more grams of prote

borishaifa [10]

Yes, she could. By eating 1 ounce of cheddar cheese and 3 ounces of Parmesan cheese, she would be consuming 40 grams of protein and 176 calories.

Whats is the answer to 6×4?

Kazeer [188]

6x4=24

Multiplication is just repeating addition! For example, you can use repetitive (repeating) addition to solve 6x4.

6+6+6+6=24

I added 6 4 times to get to 24. I added it four times because you are multiplying 6 by 4! I am adding 6 (the first number) 4 times (the second number)!

Other examples:

1 x 7=7 because 1+1+1+1+1+1+1=7

2x2=4 because 2+2=4

I hope this helped! :)
