4 0

Answer:

I think it would be 21, because 105 / 5 is 21, and if the denominator is the holder spot, it should be 21

The points in the table lie on a line. Find the slope of the line

8090 [49]

Answer:

1/2

Step-by-step explanation:

Pick two of the x's and y's

The first two columns in the table, the x's are -2 and 0 and the y's are 3 and 4.

The x value changes as a +2 and the y value changes from a +1 from the first two columns. Put the +2 as the denominator and the +1 as the numerator. 1/2

Expand and simplify (2x+5y) (x-3y)

Dmitry [639]

Should be simple:

Let's take this one at a time.

2x(x-3y)

You'd get:
$2x^2-3xy$
for the first one.

2nd one:
5y(x-3y)
you'd get:
$+5xy-3y^2$

Put them both together:
$2x^2-3xy+5xy-3y^2$

Combine like terms.

Your Answer:
$2x^2+2xy-3y^2$

Suppose we wish to construct the perpendicular bisector of line segment EF. We can correctly begin by placing the compass point

julia-pushkina [17]

- to a point which is more than halfway to the point F. Then draw an arc around the point. Next place the compass point at F and, keeping the same distance between the points of the compass, draw another arc so as to intersect the first arc at 2 points above and below the line EF. Finally draw a line passing through these 2 points of intersection. This is the perpendicular bisector of EF.

According to a study conducted by an organization, the proportion of Americans who were afraid to fly in 2006 was 0.10. A rando

Nimfa-mama [501]

Answer: No, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.

Step-by-step explanation:

Since we have given that

n = 1400

x = 154

So, $\hat{p}=\dfrac{154}{1400}=0.11$

and p = 0.10

So, hypothesis would be

$H_0:\hat{p}=p\\\\H_a:\hat{p}>p$

So, the test statistic value would be

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\z=\dfrac{0.11-0.10}{\sqrt{\dfrac{0.1\times 0.9}{1400}}}\\\\z=\dfrac{0.01}{0.008}\\\\z=1.25$

At 5% level of significance,

critical value would be 1.96.

Since 1.96>1.25.

so, we will accept the null hypothesis.

Hence, no, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
