Q2.3. What is the lowest value for proportion to vaccinate that protects the entire population from a smallpox epidemic

Mathematics
1 answer:
Sveta_85 [38]3 years ago
7 0

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%

79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100

100-12 = 98

We have to figure out what 88% is

79.30 ---- 100%
X ------------ 88%

Cross Multiply

79.3× 88 = 100x

6978.4 = 100X

69.784 is without taxes

69.784 = 100% {100% because it is the total price.}

69.784 = 100%
X --------- 6.25%

Cross Multiply

69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615


69.784 + 4.3615
74.15 is the answer

Find angles EFG pleaseee
Bumek [7]

Answer:

50 degrees.

Step-by-step explanation:

Angle FGE = 180-(7x+18) because angles on a straight line add up to 180 degrees.

Angle EFG = 180-38-(180-(7x+18))=6x-10 (Angles in a triangle add up to 180)

180-38-\left(-7x+162\right)=6x-10

180-38+7x-162=6x-10

7x-20=6x-10

Add 20 to both sides:

7x-20+20=6x-10+20

7x=6x+10

Subtract 6x from both sides:

7x-6x=6x+10-6x

x=10

Angle EFG=6x-10=6(10)-10=60-10=50

If you have 2 different slopes what is true about the slopes
Anna007 [38]

Answer:

Step-by-step explanation:

If two lines have different slopes, they cannot be the same line. If they share a y-intercept, that means they cross the y -axis at the same y value.  If they share an x value and corresponding y value, they intersect at that point, in this case their y-intercept.

Hope this helped!!
