The odds of winning the game is [tex]\frac{8}{13}[/tex].
What is probability?Probability is the measure of happening and non-happening of the outcomes of a random experiment.
What is the sum of probabilities?The sum of all the probabilities of all the elementary events of an experiment is always 1.
According to the given question.
We have
The probability of losing the game is [tex]\frac{5}{13}[/tex]
Since, we know that the sum of all the probabilities of all elementary events of an experiment is always 1.
Therefore,
Probability of winning the game + Probability of losing the game = 1
⇒ Probability of winning the game + [tex]\frac{5}{13} =1[/tex]
⇒ Probability of winning the game = [tex]1 - \frac{5}{13}[/tex]
⇒ Probability of winning the game = [tex]\frac{13-5}{13}[/tex]
⇒ Probability of winning the game = [tex]\frac{8}{13}[/tex]
Hence, the odds of winning the game is [tex]\frac{8}{13}[/tex].

The length of a rectangular garden is 22 feet longer than its width. If the area of the garden is 408 square feet, what are the dimensions of the garden?
Length=
Width=
Answers
Answer:
Length = 34 ft
Width = 22 ft
I know for SURE!
Pls mar branliest!!
Answer:
Length = 34
Width = 12
Step-by-step explanation:
Let the lenght of the garden be denoted by L, and let the width of the gardne be denoted by W.
The length of a rectangular garden is 22 feet longer than its width: L=W+22
The area of the garden is 408 square feet: A=LW=408
SubW+22 in for L in the equation LW=408 :
LW=408
(W+22)W=408
[tex]W^{2}[/tex]+22W-408=0
(W-12)(W+34)=0
So we have W=12 and W=-34. However, W can't be equal to -34 as width can't be negative. Therefore, the width of the garden is 12feet.
L=W+22=12+22=34. The length of the garden is 34feet.

Help, What is the volume of the concrete piece?
Answers
Answer:
72,000
Step-by-step explanation:

Volume is length x width x height.
I would split the figure into two different parts.
(In the picture I drew a line)
So no let’s find the volume of both shapes.
The fist one is 8 x 5 x 19
You get 19 as the height because the 9 and the 10 need to be added together to get the height of the shape.
8 x 5 = 45
45 x 19 = 855
Now let’s find the volume of shape #2
20 x 8 x 9
20 x 8 = 40
40 x 9 = 360
Now we have the volume of the shape split into two parts so we need to add them together.
855 + 360 = 1,215
I think that’s how you do it. I haven’t done this in a while
