Answer:

The answer is B

Step-by-step explanation:

This is because when you distribute the -4 to 9^6 and 7^-24 you will get 9^-24 and 7^36. Then, you can move the 7^-24 to the denominator because of the negative exponent rule.

The box represents the interquartile range (IQR) from Q1 to Q3 (8 to 15). The line inside the box represents the median (12).

The whiskers extend from the box to the minimum value (2) and the maximum value (35), excluding the outlier.

The outlier (35) is plotted as a point outside the whiskers.

To create a box-and-whisker plot, we need to arrange the data in ascending order first:

2, 6, 8, 8, 9, 12, 13, 14, 15, 20, 35

(a) The median is the middle value of the data when it is arranged in ascending order.

In this case, we have 11 data points, so the median is the value in the middle, which is the 6th value:

Median = 12

(b) The inner quartile range (IQR) is the range between the first quartile (Q1) and the third quartile (Q3).

To find these quartiles, we need to divide the data into four equal parts.

Q1 is the median of the lower half of the data:

Lower half: 2, 6, 8, 8, 9

Median of the lower half = 8

Q3 is the median of the upper half of the data:

Upper half: 13, 14, 15, 20, 35

Median of the upper half = 15

IQR = Q3 - Q1 = 15 - 8 = 7

(c) The upper and lower fences are used to identify potential outliers. The fences are calculated using the following formulas:

Lower fence = Q1 - 1.5 × IQR

Upper fence = Q3 + 1.5 × IQR

Lower fence = 8 - 1.5 × 7 = 8 - 10.5 = -2.5

Upper fence = 15 + 1.5 × 7 = 15 + 10.5 = 25.5

(d) To identify the outlier, we need to look for any data point that falls outside the lower and upper fences. In this case, the value 35 is greater than the upper fence (25.5), so it is considered an outlier.

e) Here is the modified box plot, including the outlier and the values on the plot:

       |        |        |        |        |        |        |

  -2.5 |  2     |  6     |  8     |  12    |  15    |  20    |  25.5

       |        |        |        |        |        |        |

The box represents the interquartile range (IQR) from Q1 to Q3 (8 to 15). The line inside the box represents the median (12). The whiskers extend from the box to the minimum value (2) and the maximum value (35), excluding the outlier. The outlier (35) is plotted as a point outside the whiskers.

The length of the QR is 16 cm when PQR ~MNO

In the given question, it is given that two similar triangles as PQR ~MNO

Then, the corresponding sides will be in equal proportion to each other as follows

PQ / MN = PR / MO = QR / NO

We need to find the length of the side QR

As above relations are given,

\(\frac{PQ}{MN}\) = \(\frac{PR}{MO}\) = \(\frac{QR}{NO}\)

\(\frac{30}{10}\) = \(\frac{5x + 7}{x+5}\) = \(\frac{4x}{\frac{16}{3} }\)

Equating all the fractions, equal to each we'll find

\(\frac{5x + 7}{x+5}\) = \(\frac{30}{10}\)

5x + 7 = 3(x +5)

5x + 7 = 3x + 15

2x = 8

x = 4

The events are mutually exclusive events, so P(A|B) is 0.

In this question,

If two events are mutually exclusive, there is no chance that both events will occur. Being the intersection an operation whose result is made up of the non-repeated and common events of two or more sets, that is, given two events A and B, their intersection is made up of the elementary events that they have in common, then

⇒ A ∩ B = 0

Now the conditional probability, P(A|B) = \(\frac{P(A \cap B )}{P(B)}\)

⇒ \(\frac{0}{0.10}\)

⇒ 0.

Hence we can conclude that the events are mutually exclusive events, so P(A|B) is 0.

The Vickers hardness (HV) test calculates indentation diagonal length (d) when a load is applied to a material.

To determine d when a 0.700 kg load produces a Vickers HV of 650, use the formula: HV = 1.8544 * (F/d^2), where F is the force in Newtons (N) and d is in mm.
First, convert the load to Newtons: F = 0.700 kg * 9.81 m/s^2 ≈ 6.867 N. Next, rearrange the formula for d: d = √(1.8544 * F/HV). Substituting values: d = √(1.8544 * 6.867 N / 650) ≈ 0.044 mm.
So, the indentation diagonal length (d) is approximately 0.044 mm when a 0.700 kg load produces a Vickers HV of 650.

8.55 × \(10^{11}\)

Step-by-step explanation:

The solution to the literal equation is y = x - 2.

To solve inequality in y, we need a number such that the assertion holds if we replace y with that number. Isolating the variable on one side of the inequality and leaving the other terms constant is the first step in resolving the inequality.

From the given information:

4x + 1 = 9 + 4y

To solve for y, we have to switch the sides:

9 + 4y = 4x + 1

Subtract 9 from both sides

9 - 9 + 4y = 4x + 1 - 9

4y = 4x - 8

Divide both sides by 4

None of the Above matches the completely integrated expression \(2x^3 + 2x^2 - 2x + C.\)

We can use the power rule of integration.

To integrate the expression ∫³₁ (6x² + 4x − 2) dx, we can apply the power rule of integration.

The power rule states that the integral of \(x^n\) with respect to x is \((x^(n+1))/(n+1) + C,\) where C is the constant of integration.

Let's integrate each term of the expression separately:

∫ (6x²) dx =\((6/3) * (x^3) = 2x^3\)

∫ (4x) dx = \((4/2) * (x^2) = 2x^2\)

∫ (-2) dx = -2x

Now, we can add up the individual integrals:

∫³₁ (6x² + 4x − 2) dx = \(2x^3 + 2x^2 - 2x + C\)

Therefore, the completely integrated expression is \(2x^3 + 2x^2 - 2x + C,\)where C is the constant of integration.

Answer: x=17

Step-by-step explanation:

1.Identify relationship

Since both the angles are on the inside of both parallel lines and on the same side of the transversal you know that you have a same side interior relationship that makes them supplementary

2. set up equation

because they are supplementary you know that they are equal to 180 which gives the equation: 3x+6+123=180

3. solve the equation

3x+6+123=180

3x+129=180 | combine like terms

3x=51 | subtract 123 from both sides

x=17 | divide by 3 on both sides

The formula for the nth term of the sequence \((-1)^n\) / (2n + 4) creates a sequence that alternates between positive and negative values and gets smaller as n increases.

First, let's break down what the formula for the nth term means. The \((-1)^n\) term is simply a way to alternate between positive and negative values, depending on the value of n. When n is an even number, \((-1)^n\) is equal to 1, and when n is an odd number, \((-1)^n\) is equal to -1.

The denominator, 2n + 4, increases as n increases. This means that as n gets larger, the fraction becomes smaller and smaller since the numerator \((-1)^n\) stays the same. In other words, the sequence alternates between positive and negative terms and becomes smaller as n increases.

To find the first six terms of the sequence, we simply substitute the values 1 through 6 for n in the formula and simplify each term. This gives us:

\(a_1 = (-1)^1 / (2(1) + 4) = -1/6\)

\(a_2 = (-1)^2 / (2(2) + 4) = 1/8\)

\(a_3 = (-1)^3 / (2(3) + 4) = -1/10\)

\(a_4 = (-1)^4 / (2(4) + 4) = 1/12\)

\(a_5 = (-1)^5 / (2(5) + 4) = -1/14\)

\(a_6 = (-1)^6 / (2(6) + 4) = 1/16\)

So the first six terms of the sequence are -1/6, 1/8, -1/10, 1/12, -1/14, and 1/16.

Overall, the formula for the nth term of the sequence \((-1)^n\) / (2n + 4) creates a sequence that alternates between positive and negative values and gets smaller as n increases. By substituting the values 1 through 6 for n, we can find the first six terms of the sequence.
