Answer:
(d) -0.253
Step-by-step explanation:
According to a z-score table for a standard normal distribution, a z-score of -0.25 corresponds to the 40.13th percentile, and a z-score of -0.26 corresponds to the 39.74th percentile.
Interpolating those values gives us the z-score for the 40th percentile. The 40.13th percentile is twice as close to the 40th percentile than the 39.74th, thus:
The answer is (d) -0.253.
Answer:
You did not show a picture so i can only help explain.
Step-by-step explanation:
When reflecting over the x-axis each point should have the same x coordinate and opposite y coordinate. For example from (9, 3) to (9, -3)
hope this helps!
For this case we first write the equation of which we will use:
I (db) = 10log (l / l)
We substitute the value of l.
We have then:
l = 10 ^ 8lo
Substituting in the given equation:
I (db) = 10log ((10 ^ 8lo) / lo)
Rewriting:
I (db) = 10 * log (10 ^ 8)
I (db) = 80
Answer:
I (db) = 80
option 4
Answer:
Emilias inequality, x<6 is correct because the number of hours is less than it equal to 6. Emilias number line is correct. The endpoint is correctly filled in and the number line should be shaded to the left of the endpoint.
Answer:
x= 10
Step-by-step explanation:
Tangent Chord Angle = 1/2 Intercepted Arc
7x-10 = 1/2(120)
7x-10 = 60
Add 10 to each side
7x = 70
Divide by 7
x = 10
