If a sample mean is 92, which of the following is most likely the range of possible values that best describes an estimate for the population mean?
A. (80, 112)
B. (82, 114)
C. (76, 108)
D. (78, 110)
Answer:
I think it's c. (76,108)
Step-by-step explanation:
because 76+108 = 184 - half of which is the mean
so c. is more likely
(76, 108) is the range of possible values that best describes an estimate for the population mean.
The given sample mean is 92.
(80, 112)= 80+112/2
=96 which is not equal to 92.
(82, 114)=82+114/2
=98 which is not equal to 92.
(76, 108)= 76+108/2=92
The value 92 which is equal to 92.
(78, 110) = 78+110/2
=94 which is not equal to 92.
(76, 108) is the range of possible values that best describes an estimate for the population mean.

Two angles are vertical angles. One angle is ( 8x + 15 ) and the other angle is 143. Solve for x.
Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143

Answer:
first option
Step-by-step explanation:
Given
y = 2(x - 3)² + 1
Rearrange making x the subject
Subtract 1 from both sides
y - 1 = 2(x - 3)² ( divide both sides by 2 )
[tex]\sqrt{\frac{y-1}{2} }[/tex] = (x - 3)² ( take the square root of both sides )
± [tex]\sqrt{\frac{y-1}{2} }[/tex] = x - 3 ( add 3 to both sides )
± [tex]\sqrt{\frac{y-1}{2} }[/tex] + 3 = x
Change y into terms of x with x being the inverse, that is

Step-by-step explanation:
A high school soccer team is going to Columbus to see a professional soccer game. A coordinate grid is superimposed on a highway map of Ohio. The high school is at point (3, 4) and the stadium in Columbus is at point (7, 1). The map shows a highway rest stop halfway between the cities. What are the coordinates of the rest stop? What is the approximate distance between the high school and the stadium? (One unit = 6.4 miles.)
Answer:
a) The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].
b) The approximate distance between the high school and the stadium is 32 miles.
Step-by-step explanation:
a) The rest stop is located in the midpoint of the line segment between the high school and the stadium. Vectorially speaking, we use the following formula:
[tex]C(x,y) = \frac{1}{2}\cdot A(x,y) + \frac{1}{2}\cdot B(x,y)[/tex] (1)
Where:
[tex]A(x,y)[/tex] - Coordinates of the high school.
[tex]B(x,y)[/tex] - Coordinates of the stadium.
[tex]C(x,y)[/tex] - Coordinates of the rest stop.
If we know that [tex]A(x,y) = (3, 4)[/tex] and [tex]B(x,y) = (7,1)[/tex], then the coordinates of the rest stop are, respectively:
[tex]C(x,y) = \frac{1}{2}\cdot (3, 4) + \frac{1}{2}\cdot (7, 1)[/tex]
[tex]C(x,y) = \left(\frac{3}{2}, 2 \right) + \left(\frac{7}{2}, \frac{1}{2} \right)[/tex]
[tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex]
The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].
b) The approximate distance between the high school and the stadium ([tex]d[/tex]), in miles, is the product of the Length Equation of the Line Segment and the scale factor:
[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex] (2)
Where:
[tex]r[/tex] - Scale factor, in miles.
[tex]\Delta x[/tex], [tex]\Delta y[/tex] - Horizontal and vertical distances between the high school and the stadium, no unit.
If we know that [tex]r = 6.4\,mi[/tex], [tex]\Delta x = 4[/tex] and [tex]\Delta y = -3[/tex], then the distance between the high school and the stadium is:
[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex]
[tex]d = (6.4\,mi)\cdot \sqrt{4^{2}+(-3)^{2}}[/tex]
[tex]d = 32\,mi[/tex]
The approximate distance between the high school and the stadium is 32 miles.

Thomas Ran 2 miles at track practice Maria ran 50 yards more than half as far as Thomas how many yards did Maria run
Answer: 1810 yards

Given
Thomas ran 2 miles and Maria runs 50 yards more than half as far as Thomas
We know, 1 mile is equal to 1760 yards
So, Thomas run [tex]2\times 1760=3520\ \text{yards}[/tex]
half of its distance is 1760 yards

A student flips a coin three times. What is the probability the coin lands tails up exactly two times?
Answer:
1:3
Step-by-step explanation:
I believe this would be right
The probability the coin lands tails up exactly two times is 3/8
How to determine the probability?When a coin is flipped three times, the sample space is;
S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
In the above sample space, there are 3 occurrences where the coin lands tail up, out of the 8 occurrences.
So, the probability is:
P = 3/8
Hence, the probability the coin lands tails up exactly two times is 3/8
