Answer : The correct answer is, -13000 g
Explanation :
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The given expression is:
As we know that,
True value means, the rounding off the number. So,
Therefore, the correct answer is, -13000 g
Answer:
The correct option is:
A. We are 95% confident that the interval from 55.4 seconds to 61.2 seconds actually does contain the true value of μ.
Explanation:
In statistics, confidence interval is the interval estimate about the population parameter of interest at certain level of confidence like 95%. A 95% confidence interval gives us a range of values that we can be 95% confident contains the true mean of the population.
Therefore, the option A is correct

Answer:
80 gifts
Step-by-step explanation:
Maddison hid 12 of her sister's birthday gifts around the house. If this was 15% of the gifts, how many total gifts did her sister have?
Let the Total gifts that her sister has be represented by x
Hence:
15% of x = 12
15/100 × x = 12
15x /100 = 12
Cross Multiply
15x = 100 × 12
15x = 1200
x = 1200/15
x = 80 gifts
Hence, the total gifts her sister has is 80 gifts
