Player A is the most consistent, with a range of 7.
Player B is the most consistent, with a range of 5.

Answer:

169

Step-by-step explanation:

Given data

The function is

5x^2+7x=6​

rearrange

5x2+7x-6=0

From the above expression, we can see that

a=​5

b=7

c=-6

Substitute into the expression b^2-4ac

=7^2-4*5*-6

= 49-(-120)

=49+120

=169

Hence the answer is 169

Answer:

Liam reads 52.5 pages in 6 hours

Step-by-step explanation:

to solve this problem you need to start with finding how many pages he reads in 1 hour.

to do this, divide 35 by 4.

35/4 = 8.75

the unit rate is 8.75 pages per hour.

now just multiply the unit rate by the amount of hours.

8.75 * 6 = 52.5

Considering the vertex of a quadratic equation, the greatest rectangular area that the farmer can enclose with 100 m is of 625 m².

A quadratic equation is modeled by the rule presented as follows:

y = ax^2 + bx + c

The vertex has these following coordinates.

\((x_v, y_v)\)

In which:

Considering the coefficient a, we have that the vertex can represent either a maximum or a minimum point in the function, as follows::

In this problem, the coefficients of the quadratic equation representing the area are given as follows:

a = -1, b = 50.

The greatest rectangular area that the farmer can enclose with 100 m is the y-coordinate of the vertex of the quadratic equation, hence:

\(y_v = -\frac{50^2 - 4(-1)(0)}{4(-1)} = 625\)

The area is of 625 m².

The quadratic equation for the area is:

A(w) = -w² + 50w

\(x_1+x_2=6x_1x_2\)

We're going to use Vieta's formula to solve the problem.

\(x_1+x_2=-\dfrac{b}{a}\\\\x_1x_2=\dfrac{c}{a}\)

Therefore

\(x_1+x_2=-\dfrac{-3}{2}=\dfrac{3}{2}\\\\x_1x_2=\dfrac{4m}{2}=2m\)

And so

\(\dfrac{3}{2}=6\cdot2m\\\\4m=\dfrac{1}{2}\\\\m=\dfrac{1}{8}\)

It will take approximately 325.14 minutes (or 5 hours and 25 minutes) for the airplane to reach an altitude of 5 miles.

We can start by using trigonometry to determine the vertical component of the airplane's velocity, which will tell us how fast it is climbing. Since the angle of climb is 10 degrees, we can use the sine function:

sin(10) = opposite/hypotenuse

vertical velocity = hypotenuse * sin(10)

The hypotenuse is the airplane's speed of 400 mph, so we have:

vertical velocity = 400 * sin(10) ≈ 69.28 mph

To find how long it takes the airplane to reach an altitude of 5 miles, we need to convert 5 miles to feet (since velocity is given in miles per hour):

5 miles * 5280 feet/mile = 26,400 feet

Now we can use the formula:

time = distance/velocity

where distance is the altitude we want to reach (26,400 feet) and velocity is the vertical component of velocity (69.28 mph). However, we need to convert velocity to feet per minute to match the units of distance and get the time in minutes:

69.28 mph * 5280 feet/mile * 1/60 min/hour ≈ 81.22 feet/min

Now we can calculate the time:

time = 26,400 feet / 81.22 feet/min ≈ 325.14 min

Based on the given information, we can perform a one-sample t-test to determine if there is sufficient evidence to support the claim that the chocolate chip bags are underfilled.

The null hypothesis (H0) states that the mean weight of the bags is equal to 416 grams, while the alternative hypothesis (H1) states that the mean weight is less than 416 grams.

Given the sample mean of 412 grams, standard deviation of 11 grams, and a sample size of 12 bags, we can calculate the t-statistic using the formula: t = (sample mean - population mean) / (standard deviation / √sample size).

The critical t-value for a one-tailed test at a 0.1 level of significance and 11 degrees of freedom (n-1) can be found in a t-distribution table. Comparing the calculated t-statistic to the critical t-value will help us determine whether to accept or reject the null hypothesis.

If the calculated t-statistic is less than the critical t-value, we reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the bags are underfilled at the 416-gram setting. If the t-statistic is greater than or equal to the critical t-value, we fail to reject the null hypothesis and cannot conclude that the bags are underfilled.

Remember to always consider the level of significance and the assumptions of the test (such as normality) when interpreting the results of a statistical hypothesis test.

Solution:

Given:

The graph of g(x) is shown;

From the graph of g(x), the horizontal asymptote is y = 0

Therefore, OPTION C is correct

The form:

y = a(x-h)^2 + k

Is the vertex form of the quadratic equation, by finding the vertex, we conclude that k = -1.

For any quadratic equation of the form:

y = a*x^2 + b*x + c

With a vertex (h, k), we can rewrite the equation as:

y = a*(x - h)^2 + k

And the value h of the vertex is given by:

h = -b/(2a)

In this case, the quadratic equation is:

y = 2x^2 - 8x + 7

Then the value h of the vertex is:

h = -(-8)/(2*2) = 2

Evaluating the quadratic equation in x = 2 we will get the value of k, so we have.

y = 2*(2)^2 - 8*2 + 7 = -1

Then the vertex is (2, -1), which means that the value of K is -1.

Answer:

Probability = 0.13591

Step-by-step explanation:

We are given;

Population mean; μ = 4.55

Population standard deviation: σ = 0.39

Now, we want to find the probability that the housefly's wing length will meet the requirements of the first phase of the experiment. This is;

P(3.77mm < X < 4.16mm)

Z-score formula is;

z = (x - μ)/σ

When x = 3.77mm

z = (3.77 - 4.55)/0.39

z = -2

When x = 4.16

z = (4.16 - 4.55)/0.39

z = -1

From online p-value calculator between 2 z-scores attached, we have;

P-value = 0.13591

From the graph of miles driven and pricing, it can be observed that for 200 miles option A price is $100 and option B price is $70.

So option A cost more than option B.

Determine the difference between $100 and $70 to obtain how much option A cost more than option B.

So option A cost $30 more than option B.

From the graph, it can be observed that lines of option A and option B intersect each other at (50,40). So option A and option B cost same for 50 miles.

To determine the necessary sample size to obtain an interval width of 50 ppm for a confidence level of 95%, we need to use the formula for sample size calculation for estimating a population mean.

The formula for sample size calculation is:

n = (Z * σ / E)^2

In this case, the desired margin of error is 50 ppm, which means the interval width is 2 * E = 50 ppm. Therefore, E = 25 ppm.

The Z-score corresponding to a 95% confidence level is approximately 1.96.

Given that the investigators made a rough guess of 175 for the value of σ (standard deviation) before collecting data.

We can substitute these values into the sample size formula:

n = (1.96 * 175 / 25)^2

Simplifying the calculation:

n = (7 * 175)^2

n = 1225^2

n ≈ 1,500,625

Therefore, a sample size of approximately 1,500,625 would be necessary to obtain an interval width of 50 ppm for a confidence level of 95%.

To obtain an interval width of 50 ppm with a confidence level of 95%, a sample size of approximately 1,500,625 is required. This is calculated using the formula for sample size estimation, considering a desired margin of error of 25 ppm and a standard deviation estimate of 175. The Z-score corresponding to a 95% confidence level is used to determine the sample size.

When we evaluate the quotient functions, (mn)(x) for x = -3

(mn)(-3) = 9 and (m/n) (x), x ≠ 0

To evaluate the quotient function (mn)(x) for x = -3, we  substituting x = -3 into the function mn(x).

This gives us (mn)(-3) = m(-3) × n(-3) = (-3)² × (-3) = 9.

We then need to evaluate (m/n)(x), x ≠ 0.

This is done by dividing the function m(x) by the function n(x). This gives us (m/n)(x) = m(x) / n(x) = x^2 / x = x. However, this expression is undefined when x = 0, because division by zero is undefine

When both groups are shifted to a situation in which they earn an alternative reward after being trained to navigate a runway for food, the group that received three food pellets will continue to perform the task at a high level while the group that received one food pellet will experience difficulty.

It is known that rats have a natural preference for higher rewards. As a result, the group that received three pellets will be more motivated to complete the task since they have already tasted a higher reward. Therefore, they will continue to perform at a high level in the new environment.

On the other hand, the group that received only one pellet may find it challenging to adapt to the new situation since they are now receiving a lower reward. As a result, they may struggle to complete the task, and their performance may decrease.

In conclusion, the group that received three pellets will perform better than the group that received one pellet when both groups are shifted to a situation in which they earn an alternative reward. This is because the rats have a natural preference for higher rewards.
