We formulate the null and alternative hypothesis here to state that battery life of the laptop lasts at least 12 hours(more than but not less, null hypothesis) or that it lasts less than 12 hours(alternative hypothesis).
The null hypothesis is the one being tested to know whether we would reject it or not in which case we choose the alternative hypothesis. To test the hypotheses, we do a t test using a significance level of say 0.05(95% confidence interval) and find our p value in order to compare and decide if the null hypothesis would be rejected or not based on statistical significance.
Hey there,
Your question states: <span>A customer went to a garden shop and bought some potting soil for $11.50 and 9 shrubs. The total bill was $94.75. Write and solve an equation to find the price of each shrub.
So, I will do 94.75 minus 11.50 because he bought nice scrubs so that would be 83.25.
I will do 83.25 divided by 9 because that's the number that person bought, each scrub will end up to be 9.25.
Hope this helps.

Answer:
3 (5x+7) = 75
15x + 21 = 75
15x + 21 - 21 = 75 - 21
15x = 54
x = 3.6
Step-by-step explanation:
The answer is 2/5. (Do not brainliest)
Given,
0.47
X= 0.47
10x = 4.7
100x = 47.7
90X = 43
X = 43/90
p/q= 43/90
