What is the probability of pulling a card that is not an odd numbered card from a deck of cards?

leva [86]

Total number of cards = 52
Number of odd cards in one set = 4
Number of odd cards in total 4 sets= 4*4=16
52-16 = 36 = number of not odd cards
36/52 = 9/13

Urgent answer please <br> Ax+ay+xa+ya

marin [14]

Answer:

Possible derivation:

d/dx(a x + a y(x) + x a + y(x) a)

Rewrite the expression: a x + a y(x) + x a + y(x) a = 2 a x + 2 a y(x):

= d/dx(2 a x + 2 a y(x))

Differentiate the sum term by term and factor out constants:

= 2 a (d/dx(x)) + 2 a (d/dx(y(x)))

The derivative of x is 1:

= 2 a (d/dx(y(x))) + 1 2 a

Using the chain rule, d/dx(y(x)) = (dy(u))/(du) (du)/(dx), where u = x and d/(du)(y(u)) = y'(u):

= 2 a + d/dx(x) y'(x) 2 a

The derivative of x is 1:

= 2 a + 1 2 a y'(x)

Simplify the expression:

= 2 a + 2 a y'(x)

Simplify the expression:

Answer: = 2 a

3 3/8 divided by 3/4 using cross multiplication algorithm

Bogdan [553]

Answer

3 3/8 ÷ (3/4) = (9/2) = 4 ½

Explanation

We are asked to evaluate 3 3/8 divided by 3/4 using cross multiplication algorithm.

The algorithm will need us to put the mixed fraction in definite fraction form (improper fraction) and to evaluate the division, we change the division sign into multiplication sign and the fraction after the division sign changes into its reciprocal.

3 3/8 = (27/8)

(3 3/8) ÷ (3/4)

= (27/8) ÷ (3/4)

$\begin{gathered} \frac{27}{8}\div\frac{3}{4} \\ =\frac{27}{8}\times\frac{4}{3} \\ =\frac{108}{24} \\ \text{Divide numerator and denominator by 12} \\ \frac{108}{24}=\frac{9}{2} \end{gathered}$

Hope this Helps!!!

Find the simple interest owed for the use of the money. Assume 360 days in a year. P=16,500, r=6%, t=180 days

Taya2010 [7]

The formula for simple interest is the following:

$S=Prt$

In this formula, $S$ is the amount of interest, $P$ is the principal (or initial) amount, $r$ is the interest rate, and $t$ is the length f time, typically in years.

First, let's make a couple of changes to how we wrote down the variables.

Change the interest rate, $6\%$ , to the decimal value $0.06$ .
Convert the length of time to years. 180 days divided by 360 days per year equals $0.5$ years.

Substitute in the values and solve with a calculator.

$\begin{aligned}S&=16,500\cdot0.06\cdot0.5\\&=\boxed{495}\end{aligned}$
