Answer:

X = 600

Step-by-step explanation:

x-(0.0765x)=554.1

x-0.0765x=554.1

0.9235x=554.1

x=600

Each of a group of 20 intermediate tennis players is given two rackets, one having nylon strings and the other synthetic gut str

sergeinik [125]

Answer:

Find answers below

Step-by-step explanation:

H0: P <= 0.5

Ha: P > 0.5

, the number who prefer gut strings is <= a number or the test tends towards the left-tailed.

{0,1,2,3,4,5} ;

{15,16,17,18,19,20} is a right-tailed test and not appropriate for H0:

{ 0,1,2,3,17,18,19,20} is two-tailed and not appropriate for H0:

Does the region specify a level .05 test? No

P = proportion who prefer gut strings to nylon

P = X /20

Assume alpha = 0.05

z(alpha) = -1.645

Reject if (x/20 - 0.5) / sqrt[ (0.5)(0.5)/20 ] < -1.645

Reject if (x/20 - 0.5) < < (-1.645) sqrt ( (0.5)(0.5)/20 )

Reject if x/20 < (-1.645) sqrt ( (0.5)(0.5)/20 ) + 0.5

Reject if x/20 < 0.316

Reject if x < (0.316)(20) = 6.32

{0,1,2,3,4,5,6} is the region for the best level 0.05 test

According to (a), reject H0 if x <= 5

P( Type II error) = P( do not reject H0/ when Ha is true)

P( Type II error) = P( x > 5/ P=0.6)

x ---p(x)

What is bigger 400 pints or 100 gallons

Anton [14]

Easy,

100 gallons=800 pints

There are 8 pints to a gallon. Since 100 gallons is the same as 800 pints, that is larger than 400 pints, Witch is also 50 gallons.

So ill say 100 gallons are bigger. :)

Please help..not too sure on how to work this out.

lina2011 [118]

Answer and Step-by-step explanation:

Ok, it's basically just parts of a circle circumference and area equation. Let's start first by writing down both equations.

C = 2πr

C = πd

A = π $r^{2}$

Now, all we have to do is plug in the values into those equations!

4. C = 2π(12) A = π( $12^{2}$ )

r = 12

d = 24 <---- (12 times 2 equals 24)

C = 24π

A = 144π <---- (12 times 12 (itself) equals 144)

5. C = π4.8 A = π( $4.8^{2}$ )

r = 2.4 <------- (4.8 divided by 2 equals 2.4)

d = 4.8

C = 4.8π

A = 23.04π <------- (4.8 times 4.8 equals 23.04)

6. 20π = 2πr A = π $r^{2}$

r = 10 <------- (20π divided by π and divided by 2)

d = 20 <------- (20π divided by π)

C = 20π

A = 100π <------- (10 times 10 equals 100)

7. C = 2πr 81π = π $r^{2}$

r = 9 <------- (81π divided by π and square rooted equals 9)

d = 18 <------- (9 times 2 equals 18)

C = 18π <------- (2 times 9 equals 18, times π)

A = 81π
