Pumpkin patch: suppose we plant pumpkins in a garden where half of the plants are shaded. then, to test a new fertilizer, we fertilize the plants in full sun and do not fertilize the plants in the shade. in the fall the fertilized plants yield more, bigger, and prettier pumpkins.
which of the following did we fail to include in the experimental design?
(1) establish a control group
(2) direct control of confounding variables
(3) compare groups of the explanatory variable
(4) establish measurable outcomes to determine the effectiveness of the explanatory variable

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

d: 0.7(t + 4 + 2) = t .
