Step-by-step explanation:

According to an algebra calculator, there is no way to evaluate it because there is no variable. Hopefully this helps?

HURRRY TIME LIMIT!!!!!!!!!

Answer:

No, because each sample of 100 does not have the same chance of being selected.

Step-by-step explanation:

Simple random samples require that every possible sample of the population has an equal chance of being selected. Because of the fact that certain ages are being picked at certain amounts, not every possible sample has the same chance of being selected, so this is not an SRS.

Answer:

$a_3=22$

Step-by-step explanation:

Given that,

a₁ = 10

$a_n=a_{n-1}+6$

We can find second term first.

$a_2=a_{2-1}+6\\\\=a_1+6\\\\=10+6\ (Given\ a_1=10)\\\\=16$

We need to find the third term of the above sequence. Put n = 3 in the above sequence as follows :

$a_3=a_{3-1}+6\\\\=a_2+6$

Put a₂ = 16

$a_3=16+6\\\\=22$

Hence, the third term of the sequence is 22.

how much difference is there between investing $5,000 at 4% simple interest for 5 years and investing that same amount at 4% com

miskamm [114]

To find the difference between the tow investments we are going to use tow formulas. Simple interest formula for our simple interest investment, and compound interest formula for our compound interest investment.
- Simple interest formula: $A=P(1+rt)$
where
   $A$ is the final investment value
   $P$ is the initial investment
   $r$ is the interest rate in decimal form
   $t$ is the time in years
For our problem we know that $P=5000$ , $r= \frac{4}{100} =0.04$ , and $t=5$ , so lets replace those values in our simple interest formula to find $A$ :
$A=5000(1+(0.04)(5))$
$A=5000(1.2)$
$A=6000$

Now that we know the final investment value of our simple interest investment, lets use the compound interest formula to find the final investment value of the other one:
- Compound interest formula: $A=P(1+ \frac{r}{n})^{nt}$
where
   $A$ is the final investment value
   $P$ is the initial investment
   $r$ is the interest rate in decimal form
   $n$ is the number of times the interest is compounded per year
   $t$ is the time in years
For our problem we know that $P=5000$ , $r= \frac{4}{100} =0.04$ , and $t=5$ . Since we know that the interest is compounded quarterly (each 4 months), it mean that is compounded $\frac{12months}{4months} =3$ times per year, so $n=3$ . Now that we have all the vales, lets replace them in our formula:
$A=5000(1+ \frac{0.04}{3} )^{(3)(5)}$
$A=5000(1+ \frac{0.04}{3} )^{15}$
$A=6098.95$

now that we know the final amounts of our investments, lets find how much difference is between them:
$6098.95-6000=98.95$

We can conclude that the difference between invest $5000 in a compound interest investment vs a simple interest investment is $98.95.

What is the slope of 3x+8y-1=0

Fudgin [204]

One of the most common ways to find the slope is to put the problem in standard, slope-intercept form, which is y=mx+b. The easiest way to describe this process is to isolate y.
Here's how you do it for this problem:
$3x+8y-1=0 \\ (3x+8y-1)+1=(0)+1 \\ 3x+8y=1 \\ (3x+8y)-3x=(1)-3x \\ 8y=-3x+1 \\ (8y)/8=(-3x)/8+(1)/8 \\ y= -\frac{3}{8}x+ \frac{1}{8}$
Since m is your slope, the answer would be -3/8.
Hope this helps!
