Answer:

4842

Step-by-step explanation:

538 x 9= 4842 proof  i used my calculator

⇒Sum of interior angles of a triangle is 180°

Meaning

\((2x+13)+(3x-43)+x=180\\2x+3x+x+13-43=180\\6x-30=180\\6x=180+30\\6x=210\\\frac{6x}{6} =\frac{210}{6} \\\\x=35\)

x according to the calculation is 35°

⇒To calculate the size of each angle plug in 35° in the place of x and simplify.

3x-43=3(35)-43

The angle labelled 3x-43 is equal 62°

The angle labelled 2x+13° is equal 2(35°)+13°=83°

And the angle labelled x is equal 35°

Answer:

C

Step-by-step explanation:

so, I assume the rent on floor x increases 4% compared to the rent on floor x-1.

and not by x×4% compared to floor 0.

because otherwise there would be no correct answer option.

if my assumption is correct, then C is correct.

with every floor we add 4% to the rent of the previous floor. that means we multiply the rent of the previous floor by 1.04.

so, for the 7th floor we multiplied by 1.04 seven times.

FYI - if we simply added 4% of the rent of floor 0 to every floor, we would then add 4×7 = 28% to the rent on the 7th floor.

and that would mean a rent of

2000 × 1.28 = $2,560

there you see the difference between simply adding a constant % and adding % of %.

Yes, this set of ordered pairs has been generated by a linear function because the relative difference between y-values and x-values is the same no matter which pairs of (x, y) values you use to calculate it.

We have given that,

The ordered pairs below represent a relation between x and y.

(-3,0), (-2,4), (-1,8), (0,12), (1,16), (2,20)

The graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given are ordered pairs are: (-3,0) (-2,4)(-1,8)(0,12)(1,16)(2,20).

It can be seen that there is only a unit increase in x coordinates and a unit increase in consecutive y- coordinates.

Now, if we set up the equation of line as

Here, m =4 and b = 12

So the relationship is linear and represented by the equation

y=4x+12

Hence, the relative difference between y-values and x-values is the same no matter which pairs of (x, y) values you use to calculate it.

The correct option is (B)

Given information: Length of rectangular wooden board, l = (21.4 ± 0.4) cm

Width of rectangular wooden board, w = (9.8 ± 0.1) cm

(a) The area and uncertainty in area of one side of the rectangular wooden board: Area of the wooden board, A = lw

Putting the given values, we get,

A = (21.4 ± 0.4) cm × (9.8 ± 0.1) cm= (21.4 × 9.8) ± (0.4 × 9.8 + 0.1 × 21.4 + 0.1 × 0.4) cm²= 209.72 ± 1.09 cm²

Therefore, the area of one side of the rectangular wooden board is (209.72 ± 1.09) cm².

(b) The volume and uncertainty in volume of the rectangular wooden board: Volume of the wooden board, V = lwh

Given thickness of wooden board, h = (1.2 ± 0.1) cm

Putting the given values, we get,V = (21.4 ± 0.4) cm × (9.8 ± 0.1) cm × (1.2 ± 0.1) cm= (21.4 × 9.8 × 1.2) ± (0.4 × 9.8 × 1.2 + 0.1 × 21.4 × 1.2 + 0.1 × 0.4 × 1.2) cm³= 249.984 ± 1.414 cm³

Step-by-step explanation:

Domain of the radical function of the form f(x) = √(ax + b) + c is given by the solution of the inequality ax + b ≥ 0 and the range is the all possible values obtained by substituting the domain values in the function.

We know that the general form of a radical function is,

f(x) = √(ax + b) + c

The domain is the possible values of x for which the function f(x) is defined.

And in the other hand the range of the function is all possible values of the functions.

Here for radical function the function is defined in real field if and only if the polynomial under radical component is positive or equal to 0. Because if this is less than 0 then the radical component of the function gives a complex quantity.

ax + b ≥ 0

x ≥ - b/a

So the domain of the function is all possible real numbers which are greater than -b/a.

And range is the values which we can obtain by putting the domain values.

A standard normal distribution is a normal distribution with a mean of zero and a standard deviation of one. Option A is the correct answer.

The standard normal distribution, often known as the z-distribution, is a special sort of ordinary distribution with a mean of zero and a standard deviation of one. Option A is the correct answer.

Any normal distribution can be standardized through transforming its values into z scores. The Z scores indicate how many standard deviations a certain result is from the mean. All normal distributions are unimodal, symmetrically distributed, and have a bell-shaped curve. One such distribution is the common normal distribution. On the other hand, a normal distribution's mean and standard deviation can be any value. In the typical normal distribution, the mean and standard deviation remain constant.

A standard normal distribution is a normal distribution with a mean of zero and a standard deviation of one.

A standard normal distribution, also known as the Z-distribution, is a specific type of normal distribution. It has a mean of zero and a standard deviation of one. The Z-distribution is often used in statistics to standardize data and calculate probabilities.

The standard normal distribution is represented by a bell-shaped curve that is symmetric around the mean of zero. The area under the curve represents the probability of a random variable falling within a certain range.

The Z-score, which measures the number of standard deviations a data point is from the mean, is commonly used in hypothesis testing and confidence interval calculations.

The standard normal distribution is widely used in various fields, including finance, psychology, and quality control.

Where h is the number of hours Melanie can rent the bike, and the solution is h < 5.5.

Let's first determine the cost of renting a bike for h hours:

Cost = 8h + 6

Since Melanie wants to rent a bike for less than $50, we can set up the following inequality:

8h + 6 < 50

Now we can solve for h:

8h < 44

h < 5.5

Since Melanie cannot rent a bike for a fraction of an hour, the maximum number of hours she can rent the bike is 5 hours.

Therefore, the inequality that will help Melanie find the maximum number of hours she can rent the bike is:

8h + 6 < 50

Where h is the number of hours Melanie can rent the bike, and the solution is h < 5.5.

By rounding off, we can determine that Mike thought the difference would be 72 whereas it is actually 72.74.

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number.

For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

The crucial figures are preserved when numbers are rounded off.

Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up.

So, Mike calculated 79 as 79.44 and 7 as 6.7, so he calculated the difference as follows:

79 - 7 = 72

Actual figures that differ are:

79.44 - 6.7 = 72.74

Therefore, by rounding off, we can determine that Mike thought the difference would be 72 whereas it is actually 72.74.
