Question 2
2 pts
Alex drives to work each morning, and the trip takes an average of u = 38 minutes. The
distribution of driving times is approximately normal with a standard deviation of a = 5
minutes. For a randomly selected morning, what is the probability that Alex's drive to
work will take between 36 and 40 minutes?

Answer:

11 + c

Explanation:

In the parenthesis, 7 + c cannot be simplified, so there is no need for them. Now we have 7 + c + 4. Only 7 and 4 can be added. 7 + 4 = 11. The answer is 11 + c.

Answer:

c+11

Answer:

x = 12

Step-by-step explanation:

180° = (3x - 6) + (8x + 4) + 50°  because all interior angles of a triangle add up to 180°

180° = 11x +48°

11x = 132°

x = 12

Answer:

second one r                  

Step-by-step explanation:

Answer:

The (x,y) point of the vertex is usually labelled as:

Vertex = (h, k)

h = -b / 2a

k = ah^2 + bh + c

f(x) = -3x^2 + 12x -5

a = -3 b=12 c=-5

h = -12 / -6  therefore h = 2

k = -3*2^2 + 12*2 -5

k = -12 + 24 -5  therefore k = 7

Vertex (2, 7)

Step-by-step explanation:

Answer is:

a= 90-70

=20

Answer:

The missing angle is 20°

Step-by-step explanation:

The square by the vertex indicates that this is a right angle. A right angle measures 90°. So what you can do is subtract the 70° from the 90°, to get 20°.

Hope this helps! Have a great day! :)

Hi there! Your answer is -1/9

Please see an explanation for a better and clear understanding to your problem.

Any questions about my answer and explanation can be asked through comments!:)

Step-by-step explanation:

[tex] \large \boxed{ m = \frac{y_2-y_1}{x_2-x_1} }[/tex]

The formula above is slope formula. We will be using this to find a slope of a line.

From the graph, there are two points which are (4,0) and (-5,1).

You can either let (4,0) = (x1, y1) or (x2, y2) but I will be letting (-5,1) =(x2, y2)

Substitute the coordinate points in.

[tex] \large{m = \frac{1 - 0}{ - 5 - 4} } \\ \large{m = \frac{1}{ - 9} } \\ \large{m = - \frac{1}{9} }[/tex]

Hence, the slope is - 1/9. If you are curious where m-term comes from, it comes from y = mx+b where m = slope and b = y-intercept.

Answer:

  a.  see below for diagram. Angle for the length; length for the angle

  b. 6.84°; not to code

  c. 36.1 ft

Step-by-step explanation:

a. The diagram is shown below. Mr. Gow needs to find the angle it makes in order to determine if it is up to code. Alternatively, Mr. Gow needs to find the required length for a ramp that meets code.

__

b. The angle the ramp makes can be found using the tangent relation.

  Tan = Opposite/Adjacent

  tan(angle) = 3/25

  angle = arctan(3/25) ≈ 6.84°

The ramp will make a 6.84° angle with the ground. It will not meet code.

__

c. We can find the distance from the building where the ramp must start using the same trig relation.

  tan(4.75°) = (3 ft)/(distance)

  distance = (3 ft)/tan(4.75°) ≈ 36.1 ft

The ramp must start 36.1 feet from the building to exactly meet code.

ABOVE answer is absolutely correct

Answer:

Experimental Statistical Study

Step-by-step explanation:

Of the three types of statistical study, the one used by the researcher in this question is the experimental statistical study and the reason is as follows:

From the question, a study was conducted on a total of 4 high schools; these high schools were further divided into 2 pairs.

Each pair were subjected to or experimented with different method of teachings. At the end of the semester, the average were compared.

This implies that both pairs were experimented based on different teaching methods and the result of the methods were measured in order to determine which of the methods is better.

This type of study is experimental

Answer:

Experiment ; No, because the schools could be very different, meaning the randomization won't smooth out other effects.

Answer:Los contratos de opciones se pueden tasar utilizando modelos matemáticos como los modelos de precios Black-Scholes o Binomial. El precio de una opción se compone principalmente de dos partes distintas: su valor intrínseco y su valor temporal. ... El valor temporal se basa en la volatilidad esperada del activo subyacente y el tiempo hasta el vencimiento de la opción.

Answer:

  131.3°, 48.7°

Step-by-step explanation:

Let x represent the larger angle. Then x-82.6 is the smaller one. Their sum is ...

  x +(x -82.6) = 180

  2x = 262.6

  x = 131.3

  x -82.6 = 48.7

The two angle measures are 48.7° and 131.3°.

Answer:

46.2%

Step-by-step explanation:

6/13 x 100% = 46.1538461538% (rounded to the nearest tenth: 46.2%)
