1.) 70

2.) 36.75

3.)126.65

Step-by-step explanation:

1.) .3 * 100 = 30

100 - 30 = 70

2.) .25 * 49 = 12.25

49 - 12.25 = 36.75

3.) .15 * 149 = 22.35

149 - 22.35 = 126.65

Joanne is making punch. She uses 1/2 gallon of orange juice, 3 quarts of

agasfer [191]

Answer:

1/2 gallon=2 quarts plus 3 quarts so 5 quarts then 11/4 would be 11 quarts so 11+2+3=16 quarts

Step-by-step explanation:

If the 11/4 part is confusing you on how many quarts it actually is it simply means that for every 4 quarts you get a gallon and you have 11 quarts so you can also look at it as 2 3/4 gallons if that somehow clarifies it.

Determine the number of degrees of freedom for the two-sample t test or CI in each of the following situations. (Round your answ

tekilochka [14]

Answer:

$df = 24.32$

$df = 30.10$

$df = 30.7$

$df = 25.5$

Step-by-step explanation:

Generally degree of freedom is mathematically represented as

$df = \frac{ [\frac{ s^2_i }{m} + \frac{ s^2_j }{n} ]^2 }{ \frac{ [ \frac{s^2_i}{m} ]^2 }{m-1 } +\frac{ [ \frac{s^2_j}{n} ]^2 }{n-1 } }$

Considering a

a) m = 12, n = 15, s1 = 4.0, s2 = 6.0

$df = \frac{ [\frac{ 4^2 }{12} + \frac{ 6^2 }{15} ]^2 }{ \frac{ [ \frac{4^2}{12} ]^2 }{12-1 } +\frac{ [ \frac{6^2}{15} ]^2 }{15-1 } }$

$df = 24.32$

Considering b

(b) m = 12, n = 21, s1 = 4.0, s2 = 6.0

$df = \frac{ [\frac{ 4^2 }{12} + \frac{ 6^2 }{21} ]^2 }{ \frac{ [ \frac{4^4}{12} ]^2 }{12-1 } +\frac{ [ \frac{6^2}{21} ]^2 }{21-1 } }$

$df = 30.10$

Considering c

$df = \frac{ [\frac{ 3^2 }{12} + \frac{ 6^2 }{21} ]^2 }{ \frac{ [ \frac{3^4}{12} ]^2 }{12-1 } +\frac{ [ \frac{6^2}{21} ]^2 }{21-1 } }$

$df = 30.7$

Considering c

(d) m = 10, n = 24, s1 = 4.0, s2 = 6.0

$df = \frac{ [\frac{ 4^2 }{10} + \frac{ 6^2 }{24} ]^2 }{ \frac{ [ \frac{4^2}{10} ]^2 }{10-1 } +\frac{ [ \frac{6^2}{24} ]^2 }{24-1 } }$

$df = 25.5$

How do you graph (-9,5 8)

dusya [7]

Step-by-step explanation:

If you have a co-ordinate plane with you, it will greatly help.

First, move -9.5 units to the left.

Then, move 8 units up.

You will most likely land on a line. If you don't, try it again.

If you do, put your point right there!
