Answer:

<em> f ( x ) = - 2x^2 + 3x + 1</em>

Step-by-step explanation:

If f (x ) extends to → − ∞, as x→ − ∞ , provided f(x) → − ∞, as x → +∞, we can rewrite this representation as such;

− ∞  < x < ∞, while y > − ∞

Now the simplest representation of this parabola is f ( x ) = - x^2, provided it is a down - facing parabola;

If we are considering a down - facing parabola, the degree of this trinomial we should create should be even, the LCM being negative. Knowing that we can consider this equation;

<em>Solution; f ( x ) = - 2x^2 + 3x + 1</em>, where the degree is 2, the LCM ⇒ - 2

A seamstress needs to cut 15 inches pieces of ribbon from a roll of ribbon that is 9 feet in length what is the greatest number
Natali [406]

Answer: 36

Step-by-step explanation:

One roll is of length = 9 feet

1 foot = 12 inches

9 feet = 12 *9 = 108 inches

Since there are 5 rolls

So, total length of 5 rolls = 108 * 5 = 540 inches

Since we are given that A seamstress needs to cut 15-inch pieces of ribbon from a roll of ribbon that is 9 feet in length.

We are supposed to find . What is the greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon

So, number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon:

Hence the greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon is 36

In the Country A legal system, a defendant is presumed innocent until proven guilty. Consider a nullhypothesis, H0, that the def
Pie

Using error concepts, it is found that in this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

<h3>What are Type I and Type II errors?</h3>
  • Type I: Rejection of a true null hypothesis. The null hypothesis is true, but from a sample, you get enough evidence to reject.
  • Type II: Non-rejection of a false null hypothesis. The null hypothesis is false, but from a sample, you do not get enough evidence to reject.

Hence:

In this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

Phantasy [73]

Answer:

\hat p \pm Z*\sqrt{\frac{\hat p\times(1-\hat p)}{n} }

=0.5546\pm1.96*\sqrt{\frac{0.5546\times(1-0.5546)}{458} }

=0.5546\pm1.96*\sqrt{\frac{0.5546\times(0.4454)}{458} }

=0.5546\pm1.96*\sqrt{\frac{0.2470}{458} }

=0.5546\pm1.96*\sqrt{0.00053934}

=(0.5091,0.6001)

Lower limit for confidence interval=0.5091

             

Upper limit for confidence interval=0.6001

Step-by-step explanation:

We have given,              

             

x=254          

n=458          

Estimate for sample proportion= \bar p = 0.5546

Level of significance is =1-0.95=0.05      

Z critical value(using Z table)=1.96      

Confidence interval formula is

\hat p \pm Z*\sqrt{\frac{\hat p\times(1-\hat p)}{n} }

=0.5546\pm1.96*\sqrt{\frac{0.5546\times(1-0.5546)}{458} }

=0.5546\pm1.96*\sqrt{\frac{0.5546\times(0.4454)}{458} }

=0.5546\pm1.96*\sqrt{\frac{0.2470}{458} }

=0.5546\pm1.96*\sqrt{0.00053934}

=(0.5091,0.6001)

Lower limit for confidence interval=0.5091

             

Upper limit for confidence interval=0.6001
