The probability of spinning an even number and flipping heads is..
Answer: 20% Chance
Step-by-step explanation:
Probability of flipping heads on a coin is 50% and this wheel landing on a even number is 40% you multiply .50 and .40 and you get .20.
Probability of spinning an even number and flipping heads P(A∩B) = (2 / 10).
What is probability?
" Probability is a mathematical expression which represents ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability= (Number of favourable outcomes) / (Total number of outcomes)
For Independent Event
P(A∩B) = P(A)×P(B)
According to the question,
'A' represents the probability of spinning an even number
'B' represents the probability of flipping heads
Possible outcomes on spinner = { 1, 2, 3, 4, 5}
Favourable outcomes of spinning an even number = 2
Total number of outcomes = 5
Substitute the value in the formula we get,
P(A) = ( 2 / 5)
Possible outcomes of flipping a coin = { head , tail}
Total outcomes of flipping a coin =2
Favourable outcomes flipping heads = 1
P(B) = (1 / 2)
Probability of spinning an even number and flipping heads P(A∩B)
A and B are independent events
Substitute the value of P(A) and P(B) in the formula we get,
P(A∩B) = ( 2/ 5)×(1/2)
= 2 /10
Hence, probability of spinning an even number and flipping heads P(A∩B) = (2 / 10).

What’s is the answer?
Answer:
m^8
Step-by-step explanation:
The number of tiles on the wall is [tex]m^{8}[/tex].
What is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
Given:
number of rows = m³
number of columns = [tex]m^{5}[/tex]
Now, we have to find the number of tiles in a wall

A chart labeled table B: effect of mass on temperature with initial temperature as 25 degrees Celsius, mass w is 1.0 kilograms and h is 500 m. The chart is 5 columns and 5 rows. The first column is labeled mass c in kilograms with entries 1.0, 3.0, 6.0, 9.0. The second column is labeled temperature final in degrees celcius with entries 26.17, 28.52, 32.03, 35.55. The third column is labeled change in temperature in degrees celcius with entries 1.17, 3.52, 7.03, 10.55. The fourth column is labeled gravitational potential energy in kilojoules with no entries. The last column is labeled delta H in kilojoules with no entries. Use the data provided to calculate the gravitational potential energy of each cylinder mass. Round your answers to the nearest tenth. 3 kg: kJ 6 kg: kJ 9 kg: kJ
Answer:
3 kg= 14.7
6 kg= 29.4
9 kg= 44.1
Step-by-step explanation:
The gravitational potential energy of the cylinders as follows:
3 kg: 14.7 kJ, 6 kg: 29.4 kJ, and 9 kg: 44.1 kJ
What is the GPE?GPE is gravitational potential energy, mass is the mass of the object in kilograms, gravity is the acceleration due to gravity in meters per second squared (usually taken to be 9.8 m/s²), and height is the height of the object above the reference point in meters.
To calculate the gravitational potential energy (GPE) of an object, you need to know its mass, the acceleration due to gravity, and its height above a reference point. You can use the formula:
GPE = mass × gravity × height
In this case, the mass of each cylinder is given in the first column of the chart, and the height of the cylinders is 500 meters. However, the acceleration due to gravity is not given in the chart. We can assume that it is 9.8 m/s², but if you have a different value, you should use that instead.
Using these values, we can calculate the gravitational potential energy of the 3-kilogram cylinder as follows:
GPE = 3 kg × 9.8 m/s² × 500 m = 14700 kg m/s²
Converting this to kilojoules gives us:
GPE = 14700 kgm/s² × (1 J/1 kgm/s²) = 14700 J
Converting this to kilojoules (kJ) gives us:
GPE = 14700 J / 1000 J/kJ = 14.7 kJ
Therefore, the gravitational potential energy of the 3-kilogram cylinder is 14.7 kJ.
You can use the same process to calculate the gravitational potential energy of the 6-kilogram is 29.4 kJ and the 9-kilogram cylinders is 44.1 kJ.

Using a compass, draw one arc with point M at the center and point N intersecting it as the first step in the typical construction of the perpendicular bisector of MN. Option C is correct.
What are perpendicular bisectors?Lines that cut through the middle of each side of a triangle and are perpendicular to the specified side are known as the perpendicular bisectors of the triangle.
The standard construction of the perpendicular bisector of MN will be,
Step 1: Sketch a line segment with any appropriate length, XY.
Step 2: Using a compass, draw arcs above and below the line segment, with X serving as the center and XY's width greater than 50%.
Step 3: Carry out Step 2 but use Y as the center. Step 4: Write "P" and "Q" next to the junction points.
Thus, using a compass, draw one arc with point M at the center and point N intersecting it as the first step in the typical construction of the perpendicular bisector of MN. Option C is correct.

Step-by-step explanation:
15% deduction from the initial price(100%) will have us remaining with 85%

85% = 85% x 670
100%
= $569.50
Complete the square:
x^2 +6x +c
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
So c= -9
The completed square form of the original expression is (x+3)² - 9 and the value of c is -9.
How to compute the perfect square?To compute the square, you need to add and subtract a number inside the parentheses such that the resulting expression is a perfect square trinomial.
To determine the square of half of the coefficient of the x term, which is 3 in this case.
The square of 3 is 9, so you need to add and subtract 9 inside the parentheses to complete the square. The resulting expression will be:
(x+3)² + c
To find the value of c, you need to compare this expression to the original expression: x² + 6x + c.
The x² and (x+3)² terms are equal, so you can set them equal to each other and solve for c:
x² = (x+3)² + c
x² - (x+3)² =c
(x-x-3)(x+x+3) = c
(-3)(3) = c
-9 = c
Therefore, c = -9.

What is the rate of change of the function y= -7?
Answer:
Zero
Step-by-step explanation:
Average rate of change can also be called as gradient or change in the respective variable , in this case we need the average rate of change of y which has the function y = -7
Since this is a linear function and if we draw the graph of y = -7 the graph would be parallel to the x-axis, and any line parallel to the x-axis has slope of zero , hence the average rate of change of the function y = -7 is zero
