if a t test yields p > 0.05 the null hypothesis would normally be option (A) accepted

The null hypothesis defined as the types of hypothesis that do not have any statistical significance exist in the given set of observation.

The p value is defined as the measurement that is used to validate the hypothesis using the observed data. The range of the p value varies from zero to one.  Zero means no chance and 1 means absolute certainty  

If a t test yields a p-value greater than 0.05, it means that there is insufficient evidence to reject the null hypothesis, and the results are not statistically significant. Therefore, the null hypothesis is accepted.

Therefore, the correct option is (A) accepted

Answer:

No, his answer is wrong. The first expression is equal to 1/25 while the second is equal to 625.

Step-by-step explanation:

Answer: 0.04166

Step-by-step explanation:

1.25+(-1/3) +(-7/8)

1.25 - 1/3 - 7/8

= -8/24 - 21/24

= -8 - 21/ 24

= -29/24

= 1.25 - 29/24

= 1.25 - 1.20833

= 0.04166

There are over 6 quadrillion ways to make starting hands for Derek, Margaret, and Lenny!

We can start by finding the number of ways to choose 7 cards out of the 52 for Derek, then the number of ways to choose 7 cards out of the remaining 45 for Margaret, and then the remaining cards (which will form Lenny's hand).

The number of ways to choose 7 cards out of 52 is:

C(52,7) = 133,784,560

Once Derek has his 7 cards, there are 45 cards remaining, so the number of ways to choose 7 cards for Margaret is:

C(45,7) = 45,379,620

Finally, Lenny gets the remaining cards, so there is only one way to choose his hand.

Therefore, the total number of ways to make starting hands for all three players is:

133,784,560 x 45,379,620 x 1 = 6,081,679,822,404,800

So there are over 6 quadrillion ways to make starting hands for Derek, Margaret, and Lenny!

Yes, it is possible to find a limit at a location where there is a hole in a graph , such as where a point has been removed or where a graph abruptly stops.

This is because the limit of a function is defined as the value that the function approaches as x approaches a given value. In the case of a hole in the graph, the limit is found by looking at the limit from the left, the limit from the right, and the general limit.

The limit from the left is the limit of the function as x approaches the hole from the left. The limit from the right is the limit of the function as x approaches the hole from the right. The general limit is the overall limit of the function at the point where the hole appears. By considering all of these limits, it is possible to determine the overall limit of the function at the point where the hole is present.

The probability that a  randomly selected point within the circle falls in the red square is approximately 64%.

To find the probability that a randomly selected point within the circle falls in the square, we need to compare the areas of the square and that of  the circle.

Area of the square is  8 x 8 = 64Units²

The area of the  circle can be found using the formula for the area of a circle.

A = πr²

⇒ π x (4 √2 )² = 32π units²

The  probability is then given by the ratio of the area of the square to the area of the circle

Probability = Area of  Square / Area of Circle

= 64 / (32 π)

= 2 / π

≈ 0.6366

Rounded to the nearest hundredth, the  the probability that a randomly selected  point within the circle falls in the red square is about 0.64 or 64%.

To arrive at this answer, we can substitute x=7 into the given function, f(x), and simplify:

f(7) = (7)^5 - 47(7)^3 - 16(7)^2 + 8(7) + 52

f(7) = 16,807 - 105,413 - 784 + 56 + 52

f(7) = -88,282

Therefore, the main answer is -4,648.

we used the given function and substituted x=7 into it to find the value of f(x) at that specific point. We simplified the expression by using the order of operations (PEMDAS) and combined like terms. The resulting value gave us the answer we were looking for.

by plugging in x=7 into the function f(x) = x^5 - 47x^3 - 16x^2 + 8x + 52, we found that f(7) = -88,282. Therefore, the main answer is -4,648.

Oliver is farther from the station.

Let's call the initial distance from the station for Oliver and Roel as d1 and d2, respectively. The Law of Cosines states:

d1^2 = 3^2 + 4^2 - 2 * 3 * 4 * cos(30°)

d2^2 = 3^2 + 4^2 - 2 * 3 * 4 * cos(40°)

By solving the above equations, we can determine the distances d1 and d2. The hiker who is farther from the station will have the larger value of d1 or d2.

In this case, it can be seen that d1 > d2, meaning Oliver is farther from the station than Roel.

This is because the angle of 30° is larger than the angle of 40°, so the cosine of 30° is smaller than the cosine of 40°.

Therefore, Oliver is farther from the station.

The rate equation for a chemical reaction is  the relationship between the rate of the reaction and the concentrations of the reactants. To write the rate equation for the given reaction: 2 NO(g) + O2(g) → 2 NO2(g)

We need to determine the order of the reaction with respect to each reactant. This is typically done experimentally by measuring the initial rate of the reaction under different reactant concentrations. Let's assume that the rate of the reaction is proportional to the concentration of NO raised to the power of x and the concentration of O2 raised to the power of y: Rate = k [NO]^x [O2]^y. The values of x and y can only be determined through experimental analysis. Additionally, k represents the rate constant, which depends on the temperature and presence of a catalyst.

Without further experimental data, the exact rate equation cannot be determined, and we cannot assign specific values to x, y, or k.

Answer:

1 lb expensive chocolate

2 lbs other chocolate

Step-by-step explanation:

let x = number of pounds of the expensive candy bars

let y = number of pounds of the other candy bars

here is the first equation:

(the expensive lbs + other lbs comes to a total of 3 lbs altogether)

x + y = 3

here is the second equation:

($6 per pound + $4.5 per pound = $15)

6x + 4.5y = 15

we can do substitution, elimination, or graph.

let's do elimination with these two equations:

x + y = 3  AND 6x + 4.5y = 15

Let's eliminate the variable x to find variable y, and then use what we found for variable y to find variable x.

Multiply (x + y = 3) with 6

Which looks like this: 6(x+y = 3)

And the above becomes 6x + 6y = 18

the equation x + y = 3 becomes 6x + 6y = 18

the equation 6x + 4.5y = 15 stays the same

Subtract to eliminate x.

    6x + 6y = 18

-    6x +4.5y = 15

-------------------------

    0 + 1.5y = 3

1.5y = 3, divide both sides by 1.5 to get y

1.5y    3

----- = -----

1.5       1.5

y = 2

Therefore, there are 2 pounds of "other" chocolate in the gift bag. Let's use that to find the  pounds of the "expensive" chocolate.

Take one of the original equations and plug in "2" for the variable y.

x + y = 3    OR      6x + 4.5y = 15

Lets use x + y = 3, which becomes   x + 2 = 3. Solve that, and you will get:

x = 1

Therefore, there is 1 pound of "expensive" chocolate in the gift bag.

(after you are done solving, plug in the numbers you found to one of the  equations...ps i checked already so those are correct.

e.g 1 + 2 = 3 )

The final values of the angles are:

C0 = A0 = 2

C1 = B1 = -7

theta1 = 0 degrees

C2 = B2 = -7

theta2 = 0 degrees

Here, we have,

To determine the values of C0, C1, theta1 (in degrees), C2, and theta2 (in degrees), we need to match the given expressions for x(t) with the given values for A0, A1, B1, A2, B2, and w.

Comparing the expressions:

x(t) = C0 + C1sin(wt+theta1) + C2sin(2wt+theta2)

x(t) = A0 + A1cos(wt) + B1sin(wt) + A2cos(2wt) + B2sin(2w*t)

We can match the constant terms:

C0 = A0 = 2

For the terms involving sin(wt):

C1sin(wt+theta1) = B1sin(w*t)

We can equate the coefficients:

C1 = B1 = -7

For the terms involving sin(2wt):

C2sin(2wt+theta2) = B2sin(2wt)

Again, equating the coefficients:

C2 = B2 = -7

Now let's determine the angles theta1 and theta2 in degrees.

For the term C1sin(wt+theta1), we know that C1 = -7. Comparing this with the given expression, we have:

C1sin(wt+theta1) = -7sin(wt)

Since the coefficients match, we can equate the arguments inside the sin functions:

wt + theta1 = wt

This implies that theta1 = 0.

Similarly, for the term C2sin(2wt+theta2), we have C2 = -7. Comparing this with the given expression, we have:

C2sin(2wt+theta2) = -7sin(2w*t)

Again, equating the arguments inside the sin functions:

2wt + theta2 = 2wt

This implies that theta2 = 0.

Therefore, the final values are:

C0 = A0 = 2

C1 = B1 = -7

theta1 = 0 degrees

C2 = B2 = -7

theta2 = 0 degrees
