What is the length of a garden hose that is stretched diagonally corner-to-corner across a yard that measures 72 meters long and 60 meters wide? Round to the nearest meter.
Here, we need to find the length of the hose which is diagonally placed in the rectangular garden.
The length is given as = 72 meters
The width is given as = 60 meters
We will use Pythagoras theorem here.
Hypotenuse² = Perpendicular² + Base²
Hypotenuse² = 72² + 60²
Hypotenuse² = √8,784 meters²
Hypotenuse = 93.72 meters
Thus, the length of diagonal hose will be = 93.72 meters

A ________ sample is a sample in which each member of the population has a known, nonzero, chance of being selected for the sample.
A random sample is a subset of a population where every individual has an equal and known chance of being selected, providing a representative segment for study.
A random sample is a sample in which each member of the population has a known, nonzero, chance of being selected for the sample. This means that in a random sample, every individual in the larger population has an equal opportunity to be included. There are various methods to achieve a random sample, such as simple random sampling, stratified sampling, or using random digit dialing. Random samples are crucial because they tend to be representative of the population, thereby allowing the results of studies to be generalizable.

Kevin and randy muise have a jar containing 68 coins, all of which are either quarters or nickels. the total value of the coins in the jar is $13.40. how many of each type of coin do they have?
Kevin and Randy have 50 quarters and 18 nickels.
Explanation:To solve this problem, we can set up a system of equations. Let's use the variables x for the number of quarters and y for the number of nickels. We can then write two equations based on the given information:
Equation 1: x + y = 68 (the total number of coins is 68)
Equation 2: 0.25x + 0.05y = 13.40 (the total value of the coins is $13.40).
We can start by solving Equation 1 for x in terms of y:
x = 68 - y. Now we can substitute this expression for x into Equation 2:
0.25(68 - y) + 0.05y = 13.40
Simplifying, we get 17 - 0.25y + 0.05y = 13.40.
Combining like terms, we have 0.20y = 3.60.
Dividing both sides by 0.20, we find y = 18. Plugging this value back into Equation 1, we can solve for x:
x + 18 = 68
x = 68 - 18 = 50.
Therefore, Kevin and Randy have 50 quarters and 18 nickels.

A ball is thrown downward from the top of a 190-foot building with an initial velocity of 21 feet per second. the height of the ball h after t seconds is given by the equation h equals negative 16 t squared minus 21 t plus 190. how long after the ball is thrown will it strike the ground?
The ball hits the ground after approximately 4.16 seconds.
To find the time at which the ball strikes the ground, we need to determine when h(t) = 0. Given the equation for height:
[tex]\[ h(t) = -16t^2 - 21t + 190 \][/tex]
we can set h(t) to 0 and solve for t:
[tex]\[ -16t^2 - 21t + 190 = 0 \][/tex]
Using the quadratic formula, we can find the roots of this equation:
[tex]\[ t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]
where a = -16 , b = -21, and c = 190. Plugging in the values, we get:
1. Find the discriminating value [tex]\( \Delta = b^2 - 4 \times a \times c \)[/tex]:
[tex]\[ \Delta = (-21)^2 - 4 \times (-16) \times 190 = 441 + 12160 = 12601 \][/tex]
2. Calculate the roots:
[tex]\[ t = \frac{-(-21) \pm \sqrt{12601}}{2 \times -16} \\ \[ t = \frac{21 \pm \sqrt{12601}}{-32} \][/tex]
Since we're interested in the positive value (representing the time when the ball hits the ground), we'll only consider the root with the "minus" sign:
[tex]\[ t = \frac{21 - \sqrt{12601}}{-32} \approx \frac{-21 + \sqrt{12601}}{32} \approx \frac{21 - \sqrt{12601}}{32} \][/tex]
Using a calculator, let's approximate the result:
[tex]1. Compute \( \sqrt{12601} \approx 112.24 \),\\2. Then calculate \( 21 + 112.24 \approx 133.24 \),\\3. Divide by 32 to get \( t \approx \frac{133.24}{32} \approx 4.16375 \).[/tex]
Rounding to a more readable result, we can say that the ball hits the ground after approximately 4.16 seconds.

a man made lake is stocked with 10,000 fish. This population is expected to decline by an annual rate of 15%. Predict the fish population 5 years after the lake is stocked
The population will be approximately 4,437 fish after 5 years.
To predict the fish population 5 years after the lake is stocked,
We can use the formula for exponential decay:
[tex]\[ P = P_0 \times (1 - r)^t \][/tex]
Where:
P is the final population[tex]\( P_0 \)[/tex] is the initial populationr is the annual rate of decline (expressed as a decimal)t is the number of yearsGiven:
[tex]\( P_0[/tex] = 10,000 (initial population)r = 0.15 (annual rate of decline, expressed as 15% or 0.15)t = 5 (number of years)Substituting the values into the formula:
[tex]\[ P = 10,000 \times (1 - 0.15)^5 \][/tex]
[tex]\[ P = 10,000 \times (0.85)^5 \][/tex]
Calculating:
P ≈ 10,000 × 0.443705
P ≈ 4437.05
So, the fish population 5 years after the lake is stocked is approximately 4437 fish.

Suppose 20 rabbits are taken to an island. the rabbit population then triples every year. the function f(x)
This question is about exponential growth and the rabbit population on an island.
Explanation:The subject of this question is Mathematics. Specifically, it involves exponential growth and a function that represents the rabbit population on the island over time. Let's define the function f(x) to represent the population of rabbits at year x.
Based on the information given, the initial population is 20 rabbits. The population triples every year, which means that for each year x, the population is f(x) = 20 * 3^x.
For example, after 1 year, the population would be f(1) = 20 * 3^1 = 60 rabbits. After 2 years, the population would be f(2) = 20 * 3^2 = 180 rabbits, and so on.

The measure of arc QS is (4x – 18)°.
What is the value of x?
40.5

94.5
180
ANSWER IS 49.5
Answer:
Option B. 49.5 degrees
Step-by-step explanation:
Given that arc QS measures 4x-18
Arc QS is a semicircle and hence subtended angle by semicircle at the centre is 180 degrees.
Use this to find the value of x
4x-18 = 180 degrees
Add 18 to both sides
4x=198
Divide by 4
x =198/4 =49.5
