What does a country need to do to keep a republic, and not fall under the power of a dictator?
Answer:
Continue to provide equality for all!
Step-by-step explanation:
When rules and regulations are in place, the government runs smoothly but also people still need to have a voice because without us - there is no government(social contract). We the people(constitution) have the power to prevent a dictator.

If a spinner for a game is spun once, there is a 25% chance it will land on
orange. What is the chance that the spinner will not land on orange on both
the first and second spin in a game? Calculate the probability as a decimal
rounded to the nearest TENTH.
Answer:
[tex]Pr = 0.6[/tex]
Step-by-step explanation:
Given
Let
[tex]O \to Orange[/tex]
So:
[tex]P(O) = 25\%[/tex] --- probability of O
[tex]n=2[/tex] --- Number of spin
Using the complement rule, the probability that a spin will not land on orange is:
[tex]P(O') = 1 - P(O)[/tex]
[tex]P(O') = 1 - 25\%[/tex]
Express as decimal
[tex]P(O') = 1 - 0.25[/tex]
[tex]P(O') = 0.75[/tex]
On two spins, the probability that it will not land on orange is:
[tex]Pr = P(O') * P(O')[/tex]
So, we have:
[tex]Pr = 0.75* 0.75[/tex]
[tex]Pr = 0.5625[/tex]
[tex]Pr = 0.6[/tex] --- approximated

Next you multiply 3.6 by 90 to get 324
An airplane flying into a headwind travels the -mile flying distance between Indianapolis, Indiana, and Phoenix, Arizona, in hours. On the return flight, the airplane travels this distance in hours and minutes. Find the airspeed of the plane and the speed of the wind, assuming that both remain constant.
Answer:
the airspeed of the plane = 660 miles/hr
the speed of the wind = 60 miles/hr
Step-by-step explanation:
The values are missing in the given information in the question.
To able to solve this question, we will make some assumptions.
Let's assume that:
The airplane heading into the wind travels 1800 miles in 3 hours.
While returning via the same distance, it travels 2 hours 30 minutes.
We are to determine the plane's airspeed as well as the wind speed.
First, let us say that the speed of the plane is p and the wind speed is q
during the time the plane is traveling for 1800 miles in 3 hrs.
Then, we can say
3p -3q = 1800 ----- (1)
However, in 2hours 30 minutes, we have 2.5 hours
So, when the plane is returning, we have the following equation:
2.5p + 2.5q = 1800 ---- (2)
So, to find p and q, we can use the elimination method.
Simply by multiplying equation (1) with 5 and equation (2) with 6
(5)3p - (5)3q = (5) 1800
(6)2.5p + (6)2.5q = (6) 1800
15p - 15q = 9000
+
15p + 15q = 10800
30p - 0 = 19800
30p = 19800
p = 19800/30
p = 660
Since p = 660, then from equation (1) we can obtain the value of q:
So; Using equation (1):
3p -3q = 1800
3(660) - 3q = 1800
1980 - 3q = 1800
-3q = 1800 - 1980
-3q = -180
q = 180/3
q = 60
Therefore, the airspeed of the plane = 660 miles/hr
the speed of the wind = 60 miles/hr
Your hose fills a swimming pool in 3 hours. When your friend's hose is used together with your hose, the pool is full in 1 hour. How long (in hours) does it take your friend's hose to fill the pool when working alone
Answer:
1.5 hours
Step-by-step explanation:
Given :
My hose = 3 hours ; my rate = 1/3
Let My friend's time = x ; his rate = 1/x
Combined time = 1 hour, combined rate = 1/1 = 1
Combined rate :
1/3 + 1/x = 1
1/x = 1 - 1/3
1/x = (3 - 1)/ 3
1/x = 2/3
Cross multiply :
3 = 2x
x = 3/2
x = 1.5 hours
There are 4 oranges, 7 bananas, and 5 apples in a fruit basket. Mansour selects a piece of fruit at random and then
Mahmoud selects a piece of fruit at random. Find the probability that two apples are chosen
Answer:1/12
Step-by-step explanation: 5/16 x 4/15 = 20/240= 1/12
Hi there I hope you are having an great day :) There are 4 oranges, 7 bananas, and 5 apples in a fruit basket. Mansour selects a piece of fruit at random and then Mahmoud selects a piece of fruit at random. Find the probability that two apples are chose. (5/16)*(4/15) Mya selects a fruit and you want it to be an apple so that is 5 apples out of 16 fruits total. After Mya selects one fruit and it is an apple, there is one less fruit and apple. So 5-1/16-1. Since the is also in one case, not two separate ones, you multiply the two fractions so (5/16)*(4/15).

The area of a rectangle is 259 cm sq and its length is 18.5cm find its breadth and perimeter
Answer:
Step-by-step explanation:
let it's breadth be x
area of rectabgle=l*b
259=18.5*b
259/18.5=b
14=b
perimeter of rectangle=2(l+b)
=2(18.5+14)
=2*32.5
=65 cm
Answer:
Breadth = 14 cm
Perimeter = 65 cm
Step-by-step explanation:
Length = [tex]18.5cm[/tex]Area = [tex]259cm^{2}[/tex] = l * b
Therefore, breadth = area / length
Breath = 259 / 185 = 1.4 * 10 = 14 cm
Perimeter = 2 * (l + b)Perimeter = 2 (18.5 + 14)
Perimeter = 2 (32.5)
Therefore, perimeter = 65 cm
I hope this helps :)

49-3m=4m+4 bbbbbbbbbbbbbbbbbbbbbbbb
Answer:
m = 6.43 (approx. )Step-by-step explanation:
49 - 3m = 4m + 4
=> 49 - 4 = 4m + 3m
=> 45 = 7m

In the circle shown, secants PE and PF have been drawn such that arc CE = 82, arc DF=98 and the ratio of arc CD to arc EF is 2:7. Determine the measure of angle P. Show how you arrived at your answer.
Answer:
m<P = 50°
Step-by-step explanation:
Given:
Arc CE = 82°
Arc DF = 98°
Ratio of arc CD to Arc EF = 2:7
Thus, let,
Arc CD = 2x
Arc EF = 7x
A full circle = 360°
Therefore,
Arc CE + Arc DF + Arc CD + Arc EF = 360°
Substitute
82° + 98° + 2x + 7x = 360°
Add like terms
180° + 9x = 360°
Subtract 180° from both sides
180° + 9x - 180° = 360° - 180°
9x = 180°
Divide both sides by 9
9x/9 = 180/9
x = 20
✔️Arc CD = 2x
Plug in the value of x
Arc CD = 2(20) = 40°
Arc EF = 7x = 7(20) = 140°
✔️Find m<P:
Recall: the measure of the external angle created when two secants intersect = half the difference of the major and minor arcs that are intercepted
Thus:
m<P = ½(arc EF - arc CD)
Substitute
m<P = ½(140° - 40°)
m<P = ½(100°)
m<P = 50°

The percent probability is = [ ? ]%
Round to the nearest percent.
Most likely, you won't need to type in the percent symbol since that seems to be already done for you.
=========================================================
Explanation:
The outcome "2" shows up 3 times, as shown in the first column. Let A = 3.
Add up all the values in the bottom row: 3+6+8+11+14+16+15+12+9+5+1 = 100. Let B = 100. This is the total number of dice rolls.
Dividing the two values gets us A/B = 3/100 = 0.03 = 3%
The value "2" shows up 3% of the time, which is the experimental probability of getting a "2".
