The perimeter of a square field is 348 yards. How long is each side?
Answers
Answer:
87
Step-by-step explanation:
348 divided by 4
Answer:
87 yards
Step-by-step explanation:
Recall that the side lengths of a square are equal to each other, so the perimeter is 4x (where x is the length of each side).
So, since the perimeter of the square field is 348 yards, just divide 348 by 4 to get 87.
So, 87 yards is the length of each side.

The probability of drawing either a diamond or an ace from a deck of cards is \(\frac{4}{13}\).
We need to determine the favorable outcomes (cards that satisfy the conditions) and divide that number by the total number of possible outcomes in order to calculate the probability of drawing either a diamond or an ace from a regular 52-card deck of playing cards.
Number of aces in a deck = 4 (one for each suit: hearts, diamonds, clubs, and spades)
Number of diamonds in a deck = 13
One card, the Ace of Diamonds, is both a diamond and an ace, thus we must subtract it once from the total in order to prevent double counting.
Therefore, the favorable outcomes = 4 (number of aces) + 13 (number of diamonds) - 1 (Ace of Diamonds) = 16.
The total number of possible outcomes is 52 (the number of cards in a deck).
\(Probability = \frac{ Favorable \ outocomes}{Total\ number\ of\ possible\ outcomes} = \frac{16}{52} = \frac{4}{13}\)
Therefore, the probability of drawing either a diamond or an ace is 4/13 or approximately 0.3077, or 30.77%.

A quantity with an initial value of 480 grows exponentially at a rate such that the quantity doubles every 6 minutes. What is the value of the quantity after 0.2 hours, to the nearest hundredth?
answer 1920
Answers
The value of quantity after 0.2 hours is, 960
Given that;
A quantity with an initial value of 480 grows exponentially at a rate such that the quantity doubles every 6 minutes.
We know that;
The exponential growth function is
A = A₀ (1 + r)ⁿ
Where, A= The number of quantity after t days
A₀ = initial number of quantity
r = rate of growth
n = time in minutes
A quantity with an initial value of 830 grows at a rate such that the quantity doubles in 0.2 hours = 12 minutes
And, A = 2 x 480 = 960
A₀ = 480
n = 12 minutes
r = ?
⇒ A = A₀ (1 + r)ⁿ
⇒ 960 = 480 (1 + r)¹²
⇒ 2 = (1 + r)¹²
⇒ \(r = \sqrt[12]{2} - 1\)
Now, to find the quantity after 12 minutes, we plug A = 830, t = 12 minutes in exponential function;
⇒ A = A₀ (1 + r)ⁿ
⇒ \(A = 480 (1 + \sqrt[12]{2} - 1)^{12}\)
⇒ A = 480 (2)
⇒ A = 960

Given f(x)=2/x^2+3x-10, which of the following is true?
A. f(x) is positive for all x<-5
B. f(x) is negative for all x<-5
C. f(x) is positive for all x<2
D. f(x) is positive for all x>2
Answers
The only true statement about the domain of the given function is:
B. f(x) is negative for all x < -5
How to solve for the domain of the function?The domain of a function is defined as the set of values that we can possibly plug into our function. This set is the x values in a function such as f(x).
Now, we are given the function as:
f(x) = \(\frac{2}{x^{2} } + 3x - 10\)
When x < -5, we have:
f(-4) = \(\frac{2}{(-4)^{2} } + 3(-4) - 10\)
f(-4) = -21.875
This suggests that for all values below x = -5 will result in negative values
When x > 2
f(3) = \(\frac{2}{3^{2} } + 3(3) - 10\)
f(3) = -0.78
Thus, it will get positive for higher values but it can also be negative as seen here.

Answers
Answer:
f(2) = 0
Step-by-step explanation:
Given that f(x) = 3x² - 7x + 4/x ,
We want to find f(2)
To do so, we simply "plug in" or substitute the inputted value (which is 2) into all x's.
So
f(x) = 3x² - 7x + 4/x
==> replace all x's with 2
f(2) = 3(2)² - 7(2) + 4/2
==> evaluate exponent
f(2) = 3(4) - 7(2) + 4/2
==> multiply 3 and 4
f(2) = 12 - 7(2) + 4/2
==> multiply -7 and 2
f(2) = 12 - 14 + 4/2

f(2) = 12 - 14 + 2

Let (-3,-2) be a point on the terminal side of theta. Find the csc(theta)
Answers
The csc(theta) = 1/sin(theta) = 1/(-2/√13) = -√13/2. So, the cosecant of theta is -√13/2.
To find the cosecant (csc) of theta when a point (-3, -2) lies on its terminal side, we need to determine the hypotenuse (r) of the right triangle formed by this point.
Using the Pythagorean theorem, r^2 = (-3)^2 + (-2)^2. So, r^2 = 9 + 4 = 13, and r = √13.
The csc(theta) is the reciprocal of sin(theta). Sin(theta) is calculated as the ratio of the opposite side (y-coordinate) to the hypotenuse, or sin(theta) = -2/√13.

Activity trackers are electronic devices that people wear to record physical activity. Researchers wanted to estimate the mean number of steps taken on a typical workday for people working in New York City who wear such trackers. A random sample of 61 people working in New York City who wear an activity tracker was selected. The number of steps taken on a typical workday for each person in the sample was recorded. The mean was 9,797 steps and the standard deviation was 2,313 steps.
a. Construct and interpret a 99 percent confidence interval for the mean number of steps taken on a typical workday for all people working in New York City who wear an activity tracker.
b. A wellness director at a company in New York City wants to investigate whether it is unusual for one person working in the city who wears an activity tracker to record approximately 8,500 steps on a typical workday. Is it appropriate to use the confidence interval found in part (a) to conduct the investigation.
Answers
Answer:
a) The 99% confidence interval for the mean number of steps taken on a typical workday for all people working in New York City who wear an activity tracker is (9,009, 10,585).
We are 95% confident that the mean number of steps taken on a typical workday for all people working in New York City who wear an activity tracker is within 9,009 and 10,585 steps.
b) No, we can not use the confidence interval to estimate the probability of individual values. It can onlybe used to make inference about the population mean.
Step-by-step explanation:
a) We have to calculate a 99% confidence interval for the mean.
The population standard deviation is not known, so we have to estimate it from the sample standard deviation and use a t-students distribution to calculate the critical value.
The sample mean is M=9,797.
Ths sample standard deviation is s=2,313.
The sample size is N=61.
When σ is not known, s divided by the square root of N is used as an estimate of σM:
\(s_M=\dfrac{s}{\sqrt{N}}=\dfrac{2313}{\sqrt{61}}=\dfrac{2313}{7.81}=296.15\)
The degrees of freedom for this sample size are:
\(df=n-1=61-1=60\)
The t-value for a 99% confidence interval and 61 degrees of freedom is t=2.66.
The margin of error (MOE) can be calculated as:
\(MOE=t\cdot s_M=2.66 \cdot 296.15=787.84\)
Then, the lower and upper bounds of the confidence interval are:
\(LL=M-t \cdot s_M = 9797-787.84=9009\\\\UL=M+t \cdot s_M = 9797+787.84=10585\)
The 99% confidence interval for the mean number of steps taken on a typical workday for all people working in New York City who wear an activity tracker is (9,009, 10,585).
b) The value of 8,500 steps is outside the confidence interval, but this means that it is an unusual value for the mean number of steps for all people in New York City who wear an activity tracker.
We can not use the confidence interval to estimate the probability of individual values.
The activity tracking devices.
The activity tracker re those devices such as watches and a bands that tells you about your physical activity such as skipping, running, and walking. They simply count the steps and tell you about the daily goals and targets. They are quite effective for monitoring blood pressure and more.
Thus answer is 9,009, 10,585 workers, 9,009, and 10,585 steps and population mean.

The 95% confidence that the mean number of steps taken by workers of the City was within 9,009 and 10,585 steps.The confidence interval can be used to estimate the probability of the individual values.

Answers
The probability is P = 0.135
How to find the probability?
First, we need to find the individual probabilities, that are given by the quotient between the number of outcomes that meet the condition and the total number of outcomes.
P(head) = 1/2P(odd number) = 3/6 (there are 3 odd numbers on the dice)P(card greater than 6) = 28/52 (28 cards with numbers larger than 6).The joint probability is given by the product between the individual probabilities, so we get:
