What is the measure of < L ? Need help
Answers
Looking at the image above, we can see that the two “legs” of the triangle both have a length of 7 units. Consequently, this triangle can be classified as an isosceles triangle. An isosceles triangle has two sides of equal length (in this case, KJ and KL) and two corresponding angles of equal measure (in this case, ∠J and ∠L).
∠J has a measure of 25 degrees. Consequently, with our knowledge of isosceles triangles, we can conclude that ∠L has a measure of 25 degrees as well.

Length contraction is the shortening of an object's measured length when it is moving relative to the observer's frame. The formula for length contraction is L = L0√(1 - (v^2/c^2)).
Explanation:Length contraction (L) is the shortening of the measured length of an object moving relative to the observer's frame. It occurs when an object is moving at a significant fraction of the speed of light. The formula for length contraction is L = L0√(1 - (v2/c2)), where L0 is the rest length of the object, v is its velocity, and c is the speed of light.

Suppose we want to form five digit numbers using the set of digits 0 1 2 3
Answers
Final answer:
The question pertains to creating five-digit numbers using the digits 0, 1, 2, and 3, with the restriction that the digit 0 cannot be used as the first digit. We consider the choices for each digit, leading to a total of 768 different combinations.
Explanation:
The student is asking about forming five-digit numbers with a set of digits 0, 1, 2, 3. To create five-digit numbers with these digits, we need to consider that each digit position can be one of these four digits. The fact that 0 is included as one of the possible digits is significant because it means 0 cannot be used as the first digit in a five-digit number as that would create a four-digit number.
Since there are restrictions on the use of 0 in the first position, the first position can only be filled with digits 1, 2, or 3, providing us with three choices for the first digit. The remaining four positions can be filled by any of the four digits (0, 1, 2, 3) without restriction. Thus, for each of the remaining four positions, we have four choices.
To calculate the total number of different five-digit numbers that can be formed, we would multiply the number of choices for each position, which yields 3 choices for the first digit and 4 choices for each of the remaining four digits. Therefore, the formula becomes 3 * 4 * 4 * 4 * 4, which equals 768 different five-digit numbers.
There are 768 five-digit numbers that can be formed using the digits {0, 1, 2, 3}.
To find out how many five-digit numbers can be formed using the set of digits {0, 1, 2, 3}, we can use the concept of permutations.
Since we want to form a five-digit number, we have 5 positions to fill. For each position, we have 4 choices: 0, 1, 2, or 3.
However, since the number cannot start with 0, we have only 3 choices for the first digit.
After choosing the first digit, the remaining four positions can be filled with any of the digits {0, 1, 2, 3}.
So, the total number of five-digit numbers that can be formed using the given set of digits is:
3 (choices for the first digit) × 4 (choices for each of the remaining four digits) × 4 (choices for each of the remaining four digits) × 4 (choices for each of the remaining four digits) × 4 (choices for each of the remaining four digits)
This simplifies to:
3 × 4^4 = 3 × 256 = 768
Therefore, there are 768 five-digit numbers that can be formed using the digits {0, 1, 2, 3}.
Question
Suppose we want to form five-digit numbers using the set of digits {0, 1, 2, 3}. For example, 30133 and 22301 are such numbers, but 03731 is not. How many such numbers are possible? There are no five-digit numbers formed by using the digits {0, 1, 2, 3}.

what is the equation of the axis of symmetry of a parabola if its x-intercepts are -3 and 7?
Answers
so what's the x-value halfway between -3 and 7? yeap, you guessed it, 2.
so the axis of symmetry for this vertical parabola will be at x = 2.
Based on the concept of the axis of symmetry, the equation of the axis of symmetry of the parabola is x = 2.
How the Equation of the axis of symmetry is determined?To find the equation of the axis of symmetry of a parabola given its x-intercepts, we can use the fact that the axis of symmetry is the vertical line that passes through the midpoint of the x-intercepts.
The midpoint formula is given by:
x-coordinate of midpoint = (x-intercept1 + x-intercept2) / 2
In this case, the x-intercepts are -3 and 7. Let's calculate the midpoint:
Midpoint = (-3 + 7) / 2
Midpoint = 4 / 2
Midpoint = 2
Therefore, the x-coordinate of the midpoint (and the equation of the axis of symmetry) is x = 2.
Hence, in this case, it is concluded that the equation of the axis of symmetry of the parabola is x = 2.

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 100 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 8 inches. How far did Chubby run? Give your answer in terms of pi. (prize is 99 points)
Answers
=======================================
Explanation:
The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter
We know that the diameter of the wheel is d = 8, so
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel
One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches
Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move

If the train that Megan is riding covers 80 miles in 2 hours, how fast is the train traveling?
Answers
To find this, you divide both 80 and 2 by 2 to find how many miles in a single hour the train travels. Thus giving you 40 miles in an hour (40 mph) as a ginal answer.
I hope this helps!
Final answer:
The average speed of the train Megan is traveling on is 40 miles per hour. It's obtained by dividing the total distance of 80 miles by the total time of 2 hours.
Explanation:
To find the average speed of the train that Megan is riding, which covers 80 miles in 2 hours, we will use the formula for average speed, which is total distance divided by total time. The train travels 40 miles one way and 40 miles back, totaling 80 miles.
Here is the step-by-step calculation:
Calculate the total distance the train travels: 40 miles one way + 40 miles back = 80 miles.
Calculate the total time of the journey: 2 hours.
Divide the total distance by the total time to find the average speed: 80 miles / 2 hours = 40 miles per hour.
This means the average speed of the train is 40 miles per hour.

b ≈ 26.2, C ≈ 22.3, A ≈ 121.7
Answers
B = 36°, a = 38, c = 17
using cosine rule:
b^2=a^2+c^2-2accosB
b^2=38^2+17^2-2*38*17cos36
b^2=697.7500
b=26.2
th missing angles will be evaluated using sine rule:
a/sin A=b/sin B
thus
38/sin A=26.2/sin 36
sin A=(38sin 36)/26.2
sin A=0.8525
A=58.49
since a is the longest side then A is the largest angle and it will be:
A=180-58.49=121.51
also:
c/sin C=b/sin B
17/sin C=26.2/sin 36
sin C=0.3814
C=22.42

If P(A or B)equals=0.60.6, P(A)equals=0.40.4, and P(A and B)equals=0.350.35, find P(B).
Answers
Answer:
P(B) = 0.55 .
Step-by-step explanation:
We are given that P(A or B) = 0.6 , P(A) = 0.4 , and P(A and B) = 0.35 .
As we know that;
P(A or B) = P(A) + P(B) - P(A and B)
0.6 = 0.4 + P(B) - 0.35
P(B) = 0.35 + 0.6 - 0.4 = 0.55
Therefore, P(B) = 0.55 .

Select all that apply. In a linear function: Δy = 0 Δx = 0 Δy = n Δx = n Δy = -n Δx = -n
Answers
Explanation:
1) Δy = 0
Means y is constant, which is also that the slope is zero.
The function is a horizontal line (paralell to the x-axis)
2) Δx = 0
Means x is constant, the slope is not defined (∞).
The function is a vertical line (parallel to the y-axis)
3) Δy = n
Means that the change in y is constant. So, only if the change in x is also constant the slope is constant and the function is linear.
This is because the slope is Δy / Δx.
4) Δx = n
Means the change in x is constant. So, only if Δy is constant it is a linear function, for the same reason explained above
5) Δy = -n and and 6) Δx = -n
Same reasoning of 3 and 4.

All options are correct except Δx = 0.

A random sample of 31 charge sales showed a sample standard deviation of $50. a 90% confidence interval estimate of the population standard deviation is
Answers
[tex] \sqrt{ \frac{(n-1)s^2}{\chi^2_{1- \frac{\alpha}{2} } }} \leq\sigma\leq\sqrt{ \frac{(n-1)s^2}{\chi^2_{\frac{\alpha}{2} } }}[/tex]
Given a sample size of 31 charge sales, the degree of freedom is 30 and for 90% confidence interval,
[tex]\chi^2_{1- \frac{\alpha}{2} }=43.773 \\ \\ \chi^2_{\frac{\alpha}{2} }=18.493[/tex]
Therefore, the 90% confidence interval for the standard deviation is given by
[tex]\sqrt{ \frac{(31-1)50^2}{43.773 }} \leq\sigma\leq\sqrt{ \frac{(31-1)50^2}{18.493 }} \\ \\ \Rightarrow\sqrt{ \frac{(30)2500}{43.773 }} \leq\sigma\leq\sqrt{ \frac{(30)2500}{18.493 }} \\ \\ \Rightarrow\sqrt{ \frac{75000}{43.773 }} \leq\sigma\leq\sqrt{ \frac{75000}{18.493 }} \\ \\ \Rightarrow \sqrt{1713.38} \leq\sigma\leq \sqrt{4055.59} \\ \\ \Rightarrow41.4\leq\sigma\leq63.7[/tex]
Final answer:
The 90% confidence interval estimate of the population standard deviation is (0.97, 274).
Explanation:
To estimate the population standard deviation with a 90% confidence interval, you can use the formula:
CI = [s * sqrt(n-1) / sqrt(chi-squared lower value), sqrt(chi-squared upper value))]
where s is the sample standard deviation, n is the sample size, and chi-squared lower and upper values are obtained from a chi-squared distribution table. For a 90% confidence interval, the chi-squared lower value is 0.05 and the chi-squared upper value is 0.95 for the given sample size of 31. Plugging in the values:
CI = [50 * sqrt(31-1) / sqrt(0.05), sqrt(0.95))] = [50 * sqrt(30) / sqrt(0.05), sqrt(0.95))] = [50*5.48, 0.97] = [274, 0.97]
Therefore, the 90% confidence interval estimate of the population standard deviation is (0.97, 274).
