Answer:
Each employee took home 1/4 of pizza each.
Step-by-step explanation:
1. Picture a pizza as being a full 100%.
2. Since each employee took home the same amount of pizza, you need to divide the pizza equally by 4. 100 ÷ 4 = 25 this also equals 25/100
3. To reduce the fraction 25/100, you have to find a number that both the numerator and denominator can be divided by.
4. In this scenario, 25/100 can both be divided by 25.
5. 25 ÷ 25 = 1 100 ÷ 25 = 4
6. Therefore the final answer is each employee took home 1/4 of the pizza.
Answer:
The correct answer is -
a. the second group that receives test medicine
b. the first group that receives an inert pill
c. double-blind
d. placebo-controlled experiment
Step-by-step explanation:
a. The treatment group is the group that is used to test the experiment or change and receives the desire independent variable which is the second group that receives the test medicine along with an exercise and diet plan.
b. The control group is the group that is placed in ideal condition and receives no change other than placebo, here, the first group receives an inert pill along with the same exercise and diet plan.
c. Here neither the patients nor the fitness and nutrition advisors know which one is the control group and which one is the treatment group so ts a double-blind group.
d. This is best described as a placebo-controlled experiment due to the fact that there is a control group in this experiment that receives a placebo and another group that receives the treatment.
A= (a+b)/2*h
A=(12+15)/2*5
A=(27/2)*5
A=13.5*5
A=67.5in
the domain is all the real numbers, or (-infinite <x<infinite)
the range is y>=-4
axis of symetry is x= -1
vertex is (-1,-4)
the parabola opens upwards
x intercepts (-3,0) and (1,0)
y intercepts (0,-3)
Answer:
Step-by-step explanation:
1/9
(1*4) / (9*4) = 4/36
(1*4) / (9*4) = 5/45
The first one is the ratio as it is stated in the problem.
The second one multiplies top and bottom by 4
The third one multiplies top and bottom of the top ratio by 5.
