Assuming that the all the cards have the same probability of being drawn we get:
A) P = 0.07B) P = 0.21C) P = 0.001How to find the probabilities?
We have a deck of 52 cards.
A) The probability of drawing an even-numbered card is given by the quotient between the number of even-numbered cards and the total number of cards.
On the 52 card deck, there are 16 even cards (2, 4, 6, 8 for each type), so the probability is:
p = 16/52
Then the probability of drawing a face card is given in the same way, notice that now there are 51 cards in the deck and 12 face cards, so we get:
q = 12/51
The joint probability is the product of these two:
P = (16/52)*(12/51) = 0.07
b) Both cards are 4 or larger.
There are 6 cards equal or larger than 4 for each type, so the probability for the first card is:
p = 24/52
For the second card, there is one card less in the deck (and one card less that is equal or larger than 4) so the probability is:
q = 23/51
The joint probability is:
P = (24/52)*(23/51) = 0.21
C) There are 6 black face cards, so the probability first is:
p = 6/52
Then there are 2 black cards with the number 5, so the probability is:
q = 2/51
The joint probability is:
P = (6/52)*(2/51) = 0.001

The product of two integers is -160 if one of them is 8 find the other
Hey ! there
Answer:
Other number is -20Step-by-step explanation:
In this question we are given that the product of two integers is -160 and one of them is 8 . And we are asked to find the other integer .
For finding the other integer we are assuming ,
Other integer as ' x 'And now we can find other Integer by making equation and solving it .
SOLUTION : -
Equation is :
[tex] \quad \dashrightarrow \qquad \: 8 \times x = - 160[/tex]
or ,
[tex] \quad \dashrightarrow \qquad \: 8x = - 160[/tex]
To isolate the variable x , We are dividing both sides by 8 :
[tex] \quad \dashrightarrow \qquad \: \dfrac{ \cancel{8}x}{ \cancel{8}} = \cancel{ \dfrac{ - 160}{8} }[/tex]
On simplifying it , We get :
[tex] \quad \dashrightarrow \qquad \: \red{\underline{\boxed{\frak{x = - 20}}}} \quad \bigstar[/tex]
Henceforth , the other integer is ❝ -20 ❞.Verifying : -
Now we are verifying whether our answer is wrong or right by substituting value of x in the equation . So ,
[tex]8 \times x = - 160[/tex]Substituting value of x :
[tex]8 \times - 20 = - 160[/tex]Multiplying 8 with - 20 :

If the cans are divided evenly among the shelves, how many cans are on each shelf?
Cans for sale: 1,200
Shelves of cans: 10
Rows per shelf: 6
To distribute 1,200 cans evenly among 10 shelves, with each shelf having 6 rows, we find that there are 120 cans on each shelf.
To find the number of cans on each shelf, we need to divide the total number of cans (1,200) by the total number of shelves (10) and the number of rows per shelf (6).
First, calculate the total number of cans in each shelf by multiplying the number of rows per shelf by the number of cans in each row:
Cans per shelf = Rows per shelf * Cans in each row
Cans per shelf = 6 * 200 = 1,200
Now, divide the total number of cans (1,200) by the total number of shelves (10):
Cans on each shelf = Total number of cans / Total number of shelves
Cans on each shelf = 1,200 / 10 = 120
So, there are 120 cans on each shelf when the cans are divided evenly among the shelves.

x² + 8² = (2√41)²x² + 64 = 4(41)x² + 64 = 164x² = 100x = 10Given the function f(x) = 3|x – 2| 6, for what values of x is f(x) = 18?
The values of x in f(x) = 3|x - 2| + 6 when f(x) = 18 are 6 and -2
How to determine the value of x?The function is given as:
f(x) = 3|x - 2| + 6
The value of f(x) is
f(x) = 18
So, we have:
3|x - 2| + 6 = 18
Subtract 6 from both sides
3|x - 2| = 12
Divide both sides by 3
|x - 2| = 4
Remove the absolute bracket
x - 2 = 4 or x - 2 = -4
Add 2 to both sides
x = 6 or x = -2
Hence, the values of x are 6 and -2

An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the obtcome of a single trial of a random experiment. Compute the probability of each of the following events. Event A: The sum is greater than 6. Event B: The sum is divisible by 4. Write your answers as fractions.
Answers:
P(A) = 7/12
P(B) = 1/4
====================================================
Explanation:
Instead of having one die, let's say we have two dice. I'll make one red and the other blue.
I'll be using the dice chart shown below. The red and blue values add up to the black numbers inside the table. For instance, we have 1+1 = 2 in the upper left corner. There are 6*6 = 36 sums total.
Using that table, we can see the following:
There are 6 copies of "7"There are 5 copies of "8"There are 4 copies of "9"There are 3 copies of "10"There are 2 copies of "11"There is 1 copy of "12"In total, we have 6+5+4+3+2+1 = 21 instances where the two dice add to something larger than 6.
This is out of 36 ways to roll two dice.
Therefore P(A) = 21/36 = (3*7)/(3*12) = 7/12
-----------------------------------
If a number is divisible by 4, then it is a multiple of 4.
The multiples of 4 found in the table are: 4, 8, 12
We have
3 copies of "4"5 copies of "8"1 copy of "12"This gives 1+5+3 = 9 values that are a multiple of 4
P(B) = 9/36 = (1*9)/(4*9) = 1/4
Given: X= 0.234523452345..... Is X rational or irrational? a If X is rational, rewrite it in a fraction.
WILL GET BRAINLIEST!!!!!!
Answer:
[tex]\sf X=\dfrac{2345}{9999}[/tex]
Step-by-step explanation:
Given:
[tex]\sf X=0.234523452345...[/tex]
Therefore, X is a recurring decimal (the decimal numbers 2345 repeat forever).
Converting a recurring decimal to a fraction
Let X equal the recurring decimal:
[tex]\implies \sf X=0.234523452345...[/tex]
Create another number with recurring 2345s by multiplying the above expression by 10000:
[tex]\implies \sf 10000X=2345.23452345...[/tex]
To solve these two equations and write X as a fraction, take away X from 10000X to remove all the recurring decimal places:
[tex]\large\begin{array}{r r l}& \sf 10000X & = \sf 2345.23452345... \\- & \sf X & = \sf \quad \:\:\:0.23452345.... \\\cline{2-3} & \sf 9999X & = \sf 2345\end{array}[/tex]
[tex]\implies \sf 9999X=2345[/tex]
Divide both sides by 9999:
[tex]\implies \sf X=\dfrac{2345}{9999}[/tex]
Therefore, 0.23452345... as a fraction is [tex]\sf \dfrac{2345}{9999}[/tex]

Carl used 10 2/9 of an inch of string to tie a parcel and another 5 1/4 of an inch of string to tie a box, how much string is left if he started with 20 inches?
(please put you solution)
Answer:
4 19/36
Step-by-step explanation:
we have to subtract the sum of 10 2/9 and 5 1/4 from 20 to get the answer.
=> 10 2/9 + 5 1/4
As a c/d is a + c/d,
10 2/9 + 5 1/4 can also be written as 10+5+2/9+1/4
now we have to simplify it
=> 10+5 = 15
=> 2/9 = (2*4)/9*4) = 8/36, 1/4 = (1*9)/(4*9) = 9/36
now we have the same denominators
add,
8/36 + 9/36 = (8+9)/36 = 17/36
=> now we know that 10 2/9 + 5 1/4 is 15 17/36 ( which is 15 + 17/36)
=> next step is to convert 15 17/36 into an improper fraction
15 17/36 = [(15*36)+17]/36 = [540+17]/36 = 557/36
=> now we just have to subtract 557/26 from 20
20 - 557/36 = [(20*36)-557]/36 = [720-557]/36 = 163/36
=> we can convert 163/36 into a mixed fraction if we want to
163/36 converted into mixed fraction is 4 19/36
