The graph of a quadratic function is shown. What is the equation of this function in f(x)=ax^2+bx+c​ form?

The probability of not throwing the ball to a receiver on either throw is 0.66, or 66%. 

Consider two conceivable scenarios for quarterback tosses.

1. He tosses the ball to the recipient on his to begin the endeavor.

2. He misses the collector on his to begin with endeavor and once more on his moment endeavor.

The likelihood of situation 1 is 1 – 0.4 = 0.6. Usually since the quarterback on the primary attempt he misses the collector 40% of the time.

The likelihood for Situation 2 can be calculated as

P(1st Endeavor Fizzled + 2nd Endeavor Fizzled) = P(1st Endeavor Fizzled) * P(2nd Endeavor Fizzled | 1st Endeavor Fizzled)

= 0.4 * 0.15 = 0.06

Subsequently, the likelihood of not tossing the ball to the recipient on any toss is the entirety of the probabilities of Scenarios 1 and 2.

P(Don't toss to recipient) = P(Scenario 1) + P(Scenario 2)

= 0.6 + 0.06

= 0.66

Hence, the likelihood of not tossing the ball to the collector on any toss is 0.66, or 66%.

Piece by piece :

Numerator            5^3 X 5^4  =   5 ^(3+4) = 5^7

Denominator        5^2 X 5^1   =   5^(2+1)   = 5^3

so now you have:

5^7 / 5^3       this equals    5 ^(7-3) = 5^4

then     (5^4 )^3  =  5^(4x3) = 5 ^12

The likelihood of the agent making 2 sales out of 8 appointments is 0.132.

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur.

The probability of making a sale on any appointment is 1/5, and the probability of not making a sale is 4/5.

We can use the binomial distribution to find the probability of making 2 sales out of 8 appointments

P(2 sales) = (8 choose 2) × (1/5)² × (4/5)⁶

where (8 choose 2) = 28 is the number of ways to choose 2 appointments out of 8.

So, plugging in the values, we get

P(2 sales) = 28 × (1/5)² × (4/5)⁶

= 0.132

We can use the inverse normal distribution function to find the z-score corresponding to the desired percentile, and then use the formula for standardizing a normal variable to find the corresponding raw score.

The score that separates the top 53% from the bottom 47% on an English test with a normal distribution, mean of 37.6, and standard deviation of 7.6 can be found using the inverse normal distribution function.

We need to find the z-score that corresponds to the 53rd percentile. We can do this using a standard normal distribution table or a calculator. The z-score corresponding to the 53rd percentile is approximately 0.07.

We can use the formula for standardizing a normal variable to find the corresponding raw score: z = (X - mean) / standard deviation Rearranging this formula, we get: X = z * standard deviation + mean

Plugging in the values we have: X = 0.07 * 7.6 + 37.6 X ≈ 38.2 A score of approximately 38.2 separates the top 53% from the bottom 47% on this English test.

Answer:

To find the equation for d, the distance in meters that Martin covers per second, we need to use the formula:

distance = speed × time

Here, the distance covered by Martin is 100 meters, and the time taken is 15 seconds. Therefore, we can write:

distance = speed × time

100 meters = speed × 15 seconds

To find the speed, we can rearrange the equation as:

speed = distance / time

speed = 100 meters / 15 seconds

So the speed of Martin is:

speed = 6.67 meters per second

Therefore, the correct equation for d, the distance in meters that Martin covers per second, is:

d = speed

d = 6.67 meters per second

Answer: There is no option that matches the correct equation for d, which is simply d = 6.67 meters per second.

Step-by-step explanation:

In direct variation, the relationship between two variables x and y can be represented by the equation y = kx, where k is the constant of variation.

To find the value of k, we can substitute the given values of x and y into the equation:

y = kx

12 = k(2)

Solving for k, we can divide both sides by 2:

k = 6

Now we can write the direct variation equation using the value of k:

y = 6x

Therefore, the direct variation equation that shows the relationship between x and y is y = 6x.

The given statement "To find the sample of a population it is always necessary to take into account all the information of the problem" is false because a sample can be selected using random sampling techniques that do not require knowledge of the entire population.

It is not always necessary to take into account all the information of the problem to find a sample of a population. In many cases, a sample can be selected using random sampling techniques that do not require knowledge of the entire population. However, it is important to ensure that the sample is representative of the population, and this often requires careful consideration of the characteristics of the population.

If the problem already has the population defined and we want to estimate a parameter such as the mean or proportion, we can use the formula that only involves the standard deviation of the population, known as the standard error. For example, if we want to estimate the mean of a population, we can use the formula

SE = σ / √n

Where SE is the standard error of the mean, σ is the standard deviation of the population, and n is the sample size. By calculating the standard error, we can then use it to construct confidence intervals and conduct hypothesis tests about the population mean.

However, it is important to note that in many cases we do not know the standard deviation of the population and need to estimate it from the sample. In such cases, we use the sample standard deviation as an estimate of the population standard deviation, and use a t-distribution instead of a normal distribution to construct confidence intervals and conduct hypothesis tests.

Approximate height to the statue's actual height of 120 feet, 3 inches from heel to top of head is 123.75 feet.

To estimate the height of the statue, the student can use the method of similar triangles. Since the length of the statue's right arm is 45 feet and the length of the student's right arm is 2 feet, the ratio of the lengths of the arms is 45/2 = 22.5. If we assume that the ratio of the heights of the statue and the student is also 22.5, then the height of the statue can be estimated as:

height of statue = height of student x ratio of heights

height of statue = 5.5 x 22.5

height of statue = 123.75 feet

This estimated height of the statue is close to the actual height of 120 feet, 3 inches. It should be noted that this method of estimation assumes that the ratio of the heights of the statue and the student is the same as the ratio of the lengths of their arms. This may not be completely accurate, as the proportions of the statue and the student may be different.

Reflexive Property

The reflexive property of equality in algebra asserts that a number is always equal to itself. Equality has a reflexive attribute. If an is a positive integer, then a = a.

When two parallel lines cross by any other line (i.e. the transversal), corresponding angles are generated in matching corners or corresponding angles with the transversal.

So in the above proof, ∠4 ≅ ∠1 ; ∠3≅∠2 because they are a pair of corresponding angels because they are created in matching corners.

The graph that can be used to approximate the number of years it will take for the plate's value to be $30 is given as follows:

First graph.

The exponential function giving the value of the plate after x years is given as follows:

f(x) = 18(1.05)^x.

The value of the plate will be of $30 when f(x) = 30, hence the time x is obtained as follows:

18(1.05)^x = 30

(1.05)^x = 30/18

(1.05)^x = 10/6

x = log(10/6)/log(1.05)

x = 10.47 years.
