A sewing club used 48 feet of fabric to make 8 blankets. At this rate how many blankets can be made from 12 feet of fabric?

vlada-n [284]

If 48 = 8 than 12 = x

to find x divide 48 by 8 which is 6. every 6 feet of fabric 1 blanket is made

so 12/6 equals 2

2 blankets can be made from 12 feet of fabric

Resolve 3x-1÷(x+1)^2 into partial fraction<br>

garri49 [273]

9514 1404 393

Answer:

3/(x +1) -4/(x +1)^2

Step-by-step explanation:

The partial fraction expansion will be of the form ...

A/(x+1)^2 +B/(x+1)

We can find the values of A and B by writing the sum of these terms:

= (A +B(x +1))/(x +1)^2

Then we require ...

B = 3

A +B = -1 ⇒ A = -4

So, the desired expansion is ...

3/(x +1) -4/(x +1)^2

A population contains six members, with values 1,1,2,3,5,10. A random sample of size 3 is drawn without replacement. Estimate th

Ronch [10]

Answer:

So, the population mean is 3.66.

Step-by-step explanation:

We will calculate the average value by summing all the values and dividing by the size of sample.

We have population contains six members, with values 1,1,2,3,5,10.

Therefore, n=6.

We use the formula to calculate the population mean:

$\mu=\frac{x_1+...+x_n}{n}\\\\\mu=\frac{1+1+2+3+5+10}{6}\\\\\mu=\frac{22}{6}\\\\\mu=3.66$

So, the population mean is 3.66.

P=$4000.00,A=$5300.00,t=5 years

Answer:

The rate of Simple Interest is 6.5 %

Step-by-step explanation:

Given as :

Principal = $ 4000.00

Amount = $ 5300.00

The time period of loan = 5 years

Let The rate of simple interest = R

Now,

From Simple Interest method

Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

And , Simple Interest = Amount - Principal

So , Simple Interest = $ 5300.00 - $ 4000.00

Or, Simple Interest = $ 1300

Now, Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

So, $ 1300 = $\frac{ 4000\times Rate\times 5}{100}$

Or, $ 1300 × 100 = $ 4000 × Rate × 5

Or, Rate = $\frac{1300\times 100}{4000\times 5}$

Or, Rate = 6.5

Hence The rate of Simple Interest is 6.5 % Answer
