Answer:

Step-by-step explanation:

Given that a lorida poll asked 1200 Floridians whether they would prefer an increase in taxes or a decrease in government services as a way to balance the budget.

H_0: p =0.50\\H_a: p >0.50\\

(Right tailed test)

STd error assuming H0 to be true =\sqrt{pq/n} =0.0144 for n =1200

Mean difference =0.02

Test statistic =1.386

p value = 0.0823

5) If n =2500, std error would be = 0.01

Test statistic Z = 2

p value = 0.25

Vector V is shown in the graph below.
Lady_Fox [76]

Answer:

v = -8i - 6j

Step-by-step explanation:

The starting point is (9, 9)

The direction of the vector is the direction of the arrowhead.

The i is the horizontal component.

The j is the vertical component.

Therefore, to go from the start to the end of the line, we need to travel negative 8 units (horizontally) and negative 6 units (vertically).

Therefore, v = -8i - 6j

What is the point-slope form of a line that has a slope of 3 and passes through point (1, 4)? y minus 4 = 3 (x minus 1) 1 minus
Tresset [83]

Answer:

y - 4 = 3(x - 1)

Step-by-step explanation:

It looks like you have slope 3  and a point (1, 4)

so  it should be  y - 4 = 3(x - 1)

which is your first choice:  y minus 4 = 3 (x minus 1)
