Monica deposited $26000 in an account that pays 4% interest compounded annually. How much money does she earn after 10 years?
1 answer:
Heres the formula for compound interest:
A=P(1+
)^nt
A is the amount over 10 years
P is the initial deposit ($26,000)
r is the annual interest rate (4% or .04)
n is the number of times that interest is compounded annually (1)
t is the number of years the money is invested (10 yrs)
A=26000(1+
)^(1)(10)
A=26000(1.04)^10
A=26000(<span>1.48024428492)
A=$</span><span>38,486.3514079
(Simplified she would have $38,486.35)</span>

Answer:
19.77% of average city temperatures are higher than that of Cairo
Step-by-step explanation:
Problems of normally distributed samples are solved using 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.
In this question, we have that:
What percentage of average city temperatures are higher than that of Cairo?
This is 1 subtracted by the pvalue of Z when X = 21.4.
has a pvalue of 0.8023
1 - 0.8023 = 0.1977
19.77% of average city temperatures are higher than that of Cairo
Answer:
y = -1/6x + 5
Step-by-step explanation:
y = mx + c
Gradient (m) = -1/6
Y-intercept (c) = 5
so
y = -1/6x + 5
