Finally, we can find the critical value of the test statistic using a z-table or a calculator. For a one-tailed test at a 0.05 level of significance, the critical value is approximately 1.645.

The parent needs:

2112 cups - 23 cups = 2089 cups

As an improper fraction, this is:

=2089/1

To determine whether we can conclude that more than half of internet users have posted photos or videos online, we need to perform a hypothesis test. We can state the null hypothesis as "less than or equal to 50% of internet users have posted photos or videos online" and the alternative hypothesis as "more than 50% of internet users have posted photos or videos online."

Next, we need to choose a level of significance, which represents the maximum probability of rejecting the null hypothesis when it is actually true. Let's choose a level of significance of 0.05.

Using the information given, we can calculate the sample proportion of internet users who have posted photos or videos online as:

P = 855/2112 ≈ 0.405

We can then calculate the test statistic using the formula:

z = (P - p₀) / √(p₀(1-p₀) / n)

where p₀ = 0.5 (the proportion specified in the null hypothesis) and n = 2112. Plugging in the values, we get:

z = (0.405 - 0.5) / √(0.5(1-0.5) / 2112) ≈ -9.00

Since our test statistic (z = -9.00) is much smaller than the critical value, we reject the null hypothesis and conclude that there is sufficient evidence to support the claim that more than half of internet users have posted photos or videos online.

The value of c is 98 and the expected value of X is 0.

To find the value of c, we integrate the joint probability density function over the entire range of x and y, and set the result equal to 1 (since the total probability over the entire range must equal 1):

Integrating f(x,y) over the range -y/14 ≤ x ≤ y/14 and 0 < y < ∞:

∫∫ f(x,y) dx dy = c ∫0^∞ ∫-y/14^y/14 (y^2 - 196x^2) e^(-y) dx dy

Using integration by parts with u = y^2 - 196x^2 and dv = e^(-y) dx, we get:

∫-y/14^y/14 (y^2 - 196x^2) e^(-y) dx = (-1/196) e^(-y) [(y^2 + 196y/14 + 98) - (y^2 - 196y/14 + 98)]

= (-1/98) e^(-y) y

Integrating over the range 0 < y < ∞:

c ∫0^∞ (-1/98) e^(-y) y dy = c/98

Setting this equal to 1:

c/98 = 1

c = 98

Therefore, the joint probability density function is:

f(x,y) = 98(y^2 - 196x^2) e^(-y), -y/14 ≤ x ≤ y/14, 0 < y < ∞

To find the expected value of X, we integrate X times the marginal probability density function over the range of X:

f_X(x) = ∫f(x,y) dy from 0 to ∞:

= 98 ∫0^∞ (y^2 - 196x^2) e^(-y) dy

= 98 [(2/7) - 28x^2]

So the expected value of X is:

E(X) = ∫x f_X(x) dx from -∞ to ∞:

= ∫-∞^∞ x f_X(x) dx

= 98 ∫-∞^∞ x [(2/7) - 28x^2] dx

To find the volume of the solid obtained by rotating the region bounded by the curves y = 0, y = cos(2x), x = π/4, and x = 0 about the axis y = -1, you can use the disk method.

The disk method formula for this problem is V = π∫[R(x)^2 - r(x)^2]dx, where V is the volume, R(x) is the outer radius, r(x) is the inner radius, and the integral is from x = 0 to x = π/4.

Since the axis of rotation is y = -1, the outer radius R(x) is 1 + cos(2x) and the inner radius r(x) is 1.

Now, plug in the values into the formula:

V = π∫[ (1 + cos(2x))^2 - (1)^2 ]dx from x = 0 to x = π/4

Evaluate the integral and calculate the volume:

The value of the differentials dw/ds = (s + 4t)(5 - 4t)(st² + t²) and dw/dt = -32st³ + 14st + 20t - 16t²s.

We have the function W = xyZ, where x = s + 4t, y = 5 - 4t, and z = st². We need to find dw/ds and dw/dt.

To find dw/ds, we use the product rule of differentiation.

dw/ds = d/ds (xyZ) = (d/ds(x))(yZ) + (x)(d/ds(yZ))

Using the chain rule, we get:

d/ds(x) = d/ds(s + 4t) = 1 + 0 = 1

d/ds(yZ) = (dy/ds)(Z) + (y)(d/ds(Z)) = 0 + (5 - 4t)(t²) = 5t² - 4t³

Therefore,

dw/ds = (1)(yZ) + (x)(5t² - 4t³) = (s + 4t)(5 - 4t)(st²) + (s + 4t)(5 - 4t)(t²)

dw/ds = (s + 4t)(5 - 4t)(st² + t²)

To find dw/dt, we use the same product rule of differentiation.

dw/dt = d/dt (xyZ) = (d/dt(x))(yZ) + (x)(d/dt(yZ))

Using the chain rule again, we get:

d/dt(x) = d/dt(s + 4t) = 0 + 4 = 4

d/dt(yZ) = (dy/dt)(Z) + (y)(d/dt(Z)) = (-4)(st²) + (5 - 4t)(2st) = 10st - 8st² - 4t

Therefore,

dw/dt = (4)(yZ) + (s + 4t)(10st - 8st² - 4t) = 4(5 - 4t)(st²) + (s + 4t)(10st - 8st² - 4t)

The pet store is selling the kennel for 55.03% more than what they paid for it at wholesale.

The percent markup is computed by calculating the difference between the selling price and the wholesale cost, dividing that difference by the wholesale cost, and multiplying the result by 100 to express it as a percentage.

In this case, the difference between the selling price and the wholesale cost is:

Markup = Selling price - Wholesale cost

Markup = $98.50 - $63.55

Markup = $34.95

To find the percent markup, we divide this markup by the wholesale cost and multiply by 100:

Percent markup = Markup / Wholesale cost x 100%

Percent markup = $34.95 / $63.55 x 100%

Percent markup ≈ 55.03%

Therefore, the pet store has a markup of approximately 55.03% on the large dog kennel. In other words, the pet store is selling the kennel for 55.03% more than what they paid for it at wholesale.

Matt's coffee shop makes a blend that is a mixture of two types of coffee. Type a coffee costs miguel $4.60 per pound, and type b coffee costs $5.95 per pound. Matt's coffee shop used 50 pounds of Type A coffee in this month's blend.

To answer this question, we can use algebraic equations. Let x be the number of pounds of type A coffee used in the blend. Since there were two times as many pounds of type B coffee used as type A, we know that the number of pounds of type B used is 2x.
The cost of the type A coffee is $4.60 per pound, so the cost of x pounds of type A is 4.6x. Similarly, the cost of the type B coffee is $5.95 per pound, so the cost of 2x pounds of type B is 11.9x.
The total cost of the blend is given as $825, so we can set up the equation:
4.6x + 11.9x = 825
Simplifying this equation, we get:
16.5x = 825
Dividing both sides by 16.5, we get:
x = 50
To help solve this problem, we'll use a system of equations based on the given information. Let's denote the amount of Type A coffee as x pounds and Type B coffee as y pounds.
Since Type B coffee used is two times the amount of Type A coffee, we have the equation:
y = 2x
Now, we know that the total cost of the blend is $825. The cost equation would be:
4.60x + 5.95y = 825
Now we can substitute the first equation into the second equation to solve for x:
4.60x + 5.95(2x) = 825
4.60x + 11.90x = 825
16.50x = 825
Now we divide both sides of the equation by 16.50 to find the value of x:
x = 825 / 16.50
x = 50
So, Matt's coffee shop used 50 pounds of Type A coffee in this month's blend.

A good way to get a small standard error is to use a Large sample. the correct answer is option 1.

The standard error is a measure of the variability of the sampling distribution of a statistic. A smaller standard error indicates that the statistic is more precise and is likely closer to the true population value.

One way to obtain a smaller standard error is to use a larger sample size. This is because a larger sample size tends to produce a more accurate estimate of the population parameter, with less variability. Therefore, option 1, "Large sample," is the correct answer.

The other options, such as a large population, repeated sampling, small sample, or small population, are not necessarily related to obtaining a small standard error.

As W is spanned by n linearly independent vectors in ℝ^n, it means that the dimension of W is also n. This implies that W has the same dimension as ℝ^n, and therefore, W is equal to ℝ^n.

If w is a subspace of rnspanned by n non zero orthogonal vectors, then w is at most n-dimensional because there are only n vectors that can be used to span w. Any vector outside of the span of these n vectors will not be in w. Therefore, the dimension of w is less than or equal to n. Since w is a subspace of rn, which is n-dimensional, w must be a subset of Rn with a dimension less than or equal to n. Therefore, w d Rn. Suppose W is a subspace of ℝ^n spanned by n nonzero orthogonal vectors. This means that W is a vector space that is a subset of ℝ^n, and it can be generated by taking linear combinations of the n nonzero orthogonal vectors.

If two lines have non-zero slopes and the same y-intercept, and their sum of slopes is 0, then the sum of the x-coordinates of their x-intercepts is -2 times the y-intercept divided by one of the slopes.

Let's consider two lines L1 and L2 with equations:

L1: y = m1x + b
L2: y = m2x + b

Here, m1 and m2 are the non-zero slopes, and b is the same y-intercept for both lines. We know that the sum of their slopes is 0, which means:

m1 + m2 = 0
m2 = -m1

Now, let's find the x-intercepts of both lines. To find the x-intercept, we need to set y = 0 in the equations:

For L1:
0 = m1x1 + b
x1 = -b / m1

For L2:
0 = m2x2 + b
x2 = -b / m2

As m2 = -m1, we can rewrite the x2 equation as:
x2 = -b / (-m1)

Now, let's find the sum of the x-coordinates of their x-intercepts (x1 + x2):

x1 + x2 = (-b / m1) + (-b / (-m1))
x1 + x2 = (-b / m1) + (b / m1)

The rational number, which expresses a loss of $ 25. 30 is -253/10 = -25.30. So, option(b) is right one. Similarly, The rational number, which expresses a gain of $ 31.10 = 311/10 = 31.10. So, option(a) is right one.

A rational number is a number that can be represented as the quotient or fraction [tex] \frac{p}{q}[/tex] of two numbers, a numerator p and a non-zero denominator q. Loss always implies something lose or decrease and profit represents something gain or increase. So, loss denotes by negative sign and profit by positive sign. We have to determine rational numbers that expresses a loss of $25.30 and a profit of $31.10. First we consider the loss, to express in rational number form, Loss

= -253 ÷ 10

= -25.3

In case of Profit, express in form of rational numbers as profit, 31.10 = 3110 ÷100 = 311 ÷ 10

= 311/10 = 31.1

Hence, the rational number that expresses a loss of $ 25. 30 is -25.3, and the rational number that represents a profit of $ 31.10 is 31.1.

Answer:

x = √(2^2 + 4^2) = √20 = 2√5

y = √(4^2 + 8^2) = √80 = 4√5

√(2√5)^2 + (4√5)^2) = √(20 + 80) = √100 = 10

The side lengths of the largest triangle are 2√5, 4√5, and 10.

If the supervisor increases the sample size to 600 residents, the estimated percentage of residents would become more accurate. A larger sample size provides a better representation of the population, thus reducing the potential for sampling error. In other words, a larger sample size means that the percentage of residents obtained from the sample would be more representative of the percentage of residents in the population.

For example, if the initial sample size was 100 residents, and the estimated percentage of a certain characteristic was 50%, there is a higher likelihood that this percentage may not accurately represent the true percentage of the population. However, if the sample size is increased to 600 residents, the estimated percentage would likely be closer to the true percentage of the population.

Overall, increasing the sample size allows for more precise estimates of population characteristics and reduces the potential for errors in generalizing sample results to the entire population.

Answer: he travel 80 minutes in the first 4 minutes the bike was stationary for 2 minutes

From the graph we get,

(a) Mr. Bond travelled 80 meters in the first 4 minutes.

(b) For 2 minutes (From 4th minute to 6th minute) the bike was stationary.

(c) Mr. Bond was travelling at greatest speed from 6th minute to 8th minute.

(d) The greatest speed of the car was 50 meters/min.

In given graph, X axis refers to time in minutes and Y axis refers to the distance along road in meters.

Here (4, 80) is a point on the graph.

So, in 4 minutes Mr. Bond rode 80 meters on road.

From 4 to 6 minutes the distance travelled by bike remain same that 80 meters.

Hence, for (6 - 4) = 2 minutes the bike was stationary.

The speed from 0 minute to 4 minutes was = (80 - 0)/(4 -0) = 80/4 = 20 meters/min.

From 4 minutes to 6 minutes the speed remained same.

From 6 minute to 8 minute the speed was = (180 - 80)/(8 - 6) = 100/2 = 50 meters/min.

From 8 minute to 10 minute the speed was = (220 - 180)/(10 - 8) = 40/2 = 20 meters/min.

Hence the Mr. Bond was travelling at greatest speed at 6 to 8 minutes.

So, the greatest speed of the car = 50 meters/min.

Answer:

There is no mode for the following data.

Step-by-step explanation:

This is because the mode is the  value which occurs most frequently in a data set. yet there is not a piece of data that appears the most frequently.  

The mode of this data set is the Independents.

The mode is a statistical term that refers to the value that appears most frequently in a data set. In this case, you have provided data on the number of Republicans, Democrats, and Independents. There are 47 Republicans, 49 Democrats, and 52 Independents.

To determine the mode, we simply look for the highest count among the three groups. In this case, we can see that the group with the highest count is the Independents with a count of 52.

Therefore, the mode of this data set is the Independents. This tells us that Independents are the most frequent group in this particular data set. Remember, the mode is just one way to describe the central tendency of data and should be considered alongside other measures like the mean and median for a more comprehensive understanding of the data distribution.
