A student borrows $12,000 at a simple interest rate of 4.5% for 5 years. How much interest is ones at the end of 5 years, and wh

Step2247 [10]

Answer:

$12,000(1+\frac{4.5}{100}*5)=12,000(1.225)=\$14,700$

Step-by-step explanation:

Simple interest is where interest is only accumulated on the principle, so at 4.5% for 5 years, 22.5% is added to the principal.

For a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears. Minitab was us

Yakvenalex [24]

Answer:

There is a linear correlation between the chest size and weight

Proportion of the variation in weight can be explained by the linear relationship between weight and chest size is 0.006724 .

Step-by-step explanation:

Null Hypothesis: $H_0$ = There is no linear correlation between the chest size and weight

Alternative Hypothesis : $H_a$ =There is a linear correlation between the chest size and weight

The value of the linear correlation coefficient is r=0.882.

n = 8

Formula : $t=\frac{r\sqrt{n-2}}{\sqrt{1-r^2}}$

$t=\frac{0.882\sqrt{8-2}}{\sqrt{1-(0.882)^2}}$

$t=4.584$

Degree of freedom = n-1 = 8-1 = 7

α =0.05

so, p value is 2.365

t calculated > t critical

So, we reject the null hypothesis

So, There is a linear correlation between the chest size and weight

The proportion of the variation in weight can be explained by the linear relationship between weight and chest size = $r^2 = (0.082)^2=0.006724$

Hence proportion of the variation in weight can be explained by the linear relationship between weight and chest size is 0.006724 and There is a linear correlation between the chest size and weight

One method of trying to find the area of a polygon is to decompose the polygon

lilavasa [31]

Answer: True

You can break the polygon up into smaller pieces such as triangles. Find the area of each triangle, and then add up those smaller areas to get the overall total area.
