Answer:

The value of f(1) is larger than the value of f(3)

Step-by-step explanation:

Put the numbers in the equation and do the arithmetic.

f(1) = -2(1²) +3(1) +10 = 11

f(3) = -2(3²) +3(3) +10 = 1

11 is larger than 1, so f(1) is larger than f(3).

A new medical test provides a false positive result for hepatitis 2% of the time that is a perfectly healthy subject being teste

Oxana [17]

Given that X be the number of subjects who test positive for the disease out of the 30 healthy subjects used for the test.

The probability of success, i.e. the probability that a healthy subject tests positive is given as 2% = 0.02

Part A:

The probability that all 30 subjects will appropriately test as not being infected, that is the probability that none of the healthy subjects will test positive is given by:

 $P(X)={ ^nC_xp^x(1-p)^{n-x}} \\ \\ P(0)={ ^{30}C_0(0.02)^0(1-0.02)^{30-0}} \\ \\ =1(1)(0.98)^{30}=0.5455$


Part B:

The mean of a binomial distribution is given by

 $\mu=np \\ \\ =30(0.02) \\ \\ =0.6$

The standard deviation is given by:

 $\sigma=\sqrt{np(1-p)} \\ \\ =\sqrt{30(0.02)(1-0.02)} \\ \\ =\sqrt{30(0.02)(0.98)}=\sqrt{0.588} \\ \\ =0.7668$


Part C:

This test will not be a trusted test in the field of medicine as it has a standard deviation higher than the mean. The testing method will not be consistent in determining the infection of hepatitis.

Why do you subtract the area of the circle from the total

posledela

Answer:

To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before.

Write a real world situation that could be represented by the system of equations shown below.

natali 33 [55]

You could say:

y = 4x + 10

John runs 10 miles a week, after every month he adds 4 miles.

y = 3x + 15

Mary runs 15 miles a week, after every month she adds 3 miles.

'y' would represent the total miles and 'x' would represent the number of months.
