We have compound interests, so:

$a_1=600\\\\r=4\%=0.04$

and:

$A(n)=a_1(1+r)^{(n-1)}\\\\\boxed{A(n)=600(1+0.04)^{(n-1)}}\\\\\\A(5)=600(1+0.04)^{(5-1)}=600(1.04)^{4}=600\cdot1.17\approx\boxed{701.92}$

Answer B.

Suppose a normal distribution has a mean of 38 and a standard deviation of

Sauron [17]

Answer:

77.4% probability that a data value is between 36 and 41

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

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:

$\mu = 38, \sigma = 2$

What is the probability that a data value is between 36 and 41?

This is the pvalue of Z when X = 41 subtracted by the pvalue of Z when X = 36.

X = 41

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{41 - 38}{2}$

$Z = 1.5$

$Z = 1.5$ has a pvalue of 0.933

X = 36

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{36 - 38}{2}$

$Z = -1$

$Z = -1$ has a pvalue of 0.159

0.933 - 0.159 = 0.774

77.4% probability that a data value is between 36 and 41

Meg cycles 6.2 km every morning. How many feet are in 6.2 km, given that 1 mile= 1.609 km and 1 mile= 5280ft

Nikolay [14]

Answer:

<em>There are 20345.556... feet in 6.2 km.</em>

Step-by-step explanation:

Given that, 1 mile = 1.609 km and 1 mile = 5280 ft.

<u>That means we can say</u>, 1.609 km = 5280 ft.

So, 1 km = $(\frac{5280}{1.609})ft = 3281.541... ft$

Now, for converting 6.2 km into feet, we will <u>just multiply 6.2 by 3281.541... ft</u>.

Thus, 6.2 km = $(6.2 \times 3281.541...)ft = 20345.556... ft$

So, there are 20345.556... feet in 6.2 km.
