Answer: 0.1630
Step-by-step explanation:
Number of quarters = 10
Number of dimes = 6
Number of nickels = 8
Total number = 10+6+8 = 24
Probability of choosing the first quarter will be: = Number of quarters/Total number of money
= 10/24 = 5/12
Since a quarter has been selected, the total number will reduce to 23 the next time a quarter is choosing and the number of quarters will now be 9. Therefore, the probability of choosing the second quarter will be: = 9/23
Therefore, the probability that two quarters are chosen random from the jar will be:
= 5/12 × 9/23
= 45/276
= 0.1630
can 5,7 and 13 make a triangle
Answer:
No
Step-by-step explanation:
5+7=12
12>13 X
13+5=18
18>13 YES
13+7=20
20>5 YES
If all equations were true, it would make a triangle, but since only 2 are true, it doesn't make a triangle.

is the relationship linear, exponential, or neither?
Answer:
the answer is exponential!
Step-by-step explanation:
the relation is linear.
What is a linear relation?A straight-line link between two variables is referred to statistically as a linear relationship (or linear association). Linear relationships can be represented graphically or mathematically as the equation y = mx + b. In daily life, linear relationships are pretty typical.
Given
Numbers have a common difference of 5 from each other.
So relation is linear.

10. RECREATION In a game of kickball, Rickie has to kick the
ball through a semicircular goal to score. If m XZ = 58 and
the m XY = 122, at what angle must Rickie kick the ball to
score? Explain.
Answer:
The angle Rick must kick the ball to score is an angle between the lines BX and BZY which is less than or equal to 32°
Step-by-step explanation:
The given measures of the of the angle formed by the tangent to the given circle at X and the secant passing through the circle at Z and Y are;
[tex]m\widehat{XZ} = 58^{\circ}[/tex]
[tex]m\widehat{XY} = 122^{\circ}[/tex]
The direction Rick must kick the ball to score is therefore, between the lines BX and BXY
The angle between the lines BX and BXY = ∠XBZ = ∠XBY
The goal is an angle between [tex]m\widehat{XY}[/tex]
Let 'θ' represent the angle Rick must kick the ball to score
Therefore the angle Rick must kick the ball to score is an angle less than or equal to ∠XBZ = ∠XBY
By the Angle Outside the Circle Theorem, we have;
The angle formed outside the circle = (1/2) × The difference of the arcs intercepted by the tangent and the secant
[tex]\therefore \angle XBZ = \dfrac{1}{2} \times \left (m\widehat{XY} -m\widehat{XZ} \right)[/tex]
We get;
∠XBZ = (1/2) × (122° - 58°) = 32°
The angle Rick must kick the ball to score, θ = ∠XBZ ≤ 32°

I dont understand mean or median. Can someone help?
Answer:
both of these are ways to kinda categorize numbers.
MEAN- you're finding the average. average and mean are synonymous. meaning they're the exact same. with the mean, all you have to do is add all the numbers up and then divide that by however many numbers you added up
lets say you need to find the mean of a domain and you're given this set of numbers:
{1,2,3,4,5,6,7}
the sum is 28. You divide it by 7 (bc thats how many numbers you added up) and you get your mean to be 4
The MEDIAN is going to be simpler than you may think. put all the numbers in numerical order, greatest to least or least to greatest. it doesn't matter.
Then find the number in the middle. Some people like crossing off the numbers on either end until you get to the center. So like marking off 1 then 7 then 2 then 6 etc.
The median is 4.
Step-by-step explanation:
Of course, I'm glad to help.
Mean is average. So for example, if I had the numbers 2,3,4, and 5 the mean would be 10.25.
The steps to getting mean are adding up all your numbers then dividing by the number of equalities you have.
Median is the middle number in your group. For example, if I had numbers 2, 3, 4, 5, and 6. The median would be 4 because that the number in the middle.
But when you have an even amount of numbers (for example 2,3,4,5) you'd add up the ones in the middle (3 and 4) then divide them by 2 (3+4=7/2). In this case, the median would be 3.5.

The length the height of a rectangular prism are 12 feet and 9 feet respectively. Determine the width of the rectangular prism whose surface area is 258 square feet
Answer:
Width = x feet = 1 feet
Step-by-step explanation:
Surface area of a rectangular prism = 2(lw +lh + wh)
Length = 12 feet
Width = x feet
Height = 9 feet
Surface area = 258 square feet
Surface area of a rectangular prism = 2(lw +lh + wh)
258 = 2{(12*x) + (12*9) + (x*9)}
258 = 2(12x + 108 + 9x)
258 = 24x + 216 + 18x
258 - 216 = 24x + 18x
42 = 42x
x = 42/42
x = 1 feet
Width = x feet = 1 feet

Is
X 10 11 12
Y 18 18.6 19.2 proportional or non proportional
Given:
The table of values.
To find:
Whether the given table is a proportional or non proportional relation.
Solution:
If y is proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
[tex]\dfrac{y}{x}=k[/tex]
Where, k is the constant of proportionality.
Find the value of k for each ordered pairs in table. If the value of k is constant, then the relation is proportional.
The ordered pairs from the table are (10,18), (11, 18.6), (12,19.2). The values of k for each ordered pair is:
[tex]\dfrac{18}{10}=1.8[/tex]
[tex]\dfrac{18.6}{11}\approx 1.69[/tex]
[tex]\dfrac{19.2}{12}=1.6[/tex]
Since the value of k is not constant, therefore the given table represents a non proportional relationship.

Answer:
300 in.³
Step-by-step explanation:
We find the volume of 1 prism and multiply it by 2.
V = BH
where V = volume of prism, B = area of the base of the prism, H = height of the prism
V = ½bh × H
V = ½(5 in.)(6 in.) × 10 in.
V = 150 in.³
That is the volume of one triangular prism. Now we multiply it by 2.
volume = 2 × 150 in.³ = 300 in.³

What ideas do you have about what makes Anchorage, Alaska, cooler than Christchurch, New Zealand?
Answer:
You can explore a variety of things in Alaska. There are so many activities you could do such as visiting museums and hiking and tons more. The thing about this is that it is out in the wilderness which makes it more exciting and cooler to see nature more than it does in new zealand. The climate can be pretty chilly in Alaska but it is way much fun to see tons of glaciers. New zealand has eathquakes frequently whilst Alaska doesn't.
