Answer:
1%
Step-by-step explanation:
We need our two numbers to have the same units. Since one number is in cents and the other is in dollars, we should change one of them. It could be either one.
Both numbers in cents:
50/4000
OR, both numbers in dollars:
.50/40.00
Either of these will work. Divide, you will get a decimal answer. Then multiply by 100 to change to a percent.
50÷4000 (OR .5/40)
= 0.0125
times by 100
0.0125 × 100
= 1.25% but the directions said to round to the nearest whole number, that's 1%
First you must find x in order to solve this question, unless you do not need to find out X.
Answer:
Part A:
c = .86*p
c =1.72 for 2 lbs
Part B:
c =.81p
Step-by-step explanation:
Part A:
Total cost = cost per pound * number of pounds
c = .86*p
Let p = 2
c = .86*2
c =1.72
Part B:
Total cost = cost per pound * number of pounds
c = .(.86-.05)*p
c =.81p

Answer:
0.5
Step-by-step explanation:
Solution:-
- The sample mean before treatment, μ1 = 46
- The sample mean after treatment, μ2 = 48
- The sample standard deviation σ = √16 = 4
- For the independent samples T-test, Cohen's d is determined by calculating the mean difference between your two groups, and then dividing the result by the pooled standard deviation.
Cohen's d = 
- Where, the pooled standard deviation (sd_pooled) is calculated using the formula:

- Assuming that population standard deviation and sample standard deviation are same:
SD_1 = SD_2 = σ = 4
- Then,

- The cohen's d can now be evaliated:
Cohen's d =
