The probability of a hurricane forming in the northern hemisphere, given that a tropical cyclone has already formed, is:
P(hurricane | northern hemisphere) = (379/1308) / (821/1308) = 379/821
then round to the tenths place: P(hurricane | northern hemisphere) = 379/821 x 100% ≈ 46.1%
What is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
To find the probability of a hurricane forming in the northern hemisphere, given that a tropical cyclone has already formed, we use the formula for conditional probability:
P(hurricane | northern hemisphere) = P(hurricane and northern hemisphere) / P(any tropical cyclone)
The probability of a hurricane forming in the northern hemisphere is given in the table as 379 out of the total number of tropical cyclones:
P(hurricane and northern hemisphere) = 379/1308
The probability of any tropical cyclone forming is the sum of the probabilities of all three types of tropical cyclones:
P(any tropical cyclone) = (100+342+379)/1308 = 821/1308
Therefore, the probability of a hurricane forming in the northern hemisphere, given that a tropical cyclone has already formed, is:
P(hurricane | northern hemisphere) = (379/1308) / (821/1308) = 379/821
This can be simplified by dividing both the numerator and denominator by the greatest common factor (gcd) of 379 and 821, which is 1:
P(hurricane | northern hemisphere) = 379/821
To express this as a percent rounded to the tenths place, we can divide 379 by 821 and multiply by 100, then round to the tenths place:
P(hurricane | northern hemisphere) = 379/821 x 100% ≈ 46.1%

Individual A has a circle of five close friends (B, C, D, E, and F). A has heard a certain rumor from outside the circle and has invited the five friends to a party to circulate the rumor. To begin, A selects one of the five at random and tells the rumor to the chosen individual. That individual then selects at random one of the four remaining individuals and repeats the rumor. Continuing, a new individual is selected from those not already having heard the rumor by the individual who has just heard it, until everyone has been told.
a. What is the probability that the rumor is repeated in the order B, C, D, E, and F?
b. What is the probability that F is the third person at the party to be told the rumor?
c. What is the probability that F is the last person to hear the rumor?
d. If at each stage the person who currently "has" the rumor does not know who has already heard it and selects the next recipient at random from all five possible individuals, what is the probability that F has still not heard the rumor after it has been told ten times at the party?
Answer:
Step-by-step explanation:
From the given information;
The possible number of ways to select these people in order B, C, D, E, and F is:
= 5 × 4 × 3 × 2 × 1
= 120
However, using the order B, C, D, E, and F; The probability that the rumor is repeated is:
= 1/120
= 0.0083
b)
If we make F the subject here by selecting it such that F has not been selected in the first and second draw;
Then:
The possible numbers of ways to select F as third = 4 × 3 × 2 × 1
= 24
Now;
the required probability of F is the third person: = 24/120
= 0.2
c)
Suppose F is selected as the last person to hear the rumor;
Then, the selection of F in the last row = 4 × 3 × 2 × 1
Recall that; the total possible number of ways to select the person is B, C, D,E, and F which is = 120
Then, the required probability of F as the last person to hear the rumor is:
= 24/120
= 0.2
d)
Here, the required probability of F since F has not heard the rumor after it has been told tren times is:
= 4¹⁰
Let's no forget that the total number of possible ways to select the persons using the above criteria is = 5¹⁰
Thus, the required probability of F = 4¹⁰/5¹⁰
= 0.1074

what is the additive identity of the complex number 19+5i
The additive identity is z = 0 + 0i
What is the additive identity of the complex number?We know that the additive identity is a number that when we add it to our number, it does not change.
So the additive identity X is defined, for any number A, as:
A + X = A
So we want a complex number z = a + bi
such that:
19 + 5i + z = 19 + 5i
It is trivial to notice that:
z = 0 + 0i = 0
So the additive identity is 0 (just like for the case of real numbers).

A contractor better job at $750 for materials plus $43 per hour for labor. The total cost for the job can be modeled by C= 43H+ 750$.
Find the number of hours that he has for the job if the owner would like the total cost to be under $2000, rounded to the nearest hour.
The contractor has a maximum of 29 hours (rounded down) to complete the job while keeping the total cost under $2000.
To find the number of hours the contractor has for the job while keeping the total cost under $2000, we can use the given cost model equation: C = 43H + 750.
Since the owner wants the total cost to be under $2000, we can set up the inequality:
43H + 750 < 2000
Now, let's solve this inequality for H, the number of hours:
43H < 2000 - 750
43H < 1250
Dividing both sides of the inequality by 43:
H < 1250/43
To determine the maximum number of hours the contractor has for the job, we need to round down the result to the nearest whole number since the contractor cannot work a fraction of an hour.
Using a calculator, we find that 1250 divided by 43 is approximately 29.07. Rounding down to the nearest whole number, we get:
H < 29
Using the cost model equation C = 43H + 750, where C represents the total cost and H represents the number of hours, we set up the inequality 43H + 750 < 2000 to satisfy the owner's requirement of a total cost under $2000.
By solving the inequality and rounding down to the nearest whole number, we find that the contractor has a maximum of 29 hours to complete the job within the specified cost limit.

A building in a city has a rectangular base. The length of the base measures 70 ft less than twice the width. The perimeter of this base is 820 ft. What are the dimensions of the base?
Answer:
160 ft, 250ft
Step-by-step explanation:
Rectangular base:
Width = w
length =2w - 70
Perimeter = 820 ft
2*(length + width) = 820
2*(2w - 70 + w ) = 820
2 *(2w + w - 70) = 820 {Combine like terms}
2* (3w - 70) = 820
3w*2 - 70*2 = 820
6w - 140 = 820
6w = 820 + 140 {Add 140 to both side}
6w = 960 {Divide both sides by 6}
w = 960/6
w = 160 ft
length = 2*160 - 70
= 320 - 70
= 250 ft

The Reflexive Property is a property of equality that states that anything is equal to itself. This property is true for numbers, shapes, angles, and more.
In the context of geometry, the Reflexive Property of Congruence states that any geometric figure is congruent to itself. This includes angles, segments, triangles, and other polygons.
So, when you see "<J ≅ <J", it's saying that angle J is congruent to angle J, which is an application of the Reflexive Property. In other words, any angle is congruent (equal in measure) to itself.

Step-by-step explanation:
A. For diagram A, triangles ANC and BDE are similar. Thus, we can use similarity ratios to find the length of AC. (x+1)/12 = (x+5)/15. 15x+15=12x+60. Thus 3x=45, and x=15. Since we need to find AC, AC = 15+1 = 16.
B. For diagram B, triangles SRT and VUT are similar. Again, using similarity ratios, (4x-1)/14=(x+2)/6 or 14x+28=24x-6. 10x=34, x=3.4.
what are the features of the function g if g(x)= f(x+4) +8
The domain, range, x-intercept, or y-intercept of g(x) = f(x + 4) + 8. The features of g depend on the corresponding features of f.
Given the function g(x) = f(x + 4) + 8, let's examine its features:
Domain:
The domain of the function g will be the same as the domain of the function f, which depends on the restrictions or constraints of f. However, it is important to note that shifting the input by 4 units (x + 4) does not inherently change the domain unless there are specific restrictions imposed by f.
Range:
Similar to the domain, the range of the function g will depend on the range of the function f.
x-intercept:
The x-intercept of a function is the point where the graph intersects the x-axis, meaning the y-coordinate is zero (y = 0). To find the x-intercept of g(x), we set g(x) = 0 and solve for x.
0 = f(x + 4) + 8
By subtracting 8 from both sides:
-8 = f(x + 4)
Since the exact value of x that makes f(x + 4) equal to -8. The x-intercept will depend on the behavior of f.
y-intercept:
The y-intercept of a function is the point where the graph intersects the y-axis, meaning the x-coordinate is zero (x = 0). To find the y-intercept of g(x), we substitute x = 0 into the function:
g(0) = f(0 + 4) + 8
g(0) = f(4) + 8
Again, the specific value of f(4) will depend on the behavior of the function f.

Can someone help me with this please?
Answer:
The triangles are similar.
Explanation:
Similar triangles have 3 pairs of congruent angles. In this diagram, we can see that the triangles WXP and WYZ share angle W, which is congruent to itself; therefore, they have at least 1 pair of congruent angles. We are given that angle X is congruent to angle Y, so that is a second pair of congruent angles. Finally, we know that angle P is congruent to angle Z because if two pairs of corresponding angles are congruent, then the third pair must also be congruent because the measures of the interior angles of both triangles have to add to 180°.
Write an equation that represents the line. Use exact numbers.
Answer:
y = \(\frac{3}{4}\) x - \(\frac{9}{2}\)
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 )
calculate m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (- 2, - 6) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line
m = \(\frac{-3-(-6)}{2-(-2)}\) = \(\frac{-3+6}{2+2}\) = \(\frac{3}{4}\) , then
y = \(\frac{3}{4}\) x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (2, - 3 )
- 3 = \(\frac{3}{4}\) (2) + c = \(\frac{3}{2}\) + c ( subtract \(\frac{3}{2}\) from both sides )
- 3 - \(\frac{3}{2}\) + c , then
c = - \(\frac{9}{2}\)
y = \(\frac{3}{4}\) x - \(\frac{9}{2}\) ← equation of line
