shutvik [7]3 years ago

Step-by-step explanation:

The quadratic equation given to us is ,

→ 4v² + 6v - 88 = 0 .

So , wrt to standard form of a quadratic equation ax² + bx + c = 0 , the Zeroes are given by using the Quadratic formula as ,

⇒ x = -b ± √ ( b² - 4ac) / 2a

⇒ x = -6 ± √ [6² - 4 × 4 × (-88) ] / 2×4

⇒ x = -6 ± √ [ 36 + 1408 ] / 8

⇒ x = -6 ± √ 1444 / 8

⇒ x = -6 ± 38 / 8

⇒ x = -6 +38/ 8 , -6 -38 / 8

⇒ x = 32/8 , -44/8

⇒ x = 4 , -11/2

Here I took v as x . So we can replace it .

<h3><u>Hence </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>v</u><u> </u><u>is</u><u> </u><u>4</u><u> </u><u>,</u><u> </u><u>-</u><u>1</u><u>1</u><u>/</u><u>2</u><u> </u><u>.</u></h3>

Ardem collected data from a class survey. He then randomly selected samples of five responses to generate four samples.
scoundrel [369]

Solution: The sample mean of sample 1 is:

\bar{x}=\frac{4+5+2+4+3}{5}= \frac{18}{5}=3.6

The sample mean of sample 2 is:

\bar{x}=\frac{2+2+6+5+7}{5}= \frac{22}{5}=4.4

The sample mean of sample 3 is:

\bar{x}=\frac{4+6+3+4+1}{5}= \frac{18}{5}=3.6

The sample mean of sample 4 is:

\bar{x}=\frac{5+2+4+3+6}{5}= \frac{20}{5}=4

The minimum sample mean of the four sample means is 3.6 and maximum sample mean of the four sample means is 4.4.

Therefore, using  his four samples, between 3.6 and 4.4 will Ardem's actual population mean lie.

Hence the option 3.6 and 4.4 is correct

The length of a rectangle is 5 centimeters less than twice it’s width. The perimeter of the rectangle is 80 cm. What are the dim
algol [13]
<h3><u>The length is equal to 25.</u></h3><h3><u>The width is equal to 15.</u></h3>

l = 2w - 5

2l + 2w = 80

We have a value for l, so we can plug it into the second equation to solve for w.

2(2w - 5) + 2w = 80

Distributive property.

4w - 10 + 2w = 80

Combine like terms.

6w - 10 = 80

Add 10 to both sides.

6w = 90

Divide both sides by 6.

w = 15

Now that we have a value for w, we can plug it into the original equation to solve for l.

l = 2(15) - 5

l = 30 - 5

l = 25
