Answer:
-3
Step-by-step explanation:
We want (n/p)(1). We can obtain this by finding n(1) and p(1) and then dividing as indicated:
p(1) = 3(1) - 2 = 1
n(1) = 2(1) - 5 = -3
Then (n/p) (1) = -3/1, or just -3
Answer:
in what number is the question ate
The answer is 769.3 cm²
The volume of the cylinder is : V = π r² h
<span>The ratio between the radius of the base and the height of the cylinder is 2:3:
r/h = 2/3
h = 3/2r
V = 1617 cm
</span>π = 3.14
1617 = πr² * 3/2 r
1617 = πr³ * 3/2
1617 * 2/3 = πr³
1078 = πr³
r³ = 1078/π = 1078/3.14 = 343
r = ∛343 = 7 cm
h = 3/2r = 3/2 * 7 = 10.5 cm
The surface area of the cylinder is:
SA = 2πr² + 2πrh
= 2 * 3.14 * 7² + 2 * 3.14 * 7 * 10.5
= 307.72 + 461.58
= 769.3 cm²
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:
they are subtracting 6 from each number
