Jane is going to walk once around the edge of a rectangular park. The park is 300 yards long and 200 feet wide. How far will Jane walk?

Answers

Answer 1

Jane will walk 733.34 yards around the edge of the rectangular park after converting the width from feet to yards and calculating the perimeter.

Jane is going to walk once around the edge of a rectangular park. The park is 300 yards long and 200 feet wide. To determine how far Jane will walk, we need to calculate the perimeter of the rectangle. First, let's convert all measurements to the same unit. Since the length is given in yards and the width in feet, we can convert the width to yards (1 yard = 3 feet).

Width in yards: 200 feet \/ 3 feet per yard = 66.67 yards.

Now that both measurements are in yards, we can calculate the perimeter:

Perimeter = 2 ×(length + width) = 2 × (300 yards + 66.67 yards) = 2 ×366.67 yards = 733.34 yards.

Therefore, Jane will walk 733.34 yards around the edge of the park.

The value of y is inversely proportional to the value of x. When y=40, x=5. What is the value of y when x=8

Answers

Since x and y are inversely proportional:

xy = c, where c is a constant

when y = 40 and x = 5 -> c = 40*5 = 200

So xy = 200

Then, when x = 8, y = 200/8 = 25

A motorboat takes 3 hours to travel 108 km going upstream. The return trip takes 2 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?

Answers

recall your d = rt, distance = rate * time.

let's say the boat has a still water rate of "b", and the current has a a rate of "c", ok.... when the boat is going upstream, is not really going "b" fast, is going slower at "b - c", due to the current going in the opposite direction.

when the boat is coming downstream, is not going "b" fast either, is going faster, is going "b + c", due to the current adding speed to it.

we know the trip up was 108 kms, thus the return trip is also 108 kms.

[tex]\bf \begin{array}{lccclll} &distance&rate&time\\ &-----&-----&-----\\ Upstream&108&b-c&3\\ Downstream&108&b+c&2 \end{array} \\\\\\ \begin{cases} 108=3(b-c)\implies \cfrac{108}{3}=b-c\implies 36+c=\boxed{b}\\\\ 108=2(b+c)\\ --------------------\\ 108=2\left(\boxed{36+c} +c \right) \end{cases} \\\\\\ \cfrac{108}{2}=36+2c\implies 54=36-2c\implies \cfrac{54-36}{2}=c[/tex]

and surely you know how much that is.

what's the boat's speed? well, 36 + c = b.

Poisson suppose you have 5 cakes made ready to sell. what is the probability that you will sell out?

Answers

From question given, the selling of the cake is assumed to be a Poisson process.

Assume further that the mean number of cakes sold per day is lambda.

Let k=5 = number of cakes sold during the day, then the Poisson pmf (probability mass distribution) is given by
P(k)=lambda^k*e^(-lambda)/k!
or
P(5)=lambda^5*e^(-lambda)/5!
=lambda^5*e^(-lambda)/120

If the average number of cakes sold is 4 per day, then
P(5)=4^5*e^(-4)/120
=0.156 is the probability of selling exactly 5 cakes.

The probability of selling 5 cakes or more (i.e. the sixth and subsequent customers will be told to come back the next day) is then
P(k>=5)=1-(P(k=0)+P(k=1)+P(k=2)+P(k=3)+P(k=4)
=1-(0.018316+0.073263+0.146525+0.195367+0.195367)
=0.371163
(for mean number of cakes sold per day = 4 )

The upper leg length of 20 to 29-year-old males is normally distributed with a mean length of 43.7 cm and a standard deviation of 4.2 cm. a random sample of 9 males who are 20 to 29 years old is obtained. what it the probability that the mean leg length is less than 20 cm? 0.1894 pratically 0 0.2134 0.7898

Answers

Final answer:

The probability that the mean leg length is less than 20 cm is practically 0.

Explanation:

To find the probability that the mean leg length is less than 20 cm, we can use the sampling distribution of the sample mean. The sampling distribution of the sample mean is approximately normal when the sample size is large enough. In this case, the sample size is 9, which is smaller than 30 but still reasonably large, so we can assume that the sampling distribution of the sample mean follows a normal distribution.

We can standardize the sample mean using the formula:

z = (x - μ) / (σ / sqrt(n))

Where:

z: the z-scorex: the value of the sample meanμ: the population meanσ: the population standard deviationn: the sample size

Substituting the given values:

z = (20 - 43.7) / (4.2 / sqrt(9))

z = -23.7 / (4.2 / 3)

z = -23.7 / 1.4

z ≈ -16.93

Looking up the z-score in a standard normal distribution table, we find that the probability of getting a z-score less than -16.93 is practically 0. Therefore, the probability that the mean leg length is less than 20 cm is practically 0.

What is the integral of 1/x?

Answers

The indefinite integral is usually written as ln(x) if x>0, as u can see it's undefined for x = 0.

Final answer:

The integral of 1/x is the natural logarithm of the absolute value of x, plus an integration constant C. This expression is central to calculations in many areas of science and mathematics.

Explanation:

The integral of 1/x is known as the natural logarithm of the absolute value of x, plus a constant of integration, commonly referred to as C. In mathematical terms, this is expressed as:

[tex]$ \int \frac{1}{x} dx = \ln(|x|) + C $[/tex]

The natural logarithm arises due to the fundamental properties of the integral, and it's significant as it appears frequently across various fields of science and mathematics. While the basic form of integration of 1/x involves the natural logarithm, in applied examples like the cases mentioned above, where one works with additional functions or domain restrictions, the integral may lead to more complex expressions or even vanish under certain symmetry conditions.

What is the next number in the series? 71 62 53 44 35 ?

Answers

This is an arithmetic sequence with a common difference of -9, so the next term will be 35-9=26.

If you examine your sequence closely, you can notice that the number in the tens place is decreasing by 1 as the number in the ones place is increasing by 1.
To further prove this;
71 --> 62.
-10 and + 1.
62 --> 53.
-10 and +1
and so on.

However, if that's a little too complicated, there's an alternate method.
All you have to do is subtract 9 from the current number.
To further prove this;
71 - 9 = 62
62 - 9 = 53
53 - 9 = 44
and so on.

So, let's subtract 9 from our most current number, 35.
35 - 9 = 26.

The upcoming number in your sequence is 26.

Calculator Reference A mountaineer climbed 1,000 feet at a rate of x feet per hour. He climbed an additional 5,000 feet at a different rate. This rate was 10 feet per hour less than twice the first rate. Which expression represents the number of hours the mountaineer climbed?

Answers

so he climbed the first 1000ft in 1000/x hours then

the rate of the 5000ft is "10 feet per hour less than twice the first rate", so hmm twice the first rate is 2x, 10 less than that is 2x - 10.

so, the 5000ft were climbed in 5000/(2x-10)

the number of hours it lasted climbing? well, simply add them up.

Answer: The expression that represents the number of hours the mountaineer climbed is given by

[tex]\dfrac{1000}{x}+\dfrac{2500}{x-5}[/tex]

Step-by-step explanation:

Since we have given that

Distance covered by mountaineer = 1000 feet

Speed at which he climbed = x feet per hour

Time taken by him would be

[tex]\dfrac{1000}{x}[/tex]

Additional distance covered by him = 5000 feet

Speed at which he climbed this time = 2x-10

So, Time taken is given by

[tex]\dfrac{5000}{2x-10}\\\\\\=\dfrac{5000}{2(x-5)}\\\\\\=\dfrac{2500}{x-5}[/tex]

Hence, the expression that represents the number of hours the mountaineer climbed is given by

[tex]\dfrac{1000}{x}+\dfrac{2500}{x-5}[/tex]

The scores on a final exam were approximately normally distributed with a mean of 82 and a standard deviation of 11. If 85 students took the exam, and above a 60 is a passing grade, how many students failed the exam?

Answers

In this case, we can use the z statistic to find for the proportion of students who failed the exam. The formula for z score is given as:

t = (x – u) / s

where,

x = the sample score = 60

u = sample score mean = 82

s = standard deviation = 11

Substituting all given values into the equation:

t = (60 – 82) / 11

t = - 2

Based from the standard proportion distribution tables for z, this corresponds to:

P = 0.0228

This means that 2.28% of the students failed the exam or equivalent to:

failed students = (0.0228) * 85 = 1.938

approximately 2 students failed the exam

If p is a positive integer,then p(p+1)(p-1) is always divisible by?

Answers

I am not quite sure what the choices are, but the answer to that problem is:

If p is a positive integer, then p(p+1)(p-1) is always divisible by “an even number”.

The explanation to this is that whatever number you input to that equation, the answer will always be an even number. This is due to the expression p(p+1)(p-1) which always result in a even product.

For example if p=3, then (p+1)(p-1) becomes (4)(2) giving you a even number.

And if for example if p=2, then (p+1)(p-1) becomes (3)(1) which gives an odd product, but we still have to multiply this with p therefore 2*3 = 6 which is even product. The outcome is always even number.

Answer: From the choices, select the even number

Final answer:

If p is a positive integer, p(p+1)(p-1) is always divisible by 3.

Explanation:

If p is a positive integer, then p(p+1)(p-1) is always divisible by 3.

This can be proven by applying the property of divisibility by 3. According to this property, a number is divisible by 3 if and only if the sum of its digits is divisible by 3.

In the expression p(p+1)(p-1), the three terms p, (p+1), and (p-1) represent three consecutive numbers. Since the sum of the digits of any consecutive numbers is always divisible by 3, the expression is always divisible by 3.

Susan invests
2
times as much money at

as she does at
4%
. If her total interest after
1
year is
$800
, how much does she have invested at each rate?

Answers

Let f=amount invested at 4% and e=amount invested at 8%

0.04f+.08e=800

However, e=2f so the above equation becomes:

0.04f+0.08(2f)=800

0.04f+0.16f=800

0.2f=800

f=$4000, since e=2f

e=$8000

So Susan invested $4000 at 4% and $8000 at 8%.

Final answer:

To find how much Susan has invested at each rate when she invests 2 times as much money at 8% as she does at 4%, create and solve an equation based on the total interest earned.

Explanation:

Susan has invested $x at 4% interest rate and $2x at 8% interest rate.

Given that the total interest after 1 year is $800, we can create the equation: $x(0.04) + $2x(0.08) = $800.

Solving the equation, we find that Susan has $3,000 invested at 4% and $6,000 invested at 8%.

x2 + 8x – 65 = 0
x2 + 8x – 81 = 0

Answers

Let x be the "enlargement value" of each side :
Then the enlarged side becomes (x+4) and the square = (x+4)²
The final area should be (x+4)² = 81
Let's expand:
x²+ 8x + 16 = 81
x² + 8x + 16 - 81 = 0
x² + 8x - 65 = 0

Answer:

[tex]x^2+8x-65=0[/tex]

Step-by-step explanation:

Side length of square = 4 inches

Let x be the increase in length

So, New length = x+4

Area of square = [tex]Side^2[/tex]

Area of enlarged square = [tex](x+4)^2[/tex]

Using identity : [tex](a+b)^2=a^2+b^2+2ab[/tex]

Area of enlarged square = [tex]x^2+16+8x[/tex]

We are given that The final area needs to be 81 square inches.

So, [tex]x^2+16+8x=81[/tex]

[tex]x^2+16+8x-81=0[/tex]

[tex]x^2+8x-65=0[/tex]

So, Option C is true

Hence equation can be used to solve for x, the increase in side length of the square in inches is [tex]x^2+8x-65=0[/tex]
