Answer:
squid, crab, tuna, eel
Step-by-step explanation:
Just make each sushi piece into an equation, then solve it.
For example, for the squid: (s stands for squid)
Divide both sides by 2 to get "s" by itself
Eel: (e stands for eel)
e = 3.25
Tuna: (t stands for tuna)
Divide both sides by 3 to get "t" by itself
Crab: (c stands for crab)
Divide both sides by 4 to get "c" by itself
**Then order from least to greatest**
50 ft because you times 20 by 40 then you divide by 100 because that is the total percent
Answer:
The 95% confidence interval for the mean score of all such subjects is (32.033, 120.367).
Step-by-step explanation:
We have the sample standard deviation, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of
. So we have T = 2.039
The margin of error is:
M = T*s = 2.0639*21.4 = 44.167
In which s is the standard deviation of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 76.2 - 44.167 = 32.033
The upper end of the interval is the sample mean added to M. So it is 76.2 + 44.167 = 120.367
The 95% confidence interval for the mean score of all such subjects is (32.033, 120.367).
Answer:
9/6 or 3/2 or 1 1/2
Step-by-step explanation:
Do distributive property to get rid of the parenthesis
4x + 2x + 3 = 12
combine like terms
6x + 3 = 12
move the 3 over by subtraction
6x = 9
divide by 6
x = 9/6 or 3/2 or 1 1/2
