In a standard 52-card deck, half of the cards are red and half are black. The 52 cards are divided evenly into 4 suits: spades, hearts, diamonds, and clubs. Each suit has three face cards (jack, queen, king), and an ace. Each suit also has 9 cards numbered from 2 to 10. 7.
Dawn draws 1 card, replaces it, and draws another card. Is it more likely that she draws 2 red cards or 2 face cards?
Answer:
It is more likely she draws 2 red cards
Step-by-step explanation:
Given that:
Number of red d cards in deck = 26
Number of face cards = 4 * 3 = 12 face cards
If two cards are drawn with replacement ;
Probability = (required outcome / Total possible outcomes)
P(1st card red) = 26 /52) = 1/2
P(2nd card red) = 26 /52 = 1/2
P(1st card red) * P(2nd card red)
1/2 * 1/2 = 1/4 = 0.25
P(1st card face card) = 12/52 = 3/13
P(2nd card, face card) = 12/52 = 3/13
P(1st card face card) * P(2nd card face card)
3/13 * 3 /13 = 9/169 = 0.053
0.25 > 0.053
It is more likely she draws 2 red cards

what is the solution to this system of equations
A. (4,2)
B. (8,4)
C. (4,8)
D. (2,4)
Answer:
B. (8,4)
Step-by-step explanation:
To find the solution of the system, look at where the lines intersect. The intersecting point is (8,4). The solution to the system of equations is (8,4).
Answer:
B. (8,4)
Step-by-step explanation:
We want to find when these two equations are equal. The long way is to actually solve them using elimination or substitution of the equations. But, we can see an easier and clever way to solve them.
There is one specific time when equations are equal and that is when their lines intersect or cross, notice the graph and where they intersect. That specific coordinate where they intersect is your answer, (8, 4)!

A traffic engineer records a sample of the types of vehicles that cross a bridge. She counts 112 passenger cars, 18 light trucks, and 20 heavy trucks.
What is the APPROXIMATE probability that a random vehicle crossing the bridge is a passenger car?
Answer:
The approximate probability that a random vehicle is a passenger car is 74.67%
Step-by-step explanation:
Probability
The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.
We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:
[tex]\displaystyle p=\frac{112}{150}[/tex]
p = 0.7467
p = 74.67%
The approximate probability that a random vehicle is a passenger car is 74.67%

Find the midpoint of the line segment with end coordinates of:
(-3,-1) and (-4,2)
Answer:
(- 3.5, 0.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (- 4, 2) , then
midpoint = ( [tex]\frac{-3-4}{2}[/tex], [tex]\frac{-1+2}{2}[/tex] ) = ( [tex]\frac{-7}{2}[/tex], [tex]\frac{1}{2}[/tex] ) = (- 3.5, 0.5 )
The video streaming service that you want to use is represented with the equation below, where y represents the the total monthly cost of the service and x represents the number of videos you plan to stream each month:
y = $1.25x + $5.00
What is the total cost of the service for the month if you stream 30 videos?
Group of answer choices
$36.25
$151.25
$35.00
$42.50
Answer:
$42.50
Step-by-step explanation:
y = mx + b
x = how many videos you watched
y = 1.25(30) + 5.00 = 42.50
solve 3(y+4) = 24

Which value from the set {0,1,17,72} makes the equation n + 8 = 9 true?
answer: 1
step-by-step explanation: n + 8 = 9
therefore 9-8 = 1
The solution to the equation n+ 8 = 9 is 1 from the set {0,1,17,72} n = 1 satisfy the provided equation.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a linear function in terms of n:
n + 8 = 9
Subtract 8 both side:
n + 8 – 8 = 9 – 8
n = 1
From the set, we can see the element 1 is the solution to the given equation.
Thus, the solution to the equation n+ 8 = 9 is 1 from the set {0,1,17,72} n = 1 satisfy the provided equation.
