Answer:
6x + 14
Step-by-step explanation:
Givens
P = s1 + s2 + s3
s1 = x
s2 = 4x + 12
s3 = x +2
Solution
P = x + 4x + 12 + x + 2

The sample has a mean of 19.4 mg and a standard deviation of 3.23 mg. Use a 0.05 significance level to test the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg, which is the mean for unfiltered king size cigarettes.Please select all TRUE statements from those givem below.1. For this hypothesis test the P-value = .0072. There is sufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than21.1 mg.3. For this hypothesis test; H0; 1.1 H1: 21.14. For this hypothesis test the test statistic is t = -2.6325. service.php?service=cache&name=55e1f2083
Answer:
h0:u ≥ 21.1
h1: u < 21.1
t statistics = -2.632
pvalu = 0.007
there is sufficient evidence to support claim
Step-by-step explanation:
null hypothesis
h0 = u≥21.1
alternative = u < 21.1
to get test statistics
barx - u / s/√n
= 19.4 - 21.1 / 3.23/√25
= -2.632
we calculate for the p value given this test statistics and the degree of freedom = 25-1 = 24
lest tailed p value = 0.0073 this is approximately 0.007
p value is less than the level of significance so we reject h0
we conclude that we have enough evidence to support h1, mean tar conent is less than 21.1
Two bags of carrots cost a total of $4.00. If each bag weighs half a pound, what is the cost, in dollars, per ounce of carrots?
Answer:

Step-by-step explanation:
Brenda and Sam are going to stay at the hotel for one night. It costs a total of £84 to stay at the hotel for one night. Brenda pays a deposit of £20 towards the total cost. Brenda says to Sam, 'We will share the total cost equally.' How much does each person have left to pay?
Answer:
£32 and £32
Step-by-step explanation:
The computation of the amount that should be left and equally distributed is shown below:
The cost of hotel for one night is £84
Brenda has make a deposit of £20
So, the remaining amount left is
= £84 - £20
= £64
Now this amount should be equally distributed between them i.e. £32 and £32

Select the graph that correctly represents ƒ(x) = –2(x + 4)2 – 1.Find the equation of the parabola with its focus at (3,4) and its directrix y = 0.
Answer:
Equation of parabola: 8*(y - 2) = (x - 3)^2
or
y = (1/8)*(x - 3)^2 + 2
Step-by-step explanation:
focus at (3,4) and its directrix y = 0.
Focus equation: (h, k + c) = (3, 4)
Directrix equation y = k - c = 0
so h = 3, k + c = 4, k - c = 0
Solve the system : k + c = 4 and k - c = 0
add the equations together: k + c + k - c = 4 + 0
2k = 4
k = 2
so k + c = 4, 2 + c = 4, c = 2
4c (y - k) = (x - h)^2
4*2 *(y - 2) = (x - 3)^2
8*(y - 2) = (x - 3)^2

Answer:
[tex]cos(x)[/tex]
Step-by-step explanation:
Let's recall the definition of the trigonometric identities in place:
[tex]cot(x)=\frac{1}{tan(x)} =\frac{cos(x)}{sin(x)}[/tex] and
[tex]csc(x)=\frac{1}{sin(x)}[/tex]
Then, we substitute and simplify as follows:
[tex]\frac{cot(x)}{csc(x)}=cot(x)*\frac{1}{csc(x)}=\frac{cos(x)}{sin(x)}*sin(x)=cos(x)[/tex]

Answer:
100=15.50p-7.00
6 people
(p can be any variable)
Step-by-step explanation:
100 is the amount of money Ms. Hernandez will spend, 7 is the amount she will have to spend on parking, and 15.50 is the cost per person to go to the zoo.
How to solve the equation
100=15.50p-7 You would first have to isolate the variable, add 7 to both sides107=15.50p You would then divide each side by 15.50 to completely isolate p6.9032258=p Since you cannot have a fraction of a person, the total amount of people that can go to the zoo, including Ms. Hernandez is 6

I assume that 16 m is the radius, not a diameter.
A table cloth has an area of 64 ft.2
A. What is the diameter of that table?
B. What is the circumference of that table?
Answer:
A) Diameter = 9.03 ft
B) Circumference = 28.35 ft
Step-by-step explanation:
64 = πR²
R² = 64/3.14 = 20.38
Radius = 4.51 ft
Diameter = 2(4.51) = 9.03 ft
Circumference = 9.03 x 3.14 = 28.35 ft
Which of the following is one way to potentially increase your savings?
A. increase discretionary spending
B. reduce your income
C. reduce discretionary spending
D. increase your expenses
Answer: C
Step-by-step explanation:
Reducing discretionary spending is one way to potentially increase one's savings. Thus, option C is correct.
What is savings?The amount of money earned that is not used for immediate expenses is saved. It is money that is saved up and really not spent buying.
This disposable income, used in order to pay for all necessary and semi-products and services, comes from their discretionary income. A discretionary income is the sum of revenue we have left over after covering all of the ones living expenditures.
Discretionary revenue refers to the sum of money left over after all this has been met. Depending on the person's preferences, they can choose to spend it on products and services or save/invest it. Other necessary costs also occur.
Therefore, option C is the correct option.

Can you please help me figure out where to start so I can teach this to my child?
Answer:
all of the brackets first
Answer:
Step-by-step explanation:
Those consecutive angles must sum to 180 degrees.
7x+9+7y-4=180
7x+7y+5=180
7x+7y=175
x+y=25
x=25-y
We also have
11x-1+2y+5=180
11x+2y+4=180
11x+2y=176, using x=25-y that we found above makes this
11(25-y)+2y=176
275-11y+2y=176
-9y+275=176
-9y=-99
y=11, and since x=25-y
x=25-11
x=14
Finally
z+7x+9=180
z+7x=171
z=171-7x, we found that x=14 earlier so
z=171-7(14)
z=171-98
z=73
So the three values are
x=14, y=11, and z=73 degrees.
