a piggy bank contains 2 quarters , 3 dimes , 4 nickels , and 5 pennies. one coin is removed at random. what is the probability that the coin is a dime? what's the probability that the coin is a nickel?
Answer:
Hope this helps
Step-by-step explanation:
Probability of dime:
There are 14 coins.
3 of which are dimes
you would put it over 14: 3/14 and cross multiply it with x/100
then you would get 300 and 14x
Divide 300 by 14 approximately 21. 4%
Probability of nickel:
There are 14 coins.
same thing as the top one,
you put 4/14 and times it by x/100
you get 400 and 14x
divide 400 by 14
and get about 27.7%
Hope this helps!
Sorry if wrong! :)

2650 10 260 words per minute
Which student reads at a fastest rate? In your final answer, include all necessary calculations.
Answer:
here is the ANSWER-Connie : 1min = 200 words
Felicia : 1min = 260 words
Stew : 1 min = 265 words (8min = 2120 words, and 7min = 1855 words, so you minus 2120 - 1855 = 265 words)

the experimental probability of spinning a number less than 3 is...?
Answer:
28%
Step-by-step explanation:
8 + 6 = 14
the total of the numbers spun is 50
so as a percentage it would be 28%
The experimental probability of spinning a number less than 3 is 0.28
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
here, we have,
To find the experimental probability of spinning a number less than 3, we need to add up the number of times we spun 1 or 2 (since these are the numbers less than 3) and divide by the total number of spins:
Number spun Times spun
1 8
2 6
3 9
4 11
5 9
6 7
Total: 50
Number of spins that resulted in a number less than 3: 8 + 6 = 14
Experimental probability of spinning a number less than 3: 14/50 = 0.28 or 28%
So the experimental probability of spinning a number less than 3 is 0.28 or 28%.

What is the approximate volume of the cone?
Use 3.14 for π.
1206 cm³
2170 cm³
3260 cm³
6510 cm³
Answer:
1206 cm³
Step-by-step explanation:
The formula for the volume of a cone is [tex]\pi r^{2} (\frac{h}{3} )[/tex] with h being the height of the cone. in this case 8cm
So, the volume will be 3.14x12^2(8/3)

calculate the surface of each 3D shape below then from the right, drag and drop the correct surface area calculation into the box below with the corresponding shape
Answer:
1. 1,314 in^2
2. 465in^2
3. 464in^2
4. 157.5in^2
Step-by-step explanation:
The steps to this is easy. since they give you the nets.
1. The formula for finding the surface area of a cuboid is 2(LB + LH + BH). Where L is the length, B is the breadth or width and H is the height. In this question, the length is 26 in, width is 17 in and height is 5 in. Therefore, the equation will be 2(26in(17in) + 26in(5in) + 17in(5in)). From there its simple application of the rules of BODMAS.
2. Since the net of this pyramid is given, the surface area is simply the area of the base plus the areas of all the individual triangular faces.
3.The net has been given so we apply the same method here. we find the area of the rectangular and the triangular faces and sum them up. ( For this question, it seems that there isnt any possible answer that matches mine. So I apologise for the inconvenience.)
4.We find the area of just one of the triangular faces and multiply it by 4 to get our answer.

Answer:
Lake Eyre is higher by 242 meters.
Step-by-step explanation:
Jericho = -258
Lake Eyre = -16
-258 - (-16) = -242
Lake Eyre is 242 meters higher than Jericho below sea level.

The set of points (–3, 7), (0, –3) and (6, 1) are plotted in the coordinate plane. Which of the following statements is true about the graph of these points? A. They do not represent a linear function. B. The slopes of the lines between each pair of points are equal. C. The first coordinate of each ordered pair is always less than the second coordinate. D. The coordinates of the ordered pairs satisfy the equation .
Answer:
X coordinate
Y coordinate
rectangle
Step-by-step explanation:
The statements is true about the graph of these points is
The coordinates of the ordered pairs satisfy the equation .
What is slope?The slope of a line is the measure of the steepness and the direction of the line. The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.
Slope = m = tan θ = (y2 - y1)/(x2 - x1)
where, m is the slope, and θ is the angle made by the line with the positive x-axis.
According to the question
The set of points (–3, 7), (0, –3) and (6, 1) are plotted in the coordinate plane.
Conditions which are true in options for set of points .
a> They do not represent a linear function.
A linear function is defined as a function that has either one or two variables without exponents.
This statement is false they do represent the linear function.
b>The slopes of the lines between each pair of points are equal.
slopes between (–3, 7), (0, –3)
Slope = (y2 - y1)/(x2 - x1)
Slope = (7 - (-3))/( (-3))
Slope = [tex]\frac{-10}{3}[/tex]
slopes between (0, –3) and (6, 1)
Slope = (y2 - y1)/(x2 - x1)
Slope = (1 - (-3))/(6- (0))
Slope = [tex]\frac{2}{3}[/tex]
Hence, this statement is false .
c>The first coordinate of each ordered pair is always less than the second coordinate.
This statement is false as in both ordered pair (0, –3) and (6, 1) first coordinate is bigger than second
d>The coordinates of the ordered pairs satisfy the equation .
This is true as ordered pairs satisfy the equation .
y = mx +c
Hence, the statements is true about the graph of these points is
The coordinates of the ordered pairs satisfy the equation .
