Nope in fact its C scalene
two sides are the same and tge third is different
Answer:
$80
Step-by-step explanation:
40 increase 100% =
40 × (1 + 100%) = 40 × (1 + 1) = 80
The first one for the first y-intercept number is -1.
The second one is 5. (Not negative)
The third one is 11 (Not negative)
The fourth one is just 11 (Not negative as well)
The ones that say Not negative means that those numbers are postive.
I hope this helps though! :D
Hello!
Let's set this up as a proportion.
.
We cross multiply, giving us the equation below.
52x=11760
We divide both sides by 52.
x≈226.15
Therefore, it travels about 226.15 mph.
I hope this helps!
Answer:
a) H0: p1 - p2 = 0
H1: p1 - p2 ≠ 0
b) z=-0.58
c) p-value = 0.562
Step-by-step explanation:
We need to determine whether p1 is not equals p2, so the null and alternative hypothesis are:
H0: p1 - p2 = 0
H1: p1 - p2 ≠ 0
Where p1 and p2 are the proportions of the population. Additionally, the proportions of the sample p1' and p2' are calculated as:
Then, the test statistic is calculated using the following equation:
Where p' is calculated as:
So, replacing the values, we get that the test statistic is:
Finally, using the standard normal table, the p-value is equal to:
The p-value is greater that the value of alpha 0.1, so we can't reject the null hypothesis and there is evidence to said that p1 and p2 are equals.
