Answer:
The correct answer is B) 18%
Step-by-step explanation:
Note that the vaccine is already and is 80% effective. This means that if the entire population was administered with the vaccine, only 8/10 would gain immunity leaving 2/10 or 0.2 exposed.
If the new vaccine, therefore, is supposed to be 90% effective, it is only pragmatic to administer it against those who do not have immunity which is 0.2 of the existing population.
So to get the percentage that will develop immunity, we have:
0.2 x 0.9 = 0.18 or 18%

What is the value of sin(t) if Cos(t)=4/5 and t is in quadrant 1
Answer:
0.6 or 3/5
Step-by-step explanation:
If cos(t) = 4/5, then, taking the arccos of both sides, t ≈ 36.86989765. Taking the sin of that gives you 0.6, or 3/5 in fraction form.
Find the 77th term of the arithmetic sequence
-7, -2, 3, ...
Answer:
373
Step-by-step explanation:
first you find the difference between the first two numbers so we do -7 minus -2=-5 then plug it in -7+5=-2 now plug in 5 for the next two numbers -2+5=3 so now we know the rule is +5 now we do 5*76=380 then we do -7+380=373
What is B^y=x in logarithmic form?
Answer:
The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base. In general, y = logb x is read, “y equals log to the base b of x,” or more simply, “y equals log base b of x.” As with exponential functions, b > 0 and b ≠ 1

The first 6 terms of a sequence are shown below.
96, 48, 24, 12, 6, 3,...
What is the 12th term of the sequence?
Answer:
It would either be (1.5, 1 1/2, or 3/2) - they are all the same value just written differently.
Step-by-step explanation:
going from left to right, you can see the pattern of the sequence is to divide each number by 2.
96/2 is 48; 48/2 is 24; 24/2 is 12; 12/2 is 6; 6/2 is 3
taking that knowledge, you would divide 3 by 2, resulting in 1.5 ; 2/3 ; or 1 1/2

What is a triangle?A triangle is a polygon with three edges and three vertices.
Given is a triangle, PQR and measurements of the angles are given as, m∠P=(4x−14), m∠Q=(5x+6) and m∠R=(x−2)
We know that, the sum of the interior angles of a triangle is 180°
Therefore, ∠ P + ∠ R + ∠ Q = 180°
4x-14 + 5x+6 + x-2 = 180°
10x -10 = 180°
10x = 190°
x = 19°
Now, ∠ R = x-2
∴ ∠ R = 19-2
∠ R = 17°
Hence, the measure of angle R is 17°

<1 and <2 are supplementary angles . If m<1=77,then m<2=?
Answer:
m∠2 = 103°
Step-by-step explanation:
Since ∠1 and ∠2 are supplementary angles, together they equal 180. So, you would just subtract 180-77 and get 103. To check if you are correct just add ∠1 and ∠2 ( 77+103) and you'll get 180.
Answer:
Step-by-step explanation:
The sum of two supplementary angles sum up to 180°
Hence <1+<2 = 180°
Given
<1 = 77
Substitute and get <2
<1+<2 = 180
77+<2 = 180
<2 =180-77
<2 = 103°
Hence the measure of <2 is 103°
