If the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs” what is the alternate hypothe

AlexFokin [52]

Answer:

“The true mean weight of the piglets is at most 39lbs”would be the alternate hypothesis.

Step-by-step explanation:

Given that the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”

We have to find the alternate hypothesis.

In hypothesis testing, alternate is the opposite of null hypothesis. If null hypothesis supports one statement alternate hypothesis opposes it. In other words, alternate hypothesis would be the negative of the claim of null hypothesis.

Here the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”

i.e H0: $x bar\geq 39 lbs$

So alternate hypothesis

Ha: $x bar\leq 39 lbs$

What is the soulution of a+ 5 2/3=9

mafiozo [28]

A + 5 2/3 = 9
a + 17/3 = 9
move the 17/3 over to the other side by subtraction (will need to find a common denominator)

a = 10/3

Hope this helps

Drag the tiles to the boxes to form correct pairs

$( - \frac{3}{4} )( \frac{7}{8} )$

$= \frac{ - 3}{4} \times \frac{7}{8}$

$= \frac{ - 21}{32}$

_______________________________________

$( \frac{2}{3} )( - 4)(9)$

$= \frac{2}{3} \times - 4 \times 9$

$= \frac{ - 72}{3}$

$= - 24$

_______________________________________

$( \frac{5}{16} )( - 2)( - 4)( - \frac{4}{5} )$

$= \frac{5}{16} \times - 2 \times - 4 \times \frac{ - 4}{5}$

$= \frac{ - 160}{80}$

$= \frac{ - 16}{8}$

$= - 2$

_______________________________________

$(2 \frac{3}{5} )( \frac{7}{9} )$

$= \frac{13}{5} \times \frac{7}{9}$

$= \frac{91}{45}$

-7 2/3 +(5 1/2) + 8 3/4 =

drek231 [11]

Answer:

6 7/12

Step-by-step explanation:

-7 2/3 +(5 1/2) + 8 3/4

Get a common denominator of 12

-7 2/3 * 4/4 +(5 1/2 +6/6) + 8 3/4*3/3

-7 8/12 + 5 6/12 + 8 9/12

Subtract the first two terms first

They have opposite signs so subtract and take the sign of the larger

-7 8/12 + 5 6/12 = -2 2/12

-2 2/12 + 8 9/12

They have opposite signs so subtract and take the sign of the larger

-2 2/12 + 8 9/12 = 6 7/12
