Answer:
107° 30'
Step-by-step explanation:
As in part (a), the hour hand moves 30° per hour, so at 1:25, it has moved ...
(1 25/60)(30°) = 42.5°
from the vertical at noon.
Similarly, the minute hand moves 6° per minute, so at 1:25, it has moved ...
(25)(6°) = 150° from the vertical at 1 o'clock.
The exact angle difference is ...
150° -42.5° = 107.5° = 107° 30'

3 to the power of negative 2 is equivalent to what 1/9 1/6 -6 -9
Answer:
1/9
Step-by-step explanation:
You have 3 to the power of -2.You must take that and turn it into 1/3 to the power of 2, so now the exponent is no longer negative and therefore can be solved.After solving the exponent, you are left with 1/9 as your answer.The hypotenuse of a right triangle is 15cm long. One of the triangle’s legs is two times the length of the other leg. Find the lengths of the three sides of the triangle. For non-integer answer(s), round your answer(s) to the nearest tenth. 1
Step-by-step explanation:
Given that,
The hypotenuse of a right triangle is 15 cm
Let x is the length of the other leg. So, the length of the first leg is 2x.
Using Pythagoras theorem for the right angle triangle such that,
hypotenuse² = base²+height²
Let base is x and height is 2x
So,
[tex]15^2=x^2+(2x)^2\\\\225=x^2+4x^2\\\\225=5x^2\\\\x^2=45\\\\x=3\sqrt{5} \ cm[/tex]
Hence,
Base = [tex]3\sqrt{5} \ cm[/tex]
Height = [tex]2\times 3\sqrt{5} \ cm=6\sqrt5\ cm[/tex]
Hyoptenuse = 15 cm (given)
This histogram shows the percentage of the population that smokes tobacco for 123 countries. Which one of the following values is the most reasonable estimate for the IQR?
Answer:
9.5
Step-by-step explanation:
The formula for interquartile range = Third Quartile - 1st Quartile
= Q3 - Q1
Looking at the histogram given, the class width = 6
Step 1
We find the number of values = n
n = 1 + 12 + 26 + 27 + 31 + 19 + 6 + 1
= 123
Frequency Cumulative Frequency
1 1
12 13
26 39
27 66
31 97
19 116
6 122
1 123
Step 2
We find Q1 ( First Quartile)
Q1 =1/4 (n + 1) value
Q1 = 1/4(124) value
= 31st value
The first Quartile = 31st value
31 - 13 = 18
31st value = 12 + (18/26 × class width)
= 12 +( 18/26 × 6)
First Quartile = 16.153846154
Third Quartile =Q3 =3/4 (n + 1) value
Q1 = 3/4(124) value
= 93rd value
The first Quartile = 93rd value
93 - 66 = 27
93rd value = 1 + (27/97 × class width)
=24 +( 27/97 × 6)
Third Quartile= 25.670103093
Interquartile range = Q3 - Q1
= 25.670103093 - 16.153846154
= 9.5162569392
Approximately = 9.5
Inter Quartile range = 9.5

Two brown and 8 red birds are flying. What is the probability that two brown sit together?
The probability that two brown sit together is 0.2.
What is the meaning of arrangements?
the act of putting things in order
Here, it is given that ;
there are Two brown and 8 red birds.
Total number of ways 10 distinct birds can sit = 10!
Now,
When out of total arrangement the number of ways in which two brown birds and 8 red birds can sit is :
¹⁰C₂ = 10!/ (2! x 8!)
¹⁰C₂ = 45 ways
Now, consider two brown birds as one bird then the number of arrangement will be :
⁹C₁ = 9!/1! = 9
The probability that two brown sit together will be :
9/45 = 0.2
Therefore, the probability that two brown sit together is 0.2.

A truck leaves Pensacola heading east at 50 mph. One hour later, a second
truck leaves Pensacola heading east at 65 mph. How long will it take the
second truck to overtake the first truck?
Answer:
The answer is 10/3.
Step-by-step explanation:
Think of position. After one hour just as the fast truck starts, the slow truck is at a position 50 miles. Let's see where they aree at time t hours after the fast truck begins his trip: Slow Truck: 50 miles + (50 miles/hour)×t Fast Truck: (65 miles per hour)×t .
What is t when their positions are the same?
50 + 50t = 65t
50 = 65t - 50t
50 = 15t
50/15 = t
10/3 = t
t = 10/3.

A sector of a circle of radius has an area of . Find the central angle of the sector. Do not round any intermediate computations. Round your answer to the nearest tenth
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, But I would show how to solve the problem
The area of a sector of a circle with radius r and a subtended central angle θ in degree has an area of:
Area = [tex]\frac{\theta}{360}*\pi r^2[/tex]
Where θ is in degrees.
If the central angle is in radian, then the area of the sector is given as:
[tex]Area=\frac{\theta}{2\pi}*\pi r^2\\ Area=\frac{\theta}{2}* r^2[/tex]
Let us assume A circle has a radius of 2.5 mm a sector of the circle has a central angle of 4 pi/3 radians.
Therefore the radius (r) = 2.5 mm and the central angle (θ) = 4π/3
Therefore:
[tex]Area=\frac{\theta}{2}*r^2\\ \\Area=\frac{\frac{4\pi}{3} }{2} *2.5^2=13.1\ mm^2\\[/tex]

Suppose that a factory worker turns 62 years old and retires from her job. Which statistic is not affected
Answer:
The question is not complete, below is the complete question:
Suppose that a factory worker turns 62 years old and retires from her job. Which statistic is not affected? A. number of unemployed B. unemployment rate C. labor force D. labor-force participation rate
Answer:
The correct andwer is:
number of unemployed (A.)
Step-by-step explanation:
The terms highlighted in the options of the question refer to terms associated with the labour force of an economy. Let us take a look at each of them and justify why we chose the option A
1. Number of unemployed: The number of unemployed in an economy refers to the number of people who are without employement, while actively searching for employment, willing to work and have actively sought for employment in the past four weeks. In this example, a factory worker retiring at 62 is not actively looking for work anymore, hence this transition does not affect the number of unemployed individuals in an economy
2. unemployment rate: The unemployment rate refers to the percentage of labor force that is jobless. Mathematically, it is represented as:
[tex]Unemployment\ rate\ =\ \frac{umemployed}{Labour\ force} \times\ 100[/tex]
In this example, a factory worker retiring at 62, reduces the labor force (number fit to work) in a population, and since the unemployment rate is in turn affected by the labour force (inversely), the unemployment rte is affected by the retiring of the factory worker
3. Labor force: The labor force in an economy are all the individuals who are fit and able to work. It inclues all those who are actively employed and those who are unemployed. A retired factory worker is not part of the labor force, because retirement age disqualifies him/her from being fit to work, hence the retirement reduces the labor force.
4. Labor-force participation rate: This is the coolective numbere of civilians or non-institutional people 16 years or older, who are working or actively looking for work. Retirement reduces the labor-force participation rate

Find an equation of the line passing through the point (−6,−5) that is parallel to the line y=4/3x−5
Answer:
y = [tex]\frac{4}{3}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{4}{3}[/tex] x - 5 ← is in slope- intercept form
with slope m = [tex]\frac{4}{3}[/tex]
Parallel lines have equal slopes, thus
y = [tex]\frac{4}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 6, - 5) into the partial equation
- 5 = - 8 + c ⇒ c = - 5 + 8 = 3
y = [tex]\frac{4}{3}[/tex] x + 3 ← equation of parallel line
