Answer:
The value of n is 7.
Step-by-step explanation:
For each teen, there are only two possible outcomes. Either they buy soda at least once each week, or they do not. Since they were selected randomly, the teens are independent of each other, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
In the binomial distribution, we have that n is the size of the sample. In this question, seven teens are randomly selected, which means that the value of n is 7.

Can anyone please help me figure this problem out?
Answer:
x = 12
Step-by-step explanation:
Step(i):-
From graph,
The angle of the triangle ∝ = 45°
Given hypotenuse of the triangle
AC = 12√2 and AB = x
Step(ii):-
we will choose sine function
[tex]sin\alpha = \frac{opposite side}{hypotenuse}[/tex]
[tex]sin\alpha = \frac{x}{12\sqrt{2} }[/tex]
Given that an angle ∝ = 45°
[tex]sin45 = \frac{x}{12\sqrt{2} }[/tex]
[tex]\frac{1}{\sqrt{2} } = \frac{x}{12\sqrt{2} }[/tex]
[tex]\frac{1}{1 } = \frac{x}{12}[/tex]
x = 12
Final answer:-
x = 12

Donte scored 55 on his mastery exam. What percent did Donte score?
Answer: See explanation
Step-by-step explanation:
Your question isn't complete. First and foremost, to be able to solve this, we need to know the total marks of the examination.
Let's assume that the total marks for the exam is 80. Since Donte scored 55 on his mastery exam, the percent that he score will be:
= 55/80 × 100
= 68.75%

A tourist in Ireland wants to visit five different cities. If the route is
randomly selected, what is the probability that the tourist will visit the
cities in alphabetical order? Round your answer to three decimal places.
0.004
1.234
0.023
0.008
Answer:
0.008
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Total outcomes:
He will visit 5 different cities. So the total number of ways this can happen is an arrangment of 5 elements, that is:
[tex]T = A_{5} = 5! = 120[/tex]
Desired outcome:
In alphabetical order, so only one possible outcome, which means that [tex]D = 1[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{120} = 0.008[/tex
the formula of ONE INTERIOR ANGLE of a REGULAR polygon.
Answer:
180° - (360/n)°, where n is the number of sides of the polygon.
Step-by-step explanation:
Polygon has n sides.
Divide the polygon radially into n congruent, isosceles triangles.
For each triangle:
vertex angle = (360/n)°
sum of base angles = 180° - vertex angle = 180° - (360/n)°
Each interior angle of the n-gon = 180° - (360/n)°

About how many years will it take for $8500 to reach $12,000 at a simple interest rate of 3.5%
Answer:12
Step-by-step explanation:
8500 x 35% = 297.50 in simple interest per year
12000 - 8500 = 3500 in interest earned in total
3500/297.5 = 11.76 number of years to make total interest from amount per year.
If you round up, almost 12 years .

Jack and Jill both start at point A. They each walk in a straight line at an angle of 105° to each other. After 45 minutes Jack has walked 4.5km and Jill has walked 6km. How far apart are they? Round to the nearest hundredth.
Answer: The distance between them is 8.38 km
Step-by-step explanation:
Let's suppose both of them start at the point (0km, 0km), and that Jack walks along the positive x-axis, then Jill walks at an angle of 105° measured from the positive x-axis.
After 45 minutes, jack has walked 4.5km, then if his initial position was (0 km, 0 km)
Then his new position will be (4.5km, 0km)
Jill has walked 6km, but we need to write this in rectangular components.
We can think in this as a triangle rectangle, then the components will be:
x-component = 6 km*cos(105°) = -1.55 km
y-component = 6km*sin(105°) = 5.80 km
Then the new position of Jill is ( -1.55km, 5.80km)
Now, we know that the distance between two points (a, b) and (c, d) is:
Distance = √( (a - c)^2 + (b - d)^2)
Then the distance between Jill and Jack will be equal to the distance between ( -1.55km, 5.80km) and (4.5km, 0km)
This is:
Distance = √( (-1.55km - 4.5km)^2 + (5.80km - 0km)^2)
Distance = 8.38 km
This means that they are 8.38km apart.
Specify the set of B by giving a written description of It’s element where B={ 0,1,4,9,16,25}
Answer:
B = { square numbers less than 30 }.
or
B = {x/x is square of a whole number; [tex]0 \leq x \leq 5[/tex] }
Step-by-step explanation:
Given the set B
B={ 0,1,4,9,16,25}
Let us check the elements in set B.
[tex]x = 0 = 0^{2}[/tex]
[tex]x\:=\:1\:=\:1^2[/tex]
[tex]x\:=\:4\:=\:2^2[/tex]
[tex]x\:=\:9\:=\:3^2[/tex]
[tex]x\:=\:16\:=\:4^2[/tex]
[tex]x\:=\:25\:=\:5^2[/tex]
It is clear that each element in set B is a square of a whole number.
Thus, we can specify set of B by giving a written description of Its element in a variety of ways, such as:
B = { square numbers less than 30 }.
or
B = {x/x is square of a whole number; [tex]0 \leq x \leq 5[/tex] }

A DVD player is regularly priced at 79.95 and is on sale for 30% off. What is the discount?
Answer:
$2.40 or $77.55
Step-by-step explanation:
I don't know if you are asking for how much off or what, so I'm doing both
First, we have to find how much we have to take off or what is 30% of 79.95 so our equation is:
79.95 x 0.03 = 2.40
So 30% of 79.95 is $2.40
To find how much our new price sale is, we have to take that $2.40 off so our equation is:
79.95 - 2.4 = 77.55
So our discount price is $77.55
hope this helps:)
Given the function f(x) = 0.5 |x– 4| – 3, for what values of x is f(x) =7
O x = -24, x = 16
O x= -16, x = 24
O x= -1, x = 9
O x= 1, x= -9
Answer:
-16,24 B
Step-by-step explanation:
To solve this simplify the equation until it's just the absolute value brackets
7=.5 |x-4|-3
Add 3 to both sides and divide by .5 to get
20=|x-4|
Then solve this equation where the leftmost side is a positive and then a negative
So 20=x-4
x=24
24 is one of our answers
Then solve it when the left side is a negative
-20=x-4
x=-16 which is the other answer

Consider the expression 40+24 Find the greatest common factor of the two numbers and rewrite the expression using the distributive property
Answer:
Greatest Common Factor of 40+24 is 8
Rewriting the expression using the distributive property we get 8(5+3) =8(5)+8(3)
Step-by-step explanation:
We need to F=find the greatest common factor of the two numbers 40+24 and rewrite the expression using the distributive property
Greatest Common Factor:The greatest number that is divisible by both numbers is known as greatest common factor.
So, Greatest Common Factor of 40+24 is 8
Now, Taking 8 common we get: 8(5+3)
Distributive property:It is written as: a(b+c) = ab+ac
So, we have 8(5+3) =8(5)+8(3)
Rewriting the expression using the distributive property we get 8(5+3) =8(5)+8(3)
