A card is drawn at random from a standard pack of 52 playing cards find the probity of drawing a heart or a club
Answer:
1/2
Step-by-step explanation:
From the question, there are 13 cards of heart and 13 card of club in each suit in each deck.
P(drawing heart) = 13/52
P(drawing club) = 13/52
And we know total standard pack =52
P(drawing a heart or a club)
= number of favourable outcome/ total Number of outcome
P( drawing heart or club) =( 13+13)/52
=26/52
=1/2
Can you find the slope and type the correct code?
Answer:
1. (3,19) and (-1,-13)
to find the slope you need to do [tex]\frac{y2-y1}{x2-x1}[/tex]
Hence [tex]\frac{-13-19}{-1-3}[/tex]= 32/-4=-8
2. Take two points on the graph:
(-2,3) and (1,0)
Know that to calculate the slope you do
[tex]\frac{rise}{run}[/tex]= 4/2= 2
3. To find the slope in a table you need to choose any two points and utilize the following formula: [tex]\frac{y2-y1}{x2-x1}[/tex]= [tex]\frac{-16-(-8)}{2-1}[/tex]=-8/1= -8
4. Like in #1 we take the two points and plug it into the formula:
[tex]\frac{8-(-10)}{0-9}[/tex]=18/-9= -2

Is (x+1)/x^2 greater or less or equal to 1/x
Answer:
(1) x^2 is greater than 1.
(2) x is greater than -1.
(1) x^2 is greater than 1 --> x2>1x2>1 --> x<−1x<−1 or x>1x>1. Sufficient.
(2) x is greater than -1 --> x>−1x>−1. Not sufficient.

"A number x increased by 6, and then doubled."
A)
2x + 6
B
B)
2x - 6
2(x + 6)
D)
246 - x)
Answer:
(X + 6 ) ×2
It is given in the question that the no. is increased by 6 so if we take the no. as X the new no. formed is X + 6 now on doubling it the answer we get is. 2(X+6)
The correct algebraic expression is option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.
Given that : "a number x increased by 6, and then doubled," perform the operations in the correct order.
To represent the given scenario of "a number x increased by 6, and then doubled," required to follow the steps:
Step 1:
Let the number be x.
Increase the number x by 6:
x + 6.
Step 2 :
Double the result by multiply the expression:
(x + 6)2,
Remove brackets by BODMASS gives:
2* x + 2 *6
On multiplying gives:
2x+12
ON taking common factors 2 gives:
2(x+6)
Therefore, the correct expression is 2(x + 6).
Option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.

Which expression is equivalent to 20c-8d? Show all work and circle letter of correct answer.
2(10c+4d)
4(5c-8d)
4(5c-2d)
c(20-8d)
Answer correctly and get brainiest
Answer: This one is equal to what we were looking for.
4 × 5c = 20 - 8d = 12
Step-by-step explanation:
(20c - 8d = 12) so we are look for an expression that is equal to 20c 8d and 12
2 × 10c = 20 + 4d = 24
4 × 5c = 20 - 8d = 12
4 × 5c = 20 - 2d = 18
c20 - 8d = 12
Eighteen is six less than four times a number. (write and solve the equation - use x as your variable) *
Answer:
x = 6
Step-by-step explanation:
The given statement is "Eighteen is six less than four times a number".
Let the number be x.
ATQ,
18 = 4x-6
Taking like terms together,
18+6 = 4x
24 = 4x
x = 6
Hence, the value of x is 6.
For students majoring in Hospitality Management, it was determined that 5% have visited 1–10 states, 16% have visited 11–20 states, 45% have visited 21–30 states, 19% have visited 31–40 states, and 15% have visited 41–50 states. Suppose a Hospitality Management student is randomly picked. What is the probability that the student has visited 30 or fewer states?
9514 1404 393
Answer:
66%
Step-by-step explanation:
The categories are mutually exclusive, so we have ...
P(≤30) = P(1–10) +P(10–20) +P(20–30) = 5% +16% +45%
P(≤30) = 66%
The probability is 66% that a randomly chosen student has visited 30 or fewer states.

The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3. Find the distance of PQ.
Answer:
5 units
Step-by-step explanation:
Since The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3 the points are
P (4 , 0) and Q(0 , 3)
The formula to calculate distance between two points
[tex]PQ=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\PQ=\sqrt{(0-4)^2+(3-0)}\\PQ=\sqrt{(4)^2+(3)^2}\\PQ=\sqrt{16+9} \\PQ=\sqrt{25} \\PQ=5\ units\ \\[/tex]
IMPORTANT!
As we take the square root of 25 we get two values +5 and -5 we always take the positive value because distance can never be negative.
