Answers

Answer 1

On solving the provided question, we can say that here, in equation the greatest distance the ball is from the ground is -y = -4.9 + 9.8 +2 = 6.9

What is equation?

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

here,

the equation y=-4.9x^2+9.8x+2

where y = the distance the ball is from the ground in meters

x = the elapsed time in seconds

the greatest distance the ball is from the ground is -

[tex]y=-4.9x^2+9.8x+2[/tex]

x = 1

y = -4.9 + 9.8 +2 = 6.9

In certain areas the water is so scarce that every attempt is made to conserve it. For instance, on one oasis in the Sahara Desert, the amount of water necessary for each date palm is carefully determined. How much water is each tree given?

Answers

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.

So on solving the provided question we can say we can plotting data by x = 0.83; y = 0.79; z = 0.83

what is plotting data?

The most typical approach to display data using a chart is a graph that shows the relationship between two additional variables. Diagrams created by hand or on a computer are also acceptable. Move 2 units to the right after starting at the origin before going 3 units up. The coordinates for the points 2, 3, should be shown on the coordinate plane. Clearly state your points. The pink dot with the letter P thus stands for 2.3. Before creating a line chart, you need first generate a number line for each value in your data collection. Put an X (or dot) over each value of the data on the number line after that. For each instance when a value appears in a record, place an X over the corresponding number.

to get to campus, a student rides his bike at 16 feet per second for 5 miles to the bus stop. they place their bike on the bus and ride 15 miles at 25 miles per hour. they then ride their bike at 16 feet per second for 480 yards to the bike rack. they then walk 250 feet at 2.5 miles per hour into their class. if they left home 50 minutes before class started, how late/early were they? round to three significant figures and enter your answer as a positive value.

Answers

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

If 35% of a number is 77 and 90% of the same number is 198, find 55% of that number.

Answers

Answer:

Let's call the number we're trying to find "x".

We know that 35% of x is 77, so we can set up the equation:

0.35x = 77

We also know that 90% of x is 198, so we can set up another equation:

0.9x = 198

We can use the first equation to find the value of x and then substitute that value into the second equation to find 55% of x.

To find x, we divide both sides of the first equation by 0.35:

x = 77 / 0.35 = 220

Now that we know x is 220, we can find 55% of x by multiplying 220 by 0.55:

0.55x = 220 * 0.55 = 121

So 55% of the number is 121.

Answer:

121

Step-by-step explanation:

Because one of the answers is already divisible by 10, allowing us to find 100% of the unknown number, we can first find 10% by dividing the 90% number by 9. 198/9 is 22, meaning 22 is 10% of the number. We can then multiply it by 10 to get 100%, 22(10)=220. Meaning our full number is 220

From here we can simply multiply by our desired percentage, which is 55%. In order to multiply by a percent, you have you divide the percent by 100 to get .55. From there you can do 220*.55= 121. Meaning our answer is 121.

Answers

The percentage of the 90 students on the Springfield High School varsity soccer team who are seniors is 31%.

What is the percentage?

The percentage is a portion of a whole number or value.

Using percentages is a way of expressing values compared to others in relative terms.

The percentage refers to the ratio, which is obtained as the quotient of a numerator and a denominator, which is then multiplied by 100.

The total number of students on the Springfield High School varsity soccer team = 90

The makeup of the soccer team = freshmen, sophomores, juniors, and seniors

The number of seniors on the soccer team = 28

The percentage of seniors on the soccer team = 31.11% (28/90 x 100)

Thus, we can conclude that about 31 percent of the soccer team consists of seniors.

10. what is the probability of selecting either a red or blue tile from one of the bags? show a mathematical equation to support your answer

Answers

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

This means that there is a 100% chance of selecting either a red or blue tile from one of the bags.

if no chicken in the flock is infected with the h6n2 virus, what is the probability that the veterinarian will conclude that the h6n2 virus is not present in the flock? show how you found your answer.

Answers

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.

x+ y = 65..................(1)

4x+ 2y = 170

2x + y = 85.....................(2)

Solving equation (1) and (2) we get

2x + 65 -x = 85

x = 20

and, y = 65- 20 = 45

Hence, the difference if of £25.

What does Jule mean?

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.

As,    1J = 1/1055.06  Btu

      57281J = 57281J/1J * 1/1055.06 Btu

              = 54.6 Btu

Therefore, the correct option is, (B) 54.3 Btu.

Answer: 54.3 Btus

Step-by-step explanation:

given the function h(x)=x^-10x+21 determine the average rate of change of the function over the intervals -1

Answers

Therefore , the solution of the given problem of function comes out to be A(x) = 23.

Describe Function.

The subject of mathematics includes quantities including their variations, equations and related structures, forms and their locations, and places where they can be found. The term "function" refers to the relationship between a group of inputs, of which each has an associated output. A  variable association between inputs and outcomes in which each input leads to a single, distinct result is known as a function. Each function is given a region and a require a small space, or scope.

Here,

As a result, h(x) = x2-10x+21 A(x) =y/x =-1 x 10 A(x)=?

A(x) = y/x =h(x-g)-h(x)/g

=> g = Xmax - Xmin

=> g = 10-(-1)

=> g = 10+1

=> g = 11.

A(x) =(x-11)

² - 10*(x − 11) + 21 − (x² - 10x+21) /11

=> A(x)= x²- 22x+121-10x + 110 + 21 - x² + 10x -21/11

=>A(x) =231 - 22x /11

=>A(x)= 11 * (21-2x)/11

A(x) = 21-2x.

x = Xmin => A(x) = 21-2 (−1)

=>A(x) = 21+ 2

=>A(x) = 23

Therefore , the solution of the given problem of function comes out to be A(x) = 23.
