(5 points) The probability of rain on any day in the month of April is 34%. The probability that it will be windy on any day in the month of April is 38%, and the probability of both is 10%. What is the probability that a randomly selected day in April will be rainy or windy?
Answer:
The probability that a randomly selected day in April will be rainy or windy is 0.62 or 62%.
Step-by-step explanation:
We are given that the probability of rain on any day in the month of April is 34%. The probability that it will be windy on any day in the month of April is 38%, and the probability of both is 10%.
And we have to find the probability that a randomly selected day in April will be rainy or windy.
Let the probability of rain on any day in the month of April = P(A) = 0.34
The probability of windy on any day in the month of April = P(W) = 0.38
The probability of both windy and rainy on any day in the month of April = P(R [tex]\bigcap[/tex] W) = 0.10
Now, the probability that a randomly selected day in April will be rainy or windy is given by = P(R [tex]\bigcup[/tex] W)
P(R [tex]\bigcup[/tex] W) = P(R) + P(W) - P(R [tex]\bigcap[/tex] W)
= 0.34 + 0.38 - 0.10
= 0.62 or 62%
So, the probability that a randomly selected day in April will be rainy or windy is 62%.

The area of a rectangular wall of a barn is 48 square feet. Its length is 10 feet longer than twice its width. Find the length and width of the wall of the barn.
l = 16 feet
w = 3 feet
Step-by-step explanation:A = l×w
l = 10+2w
48 = (10 + 2w)w
48 = 10w + 2w² | : 2
24 = 5w + w²
w² + 5w - 24 = 0
w² + 8w - 3w - 24 = 0
w(w + 8) - 3(w + 8) = 0
(w - 3)(w + 8) = 0
w - 3 = 0 => w = 3 feet
w + 8 = 0 => w = - 8 ∉ N
l = 10 + 2w
l = 10 + 6
l = 16 feet
A = l×w = 16ft×3ft = 48ft²

Use Theorem to find ℒ{f(t)}.
f(t) = (et − e−t)2
Answer:
[tex]\frac{3s^2-4}{s(s^2-4)}[/tex]
Step-by-step explanation:
Here, the question is to find the Laplace transformation of [tex]f(t)[/tex]
where, [tex]f(t)=(e^t-e^{-t})^2[/tex]
We know that for [tex]t>0[/tex], [tex]\mathcal{L}\{f(t)\} =\int_0^{\infty} e^{-st}f(t)dt[/tex]
[tex]\mathcal{L}\{e^{at}\}=\int_0^{\infty} e^{-st}e^{at}dt[/tex]
[tex]\Rightarrow \mathcal{L}\{e^{at}\}=\int_0^{\infty} e^{(a-s)t}dt[/tex]
[tex]\Rightarrow \mathcal{L}\{e^{at}\}=\left[\frac { e^{(a-s)}}{a-s}\right]_0^{\infty}[/tex]
[tex]\Rightarrow \mathcal{L}\{e^{at}\}=\frac { 1}{s-a}\cdots(i)[/tex]
Here, we have [tex]f(t)=(e^t-e^{-t})^2[/tex]
[tex]\Rightarrow f(t)=(e^t)^2+(e^{-t})^2-2(e^t)(e^{-t})[/tex]
[tex]\Rightarrow f(t)=e^{2t}+e^{-2t}-2e^{0t}[/tex]
So, the laplace transformation of [tex]f(t)[/tex] is
[tex]\mathcal{L}\{f(t)\}=\mathcal{L}\{e^{2t}+e^{-2t}-2e^{0t}\}[/tex]
[tex]\Rightarrow \mathcal{L}\{f(t)\}=\mathcal{L}\{e^{2t}\}+\mathcal{L}\{e^{-2t}\}+\mathcal{L}\{e^{0}\}[/tex]
Now, using equation[tex](i)[/tex]
[tex]\mathcal{L}\{f(t)\}=\frac{1}{s-2}+\frac{1}{s-(-2)}+\frac{1}{s-0}[/tex]
[tex]\Rightarrow \mathcal{L}\{f(t)\}=\frac{1}{s-2}+\frac{1}{s+2}+\frac{1}{s}[/tex]
[tex]\Rightarrow \mathcal{L}\{f(t)\}=\frac{3s^2-4}{s(s^2-4)}[/tex]
Hence, the Lapelace transformation of [tex]f(t)=(e^t-e^{-t})^2[/tex] is
[tex]\frac{3s^2-4}{s(s^2-4)}[/tex].
When determining how well an observed set of frequencies fits an expected set of frequencies, what is the test statistic
Answer: [tex]\chi^2[/tex] test statistic.
Step-by-step explanation:
The chi-square ([tex]\chi^2[/tex] ) test is a non-parametric statistical test(also known as Goodness of fit test) which is used to determine if a distribution of observed frequencies differs from the expected frequencies.
Chi-square statistic uses either nominal (categorical) or ordinal level data.
Hence, When determining how well an observed set of frequencies fits an expected set of frequencies, the test statistic is [tex]\chi^2[/tex] test statistic.
Determine the value of x shown in the diagram
Answer:
x = 145
Step-by-step explanation:
If we look at the right triangle with sides of 24 and 30, we can find the missing leg using the Pythagorean Theorem. If we look carefully, we notice that 18:24:30 is basically the 3:4:5 Pythagorean Triple multiplied by 6, so the missing side is 18. If we look at the right triangle with sides of x and 24, we can find the missing side by calculating 161 - 18 = 143. Using the Pythagorean Theorem, we know that 143² + 24² = x² so x = 145.
PLEASE HELP *13 POINTS*! A) -4 B) -0.25 C) 4 D) 0.25
Answer: Choice C) 4
=========================================
Work Shown:
Set the denominator equal to zero and solve for x
4x-16 = 0
4x-16+16 = 0+16 ... add 16 to both sides
4x = 16
4x/4 = 16/4 ... divide both sides by 4
x = 4
--------
If x = 4, then the denominator is 0
4x-16 = 4(4)-16 = 16-16 = 0
So this x value is what we exclude from the domain to avoid a division by zero error.

What is the probability of choosing a card from a deck of cards that is a club or a ten? Is this event mutually
exclusive or inclusive?
A. Inclusive
B. Exclusive
A. 5/16
B. 4/13
C. 1/4
D. 7/16
Answer:
Hey there!
There are 13 clubs in a deck of cards.
There are 4 tens.
However, the tens overlap with the clubs, so there are 16 cards to choose.
16/52=4/13
Let me know if this helps :)
The events are mutually inclusive. Option B is correct because the required probability is [tex]\dfrac{4}{13}[/tex].
Important information:
A card is selected randomly from a deck of cards.We need to find the probability that the card is a club or a ten.Probability:A deck of cards has total 52 cards, which includes 4 suits and each suit has 13 cards. If S be the sample space, then n(S) = 52.
Let A be the event that the card is a club card and B be the event that it is a ten card.
The number of club cards is 13. So, n(A) = 13.
There are 4 cards of 10. So, n(B) = 4.
One ten card is of club. So, [tex]n(A\cap B)=1[/tex].
Since [tex]n(A\cap B)=1\neq 0[/tex], therefore the events are mutually inclusive.
The number of club or a ten card is:
[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]
[tex]n(A\cup B)=13+4-1[/tex]
[tex]n(A\cup B)=16[/tex]
Now,
[tex]P(A\cup B)=\dfrac{n(A\cup B)}{n(S)}[/tex]
[tex]P(A\cup B)=\dfrac{16}{52}[/tex]
[tex]P(A\cup B)=\dfrac{4}{13}[/tex]
Therefore, the probability of choosing a card from a deck of cards that is a club or a ten is [tex]\dfrac{4}{13}[/tex]. Hence, option B is correct.

Let p: x = 4 Let q: y = -2 Which represents if x = 4, then y = -2. Please hurry
Answer:
p: x = 4
q: y = -2
If p happens then q will also happen
Step-by-step explanation:
Given two propositions, we want to rearrange them in a conditional statement.
The correct answer is:
p → q
First, a conditional statement is something of the form:
If [Hypothesis] then [Conclusion]
So, if the first part is true, then the second part must be true.
Now, here we have two propositions:
p: "x = 4"
q: "y = -2"
We want to write:
"if x = 4, then y = -2"
this is just written as: "p implies q" or:
p → q
Where "→" means "then", and the initial "if" is tacit.

Greetings from Brasil...
We have to remember 2 details:
→ When X = 0, the function intersects the Y axis
→ When Y = 0, the function intersects the X axis
So
1: X = 0
Y = X + 5
Y = 0 + 5
Y = 5
X = 0 and Y = 5 ⇔ (0; 5)
2: Y = 0
Y = X + 5
0 = X + 5
X = - 5
Y = 0 and X = - 5 ⇔ (- 5; 0)
Then the point at which the graph intersects the X and Y axis will be
(0; 5) and (- 5; 0)
Janet wants to calculate the time it takes to earn a certain amount of interest on a principal amount in an investment with simple interest. What equation can she use?
Answer:
T = 100I/PRStep-by-step explanation:
Given the amount invested for a particular period of time at an interest rate, the equation that can model the Interest achieved on investment is expressed using the simple interest formula as shown;
Simple Interest = PRT/100 where;
P is the principal (amount invested)
R is the rate (in %)
T is the time (in years)
From the equation I = PRT/100, we need to express tht time T as a function of the rest of the variable as shown;
I = PRT/100
cross multiply
100I = PRT
Divide both sides by PR
100I/PR = PRT/PR
100I/PR = T
Hence the the time it takes to earn a certain amount of interest on a principal amount in an investment with simple interest is expressed as
T = 100I/PR

The period T(in seconds) of a pendulum is given by T=2 pi root L over 32 where the L stands for Length(in feet) of the pendulum. If `pi 3.14, and the period is 3.14 seconds, what is the length?
Answer:
8 feet = L
Step-by-step explanation:
The period T(in seconds) of a pendulum is given by T=2 pi root L over 32
T= 2π√(L/32)
where the L stands for Length(in feet) of the pendulum.
If π= 3.14, and the period is 3.14 seconds
Length will be
T= 2π√(L/32)
3.14= 2*(3.14)√(L/32)
(3.14/3.14)/2= √(L/32)
(1/2)²= L/32
1/4 = L/32
32/4= L
8 feet = L

If speed varies inversely as the time it takes to drive and Kris takes 5 hours driving at 55 mph, what speed will Martin need to
drive if he wants to take 5 hours?
O 50 mph
52.4 mph
O 60.5 mph
O 51.5 mph
Answer:
55mph . None of the options are correct
Step-by-step explanation:
If the speed varies inversely as the time it takes to drive, then v ∝ 1/t. where;
v is the speed
t is the time taken
Hence;
v = k/t with k being the constant of proportionality.
Since it takes Kris 5 hours when driving at 55 mph, we will substitute v = 55mph and t = 5 hours. into the equation above to get the value of k as shown:
55 = k/5
Cross multiply
k = 55*5
k = 275
Hence, to calculate the speed it will Martin to drive for 5 hours, we will substitute k = 275 and t = 5 into the original equation v = k/t as shownl
v = 275/5
v = 55 mph
Hence, we can conclude that Martin will also need to drive at a speed of 55mph if he wants to take 5hours.
