Answer:

y=-3

Step-by-step explanation:

"varying directly" means there is only a factor between x and y, i.e.:

y = k·x

so k = y/x = -1/3

so if x=9, y = -1/3·9 = -3

A survey of 250 homeless persons showed that 14 were veterans. Find a point estimate for the population proportion of homeless p
snow_lady [41]

Answer:

\hat p =\frac{14}{250}= 0.056

And for this case that represent the 5.6% of the homeless persons who are veterans

Step-by-step explanation:

We know that in a survey of 250 homeless persons 14 were veterans. We can find the estimated proportion of homeless persons who are veterans with the following formula:

\hat p =\frac{X}{n}

The last one is an unbiased estimator of the true population proportion p

And replacing the info given we got:

\hat p =\frac{14}{250}= 0.056

And for this case that represent the 5.6% of the homeless persons who are veterans

Easy question so yall get can get brainliest by answering correctly first
storchak [24]

Answer:

Answer:

Distance is 13.6 units.  

Which means it is 13

Step-by-step explanation:

Given a grid shows the positions of subway stop and house. The subway stop is located at (-7, 8) and house is located at (6, 4).

we have to find the distance between house and the subway stop.

Points are (-7, 8) and (6, 4).

Using distance formula,

D= /(x2-x1)^2+(y2-y1)^2} = (6-(-7))^2+(4-8)^2=(13)^2+16}={169+16}={185}=13.60147\sim13.6units.

Hence, distance between house and the subway stop is 13.6 units.
