Answer:

A positive correlation

Step-by-step explanation:

A positive correlation means that two entities are directly proportional to each other. If the value of one increases, the value of the second also increases. Similarly, if the value of one deceases, the other one also decreases.

There is a positive correlation between the two things - heart rate and daily intake of caffeine.

When caffeine intake is high then the heart rate is also high.

Thus a positive correlation can be seen here.

If line P bisects segmentAD at point O and if AO=z+4 and AD =3z-11, find OD
sleet_krkn [62]

Answer:

Line P bisects AD at O.

AD = AO + OD

(3z - 11) = (z + 4) + OD

(3z - 11) - (z + 4) = OD

3z - 11 - z - 4 = OD

2z -15 = OD

Use a proportion to estimate each population. (Please solve both questions, thank you) (I’ll reward you with brainliest :)
hammer [34]

Answer:

<em>Step-by-step explanation:</em>

<em>Step 1. (The capture) Capture a sample  total counted =958, and them back tagged counted=38,total tagged=56 </em>

<em>The idea is to estimate the proportion p = m/N of tagged =102. </em>

<em>Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged. </em>

<em>It is reasonable that, k/n would be a good estimante for p = m/N. </em>

<em>Accordingly, for an estimate N of N, se solve the equation m/N= k/n. </em>

Write an equation of the line that passes through the points (0,4) and (2,10).
andreev551 [17]

Answer:

y = 3x+4

Step-by-step explanation:

Use the coordinates of the points to find the slope of the line passing through them.

slope = Δy/Δx = (10-4)/(2-0) = 6/2 = 3

Point-slope equation for line of slope 3 that passes through (0,4):

y-4 = 3(x-0)

Slope-intercept form of the equation:

y = 3x+4
