Answer:

AD = 9

Step-by-step explanation:

Using Pythagoras' identity in right triangle ABD , then

AD² + BD² = AB² , substitute values

AD² + 12² = 15²

AD² + 144 = 225  ( subtract 144 from both sides )

AD² = 81 ( take square root of both sides )

AD = [tex]\sqrt{81}[/tex] = 9

Answer:

y = -4x+11

Step-by-step explanation:

x − 4 y + 1 = 0

x+1 = 4y

4y = x+1

y = 1/4x+1/4

pendiente de una recta perpendicular es el recíproco negativo

negative reciprocal 1/4x is -4x

y = -4x+1/4

Con la nueva pendiente, use la forma de intersección de la pendiente y el punto para calcular la intersección usando (2,3) :

y = mx + b or y = -4x+b

3 = -4(2) + b

3 = -8 + b

11 = b

b = 11

y = -4x+11

Answer: The solutions are x = 3+sqrt(2), and x = 3-sqrt(2). The quadratic equation has two solutions because it has a positive discriminant.

Step-by-step explanation:

Using the quadratic formula, we have: 6+-sqrt(8)/2, which become 3+-sqrt(2).

Given that,

Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games.

Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining.

The attached figure shows the equation that Jorge had :

8.25-0.25x=9.75-0.75x

Subtract 9.75 to both sides

8.25-0.25x-9.75=9.75-0.75x-9.75

-1.5-0.25x=-0.75x

Add 0.25x to the both sides,

-1.5-0.25x+0.25x=-0.75x+0.25x

-1.5=-0.5x

⇒ x = 3

Jorge is incorrect at step 2 where he taken -0.25x to the RHS such that -0.75x+0.25x, he get 0.5x instead of (-0.5x). Hence, From Step 1 to Step 2, Jorge did not add 0.25x correctly to both sides.

The type of sampling that the teacher used is of the type: Option D: Convenience sampling

If the sampling is done from the population randomly, without any other rule, then such sampling is called simple random sampling. Items are selected in a fixed size, all randomly.

Sampling which is done by taking the main population divided in categories(called strata), then such sampling from stratas (sub-parts of the population) is called stratified sampling.

In this type of sampling, starting of the sampling is done randomly, but then rest of the samples are collected by an order. Like for example, first point is selected randomly, then all points are selected that they are equidistant from each other in the population.

The word "convenience" summarizes this sampling. It is done in a way that those values from population are sampled which are in convenience with the researcher. Like if some random picking is to be done from beads spread on the ground, then the researcher picking those beads which are closer to him.

So, the math teacher took the sample from a specific part of the whole twelfth class. That's a strata. But sampling was done "only" from 1 strata, which is useless as field trip's data should be taken from other parts of the population too where students might be interested to go for field trip. Thus, its a wrong method of sampling.

That's more of like convenience sampling instead of stratified, where the teacher preferred convenience instead of proper sampling (as the sampling she did is not showing any proper ideology that she might've followed).

Thus, the type of sampling that the teacher used is of the type: Option D: Convenience sampling

Answer: A = 198.6cm²

Step-by-step explanation: The figure includes two semi circles on both ends. These can be solved as a whole circle with a diameter of 10cm because each semi circle is 5cm.

r = 10/2= 5cm

Area of circle:

A = πr²

A = 3.142*5²

A = 3.142*25

A = 78.55

A = 78.6cm²

The remaining section of the shape is a rectangle with a length of 12cm.

To get this, you subtract 10 from 22 because each semi circle is 5cm which adds up to 10cm.

The rectangle has a width of 10cm.

Area of rectangle:

A = lw

A = 12*10 = 120cm²

The total area of the shape:

A = 120 + 78.6

A = 198.6cm²

Step-by-step explanation: Ascending means increasing, so arrange the weights from the smallest to the biggest.

The weights are all in kilograms (kg) so no conversion is needed. Just arrange the weights by the numbers, 28.76 is the smallest here, and 32.63 is the biggest number, and it is repeated, so in that case the order doesn't matter.

Aman can come before Asif and vice versa since they have the same weights.

The  profit does the company make from producing and selling four soccer nets is $109, the correct option is C.

Profit is a financial benefit that is realized when the amount of revenue gained from a business activity.

Given

|Soccer nets per day | Total Cost | Total Revenue |

| 1 | 7$ | $30 |

| 2 | 9$ | $60 |

| 3 | 10$ | $90 |

| 4 | 11$ | $120 |

| 5 | 13$ | $150 |

The total cost in the four soccer = $11

The total revenue in the four soccer = $120

The profit does the company make from producing and selling four soccer nets is;

[tex]\rm Profit = Total \ revenue -Total \ cost\\\\Profit= 120-11\\\\Profit = 109[/tex]

The y-intercept is the value of y when x = 0. Substitute 0 for x in the equation and solve for y.

[tex]2x - 3y = 6[/tex]

[tex]2(0) - 3y = 6[/tex]

[tex] - 3y = 6[/tex]
