Answer:
the expression is not factorable with rational numbers.
Since both y’s are negative you can combine them to make -6y=1 then you divide -6 on each Side to get y=6
Answer:
The steps 1-7 have been explained
Step-by-step explanation:
The steps are;
1) We will verify that the population standard deviations are known and that the population is normally distributed which means the sample size must be a minimum of 30.
2) We will state the null and alternative hypothesis
3) We will determine the critical values from the relevant tables
4) From the critical values gotten, we will determine it's corresponding region where it can be rejected.
5)We will calculate the value of the test statistic from the formula;
z = [(x1' - x2') - (μ1 - μ2)]/√[((σ1)²/n1) + ((σ2)²/n2)]
6) If the value of the test statistic gotten from step 5 above falls in the region of rejection noted in step 4,then we will reject the null hypothesis
7) After rejection of the null hypothesis, we will now give a decision/conclusion on the claim.
Answer:
Step-by-step explanation:
4(8+2n) = 4 + 4n
32 + 8n = 4+4n
4n = -28
n = -7
Answer:
The correct answer is:
"To inform readers about a topic using facts and details"
Step-by-step explanation:
Let us define informational writing first.
Informational writing is like communication writing which is used to convey something using facts and figures. Whatever is stated in an informational writing, it is supported by related facts and proofs.
Hence,
The correct answer is:
"To inform readers about a topic using facts and details"
