Alex invests his money in an account paying 2% interest compounded semiannually. What is the effective annual yield on this acco
Travka [436]

Answer: 2.01%.

Step-by-step explanation:

Suppose Alex invests $1 into the account for one year. The formula is A=P0⋅(1+rk)N⋅k with P0=$1. We know that r=0.02 and k=2 compounding periods per year. Now, N=1 year. Substituting the values we have A=$1⋅(1+0.022)2=$1.0201. Now, to calculate the effective annual yield, we will use the formula rEFF=A−P0P0. rEFF=1.0201−11=0.0201 or 2.01%. When rounded to two decimals, rEFF=2.01%. However, do not include the % in your answer.

Pre image ABCD was dilated to be image A’B’C’D, where the center of dilation is the origin. What scale factor was used in the di
ArbitrLikvidat [17]

Answer:

The scale factor is 0.25

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

ABCD and A'B'C'D' are similar

therefore

\frac{A'B'}{AB}=\frac{B'C'}{BC}=\frac{C'D'}{CD}=\frac{A'D'}{AD}

Find the scale factor

Looking at the graph

we have

A'B'=1\ unit\\AB=4\ units

Let

z ---> the scale factor

z=\frac{A'B'}{AB}

substitute the values

z=\frac{1'}{4}=0.25

An observational study determined that there is a strong correlation between getting less than 8 hours of sleep a day and lower
s2008m [1.1K]

Answer:

No

Step-by-step explanation:

We can not determine that the low test scores are caused by sleep deprivation. Because there are many factors that can affect on a student's test score such as:

  • not carefully review all the lesson before the test
  • the feeling of nervous in the exam room
  • poor academic ability
  • ....so on

So, getting less than 8 hours of sleep is just one of the independent variables determining the test score, it is not a strong correlation.
