Answer:
$1469
Step-by-step explanation:
diameter of deck = 12 m
diameter = 2*radius
thus
12 m = 2*radius
radius = 12m / 2 = 6 m
area of circle is given by [tex]\pi r^{2}[/tex]
where r is the radius
thus, area of given deck with radius = 12 m
[tex]\pi r^{2} = 3.14*12^{2} \\=> 3.14*144 = 452.16[/tex]
Thus, area of given deck is 452.16 meter square
given
The cost of the wood stain is $3.25 per square meter
cost of 1 meter square wood stain = $3.25
since we have to find to stain the entire deck which has area 452.16 meter square , we multiply both side of equation by 452.16
cost of 452.16 meter square wood stain = $3.25*452.16 = $1469.25
Thus,
it will cost $1469 to the nearest dollar for Emma to stain the entire deck
you roll three six sided dice. what is the probability that exactly two of the dice are odd?
Answer:
3C2 * (.5)^2 * (.5)^1
.375
Step-by-step explanation:
...
The probability that exactly two of the dice are odd is 3/8
What is probability?"It is finding out the possibilities of the occurrence of an event."
Formula to find the probability of an event:"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
What is Binomial theorem of probability?[tex]P=~ ^nC_r\times p^r \times q^{n-r}[/tex]
where, p is the probability of success and q is the probability of failure
For given example,
We roll three six sided dice.
We need to find the probability that exactly two of the dice are odd
the probability of success i. e. dice is odd would be,
⇒ p = 3/6
⇒ p = 1/2
So, the probability of failure would be,
⇒ q = 1 - p
⇒ q = 1 - 1/2
⇒ q = 1/2
Also, n = 3 and r = 2
Using Binomial distribution the required probability would be,
[tex]\Rightarrow P=~ ^nC_r\times p^r \times q^{n-r}\\\\\Rightarrow P=~ ^3C_2\times (\frac{1}{2} )^2 \times (\frac{1}{2} )^{3-2}\\\\\Rightarrow P =\frac{3!}{3!(3-2)!}\times \frac{1}{4} \times \frac{1}{2}\\\\ \Rightarrow \bold{P=\frac{3}{8}}[/tex]
Therefore, the probability that exactly two of the dice are odd is 3/8

Step-by-step explanation:
The expression ⁵√p¹¹ is equivalent to the given expression. The correct answer would be an option (C).
What are exponential expressions?Exponential expressions, as the name indicates, involve exponents. We already know that the exponent of a number (base) specifies how many times the number (base) has been multiplied.
The exponential expression is given in the question, as follows:
[tex]p^\frac{11}{5}[/tex]
We have to determine the equivalent expression to the given expression.
As per option (C), we have
⇒ ⁵√p¹¹
The above expression also can be written as:
⇒ [tex](p^{11})^\frac{1}{5}[/tex]
⇒ [tex](p^{11})^{\times}{(\frac{1}{5})}[/tex]
⇒ [tex]p^\frac{11}{5}[/tex]
Hence, we can conclude that the expression ⁵√p¹¹ is equivalent to the given expression.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is Y=-x+5. Thus, the correct option is C.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
The position of Allien in the coordinate plane is (0,5), the coordinate of the rocket is (5,0). The slope between the two is,
Slope, m = (0 - 5)/(5 - 0) = -5/5 = -1
The equation of the line can be written as,
y = -1x + C
substitute any one of the point in the equation,
0 = -1(5) + C
0 = -5 + C
C = 5
Hence, the equation of the line is Y=-x+5. Thus, the correct option is C.

What are Inverse trigonometric functions?
Inverse trigonometric functions are represented as arcsinx, arccosx, arcsecx, and so on.
The trigonometric functions that are used to calculate an angle from any of the angle's trigonometric ratios are called inverse functions.
The formula which is used to in inverse trigonometric equations are:
arcsinx = -arcsinx
arccosx = pi-arccosx
arctanx = -arctanx
arcsecx = pi - arcsecx
Solution:
The maximum values we obtain from the following equations are:
arcsinx = -1 to 1
arccosx = -1 to 1
arctanx = -pi/2 to pi/2
arcsecx = ∞
So the trigonometric functions which have the same maximum value is arcsinx and arccosx.

Sally wants to start a small business. She plans to sell snack packs by re-packing cookies and coffee sachets. Cookies come in packs of 10, while 3-in-1 coffee sachets come in packs of 12.
What is the smallest number of packs for each item should Sally buy if she wants to have packs with 1 cookie and 1 coffee sachet?
Answer: She needs 6 packs of cookies and 5 packs of coffee sachets.
Step-by-step explanation:
Cookies: come in packs of 10
Coffee sachets: come in packs of 12.
Sally wants to sell them in groups of 1 cookie and 1 coffee sachet, then we need to find a common multiple of 10 and 12. (the smallest one in this case).
To find the smallest common multiple, first let's find the largest common factor between 10 and 12.
If we write the numbers as a product of prime numbers, we have:
10 = 2*5
12 = 2*3*3
The only common factor is 2.
Then the smallest common multiple between 10 and 12 is equal to the product of 10 and 12 divided by the largest common factor between them, in this case is 2.
M = 10*12/6 = 60
Now to find the number of packages of each thing that she must buy, we need to divide 60 by the number of elements in each pack.
Cookies: 10 per pack
60/10 = 6
She needs 6 packs of cookies
Coffe: 12 per pack
60/12= 5
She needs 5 packs of coffee sachets.
