Use the graphs to solve the simultaneous linear equations

Delicious77 [7]

Answer:

x = 2 and y = 5

Step-by-step explanation:

Given the simultaneous linear equations

y = 2x + 1 and x + y = 7

We are to find the value of x and y;

Substitute 1 into 2

From 2;

x+y = 7

x+2x+1 = 7

3x+1 = 7

3x = 7-1

3x = 6

x = 6/3

x = 2

Recall that y = 2x+1

y = 2(2) + 1

y = 4+1

y = 5

Hence the solution from the graph will be the point where the line cuts the x axis and this will be at x = 2 and y = 5

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
