What is the scale factor of triangle ABC to triangle DEF?

Mathematics
1 answer:
8_murik_8 [283]3 years ago
5 0

Answer:

Second option, scale factor is 2.5

Step-by-step explanation:

We see that ∠B ≅ ∠E and ∠C ≅ ∠F, therefore, ΔABC ~ ΔDEF by the AA Similarity for Triangles Theorem which states that if two pairs of corresponding angles are congruent in two triangles, then those two triangles are similar. To find the scale factor, all we have to do is DF / AC = 5/2 or 2.5.

How do you do mathematical inductions?!
EastWind [94]

THE NATURAL NUMBERS are the counting numbers:  1, 2, 3, 4, etc.Mathematical induction is a technique for proving a statement -- a theorem, or a formula -- that is asserted about every natural number.

By "every", or "all," natural numbers, we mean any one that we might possibly name.


Hope this helps.

Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x is greater than or equal to 86)? A. 0.
Lina20 [59]

Answer

0.975 is the probability value

Step-by-step explanation:

We start by getting the z score of 86

z-score = (x - mean)/SD

z-score = (86-98)/6 = -12/6 = -2

So we want to find the probability of z greater than or equal to 2

We shall be using the standard normal distribution table here

We have the answer as;

0.975
