The water is given on alternate days.

According to the explanation given in the question, the Saharan islands make strong efforts to conserve their water resources. Part of these efforts includes not wasting water on plants that don't require it. Sometimes, we overwater plants, and the extra water simply evaporates into the atmosphere.

Palm trees, on the other hand, only require watering every other day, which is why they are only watered on alternate days. The precise amount of water provided to each tree in a real-world oasis would depend on a number of variables, including the age and health of the tree, the climate, and the availability of water. However, this is a hypothetical situation.

On solving the provide question, we can say that by linear equation the value  2000 times

A linear equation is one that has the form y=mx+b in algebra. B is the slope, and m is the y-intercept. It's usual to refer to the previous clause as a "linear equation with two variables" because y and x are variables. The two-variable linear equations known as bivariate linear equations. There are several instances of linear equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. It is referred to as being linear when an equation has the form y=mx+b, where m stands for the slope and b for the y-intercept.When an equation has the formula y=mx+b, with m denoting the slope and b the y-intercept, it is referred to as being linear.

Anton needs 3.75 lbs of sugar and 1.25 lbs of water to make 5 lbs of 75% sugar syrup.

To make a 75% sugar syrup, Anton will need 75% sugar and 25% water by weight. To find out how much sugar and how much water he needs, we can use the following formulas:

Sugar weight = 5lbs x 75% = 3.75lbs

Water weight = 5lbs x 25% = 1.25lbs

So Anton needs 3.75 lbs of sugar and 1.25 lbs of water to make 5 lbs of 75% sugar syrup.

It's important to note that syrup with 75% sugar content is heavy syrup, it is mostly used for preservation and not as a sweetener.

The probability of selecting a red or a blue tile from one of the bags is 1. This can be calculated by adding the probability of selecting a red tile (6/10) and the probability of selecting a blue tile (4/10) together. The equation for this is P(Red or Blue) = P(Red) + P(Blue), which simplifies to 10/10, or 1.

The probability of selecting either a red or blue tile from one of the bags can be calculated using the following equation:

P(Red or Blue) = P(Red) + P(Blue)

where P(Red) is the probability of selecting a red tile and P(Blue) is the probability of selecting a blue tile.

In this case, P(Red) = 4/10 and P(Blue) = 6/10. Therefore, the probability of selecting either a red or blue tile from one of the bags is:

probability of selecting

P(Red or Blue) = 4/10 + 6/10

P(Red or Blue) = 10/10

P(Red or Blue) = 1

If he left home 50 minutes before the class started he was 53.7 minutes late for his class.

Given that,

Speed of the bike = 16 feet per second = 10.9091 miles/hour

Distance from home to bus stop = 5 miles

Total time taken to reach bus stop = distance/ speed = 5 miles/10.9091 miles/hour= 0.458 hours = 27.5 minutes

Then, speed of the bus = 25 miles per hour

Distance from bus stop to campus = 25 miles

Total time taken to reach campus = distance/ speed = 25 miles/25 miles/hour= 1 hour= 60 minutes

Then, speed of the bike = 16 feet per second = 10.9091 miles/hour

Distance from campus to bike rack = 480 yards =  0.2727 miles

Total time taken to reach bike rack = distance/ speed = 0.2727 miles/ 10.9091 miles/hour= 0.249 hour= 15 minutes (approximately)

Then, the Speed of walking = 2.5 miles per hour

Distance from bike rack to class = 250 feet =  0.047 miles

Total time taken to reach class = distance/ speed = 0.047 miles/ 2.5 miles/hour= 0.0188 hour= 1.2 minutes (approximately)

Thus, total time taken to reach class = 27.5 minutes+60 minutes+15 minutes+1.2 minutes = 103.7 minutes

A measure of energy or work that is equivalent to the work completed by a force of one newton moving through a distance of one meter The term "joule" is frequently used in the context of physics to refer to units of energy.

                     Lifting an apple, which weighs roughly one Newton, is one example used to demonstrate a joule. One joule of work is expended if you lift the apple one meter into the air.

The conversion used from Joules to Btu is:

1 Btu = 1055.06 J

or,

 1J = 1/1055.06  Btu

 given that the energy 57281 J. Now we have to determine the energy in Btu.

General tables and summary tables are the two broad types into which statistical tables can be divided.

General tables

General tables include a compilation of specific data that is all pertinent to the topic or theme. Such tables are typically included in the appendices of reports and serve the primary function of assembling all the information on a given issue for quick reference.

Summery tables

Summary tables are made to accomplish a number of distinct tasks. They are typically included into the text, smaller in size than regular tables, and focus on a particular component of the data. Because they are generated from the general tables, the summary tables are also known as derivative tables. The data in the summary table is intended for analysis and inference.

Step-by-step explanation:

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x represent the other leg , then

x² + 13² = 15²

x² + 169 = 225 ( subtract 169 from both sides )

Answer: The height of an object can be determined using the relationship between the height of an object, the length of its shadow, and the length of a reference shadow. This relationship is given by the formula:

Height of object = (Height of reference object x Length of object's shadow) / Length of reference shadow

Given that a 4-ft vertical post casts a 10-in shadow at the same time a nearby cell phone tower casts a 125-ft shadow, we can use this formula to find the height of the cell phone tower:

Height of the cell phone tower = (4 ft x 10 in) / 125 ft

To find the height of the cell phone tower, we have to convert the 10 inches to feet, since the reference object's height is in feet.

10 inches = 10/12 ft = 5/6 ft

Height of the cell phone tower = (4 ft x 5/6 ft) / 125 ft

Height of the cell phone tower = 20/125 ft = 16/125 ft = 128/1025 ft = 128/1025 * 12/12 in = 128/85 ft

So the cell phone tower is 128/85 ft or (128/85) * 12 = 128/7 ft = 18.285714 ft tall.

The cell phone tower's height is 18.285714 ft.

Step-by-step explanation:

The probability that the veterinarian will conclude that the h6n2 virus is not present in the flock is 0.988

Since there are only two possible outcomes for this problem—that the bird is infected or not—the probability of a binomial distribution is involved.

Let's now assume that in this case, x represents a random variable that represents the number of afflicted chickens.

P(false positive test)=0.05, suggests that.

False positive tests indicate that the bird is not infected but the veterinarian still reports that it is. P(false negative test)=0.10 where.

False negative results indicate that the bird is infected even though the veterinarian says it is not.

Then, P(bird tested false positive) = 1-0.05=0.95 and P(bird is not infected) = 1.

Similar to that, P(bird tested false negative) = 1 - P(bird tested positive) 1- 0.10=0.90

Now, according to the question, the flock is considered contaminated if at least three out of every ten chickens are infected.

Therefore, i, if the veterinarian does not declare the birds as infected, it merely signifies that less than 3 birds are infected.

P(vet declares uninfected) then equals P(x=0) + P(x=1) + P(x=2)

P= (0.05)⁰ (0.95¹⁰) + (0.05)¹ (0.95)⁹ +(0.05)² (0.95)⁸ = 0.988

This is calculated, and the result is 0.988.
