find the value of x in the following figure
Answers
Answer:
x = 172
Step-by-step explanation:
A circle is 360 degrees
The angles will add to 360 degrees
x/2 + 59 + x/4 + x = 360
Subtract 59 from each side
x/2 + x/4 +x +59-59 = 360 -59
x/2+x/4+x = 301
Combine like terms
2x/4 +x/4 +4x/4 = 301
7/4x = 301
Multiply each side by 4/7 to isolate x
4/7 * 7/4 x = 301 *4/7
x =172

What is the difference between the theoretical and experimental probabilities of getting heads?
A. 0.5
B. 0.0
C. 0.3
D. 0.1
Answers
Answer:
c 0.3
Step-by-step explanation:
there is are 50/50 chance when a coin is flipped but according to the data it is 80/20 so if to take 80-50=30 so it is a 0.3 change in probability.
The difference between the theoretical and experimental probabilities of getting heads is 0.3.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
A fair, unbiased coin was flipped 10 times.
The result is shown in the table.
Total number of outcomes = 10
For the experimental probability,
Number of heads = 2
Experimental Probability of getting heads, E = 2/10 = 0.2
For the theoretical probability,
Theoretical Probability of getting heads, T = 1/2 = 0.5
Difference = 0.5 - 0.2 = 0.3
Hence the difference is 0.3.

If 4, x, y, 108 are the consecutive terms of a G.P., find x and y.
Answers
Given:
4, x, y, 108 are the consecutive terms of a G.P.
To find:
The x and y.
Solution:
The nth term of a G.P. is:
[tex]a_n=ar^{n-1}[/tex]
Where, a is the first term and r is the common ratio.
Let us consider 4, x, y, 108 are the first 4 terms of the G.P. Here 4 is the first term of the given G.P.
Suppose r the common ratio, then 4th term of the given G.P. is:
[tex]a_4=4(r)^{4-1}[/tex]
[tex]a_4=4(r)^{3}[/tex]
The 4th term of the G.P. is 108.
[tex]4(r)^{3}=108[/tex]
[tex]r^{3}=\dfrac{108}{4}[/tex]
[tex]r^{3}=27[/tex]
[tex]r^{3}=3^3[/tex]
On comparing both sides, we get
[tex]r=3[/tex]
The common ratio is 3.
The second term of the given G.P. is:
[tex]x=4r[/tex]
[tex]x=4(3)[/tex]
[tex]x=12[/tex]
The third term of the given G.P. is:
[tex]y=xr[/tex]
[tex]y=12(3)[/tex]
[tex]y=36[/tex]
Therefore, the value x is 12 and the value of y is 36.

On the grid, draw graphs of y=x+2 and x+y=3
Answers
Answer:
The image shows the answer and below I will explain more about it.
Step-by-step explanation:
To draw a line all you need is two points on the graph, and people mainly use the coordinates of the y and x intercepts to draw it (when x=0 and when y=0)
so for these questions all we do is:
y=0+2 (we are putting x=0 into the equation)
y=2, x=0 so this is the first of our set of coords:
0=x+2
x=-2 y=0 (we are putting y=0 into the equation)
so all you do is plot these in and draw a line which passes between both,
now just repeat for the other one :)
Mean of 8, 3,5
and mean of 44,89,23
Answers
Answer:
mean of 8,3,5 = 5.333 or 16/3
mean of 44,89,23 = 52
Step-by-step explanation:
Answers and step-by-step explanations:
To find the mean, first, we are going to add all of the numbers, and divide by how many numbers there were. The first data set is:
8, 3, 5
Add them all up:
8 + 3 + 5 = 16
Then, since there were three numbers, we divide 16 by 3.
16/3 = 5.33
Therefore, the mean of 8, 3 and 5 is around 5.33.
The second data set is:
44, 89, 23
Add them up:
44 + 89 + 23 = 156
Then, divide it by how many numbers there were, which is 3.
156/3 = 52
Therefore, the mean of 44, 89 and 23 is 52. Hope this helps!

a. Probability Sampling
b. Convenience Sampling
c. Voluntary Sampling
d. Stratified Sampling
e. None of the above
Answers
Answer:
d. Stratified Sampling
Step-by-step explanation:
Stratified Sampling is a form of sampling in which the researcher selects a population sample based on a demographic factor or strata such as race or gender. From the different strata, a random sample is then made such that each group or subpopulation is represented in the final sample.
It should be noted that retaining the percentages while selecting a randomized sample is essential to stratified sampling.
Hence, in this case, when the researcher obtains a list of all enrolled freshmen, manipulates the list so that females appear twice as often as males, and then selects from this list, this is an example of stratified sampling

The answer will be 19/10 or 1 9/10
Step-by-step explanation:
Soo... let's simplify 1 2/5 first.
The simplified version of 1 2/5 is 7/5.
and we solve the equation!
since there are two negatives, turn it into a plus!
7/5 + 1/2
5 x 2 = 10 2 x 5 = 10
7 x 2 = 14 1 x 5 = 5
so...
14/10 + 5/10 which will be 19/10, or 1 9/10
