The tree was 30 feet tall. If we divide 33 by 1.1(undoing the 10% increase) we get 30. We can prove this by multiplying 30 by 1.1
Answer:18
Step-by-step explanation: cuz 1 = 7 so it is 18
I don't really understand your question. You claim he draws one piece of candy, then ask for the probability of a red gumdrop followed by a cinnamon candy. Regardless, I'll just answer the latter question (Assuming they're not replaced):
3+2+4+1 = 10
3/10 x 1/9 = 0.033333 or 1/30
Z = 1.555 should be used
If we seek an 88% confidence interval, that means we only want a 12% chance that our interval does not contain the true value.
Assuming a two-sided test, that means we want a 6% chance attributed to each tail of the Z-distribution.
the zα/2 value of z0.06.
This z value at α/2=0.06 is the coordinate of the Z-curve that has 6% of the distribution's area to its right, and thus 94% of the area to its left. We find this z-value by reverse-lookup in a z-table.
<h3>What is Z-distribution?</h3>
The standard normal distribution, also called the z-distribution, is a special normal distribution where the mean is 0 and the standard deviation is 1.
Any normal distribution can be standardized by converting its values into z-scores. Z-scores tell you how many standard deviations from the mean each value lies.
<h3>Why is z-score used?</h3>
The standard score (more commonly referred to as a z-score) is a very useful statistic because it
(a) allows us to calculate the probability of a score occurring within our normal distribution and
(b) enables us to compare two scores that are from different normal distributions.

Answer:
Step-by-step explanation:
Given
Required
Determine KL
From the given parameters, we understand that K is a point on J and L;
This implies that
Substitute values for JK, KL and JL
Collect Like Terms
To solve for KL, we simply substitute 3 for L in
Hence;
