Step-by-step explanation:

The measure of the angle 4 is 42°.

A pair of angles formed on a straight line are said to be a linear pair. The sum of angles of a linear pair is always 180 degrees.

Given that, the measure of angle 3 is (23x)°, and the measure of angle 4 is (7x)°, we need to find the measure of angle 4,

Since, angle 3 and angle 4 are linear pair angles, therefore,

∠3 + ∠4 = 180°

23x + 7x = 180°

30x = 180°

x = 6

Therefore, ∠4 = 7 × 6

∠4 = 42°

Hence, the measure of the angle 4 is 42°.

Interquartile range of the scores is 7.

When values are ranked from lowest to highest, the IQR designates the middle 50% of those values. Find the median (middle value) of the bottom half and upper half of the data before calculating the interquartile range (IQR). Quartile 1 (Q1) and Quartile 3 are these values (Q3). The IQR represents the variation between Q3 and Q1. The strongest indicator of variability in data sets with outliers or skewed distributions is the interquartile range. It's unlikely to be impacted by outliers because it's based on numbers that come from the center half of the distribution.

Given Set

16, 12, 20,35,21,17,19,20,13,12,15

12, 12, 13, 15, 16, 17, 19, 20, 20, 21, 35

25 percentile(Q₁) = 13

50 percentile(Q₂) = 17

75 percentile(Q₃) = 20

Interquartile range = Q₃ - Q₁

Interquartile range = 20-13

Interquartile range = 7

Step-by-step explanation:

The choice that is equivalent to the given product when x>0 is (C) x/2.

The result of multiplying two terms with two different signs will be negative, while the product of two factors with the same signs will be positive.

(xa * xb) = x(m + n) if x is a variable and a and b are positive integers.

To simplify the given product, we can combine the square roots and simplify the coefficients:

\($\begin{aligned} \sqrt{\frac{3x}{2}}\times\sqrt{\frac{x}{6}} &= \sqrt{\frac{3x}{2}\cdot\frac{x}{6}} \ &= \sqrt{\frac{3x^2}{12}} \ &= \sqrt{\frac{x^2}{4}} \ &= \frac{x}{2} \end{aligned}\)

Answer:

Option (A)

Step-by-step explanation:

The given expression is,

\((5^{-2}\times 4^{-4})^{-2}\)

Since \(x^{-1}=\frac{1}{x}\) and \(\frac{1}{x^{-1}}=x\)

\(5^{2}=\frac{1}{5^{-2}}\)

\(4^{2}=\frac{1}{4^{-2}}\)

Therefore, \((5^{-2}\times 4^{-4})^{-2}=\frac{1}{(5^{-2}\times 4^{-4})^{2}}\)

                                         \(=\frac{1}{(5^{-2})^2\times (4^{-4})^2}\)

                                         \(=\frac{1}{5^{-4}\times 4^{-8}}\)

                                         \(=\frac{1}{5^{-4}}\times \frac{1}{4^{-8}}\)

Answer: D. x < -1

Explanation:

The empty circle means that the numbers that are included in the inequality do not include -1. Therefore, it cannot be A or B, which say "greater than or equal to" and "less than or equal to" -1.

The arrow is pointing to the left of -1, towards values that are less than -1.

So, the answer must be D: "x is less than -1".

to find a given term, substitute the corresponding value of n into the ninth term formula. For example, if the ninth term is 3n + 2, the 10th term of the sequence can be found by substituting n = 10 into the ninth term. 3 x 10 + 2 = 32 and so, the tenth term of the sequence is 32.

To find the nth term of an arithmetic sequence, use the following formula:

\(an = a + (n - 1)d\)

an(nth term) = a(first term) + (n(term you are looking for) - 1) * d(common difference)

Answer:

[D] −6 < x < 9

Step-by-step explanation:

So, if a < u <b then a < u and u <b

-7 < x - 1 and x -1 < 8

Solving

-7 < x - 1  = x > -6

x - 1 < 8 = x < 9

Combine the intervals

-6 < x < 9

Now looking at the answer choice :

6 < x < 9

−6 > x > 9

6 > x > −9

−6 < x < 9

Thus, the answer is [D] −6 < x < 9

Step-by-step explanation: Hope this help :D

Here, we are given that a room is painted by A, B and C so here three of them have done the work. So, we'll add all these fractions and assume the total work as 1 after that we will substract all the added ones from 1

Let us assume the room completely painted be 1

Now,

A has done 1/3, B has done 1/4 and C has done 1/5 work of the remaining

So, let us add them

Getting the L.C.M. The L.C.M of 3,4,5 is 60

Hence, 47/60 room has been painted

Remaining to paint

Total is assumed as 1

Work done = 47/60

Fraction of room needs to painted = 1 - 47/60

13/60 of the room needs to be painted, OPTION C IS CORRECT

If the archaeologist found a fossil whose length is 489.44 inches, using the conversion table, the length in feet, to the nearest tenth, is 40.8 feet.

The conversion table refers to the tabulated standard units of measurement, showing temperature, length, area, volume, weight, and metric conversions

For instance, the conversion table shows that 12 inches equal 1 foot.

The length of the fossil = 489.44 inches

12 inches = 1 foot

489.44 inches = 40.8 feet (489.44 ÷ 12)

Thus, using the conversion table, which relies on multiplication or division operations using the conversion factors, the length in feet of the fossil is 40.8 feet.

M = 270,000 * (0.5833% * (1 + 0.5833%)^240) / ((1 + 0.5833%)^240 - 1).  Calculating this equation will give us the monthly mortgage payment for Abigail and Curtis Siebert.

Abigail and Curtis Siebert have a $270,000 mortgage at an interest rate of 7% for a term of 20 years.

To calculate the monthly mortgage payment, we can use the formula for an amortizing mortgage:

M = P * (r * (1 + r)^n) / ((1 + r)^n - 1),

where M is the monthly mortgage payment, P is the principal amount (loan amount), r is the monthly interest rate, and n is the total number of monthly payments.

First, we need to convert the annual interest rate to a monthly interest rate. Since there are 12 months in a year, the monthly interest rate is 7% divided by 12, which is approximately 0.5833%.

The total number of monthly payments is the term of the mortgage multiplied by 12. In this case, it's 20 years * 12 months, which equals 240 months.

Now, we can substitute the values into the formula:

M = 270,000 * (0.5833% * (1 + 0.5833%)^240) / ((1 + 0.5833%)^240 - 1).

Calculating this equation will give us the monthly mortgage payment for Abigail and Curtis Siebert.

i belive your asnwer would be -257/24 but what are u trying to find?  

Answer: I think 131

Step-by-step explanation:

Solution :

To claim to be tested is whether "the mean salary is higher than 48,734".

i.e. μ > 48,734

Therefore the null and the alternative hypothesis are

\($H_0 : \mu = 48,734$\)

and \($H_1 : \mu > 48,734$\)

Here, n = 50

\($\bar x = 49,830$\)

s = 3600

We take , α = 0.05

The test statistics t is given by

\($t=\frac{\bar x - \mu}{\frac{s}{\sqrt n}}$\)

\($t=\frac{49,830 - 48,734}{\frac{3600}{\sqrt 50}}$\)

t = 2.15

Now the ">" sign in the \($H_1$\) sign indicates that the right tailed test

Now degree of freedom, df = n - 1

                                              = 50 - 1

                                              = 49

Therefore, the p value = 0.02

The observed p value is less than α = 0.05, therefore we reject \($H_0$\). Hence the mean salary that the accounting graduates are offered from the university is more than the average salary of 48,734 dollar.

Answer:

The scale factor is 2.2

Step-by-step explanation:

To find the scale factor, you look at the length of any two sides that correspond to each other. For example, in the diagram we can see that the side with the length of 4 on the smaller pentagon corresponds to the side with the length of 8.8 on the larger pentagon.

To find the scale factor, you divide the length of the side of the larger pentagon, by the length of the side of the smaller pentagon.

\(\frac{8.8}{4} = 2.2\)

The scale factor is 2.2
