$6000 are invested in a bank account at an interest rate of 10 percent per year.

Licemer1 [7]

The amount for the investment of $6000 will be a.$6369 b. $6090 and c.$6030.

<h3>What is compound interest?</h3>

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

$A=P[1+\dfrac{r}{n}]^{nt}$

a) The amount in the bank after 6 years if interest is compounded annually.

$A=P[1+\dfrac{r}{1}]^{t}\\\\\\A=6000[1+\dfrac{0.01}{1}]^{ 6}$

A= $6369

b) The amount in the bank after 6 years if interest is compounded quarterly.

$A=P[1+\dfrac{r}{4}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{4}]^{4\times 6}$

A= $6090

c ) The amount in the bank after 6 years if interest is compounded monthly.

$A=P[1+\dfrac{r}{12}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{12}]^{12\times 6}$

A=$6030

Hence the amount for the investment of $6000 will be a.$6369 b. $6090 and c.$6030.

Which characteristics describe the scatterplot? check all that apply.

FrozenT [24]

The characteristics described in the scatterplot are B. positive correlation D. weak association E. linear.

<h3>What are the condition for Correlation?</h3>

1. Negative Correlation:

The correlation is achieved when either or both values of x and y on the graph decrease.

2. Positive Correlation

The correlation is achieved when the slope (value) of both x and y increases.

3. Strong Correlation

This is achieved when there's uniformity in slopes x and y.

4. Weak Correlation

This is achieved when there are no uniforms in slopes x and y

5. Linear

Linearity is achieved when the data pattern is linear (straight)

6. Nonlinear

Non-Linearity refers to whether a data pattern is curved.

We can see that the characteristics described in the scatterplot are B. positive correlation D. weak association E. linear.

What would be the critical value for a two-tailed, one-sample t test with 26 degrees of freedom (df = 26) and an alpha level (p

Alika [10]

Answer: The critical value for a two-tailed t-test = 2.056

The critical value for a one-tailed t-test = 1.706

Step-by-step explanation:

Given : Degree of freedom : df= 26

Significance level : $\alpha=0.05$

Using student's t distribution table , the critical value for a two-tailed t-test will be :-

$t_{\alpha/2, df}=t_{0.025,26}=2.056$

The critical value for a two-tailed t-test = 2.056

Again, Using student's t distribution table , the critical value for a one-tailed t-test will be :-

$t_{\alpha, df}=t_{0.05,26}=1.706$

The critical value for a one-tailed t-test = 1.706
