Answer:
68
Step-by-step explanation:
You multipliy 7x4 and you get 28 now you add the 40+28=68.
Answer:
the probability that a test correctly classifies as positive individuals who have preclinical disease
Step-by-step explanation:
Sensitivity represents the true positive percentage
Lets take an example if there is 90% sensitivity that means there are 90% people who have the target disease considered the test positive
So according to the given options, it is the probability in which if the test is done in a correct manner so this means that the positive individuals have the preclinical disease
Therefore the first option is correct
Hi,
A is an arithmetic sequence
U(n)=U(n-1)+3
Answer:
4/3
Step-by-step explanation:
y = -3/4x - 6
m = -3/4
Slope of the line perpendicular to this line = -1/m
= -1 ÷ (-3/4)

Answer:
x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96
Step-by-step explanation:
The two angles above the horizontal line form a linear pair, so they are supplementary. Their measures add to 180 deg. That let's you find the value of x.
28x - 7 + 24x + 18 = 180
52x + 11 = 180
52x = 169
x = 169/52
x = 3.25
Now use the lower left angle and the upper right angle. They are vertical angles, so they are congruent. That allows you to solve for y.
12y + 30 = 24x + 18
We know that x = 3.25.
12y + 30 = 24(3.25) + 18
12y + 30 = 78 + 18
12y = 66
y = 66/12
y = 5.5
I don't know what the problem is asking for since you don't show.
x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96
