Complete Question
Stillwater Junior High divides students into teams taught by a group of teachers. The table shows the number of students in each team.
Team{Number of Students}
Acers{78}
Blazers{80}
Outbacks{83}
Quasars{77}
Voyagers{82}
<u>Total-400</u>
Answer:
(A)81/399
Step-by-step explanation:
The probability that the Principal selects a voyager on the first try is:
82/400
Since another student is to be selected, the <u>total population has reduced by 1 </u>and the <u>number of voyagers likewise has been reduced by 1.</u>
Therefore:
Probability that another voyager is selected on the second try =
81/399
<u>The correct option is A.</u>
Answer:
<h3>-4≤y≤7</h3>
Step-by-step explanation:
Given the inequality expressions
4y - 7 ≤ 3y and 3y≤5y+8
For 4y - 7 ≤ 3y
Collect like terms
4y - 3y ≤ 7
y ≤ 7
For 3y≤5y+8
Collect like terms
3y - 5y ≤ 8
-2y ≤ 8
y ≥ 8/-2
y ≥ -4
Combining both solutions
-4≤y≤7
<em>Hence the range of values of y that satisfies both inequalities is -4≤y≤7</em>
Answer:
The rule is ( x - 4, y + 3)
Step-by-step explanation:
To multiply these, we use the FOIL method (first, outside, inside, last). Also, 1√2 is equivalent to √2. It's just like saying 1x is the same x.
Multiplying the first values will give you:
√2 * √6 = √12 = √4*3 = √2*2*3 = 2√3
Multiplying the outside values will give you:
√2 * -√10 = -√20 = -√4*5 = -√2*2*5 = -2√5
Multiplying the inside values will give you:
√6 * √6 = √36 = 6
Multiplying the last values will give you:
√6 * -√10 = -√60 = -√4*15 = -2√15
Now you can combine all of the resulting values:
2√3 - 2√5 - 2√15 + 6
I believe this is the answer you're looking for.
