Answer:

x=23

(x+11)=34

(3x-35)=34

Step-by-step explanation:

Beause these angles are vertical angles, they are equal.

x+11=3x-35

subtract x from both sides

11=2x-35

add 35 to both sides

46=2x

divide both sides by 2

x=23

Answer:

x = 23

Step-by-step explanation:

x + 11 = 23 + 11 = 34

3(23) - 35 = 34

How did I get that?

x+11 = 3x - 35

x+ 11 +35 = 3x - 35 +35

x+46 = 3x

x - x + 46 = 3x + -x

46 = 2x

46 / 2 = 2x / 2

x = 23

The optimal strategy would be to fit several models to the data using equation mathematical software or tools, and then assess the goodness of fit using statistical metrics like R-squared or Mean Squared Error.

In a mathematical equation, the equals sign (=), which connects two claims and denotes equality, is utilized. In algebra, an equation is a mathematical statement that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a space. Mathematical expressions can be used to describe the relationship between the two sentences on either side of a letter. The logo and the particular piece of software frequently correspond. like, for instance, 2x - 4 = 2.

The following exponential model could be a good fit for the data in the image:

\(f(x) = 7.5 * e^(0.1x) (0.1x)\)

The data is assumed to develop exponentially with a base of e in this model, with a growth rate of 10% for each unit increase in x.

It is crucial to remember that this is only one potential model and that other exponential models with other parameters could also be able to satisfactorily match the data.

The sample is Biased

Step-by-step explanation:

When a survey is being taken, bias is when results are manipulated to intentionally or unintentionally get certain results. This survey is biased because the restaurant is only surveying loyal customers, who all most likely like the restaurant

A way to make the survey random would be by asking multiple different customers that aren't loyal or regular.

Answer:

We can estimate that 900 people in attendance would prefer mustard on a hot dog.

Step-by-step explanation:

What is proportion?

Proportion is a mathematical concept that refers to the relationship between two quantities, expressed as a ratio or a fraction. It represents the size of one quantity relative to another quantity, typically within a larger population or sample.

To determine the number of people who would prefer mustard on a hot dog, we need to use the proportion of people in the sample who prefer mustard and apply it to the total number of people in attendance.

The proportion of people in the sample who prefer mustard is:

27/150 = 0.18

To estimate the number of people who prefer mustard in the entire population of 5,000 attendees, we can multiply this proportion by the total number of attendees:

0.18 x 5,000 = 900

Therefore, we can estimate that 900 people in attendance would prefer mustard on a hot dog.

Answer:

2000 people prefer mustard on their hot dog.

900 people prefer chili on their hot dog

2100 people prefer ketchup on their hot dog

Claires mother did better because her z score was greater than Claires

Step-by-step explanation:

I j took the quiz

Claire's mother did better because her z-score was greater than that of Claires.

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

As per the given information, the solution would be as

Here is Claire's data:

ц₁ = 510

σ₁ = 110

X₁ = 690

⇒ z-score = (X₁-ц₁ )/σ₁

Substitute the values,

⇒ z-score = (690 - 510)/110

⇒ z-score = 180/110

⇒ z-score = 1.636

Here is Claire's mother's data:

ц = 490

σ₂ = 100

X₂ = 680

⇒ z-score = (X₂-ц )/σ₂

Substitute the values,

⇒ z-score = (680 - 490)/100

⇒ z-score = 190/100

⇒ z-score = 1.9

So Claire's mother's z-score > Claire's z-score

Therefore, Claire's mother did better because her z-score was greater than that of Claires.

Answer:

Step-by-step explanation:

Let the length of the rectangular pen be L

let the width be W

Perimeter of the pen P = 2L+2W

Area  A = LW

Given

P = 700ft

L = 100+x

P = 2(100+x) + 2w

P = 200+2x+2w

700 = 200+2x+2w

500 = 2x+2w

250 = x+ w

w = 250-x..... 1

A = (100+x)w ....2

substitute 1 into 2;

A = (100+x)(250-x)

A = 25000-100x+250x-x²

A = 25000+150x-x²

To maximize the area, dA/dx = 0

dA/dx = 150-2x

150-2x = 0

150 = 2x

x = 150/2

x = 75ft

Since

x+w = 250

75+w = 250

w = 250-75

w = 175ft

The width of the rectangular pen will be 175ft

The length will be 100+x = 100+75 = 175ft

Hence the dimension that will maximize the enclosed area is 175ft by 175ft

Answer:

  $2496

Step-by-step explanation:

You want to know the cost of carpeting a 18 ft by 24 ft room with carpet that costs $52 per square yard.

The dimensions of the room in yards are (18 ft)/(3 ft/yd) = 6 yd, by (24 ft)/(3 ft/yd) = 8 yd.

In square yards, the area is ...

  (6 yd)(8 yd) = 48 yd²

The cost of one square yard of carpet is $52, so the cost of 48 square yards will be 48 times as much.

  (48 yd²)($52/yd²) = $(48·52) = $2496

The total price to carpet the floor is $2496.

__

Additional comment

We're reluctant to call this the total price, as there are usually additional charges for tax, carpet pad, delivery, installation, removal and disposal of old flooring, and possibly additional materials such as tack strips or thresholds. Repairing mold or water damage, or leveling the floor, can also add cost.

Answer:

\(\displaystyle \frac{118}{125}\)

Step-by-step explanation:

Trigonometry

Calculate

\(\sin (3\sin^{-1}(2/5))\)

We use the formula for the sine of triple angle:

\(\sin 3x=3\sin x-4\sin^3 x\)

And recall:

\(\sin \sin^{-1}x=x\)

For this problem, we set:

\(x=\sin^{-1}(2/5)\)

Thus:

\(\sin 3x=3\sin (\sin^{-1}(2/5))-4\sin^3 (\sin^{-1}(2/5))\)

\(\displaystyle \sin 3x=3*\frac{2}{5}-4\left(\frac{2}{5}\right)^3\)

\(\displaystyle \sin 3x=\frac{6}{5}-4*\frac{8}{125}\)

\(\displaystyle \sin 3x=\frac{6}{5}-\frac{32}{125}\)

\(\displaystyle \sin 3x=\frac{6*25}{125}-\frac{32}{125}\)

\(\displaystyle \sin 3x=\frac{150-32}{125}\)

\(\mathbf{\displaystyle \sin 3x=\frac{118}{125}}\)

Answer:

Step-by-step explanation:

The equation is  \(g(x) = -\frac{1}{16} (x - 1)^2 + 2\)  Graphing this equation below, we get a parabola that opens downwards and intersects the x-axis at x = -2 and x = 4, with a vertex at (1, 2).

To demonstrate the connection between the two variables, a line or curve is drawn between the plotted points.

To graph function g, we need to find its equation that satisfies the given properties. We know that the y-intercept of g is less than that of f, so we can choose it to be 1. Also, the parabola of g opens downwards and its vertex is between the two x-intercepts, which are at x = -2 and x = 4. We can use these points to find the equation of the parabola in the standard form: g(x) = a(x - h)² + k. Using the fact that g(0) = 1 and the x-intercepts, we can solve for a, h, and k. The resulting equation is:

\(g(x) = -\frac{1}{16} (x - 1)^2 + 2\)

Graphing this equation, we get a parabola that opens downwards and intersects the x-axis at x = -2 and x = 4, with a vertex at (1, 2).

To determine the solution for the given inequality, you have to solve it for x:

First, pass 2 to the right side of the inequality by applying the opposite operation to both sides of it:

Next, note that the x-term is multiplied by "-2", to reach the value of x you have to cancel the said multiplication. For this, you have to divide both sides of the expression by "-2"

Now, keep in mind, that when you divide or multiply an inequality by a negative number, the direction of the inequality gets inversed. This means that the symbol "greater than, >" will tur into the symbol "less than. <":

The solution for this inequality will be the values of x less than 11, symbolically: x < 11

Answer:

The probability that one marble drawn at random is not blue is 70%

Answer:

Slope "m" = (y2 – y1)/(x2 – x1).

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1) or rise over run

Answer:

y=mx+b.

Step-by-step explanation:

m represents the slope, or how much the line is increasing/decreasing per every one unit right, and b represents the y-intercept, or the point at which the line crosses the y-axis. y and x don't really represent anything, they just fit in the equation. For example, if a line goes up 2 for every one it goes right, and crosses the y-axis at -3, the equation would be y=2x-3.

If a pole has two wires attached to it, one on each side, forming two right triangles as shown, then the height of the pole is 29.6 feet

Consider the triangle on left hand side

The length of the base = 34 feet

The measure of angle = 41 degrees

Opposite side is the height of the pole

Here we have to use the trigonometric functions

sin θ = Opposite side / Hypotenuse

cos θ = Adjacent side / Hypotenuse

tan θ = Opposite side / Adjacent side

Here we have to use the equation of tan θ

Substitute the values in the equation

tan 41 = Opposite side / 34 feet

Opposite side = 34 × tan 41

= 29.6 feet

Therefore, the height of the pole is 29.6 feet

The probability that a worker selected at random makes between $300 and $350 is 0.1359 Or 13.6%.

A probability distribution that is symmetric about the mean is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean.

Given, Weekly wages at a certain factory are normally distributed.

Mean(\(\overline{x}\)) = 400, S.D(\(\sigma\)) = 50.

Now, Since the wages are normally distributed we know,

\(z = \frac{x - \overline{x}}{\sigma}\).

Therefore,

z = (300 - 400)/50.

z = - 2.

And

z = (350 - 400)/2.

z = - 1.

Now, from the z-table,

P(z ≤ - 2) = 0.0228 and P(z ≤ - 1) = 0.1587.

Combining the two we have P( - 2 ≤ z ≤ - 1) =  0.1587 - 0.0228.

P( - 2 ≤ z ≤ - 1) = 0.1359.

As a result, the likelihood that a randomly chosen employee will earn between $300 and $350 is 0.1359, or 13.6%.
