Answer: H' = (-4, 4)
<u>Step-by-step explanation:</u>
H = (-4, -4)
reflect across y = -2:
H is 2 units below y = -2 so when reflected it will be 2 units above y = -2
--> t<em>he x-coordinate doesn't change</em> the new y-coordinate is: 0
H' = (-4, 0)
reflect across y = 2:
H' is 2 units below y = 2 so when reflected it will be 2 units above y = 2
--> t<em>he x-coordinate doesn't change</em> the new y-coordinate is: 4
H'' = (-4, 4)
Answer:
B and C
Step-by-step explanation:
To determine which ordered pairs are a solution, substitute the coordinate points into the left side of the inequality and check against right side for validity.
A (3, 5)
25 - 9 = 16 ≥ 7 ⇒ (3, 5) is not a solution
B (- 2, - 5)
- 25 + 6 = - 19 ≤ 7 ⇒ (- 2, - 5) is a solution
C (5, - 3)
- 15 - 15 = 0 ≤ 7 ⇒ (5, - 3) is a solution
Answer:
0.3
Step-by-step explanation:
Given: The odds of winning a contest are 3:7
To find: probability of winning the contest
Solution:
Probability refers to chances of occurrence of an event.
Odds are defined as (chances for success) : (chances against success)
Probability of winning = (chances for success) : (chances for success + chances against success)
As odds of winning a contest are 3:7,
(chances for success) : (chances against success) = 3:7
So,
Probability of winning the contest =
Answer:
The z-scores are and
Step-by-step explanation:
From the question we are told that
The middle of the distribution area considered is 48%
Now the rest of the area under the standard normal distribution area is mathematically evaluated
Now to obtain the area occupied by this proportion at the two tails we divide by 2 i.e
Now the z-score is obtained from the normal distribution table and the value is
The shows that we are considering the two-talil
