What do you mean by GPS?Even though it appears complex, 3-dimensional trilateration is a straightforward mathematical process that underlies GPS. It's critical to have a fundamental understanding of 2-D Trilateration, which is necessary to completely comprehend 3-D Trilateration. Similar principles apply to three-dimensional trilateration, however, spheres rather than circles are used. Here is how the Global Positioning System uses 3-D trilateration to pinpoint an object's precise location. When the first satellite sends a signal, the GPS receiver measures the distance between the two. Say the distance between the receiver and the satellite is 20 000 miles. This implies that the receiver might be located anywhere on the 20 000 km diameter green sphere's surface and in any direction.

your bedroom sock drawer contains 4 green socks and 6 yellow socks that are mixed together. the light in your room is broken so you must select your socks in the dark. what is the probability you will select two socks of the same color on your first try?
Answers
The probability of selecting two socks of same color is 0.96.
According to the given question.
Total number of green socks = 4
Total number of yellow socks = 6
So, the total number of socks in a drawer = 4 + 6 = 10
Since as we know that, the probability of an event is computed as: P(E) = Number of favourable outcome /Total number of outcomes. Hence, the probability is the possibility of the occurrence of a random event.
So, the probability of selecting a green scoks = 4/10 = 2/5
And the probability of selecting a yellow socks = 6/10 = 3/5
Therefore, the probability of selecting two socks of same color
= probability of selecting both the green socks or probability of selecting both the yellow socks
= [( 2/5) + (2/5)] × [(3/5)+(3/5)]
= (4/5) × (6/5)
= 24/25
= 0.96
Hence, the probability of selecting two socks of same color is 0.96.

Lynden's first two, 100-meter-dash times are 13.075 seconds and 12.55 seconds. what are her mean (average) time? round your answer to the thousandths place.
Answers
The average time of Lynden's first two, 100-meter-dash is 12.813 seconds.
We are given the 100-meter-dash times of Lynden in first two races. So, the average time for first two races will be calculated using the formula -
Average = sum of all observations ÷ total number of observations
Sum of all observations here will be the sum of time of race.
Sum of observations = 13.075 + 12.55
Performing addition
Sum of observations = 25.625 seconds
Number of observations is the number of races whose time is taken in calculation.
Number of observations = 2
Keep the values in formula to find the average time.
Average time = 25.625 ÷ 2
Average time = 12.8125 seconds.

What is the student error in the multiplication below?
Multiply the ones: 957 times 23 = 2871. Above the 9 in 957 is 1, above the 5 in 957 is 2.
Multiply the tens: 957 times 23 = 2871. 2871 + 1914 = blank. Above the 9 in 957 is 1, above the 5 in 957 is 1.
Answers
Answer:
When multiplying the tens, the student didn't use the 0 place holder for the ones place.
Step-by-step explanation:
When using or doing long multiplication the answer was correct (2871) BUT before multiplying the tens, a zero should be placed in the ones place of the results. So, the tens should be 19140
2871+19140=22011
Answer: 1) When multiplying the ones, the student did not carry over a ten to the next place in the first multiplication.
2) When multiplying the ones, the student should have calculated 3 times 2 plus 5 as 11 and placed a 1 in the tens place.
3) When multiplying the tens, the student did not use the 0 place holder for the ones place.
4) When multiplying the tens, the student should have calculated 2 times 1 plus 9 as 11 and used a 1 should in the hundreds place.
Answer:
The correct option is;
4) When multiplying the tens, the student did not use the 0 place holder for the ones place
Step-by-step explanation:
Here we have when doing long multiplication, the student correctly multiplies the ones as 2871, however, before commencing multiplication of the tens, a 0 should be placed in the ones place of the result as a place holder such that the outcome of the multiplication of the tens should be;
19140
Hence, the correct result should be 2871 + 19140 = 22011
The correct option is therefore, that "When multiplying the tens, the student did not use the 0 place holder for the ones place."

In the given question,
Sine rule will be used to get the unknown side of the triangle.
According to the rule;

Given w = 3 in, ∠W=23° and ∠U=73°, substitute into the equation above to get u we have;
we can write the eq. as

What are the measures of missing angles of a geometric system?
In this problem we find a geometric system generated by three lines no collinear to each other, which generate the triangle DEF. In accordance with the Euclidean geometry, the sum of the measures of internal angles in a triangle equals 180°:
m ∠ FDE + m ∠ DEF + m ∠ DFE = 180° (1)
If m ∠ FDE = 80° and m ∠ DEF = 45°, then the measure of the angle DFE is:
m ∠ DFE = 55°
Finally, we find the values of the angles q, r and s by definition of supplementary angles:
q = 180° - 80°
q = 100°
r = 180° - 45°
r = 135°

two third of a number minus 5 gives 11
what is the number?
Answers
Answer: n=24
Step-by-step explanation:
n=number
2/3 * n - 5=11
2n/3=16
2n=48
n=24
2/3n (otherwise written as 2/3 • n) - 5 = 11
Any time there is a fraction of a number, that signifies for multiplication.
Let’s eliminate 5 by adding it to both sides of the equation:
2/3n - 5 + 5 = 11 + 5
2/3n = 16
Now we know that 2/3 of a number gives us 16. Now, let’s divide both of our numbers by 2/3:
• 2/3 divided by 2/3 gives us 1
• 16 divided by 2/3 gives us 24
Hence, 2/3 of 24 gives us 16.
n = 24
Let’s plug 24 into our original equation now:
2/3(24) - 5 = 11
16 - 5 = 11
Because this equation is true, we have solved for n. Our number is 24.

Answers
Answer:

Step-by-step explanation:
I = interest
p = principle
r = rate
t = time
I = prt Plug in what you know and solve for p
360 = p (.06)(8)
360 =p.48 Divide both sides by .48
750 = p
The principal is deposited in the account is $750.
Given that, rate of interest =6%, time period = 8 years and simple interest = $360.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.
Now, 360 = (P×6×8)/100
⇒ 360 = 48P/100
⇒ 48P = 36000
⇒ P = 36000/48
⇒ P = $750

The perimeter of the polygon will be 20 units and the area will be 21 square units.
From the given vertices a rectangle will be formed. A rectangle is a closed figure in which each interior angle is a right angle. The Perimeter of the rectangle can be given by formula 2(l + b) and the area is given by l×b where l is the length and b is breadth of rectangle. Now from the given points the dimensions of rectangle will follow the order W (5, -1), X (5, 6), Z (2, 6) and Y (2, -1).
The length of the rectangle is given by l = √ (6 + 1) ² + (5 - 5) ²
l = √49
l = 7 units
The breadth of the rectangle is given by b = √ (6 - 6) ² + (2 - 5) ²
b = √9
b = 3 units
Now, the perimeter of rectangle = 2 (l + b)
P = 2(7 + 3)
