Answer:
All the coordinates are changed to
(x, y) ⇒ (2x, 2y)
Step-by-step explanation:
Given - A triangle is to be dilated with the origin as the center of dilation and with a scale factor of 2.
To find - Which answer choice correctly maps this dilation algebraically?
Proof -
Let ABC is a triangle where A, B, C are the vertices of the triangle respectively.
Now,
Let the coordinates be (x, y)
If a triangle is to be dilated with the origin as the center of dilation and with a scale factor of a , then the coordinated be changes as
(x, y) ⇒ (ax, ay)
Here given , a = 2
So, all the coordinates are changed to
(x, y) ⇒ (2x, 2y)
Answer:
option A: 0.2357
Step-by-step explanation:
P( less than 1.76 or greater than 2.39) = P(X < 1.76) + P( X > 2.39)
P(X < 1.76) = 0.0126 (as per the excel output)
P(X < 2.39) = 0.7769
Hence P( X> 2.39) = 1- 0.7769 = 0.223
P( less than 1.76 or greater than 2.39) = P(X < 1.76) + P( X > 2.39) = 0.0126 + 0.223 = 0.2357
P( less than 1.76 or greater than 2.39) = 0.2357
Answer:
4\7
Step-by-step explanation:
(2 1\2) \ (4 3\8)
first simply simplify the fractions so that we will get:
(5\2) \ (35\8)
with more simplifying we get:
(5 x 8) \ (2 x 35) = 4\7 = 0.57
Answer:
x = 12
Step-by-step explanation:
First you need to use the distributive property.
19 = 9 + 2x - 14
Then you should simplify (9-14)
19 = 2x - 5
+5 +5 (Then add 5 to both sides)
24 = 2x
/2 /2 (Divide by 2 to get x by itself)
12 = x
