A is 8

B is 4

C is 3

D is 5

Area: 100

Now to find area with these its the same except for the triangles here in this photo I showed the area for each figure BY ITSELF so the thing with the triangles the formula is to do base × height thennn ÷ by 2 So i did 4 × 3 = 12 then divide by 2 and got 6 for both of those triangles as you see in the photo! Then I just did base × height for the rectangles! I did 8 × 4 = 32 and since it had a matching rectangle there was another 32 as displayed in the photo then the middle triangle I simply just did 8 × 3 cause thats the base and height and I got 24 now we just have to add these up! 6 + 6 + 32 + 32 + 24 = 100 so 100 is our area! Hope that makes sense and an easy trick for those triangles to remember to divide by 2 is a triangle is half of a rectangle/square like I displayed in another photo Hope that helps!

Timmy wants to buy a scooter and the price was $50. When he goes to the store the second time, he found that the price was marked down by 16%. What was the new price?

Answers

Answer:

kk

Step-by-step explanation:

Answer:

Step-by-step explanation:

20% of 50 is the same as writing 50 x 0.20, so we just do the math on that. Since it was marked down that much, we subtract the found 20% from the 50. The new price of the scooter is $40.

In ΔTUV, the measure of ∠V=90°, TV = 28, UT = 53, and VU = 45. What ratio represents the cosecant of ∠U?

Answers

Answer:

Cosecant U = 53 / 28

Step-by-step explanation:

Please see attached photo for diagram.

We'll begin by calculating the ratio of sine U. This can be obtained as follow:

Angle U = θ

Opposite = 28

Hypothenus = 53

Sine U =?

Sin θ = Opposite / Hypothenus

Sine θ = 28 / 53

Thus,

Sine U = 28 / 53

Finally, we shall determine the ratio of cosecant U. This can be obtained as follow:

Sine U = 28 / 53

Cosecant U =?

Cosecant U = 1 / Sine U

Cosecant U = 1 ÷ 28 / 53

Cosecant U = 1 × 53 / 28

Cosecant U = 53 / 28

Answers

Answer: The probability that x is at most 2 = 0.89

Step-by-step explanation:

Let x be the number of points that can be scored on 1 question of a statistics exam.

Given table: x       0          1           2           3

                P(x) 0.13   0.21     0.55         0.11

[tex]P(X\leq2)=P(X=0)+P(X=1)+P(X=2)\\\\P(X\leq2)= 0.13+0.21+0.55\\\\P(X\leq2)= 0.89\\\\[/tex]

Hence, the probability that x is at most 2 = 0.89

Answers

x and y

x=2y+9

x-y=22

*x is the larger number*

plug in x to solve for y

y=13

plug in y and solve for X

x=2 (13)+9

x=26+9

Martha Realizes that when she ascended the stairs in the school in threes or fours,one step always remain what is the minimum number of stairs​

Answers

9514 1404 393

Answer:

  13

Step-by-step explanation:

The number is 1 more than the least common multiple of 3 and 4. That multiple is 12, so the number of stairs is 12+1 = 13.

Martha's school staircase has 13 steps, minimum.

_____

Additional comment

The real minimum is 1, not 13. We assume that we're interested in the non-trivial solution. (In a public building, staircases between floors often have 14 steps. 13 steps might attract the attention of those who are superstitious.)

Si uno de los ángulos de un triángulo rectángulo mide 37 grados y el lado opuesto mide 60 cm cuánto debe morir el cateto opuesto ?

Answers

Se ha dado el lado opuesto, la pregunta probablemente requiera que calculemos el Adyacente.

Respuesta:

79,62 cm

Explicación paso a paso:

Dado el lado opuesto del ángulo 37 ° = 60cm

Sea el lado adyacente = x

Usando trigonometría:

Tan θ = opuesto / adyacente

Bronceado 37 = 60 / x

0,7535540 = 60 / x

0,7535540 x = 60

x = 60 / 0,7535540

x = 79,62 centímetros

Assume the random variable x is normally distributed with mean p= 80 and standard deviation o = 4. Find the indicated probability.
P(67 P(67 (Round to four decimal places as needed.)

Answers

This question is incomplete, the complete question is;

Assume the random variable x is normally distributed with mean p = 80 and standard deviation σ = 4.

Find the indicated probability.  P(67 < x < 72)

(Round to four decimal places as needed.)

Answer:

the indicated is 0.0222

Step-by-step explanation:

Given the data in the question;

mean μ = 80

standard deviation σ = 4

p ⇒ P ( x -μ  / σ )

so

P(67 < x < 72) ⇒ P( 67-80 / 4 ) < P( x -μ  / σ )  < P( 72-80 / 4 )

P(67 < x < 72) ⇒ P( -13 / 4 ) < P( x -μ  / σ ) < P( -8 / 4 )

P(67 < x < 72) ⇒ P( -13 / 4  < z < -8 / 4 )

P(67 < x < 72) ⇒ P( -3.25  < z < -2 )

⇒ P( z < -2 ) - P( z < -3.25)

Now from z table;

⇒ 0.02275 - 0.00058

P(67 < x < 72) ⇒ 0.02217 ≈ 0.0222  { four decimal places }

Therefore, the indicated is 0.0222
