Answer: p > -18

Step-by-step explanation:

-2/3p - 4 < 8

3 * (-2/3p - 4 < 8) * 3

-2p - 12 < 24

-2p < 24 + 12

-2p < 36

Divide both sides of the inequality by -2 and flip the sign

-2p/-2 < 36/-2

p > -18

Alexus [3.1K]

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, <em>α</em> = 0.05.

The hypothesis can be defined as follows:  

<em>H</em>₀: The proportion of the population believes that passwords should be replaced with biometric security is 50%, i.e. <em>p</em> = 0.50.  

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

The information provided is:

n = 510\\\hat p=0.53

Compute the test statistic value as follows:

 z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}

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

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:

 p-value=P(Z>1.35)

                 =1-P(Z

<em>p</em>-value = 0.088 > <em>α</em> = 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%.

Hey cutie pls help!!

1. m angle 2 = 122

m angle 2 is congruent to m angle 4

2. m angle 1 = 58

m angle 1 is supplementary to m angle 2, so their sum is 180. Thus, m angle 1 + 122 = 180, so m angle 1 = 180 -122 = 58.

If you appreciated my explanation, a brainliest award would be most appreciated.

rectangle q has an area of 2 square units thea drew scaled version and labled it rectangle r what scale factor did thea use to g
alexgriva [62]

Answer:

<em>It has been given that Rectangle Q has an area of 2 square units.</em>

<em>Thea Drew a scaled version of Rectangle Q and marked it as R.</em>

<em>As you must keep in mind If we draw scaled copy of pre-image, then the two images i.e Pre-image and Image are similar.</em>

<em>As you have not written what is the scale factor of transformation</em>

<em>Suppose , Let the Scale factor of transformation= k</em>

<em>Rectangle Q = Pre -image, Rectangle R= Image</em>

<em>If, Pre-Image < Image , then scale factor is k >1.</em>

<em>But If, Pre-Image > Image , then Scale factor will be i.e lies between, 0<k<1.</em>

jolli1 [7]

Answer:

9 minutes

Step-by-step explanation:

First, you will want to add up all the time spent per problem.

3(9.5)+2(8.25)=45

Then, divide 9 from 45. 45÷5=9.

Therefore, she would have spent 9 minutes per problem.

If (x+1,10)=(4,2y) then find the value of x &amp; y
lawyer [7]

Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>3</u></em><em><u> </u></em><em><u> </u></em><em><u>&</u></em><em><u> </u></em><em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>5</u></em></h2>

Step-by-step explanation:

<h3><em><u>Given</u></em><em><u>, </u></em></h3>

(x+1, 10) = (4, 2y)

<u>First</u><u> </u><u>x</u><u> </u><u>coordinate</u><u>, </u>

x + 1 = 4

=> x = 4 - 1

=> <em>x = 3 (Ans) (i)</em>

<u>Second</u><u> </u><u>y</u><u> </u><u>coordinate</u><u>, </u>

10 = 2y

=  > y =  \frac{10}{2}

=> <em>y</em><em> </em><em>=</em><em> </em><em>5</em><em> </em><em>(</em><em>Ans</em><em>)</em><em> </em><em>(</em><em>ii</em><em>)</em>
