A test to detect an infection gives a positive result 98% of the time if a person is infected, and it is 97% accurate for people
Mrrafil [7]
The answer is c.) 2%. Since the question is talking about false negatives, meaning the chance that the results are false, then we take a look at the 98% which represents the chance of giving an accurate result for the people who are not infected meaning for those who are positive. Thus, the answer is 2% because this is the remaining percentage if 100-98%.

What is the mean absolute deviation?
Lostsunrise [7]

Answer:

0.8 cm

Step-by-step explanation:

The formula for MAD is attached in the picture.

x_i are the values (data)

x bar is the mean

n is the number of numbers (data)

For figuring out MAD, basically, <em>we subtract the mean from each of the values respectively and take the absolute value and SUM for all of the numbers in the data set. Then we divide by n, the number of numbers.</em>

<em />

Let's do this:

MAD = \frac{|2-3|+|2-3|+|2-3|+|2-3|+|3-3|+|3-3|+|3-3|+|4-3|+|4-3|+|5-3|}{10}\\=\frac{1+1+1+1+0+0+0+1+1+2}{10}\\=\frac{8}{10}=0.8

MAD is 0.8

A sector with a radius 7 cm has an area of 49/3 pi cm2. What is the central angle measure of the sector in degrees?
Alekssandra [29.7K]

Answer:

120°

Step-by-step explanation:

Area of a sector is:

A = πr² (θ/360°)

Plugging in values and solving:

49/3 π = π (7)² (θ/360°)

49/3 π = 49π (θ/360°)

1/3 = θ/360°

θ = 120°
