Answer:

shape AREA= 35cm^2

Step-by-step explanation:

you should know that this shape is a combination of triangle and trapezoid. therefore you have to find the area of each shape and add them.

A=h/2(b1 + b2) for trapezoid

A=2/2((4+4)+4)

A=1*12

A=12cm^2

A=bh/2. for TRIANGLE

A=1/2((4+4)*5.75)

A=1/2(46)

A=23cm^2

shape AREA= triangle AREA + trapezoid AREA

shape AREA=12cm^2 + 23cm^2

shape AREA= 35cm^2

The smallest sample observation can be increased by any value up to 0.1 without affecting the value of the sample median.

To find the maximum amount by which the smallest sample observation can be increased without affecting the sample median, we need to consider the definition of the median.

The median is the middle value in a sorted dataset. If the dataset has an odd number of observations, the median is the middle value. If the dataset has an even number of observations, the median is the average of the two middle values.

Since the current smallest sample observation is 8.5, increasing it by any value up to 0.1 would still keep it smaller than any other value in the dataset. This means the position of the smallest observation would not change in the sorted dataset, and therefore, it would not affect the value of the sample median.

The smallest sample observation can be increased by any value up to 0.1 without affecting the value of the sample median.

The probability to answer 5 questions correctly from 14 true or false questions is 0.1222

The given situation represents a binomial experiment, where there are only two possible outcomes for each trial: success (answering correctly) and failure (answering incorrectly). To find the probability of a particular number of successes, we use the binomial probability formula:

P(x)= nCx × p^x × q^(n-x)

Where, n is the total number of trials, p is the probability of success on each trial, q is the probability of failure on each trial (1-p), and x is the number of successes desired.

n = 14 (total number of questions)

p = 1/2 (probability of answering correctly when guessing randomly), and q = 1/2 (probability of answering incorrectly when guessing randomly).

To find P(5), we substitute these values in the formula

P(5) = 14C5 * (1/2)^5 * (1/2)^9= 2002 * (1/32) * (1/512)= 2002 / 16384≈ 0.1222

Answer:

C

Step-by-step explanation:

There are 3 pairs of corresponding sides with proportional lengths.

The ratios of the lengths of corresponding sides are equal AB/XY = BC/YZ = AC/XZ, then ΔABC and ΔXYZ  proven similar through SSS .

To prove two triangles similar using the SSS (Side-Side-Side) similarity criterion, all three pairs of corresponding sides of the two triangles must be proportional .

The SSS similarity criterion states that if the ratio of the lengths of corresponding sides in two triangles is equal, then the triangles are similar.

Given that we have a list of triangles,  to compare the ratios of their corresponding sides to see if any pairs satisfy the SSS similarity criterion.

The three pairs of corresponding sides in the triangles are denoted as follows:

Side A: Sides that are corresponding in length between the two triangles.

Side B: Sides that are corresponding in length between the two triangles.

Side C: Sides that are corresponding in length between the two triangles.

Since the specific list of triangles is not provided, I cannot give you the exact pairs that  proven similar through SSS similarity. However, I provide with an example:

x=(5±)/4

Step-by-step explanation: The quadratic formula has the following form for a quadratic equation ax²+bx+c:

x=(-b±))/(2a)

We apply the quadratic formula and we obtain:

x=(-(-5)±))/(2(2))

x=(-(-5)±))/(4)

x=(-(-5)±))/(4)

Answer:

Step-by-step explanation:

Refer to the graph.  As you 'leave' the first point towards the second, x increases by 3.  This is the 'run.'  At the same time, y increases by 6.  This is the 'rise.'

Therefore the slope is m = rise/run = 6/3, or m = 2.  The second point, (0, 4), is the y-intercept.

If a categorical independent variable contains 4 categories, then four dummy variables will be needed to uniquely represent these categories. a. 1 b. 2 c. 3 d. 4

How many dummy variables are needed to represent the categorical variable?

We need 1 less dummy variable than outcomes for the categorical variable.

categorical variable has 2 outcomes

So, we need 2-1 = 1 dummy variable.

Note: If our categorical variable had 5 outcomes, we would need 5-1 = 4 dummy variables.

b. Write the multiple regression equation relating the dependent variable to the independent variables.

Note: Depending your your professor, this can be written one of the following ways...

yhat = a + b1 x1 + bx2

yhat = b0 + b1 x1 + b2 x2

yhat = beta0hat + beta1hat x1 + betahat2 x2

where x1 is the ratio variable

and x2 is the dummy variable

c. Interpret the meaning of the coefficients in the regression equation.

b0 = the predicted value of y when x1 and x2 both equal 0.

b1 = the change in y when x1 increases by 1 unit holding x2 constant.

b2 = the predicted difference in y between the two possible outcomes of the categorical variable holding x1 constant

The property that should be used to continue simplifying the above equation is A-^1A = 1. So, correct option is C.

We can start with the equation AB = AC and multiply both sides by A^-1 on the left:

A^-1(AB) = A^-1(AC)

Using the associative property of matrix multiplication, we can simplify the left-hand side:

(A^-1A)B = (A^-1A)C

Using the fact that A^-1A = I (the identity matrix), we get:

IB = IC

Simplifying further using the fact that I times any matrix is that matrix itself, we obtain:

B = C

Therefore, the equivalent equation to AB = AC using A^-1 that simplifies to B = C is A^-1(AB) = A^-1(AC), and the property used to continue simplifying the equation is A^-1A = I.

The correct option is (C) A^-1A = 1, which is equivalent to A^-1A = I, since the identity matrix is denoted as 1 in some contexts.

The arithmetic mean would be the best numerical descriptive measure for comparing average store sales by region and identifying the region with the lowest store sales.

This is because the arithmetic mean is the most commonly used measure of central tendency and is calculated by summing up all the values in a dataset and dividing the result by the number of observations. It provides a good representation of the average sales in each region and is sensitive to extreme values, which can be useful in identifying outliers or regions with significantly lower sales.

The subsetted mean and weighted mean are less commonly used and would not be as suitable for this purpose. The geometric mean is useful for calculating average rates of change or growth over time, but not as suitable for comparing average store sales by region.

We have reached an equation that is not true: 290 = 360. This means that our assumptions were incorrect and there is no solution to this system of equations that satisfies all the constraints

How to measure an angle?

a) To find the measure of angles B, C, and D, we can start by drawing a diagram of the bridge and labeling the angles:

      A

     / \

    /   \

   /     \

  /       \

 /         \

/           \

B             C

\           /

 \         /

  \       /

   \     /

    \   /

     \ /

      D

Since the bridge is perpendicular to the two towers, we know that angles B and C are both 90 degrees. Therefore, we can use the fact that the angles in a triangle add up to 180

degrees to find the measure of angle D:

angle D = 180 - angle A - angle B - angle C

       = 180 - 35 - 90 - 90

       = 180 - 215

       = -35

This is an invalid result, since angles cannot be negative. We made a mistake in assuming that angles B and C are both 90 degrees. In fact, they are not necessarily equal to each other, since the bridge may not be perfectly symmetrical. Let's call the measure of angle B x and the measure of angle C y. Then we can use the fact that the angles in a triangle add up to 180 degrees

to get an equation

:

angle A + angle B + angle C + angle D = 180

35 + x + y + angle D = 180

We also know that the sum of the angles around each tower is 360 degrees. Let's call the measure of angle E on one side of the bridge, and the measure of angle F on the other side. Then we can set up two more equations:

angle B + angle D + angle E = 360

x + angle D + angle F = 360

We have three equations and three unknowns (x, y, and angle D), so we can solve for them using

algebra

. First, we can rearrange the first equation to solve for angle D:

angle D = 180 - 35 - x - y

Then we can substitute this expression for angle D into the other two equations:

x + (180 - 35 - x - y) + angle F = 360

(180 - 35 - x - y) + angle E + 90 = 360

Simplifying these equations, we get:

145 - y + angle F = 360 - angle E

145 - x - y + angle E = 270

Now we have two equations and two unknowns (x and y), which we can

solve using

algebra. Let's rearrange the first equation to solve for angle F:

angle F = 360 - 145 + y - x

Substituting this expression for angle F into the second equation, we get:

145 - x - y + (180 - 35 - x - y) + 360 - 145 + y - x = 270

140 - 2x = 0

x = 70

Now we can substitute this value for x into the other equations to get:

angle D = 180 - 35 - x - y

      = 180 - 35 - 70 - y

      = 75 - y

angle F = 360 - 145 + y - x

      = 215 + y - 70

      = 145 + y

145 - y + angle F = 360 - angle E

145 - y + (145 + y) = 360 - angle E

290 = 360

It will take Thomas 40 months to empty the account if he continues to take out $400 each month of $16,000.

To find out how many months it will take for Thomas to empty the account, we need to set M to 0 and solve for t. This will give us the number of months it will take for Thomas to spend all of the $16,000 he won on the game show. The equation we need to solve is:
0 = 16000 - 400t

First, we'll isolate the variable t on one side of the equation by adding 400t to both sides:
400t = 1600

Next, we'll divide both sides of the equation by 400 to get the value of t:
t = 16000/400

Simplifying the right side of the equation gives us:
t = 40
