Mathematics
1 answer:
zaharov [31]2 years ago
4 0

Answer:

28 polio vaccinations and 32 measles vacinnacions.

Step-by-step explanation:

x= polio vaccinations

y= measles vaccinations


here we have an ecuation system:

x+y=60 (vaccinations)

2x+4y=184 (doses)

In order to solve it I will solve the x in the first ecuation:

x=60-y

And replace it on the other ecuation:

2(60-y)+4y=184 -----> 120-2y+4y=184------>2y=64------->y=32

Now I replace this result in x=60-y, so x=28.

horrorfan [7]
This is a function where:
x - time in minutes;
y = f ( x ) - altitude of a plane in feet.
Max altitude = 35,000 feet
0.5 h + 2 h + 15 min = 30 min + 120 min + 15 min = 165 min
Domain:
x ∈ [ 0;  165 ]
Range:
y ∈ [ 0;  35,000 ]

butalik [34]

Answer:

0.95988 (Accuracy of the test )

Step-by-step explanation:

To determine the accuracy of this test we have to list out the given values

Prevalence rate of the disease = 0.3% = 0.003

sensitivity rate of the disease = 92% = 0.92

specificity rate for the test = 96% = 0.96

The accuracy of the test can be found using this equation

Accuracy = sensitivity * prevalence + specificity ( 1 - prevalence )

                = 0.92 * 0.003 + 0.96 ( 1 - 0.003 )

                = 0.00276 + 0.95712

                = 0.95988
