Answer:

Mr. Smith

Step-by-step explanation:

Mr Smith is using the better method because he is making use of a larger number of trials such that the result of his experiment whereby he plans to flip the coin 1,000 times, will be more accurate than the result of that of Mr Jones  that only plans to flip the coin only 10 times which allows for the large number correct outcome of the flipping of the coin to balance out the few inaccuracies. Whereby when only 10 trials are used, the few number of the inaccurate outcomes will have a larger impact on the correct result of the experiment.

The acceptable conclusions to a hypothesis test are option a, c, d, f.

What is hypothesis test?

Hypothesis Testing is a way of statistical analysis in which a person can  put his assumptions about a population parameter to the test. It usually  used to estimate the relationship between two statistical variables.

By the property of hypothesis test the following can be stated.

⇒The value of the test statistic lies in the non rejection region. Therefore, there is no evidence to suggest that the alternative hypothesis is true.

⇒ The value of the test statistic lies in the rejection region. Therefore, there is evidence to suggest that the null hypothesis is not true.

⇒The value of the test statistic does not lie in the rejection region. Therefore, there is no evidence to suggest that the alternative hypothesis is true.

⇒ The value of the test statistic lies in the rejection region. Therefore, there is evidence to suggest that the alternative hypothesis is true.

Answer:

  20°

Step-by-step explanation:

You want the measure of angle G in triangle GPQ with side lengths GP=74, PQ=31, QG=88 meters.

The law of cosines tells you the relevant relationship is ...

  PQ² = GP² +GQ² -2·GP·GQ·cos(G)

Solving for angle G gives ...

  G = arccos((GP² +GQ² -PQ²)/(2·GP·GQ))

  G = arccos((74² +88² -31²)/(2·74·88)) = arccos(12259/13024)

We have 95% confidence in our interval, instead of 100%.because we need to account for the fact that a) the sample may not be truly random.

Strictly speaking, a 95% confidence interval means that if we were to take 100 different samples and calculate a 95% confidence interval for each sample, then approximately 95 of the 100 confidence intervals will contain the true mean (μ). In practice, however, we take one random sample and generate one confidence interval, which may or may not contain the true mean. The observed interval may overestimate or underestimate μ. Consequently, the 95% CI is the likely range of the true, unknown parameter. A confidence interval does not reflect the variability in the unknown parameter. Rather, it reflects the amount of random error in the sample and provides a range of values ​​that are likely to include the unknown parameter. Another way of thinking about a confidence interval is that it is a range of possible values ​​of a parameter (defined as a point estimate + margin of error) with a specified confidence level (which is similar to a probability).

In shape (i), there are two electron domains around the central atom. This means that the electron-domain geometry is linear. However, there are two bonding pairs and no lone pairs of electrons around the central atom, resulting in the molecular geometry also being linear.

The concept of electron-domain geometry and molecular geometry is essential in understanding the properties of molecules. The electron-domain geometry is determined by the number of electron domains (bonding or lone pairs) around the central atom in a molecule. On the other hand, the molecular geometry is determined by the arrangement of atoms in the molecule, taking into account the presence of lone pairs.

Knowing the electron-domain geometry and molecular geometry of a molecule is crucial in predicting its polarity and reactivity. For instance, polar molecules have an asymmetric distribution of electron density, while nonpolar molecules have a symmetric distribution. This difference in polarity affects the physical and chemical properties of a molecule, such as boiling point, melting point, and solubility.

In summary, in shape (i), both the electron-domain geometry and molecular geometry are linear, which means that the central atom has two bonding pairs and no lone pairs. Understanding the electron-domain and molecular geometry of molecules is essential in predicting their properties and behavior.

Step-by-step explanation:

Kimberly sent approximately 34 cylindrical boxes that contained soap

Let's assume Kimberly sent a total of 100 gift boxes. Since half of the boxes were cylindrical, that means she sent 50 cylindrical boxes.

If a third of the rectangular boxes contained soap, then 1/3 * (100 - 50) = 1/3 * 50 = 50/3 ≈ 16.7 rectangular boxes contained soap. Since we cannot have a fraction of a box, let's round it down to 16 rectangular boxes containing soap.

Now, since each box contains exactly one gift, the remaining cylindrical boxes must contain the pack of spicy roasted almonds. Therefore, out of the 50 cylindrical boxes, 50 - 16 = 34 cylindrical boxes contain soap.

Answer:

\(BD = 30\)

Step-by-step explanation:

Given

\(AB = 17\)

\(AC = 16\)

See attachment

Required

Find BD

If AC = 16, then:

\(AO = 16/2\) i.e. half the diagonal AC

\(AO = 8\)

The diagonals of a rhombus are perpendicular.

This implies that we can apply Pythagoras theorem.

Using Pythagoras theorem on triangle AOB, we have:

\(AB^2 = AO^2 + OB^2\)

\(17^2 = 8^2 + OB^2\)

\(289 = 64 + OB^2\)

Collect like terms

\(OB^2 = 289 - 64\)

\(OB^2 = 225\)

Take positive square roots of both sides

\(OB = 15\)

To solve for BD, we use:

\(OB = \frac{BD}{2}\) --- i.e. half the diagonal BD

\(BD = 2 * OB\)

\(BD = 2 * 15\)

\(BD = 30\)

The probability of dying between ages 37 and 39 is 1 - e˙37:2.

We can use the formula:
10,000c = 10,000 * μ39 * (1 - e˙37:2)

By substituting the given values into the formula, we can find the value of 10,000c.To determine 10,000c, we need to use the given information about the 2-year select-and-ultimate mortality table.

Let's break down the steps:

Recall that the symbol μ[37]+t represents the select-and-ultimate mortality rate for a person aged 37 plus t years. We are given that μ[37]+t = μ37+t - c, where 0 ≤ t ≤ 2.

We also have the value of e˙37:2, which represents the probability of surviving from age 37 to age 39. The given value is e˙37:2 = 1.7.
Additionally, we know the value of e˙37, which represents the probability of surviving from age 37 to age 38. The given value is e˙37 = 57.5.

Now let's calculate 10,000c:

Step 1:

Find the value of μ39 using the given information.
Since we know that μ[37]+t = μ37+t - c,

we can substitute t = 2:
μ[37]+2 = μ37+2 - c

Step 2:

Calculate μ39.
μ[37]+2 = μ37+2 - c
μ39 = μ37+2 - c

Step 3:

Use the relationship between mortality rates and survival probabilities.
We know that the probability of surviving from age 37 to age 39 is given by e˙37:2 = 1.7.
This means that the probability of dying between ages 37 and 39 is 1 - e˙37:2.

Step 4:

Calculate the value of 10,000c.
We can use the formula:
10,000c = 10,000 * μ39 * (1 - e˙37:2)

By substituting the given values into the formula, we can find the value of 10,000c.

The standard matrix for the linear transformation can be obtained by applying the transformation to the standard basis vectors. Additionally, an explicit formula for the transformation can be derived by observing the pattern in how the transformation operates on the basis vectors.

To determine the determinant of the linear transformation, we need to compute the determinant of its standard matrix. The standard matrix is obtained by applying the transformation to the standard basis vectors [1, 0] and [0, 1], and arranging the resulting vectors as columns. Let's denote the resulting vectors as [a, b] and [c, d]. The standard matrix for the transformation is then [[a, c], [b, d]]. The determinant of this matrix, denoted as det(A), provides the determinant of the linear transformation.

To find the explicit formula for the linear transformation, we examine how it operates on the basis vectors [1, 0] and [0, 1]. By applying the transformation, we obtain [a, b] and [c, d] respectively. From this pattern, we can deduce the formula for the transformation as T(x, y) = [ax + by, cx + dy], where a, b, c, and d are the entries of the standard matrix.

In summary, the determinant of the linear transformation is given by det(A), where A is the standard matrix. The standard matrix is obtained by applying the transformation to the standard basis vectors, and the explicit formula for the transformation is T(x, y) = [ax + by, cx + dy].

The amount invested in the fund earning 8.5% is $40,000 whereas $20,000 was invested in the fund earning 10%

What is the return on each fund?

The return on each fund is determined as the amount invested multiplied by the interest rate on the fund

;Let X be the amount invested at 8.5%

Interest=8.5%*X=0.085X

The interest of the fund  invested at 10%=($60,000-X)*10%

The interest of the fund  invested at 10%=$6000-0.10X

Total interest=0.085X+6000-0.10X

Total interest earned during year 1=$5,400

Step-by-step explanation:

-5/4 is smaller than -2/3 since on the negative sides, any number who is larger is smaller.

0.75 is smaller than the square root of 3 since that equals to 1.7.

1.9 is smaller than the absolute value of -4 since that equals to 4.

Answer:

B) -2.5, -5/4, -2/3, 0.75, √3 (square root of 3), 1.9, |-4|

Step-by-step explanation:

The square root of 3 is ≈ 1.7, -5/4=-1.25, -2/3=-0.66..., and you have |-4|(absolute value of four)=4. So if you just transition values that are squared, fractions, etc to numbers that are easier to use, it makes it much easier to list them from least to greatest or greatest to least. You would list the negatives first, then positives. I hope this helps you and good luck with your assignment.
