If you are setting it up as a proportion then you would muiltiply the 12 and x to get 12x. Then muiltiply the 80 and 1 to get 80. So 12x=80. Divide the 12 to get your final answer
7.6 x 1/10^5
=7.6 x 1/100,000
=0.000076

Answer:
The final temperature of the solution was 5°C
Step-by-step explanation:
we know that
1) At the start of an experiment, the temperature of a solution was -12°C
In this moment the temperature is -12°C
2) During the experiment, the temperature of the solution rose 5°C each hour during 4 hours
so
5°C*4=20°C
In this moment the temperature is -12°C+20°C=8°C
3) The temperature changed by -3°C
In this moment the temperature is 8°C-3°C=5°C
Answer:
2 independent sample t test
Step-by-step explanation:
This test is also called the two sample t-test. This test is an inferential yet which is used to know if a significant difference exists statistically in 2 unrelated groups.
In this question, we have 2 different soda brands. These 2 brands are to be rates in a random order. The hypothesis test that is best for this is the 2 independent sample t-test.
