The inverse statement of "if number that has exactly two distinct factors is prime" is that B. If a number that does not has exactly two distinct factors is not prime"
How to illustrate the information?Each of the original statements is presupposed to be false in an inverse statement. "If it is not snowing" would be the polar opposite of "If it is snowing." "Then it is not chilly" would be the polar opposite of "then it is cold."
In this case, the inverse statement of "if number that has exactly two distinct factors is prime" is that B. If a number that does not has exactly two distinct factors is not prime.
Therefore, based on the information, the correct option is B.

Step-by-step explanation:
They have the same relative position to the parallel lines (in blue)
Does this curve appear to have a positive slope or a negative slope? Why do you suppose that is the case?
Answer:
It has a negative slope
Step-by-step explanation: It's going down
negative slope, because the quantity (y axis) decreases as the price (x axis) increases, creating a downward slope
The pressure, P (in lbs/ft2 ), in a pipe varies over time. Five times an hour, the pressure oscillates from a low of 90 to a high of 230 and then back to a low 90. The pressure at t = 0 is 90.
Question: Find a possible formula for P=f(t)
P=160-70*cos(2π*(1/12)*t)
• Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).
First, we find the amplitude by taking the difference between the peak values and dividing by two:
Amplitude=(230+90)/2=70
We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:
90+70=160
230-70=160
This tells us that the Center Value=160
The frequency that we are operating at is given as:
f = 5/hour
so in minutes
f=5*(1/60)/minute=5/60=1/12 per minute
So, combining everything we get
P=160-70*cos(2π*(1/12)*t)

Im getting 37in^2
But is saying incorrect
Answer:
42 in^2
Step-by-step explanation:
the 2 triangles have a total area of 3*4*(1/2)*2 = 12 in^2
the middle rectangle has an area of 5*2.5 = 12.5 in^2
the left rectangle has an area of 3*2.5 = 7.5 in^2
the right rectangle has an area of 4*2.5 = 10 in^2
adding up all 4 gets 42 in^2

The ration of red marbles to white ones is 13 to 12. If there are 3,081 red marbles how many white ones are there?
Answer:
2844
Step-by-step explanation:
13 is to 12 as 3081 is to x. 13/12 = 3081/x. 12 * 3081 = 13x.
36972 = 13x. divide both sides by 13, you're left with 2844.

A project consists of three tasks: A, B, and C. Task A is known to take five days for sure. Tasks B and C are each dependent on A. B takes five days. C takes seven days with a probability of 0.5 and three days with a probability of 0.5. What is the expected completion time of the project
Answer:
The expected completion time of the project is:
10 days.
Step-by-step explanation:
Duration of Task A = 5 days
Task B and C depend on Task A
This implies that Task A must be completed before Task B and C can be started.
To complete Task B will take 5 days
To complete Task C will take 5 days (7 * 0.5) + (3 * 0.5)
Since Task A takes 5 days and Tasks B and C depend on Task A and Task B takes 5 days and Task C takes expected time of 5 days, it means that the project can be completed in 10 days (5 + 5) if tasks B and C are simultaneously carried out.
The expected completion time of the project is
(i)10 days if B&C are mutually independent
(ii)15 days if B &C are mutually dependent
What is the expected completion time of a task?Expected completion time of a task= p1x1 + p2x2
Where
p1 & p2 are probabilities.
x1 and x2 are samples.
p1=p2=0.5
x1=7
x2=3
Expected completion time of task C= 0.5*7+0.5*3 = 5 days
Task B and C will be due till task A is not accomplished.
Total time to accomplish task A = 5 days
Total time to accomplish task B= 5 days
Expected time to accomplish task C = 5 days
If tasks B and C are mutually independent
expected time to complete the project = 5+5=10days
If task C depends on task B
Expected time to complete the project = 5+5+5 = 15 days.
Therefore
The expected completion time of the project is
(i)10 days if B&C are mutually independent
(ii)15 days if B and C are mutually dependent

The pH measurements of water specimens from various locations along a given river basin are Normally distributed with mean 8 and standard deviation 0.3. What is, approximately, the probability that the pH measurement of a randomly selected water specimen is a value between 7.5 and 8.2?
A. 0.3003
B. 0.6997
C. 0.9522
D. 0.9902
Answer:
0.699733
Step-by-step explanation:
Given that :
Mean (m) = 8
Standard deviation (s) = 0.3
Probability that pH is between 7. 5 and 8.2
Probability of pH < 7.5
P(x < 7.5)
The standardized score (Z) :
Z = (x - m) / s
Z = (7.5 - 8) / 0.3 = - 1.6667
p(Z < - 1.6667) = 0.047787 ( Z probability calculator)
Probability of pH < 8.2
P(x < 8.2)
The standardized score (Z) :
Z = (x - m) / s
Z = (8.2 - 8) / 0.3 = 0.6667
p(Z < 0.6667) = 0.74752 ( Z probability calculator)
Hence,
p(Z < 0.6667) - p(Z < - 1.6667)
0.74752 - 0.047787 = 0.699733

Each single digit gets its own box.
=======================================
Explanation:
Each row of three values must multiply to 12. We see that happening with the first two cuboids.
Cuboid A: 1*1*12 = 12
Cuboid B: 1*2*6 = 12
-------------
For cuboid C, we have two blank spaces multiplied with 4. Let's call these blank spaces x and y. We want to solve the equation x*y*4 = 12.
Divide both sides by 4 and you'll get x*y = 3
Since x and y are positive integers, this must mean either
x = 1 and y = 3
or
x = 3 and y = 1
Those are the only ways to multiply to 3 with two integers. But we can rule out the second case because the instructions say "Put the answers in order of size from left to right". Basically your teacher wants them sorted from smallest to largest. Refer to cuboid B for an example of what I mean.
So this means we have the values: 1, 3, 4 for cuboid C
---------------
Cuboid D is a similar story
Let x and y be the blank spaces. We can see that x*y*3 = 12 which becomes x*y = 4 after dividing both sides by 3.
This time we have three ways to do this and they are
x = 1 and y = 4x = 2 and y = 2x = 4 and y = 1We can immediately rule out x = 4 and y = 1 because we need the answers sorted from smallest to largest.
We can also rule out x = 1 and y = 4 because the sequence 1,4,3 is not fully sorted from smallest to largest. Note how this is effectively a repeat of cuboid C (just in a different order).
The only thing left is x = 2 and y = 2
For cuboid D we have these dimensions: 2, 2, 3

Since the test has twenty-five questions, and Peter got 80% correct...
80/100 = __/25 <--What number is the numerator?
Well, to get from 100 to 25, you have to divide by 4. 100/4 = 25.
Now, what is 80/4? If you do the math, you should get 20.

plz help me
Answer: simplifying
Step-by-step explanation:
2y + -10 = 6x
Reorder the terms:
-10 + 2y = 6x
Solving
-10 + 2y = 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 2y = 10 + 6x
Combine like terms: -10 + 10 = 0
0 + 2y = 10 + 6x
2y = 10 + 6x
Divide each side by '2'.
y = 5 + 3x
Simplifying
y = 5 + 3x
