Answer:
0.00064
0.049
0.185
0.234
Step-by-step explanation:
Using binomial distribution formula :
P(x = x) = nCx * p^x * (1 - p)^(n-x)
p = 0.65
1 - p = 1 - 0.65 = 0.35
n = 7
(A) None will be divorced?
P(x = 0) : 7C0 * 0.65^0 * 0.35^7
= 1 * 1 * 0.00064339296875
= 0.00064
(B) All will be divorced?
P(x = 7) : 7C7 * 0.65^7 * 0.35^0
1 * 0.04902227890625 * 1
= 0.049
(C) Exactly 6 will be divorced?
P(x = 6) : 7C6 * 0.65^6 * 0.35^1
7 * 0.075418890625 * 0.35
= 0.18477628203125
= 0.185
(D) At least 6 will be divorced?
P(x ≥ 6) = p(6) + p(7)
P(6) = 0.185
P(7) = 0.049
P(x ≥ 6) = 0.185 + 0.049 = 0.234

Teresa went to a bakery to buy bagels. Each bagel at the bakery was the same price. Teresa paid $5.00 for 4 bagels.
Answer:$1.25 per bagel
Step-by-step explanation:
5/4=1.25
The cost of each bagels is $1.25.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Teresa went to a bakery to buy bagels.
Teresa paid $5.00 for 4 bagels.
Cost of each bagel = Total cost/Number of bagels
= 5/4
= $1.25
Therefore, the cost of each bagels is $1.25.

39. State the equation for the line described below.
40. State the equation of the line that passes through the points (–7, 5) and (–12, 4).
Picture is attached
Answer:
Step-by-step explanation:
39). y = [tex]-\frac{7}{8}[/tex] x + 3
40). m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
(- 7, 5)
( - 12, 4)
m = ( 4 - 5 ) / ( - 12 + 7) = 1/5
y - 5 = (1/5)(x + 7) ⇒ y = [tex]\frac{1}{5}[/tex] x + 6.4

Answer:
[tex]y\approx 11.9[/tex]
Step-by-step explanation:
Here, we have the known angle sandwiched between two known sides.
So, we have SAS.
And we want to find the side opposite to the angle.
Therefore, we can use the Law of Cosines:
[tex]c^2=a^2+b^2-2ab\cos(C)\\[/tex]
Again, it is important what we substitute.
a and b are the two side lengths. So, we will substitute 8 for a and 13 for b.
C is our angle. So, substitute 64 for C.
And c is what we’re trying to solve.
Therefore:
[tex]c^2=(8)^2+(13)^2-2(8)(13)\cos(64)[/tex]
Simplify:
[tex]c^2=64+169-208\cos(64)[/tex]
Add:
[tex]c^2=233-208\cos(64)[/tex]
Take the square root of both sides:
[tex]c=\sqrt{233-\cos(64})[/tex]
Use a calculator. So, c is approximately:
[tex]c\approx11.9[/tex]
The c is our y. So, y is approximately 11.9 units.

f(x)=−x+4
g(x)=x−5
Find: f(x)+g(x)
Solution:
Answer:
-1 because when you add both functions thats what you get.
The sum of the functions f(x) and g(x) is -1.
What is a function?
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. A common notation for a function is "f(x)," where x denotes the input value. Example: f(x) = x/2.
What will be the sum of given functions?Add both the functions as,
f(x)+g(x)=-x+4+x-5
Collect the like terms of right side,
f(x)+g(x)=-1
Therefore, the sum of the function f(x) and g(x) is -1.
