Answer:
No solutions
Step-by-step explanation:
31 times any positive number cannot be a negative number.
7+18/(6-3)
7+18/3
25/3=8.333
Answer:
3² or 9
Step-by-step explanation:
Step 1: Add exponents

Step 2: Subtract exponents
You should get 3² because of exponent rules. Remember when you multiply exponents you add the powers and when you divide exponents you subtract the powers.
Answer:
a) 0.3571
b) The p-value is 0.362007.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 1.35
Sample mean,
= 1.4
Sample size, n = 26
Alpha, α = 0.01
Sample standard deviation, s = 0.7
First, we design the null and the alternate hypothesis
We use One-tailed t test to perform this hypothesis.
a) Formula:
Putting all the values, we have
b) The p-value at t-statistic 0.3571 and degree of freedom 25 is 0.362007.
I dont know if this is right but the answer to 2(12+8x)-3(4x-9) might be 4x+51?
