Answer: Unlikely
Step-by-step explanation:
We know that,
When the probability of an event is
100% , then it is known as certain.0% , then it is known as uncertain.<50% then , it is unlikely to happen.>50% then it is likely to happen.Given : The probability of a hurricane being within 100 miles of a location in two days is 40%.
Event : " Hurricane being within 100 miles of a location in two days "
Clearly, 40% < 50%.
Therefore , it unlikely to happen a hurricane being within 100 miles of a location in two days.

A 7.5 force is applied to a football, causing an acceleration of 15 m/s2. Calculate the mass
of the football.
Step-by-step explanation:
We know that we have the formula that F = ma
Given
Force (F) = 7.5 N
Acceleration (a) = 15 m/s²
Mass (m) = ?
Now
F = ma
7.5 = m * 15
m = 7.5/ 15
Mass = 0.5 kg
The mass of the football is 500 g.
Step-by-step explanation:
Given,
F = 7.5 N
Acceleration (f) = 15 m/s²
To find the mass (m) of the ball.
Formula
F = mf
According to the problem,
m×15 = 7.5
or, m = [tex]\frac{7.5}{15}[/tex] = 0.5 kg = 500 g
Hence,
The mass of the football is 500 g.

A bag contains 25 cents and 50 cent coins whose total value is $30 if the number of 25 cent coins is four times that of 50 cent coins, find the number of each type coins. please may I also have the equation.
Number of 25 cents coins is 80 and number of 50 cents coins is 20.
Step-by-step explanation:
Given,
A bag contains of total value $ 30.
Number of 25 cent coins is four times that of 50 cent coins.
To find number of 25 cents coin is x
Number of 50 cents coin is y
According to the problem,
[tex]\frac{x}{4} +\frac{y}{2} = 30[/tex] ----- eq 1
x = 4y------ eq 2
Now, we will solve these two equation.
Putting the values of x = 4y in eq 1 we get,
[tex]\frac{4y}{4} +\frac{y}{2} = 30[/tex]
or, [tex]y +\frac{y}{2} = 30[/tex]
or, [tex]\frac{3y}{2}[/tex] = 30
or, y = 20
So, x = 4×20 = 80
Hence,
Number of 25 cents coins = 80 and number of 50 cents coins = 20
Answer:
Step-by-step explanation:
Let 25 cent coin be A and 50 cent coin be B
Given
Total value of 25 cents coin and 50cents coin is $30
That’s
25A + 50B = 30
Also, 25 cents coin is equal to four times that of 50
So,
A = 4B
We now have
25A + 50B = 30
A = 4B
Substitute 4B for A into the first equation
25(4B) + 50B = 30
25 x 4B + 50B = 30
100B + 50B = 30
150B = 30
Divide both sides by 150 to isolate B
150B/150 = 30/150
B = 1/5
Recall
A = 4B
Therefore
A = 4 x 1/5
= 4/5
Number of 25 cents coin is 4/5 and that of 50 cents coin is 1/5

O A unit of measure must be defined for distance.
O The distance along the arc has no relation to the angle measure between the two points
O The radius of the circle must be measured
O The circle must be drawn on a coordinate plane
Answer:
The radius of the circle needs to be measured for the whole circle meaning that if you subtract the two points from the circle's area you'd get the distance of the arc

What is the length of chord VI in OC below?
A. 18.6 units
B. 9.4 units
C. 4.7 units
D. 9.3 units
The length of the chord of the circle is VI = 9.3 units
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the circle be represented as O
Now , the center of the circle is C
And , the two chords of the circle are AR and VI
where the length of the chord CR = 9.3 units
The chords are separated by a distance ( 4.7 + 4.7 ) units = 9.4 units
So , the chords are congruent or equal in distance
Hence , the chord VI = 9.3 units

A restaurant noted what type of food its customers ordered last week. Here are the results:
Burger
Fries
30%
40%
10%
20%
Find the probability that a randomly chosen customer ordered a burger given that they ordered fries.
P (burger fries) =
Answer:
0.80
Explanation:
Since the results are not shown properly, I attach the picture with full question inlcuding the diagram that shows the results correctly.
You need to determine P(burger|fries)
That is the ratio of people that ordered burgers from the set of people that ordered fries (the intersection of the two circles) to the total people who ordered fries (the blue circle, including the intersection of the two circles).
The venn diagram shows that the set of people who ordered fries was 10% + 40% = 50% (the percentage inside the blue circle, including the intersection with the purple circle)
And from that set, the subset of people who also ordered burgers is 40% (the intersection of the two circles).
Thus, the probability that a randomly chosen customer ordered a burger given that they ordered fries is:
[tex]P(burger\mid fries)=\dfrac{P(burger\cap fries)}{P(fries)}[/tex]
[tex]{P (burger\mid fries)=\dfrac{40\% }{50\% }=0.80=80\%[/tex]
The probability that a randomly chosen customer ordered a burger given that he ordered fries is 80%.
To determine the probability that a randomly chosen customer ordered a burger given that he ordered fries, the following calculation must be performed:
Fries = 10% Fries and burgers = 40% Burgers = 30% None = 20% Fries + Fries and burgers = 50% 50 = 100 40 = X 40 x 100/50 = X 80 = X
Therefore, the probability that a randomly chosen customer ordered a burger given that he ordered fries is 80%.

At a tennis event, 10% of a player's score is based on serves, 40% on return balls, and 50% on wins.
Kyle makes 85% of his serves, returns 70% of the balls, and wins 75% of his games.
What is Kyle's score at the tennis event?
Answer:
74 % score
Step-by-step explanation:
Player score = 10% * (S) + 40%*(R) + 50%*(W)
S = serves
R = return balls
W= wins
S = .85
R = .7
W = .75
Player's score = 0.1* 0.85 + 0.4 * 0.7 + 0.5*(0.75)
Player's score = 0.085 + 0.28 + 0.375 = 0.74 = 74%
