The time at which the football is 25 feet above the ground is 1/2 seconds and 21/8 seconds.

Given that:-

\(s(t) = -16t^2 + 50t + 4\)

Where s(t) represents the distance traveled by the football after t seconds.

We have to find the time at which the football is 25 feet above the ground.

Putting s (t) = 25 feet, we get,

\(25 = -16t^2 + 50t + 4\\\\ -16t^2 + 50t -21=0\\\\ 16t^2 - 50t - 21=0\)

Using middle term split theorem to solve the equation, we get,

\(16t^2 -42t -8t+ 21=0\)

2t(8t - 21) -(8t-21) = 0

(8t - 21)(2t - 1) = 0

t = 21/8 and 1/2 seconds.

Hence, the time at which the football is 25 feet above the ground is 1/2 seconds and 21/8 seconds.

Based on the results of the linearhypothesis function, we can conclude whether the hypothesis in part (b) is supported or not.

Linear hypothesis is a method of testing statistical hypotheses by estimating the parameters of a linear equation. This method of testing hypotheses involves estimating the parameters of a linear equation using a sample of data to determine if the parameters differ significantly from zero.

We can estimate the given model using the data in vote1. To do this, we will fit a linear regression model with the two independent variables (a's expenditures and b's expenditures) and the dependent variable (outcome). We can then use the model to determine whether a's expenditures have an effect on the outcome. We can do this by testing whether the coefficient for a's expenditures is statistically significant. If the coefficient is not statistically significant, then this means that a's expenditures do not have an effect on the outcome. We can also use the model to determine whether b's expenditures have an effect on the outcome. We can do this by testing whether the coefficient for b's expenditures is statistically significant. If the coefficient is not statistically significant, then this means that b's expenditures do not have an effect on the outcome. These results can be used to test the hypothesis in part (b). We can use the linearhypothesis function to test the hypothesis at a 5% significance level. If the test is found to be statistically significant, then this means that the hypothesis is supported. If the test is not statistically significant, then this means that the hypothesis is not supported.  Based on the results of the linearhypothesis function, we can conclude whether the hypothesis in part (b) is supported or not.

4s2 4p1 - electronic configuration corresponds to gallium

Periodic table has 4 different blocks, which are s block, d block, p block, and f block. Each block has corresponding elements which gives its electron configuration

What is group and period?

Prediction of Period ⟶ In electronic configuration of an atom, principal quantum number (n) of valence electrons represents the period of an element.

Prediction of Block ⟶ The orbital out of s,p,d and f which receives last electron represents block of an element

Prediction of Group ⟶ The group prediction occurs with help of block as:-

(1) For s block: Group Number = Number of valence e-

(2) For d block: Group Number = Number of e- in (n−1)d subshell + number of e- in ns subshell

(3) For p block: Group Number = Number of valence

e- + 10

(4) For f-block: Group Number = 3

Lets take an ex of chlorine ( Z= 17 )

Electronic configuration = 1s2 2s2 2p6 3s2 3p5

Since the last e- enters in p - subshell:

(i) Therefore Block will be "p "

(ii) For group we have element in p-block

∴ Group number = 10 + Valence e- in s subshell + Valence e- in p subshell

Group Number = 10+2+5=17

(iii) For period

Quantum number of valence e- =3

It is not appropriate to compare two means at a time in the way described. This would inflate the overall Type I Error and is a 'Multiple Testing' problem. The one-way ANOVA controls for the Type I Error and should be used instead. Comparing multiple pairs of means using independent two-sample t-tests without adjusting for the multiple comparisons can lead to an increased probability of committing a Type I error.

When comparing three or more populations means within a set of quantitative data that is categorized according to one factor/treatment, it is appropriate to use a one-way ANOVA instead of multiple independent two-sample t-tests. The reason is that performing multiple t-tests increases the overall Type I error rate, which is the probability of falsely rejecting a true null hypothesis. This is known as the multiple testing problem, and it occurs when we conduct multiple hypothesis tests without controlling the overall error rate.

In contrast, the one-way ANOVA controls for the Type I error rate and tests the null hypothesis that all population means are equal. If the null hypothesis is rejected, then at least one population mean is significantly different from the others. We can then perform post-hoc tests, such as Tukey's HSD, to determine which population means are different.

The correct answer is option c) The researcher did not label the participants with numbers before placing the numbers in a hat. The volunteers should have been randomly allocated into the treatment group and the control group by the researcher.

In math, random selection refers to the process of randomly selecting one or more elements from a set, with each element having an equal chance of being selected. The term "random sample" or "random subgroup" is frequently used to describe this. Consider selecting a sample of 3 at random from a collection of ten integers, 1, 2, 3, 4, 5, 6, 7, 8, or 10, for example.

Giving each component a distinct number and using a random number generator to choose three numbers from the range of 1 to 10 with replacement is one method to achieve this (meaning an element can be chosen more than once). This would produce a random selection of, say, 5.givenThe choice of a control group is the step that is absent from the researcher's procedure.

Using a good randomization technique, the researcher chose the intervention group by placing enumerated slips of paper in some kind of hat and randomly choosing half of the numbers.

To evaluate the outcomes with the treatment group, the investigation should have a sample size that doesn't receive the treatment.

The instruments of observation, experimentation, and conclusion are essential components of the scientific method.

In this instance, the volunteers should have been randomly split into the treatment group and the control group.

Let the number be y;

From the question, we can derive the below eaquation;

Let's go ahead and solve for y;

So, the number is 30.

The values of W and X that make NOPQ a parallelogram are:

W = -5w + 11

X = 3x

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size.

To determine the values of W and X that make NOPQ a parallelogram, we need to find the conditions under which the opposite sides of the quadrilateral are parallel.

The coordinates of the points N, O, P, and Q are given as follows:

N: (w+7, 5w-5)

O: (3/2x, 3)

P: (?, ?)

Q: (?, ?)

For NOPQ to be a parallelogram, the vector from N to O should be equal to the vector from P to Q, and the vector from O to P should be equal to the vector from Q to N.

The vector from N to O is:

NO = (3/2x - (w+7), 3 - (5w-5))

   = (3/2x - w - 7, -5w + 8)

The vector from O to P should be equal to the vector from Q to N. Thus:

OP = (P_x - (3/2x), P_y - 3)

QN = ((w+7) - Q_x, (5w-5) - Q_y)

Equating the corresponding components, we get the following equations:

3/2x - w - 7 = P_x - (3/2x)

-5w + 8 = P_y - 3

w + 7 = (w+7) - Q_x

5w - 5 = (5w-5) - Q_y

Simplifying these equations, we find:

P_x = 3x

P_y = -5w + 11

Q_x = w + 7

Q_y = 5w

Therefore, the values of W and X that make NOPQ a parallelogram are:

W = -5w + 11

X = 3x

The length of each arc intercepted by each slice is 2.09 inches.

The area of each slice 18.85 square inches .

To find the length of each arc intercepted by each slice and the area of each slice of a pizza that is 12 inches in diameter, follow the steps below. Length of each arc intercepted by each slice

The formula to find the length of each arc is given by:

L = θ/360 * 2πr

WhereL = length of arc

θ = angle of arc in degrees

r = radius of circle (diameter/2)

Given, diameter of pizza = 12 inches

So, radius of pizza = 12/2 = 6 inches

Since the pizza is cut into 6 equal slices, each slice will have an angle of 360/6 = 60 degrees.

Now, substituting the given values in the formula:

L = 60/360 * 2π* 6L = 1/6 * 12πL = 2π/3 ≈ 2.09 inches

The formula to find the area of each slice is given by:

A = θ/360 * πr²

Given, diameter of pizza = 12 inches

So, radius of pizza = 12/2 = 6 inches

Since the pizza is cut into 6 equal slices, each slice will have an angle of 360/6 = 60 degrees.

Now, substituting the given values in the formula:

A = 60/360 * π* 6²A = 1/6 * 36π

A = 6π ≈ 18.85 square inches

Thus, the length of each arc intercepted by each slice is approximately 2.09 inches and the area of each slice is approximately 18.85 square inches.

Complex numbers are those that expand on the idea of real numbers by incorporating an illogical element.

The formula for a complex number is "a + bi," where "a" and "b" are real numbers and "i" is the imaginary unit, which is equal to the square root of -1.

"A" stands for the complex number's real component, and "b" stands for the imaginary component.

We multiply the magnitudes of two complex numbers and add their arguments to determine their product.

Let's compute z₁z₂ with the supplied values.

Given:

z₁ = 8(cos 45° + isin 45°)

z₂ = 4(cos 210° + isin 210°)

We add the arguments and multiply the magnitudes to find z₁z₂:

Magnitude of z₁ = 8

Magnitude of z₂ = 4

Argument of z₁ = 45°

Argument of z₂ = 210°

Now, let's calculate z₁z₂:

Magnitude of z₁z₂ = (Magnitude of z₁) × (Magnitude of z₂) = 8 × 4 = 32

Argument of z₁z₂ = (Argument of z₁) + (Argument of z₂) = 45° + 210° = 255°

6/7 divided by 2/9 equals 3 6/7 I think.

Step-by-step explanation:

Answer:

7.27

Step-by-step explanation:

To make it easier to divide fractions, you multiply them by switching the second fraction around: 6/7 => 7/6

Then you switch the division symbol to a multiplication symbol.

Then you multiply the top numbers of the fractions first:

2 x 7 = 14

Then the bottom numbers:

9 x 6 = 54

So the fraction you end up with is 14/54.

Then you reduce by finding the GCF and dividing both numbers by that number. (The GCF is the greatest common factor that both numbers have, which is the highest number that is divisible by both numbers - an example would be the GCF of 6 and 9, which would be 3.)

The GCF of 14 and 54 is 2. Therefore, we divide 14 by 2 which would be 7. Then we divide 54 by 2, which would be 27. Since 7 and 27 do not have a GCF;

7/27 is the reduced form
