Ava picks a number greater than 3 tens 6 ones. The number is less than 52. It has more than 6 ones. What could the number be?

melisa1 [442]

<span>reater than 3 tens 6 ones" probably means greater than 36, so maybe it's 37, 38, 39, and so on, up to 51. "It has more than 6 ones" probably means that it's got 7 or more in the ones place. so 40, 41, up to 46, and 50 and 51 can't be it. So we're left with 37, 38, 39, 47, 48, or 49 as possibilities for what Ava picked.</span>

A random sample of n 5 4 individuals is selected from a population with m 5 35, and a treatment is administered to each individu

Firdavs [7]

Answer:

5.1

Step-by-step explanation:

Given that:

sample size n = 4

the mean of the original population μ is = 35

and the mean for the sample after treatment M is = 40.1

standard deviation of the sample SS = 48

The difference between the mean for the treated sample and the mean for the original population is therefore calculated as: M - μ

= 40.1 - 35

= 5.1

The standard error of M is = $\dfrac{standard \ deviation \ of \ the \ sample}{\sqrt{sample \ size} }$

The standard error of M is = $\dfrac{SS}{\sqrt{n} }$

The standard error of M is = $\dfrac{48}{\sqrt{4} }$

The standard error of M is = $\dfrac{48}{2 }$

The standard error of M is = 24

Suppose you would like to save P9000 invested at 8% compounded quarterly for 5 years and 6 months. (Note: Round off your answer

Sever21 [200]

Answer:

a) 13913

b) 4913.82

Step-by-step explanation:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

In this question:

Investment of 9000, so $P = 9000$
