Answer:
x1=3 x2=-5
BUT x1=3 is not an answer because it doesnt respects the range on the original ecuation, so x2=-5 is the solution
Step-by-step explanation:
We know, Area = Length * Width
So, with area 42, dimensions could be: 1 * 42
2 * 21
3 * 14
6 * 7
Just draw the lines with that measures, two pair of two equal opposite lines.
Hope this helps!
Answer:
Cross Multiply.
Step-by-step explanation:
Multiply the denominator (3) of one side and the numerator (n).
Then, multiply the numerator (2) of on side and the denominator (4) of the other.
3n = 8
You divide both sides by 3 to have n be by itself, equaling ~2.6 or 8/3.
Answer:
In this case, a sample was taken and an hypothesis test was done. The P-value of the test is 0.0016.
a) With this P-value, the null hypothesis will be rejected. That means it will be considered false with statistical evidence.
If the null hypothesis is true, and it is rejected, we will have what is called a Type I error (rejecting the null hypothesis when it is true).
The probability of this error depends from the significance level (the higher the significance level, the higher the probability of a Type I error).
b) This P-value is obviously smaller than any significance level. That means that the effect is statistically significant and there is evidence to reject the null hypothesis, whatever it was.
Step-by-step explanation:
Answer: c = 20/10
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
We have to divide the number of carrots (20) by the number of bunnies (10).That expression must be equal to the number of baby carrots that each bunny gets (c)
Mathematically speaking:
c = 20/10
