An experiment was done to study how different sandwich fillings might affect the mean number attracted to pieces of a sandwich the students running this experiment also varied the type of bread for the sandwiches randomizing between four types: Multigrain, Rye, Wholemeal, and White. The ant counts in 6 trials and summary statistics for each type of bread and the 24 trials as a whole are given in Table 1 and stored in SandwichAnts. a. use the summary information to compute the three sums of squares needed for using ANOVA to test for a difference in mean number of ants among four types of bread. Round your answers to one decimal place. SGG: SSE:
SSTotal
b. Use the sums of squares from part ( a) to construct the NOVA table and complete the details for this test. Fill in the following ANOVA table. Enter exact answers for degree of freedom, round your answer for the F-statistic to two decimals places, and round all other answers to one decimal place. What is the p- value? Round your answer to three decimal places.
What is the conclusion of the test?
Is there evidence of a difference in a mean number of ants based on bread type?

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
