Answer:
No I disagree, because he had 34 bottles of water at the start but, when he finished he only has 1 left. 34-1=33 so in reality he drank 33 bottles of water.
Step-by-step explanation:
$21.00
let the original price = 100%
then the discount price = 100 - 15 = 85%
divide $17.85 by 85 to obtain 1% then multiply by 100 to obtain original price.
original price = $17.85 × = $21
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 =
0=40-10t-5t^2
t^2+2t-8=0
(t+4)(t-2)=0
t=-4 (not a solution) or t=2
