Use the quadratic formula to find the solutions to the
nadezda [96]

Answer:

D

Step-by-step explanation:

The quadratic formula:

\frac{-b\pm \sqrt{b^2-4ac}}{2a}

where a is the coefficient of x^2, b being the coefficient of x and c being the constant.

Plug in the values:

\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\cdot \:5}}{2\cdot \:2}

\frac{5\pm\sqrt{-15} }{4}

Since \sqrt{-15} =\sqrt{-1} \sqrt{15} =i \sqrt{15}

The answer is:

\frac{5\pm i \sqrt{15} }{4}

In a random sample of 500 handwritten zip code digits, 464 were read correctly by an optical character recognition (OCR) system
In-s [12.5K]

Answer:

z= 2.38

P = 0.008656

Step-by-step explanation:

Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072

We formulate our null and alternate hypothesis as

H0 =  0.9 ;       H0 > 0.9

The degree of confidence = 90%

z₀.₀₅ = 1.645 for  α= 0.05

We use the test statistic

z=  x- np/√npq

z= 466-500 *0.9/ √500 * 0.9(1-0.9)

z= 466- 450/ √45

z= 16/6.7082

z= 2.38

As the calculated value of z= 2.38  is greater than α =1.645 so we reject H0.

If H0 is true the P value is calculated as

P = 1- Ф( 2.38)

P = 1-0.991344=0.008656

miley has d decks of playing cards. write an equation for a function that shows how many c cards miley has all together if each
anastassius [24]
Answer is C= 52d
To solve problems like this, you would just need to think about what the question is asking you one step at a time
List what you know
- There are 52  cards in each deck
- We need how many cards in total

So let us think about it from a mathematical standpoint
1 deck= 52 cards         1 x 52= 52
that means.....
2 deck= 104 cards      2 x 52 = 104
3 deck= 158 cards      3 x 52 = 158
and the list keeps going
That means that 52 multiplied by whatever number d is will get you the total number of cards.
thus C= 52d
