A central angle of a circle measures 42 degrees. What else can be shown to measure 42 degrees?
Answers
Answer:
Vertically opposite angles
Step-by-step explanation:
Given
[tex]\theta = 42^\circ[/tex]
Required
What else can measure [tex]\theta = 42^\circ[/tex]
The question has missing options. So, I will give a general explanation.
Using the attached image as a point of reference.
Given that:
[tex]\theta = 42^\circ[/tex]
The value of b is calculated as:
[tex]b = \theta[/tex]
Because b and [tex]\theta[/tex] are vertically opposite angles
This gives:
[tex]b = 42^\circ[/tex]
So, one possible answer to the question is a vertically opposite angle

Answers
Answer:
JK, KI, IJ
Step-by-step explanation:
The smaller the angle opposite to the side, the smaller the length of the side. In this way, since 44° is less than 50°, JK is shorter than KI.
To find the third angle, and thus whether IJ is longer or shorter than the first two sides, subtract the sum of the other two angles from 180°.
∠K[tex]=180-(50+44)=180-94=86[/tex]
Thus, since 86° is greater than the other two angles, IJ is longer than the other two sides.
Therefore, from least to greatest, the side lengths of ΔIJK are ordered as JK, KI, IJ. QED

Flip a fair coin 5 times. Let random variable X = "number of heads."What is P(X = 1)?
Answers
Answer:
The probability is 1/32
Step-by-step explanation:
What the question asks here is that in a throw of a coin 5 times, what is the probability that we have the head being revealed once in the 5 throws
for a fair coin, we can only get a head or a tail
So the probability of getting a head equals that of getting a tail
Since total probability is 1; then the probability of each will be 1/2
So, we can now have the probability as follows;
1 head (1/2) and 4 tails (1/2 * 1/2 * 1/2 * 1/2)
1/2 * 1/2 * 1/2 * 1/2 * 1/2 = (1/2)^5 = 1/32

Statements are (underlined) and reasons are (bolded).
It is given that (<W) and (<Y) are both right angles, therefore, they must be congruent since they have the same angle measures.
<W = <Y definition of right angles
Moreover, it is given that (VX) and (ZX) are congruent.
VX = ZX given
Finally, it is given that (x) is the midpoint of (WY). Therefore, (WX) is congruent to (XY), and therefore, they are congruent.
WX = XY definition of midpoint
Thus, triangle (YWX) is congruent to (ZYX) by the following rule, side-angle-side, also known as (SAS).
YWX = ZYX SAS
When two sides and an angle are congruent between two or more triangles, then those triangles must be congruent.
Solve the equation sin^2x= 3 cos^2x.
The value of x that satisfies the equation if x lies in the second quadrant is what degrees?
The value of x that satisfies the equation if x lies in the third quadrant is what degrees?
Answers
Step-by-step explanation:
sin^2(x)= 3 cos^2(x)
Subtract sin^2(x) on both sides
0=3cos^2(x)-sin^2(x)
By Pythagorean Identity sin^2(x)+cos^2(x)=1, we can replace cos^2(x) with 1-sin^2(x)
0=3(1-sin^2(x))-sin^2(x)
Distribute
0=3-3sin^2(x)-sin^2(x)
Combine like terms
0=3-4sin^2(x)
Add 4sin^2(x) on both sides
4sin^2(x)=3
Divide both sides by 4
sin^2(x)=3/4
Take the square root of both sides
sin(x)=+ or - sqrt(3/4)
sin(x)=+ or - sqrt(3)/sqrt(4)
sin(x)=+ or - sqrt(3)/2
This happens on the unit circle at
60 degrees
120 degrees
240 degrees
300 degrees
If we go around and around again forwards or backwards, we get the infinitely many other solutions including the one's already stated in the following solution sets
(60 +360n) degrees
(120 +360n)degrees
(240 +360n)degrees
(300 +360n)degrees
where n is an integer
x is 120 degrees or (120+360n) degrees in the second quadrant. I didn't know if you were just looking for solutions in the first nonnegative cycle of the unit circle or not.
240 degree one or the (240+360n) degrees terminates in the third.

Find the median, Q1, Q3,and IQR
Answers
Answer:
Median --> 357.5
Q1 --> 298
Q3 --> 422
IQR > 124
Step-by-step explanation:
3 daily attendance at the water park: 346, 250, 433, 369, 422,298
Find the median, Q1, Q3,and IQR
Step 1
We rearrange the given data set
250, 298, 346, 369, 422, 433
a) The Median
The formula to find the Median
= 1/2( n + 1)th term
Where n = Number of terms = 6
Median = 1/2(6 + 1)th
= 1/2(7)th term
= 3.5th term
The 3.5th term = The number between the 3rd and 4th term
3rd term = 346
4th term = 369
Hence,Median = 346 + 369/2
= 357.5
2) Q1 = First Quartile
= 1/4(n + 1)the
= 1/4( n + 1)th term
Where n = Number of terms = 6
Median = 1/4(6 + 1)th
= 1/4(7)th term
= 1.75th term
The 1.75th term = 2nd term
= 298
Q1 = 298
3) 3/4( n + 1)th term
Where n = Number of terms = 6
Median = 3/4(6 + 1)th
= 3/4(7)th term = 21/4th term
= 5.25th term
The 5.25th term = 6th term
Q3 = 422
4) Interquartile Range = Q3 - Q1
= 422 - 398
= 124

2. 20
Step-by-step explanation:
1. Simply replace x with 2, since x=2. 2x -3 is the same as -3+-3, which is -6.
2. Simply replace x with 2, since x=2. 2x5 is the same as 5+5, which is 10. 10+10=20, therefore, the answer is 20.

The amount of money, A, accrued at the end of n years when a certain amount, P, is invested at a compound annual rate, r, is given by A= P(1+r) If a person invests $310 in an account that pays 8% interest compounded annually, find the balance after 5 years.
Answers
Answer:
A = $455.49
Step-by-step explanation:
A= P(1+r) ^t
P = $310
R = 8% or 0.08
T = 5
Put variables in the above equations
A = 310 (1+0.08)^5
A= 310(1.08) ^ 5
A = $455.49

the right answer is:
(A) [tex]2+\frac{1}{2}a[/tex]Step-by-step explanation:
You take the equations that the exercise give you:
x + y = 4x - y = aNow you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:
x - y = a-y = a - x3. y = x - a
And now, you'll replace this third equation in the equation you didn't take (the first in this case).
x + y = 4x + (x - a) = 4x + x - a = 4Add the x variables:
2x - a = 42x = 4 + ax = (4 + a) / 2That's the answer of the exercise, but you can represent this in this form:
x = (4 + a) / 2 ↔ [tex]x = \frac{4}{2} + \frac{1}{2} a[/tex]x = (4 + a) / 2 ↔ [tex]x = 2+ \frac{1}{2} a[/tex]By this reason, the right answer is [tex]x = 2+ \frac{1}{2} a[/tex].
