Answer:

2x + 1

Step-by-step explanation:

Answer:

The expression simplifies to [tex]2x+1[/tex]

Step-by-step explanation:

To divide the polynomials, we must first factor the trinomial into binomials so we can easily divide it by the binomial.  Factoring [tex]2x^2-5x-3[/tex] results in the expression [tex](x-3)(2x+1)[/tex].  Since these two values are multiplied, the [tex](x-3)[/tex] can be canceled out by the divisor, which is the exact same expression.  This leaves us with our final answer: [tex]2x+1[/tex].

Answer:

hi its just like the dood above me said *dude sorry if i was late

Step-by-step explanation:

Using shifting concepts, it is found that function g is given by:

[tex]g(x) = \frac{x^2 - 4x - 12}{4}[/tex]

--------------

--------------

The parent function is:

[tex]f(x) = x^2[/tex]

--------------

Horizontally stretching by a factor of 2.

[tex]f(\frac{x}{2}) = (\frac{x}{2})^2 = \frac{x^2}{4}[/tex]

--------------

Shifting left 2 units:

[tex]f(\frac{(x-2)}{2}) = \frac{(x - 2)^2}{4} = \frac{x^2 - 4x + 4}{4}[/tex]

--------------

Shifting down 4 units:

[tex]g(x) = f(\frac{(x-2)}{2}) - 4 = \frac{x^2 - 4x + 4}{4} - 4 = \frac{x^2 - 4x + 4}{4} - \frac{16}{4} = \frac{x^2 - 4x - 12}{4}[/tex]

Complete Question

The complete question is shown on the first uploaded image

Answer:

What is the mean of the four sample means is  [tex]\= x  =  6.125 [/tex]

What is the mean of the four sample variances is   [tex]\= x_v  =  3.71[/tex]

A sample statistic is an unbiased  point estimator  if the average value of the sample statistic, obtained over all possible samples, is equal to the population parameter.

A sample statistic is biased if it consistently underestimates or overestimates the corresponding population parameter.

A sample mean (that is, M = sigma X/n) is unbiased estimator of the population mean

A sample variance that is computed as s^2 = SS/(n - 1) is unbiased estimator of the population variance.

Step-by-step explanation:

From the question we are told that

   Mean    6.00   6.75    6.50    5.25    6.00

   Variance    5.50    2.25    1.67   6.25  4.67

Generally the mean of the four sample means is mathematically represented as

      [tex]\= x  =  \frac{6.00+   6.75 +   6.50  +  5.25  +  6.00}{4}[/tex]

=>  [tex]\= x  =  6.125 [/tex]

Generally the mean of the four sample variances is mathematically represented as

      [tex]\= x_v  =  \frac{5.50+ 2.25+ 1.67+ 6.25 +4.67}{4}[/tex]

=>    [tex]\= x_v  =  3.71[/tex]

Answer:

The proportion of the population believes that passwords should be replaced with biometric security is not more than 50%.

Step-by-step explanation:

In this case we need to test the claim that more than half of the population believes that passwords should be replaced with biometric security.

Assume that the significance level of the test is, α = 0.05.

The hypothesis can be defined as follows:  

H₀: The proportion of the population believes that passwords should be replaced with biometric security is 50%, i.e. p = 0.50.  

Hₐ: The proportion of the population believes that passwords should be replaced with biometric security is more than 50%, i.e. p > 0.50.  

The information provided is:

[tex]n = 510\\\hat p=0.53[/tex]

Compute the test statistic value as follows:

 [tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

    [tex]=\frac{0.53-0.50}{\sqrt{\frac{0.50(1-0.50)}{510}}}\\\\=1.354991\\\\\approx 1.35[/tex]

The test statistic value is 1.35.

The decision rule is:

The null hypothesis will be rejected if the p-value of the test is less than the significance level.

Compute the p-value as follows:

 [tex]p-value=P(Z>1.35)[/tex]

                 [tex]=1-P(Z<1.35)\\=1-0.91149\\=0.08851\\\approx0.088[/tex]

p-value = 0.088 > α = 0.05.

The null hypothesis will not be rejected at 5% significance level.

Thus, there is not enough evidence to support the claim.

Conclusion:

The proportion of the population believes that passwords should be replaced with biometric security is not more than 50%.

Answer:

The second one for both a and b.

Step-by-step explanation:

The first cereal box is:

8•3•11=264 inches cubed

the second cereal box is:

10•10•3=300 inches cubed

a. The box that holds more cereal would be the second one, since it has more volume.

b. The box that requires more material to make is the second one, since the it is bigger in volume, therefore, bigger in length and width.

Answer: A. Yes, the proportion of sampled angles smaller than 15° is greater than 0.50.

Step-by-step explanation:

Given the data :

Class: _______ relative frequency

0−<5 __________ 0.179

5−<10 __________ 0.168

10−<15 _________ 0.174

15−<20 _________ 0.135

20−<30 _________0.193

30−<40 _________ 0.071

40−<60 _________ 0.051

60−<90 _________ 0.029

Evaluating the proportion of sampled angles less than 15°. This consist of the following classes :

Class: ________frequency

0−<5 __________ 0.179

5−<10 __________ 0.168

10−<15 _________ 0.174

Summing up the relative frequency values :

(0.179 + 0.168 + 0.174) = 0.521

0.521 * 100% = 52.1%

Hence, more than 50% of the sampled angles are smaller than 15°
