Answer:
0.64 = 64% probability that John will have company on the way to school
Step-by-step explanation:
John will have company when:
He rides with his friends(0.11 probability).
His parents take him(0.53 probability).
What is the probability that John will have company on the way to school?
0.11 + 0.53 = 0.64
0.64 = 64% probability that John will have company on the way to school
Express as a difference. 7+3. Please explain.
Answer:
7 + 3 = 10, difference means the answer to a subtraction problem, not sure I understand the question
Step-by-step explanation:
The given expression (7 + 3) represented in difference form as [tex]7-(-3)[/tex]
Difference of numbers :
We have to express 7 + 3 as difference of two number.
As we know that,
[tex]a-(-b)=a+b[/tex]
In above expression, (a + b) is difference of two number a and -b.
Similarly,
[tex]7+3=7-(-3)[/tex]
Thus, (7 + 3) represented in difference form as [tex]7-(-3)[/tex]

For degrees F
Add triangles have a angle sum of 180
So you just subtract 180 by the angles in the triangle
180 - 91 = 89
89 - 43 = 46
46 is remaining so it is the missing degrees ( F )

Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 5.3 per year. a. Find the probability that in a year, there will be 3 hurricanes. b. in a 45-year period, how many years are expected to have 3 hurricanes ? c. How does the result from part (b) compare to a recent period of 45 years in which 5 years had 3 hurricanes? Does the Poisson distribution work well here?
Answer:
a) 0.12386 = 12.386% probability that in a year, there will be 3 hurricanes.
b) 5.57 years are expected to have 3 hurricanes, that is, between 5 and 6 years.
c) 5 years is very close to the mean of 5.57, which means that the Poisson distribution works well here.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
The mean number of hurricanes in a certain area is 5.3 per year.
This means that [tex]\mu = 5.3[/tex]
a. Find the probability that in a year, there will be 3 hurricanes.
This is P(X = 3).
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = x) = \frac{e^{-5.3}*5.3^{3}}{(3)!} = 0.12386[/tex]
0.12386 = 12.386% probability that in a year, there will be 3 hurricanes.
b. in a 45-year period, how many years are expected to have 3 hurricanes ?
0.12386 each year. So, for 45 years:
45*0.12386 = 5.57
5.57 years are expected to have 3 hurricanes, that is, between 5 and 6 years.
c. How does the result from part (b) compare to a recent period of 45 years in which 5 years had 3 hurricanes? Does the Poisson distribution work well here?
5 years is very close to the mean of 5.57, which means that the Poisson distribution works well here.

What is the slope of the line shown below?
Answer:
A. 2
Step-by-step explanation:
Formula for slope of a line (m) = change in y / change in x = ∆y/∆x
Using the coordinates of two points on the line, (1, -4) and (6, 6):
Slope (m) = (6 - (-4)) / (6 - 1) = 10/5 = 2
Slope (m) = 2
Find the error then show the correct way step by step.
Question 4
The error was that in step 2, when distributing -3 into the parentheses, the person did not change the sign of 24 so that it was negative, since a negative number multiplied by a positive number will always make a negative number. Here is the correct way to solve this equation:
[tex]-5x+12-7x=-3(5x+8)\\-12x+12=-3(5x+8)[/tex]
Distrubute -3 into the parentheses
[tex]-12x+12=-15x-24[/tex]
Subtract both sides by 12
[tex]-12x+12-12=-15x-24-12\\-12=-15x-36[/tex]
Add 15x to both sides
[tex]-12+15x=-15x-36+15x\\3x=-36[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} =\frac{-36}{3} \\x=-12[/tex]
Question 5
The error was that 2 was added on both sides in step 5 instead of being subtracted from both sides. Here is the correct way to do it, starting from step 4:
[tex]10=16x+2[/tex]
Subtract both sides by 2
[tex]10-2=16x+2-2\\8=16x[/tex]
Divide both sides by 16
[tex]\frac{8}{16} =\frac{16x}{16} \\\frac{1}{2}=x[/tex]

The solution is, the area of the following figure is 360 in^2.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
For this case we have that by definition, the area of a rectangle is given by:
A = l*w
In this case, the rectangle is 18 in side, & 21 in.
then:
A = 18*21
= 378
On the other hand, the area of a triangle is given by:
A = 1/2 b * h
Where:
b: It is the base of the triangle
h: It is the height
We have according to the figure that:
b = 21 - 17 = 4
h = 18 - 9 = 9
So:
A = 1/2 *4 *9
=18
Finally, the area of the figure is:
378 - 18
=360
Answer: The solution is, the area of the following figure is 360 in^2.
