Rewrite the quadratic function below in Standard Form.
y = (x - 4) (x + 3)

Answers

the standard form of a quadratic formula is

y = ax^2 + bx + c

in this case you will solve using foil method

(× - 4)(x + 3)

(x × x) +( x × 3 )(- 4 × x) ( -4)× 3))

x^2 + 3x - 4x -12

x^2 - x - 12

therefore

y = x^2- x - 12

find the slope, and in y=mx+b form

Answers

Answer:

slope: 1y = x +6

Step-by-step explanation:

The slope can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

Using the first two table entries, this is ...

m = (5 -4)/(-1 -(-2)) = 1/1

m = 1

The y-intercept can be found using the formula ...

b = y1 -m·x1

b = 4 -(1)(-2) = 6

Then the slope-intercept equation is ...

y = mx + b

y = x + 6

The slope is 1; the equation is y = x+6.

Answer:

the answer is

slope:1

y=x+6

Assume that the probability of a defective computer component is 0.02. Components arerandomly selected. Find the probability that the first defect is caused by the seventh componenttested. Find the expected number and variance of the number of components tested before adefective component is found.

Answers

Answer:

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.

Step-by-step explanation:

Assume that the probability of a defective computer component is 0.02. Components are randomly selected. Find the probability that the first defect is caused by the seventh component tested.

First six not defective, each with 0.98 probability.

7th defective, with 0.02 probability. So

[tex]p = (0.98)^6*0.02 = 0.0177[/tex]

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.

Find the expected number and variance of the number of components tested before a defective component is found.

Inverse binomial distribution, with [tex]p = 0.02[/tex]

Expected number before 1 defective(n = 1). So

[tex]E = \frac{n}{p} = \frac{1}{0.02} = 50[/tex]

Variance is:

[tex]V = \frac{np}{(1-p)^2} = \frac{0.02}{(1-0.02)^2} = 0.0208[/tex]

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.

Answer:

The solution to these question can be defined as follows:

Step-by-step explanation:

[tex]H_0: \mu = 33 \ versus\\\\ H_a: \mu > 33\\\\\bar{X} = 33.11\\\\S = 4.7468\\\\n = 47\\\\df = n - 1 = 46\\\\\alpha = 0.05\\\\[/tex]

Testing statistic:

[tex]t = \frac{(\bar{X} - \mu)}{[\frac{S}{\sqrt{(n)}}]}[/tex]

[tex]= \frac{(33.11 – 33)}{\frac{4.7468}{\sqrt{47}}}\\\\= \frac{0.11}{0.6924}\\\\= 0.1589\\\\P-value = 0.4372\\\\P-value > \alpha = 0.05[/tex]

Therefore the null hypothesis we do not deny, it is not clear enough so that the median age once British men get engaged is higher than in 2013.

A 2-kilogram bag of potting soil costs $1.96. What is the unit price?

Answers

Answer:

The unit price is $0.98

Answer:

98¢

Step-by-step explanation:

The unit price of an item is the price of one unit. In this case, this would be the price of a single kilogram.

To find the unit price, we'll divide the given price by the amount of units it is for. So, divide 1.96 by 2.

1.96 ÷ 2 = unit price

0.98 = unit price

This means the price of a single kilo of potting soil is $0.98. The unit price of the potting soil is 98 cents.

Good luck :)

f(x) = 3 + 6x

Find the inverse of f(x):

x = 3 + 6f⁻¹(x)6f⁻¹(x) = x - 3f⁻¹(x) = (x - 3) / 6

f · f⁻¹( ∛5/6) = f( f⁻¹( ∛5/6)) = f((∛5/6 - 3)/6) = 3 + 6((∛5/6 - 3)/6) =3 + ∛5/6 - 3 =∛5/6

f · f⁻¹(x) = f(f⁻¹(x)) = f((x - 3)/6) = 3 + 6(x - 3)/6 = 3 + x - 3 = x

First find the with of the triangle,by measureing the points with the base.

Second to find the base simply look equilateral and the half circle. and see how the lines in between it and the triangle collide. and count the spaces to find the base.

Third measure the height with the best estimate.

And finally, multiply by (h×w) and divide by the base.

Answer:

42,84

Step-by-step explanation:

Remark

Two of the sides are 12 inches. The third side is also 12 but it serves as a diameter of the semicircle.

The circumference of the semi circle is 2*pi*r /2 = pi * r

The total perimeter is pi * r + 2*12

r = d/2

r = 12/2

r = 6

Perimeter = 6*pi + 24 might be you answer.

Perimeter = 42.84

I don't know which answer to use. It all depends how other questions have been answered. Sometimes you take the decimal answer and sometimes you take the answer in terms of pi. I think the latter is what I would try first.

PLEASE HELP ASAPPPPP Find the value of x for mAB= 27° and mCD= 49°. The figure is not drawn to scale

Answers

Answer:

Step-by-step explanation:

The other guy has mislead other people. If i turned my thing in, I would have gotten a 90% instead of 100%.

It is A.

38 degrees.

The measure of x is (a) 38 degrees

The given parameters are:

[tex]mAB = 27^o[/tex]

[tex]mCD = 49^o[/tex]

The measure of x, is the average of angles AB and CD.

So, we have:

[tex]x = \frac{mAB + mCD}{2}[/tex]

Substitute known values of AB and CD in the above equation.

So, we have:

[tex]x = \frac{27^o + 49^o}{2}[/tex]

Add 27and 49

[tex]x = \frac{76^o}{2}[/tex]

Divide 76 by 2

[tex]x = 38^o[/tex]

Hence, the measure of x is (a) 38 degrees
