When a poultry farmer uses his regular feed, the newborn chickens have normally distributed weights with a mean of 61.1 oz. In an experiment with an enriched feed mixture, ten chickens are born with the following weights (in ounces). 66.1, 64.7, 65.3, 68.5, 65.7, 64.7, 61.3, 66.1, 67.2, 65.6Use the α=0.01 significance level to test the claim that the mean weight is higher with the enriched feed. The sample mean is x⎯⎯⎯= The sample standard deviation is s= The test statistic is t= The critical value is t=

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

actually what is a question i don't understand
