Where are my smart friends?? I had $13.00. My Mom gave me $10.00. My Dad gave me $30.00. My Aunt, My Uncle, and grandma gave me

sergiy2304 [10]

Answer:

This would bring you to $160.00. This is because you initially had $20.00, because of the $13 and $7. Then, your family gave you a total of $140.00, and 140 + 20 = 160.

Express the given integral as the limit of a riemann sum but do not evaluate: the integral from 0 to 3 of the quantity x cubed m

WARRIOR [948]

We will use the right Riemann sum. We can break this integral in two parts.
$\int_{0}^{3} (x^3-6x) dx=\int_{0}^{3} x^3 dx-6\int_{0}^{3} x dx$
We take the interval and we divide it n times:
$\Delta x=\frac{b-a}{n}=\frac{3}{n}$
The area of the i-th rectangle in the right Riemann sum is:
$A_i=\Delta xf(a+i\Delta x)=\Delta x f(i\Delta x)$
For the first part of our integral we have:
$A_i=\Delta x(i\Delta x)^3=(\Delta x)^4 i^3$
For the second part we have:
$A_i=-6\Delta x(i\Delta x)=-6(\Delta x)^2i$
We can now put it all together:
$\sum_{i=1}^{i=n} [(\Delta x)^4 i^3-6(\Delta x)^2i]\\\sum_{i=1}^{i=n}[ (\frac{3}{n})^4 i^3-6(\frac{3}{n})^2i]\\
\sum_{i=1}^{i=n}(\frac{3}{n})^2i[(\frac{3}{n})^2 i^2-6]$
We can also write n-th partial sum:
$S_n=(\frac{3}{n})^4\cdot \frac{(n^2+n)^2}{4} -6(\frac{3}{n})^2\cdot \frac{n^2+n}{2}$

Ruben earns $4 an hour as a cashier and $5.50 and hour as a waiter. If he works 5 days per week, how much does he earn if he wor

34kurt

So to find how much Ruben will make if he works 4 hours a day as a cashier and 3 hours a day as a waiter for 5 days per week first we'll work on his cashier job. So he makes 4$ an hour as a cashier and her works 4 hours every day for 5 days, multiply 4 by 4 and you'll get 16, so he makes 16 dollars per day as a cashier. now that we know how much he makes a day we simply have to multiply 16 by 5 since he works for 5 days every week. 16*5 is 80, so Ruben makes 80 dollars working 4 hours a day for 5 days. Now we move onto his waiter job. he makes 5.50 an hour as a waiter and her works 3 hours a day. So we multiply 3 by 5.50 to get 16.5. Next, we multiply 16.5 by 5 since he also works 5 days a week as a waiter. 16.5*5 is equal to 82.5. now we add 82.5 and 80 to get 162.5. SO Ruben makes 162.5$ working both jobs 5 days a week

Sav [38]

Answer:

The number of tests required is 330.

Step-by-step explanation:

We have to find the total number of combinations of four wires.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.
