Answer:

X = 11

Step-by-step explanation:

4x - 26 = 18

Add 26 on both sides to get 4x alone.

4x - 26 + 26 = 18 + 26

4x = 44

44 divided by 4 is 11.

Therefore X is 11.

Answer: x=11

Step-by-step explanation:

Add 26 to both sides

4x-26+26=18+26

4x=44

Divide by 4 and get 11

x=11

Answer:

The general limit exists at x = 9 and is equal to 300.

Step-by-step explanation:

We want to find the general limit of the function:

[tex]\displaystyle \lim_{x \to 9}(x^2+2^7+(9.1\times 10))[/tex]

By definition, a general limit exists at a point if the two one-sided limits exist and are equivalent to each other.

So, let's find each one-sided limit: the left-hand side and the right-hand side.

The left-hand limit is given by:

Since the given function is a polynomial, we can use direct substitution. This yields:

[tex]=(9)^2+2^7+(9.1\times 10)[/tex]

Evaluate:

[tex]300[/tex]

Therefore:

[tex]\displaystyle \lim_{x \to 9^-}(x^2+2^7+(9.1 \times 10))=300[/tex]

The right-hand limit is given by:

[tex]\displaystyle \lim_{x \to 9^+}(x^2+2^7+(9.1\times 10))[/tex]

Again, since the function is a polynomial, we can use direct substitution. This yields:

[tex]=(9)^2+2^7+(9.1\times 10)[/tex]

Evaluate:

[tex]=300[/tex]

Therefore:

[tex]\displaystyle \lim_{x \to 9^+}(x^2+2^7+(9.1\times 10))=300[/tex]

Thus, we can see that:

[tex]\displaystyle \lim_{x \to 9^-}(x^2+2^7+(9.1\times 10))=\displaystyle \lim_{x \to 9^+}(x^2+2^7+(9.1\times 10))=300[/tex]

Since the two-sided limits exist and are equivalent, the general limit of the function does exist at x = 9 and is equal to 300.

Step-by-step explanation:

Hey there!

Please look your required answer in picture.

Note: In left hand limit always take a smaller near number of the approaching number. For example as in the solution I took the 8.99,8.999 as it is smaller than 9 but very near to it.

And in right hand limit always take a smaller and just greater near number than the approaching number. For example, I took 9.01,9.001 which a just greater but very near to 9.

Hope it helps!

Answer:

the probability of passing the exam if a student does not use ADAPT is 0.3584

Step-by-step explanation:

Given the data in the question;

Probability a student will pass = 38% = 0.38

Probability a student have used ADAPT = 5% = 0.05

P(passed  | used ADAPT) = 79% = 0.79

Now lets use table

                          Used ADAPT                        Not use ADAPT                 Total

Passed            [0.05×0.79] = 0.0395           [0.38 - 0.0395] = 0.3405     0.38

Not Passed     [0.05-0.0395] = 0.0105        [0.62 - 0.0105] = 0.6095     0.62

Total                             0.05                                      0.95

Now, the probability of passing the exam if a student does not use ADAPT will be;

⇒ P(passed and Not used ADAPT) / P( did not use ADAPT)

⇒ 0.3405 / 0.95

⇒ 0.3584

Therefore, the probability of passing the exam if a student does not use ADAPT is 0.3584

Answer: 16 gallons

Step-by-step explanation:

Since the the indicator goes from 1/8 of a tank to 3/4, we need to know the difference and this will be:

= 3/4 - 1/8

= 6/8 - 1/8

= 5/8

Therefore, 10 gallons represents 5/8 of the total capacity. Therefore, the total capacity will then be:

5/8 of x = 10

5x/8 = 10

5x = 10 × 8

5x = 80

x = 80/5

x = 16

Therefore, the total capacity is 16 gallons

Answer:

0.2514 = 25.14% of women have HDL below 45 mg/dl or less.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean HDL cholesterol levels of 55mg/dl with a standard deviation of 15 mg/dl.

This means that [tex]\mu = 55, \sigma = 15[/tex]

What proportion of women have HDL below 45 mg/dl or less?

This is the p-value of Z when X = 45. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{45 - 55}{15}[/tex]

[tex]Z = -0.67[/tex]

[tex]Z = -0.67[/tex] has a p-value of 0.2514

0.2514 = 25.14% of women have HDL below 45 mg/dl or less.

Answer:

A = 6; B = -15

Step-by-step explanation:

To have an infinite number of solutions, both equations must be the same.

4x - Ay = 15

-4x + 6y = B

The only coefficient we see in both equations is the coefficient of the x term. We have -4x and 4x. Multiply both sides of the second equation by -1.

4x - Ay = 15

4x - 6y = -B

For the equation to be equal, we need each term of one equation to be equal to the corresponding term of the other equation.

4x and 4x are equal.

-Ay must equal -6y

-Ay = -6y

-A = -6

A = 6

15 must equal -B

-B = 15

B = -15

Answer: A = 6; B = -15

Answer:

48.37 degrees

Step-by-step explanation:

c = AB = sqrt((9-7)² + (2-7)²) = sqrt(4+25) = sqrt(29)

b = AC = sqrt((5-7)² + (3-7)²) = sqrt(4+16) = sqrt(20)

a = BC = sqrt((5-9)² + (3-2)²) = sqrt(16+1) = sqrt(17)

A = angle at A

B = angle at B

C = angle at C

cos(A) = (b²+c²-a²)/(2bc) = (20+29-17)/2sqrt(20)sqrt(29) =

= 32/48.16637832... = 0.664363839...

A = acos(0.664363839...) = 48.366461... degrees

angle QRS = 51°

The diagram for the question has been attached to this response.

From the diagram, some circle theorems can be applied.

Circle theorem:

The angle subtended by an arc of a circle at the centre is twice the angle subtended by it at any other point on the remaining part of the circle.

From the diagram, QR is the arc and therefore:

∠QSR = 2 x ∠ QTR

Since ∠QTR = 39°

=> ∠QSR = 2 x 39°

=> ∠QSR = 78°

Other theorem:

(i)The base angles of an isosceles triangle are equal.

Triangle QSR is an isosceles triangle, therefore, angles SQR and QRS are equal. i.e

∠SQR = ∠QRS

(ii) The sum of angles of a triangle is 180°. i.e

∠SQR + ∠QRS + ∠QSR = 180°

Since ∠SQR = ∠QRS and ∠QSR = 78°

=> ∠QRS + ∠QRS + 78° = 180°

=> 2(∠QRS) = 180° - 78°

=> 2(∠QRS) = 102°

Divide both sides by 2

=> ∠QRS = 51°

Therefore, angle QRS = 51°

The correct answer is option B which is 8.19 x 10⁵.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division

The given expression will be written as :-

E = ( 5.4 x 10⁵ ) +( 2.9 x 10⁵ ) - ( 1.1 x 10⁴ )

E =  ( 5.4 x 10⁵ ) +( 2.9 x 10⁵ ) - ( 0.11 x 10⁵ )

E = ( 5.4 + 2. 89 -0.11 ) x 10⁵

E = 8.19 x 10⁵

Therefore the correct answer is option B which is 8.19 x 10⁵.

Answer:

-25 feet

Step-by-step explanation:

First she descends 5 feet below sea level

She then descends the SAME DISTANCE ( so 5 feet ) 4 MORE TIMES

So feet descended = 4 * 5 + 5

4 * 5 = 20

20 + 5 = 25

Her final elevation will be -25 feet

( it's important that we add a negative sign because she is descending meaning going down )

Let's say your data is all in column A. Furthermore, we'll say we have 21 items in this column. Make sure this data column is sorted from smallest to largest. If this isn't done, then weird things will happen when it comes to connecting the dots later on.

Column B will be used later, but for now, let's move to cell C1. In this cell, type =AVERAGE(A1:A21)

The equal sign is important to tell Excel that we have a function here, and not just plain text. As the function implies, we're finding the average (aka mean) of values A1,A2,...,A20,A21. This computes the arithmetic mean.

In cell D1, type in =STDEV(A1:A21) to compute the sample standard deviation

There's nothing special about C1 or D1. We just need something off to the side. Think of it like scratch work.

-------------------------

Now move back to column B. In cell B1, type =NORMDIST(A1,$C$1,$D$1,FALSE)

The $C$1 and $D$1 refer to cells C1 and D1 respectively. The dollar signs lock in those rows and columns so they don't change. We don't want the mean and standard deviation to alter. The "False" at the end tells Excel that we don't want a cumulative normal distribution.

The first parameter A1 is the x value. Much like the curve y = x^2, we plug in various x values to find corresponding y values. We'll plot various (x,y) points to connect them with a curve. The more points, the more accurate the curve. Instead of the x^2 function, we're using the NORMDIST function.

Once cell B1 is filled out, click on the bottom right corner of the cell. You should see a very small square at this corner. Dragging this square down until you reach cell B21 will fill in the remaining 20 cells with the formula mentioned in bold; however, the A1 will change depending on what row you're on. Everything else stays the same hence the use of the dollar signs.

-------------------------

In figure 1 below, I'm showing an example of what I've discussed so far. Figure 1 shows the formulas in each cell. This is before they are evaluated.

Figure 2 shows what the formulas evaluate to. The data in column A can be anything you want. I randomly generated the data values between 2 and 17.

Once column B is figured out, you would insert a chart of (x,y) scatter points. Make sure to connect the dots so that a curve forms. This will complete the normal distribution graph. Again, the data in column A must be sorted or else the dots won't be connected properly.

To be perfectly honest, Excel doesn't really do a good job at drawing curves like this. In my opinion, programs like GeoGebra are better suited for the task. Though spreadsheet programs like Excel are still used in a lot of settings, which is why this is good practice.

Answer:

  4

Step-by-step explanation:

In order to evaluate f(g(-1)), you first need to find g(-1).

The graph of g(x) crosses the line x = -1 at y = 1, so g(-1) = 1.

The second step is evaluating f(1). The graph of f(x) crosses the line x=1 at y=4, so f(1) = 4.
