Answer:

The test statistic  Z = 2 < 2.576 at 0.10 level of significance

Null hypothesis is accepted

Step-by-step explanation:

Step(i):-

Given Population proportion P = 0.49

                                Q = 1 - P = 1 - 0.49 = 0.51

Given sample proportion

                            [tex]p^{-} = \frac{x}{n} = \frac{154}{281} = 0.548[/tex]

Level of significance = 0.10

Null hypothesis : H₀ : P = 0.49

Alternative Hypothesis :H₁: P≠ 0.49

Step(ii):-

Test statistic

                 [tex]Z = \frac{p^{-} -P}{\sqrt{\frac{PQ}{n} } }[/tex]

                [tex]Z = \frac{0.548-0.49}{\sqrt{\frac{0.49 X 0.51}{281} } }[/tex]

                Z = 2

The tabulated value = 2.576

The calculated value Z = 2 < 2.576 at 0.10 level of significance

Null hypothesis is accepted

Answer:

Her final exam grade would be 11.7521 above the mean

Step-by-step explanation:

We have:

The number of students = 213

Standard deviation of total quiz = 15

Standard deviation of final exam = 17

Correlation = 0.61

0.61x17/15

= 0.6913

If the student scored 17 points above the mean of total quiz marks

17 x 0.6913

= 11.7521

Her final exam grade would be 11.7521 above the mean

Answer:

[tex]\boxed {\tt 94.2 \ feet}[/tex]

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

[tex]c= \pi d[/tex]

where d is the diameter. We are given the radius, so let's find the diameter.

The diameter is twice the radius.

[tex]d=2r[/tex]

The radius is 15 feet.

[tex]d= 2 * 15 \ ft[/tex]

Multiply.

[tex]d= 30 \ ft[/tex]

Now we know the diameter. Substitute 30 feet in for d.

[tex]c= \pi d[/tex]

[tex]c=\pi * 30 \ ft[/tex]

We are using 3.14 for pi, so substitute it in.

[tex]c=3.14 * 30 \ ft[/tex]

Multiply.

[tex]c= 94.2 \ ft[/tex]

The circumference of the circle is 94.2 feet.

We have formula for this type Questions

c = πdc = πd

We have radius in the Question so we can easily find diameter.

The diameter is twice the radius.

=> d = 2rd = 2r

Also we know that the radius is 15 feet.

=> d = 2 * 15 \ ftd

=> d = 2∗15 ft

=> d = 30 \ ftd = 30 ft

=> c= \pi dc=πd

=> c=\pi * 30 \ ftc=π∗30 ft

=> c=3.14 * 30 \ ftc=3.14∗30 ft

=> c= 94.2 \ ftc=94.2 ft

[tex]Answer:\boxed{59\text{ and }31}[/tex]

[tex]Explanation:[/tex]

The first number can be written as x. The two numbers have a difference of 28, so the other number can be written as x-28. The total sum of the two numbers is 90. This can be written as an equation:

[tex]x+x-28=90[/tex]

Add 28 to both sides to leave the variable by itself:

[tex]x+x-28+28=90+28\\x+x=118[/tex]

Add the two x's:

[tex]x+x=118\\2x=118[/tex]

Divide both sides by 2:

[tex]\frac{2x}{2} =\frac{118}{2} \\x=59[/tex]

The first number is 59. The other number can be found by subtracting 28 from 59, since the difference between the two numbers is 28.

[tex]59-28=31[/tex]

To make sure the answer is correct, you can try adding the two numbers to check if they equal 90.

[tex]59+31=90\ \checkmark[/tex]

The answer is 59 and 31.

Hope this helps! ☺

Answer:

$15,712.20

Step-by-step explanation:

First you convert the percentage to decimal form out of 100 (which you divide)

8.7%/100 =  0.087

A = P(1 + rt)

A = $90,300(1 + 0.087 * 2)     ( * = multiplication)

I = $106,012.20 - $90,300= $15,712.20

Which you should get $15,712.20

Answer:

Step-by-step explanation:

First solve this like a normal equation:

-3x - 6 > 9

Add 6 to both sides:

-3x > 9 + 6

-3x > 15

Divide by -3 and remember to switch the inequality sign:

x < 15/(-3)

x < -5

Think about the graph of x = -5. It's a vertical line crossing the y-axis at x = -5. Now, we have x is less than -5. That means all the values less than -5 should be viable solutions. So, shade the part of the graph to the left of the vertical line.

Also, since we have x < -5 and not x ≤ -5, the line should be dotted.

Answer: When two polynomials are multiplied, the product is always a

polynomial.

Step-by-step explanation:

The only true property for polynomials is the third options because when you do multiply polynomials, you can only get a polynomial.

For instance;

Multiply (5x – 6y) by (7x – 4y)

= (5x – 6y)(7x – 4y)

= 35x² - 20xy - 42xy + 24y²

=  35x² - 62xy + 24y²

The result is a polynomial.

The rest of the options will not always yield polynomials.

Answer:

The number of people who became aware at the time T = 20 days = 2.5 million

Step-by-step explanation:

p(t) = 5 million

To = 0

T1 = 20 days

P(T1 ) = 50% * 5 = 2.5 million

hence to confirm the value of t where t = 20

P(T1) = [tex]6 - 4 (\frac{4}{5} )^{\frac{1}{50}t }[/tex]

        = [tex]6 - 4 (\frac{4}{5} )^{0.4}[/tex]

        = 6 - 4(0.9146)

p(20 ) ≈ 2.5 million

Answer:

t≈8.0927

Step-by-step explanation:

h(t) = -16t^2 + 128t +12

We want to find when h(t) is zero ( or when it hits the ground)

0 =  -16t^2 + 128t +12

Completing the square

Subtract 12 from each side

-12  =  -16t^2 + 128t

Divide each side by -16

-12/-16  =  -16/-16t^2 + 128/-16t

3/4 = t^2 -8t

Take the coefficient of t and divide it by 8

-8/2 = -4

Then square it

(-4) ^2 = 16

Add 16 to each side

16+3/4 = t^2 -8t+16

64/4 + 3/4= (t-4)^2

67/4 = (t-4)^2

Take the square root of each side

±sqrt(67/4) =sqrt( (t-4)^2)

±1/2sqrt(67) = (t-4)

Add 4 to each side

4 ±1/2sqrt(67) = t

The approximate values for t are

t≈-0.092676

t≈8.0927

Person to person payment is an online technology that allows customers to transfer their money and funds from their account to another account through mobile phones. A p2p app allows one user to send money to another user by using an app or website—transaction including anything from paying a dinner bill, rent, or contributing to charity.

The increased obtaining of online banking, mobile banking, and e-commerce by users has paved the way for greater use of person-to-person payments. In the payment markets sending money between smartphones has become an ordinary matter. According to Billtrust, young adults are using a person to person payment more than two generations.

Nearly half of smartphone owners regularly used p2p payment apps. Most people used p2p payment app because it offers better security or most of their peers use it.

Millennials have often led older Americans in their adoption and use of technology. More than 93% millennial (who turns ages 23 to 38 this year) have their smartphones. Similarly, the vast majority of millennials use social media, compared with smaller shares among old generations.
