The probability that the first card is an odd number and the second card is less than 4 is 3/20.
We have,
To calculate the probability, we need to determine the number of favorable outcomes (the desired outcomes) and the total number of possible outcomes.
Favorable outcomes:
The first card is an odd number and has a probability of 5/10 since there are 5 odd-numbered cards (1, 3, 5, 7, 9) out of a total of 10 cards.
The second card is less than 4 and also has a probability of 3/10 since there are 3 cards (1, 2, 3) less than 4 out of a total of 10 cards.
Total number of possible outcomes:
Since we replace the first card before selecting the second card, the total number of possible outcomes for each selection is still 10.
Now, to find the probability of both events happening, we multiply the probabilities of each event:
Probability = (Probability of the first card being odd) * (Probability of the second card being less than 4)
= (5/10) x (3/10)
= 15/100
= 3/20
Therefore,
The probability that the first card is an odd number and the second card is less than 4 is 3/20.

Answer:
B
Step-by-step explanation:
The simplest way to do this is to take every integer on there and divide it by 3.
8961/3 = 2987
5233/3 = 1744 1/3
10245/3 = 3415
-5469/3 = -1823
Because B does not produce an integer, that is your answer

Answer:
x=-79/4, y=-45/8. (-79/4, -45/8).
Step-by-step explanation:
-2x+4y=17
3x-10y=-3
---------------
3(-2x+4y)=3(17)
2(3x-10y)=2(-3)

How to determine the factors of the function represented by the graph?From the question, we have the following parameters that can be used in our computation:
The graph
From the graph, we can see that:
The graph intersects with the x-axis at x = -4 and x = 8
So, we have
x = -4 and x = 8
Set the equations to 0
So, we have
x + 4 = 0 and x - 8 = 0
This means that the factors of the function represented by the graph are (x + 4) and (x - 8)

Step-by-step explanation:
x + 15 +2x + 66 = 180
3x + 81 = 180
3x = 99
x = 99/3 = 33
plz mark my answer as brainlist plzzzz.
hope this will be helpful to you.
Answer:
The angles are 66, 66, and 48 degrees
The triangle is isosceles because 2 angles are equal, thus two leg lengths are equal
Step-by-step explanation:
the sum of all three angles in a triangle = 180 degrees
66 + 2x + (x+15) = 180
simplify
66 +3x + 15 = 180
reduce
81 + 3x = 180
subtract 81 from each side
81 - 81 + 3x = 180 - 81
3x = 99
divide both sides by 3
3x/3 = 99/3
x = 33

The cheerleading squad at Kensington High School had 18 members with the old coach. Now, with the new coach, there are 50% more members on the squad, how many members are on the squad now
Answer:
27 members
Step-by-step explanation:
So we have 18 members and we see a 50% increase in members.
So:
Now the squad is 150% of 18
We can set up a percent proportion
x/150=18/100
To solve, we do:
(150*18)/100 = x
27 = x
There is an easier way to do this with benchmark fractions.
We find 50% of 18 which is 9
And since it's a 50% increase, we add 9 to 18 and get 27

The length of a rectangle is three meters more than its width the perimeter of the rectangle is 74 meters what are the dimensions of the rectangle
Answer:
17 meters x 20 meters
Step-by-step explanation:
perimeter = 2 widths + 2 lengths
74 = 2W + 2L
L = W + 3
substitute for L
74 = 2W + 2(W + 3)
74 = 4W + 6
68 = 4W
W = 17 meters
L = 20 meters
Answer:
Step-by-step explanation:
Givens
Let the width = w
Then the Length = w + 3
Formula
P = 2L + 2W
P = 74
Solution
Substitute w + 3 for L
2(W + 3) + 2W = 74 Remove the brackets
2W + 6 + 2W = 74 Collect Like Terms
4w + 6 = 74 Subtract 6 from both sides
4w = 74 - 6
4w = 68 Divide by 4
w = 68/4
w = 17
L = w + 3
L = 17 + 3
L = 20
Check
P = 40 + 34
P =74
