Given:

The quadratic equation is :

[tex]16x^2-20x-6=0[/tex]

To find:

The quadratic formula for the given equation after substituting the values.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]16x^2-20x-6=0[/tex]

In this equation, [tex]a=16,b=-20,c=-6[/tex].

Substituting [tex]a=16,b=-20,c=-6[/tex] in the above formula, we get

[tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex]

Therefore, the required quadratic formula for the given equation after substituting the values is [tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex].

Each salad contains red beans, Lima beans, and black eyed beans. Use the information below to determine how many of each of the three types of beans are needed

Answers

Answer:

A.) Black eyed beans = at least 3 ; Red beans = atleast 4 ; Lima beans = atleast 5

B.) Red and Lima beans = 5 each ; Black eyed beans = 8

C.) Lima beans = 4 ; Black eyed beans = 2 ; Red beans = 2

Step-by-step explanation:

Let :

Black eyed beans = x

Red beans = x + 1

Lima beans = x + 1 +1 = x + 2

Total beans is atleast 12

x + (x +1) + (x + 2) ≥ 12

x + x + 1 + x + 2 ≥ 12

3x + 3 ≥ 12

3x ≥ 9

x ≥ 3

Black eyed beans = at least 3

Red beans = atleast 4

Lima beans = atleast 5

B.)

Same number of Red and Lima beans

Black eyed beans is 3 more than red beans

Total beans = 18

Red and Lima = x + x

Black eyed beans = x + 3

x + x + x + 3 = 18

3x + 3 = 18

3x = 18 - 3

3x = 15

x = 5

Red and Lima beans = 5 each

Black eyed beans = 3 + 5 = 8

C.)

Total beans in salad = x

Number of red beans = 2

Lima beans = 2 * 2 = 4

Lima beans = 1/2 of x ; x/2

4 = x /2

8 = x = total beans in salad

Red + lima + black eyed = 8

2 + 4 + black-eyed = 8

Black eyed beans = 8 - 6 = 2

Lima beans = 4

Black eyed beans = 2

Red beans = 2

The length of the side DE is approximately 541.3 feet long.

There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{x} =\frac{sin(10^{o})}{94}[/tex] ⇒ [tex]\frac{x}{sin(90^{o})} =\frac{94}{sin(10^{o})}[/tex] ⇒ [tex]x = \frac{94*sin(90^{o})}{sin(10^o)}[/tex] ⇒ [tex]x=541.3ft.[/tex]

lines p and q line in the coordinate plane. An equation for line p is y=0.36x-600. The slope of line q is 0.2 less than the slope of line p. what is the slope of line q?

Answers

Answer:

y = -1/3x -3

Step-by-step explanation:

Lines

Perpendicular lines have negative reciprocal slopes. To find the line, convert the slope of q and substitute it with (6, -5) into point-slope form.

y = 3x + 5 is q. It has a slope of 3. So, p will have a slope of -1/3.

y - y1 = m ( x - x1)

y - (-5) = -1/3 ( x - 6)

y + 5 = - 1/3x + 2

y = -1/3x - 3

1, p = -0.5

Step-by-step explanation:

2(p+5) = 4 - 10p

2p+10 = 4 - 10p

2p + 10p = 4 - 10

12p = -6

p = -6/12

It is said that happy and healthy workers are efficient and productive. A company that manufactures exercising machines wanted to know the percentage of large companies that provide on-site health club facilities. A sample of 240 such companies showed that 99 of them provide such facilities on site.

Construct a 98% confidence interval for the percentage of all such companies that provide such facilities on site. What is the margin of error for this estimate?

Answers

Answer:

Confidence interval is 0.7 ≤ p ≤ 0.8

The margin of error is 7.1 %

Step-by-step explanation:

We have to calculate a 98% confidence interval for the proportion.

The sample proportion is p=0.75.

The standard error of the proportion is:

Here we have, the proportion or point estimate given by

= 150/200 = 0.75

Sample size, n = 200

The formula for confidence interval, CI, given a proportion, is;

At 98% z = ±2.326348

Plugging in the values of, , z and n we get;

CI = 0.6787704 ≤ p ≤ 0.8212296

To one decimal place, we have

CI = 0.7 ≤ p ≤ 0.8
