the answer is a-11
Step-by-step explanation:
f(x)=2x+3
f(4)=2(4)+3
f(4)=8+3
f(4)=11
Answer:
The price that is two standard deviations above the mean price is 4.90.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 3.22 and a standard deviation of 0.84.
This means that
Find the price that is two standard deviations above the mean price.
This is X when Z = 2. So
The price that is two standard deviations above the mean price is 4.90.
Step-by-step explanation:
AB=hypotenuse,BC=adjacent, AC=opposite
<u>PYTHAGOREAN</u><u> </u><u>THEOREM</u><u>=</u><u>a</u><u>^</u><u>2</u><u> </u><u>=</u><u>b</u><u>^</u><u>2</u><u> </u><u>+</u><u>c</u><u>^</u><u>2</u>
if ca =q and cb =p
THEN:aq^2 +bp^2=ab^2+qp^2
Here, The translation is up 8 units & no effect in Horizontal zone (means in x-axis) so it would remain same.
& (x, y) → (x, y+8)
In short, Your Answer would be Option B
Hope this helps!
