Answer:

Her premium is $1058.50.

Step-by-step explanation:

Emily Webster purchased a 20 year endowment policy at age 27 with a face value of $25,000.

As per the table, we are clear that, we have to find Emily's annual premium.

Emily is 27 but we will take 24 (as given in table note number 4)

A 24 year old's rate is 42.34.

Table gives per $1000 face value.

In case of Emily, it is \frac{25000}{1000}=25

So, we get the premium now as : 25\times42.34=1058.50 dollars

Therefore, Emily's premium is $1058.50.

Use linear regression to find the equation for the linear function that best fits this data. Round both numbers to two decimal p
natta225 [31]

Answer:

The equation of the linear function that best fits the data is,

<em>y</em> = 18.66<em>x</em> + 66.87.

Step-by-step explanation:

The line of best is of the form: <em>y</em> = <em>mx</em> + <em>b</em>.

Here, <em>m</em> = slope of the line and <em>b</em> = intercept.

The formula to compute the intercept and slope are:

b=\frac{\sum Y.\sum X^{2}-\sum X.\sum XY}{n.\sum X^{2}-(\sum X)^{2}}

m=\frac{n.\sum XY-\sum X.\sum Y}{n.\sum X^{2}-(\sum X)^{2}}

Consider the table below for the values of <em>∑ X, ∑ Y, ∑ X² </em>and <em>∑ XY</em>.

Compute the value of  intercept and slope as follows:

b=\frac{\sum Y.\sum X^{2}-\sum X.\sum XY}{n.\sum X^{2}-(\sum X)^{2}}=\frac{(793\times91)-(21\times3102)}{(6\times91)-(21)^{2}} =66.867

m=\frac{n.\sum XY-\sum X.\sum Y}{n.\sum X^{2}-(\sum X)^{2}}=\frac{(6\times3102)-(21\times793)}{(6\times91)- (21)^{2}} =18.657

The line of best fit is:

y=mx+b\\y=18.657x+66.867\\y=18.66x+66.87

Thus, the equation of the linear function that best fits the data is <em>y</em> = 18.66<em>x</em> + 66.87.

Dmitrij [34]

Answer:

0.4\%

Step-by-step explanation:

Given: 60% of the boys play baseball and 24% of the boys play baseball and football in Seaton Park School

To find: percentage of those that play baseball also play football

Solution:

Let B denotes boys who play baseball and F denotes boys who play football.

P(B)=60\%

P(F\cap B)=24\%

Percentage of those that play baseball also play football = P\left ( F|B \right )=\frac{P(F\cap B)}{P(B)}=\frac{24}{60}=\frac{2}{5}=0.4\%

A rectangle has a perimeter of 144 inches. The width of the rectangle is 12 inches less than the length. What is the width, in i
mrs_skeptik [129]

The width in inches would be 12, because of the formula:

length x width = perimeter

so you would do it reverse!

perimeter/length = width

so, 144/12 = 12
