Answer:
15.86%
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
Percent of area between the mean and 0.20 standard deviations from the mean:
pvalue of Z = 0.2 subtracted by the pvalue of Z = -0.2
Z = 0.2 has a pvalue of 0.5793
Z = -0.2 has a pvalue of 0.4207
0.5793 - 0.4207 = 0.1586
So this percentage is 15.86%
Answer:
f(x) = 86(1.01)^7x; They grow at approximately the rate of 1% per day.
Step-by-step explanation
86 is the number of weeds at the starting point of the question.
8/7% each day, 7 being the total number of days in the week, the weekly growth 8%: 1 day is 8/7% growth or 1.14% rounded up to 1%
In the original equation the 8% growth was represented by 1.08
Substituting the weekly rate of 8% with the daily rate of 1%, or 1.08 with 1.01 the new function is:
f(x) = 86(1.01)^7x

In △ABD and △ACD, we have
DB=DC ∣ Given
∠ADB=∠ADC ∣ since AD⊥BC
AD=AD ∣ Common
∴ by SAS criterion of congruence, we have.
△ABD≅△ACD
⇒AB=AC ∣ Since corresponding parts of congruent triangles are equal
Hence, △ ABC is isosceles.
