Answer:
Option B is correct.
Step-by-step explanation:
Otero translated the phrase "three less than a number" into the expression 3 - x.
I think Otero gave a wrong expression for the phrase.
The true interpretation of the phrase is that if we assume the number as x then three less than a number means x - 3.
Therefore, Otero's expression is inaccurate. Three is being subtracted from a number, so x-3 is what he should have written. (Answer)
This is already in factored form.
I think you meant to say USE FOIL.
(a-b)(a-b^2)
a^2 -ab^2 - ab + b^3
Done.
Wind speed: 100 miles per hour
300 times 6 = 1800 miles so it took 6 hours to travel 1800 miles. 1800 minus 1200 miles = 600 miles. you lost 600 miles over 6 hours or 100 miles per hour
Answer:
12.3
Step-by-step explanation:
-8 1/2+-3.8=12.3
Answer:
H0 : μ ≤ x
H1 : μ > x
The hypothesis :
The null hypothesis, H0 : μ ≤ x
The alternative hypothesis, uses the Friday score samples to compare the hypothesis ;
The alternative hypothesis, H1 : μ > 8
For then null, the mean scores is assumed to be the same, and has such mean of Friday's test score takes the value of the population.
Let the population mean value = x
The alternative hypothesis is the claim that the sampled mean gives a greater value than the population mean :
H1 : μ > x
