Answer:

mean = 24

Step-by-step explanation:

the mean is calculated as

mean = \(\frac{sum}{count}\)

the sum of the data set is

sum = 12 + 13 + 15 + 28 + 28 + 30 + 42 = 168

there is a count of 7 in the data set , then

mean = \(\frac{168}{7}\) = 24

Answer:

Sessions needed= 12

Step-by-step explanation:

Giving the following information:

Total hours= 12 hours

Practice= 3/4= 0.75 of an hour

Already practiced= 3 hours

First, we need to determine how many minutes does she practice each session:

Minutes per session= 0.75*60= 45 minutes

Now, we divide the total practice in minutes required for the minutes per session:

Sessions needed= (9*60) / 45

Sessions needed= 12

The value of y when a = 1 and b = 2 is 22.

The equation of can be solved as follows: We will substitute the value of a and b  in the equation to find the value of y.

Therefore,

y = 3ab + 2b³

Let's find y when a = 1 and b = 2

Hence,

y = 3(1)(2) + 2(2)³

y = 6 + 2(8)

y = 22

Therefore,

y = 22

All of the justifications used to demonstrate the following angles, including the alternate interior theorem justification, are valid.

When a transversal intersects two parallel lines, alternate interior angles are created that are equal to the alternate pairs of those pairs.

The angles formed on the opposing sides of the transversal are known as alternate internal angles.

Angles of the same size that are found on opposing sides of the transversal line are known as alternate angles.

Angles that alternate are equal: By creating a Z form, we can easily identify interior alternate angles: Alternate angles come in two varieties: alternate internal angles and alternate exterior angles.

All the reasons are given to prove the following angles are correct including the reason for the alternate interior theorem.

Therefore, all of the justifications used to demonstrate the following angles, including the alternate interior theorem justification, are valid.

Answer:

StartLayout Enlarged Left-Brace 1st Row y = 280 x 2nd Row y = negative 0.052 (x minus 500) squared + 24,000 EndLayout

Step-by-step explanation:

Given that:

Cost per cleaner = $280

The cost of x vacuum cleaners will be :

Cost per cleaner * number of cleaners

$280 * x

= $280x

The general vertex firm equation :

y-k = a(x-h)^2

Vertex = (500, 24000) ; Vertex = (h, k)

h = 500 ; k =24000 y= 11000, x = 0

y intercept = 11000

Plugging the values :

11000 - 24000 = a(0 - 500)^2

- 13000 = a(-500)^2

-13000 = a * 250000

a = - 13000 / 250000

a = - 0.052

Hence,

y - 24000 = a(0 - 500)^2

y = - 0.052(0 - 500)^2 + 24000

Sorry for my sloppy hand writing.

The y-intercept of the total fee paid by Tyrell on his trip to Chicago when the cab travels 0 miles, the total fee will be $10.00.

The total fee paid by Tyrell is made up of a fixed cost and a variable cost. The fixed fee is the fee that is incurred regardless of the miles travelled. The variable fee is the fee that changes with the distance travelled.

The total fee paid can be modelled as a linear function. A linear function is a single variable that is raised to the power of one.

Total fee = fixed fee + variable fee

Variable fee = (change in total fee ) / (change in total miles)

(17.50 - 13) / (5 - 2)

4.50 / 3 = 1.50

Fixed fee = $13 - (1.50 x 2)

$13 - 3 = $10

The fixed fee, $10 is equivalent to the y-intercept.

Using the binomial distribution, it is found that there is a 0.957 = 95.7% probability that he sells less than 3 cars.

The formula is:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem:

The probability he sells less than 3 cars is:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).

In which:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{16,0}.(0.05)^{0}.(0.95)^{16} = 0.4401\)

\(P(X = 1) = C_{16,1}.(0.05)^{1}.(0.95)^{15} = 0.3706\)

\(P(X = 2) = C_{16,2}.(0.05)^{2}.(0.95)^{14} = 0.1463\)

Then:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.4401 + 0.3706 + 0.1463 = 0.957.

0.957 = 95.7% probability that he sells less than 3 cars.

For the statement "If a polygon lacks right angles, then it is a parallelogram.", the counter example is -

Option A : a right triangle

What is a parallelogram?

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side.

A counterexample for a conditional statement is an example that satisfies the hypothesis (the first part of the statement) but does not satisfy the conclusion (the second part of the statement).

In this case, the statement is "If a polygon lacks right angles, then it is a parallelogram."

A right triangle is a polygon that lacks right angles, but it is not a parallelogram.

Therefore, a right triangle is a counterexample for this statement.

A square, a regular hexagon, and a rectangle all have right angles, so they are not counterexamples for this statement.

Therefore, the triangle is the counterexample.

Using properties of square,

a. Equation for total area = 2x² - 16x + 64

b. Area will be minimum for the value of x = 0

c. Minimum area will be 64cm².

With four equal sides, a square is a quadrilateral. There are numerous square-shaped objects in our immediate environment. The equal sides and 90° internal angles of each square form serve as indicators of its identity.

Total length of wire = 32cm.

Now side of one square is given as x.

Perimeter of big square will be = 4x.

Now perimeter of small square = 32- 4x.

Side of small square = (32-4x)/4

= 4(8-x)/4

= 8-x

Area of big square = x × x

= x².

Area of small square = (8-x) ².

Now Total area, A(x) = x² + (8-x) ²

= x² + 64 + x² - 16x

= 2x² - 16x + 64

The side length that will minimize the area will be, x = 0.

Minimum area of the total figure will be = 64cm²

line g:   P1=(x1,y1) = ( -6,1)    and parallel to  f  ( same slope)

use point-slope, again  

y-y2 = m(x-x1)

y-1=\(\frac{1}{6}\)(x-(-6))

y-1 =\(\frac{1}{6}\)(x+6)

y-1 = \(\frac{1}{6}\)x +1

y = \(\frac{1}{6}\)x + 1 +1
