Answer:

C. 120

Step-by-step explanation:

The 'Fundamental Principle of Counting' says 'If an operation p_{i} (where i = 1, 2 , 3, ... , k) is performed in n_{i} (where i = 1, 2 , 3, ... , k) ways respectively, then the entire sequence can be performed in n_{1}*n_{2}*n_{3}*......*n_{k} ways.

Now, we are given the words M, R, O, U, H and are required to form words out of these five letters.

Hence, the number of different ways to list all the five letters is 5*4*3*2*1 i.e. 120 ways.

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 43 o
xeze [42]

Answer:

a) 95% of the widget weights lie between 29 and 57 ounces.

b) What percentage of the widget weights lie between 12 and 57 ounces? about 97.5%

c) What percentage of the widget weights lie above 30? about 97.5%

Step-by-step explanation:

The empirical rule for a mean of 43 and a standard deviation of 7 is shown below.  

a) 29 represents two standard deviations below the mean, and 57 represents two standard deviations above the mean, so, 95% of the widget weights lie between 29 and 57 ounces.  

b) 22 represents three standard deviations below the mean, and the percentage of the widget weights below 22 is only 0.15%. We can say that the percentage of widget weights below 12 is about 0. Equivalently we can say that the percentage of widget weights between 12 an 43 is about 50% and the percentage of widget weights between 43 and 57 is 47.5%. Therefore, the percentage of the widget weights that lie between 12 and 57 ounces is about 97.5%

c) The percentage of widget weights that lie above 29 is 47.5% + 50% = 97.5%. We can consider that the percentage of the widget weights that lie above 30 is about 97.5%

If you wanted to make the graph of y=5x+3 les steep, which equation could you use?
stepan [7]

B

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = 5x + 3 is in this form with slope m = 5

To decrease the slope we require a smaller, positive value for m

y = x + 3 has m = 1 which is less than 5 and positive

y = x + 3 is less steep than y = 5x + 3

____ [38]

Answer:

  (i) x° = 28°

  (ii) y° = 104°

  (iii) z° = 76°

Step-by-step explanation:

x° is an alternate interior angle where transversal PQ crosses the parallel lines, so it has the same measure as the one marked 28°.

  x° = 28°

__

The base angles of isosceles triangle PQR are both z°, so we must have ...

  z° +z° +28° = 180° . . . . . . . . . sum of angles in a triangle

  z° = (180° -28°)/2 = 152°/2 . . . solve for z

  z° = 76°

__

y° and z° are a linear pair, so ...

  y° = 180° -76°

  y° = 104°
