Answer: 3.75
Step-by-step explanation:
P=0.50, n=15
np= 0.5x15 gives 7.5
n(1-p)= 15x(1-0.5)=7.5
Both are greater than 5
Then Mean, u=np;15x0.5=7.5
Standard deviation, √np(1-p)
15x0.5(0.5)= 3.75

Which of the following correctly solves this equation? ( − 6 ) 2 − ( 6 ) ( 6 ) = 36 ( − 6 ) ( − 2 ) = 12 ( − 6 ) ( − 6 ) = 36 ( − 6 ) ( − 6 ) = − 36
The correct solution are: ( − 6 ) ( − 2 ) = 12 and ( − 6 ) ( − 6 ) = 36 .
Addition Sign Rules
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)
Multiplication Sign RulesThe rules for multiplication of numbers are:
+ + or - -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.
Option1( − 6 ) 2 − ( 6 ) ( 6 ) = 36
-12 -(36) = -12 -36 = -48 -> It is not the solution given in the exercise because -48 ≠ 36.
Option2( − 6 ) ( − 2 ) =12
12=12 -> It is the solution given in the exercise because 12=12.
Option3( − 6 ) ( − 6 ) = 36
36=36-> It is the solution given in the exercise because 36=36.
Option 4( − 6 ) ( − 6 ) = − 36
36≠ -36 -> It is not the solution given in the exercise because 36 ≠ -36.

Step-by-step explanation:
use a number line to find the difference-6.5 - 2
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.
Use the formula an = d (n − 1) + aj to write a formula for the arithmetic sequence below.
2, 6, 10, 14, 18,
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
Dawn and Mary work at Great Clips. They each make $11.50 per hour plus tips. Last weekend, Dawn worked x number of hours and earned $125 in tips. Mary worked y number of hours and earned $153 in tips. Dawn determined that using the expression 11.50x + 125 + 11.50y + 153 will calculate the amount the girls earned together last weekend. Select another expression the girls could use.Immersive Reader
Answer:
T=11.50(x +y) + 278Step-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

For the function H(t) = 3t - 5
Find when H(t) = 46
Answer:
t = 17
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

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.

Given Sine (t) = StartFraction 7 Over 25 EndFraction for StartFraction pi Over 2 EndFraction less-than t less-than pi, what is Cosine (t)?
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.
What is 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)
