Answer:
a) According to probability theory, the following are possible:
(1) The probability that a customer will buy 5 items in a single purchase is 30%. This represents a 0.30 chance of the customer buying 5 items.
(3) The probability that a customer will buy 3 items in a single purchase is 99% This means that there a 0.99 chance that the customer will buy 3 items.
b) According to probability theory, the following are not possible:
2) The probability that a customer will buy 3 items in a single purchase is 101%. Probability is always equal to 1 or 100%. It cannot exceed 100%.
(4) The probability that a customer will buy 8 item. This part lacks the necessary information to solve the problem.
Step-by-step explanation:
Probability describes the likelihood or chance of an event happening out of the many possible events that can take place. The sum of all probabilities for a particular event is always equal to 1. This shows that probability does not exceed 100%.

y = 10 b = 6
Answer:
The answer is -60 (I believe)
Step-by-step explanation:
3(-10)-5(6)
-30-30 = -30+-30
-30+-30= -60
The answer is -60
Step-by-step explanation:
If y = 10 and b = 6 Then
3(-y) - 5b
= 3 *( - 10 ) - 5 * 6
= - 30 - 30
= - 60

The number of calories in a one ounce serving of a certain chicken sandwich is a random variable with mean 110 calories. The number of calories in a full cup of lemonade is a random variable with mean 140 calories. For lunch, you eat one ounce of the chicken sandwich and LaTeX: \frac{1}{2}1 2 cup of lemonade. Let K be the random variable that represents the total number of calories in this lunch. The mean of K is
Answer:
The mean of K is 180 calories.
Step-by-step explanation:
Mean of a sum of normal distribution:
The mean of a sum of normal distributions is the sums of the mean.
In this question:
Lunch:
One ounce of chicken sandwich, with mean 110 calories.
Half a cup of lemonade, with mean 140/2 = 70 calories.
Let K be the random variable that represents the total number of calories in this lunch. The mean of K is
110 + 70 = 180 calories
The mean of K is 180 calories.

Use the table to write a linear function that relates y to I.

Answer:
y = -7
Step-by-step explanation:
✔️Find the slope (m) using any two pairs of values, say (0, -7) and (2, -7):
Slope (m) = ∆y/∆x = (-7 -(-7))/(2 - 0) = 0/2 = 0
Slope (m) = 0
✔️Find y-intercept (b):
y-intercept is the value of y when x = 0. From the table, when x = 0, y = -7.
Therefore, y-intercept (b) = -7
✔️ Substitute m = 0 and b = -7 into y = mx + b (slope-intercept form):
y = 0(x) + (-7)
y = -7
what number multiplied by 0.5, Multiplied by 1/3, square the number, add one, equals 50?
Answer:
42
Step-by-step explanation:
Let that number be x
x is multiplied by 0.5, 1/3, then squared
(0.5/3 x)^2
Add 1: (0.5/3 x)^2 +1
Make it equal to 50
: (0.5/3 x)^2 +1 = 50 now solve
(0.5/3 x)^2 =50-1
(0.5/3 x)^2 =49
square root both sides ending up with:
0.5/3 x=7
solve for x
x=42

Use the net to find the surface area of the cylinder. 6ft and 7ft
Answer:
A. 84 pi feet^2
Step-by-step explanation:
So the lateral area is the rectangular piece on the net
In order for it to be an actual cylinder the 2 circles are congruent
Therefore the radi, area, circumference ect.. are the same.
So the only missing measurement we need to find the lateral area is the length of the rectangular piece
If you visualize a cylinder, the rectangular piece goes around the perimeter/circumference of the circle
So that means that the length of the rectangle is the circumference of the circle
Circumference = 2*pi*r
2 * pi * 6
= 12 pi
Then 7*12 pi
=84 pi
So the lateral area is 84 pi

How do scientists identify tectonically active regions
Answer: plate tectonics
Step-by-step explanation:Most earthquakes and volcanic eruptions do not strike randomly but occur in specific areas, such as along plate boundaries. One such area is the circum-Pacific Ring of Fire, where the Pacific Plate meets many surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.

This is the answer:
Mass of earth: 5.97200e21 or 5.97200000000000000000000000
Mass of planes: 210000
Now, we have to divide the mass of the earth into the amount of planes.
For example, Earth/Planes.
And the answer is: 2.84380952e5. Or 2.8438095200000. I hope this helps!
At what point do the graphs of the lines y=9x+2 and y=-3+12 intersect?
Answer:
(0.8333, 9.5)
Step-by-step explanation:
set them equal
9x+2=-3x+12
12x=10
x=0.8333
plug x into the equation
9(0.8333)+2 = 9.5
-3(0.8333)+12 = 9.5
Answer:
(5/3,17)
Step-by-step explanation:
If your second equation is y=-3x+12 your answer will be (5/3,17)
Javier will ask a survey question to determine the average number of times per month people around the United States shop for groceries. Which sample should Javier use to get results that are the most representative of the total population? A. A random sample of 1,000 people from each of the 50 states B. A random sample of 1,000 people from his town C. A random sample of 1,000 people from his state D. A random sample of 1,000 people from 5 local grocery stores
Answer:
a
Step-by-step explanation:
Because if he picks b which is only from his own town the rest of the states will not be included. If he pick only from his own states then he only represents his own states and for d 5 local grocery store we don't know which country it represents A is the correct answer.
The sample which Javier use to get results is a random sample of 1,000 people from each of the 50 states.
What is random sample?
Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.
Here, sample which Javier will ask a survey question to determine the average number of times per month people around the United States shop for groceries.
To find the sample, which Javier use to get results that are the most representative of the total population, we have to check all the options.
Lets, check all the options,
A. A random sample of 1,000 people from each of the 50 states-This includes the sample from each state. This gives the fair and equal chance to be chosen the sample from the country. Hence, this is the correct option. B. A random sample of 1,000 people from his town-This option only include his own town and does not include any other town. Hence, this is not the correct option.C. A random sample of 1,000 people from his state-This option only include his own state and does not include any other state. Hence, this is not the correct option. D. A random sample of 1,000 people from 5 local groceries stores-This 5 local store may represent his country or any other country. Hence, this is not the correct option.Hence, the sample which Javier use to get results is a random sample of 1,000 people from each of the 50 states.

Angle ABF is 77
a) Find the size of angle x.
b) Which one of these justifies your answer?
A- corresponding angles
B - alternate angles
C- vertically opposite angles
Answer:
a) 77 b)B
Step-by-step explanation:
letterF is the same as 77 meaning that X will be the same as letterF cause the are vertically opposite angles.
I just did the question on math watch.
The measure of the angle ∠BFH that is 'x' will be 77 degrees. Then the correct option is B.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Alternate angle - If two lines are parallel then the third line will make z -an angle and z-angles equal angles with the parallel lines.
Line AD is parallel to line EH. And the line CG is the transversal line to line AD and EH.
The angle ∠FAB is congruent with the angle ∠BFH. Because they are alternate angles. Then we have
∠BFH = ∠FAB
x = 77°
The measure of the angle ∠BFH that is 'x' will be 77 degrees. Then the correct option is B.
