Answer: 400 ft

Step-by-step explanation:

Since the triangles are Congruent Triangles (similar)

x/40  =  50/5

Cross multiply

5x = 2000

divide both sides by 5

5x/5 = 2000/5

x = 400 ft

The equation in point-slope form is y = 6x - 45.

To write an equation in point-slope form of the line through point J(5,-3) with slope 8

The slope of a curve at a particular point is given by the ratio of rise over run at that particular point. It has many applications in the field of coordinate geometry.

Given: Point (5, -3) and Slope m = 8

Now, we use the point-slope formula,

y - y1 = m (x - x1)

Here, x1 = 5 and y1 = -3.

Hence, substituting the values in the above equation, we get

y + 3 = 8 (x - 5)

⇒ y + 3 = 8x - 40

⇒ 8x - y = 40 - 3

⇒ y = 8x - 37.

Hence, the equation in point-slope form for the line through the given point with the given slope m = 6 and point (8, 3) is y = 6x - 45.

Response Bias

Explanation:

Response bias occurs when participants in a research study have a tendency to reply falsely to research surveys. It is mainly caused by poor survey design, example ambiguous use of likert scale in survey questions. In this case, participants have a pre-recorded response to survey questions which would not accurately represent the population as participant replies are likely to be false.

Step-by-step explanation:

Notice that the diagram consists of two right triangles, as shown in the diagram below.

The hypotenuse of the triangle on the left is equal to 13.55, whereas another of its sides is equal to 13.7. According to the Pythagoras theorem,

In our case,

The last result is impossible since there is no positive number a such that a^2=-4.0875.

Therefore, the triangle on the left cannot exist, the diagram is incorrect.

Answer:

Step-by-step explanation:

kinda confusing but ill do my best :/

if what youre saying is m(x) = -4 like x = -4 then do this

plug in -4 for x and solve

 = 2(-4) - 10

  = -8 - 10

 = -18

or are you saying like the whole equation is equal to -4 and we need to solve for x do this

plug in -4 for 'y'

-4 = 2x - 10

then solve for x

6 = 2x

3 = x

sorry if this is confusing but i hope this helps <3

Therefore, the probability that the sample mean will be larger than 1,221 is 0.2005.

To find the probabilities for the sample mean of SAT scores, we need to use the normal distribution probability formula, which can be written as:

P (a < X < b) = Φ (b) - Φ (a)

where X is a normal random variable with mean μ and standard deviation σ, a and b are any two values, and Φ is the cumulative distribution function of the standard normal distribution.

The sample mean of SAT scores is also a normal random variable, with a mean equal to the population mean (1,200) and a standard deviation equal to the population standard deviation (200) divided by the square root of the sample size (64). Therefore, the standard deviation of the sample mean is 200 / √64 = 25.

To find the probabilities for each part of the question, we need to standardize the sample mean by subtracting the mean and dividing by the standard deviation, and then use a table or a calculator to find the values of Φ. Here are the steps for each part:

(a) the probability that the sample mean will be larger than 1,221

P (X > 1,221) = P (Z > (1,221 - 1,200) / 25)

P (X > 1,221) = P (Z > 0.84)

P (X > 1,221) = 1 - P (Z < 0.84)

P (X > 1,221) = 1 - Φ (0.84)

P (X > 1,221) = 1 - 0.7995

P (X > 1,221) = 0.2005

(b) the probability that the sample mean will be less than 1,231

P (X < 1,231) = P (Z < (1,231 - 1,200) / 25)

P (X < 1,231) = P (Z < 1.24)

P (X < 1,231) = Φ (1.24)

P (X < 1,231) = 0.8925

Therefore, the probability that the sample mean will be less than 1,231 is 0.8925.

(c) the probability that the sample mean will be between 1,200 and 1,215

P (1,200 < X < 1,215) = P ((1,200 - 1,200) / 25 < Z < (1,215 - 1,200) / 25)

P (1,200 < X < 1,215) = P (0 < Z < 0.6)

P (1,200 < X < 1,215) = P (Z < 0.6) - P (Z < 0)

P (1,200 < X < 1,215) = Φ (0.6) - Φ (0)

P (1,200 < X < 1,215) = 0.7257 - 0.5

P (1,200 < X < 1,215) = 0.2257

Therefore, the probability that the sample mean will be between 1,200 and 1,215 is 0.2257.

(d) the probability that the sample mean will be greater than 1,200

P (X > 1,200) = P (Z > (1,200 - 1,200) / 25)

P (X > 1,200) = P (Z > 0)

P (X > 1

Use the graph ln the left side.

The description of the graph of the function \(y = \frac{1}{x + 2} + 1\) is the description (c)

The equation is given as:

y = StartFraction 1 Over x + 2 EndFraction + 1?

Rewrite properly as:

\(y = \frac{1}{x + 2} + 1\)

The above equation is the translated equation from an inverse function

Step-by-step explanation:

Since the 2 triangles are equal, that means that each pair of angles are also congruent. To know which angles are congruent, you check th order of how the triangles are named. Ex. Angle Q is congruent to Angle A, Angle P is congruent to Angle R, and Angle T is congruent to Angle Z.

The length and width of the rectangle with a perimeter of 378ft are 168ft and 21ft respectively.

The formula used in calculating the perimeter of a rectangle is expressed as;

P = 2( l + w )

Where l is length and w is width.

Given the data in the question;

Let 'x' represent the width of the rectangle.

Plug the given values into perimeter formula and solve for x .

P = 2( l + w )

378 = 2( 8x + x )

378 = 2( 9x )

378 = 18x

18x = 378

x = 378/18

x = 21

Now, we find the length and width of the rectangle.

Width of the rectangle w = x = 21ft

Length of the rectangle l = 8x = 8( 21 ) = 168ft

Therefore, the width of the rectangle is 21ft while its length is 168ft.

You want the price with tax of a $35 pair of shoes subject to a 20% tax.

The tax is the cost of the shoes multiplied by the tax rate. The final price is the sum of the cost of the shoes and the tax:

  final price = price + price × tax rate

  final price = price × (1 + tax rate) = $35 × 1.20 = $42

The final price of the shoes is $42.

Answer:

42$

Step-by-step explanation:

tax increase will be

The system of inequalities  from the options that can be used to obtain the number of glass vases x and the number of ceramic vases  y that Ben could have bought  is option B

B. 22·x + 14·y > 172

x + y ≤ 10

An inequality is a comparison between expressions that are non equivalent.

The cost of the glass vases = $22

Cost of the ceramic vases = $14

The total cost of the vases > $172

The number of vases Ben bought is no more than 10, therefore;

The variable x represent the number of glass vases Ben bought, and let y represent the number of ceramic vases Ben bought, the possible system of inequalities are found as follows;

Number of glass vases + Number of ceramic vases is less than or equal to 10, therefore, we get;

The total cost obtained by multiplying the number of  units of each item by the number of the item, can be presented as follows;

22 × The number of glass vases + 14 × The number of ceramic vases is more than 172, therefore, we get;

22·x + 14·y > 172
