Answer:

The area is multiplied by 9

Step-by-step explanation:

Since the area of a kite is the two diagonals multiplied together and then divided by two (turn the kite into two triangles if you don't believe me), then the change in area would be from x*y/2 to 3x*3y/2, which is the same as 9x*y/2, i.e. nine times the original area.

Answer:

The correct answer:  The area is multiplied by 9.

Answer:

a. Mean

b. μ = μ₀

c. 11.5%

d. Yes

Step-by-step explanation:

The given parameters are;

The mean work week for engineers, μ₀ = 63 hours

The standard deviation, σ = 5 hours

The number of engineers in Kara's sample, n = 10 engineers

The responses given by the 10 engineers are;

70; 45; 55; 60; 65; 55; 55; 60; 50; 55

a. The given information which the newly hired is hoping to find out that it is not is the mean

b. The null hypothesis which is that the company claim is correct, is therefore;

Null hypothesis, H₀; μ = μ₀ = 63 hours

c. Kara's mean, [tex]\overline x[/tex] is found as follows;

[tex]\overline x[/tex] = (70 + 45 + 55 + 60 + 65 + 55 + 55 + 60 + 50 + 55)/10 = 57

[tex]\overline x[/tex] = 57 hours

The Z-score is therefore;

[tex]Z=\dfrac{\overline x-\mu }{\sigma }[/tex]

Z = (57 - 63)/5 = -1.2

From the Z-table, we have;

The p-value for P([tex]\overline x[/tex] ≤ 57) =  P(Z ≤ -1.2) = 0.11507

The probability as a percentage given to one decimal place, that the mean would be as low as Kara's mean, P([tex]\overline x[/tex] ≤ 57) = 11.5%

d. Given that the percent percentage chance (11.5%) that the mean could be as low as hers ([tex]\overline x[/tex] = 57 hours) is higher than 10%, she should accept the claim.

Answer:

8 and 5

Step-by-step explanation:

Let the number of feet added = x

(x + 6) ( x + 3) = 40               Remove the brackets

x^2 + 6x + 3x + 18 = 40        Combine like terms on the left

x^2 + 9x + 18 = 40                Subtract 18 from both sides

               -18    -18

x^2 + 9x = 22                        Subtract 22 from both sides

x^2 + 9x - 22 = 0

This quadratic factors

(x + 11)(x - 2)

x + 11 = 0

x = - 11 which makes not sense.

x - 2 = 0

x = 2

The answer is x = 2

Check

6+2 = 8

3+2 = 5

8 * 5 = 4- just as it should.

Answer:

Option (3)

Step-by-step explanation:

Volume of a rectangle = [tex]\frac{1}{3}(\text{Area of the rectangular base)(\text{Height})}[/tex]

Area of the rectangular base = Length × Width

                                                = 7 × 8

                                                = 56 square in.

Height of the pyramid = 9 in.

Therefore, Volume of the given pyramid = [tex]\frac{1}{3}(56)(9)[/tex]

                                                                    = 168 cubic in.

Option (3) will be the correct option.

Answer:

The annual interest rate is 6%

Step-by-step explanation:

Use the formula for simple interest:  i = prt.

Set i = prt equal to $30:  $30 = prt

Solve this for r:

         $30

r = -------------- = ($30) / ($500)  = 0.06

      $250(2)

The annual interest rate is 6%

Answer:

4/11

Step-by-step explanation:

there are 4 green out of 11 total

Answer:

4/11 is the probability you will get a green marble

Step-by-step explanation:

First you must determine the denominator by adding 4 and 7 to make the total number of marbles

4 + 7 = 11.

Next, you have 4 green marbles so you make it 4/11

Lastly, have a great day!

Step-by-step explanation: equilateral triangle, square, regular hexagon

In a regular tessellation 3,4,6 sides can be tessellating regular

polygon.

A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.

First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.

A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.

A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

Answer:

the cannon ball's maximum height is 21 meters rounded to the nearest whole number

Step-by-step explanation:

The maximum height of the cannonball will be 21.06 meters when the time t = 0.9375 seconds.

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

A cannonball has been catapulted through the air and follows the path created by the function given below.

f(t) = -16t² + 30t + 7

where f(t) is the height of the cannonball in meters at any given time (t) in seconds.

Then the height of the cannonball will be given by the differentiation. Then we have

[tex]\rm \dfrac{d}{dx} f(t) = -16t^2 + 30 t + 7 \\\\\\\dfrac{d}{dx} f(t) = -32t + 30[/tex]

Then again differentiate to check whether the value is maximum or minimum.

[tex]\rm \dfrac{d^2}{dx^2} f(t) = -32t + 30\\\\\\\dfrac{d^2}{dx^2} f(t) = -32\\\\\\\dfrac{d^2}{dx^2} f(t) < 0[/tex]

Then the value of the height will be maximum for f'(t) = 0.

         f'(t) = 0

-32t + 30 = 0

             t = 30/32

             t = 0.9375

Then the maximum height will be

f(t) = -16(0.9375)² + 30(0.9375) + 7

f(t) = -14.0625 + 28.125 + 7

f(t) = 21.0625

f(t) = 21.06 meters
