Write the error interval for x , where x=4.7 , truncated to 1 decimal place.
Error interval for x is 4.65 ≤ x < 4.75.
What is error interval?Error intervals are the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated.
The error is rounding the number is half of the unit of measure.
The number was rounded to the nearest 0.1 unit. so the error is half of 0.1 which is [tex]\frac{1}{2}[/tex] × [tex]0.1[/tex] = 0.05
∵ 4.7 + 0.05 = 4.75
and 4.7 - 0.05 = 4.65
Error interval for x is 4.65 ≤ x < 4.75.

An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded. Which could be the number of scoops sold if they rounded to the nearest thousand? Choose all answers that apply
Answer:
B - 12,111
C - 11,589
Step-by-step explanation:
Here are the options
A - 10, 999
B - 12,111
C - 11,589
In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit
Rounding off 10,999 to the nearest thousand is 11,000
the hundred figure is greater than 5, so one is added to the thousand figure. The
Rounding off 12,111 to the nearest thousand is 12,000
the hundred figure is less than 5, so zero is added to the thousand figure.
Rounding off 11,589 to the nearest thousand is 12,000
the hundred figure is equal to 5, so one is added to the thousand figure.
Alyssa opened a bank account that earns 1.5% simple interest. Over 4 years, she earned $72 in interest. How much money did
she initially deposit into the bank account?
Answer:
1200
Step-by-step explanation:
72/4=$18 interest each year
amount x interest rate = interest
amount x .015 = 18
amount = 18/.015

A honeydew melon is shaped like a sphere with a diameter of 8 inches. Which value is closest to the volume of the melon?
Answer:
The volume of sphere = 268.08
Step-by-step explanation:
Below is the calculation for the volume of melon (sphere).
Given the diameter of the sphere is = 8 inches
Now find the radius by dividing the diameter by 2 = 8/2 = 4 inches
Now use the below formula to find the volume.
The volume of sphere = [tex]\frac{4}{3} \times \pi \times r^{3}[/tex]
The volume of sphere = 268.08

A stock loses half its value each week. If the stock started at $125, what is it worth after 4 weeks?
Answer: 7.81
The formula is
y = 125* (1/2)^4
y = 125 / 16
y = 7.81
So at the end of the 4th week, the stock is worth only 7.81 dollars.
If that is not the motive and the first week doesn't count then the formula changes to...
y = 125 * (1/2)^(n-1)
y = 125 * (1/2)^3
y = 15.625 could be the other answer if you looked at it in that perspective
However, I would go with 7.81 as the answer.
Hope I helped :)

What is the area of this polygon?
___ units2
If you can please explain with you answer!! Thank you so much!
Answer:
39 units
Step-by-step explanation:
area of polygon = area of rectangle VERD + area of triangle MVR
[length of rectangle (6) * width of rectangle (5)] + [1/2 * 3 (height of triangle) * 6 (height of triangle)] = area of polygon
(6*5) + (1/2*3*6) = area of polygon
30 + 9 = area of polygon
area of polygon = 39
use graph to answer question
Answer:
cos(θ) = 3/5
Step-by-step explanation:
We can think of this situation as a triangle rectangle (you can see it in the image below).
Here, we have a triangle rectangle with an angle θ, such that the adjacent cathetus to θ is 3 units long, and the cathetus opposite to θ is 4 units long.
Here we want to find cos(θ).
You should remember:
cos(θ) = (adjacent cathetus)/(hypotenuse)
We already know that the adjacent cathetus is equal to 3.
And for the hypotenuse, we can use the Pythagorean's theorem, which says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, this is:
3^2 + 4^2 = H^2
We can solve this for H, to get:
H = √( 3^2 + 4^2) = √(9 + 16) = √25 = 5
The hypotenuse is 5 units long.
Then we have:
cos(θ) = (adjacent cathetus)/(hypotenuse)
cos(θ) = 3/5
