PLEASEEE i REALLY need help!! This is due tonight!!
1. Think of two things that you can measure. Give one that requires high precision, or a low level of uncertainty. Give another that can have lower precision, or a higher level of uncertainty.
2. Explain why you made your choices. Why does one measurement need to be more precise than the other?
Problem 1
Two things you could measure is a person's height and the speed needed to reach the planet Mars. The person's height can be measured with a low level of precision, which means we don't need to be that accurate. We could say "that person is about 6 feet tall" and whoever is listening would get a sense of their height. In contrast, we need high precision for a rocket speed to Mars because getting this figure wrong would likely cause disaster down the road. Very complicated mathematics is essential to make sure we hit the target required in space.
===============================================
Problem 2
As mentioned, we need high precision when it comes to anything dealing with space travel. If the calculations are wrong, then the spacecraft could crash somehow. As one example where things went wrong, engineers used the wrong values and the Mars lander ended up crashing into the planet rather than landing safely. The high cost of such space exploration missions means that it's very crucial to get precise values as much as possible, to as accurate as possible. Things like discussing a person's height isn't that essential to be very precise as we can just relay estimates to whoever we're talking to. This informal setting doesn't demand as much accuracy compared to something like a rocket launch.

In a survey of U.S. Adults, 16% say they have had someone take over their email accounts without their permission. You randomly select 250 U.S. Adults and asked them whether they have had someone take over their email accounts without their permission. Find the probability that the number of U.S. Adults who say they have had someone take over their email accounts without their permission is : a. At most 40 b. Less than 45 c. Exactly 48
Answer:
a. At most 40
Step-by-step explanation:
If we take the survey that was done as a basis then we would use the 16% that was obtained as the number of overall US adults that have had their accounts used without their permission. Assuming that the 250 selected individuals were selected at random and without bias then those 250 would also be representative of the entire population. Therefore, we would simply need to multiply the number of selected individuals by the percentage in decimal form.
16 / 100 = 0.16
250 * 0.16 = 40
Finally, we can see that roughly 40 individuals would have had their email used without permission.

Dante slices potatoes at a steady pace to make fries. By the time he finishes, he has sliced 102 potatoes in 12 minutes. What is Dante's unit rate?
Answer: Dante slices 8.5 potatoes per minute.
Explanation: To find the unit rate look at the steps below.
102:12
12/12 gives us 1 minute and 102/12 gives us 8.5 We divide both numbers by 12 because if we divide 12 by 12 we get one minute and when we divide the other side it tells us how many potatoes Dante slices in one minute.

Juan sells a boat that he bought 5 years ago. He sells it for 60% less than he originally paid for it. If the original cost is b, write an expression that shows how much he sells the boat for
Answer:
b - 0.60b
= 0.40b
Step-by-step explanation:
The expression would be
here the original cost is b
And Juan sells it for 60% less than original price
So the expression is
= b - 0.60b
= 0.40b
This would be the expression that shows the selling price of the boat

how to find the angle?
please help I'll give BRAINIEST
** if there is two responses **
Answer:
m∠CDE = 37°
Step-by-step explanation:
Since, AB║CD and AC is a transversal line.
∠EAB ≅ ∠ECD [Alternate interior angles]
m∠EAB = m∠ECD = 25°
m∠CED + m∠AED = 180° [Linear pair of angles]
m∠CED + 62° = 180°
m∠CED = 180° - 62°
= 118°
By triangle sum theorem In ΔCDE,
m∠CED + m∠CDE + m∠ECD = 180°
118° + m∠CDE + 25° = 180°
m∠CDE + 143° = 180°
m∠CDE = 37°

Which of the following is an example of natural selection?
A) Hummingbirds drinking nectar from a plant.
B) Whales and dolphins swimming to the water’s surface to breathe.
C) Sloths making their homes high in trees to protect themselves from predators.
D) Brown-colored lizards surviving and reproducing because they are better able to camouflage themselves from predators.
Answer:
A) Hummingbirds drinking nectar from a plant.
Step-by-step explanation:
Here are some examples of natural selection: In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.

can someone plz help me
Answer:
x is less than or equal to negative 14.
Step-by-step explanation:
so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side
remove 5 from each side
-x/3=1/3-5
-x/3=14/3
multiply both sides by 3
-x=14
x=-14
so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14

Answer A has two of the five possibilities, and each section is equal so there is an equal probability for each. Add up the two possibilities for 2/5.
Multiply.
Your answer should be a monomial in standard form.
(4z^3)(-3z^3)
The answer you are looking for is -12z^6. To find this answer, you first multiply the two values (4 and -3).
4 × -3 = -12
Next, you multiply the variables and exponents. When multiplying with exponents, you simply just add the exponents together. For this instance, simple just add z3 and z3 to get z^6.
Thus meaning your final answer as a monomial is -12z^6. Here's an image to show how i solved the problem. I hope this helps!!
describe and correct the error in solving the proportion?
Answer: Choice B
They did not perform the cross multiplication properly
The correct step should be m*24 = 8*15 which solves to m = 5
========================================================
Explanation:
In general, if we had the equation A/B = C/D, then it cross multiplies to A*D = B*C. We refer to this as cross multiplication because of the shape made when we connect the terms (to figure out what multiplies with what). The diagram below shows what I mean.
So that's why m/8 = 15/24 cross multiplies to m*24 = 8*15
Simplifying things a bit leads to 24m = 120. Then we divide both sides by 24 to fully isolate m and we get m = 120/24 = 5. Therefore, m = 5.
Alaina needs to sell 225 boxes in order to be the top seller. She sells thin mints and samoas to all of her customers for a total of $628.00 in sales. The thin mints sell for $3.00 each and the samoas sell for $2.50 each. Which system of equations below could be used to find how many boxes of thin mints and samoas were sold?
Answer:
94 boxes of samoas
131 boxes of thin mints
Step-by-step explanation:
m=mints
s=samoas
s+m=225 m=225-s
s(2.5)+m(3)=628
2.5s+3m=628
substitute for m
2.5s+3(225-s)=628
2.5s+675-3s=628
reduce
-0.5s=-47
s=94
m=131
