Answer:
B. 1296 m^3
Step-by-step explanation:
To find the volume of a square pyramid, multiply the base by itself twice, then divide the height by 3. After getting both answers, multiply the answers.
In this case, the base is 18.
The height is 12.
First, we must multiply the base by itself twice.
18⋅18 = 324.
Next, divide the height by 3.
12/3 = 4.
Now that we have both answers, we multiply them.
324 ⋅ 4 = 1,296.
Therefore, 1,296 cm^3 is the volume of the square pyramid.

Answer:
<em>P(B) = 0.46</em>
Step-by-step explanation:
<u>Probability</u>
The complementary event of a given event A is defined as "not A" or the event that A does not occur.
For example, if A is defined as 'getting a job', then the complement of A is 'not getting a job'.
Event A and its complementary event (call it B) must satisfy:
P(A) + P(B) = 1
If we know P(A)=0.54, then
P(B) = 1 - P(A)
P(B) = 1 - 0.54
P(B) = 0.46
Answer:
0.85 ( lowest value proportion to vaccinate )
Step-by-step explanation:
Using the herd immunity relationship
Vc = E - ( E / Ro )
Vc = critical vaccination level
E = vaccine effective against the transmission = 1
Ro = Basic reproduction number
lets assume the effectiveness of the transmission = 100% = 1
lets assume the
Vc = 1 - ( 1 / 3 ) = 67%
but the lowest value proportion to vaccinate = 85%
