Answer:
A) The ratio of hypotenuse to base for the triangles is 0.75
Step-by-step explanation:
Here, the given question is INCOMPLETE.
The following two triangles have the same angles, and are similar. What is the ratio of height to base for the triangles?
A) .75
B) 1.00
C) 1.25
D) 2.50
Here, given that the two triangles are similar.
In triangle one:
Height = 6 units , Base = 8 units
In triangle one:
Height = 3 units , Base = 4 units
Now,as the two given triangles are similar.
⇒Their corresponding sides are PROPORTIONAL.
So, in both the triangles, the corresponding side ratio is 0.75.
Hence, the ratio of hypotenuse to base for the triangles is 0.75
Answer:
0.13591.
Step-by-step explanation:
We re asked to find the probability of randomly selecting a score between 1 and 2 standard deviations below the mean.
We know that z-score tells us that a data point is how many standard deviation above or below mean.
To solve our given problem, we need to find area between z-score of -2 and -1 that is .
We will use formula to solve our given problem.
Using normal distribution table, we will get:
Therefore, the probability of randomly selecting a score between 1 and 2 standard deviations below the mean would be 0.13591.
