The total they paid is $23 because 1 of them bought 4 cookies for $2 each so we multiply 4 and 2 we will get $8 and the other girl bought 5 cookies for $3 each so we multiply 5 and 3 and that is $15 so we add $15 and $8 and we will end up with $23

How to you graph a linear equation when all they say is y=4 what to do
dybincka [34]
-- Find any point where y=4

-- Find another point where y=4

-- With your ruler, draw a line between the two points.
You have a horizontal line, and every point on it has y=4 no matter what 'x' is.

The equation for every straight line is [ y = mx+b ].

This is the line where (m = 0) and (b = 4).

zhenek [66]

Answer:

test statistic is ≈ -0.36

p-value is  ≈ 0.64

There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.

Step-by-step explanation:

a hypothesis test where H_0: mu = 235 and H_1:mu > 235

test statistic can be calculated as follows:

z=\frac{X-M}{\frac{s}{\sqrt{N} } } where

  • sample mean driving distance (233.8 yards)
  • M is the average expected distance that the average golfer can hit the ball under null hypothesis. (235 yards)
  • s is the standard deviation (46.6 yards)
  • N is the sample size (192)

Then test statistic is z=\frac{233.8-235}{\frac{46.6}{\sqrt{192} } } =-0.3568

p-value is  0.64 >0.05

There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.
