Suppose that a recent poll found that 50 ​% of adults in a certain country believe that the overall state of moral values is poor. If a survey of a random sample of 15 adults in this country is conducted in which they are asked to disclose their feelings on the overall state of moral​ values, complete parts​ (a) through​ (e) below.

Answer:

Answer is -24/25.

Step-by-step explanation:

Got it right on egde2020

The value of cos (t) is - (24/25), as per  the relation between the sine and cosine of an angle.

For any angle 'Ф',  the relation between the sine and cosine of an angle is:

sin² (Ф) + cos² (Ф) = 1, when 0 < Ф < (π/2)

Given equation,

sin (t) = (7/25), for (π/2) < t < π

Here, 't' is in the second quadrant.

Therefore, sine is positive here.

However, cosine is negative there.

Therefore, the value of cos (t) is

= - √[1 - sin² (t)]

= - √[1 - (7/25)²]

= - √[1 - (49/625)]

= - √(576/625)

= - (24/25)

Answer:

Step-by-step explanation:

in this problem we are looking at an alternative expression to the given expression for the total earning which is

Given data

T=11.50x + 125 + 11.50y + 153

let us collect like terms we have

T=11.50x + 11.50y + 153+ 125

T=11.50x + 11.50y +278

we can factor out 11.5 since it is common

T=11.50(x +y) + 278

The alternative expression the girls could use is

T=11.50(x +y) + 278

The correct solution are:  ( − 6 ) ( − 2 ) = 12 and  ( − 6 ) ( − 6 ) = 36 .

Here it is important to remember the rules for the  addition of integers numbers:

+  +   Add  Final result (+) - Final result (+)  

-   -   Add  Final result (-) - Final result (-)  

+  -   Subtract - Final result (the sign of the integer having a greater value)

-   +  Subtract - Final result (the sign of the integer having a greater value)

The rules for multiplication of numbers are:

The result presents a positive sign (+) because the signs are the same.

  +  - or   -   +

The result presents a negative sign (-) because the signs are different.

For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.

        ( − 6 ) 2 − ( 6 ) ( 6 ) = 36

        -12 -(36) = -12 -36 = -48 -> It is not the solution given in the exercise because  -48 ≠ 36.

        ( − 6 ) ( − 2 ) =12

                12=12 -> It is the solution given in the exercise because  12=12.

      ( − 6 ) ( − 6 ) = 36

               36=36-> It is the solution given in the exercise because  36=36.

       ( − 6 ) ( − 6 ) = − 36

            36≠ -36 -> It is not the solution given in the exercise because  36 ≠ -36.

Answer:

[tex]a_{n}[/tex] = 4n - 2

Step-by-step explanation:

There is a common difference d between consecutive terms in the sequence, that is

6 - 2 = 10 - 6 = 14 - 10 = 18 - 14 = 4

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 4 , thus

[tex]a_{n}[/tex] = 2 + 4(n - 1) = 2 + 4n - 4 = 4n - 2

Answer:

After 5 hours.

35 bacteria cells.

Step-by-step explanation:

Andy’s population is represented by [tex]B=6x+5.[/tex]

Samantha’s population is represented by [tex]B=2^x+3[/tex]

Where B represents the total population given the number of hours x.

We want to find at what hour will their population be the same. We are told to use graphing technology.

Graphing them, we will get the graphs below.

Graphically, their population will be the same where the two graphs intersect.

So, we can see that they intersect at (5, 35).

Therefore, after 5 hours, the total number of bacteria cells for both experiments will be the same.

And the total number of bacteria at that time will be 35 bacteria cell.

3/4 + 1/4 = 4/4 = 1

If the number is the same for the numerator and denominator it adds up to 1.

Answer:

The answer would be -8.5

Step-by-step explanation:

If you start at -6.5, to find the difference (subtract) you would move left two whole spaces to get to -8.5.

On the other hand, if you were to start at 6.5 and subtract 2, your answer would be 4.5.

It depends if your first number is negative or positive.

Step-by-step explanation:

Plug in 46 for H(t) into the above equation and solve for t.

46 = 3t - 5 (add 5 to both sides)

51 = 3t (divide both sides by 3 to isolate t)

17 = t or t = 17
