3 * 6 = 18 . . . . . ways up and down.

your last five customer interactions lasted 2,3,6,8 and 4 minutes that means I've averaged how many minutes across those five in

jeka94

We are given different amount of time that a customer interacted with a person (you) and we asked to get the average of those time.
Simply, we add all the data and divide it by the total number of data.
So,
average = (2 + 3 + 6 + 8 + 4) / 5
average = 23 / 5
average = 4.6 minutes

How do you work out -4(-5-b)=1/3(b+16)

Umnica [9.8K]

First multiply the parenthesis:

20 - b = 1/3b + 16/3

Then combine like terms:

20 -b + b = 1/3b + b + 16/3

20 - 16/3 = 1/3b + b + 16/3 -16/3

20 - 16/3 = 1/3b + b

44/3 = 4/3b

and if your looking for b;

44/3 (divided by) 4/3 = b

11 = b...is your final answer!

hope it helped :)

Find the value of y, if the distance travelled<br> between the peints (2, y) and (-4, 3) is 10..

Rudiy27

Answer: y=11.

Step-by-step explanation:

$(2;y_1)\ \ \ \ (-4;3)\ \ \ \ \ L=10\ \ \ \ \ y_1 > 0\ \ \ \ y_1=?\\The\ distance\ travelled\ between\ the\ peints:\\L=\sqrt{(x_2-x_1)^2+(y_2-y_1)}\\ 10=\sqrt{(-4-2)^2+(3-y_1)^2}\\ 10=\sqrt{(-6)^2+3^2-2*3*y_1+y_1^2}\\ 10=\sqrt{36+9-6y_1+y_1^2} \\10=\sqrt{45-6y_1+y_1^2}\\10*10= \sqrt{45-6y_1+y_1^2}*\sqrt{45-6y_1+y_1^2}\\100=45-6y_1+y^2_1\\$

$y^2-6y_1+45=100\\y_1^2-6y_1-55=0\\y^2_1-6y_1-5y+5y-55=0\\y^2_1-11y_1+5y_1-55=0\\y_1*(y_1-11)+5*(y_1-11)=0\\(y_1-11)*(y_1+5)=0\\y_1-11=0\\y_1=11.\\y_1+5=0\\y_1=-5\notin\ (y_1 > 0).$

The temperature, t, in degrees celsius, in a warehouse changes according to the function t(h) = 18 + 4sin(pi/12 (x = 8)).

egoroff_w [7]

The rate at which the temperature is changing at 9 a.m. is 19.03 degrees Celsius per hour

<h3>How to determine the rate at 9a.m?</h3>

The function is given as:

$t(h) = 18 + 4\sin(\pi/12(x - 8))$

9a.m is 9 hours since midnight.

This means that

x = 9

So, we have:

$t(h) = 18 + 4\sin(\pi/12(9 - 8))$

Evaluate

$t(h) = 18 + 4\sin(0.262)$

Evaluate the expression

t(h) = 19.03

Hence, the rate at which the temperature is changing at 9 a.m. is 19.03 degrees Celsius per hour
