Answer:

(D) 0.006

Step-by-step explanation:

Total number of cards :52

Please note that, all cards have a the possibility of appearing 4 times.

Hence total possible number of a '2' is 4 cards and so it is also for a '10'

Having this Understanding, let's solve the question properly.

The probability that the FIRST CARD is 2 = 4/52

Probability that the second card without replacement is a 10 = 4 / 51

P( 1st two and 2nd four)

4/52 * 4/51 = 4/663

= 0.0060332

Rounding to 3 decimal places = 0.006

How to get answer:

Expand -2\left(x+13\right)+9x:\quad 7x-26\\Expand -2\left(x+13\right):\quad -2x-26\\\\=-2x-26+9x\\Simplify -2x-26+9x:\quad 7x-26\\7x-26=4\\\mathrm{Add\:}26\mathrm{\:to\:both\:sides}\\7x-26+26=4+26\\\mathrm{Simplify}\\7x=30\\\\\mathrm{Divide\:both\:sides\:by\:}7\\\frac{7x}{7}=\frac{30}{7}\\Simplify\\x=\frac{30}{7}

H(x)= 9/x( x^2-49)<br> Determine the domain of the function
Norma-Jean [14]

Answer: The domain of the function h(x) = \frac{9}{x(x^2-49)} is:

Interval Notation: (-∞ , -7) ∪ (-7 , 0) ∪ (0 , 7) ∪ (7, ∞)

Set-Builder Notation: { x | x ≠ 0 , 7 , -7 }

All real numbers besides 0, 7, and -7.

Step-by-step explanation:

In order to find the domain of your rational function, we need to simplify it:

h(x) = \frac{9}{x(x^2-49)} = \frac{9}{(x)(x+7)(x-7)}

Remember, most of the time, the domain of a rational function consists of all real numbers besides zero.

To find the domain, we equal the equations in the denominator to zero.

x=0

x+7=0 --> x=-7

x-7=0 --> x=7

So all real numbers except for 0, -7, and 7 are in the domain of this rational function.

At the building site there are 16 pallets with sacks of cement the total weight of all the pallets and cement is 4856 pounds eac
inysia [295]
The first thing we must do for this case is to define a variable.
 We have then:
 x: weight of each pallet with cement
 We then have the following equation:
 16x = 4856
 Clearing x we have:
 x = (4856) / (16)
 x = 303.5 punds
 Answer:
 
each pallet with cement weigh:
 
x = 303.5 punds
