A coin is tossed three times. An outcome is represented by a string of the sort HTT (meaning a head on the first toss, followed
Ivanshal [37]

Answer:

Step-by-step explanation:

In this question, the sample space contains 8 elements and has been given as;

          HHT HHH THH HTH HTT TTT TTH THT

1. For event A:

Outcomes of alternating tail and head = THH HTH HTT THT

                                          = 4 outcomes

Pr(alternating tail and head (with either coming first)) = \frac{4}{8}

                                               = \frac{1}{2}

2. For event B:

Outcomes of no tails on the first two tosses = HHT HHH

                                                   = 2 outcomes

Pr (No tails on the first two tosses) = \frac{2}{8}

                                            = \frac{1}{4}

For event C:

Outcomes of a tail on both the first and the last tosses = THT TTT

                                                       = 2 outcomes

Pr(A tail on both the first and last tosses) = \frac{2}{8}

                                                = \frac{1}{4}

A total of 710 tickets were sold for the school play . They were either adult tickets or student tickets. There were 60 more stu
murzikaleks [220]

Answer: 325

Explanation:

Let the number of adult tickets be <em>x </em>

( since there are an unknown amount of tickets for adults, we already know how many student tickets there are)

Let the number of student tickets be <em>x+</em>60

710=<em>x+x</em>+60

710=2x+60

 -60        -60

650=2x

650/2

= 325

Adult tickets=325

Student tickets=385

The answer to this problem
stepan [7]
Let's assume that you are to graph the inequality. 
1.  Graph -3x + 4y = 12.  Note that the x-intercept is (-4,0) and the y-intercept is (0,3).  Use a dashed line, not a solid line, due to the ">" sign.
2.  Choose a test point (e. g., (0,1) ) and subst. these coordinates into -3x + 4y = 12.  Is the equation then true or false?  If true, shade the area (on one side of -3x + 4y = 12 or the other) in which the test point (0,1) lies.  If false, shade the other side of -3x + 4y = 12.

On a 120-question test, a student got 96 correct answers. What percent of the
madreJ [45]

Answer:

80%

Step-by-step explanation:

Percentages are usually found by taking the value that you want to find and dividing it by the whole amount (100% of the total value available). In this case, getting 100% on the test would mean getting 120/120, because 120 points is 100% of the points available. However, the student only got 96 points out of the whole 120 points, so to find the percentage, you do 96/120 to find what part of 96 comes out of 120. Then to convert to percentage, multiply that value by 100 to get your finale value.
