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.

1/4 the difference of 4/6 + 3/12

Soloha48 [4]

The answer would be about 8/12 because you must convert 4/6 into 8/12. 8/12 + 3/12=11/12
1/4 would be about 3/12, so 11/12 - 3/12=8/12.

Y-3=2(x-3) y+5=2(x+1)

bonufazy [111]

Answer:

The same lines (answer)

Step-by-step explanation:

The equations can be written in slope-intercept form y = mx + c (where 'm' is slope and 'c' is the y-intecept) as,

y-3 = 2(x-3) .......(1) ; y + 5 = 2(x+1) ...........(2)

y = 2x - 6 + 3 ; y = 2x + 2 - 5

y = 2x -3 ; y = 2x - 3

Comparing with slope intercept form we have,

m1 = 2 ; m2 = 2

c1 = -3 ; c2 = -3

If the slopes are equal the lines are parallel and since y-intercepts are also equal means they are the same lines (overlapping)
