Answer:
500m
Step-by-step explanation:
Given data
Frequency= 600,000 Hz
Speed= 300,000,000 m/s
We know that the formula for speed is
v=fλ
substitute
300,000,000=600,000λ
λ=300,000,000/600,000
λ=500 m
Hence the wave length is 500m
An angle whose measure is -405° is in
standard position. In what quadrant
does the terminal side of the angle fall?
Quadrant 1
Quadrant II
Quadrant III
Quadrant IV
Answer:
Quadrant IV
Step-by-step explanation:
Given
[tex]\theta = -405^\circ[/tex]
Required
The quadrant of the terminal side
To do this, we simply rotate the given angle in a clockwise direction.
A complete rotation is [tex]-360^\circ[/tex]
So, we have:
[tex]\theta = -405^\circ[/tex]
[tex]\theta = -360^\circ -45^\circ[/tex]
Remove the complete rotation
[tex]\theta = -45^\circ[/tex]
When [tex]45^\circ[/tex] is rotated in the clockwise direction, it stops at the 4th quadrant.
Hence, the terminal side falls in the quadrant IV
3456 cubic inches to cubic ft
The lesson is Multiple unit multipliers.
Answer:
Step-by-step explanation:
1 cubic foot is 12 * 12 * 12 cubic inches.
1 cubic foot = 1728 cubic inches.
1 cubic foot = 1728 cubic inches
x cubic feet = 3456 Cross multiply
1728 x = 3456 * 1 Divide by 1728
x = 3456/1728
x = 2 cubic feet.
The other way to do this is
3456 cu inches [1 cubic Foot/1728 cubic inches] note that the units cancel and you are left with 1 division problem.
The question still comes to 2.

Enter the equation of the circle with the given center and radius.
Center: (0, 5); radius: 5
The equation of the circle is
Answer:
x^2+(y-5)^2=25
Step-by-step explanation:
since you have a 5 in the y thats why the 5 ends up where it does. Then the radius is squared which is why you end up with that in this
CB is tangent to ⊙A at point C. Find the radius.
Circle A is shown. Line segment A C is a radii. Line segment B C is a tangent and it intersects with the circle at point C. A line is drawn from point B to point A and a point is drawn where the line intersects with the circle. The length of the radius is r, the length of C B is 8, and the length of B to the circle is 5.
Answer:
The length of the radius is 3.9 units
Step-by-step explanation:
From the details of the circle given, the circle is constructed with MS Visio and attached here;
From the drawing, we have;
The legs of the right triangle ABC = AC and CB
The given length of the leg CB = 8 units
The length from B to the circle on the hypotenuse side = 5 units
The length of the radius, AB = r
By Pythagoras's theorem, we have;
AB² = AB² + CB²
AB = r + 5 By segment addition postulate
Therefore;
(r + 5)² = r² + 8²
∴ (r + 5)² - (r² + 8²) = 0
r² + 10·r + 25 - r² - 8² = 0
10·r - 39 = 0
r = 39/10 = 3.9
The radius, r = 3.9 units long.
Answer:
39/10

Find the Mean, Median, and Mode
mean is the average and can be calculated by adding the scores and then dividing by the total number of scores.
for this take the total number of childrena and divide by the number of families which should give 3.5.
median is the middle number when the scores are put in order.
an easy way to find it from this data set is to just add the number of families from top down and bottom up and seeing where they meet which should be 3.
mode is the number that occurs the most in a data set.
for this data set it would be where the greatest number for number of families is which is 3 as there is 82 families.

The function g(x) = 3 |x| is a transformation of the absolute value parent
function. Which graph shows g(x)?
Using translation concepts, the graph that shows the function g(x) = 3|x| is graph B.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
Function g(x) = 3|x| is a vertical stretch of 3 units of function f(x) = |x|, that is, they keep the same vertex at (0,0), just graph g is stretched, passing at (1,3) instead of (1,1) for example, hence graph B is correct.

About 130000 high school students took the AP exam in 2010 .the free response section of the exam consisted of five open ended problems and an investigative task each free
Complete question is;
About 130,000 high school students took the AP Statistics exam in 2010. The free-response section of the exam consisted of five open-ended problems and an investigative task. Each free-response question is scored on a 0 to 4 scale (with 4 being the best). For one of the problems, a random sample of 30 student papers yielded the scores that are graphed in the dot plot attached. The mean score for this sample is x¯ = 1.267 and the standard deviation is s = 1.230.
(a) Find and interpret the standard error of the mean.
(b) Construct and interpret a 99% confidence interval to estimate the mean score on this question. Use the four-step process.
Answer:
A) SOE = 0.225
The interpretation of this is that: if a sample size of 30 was taken, the difference between a sample mean score and a population mean score will be an average of 0.225
B) CI = (0.648, 1.886)
The interpretation of this is that;
We are 99% confident that that interval (0.648, 1.886) captures the true mean score of the AP Statistics exam in 2010
Step-by-step explanation:
A) We are given;
sample mean; x¯ = 1.267
Sample standard deviation; s = 1.230
Sample size; n = 30
Formula for standard error of the mean is;
SOE = s/√n
SOE = 1.23/√30
SOE = 0.225
The interpretation of this is that: if a sample size of 30 was taken, the difference between a sample mean score and a population mean score will be an average of 0.225.
B) we have a sample size of n = 30.
Thus;
DF = 30 - 1 = 29
We want to do a 99% Confidence interval.
From the attached t-table, we can see that critical t-value for DF = 29 and CL of 99%, we have t = 2.756
Formula for CI is;
CI = x¯ ± t(s/√n)
CI = 1.267 ± 2.756(1.23/√30)
CI = 1.267 ± 0.619
CI = (0.648,1.886)
The interpretation of this is that;
We are 99% confident that that interval (0.648, 1.886) captures the true mean score of the AP Statistics exam in 2010.
