Answer:

y=4sin(1/4x)

Step-by-step explanation:

1. Either sin or cos graph

y=asin(b(x-c))+d or y=acos(b(x-c))+d

a = amplitude

b = period (2π/b = answer)

c = x-shift (negative)

d = y-shift (positive)

2. Graph each possibility

a = 4

b = 2π/8π = 1/4

c = 0

d = 0

y=4sin(1/4x) or y=4cos(1/4x)

Answer:

Step-by-step explanation:

The square indicates that the total angle is 90 degrees so

d+59=90

d=90-59

d=31 degrees

31 degrees
Explanation: The right angle indicator shows that the angle is 90 degrees in total. If you subtract 90-59 you end up with 31 degrees.

Suppose, 10 students have been selected for the prestigious Sir Abed Scholarship for
their excellent performances in extracurricular activities and academic results. Let’s say,
there are 4 types of award: A (100% +), B (100%), C (97%) and D (95%) . Also, a
student has an equal chance of getting any of these 4 scholarships. What is the
probability that exactly 4 of the 10 students get A and 3 students get C?

Answers

Answer:

0.1459, 0.2503

Step-by-step explanation:

Probability of getting exactly 4 A out of 10,  

P(X==4) = 10C4 (1/4)^4 (3/4)^6

=0.1459

Probability of getting exactly 3 C out of 10,  

P(X==3) = 10C3 (1/4)^3 (3/4)^9

=0.2503

The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 59 and a standard deviation of 3. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 59 and 62

Answers

Answer:

About 34%

Step-by-step explanation:

Given that :

Mean, m = 59 ; Standard deviation, s = 3

Bulb replacement numbering between 59 and 62

For, x = 59

Zscore = (x - m) / s

Z = (59 - 59) / 3 = 0

For x = 62

Z = (62 - 59) / 3 = 1

P(Z < 1) - P(Z < 0)

0.84134 - 0.5

= 0.34134

About 34%

Using the graph below, what would the input (x-value) need to be for an output (y value) of 1?

Answers

Answer:

X = 2

Y = 1

The graph intersects at the exact point of (2,1)

The value of x or the input value is 2 for which the output or the value of y is 1.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a graph of a line shown in the picture

As we can see the line passes through the points (3, 3) and (0, -3)

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

The equation of  the line passes through the points:

( y + 3) = (-3-3)/(0-3)[x - 0]

y + 3 = 2x

y = 2x - 3

Plug y = 1

1 = 2x - 3

2x = 3 + 1

2x = 4

x = 4/2

x = 2

Thus, the value of x or the input value is 2 for which the output or the value of y is 1.
