Answer:
OBTUSE
Step-by-step explanation:
We can determine this based on the the pythagorean theorem!
[tex]a^{2}+ b^2 = c^2[/tex]
With Pythagorean Theorem, c is the longest length in the triangle... So, if c = a squared plus b squared, then it is a right triangle! If c is less, it is acute, and finally, if C is more than the two - then it is obtuse!
So let's see...
[tex]8^{2} +6^2 ? 12^2\\64 + 36 ? 144\\100 < 144[/tex]
This is an OBTUSE triangle, since c adds up to be more than a and b.

One year, the population of a city was 80,000. Several years later it was 66,400. Find
the percent decrease.
Answer:
The population decrease by 17%.
Step-by-step explanation:
This is because 66,400 is 83% of 80,000.
100%-83%= 17%
Therefore, the percentage of the population that decreased was 17%

Answer:
m<1 = 62°
m<2 = 45°
m<3 = 24°
Step-by-step explanation:
Hi!
Let me walk you through it!
The first step is to find angle 1.
Angle 1 is supplementary with the angle 118°
So we do 180° - 118° = 62°
m<1 = 62°
Then we find angle 2.
There are two ways to do this
The sum of interior angles in a triangle is 180°
So we do 180° - (73 + 62°)
Open parenthesis:
180° - 73° - 62° = 45°
You can also use the exterior angle theorem
118° = 73° + m<2
Same to both sides:
45° = m<2
So
m<2 = 45°
Now, using this information, we can find angle measure 3.
Now we look at the big triangle. Again, there are two ways to do this.
First way:
m<1 + 49° + m<2 + m<3 = 180°
Plug in known-values
62° + 49° + 45° + m<3 = 180°
Combine like terms:
156° + m<3 = 180°
Same to both sides:
m<3 = 24°
Second way:
Exterior angle theorem.
118° = m<2 + m<3 + 49°
Plug in known-values:
118° = 45° + m<3 +49°
Combine like terms:
118° = 94° + m<3
Same to both sides:
24° = m<3
So m<3 = 24°
There you go! You just need to take it step-by-step and you can get the answer. Be open-minded, don't just try to go for a certain angle, see what you can do, and work from there. It all comes together at the end.

Omar ordered his sister a birthday card from a company that randomly selects a card from their inventory. The company has 21 total cards in inventory. 14 of those cards are birthday cards. What is P(not a birthday card)
Answer:
P = 7
Step-by-step explanation:
We have 21 total cards and out of those 21 cards, 14 of those are birthday cards. So that means that the amount of cards that are not birthday cards is the number of cards subtracted by the number of birthday cards, also shown as 21 - 14. So 21 - 14 = P, so now we solve what 21 - 14 is which is 7, so that means P = 7.

An airline claims that its average taxi time is 15 minutes, and the standard deviation is 1.4 minutes. The taxi time has a bell/mound shape distribution. On a flight with this airline, you observe that the taxi time is 18 minutes. Calculate the z score for your flight's taxi time. Round the final answer to 2 decimal places.
Answer:
The z score for your flight's taxi time is of 2.14.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
An airline claims that its average taxi time is 15 minutes, and the standard deviation is 1.4 minutes.
This means that [tex]\mu = 15, \sigma = 1.4[/tex]
On a flight with this airline, you observe that the taxi time is 18 minutes. Calculate the z score for your flight's taxi time.
This is Z when [tex]X = 18[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{18 - 15}{1.4}[/tex]
[tex]Z = 2.14[/tex]
The z score for your flight's taxi time is of 2.14.
You can convert the variate which tracks heights of trees to standard normal variate. That value of standard normal variate is called the z score and shows the area of the considered area in the plot of the standard normal distribution.
The z score for our flight's taxi time is approx 2.14286
How to convert a normal distribution variate to standard normal distribution variate?Suppose you have got a normal distribution variate with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] (let the variate is denoted by X), then we have
[tex]X \sim N(\mu, \sigma)[/tex]
To convert it to standard normal distribution with mean 0 and the standard deviation as 1 ( [tex]Z \sim N(0,1)[/tex] ), we have:
[tex]Z = \dfrac{X - \mu}{\sigma}[/tex]
For the given case we have:
Let the average taxi time be tracked by random variable X, then, as the mean time is 15 minutes, and the standard deviation 1.4 minutes , thus,
[tex]X \sim N(15, 1.4)[/tex]
Converting it to standard variate:
[tex]Z = \dfrac{X - 15}{1.4}[/tex]
Since the observed taxi time was 18 minutes, thus, we have X = 18,
Getting the z score:
[tex]Z = \dfrac{18 - 15}{1.4} = \dfrac{3}{1.4} \approx 2.14286[/tex]
Thus,
The z score for our flight's taxi time is approx 2.14286

The triangle below is reflected over the line x = 4.
Which transformation(s) would produce the same image?
2676$10
A Reflecting over the x-axis and then translating to the right 4 units
B. Reflecting over the y-axis and then translating to the right 4 units
C Reflecting over the y-axis and then translating to the right 8 units
D Reflecting over the x-axis and then translating to the right 8 units
9514 1404 393
Answer:
C. Reflecting over the y-axis and then translating to the right 8 units
Step-by-step explanation:
Reflection over the line x=4 gives you the transformation ...
(x, y) ⇒ (2·4 -x, y) = (-x +8, y)
This is precisely the same transformation you get by reflection over the y-axis:
(x, y) ⇒ (-x, y)
followed by translation to the right 8 units:
(-x, y) ⇒ (-x +8, y)
__
Reflection over x=4 is the same as reflection over y and translation right 8.
