at random. What is the probability that the key that is drawn is silver or copper?
Answers
Answer:
D. 24/35
Step-by-step explanation:
Step one:
Given
Sample space
14 silver keys,
7 black keys,
10 copper keys, and
4 painted keys of various colors
Sample size= 14+7+10+4= 35
in probability "or" means that we need to add events.
Hence, the probability that the key that is drawn is silver
= 14/35
the probability that the key that is drawn is copper
=10/35
Step two:
The probability that the key that is drawn is silver or copper
14/35+10/35
=14+10/35

What are the area and perimeter of square TUVW?
Area=
Perimeter=
Answers
Answer:
Area: 196
Perimeter: 56
Step-by-step explanation:
1. Pick a side for both length and height and count the distance between the two coordinates (for example VU and UT)
VU = 14
UT= 14
Also important to note here that you don't even need to count the distance for both because since it's a square, all the sides are the same. Only did this to make it easier to understand the next step.
2. Since it's a square, as I said before, all sides are the same. So, you can go ahead and mark WT and VW as 14 as well.
3. To get the area, use the formula base times height.
14 x 14 = 196
4. For perimeter, simply add up all the sides (or multiply 14 by 4 since all are the same)
14+14+14+14=56

y=2/3x-5
Step-by-step explanation:
First, let's put this equation into slope-intercept form.
2x-3y=24
-3y=-2x+24
y=2/3x-8
For two lines to be parallel, they must have the same slope. Therefore our slope is 2/3.
Now, we must find b. To do that we can plug the y and the x in.
-7=2/3(-3)+b
-7=-2+b
-5=b
y=2/3x-5
Answer:
y = [tex]\frac{2}{3}[/tex]x - 5
Step-by-step explanation:
Points: (-3, -7)
Equation: 2x - 3y = 24
2x - 3y = 24
-3y = -2x + 24
y = [tex]\frac{2}{3}[/tex]x - 8
y = [tex]\frac{2}{3}[/tex]x + b
-7 = [tex]\frac{2}{3}[/tex] ( -3 ) + b
-7 = -2 + b
b = -5
y = [tex]\frac{2}{3}[/tex]x - 5

.25x + .05y = 1.15
25x + 5y = 115
-25x - 25y = -275
-20y = -160
y = 8 nickels
x + 8= 11
x = 3 quarters

WILL GIVE BRAINLIEST ! A marble is picked at random.Without putting the first marble back,a second marble is picked at random find the probability that the fist marble picked is green and the second marble is picked red write your result as a percentage
Answers
Step-by-step explanation:
The percentage is 1/2 * 2/5 = 1/5 = 20%.
The probability that the first marble picked is green, and the second marble is picked red is 20%
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Given that, there are six marbles in total, 3 are green, 2 are red and one is brown,
we need to find the probability that the first marble picked is green, and the second marble is picked red,
So, P(E) = favorable outcome / total outcome
Therefore, the probability that the first marble picked is green, and the second marble is picked red = 3/6 x 2/5 = 6/30 = 1/5 = 20%
Hence, the probability that the first marble picked is green, and the second marble is picked red is 20%
