It's false - when you plug in a variable for x, the products are not equal.

The answer will be false, because the value of x is always 1 unless told otherwise. So if you do the math the sums are different thus your answer is false. :)

Which graph shows data whose r-value is most likely closest to 0?

Alexxandr [17]

Answer:

D) A graph shows both axes unnumbered. Points are scattered all over the graph.

Step-by-step explanation:

The value of "r" tells you how strong the correlation is between the independent and dependent variables. If its close to 0, then there will be hardly any correlation, so a good example of this is the 4th option where there's no pattern in the data set.

THIS IS 8TH GRADE MATH (Pre-Algebra).

gtnhenbr [62]

First you need to set up a formula. Underline all of your givens:

<u>Spent 1/2 on clothes
$6 more for washing windows
Ended with $10.
</u>
now you need to set up an equation.
<u>
</u>You know she ended up with $10. So that will be what it equals. Then you know that she earned $6 in addition to her allowance. So this would be (x= allowance) (x+6)/2 = 10.
<u>
</u>Now you need to solve for x.
Multiply both sides by 2.
<u>
</u>x+6=20<u>
</u>Now subtract both sides by 6 to get x alone:
<u>
</u>x=$14<u>
</u><u>

1.Jessica lost some of her money. She found 3/6 of it. What fraction of her money is still missing ?

notsponge [240]

Hey there!

1.
If Jessica found 3/6 of her money, half of it is still missing.

This is because 3/6 = 1/2, so Jessica also found half of her money and is missing half of it.

2.

16 ounces = 1 pound

16 ounces * 10 pounds = 160 <------

If the baby weighs 10 pounds, he weighs 160 ounces.

Hope this helps you.
Have a great day!

What is the sum of the infinite geometric series? Sigma-Summation Underscript n = 1 Overscript 4 EndScripts (negative 144) (one-

Irina18 [472]

The sum of the infinite geometric series is -288.

<h2>Given that</h2>

A finite geometric series with n = 4, a₁ = -144, and r = ½.

<h3>We have to determine</h3>

What is the sum of the infinite geometric series?

<h3>According to the question</h3>

The sum of the infinite is determined by the following formula;

$\rm S\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\$

A finite geometric series with n = 4, a₁ = -144, and r = ½.

Substitute all the values in the formula;

$\rm S\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\S\infty = \dfrac{-144 (1- \dfrac{1}{2}^4)}{1-\dfrac{1}{2}}\\\\S \infty = \dfrac{-144 \times \dfrac{15}{16}}{\dfrac{1}{2}}\\\\S \infty = -270$

Therefore,

The sum of the infinite geometric series is,

$\rm S = \dfrac{a_1}{1-r}\\\\S=\dfrac{-144}{1-\dfrac{1}{2}}\\\\S = \dfrac{-144}{0.5}\\\\S = -288$

Hence, the sum of the infinite geometric series is -288.
