A number, x, rounded to 1 decimal place is 3.7
Write down the error interval for x.
Answer:
The error in rounding a 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 12⋅0.1=0.05

1
⋅0.1=0.05. Since 3.7+0.05=3.753.7+0.05=3.75 and 3.7−0.05=3.653.7−0.05=3.65, then the error interval is \boxed{3.65\le x<3.75}.

The area of a circle is 201 square meters. Find
the radius.
Answer:
8.0meters
Step-by-step explanation:
Given data
Area of cirlce= 201 square meters
The expression for the area is
A=πr^2
Substitute our area
201= 3.14*r^2
r^2= 201/3.14
r^2= 64.01
square both sides
r= √64.01
r= 8.0 meters
Hence the radius is 8.0meters

Answer:

Step-by-step explanation:
What whole number best approximates the value of x?
The answer is 87
For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4
the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up
Hope this helps :)
Which statement best describes the association between the measures?
Answer:
the answer should be c
Step-by-step explanation:
positive association is just asking whether the line is positive or not. Since it's increasing (going from left to right) it's positive. Outliers refer to the two dots that are reallly far away from the rest.

Based on this data, what is a reasonable estimate of the probability that the Texas Sharpshooters score exactly
Answer:
The answer is "Its next hockey game is probably the Texas Sharpshooters who've had exactly 1 goal 0.5".
Step-by-step explanation:
The exploratory probabilities are called chances of possible dangers based on previous cases.
[tex]Experimental \ probabilities = \frac{Appropriate \ results}{Total\ results}[/tex]
The chance which Texas Sharpshooters will be scoring precisely
Next game of 1 goal
If demonstrated at the table:
Positive effects are 1 repeated 4 times
So, positive results [tex]= 4[/tex]
Outcomes total [tex]= 8[/tex]
Odds [tex]= \frac{4}{8} = 0.5[/tex]
The probability that Texas Sharpshooters will achieve exactly 1 goal is 0.5

The volume of a cylinder is 54π cubic inches and the height is 6 inches. Find the radius.
Answer:
The radius of the cylinder is 3 inches.
Step-by-step explanation:
For any given cylinder, the volume can be expressed as:
volume = [tex]\pi[/tex][tex]r^{2}[/tex]h
where r is the radius of its circular surface, and h is its height.
Given that: volume = 54π cubic inches, and the height = 6 inches.
then,
54[tex]\pi[/tex] = [tex]\pi[/tex] x [tex]r^{2}[/tex] x 6
54[tex]\pi[/tex] = 6[tex]\pi[/tex][tex]r^{2}[/tex]
[tex]r^{2}[/tex] = [tex]\frac{54\pi }{6\pi }[/tex]
= 9
r = [tex]\sqrt{9}[/tex]
r = 3
The radius of the cylinder is 3 inches.
