A date in March is chosen at random, then the spinner below is spun once. Find the probability of an odd number, and then blue. Use the counting principle to find the probability.
Answers
The probability of randomly selecting a date in March and spinning the spinner once, resulting in an odd number and then blue, is 1/6.
To find the probability of an odd number and then blue, we need to consider the number of favorable outcomes for each event and the total number of possible outcomes.
Probability of an odd number:
The spinner has 6 equally likely outcomes (numbers 1 to 6), and out of these, 3 are odd numbers (1, 3, and 5).
Therefore, the probability of getting an odd number is 3/6, which simplifies to 1/2.
Probability of blue:
The spinner has 6 equally likely outcomes, and out of these, 2 are blue. Therefore, the probability of getting blue is 2/6, which simplifies to 1/3.
To find the probability of both events occurring, we multiply the probabilities of each event:
Probability of an odd number and then blue [tex]= Probability $ of an odd number \times Probability $ of blue[/tex]
[tex]= (1/2) \times (1/3)[/tex]
= 1/6.

where x is the unknown number. To solve for x, we can divide both sides by 0.9 :
x = 110 ÷ 0.9
x = 122.22 (rounded to two decimal places)
So the unknown number is approximately 122.22.
To find 9% of that number, we can multiply 122.22 by 0.09 :
0.09 × 122.22 = 11.00 (rounded to two decimal places)
Therefore, 9% of the number is approximately 11.

Answers
The fraction expression 2 1/2 - 4 1/4 when evaluated is -1 3/4
Evaluating the fraction expressionTo solve 2 1/2 - 4 1/4, we need to convert the mixed numbers into improper fractions, then find a common denominator and subtract the two fractions.
First, we convert 2 1/2 and 4 1/4 into improper fractions:
2 1/2 = 5/2
4 1/4 = 17/4
Next, we find a common denominator. In this case, the smallest common denominator is 4:
5/2 = 10/4
17/4 = 17/4
Now we can subtract the fractions:
10/4 - 17/4 = -7/4
Finally, we can convert the resulting improper fraction back into a mixed number:
-7/4 = -1 3/4
Therefore, 2 1/2 - 4 1/4 = -1 3/4.

Answer:
m<H = 62.7°
Step-by-step explanation:
If we use an inverse sin, then that would be sin^-1(8/9) Because Sin equals opposite over adjacent.
Answer:
H = 62.7 degrees
Step-by-step explanation:
Because this is a right triangle, we can use one of the trigonometric functions to find angle H:
Notice that sides HJ and IJ are given. If we are trying to find angle H, then HJ is the hypotenuse (longest side) and IJ is the opposite (side opposite to the angle we are trying to find). Since the opposite and hypotenuse are both given, we can use a sine function to find the angle of H (keep in mind that sin(<) = opp/hyp):
sin(H) = 8/9
We have to use the inverse of sine (sin^-1 or arcsin) to find angle H and use a calculator to solve:
arcsin(8/9) = H = 62.7 degrees

The given trigonometric expression sin⁻¹(-3√(2)/2) in radians is approximately -2.2143 radians.
As we know that sin⁻¹(x) = -cos⁻¹(x) + π/2, which is the angle in the fourth quadrant whose cosine is 3sqrt(2)/2.
We have:
cos²θ + sin²θ = 1
Since sine is negative and cosine is positive, we know that:
sinθ = -sqrt(1 - cos²θ)
Substituting cosθ = 3√(2)/2, we get:
sinθ = -√(1 - (3√(2)/2)²) = -√(1 - 9/8) = -√(1/8) = -√(2)/2
Therefore, sin^(-1)(-3sqrt(2)/2) = -cos^(-1)(3sqrt(2)/2) + π/2.
Since cosine is positive in the fourth quadrant, we have:
cos⁻¹(3√(2)/2) = π/4
Substituting this value, we get:
sin⁻¹(-3√(2)/2) = -π/4 + π/2 = π/4
Therefore, sin⁻¹(-3√(2)/2) in radians is approximately -2.2143 radians.

tamara. Find the sum of two number cubes rolled at the same time. The chart below shows all possible sums from 36 possible combinations how many times should tamara expect the sum of two cubes to be equal to five if she rolls the cubes 180 times
Answers
Answer:
Step-by-step explanation:
There are 6 possible outcomes when rolling a single cube (1, 2, 3, 4, 5, or 6). When rolling two cubes, the possible sums range from 2 (1+1) to 12 (6+6). Using the chart provided, we can see that the sum of two cubes being equal to 5 only occurs once in the 36 possible combinations: when one cube shows a 1 and the other cube shows a 4.
To find the expected number of times this sum will occur if Tamara rolls the cubes 180 times, we need to multiply the probability of this event occurring on any given roll by the number of rolls. The probability of rolling a sum of 5 is 1/36, since there is only one way to get a sum of 5 out of the 36 possible combinations. Therefore, the expected number of times this sum will occur in 180 rolls is:
(1/36) x 180 = 5
So Tamara should expect to roll a sum of 5 about 5 times in 180 rolls of two cubes.

The length of wire used for the square is 0.25 meters and the length of wire used for the circle is 1 meter. To maximize the total area, the wire should be cut in half, with each piece having a length of 1 meter.
To minimize the total area of both figures and minimize the length of wire used, the wire should be cut in half, giving each piece a length of 1 meter.
For the square frame, we know that each side of the square is equal to the length of wire used to make it, so we can divide the 1 meter of wire in half to get 0.5 meters for each side of the square.
The perimeter of the circle is the length of wire used to make it, so we can use the remaining 1 meter of wire to find the radius of the circle:
2πr = 1
r = 1/(2π)
Using this radius, we can find the circumference of the circle and the length of wire used:
C = 2πr = 1 meter
Therefore, the length of wire used for the square is 0.5 meters and the length of wire used for the circle is 1 meter.
To maximize the total area, we need to cut the wire into two equal pieces, each with a length of 1 meter.
For the square frame, each side will have a length of 0.25 meters, which will give us a total area of 0.0625 square meters.
For the circle, the radius will be 1/(4π) meters, which will give us a circumference of 1/(2π) meters and a total area of π/(16) square meters.
Therefore, to maximize the total area, the wire should be cut in half, with each piece having a length of 1 meter.

what is statistic ?
A statistic is a numerical value or measure that is calculated from a sample of data, and is used to describe or make inferences about a population. Statistics are used in various fields, including business, economics, social sciences, and natural sciences, to analyze data
In the given question,
To test the claim that the percentage of residents who favor construction is more than 49%, we can use a one-sample z-test. The test statistic can be calculated as:
z = (p - P) / √(P * (1 - P) / n)
where:
p = the sample proportion (0.53)
P = the hypothesized population proportion under the null hypothesis (0.49)
n = the sample size (800)
Substituting the given values into the formula, we get:
z = (0.53 - 0.49) / √(0.49 * 0.51 / 800) ≈ 5.19
Rounding the test statistic to two decimal places, we get:
z ≈ 5.19

For example, 1% is 0.01
3.5% is 0.035
You can also move the decimal point back 2 places, but that's cringy.
So the problem says how much interest she will have to pay after one year, when the interest rate is 3.5%.
Therfore, we must multiply:
1500 by 3.5%

y = x² - 6x +9

Answers
The quadratic equation is solved and intersect at the points (4, 1) and (-1, 16)
Given data ,
To find the intersection points of the two functions, we can set them equal to each other and solve for x:
x² - 6x + 9 = -x² + 17
Bringing all the terms to one side:
2x² - 6x - 8 = 0
Dividing by 2:
x² - 3x - 4 = 0
We can factor this quadratic equation as:
(x - 4)(x + 1) = 0
So the solutions are:
x = 4 or x = -1
To find the corresponding values of y, we can substitute each value of x into either of the original equations
y = x² - 6x + 9
When x = 4:
y = 4² - 6(4) + 9 = 1
So one intersection point is (4, 1).
When x = -1:
y = (-1)² - 6(-1) + 9 = 16
So the other intersection point is (-1, 16).
Hence , the two functions intersect at the points (4, 1) and (-1, 16)

The electrical signal created by a piece of test equipment at a specific point in time is described by the function v inst(t)=12xsin(360x60x6.3+79). What is the maximum voltage produced by the system?
Answers
The maximum voltage produced by the system is 12 volts.
The function given is:
[tex]v_{inst}(t) = 12 * sin(360 * 60 * 6.3 + 79)[/tex]
To find the maximum voltage produced by the system, we need to determine the maximum value of the sine function within the given range.
Let's focus on the argument of the sine function: 360 * 60 * 6.3 + 79.
First, calculate the value of the argument:
360 * 60 * 6.3 + 79 = 136080 + 79 = 136159
Now, substitute this value back into the sine function:
sin(136159)
The sine function has a periodicity of 360 degrees or [tex]2\pi[/tex] radians. Therefore, we can subtract multiples of 360 degrees from the argument without changing the value of the sine function. Let's find the nearest multiple of 360 degrees to 136159:
136159 ÷ 360 [tex]^\sim_\sim[/tex] 378.22
Since the quotient is not an integer, we can conclude that subtracting multiples of 360 degrees will not bring us closer to a maximum or minimum value of the sine function.
Therefore, to find the maximum voltage, we need to evaluate sin(136159) directly. However, calculating the sine function of such a large number is not practical or necessary. The sine function oscillates between -1 and 1, and the maximum value it can reach is 1.
So, regardless of the specific value of sin(136159), the maximum voltage produced by the system will be:
Maximum voltage = 12 * 1 = 12 volts.

write the standard equation of a circle with its centre in the fourth quadrant tangent to x=7, y=-4 and x=17
Answers
Answer:
Step-by-step explanation:
To write the standard equation of a circle with its center in the fourth quadrant tangent to x=7, y=-4 and x=17, we can first find the center of the circle.
Since the center is in the fourth quadrant and tangent to x=7, y=-4 and x=17, the center must lie on the line x=12 (the midpoint between 7 and 17) and y=-4 (the point of tangency).
So the center of the circle is (12, -4).
Next, we need to find the radius of the circle. Since the circle is tangent to x=7 and x=17, the radius is the distance from the center to either x=7 or x=17.
The radius is thus 12 (the difference between 12 and 7) or 5 (the difference between 12 and 17).
So the standard equation of the circle is:
(x - 12)^2 + (y + 4)^2 = 25
