A number x is rounded to 1 decimal place and its 3.7
write down the error interval for x
Answers
The error interval for x would be (3.65, 3.75), indicating that the true value of x lies within this range.
Given that a number x is rounded to 1 decimal place and its 3.7.
We need to find the error of the interval for x,
To determine the error interval for the rounded number 3.7, we need to consider the possible range of values that could have been rounded to 3.7 when rounded to 1 decimal place.
When rounding to 1 decimal place, we look at the digit immediately to the right of the decimal point. If this digit is 5 or greater, we round up. If it is less than 5, we round down.
In this case, 3.7 is the rounded value, which means the original number could have been rounded up from a value greater than or equal to 3.65 or rounded down from a value less than 3.75.
Therefore, the error interval for x would be (3.65, 3.75).

(8,1), (-2,-5) midepoint
Answers
Answer:
(3, -2)
Step-by-step explanation:
The x-coordinate of the midpoint of the line segment connecting (8, 1) and (-2, -5) is -2 plus half the horizontal distance from -2 to 8, which is 10, or 5. We add 5 to -2, obtaining 3 units.
The y-coordinate of the midpoint is found similarly. The vertical distance between the two given points is 1 - (-5), or 6 units. Half of that is 3 units. Adding 3 units to -5 yields -2.
The midpoint is (3, -2).
Thus, the coordinates of the midpoint at (-7, 6)

Answer:
-62
Step-by-step explanation:
180-w+49(angles on a straight line=180)
angles on a triangle=180
Hence,
180-w+49+w+17+w-4=180
collect the like terms
180+49+17-4+w+w-w=180
242+w=180
Take 180 to the other side and also w
242-180=-w
62=-w same as w=-62

s^3–1=( ) (s^2+s+1). Help ASAP
Answers
Answer:
(s - 1)(s² + s + 1)
Step-by-step explanation:
s³ - 1 ← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
s³ - 1
= s³ - 1³
= (s - 1)(s² + s + 1)
The required factorized form of the given expression is (s - 1)(s² + s + 1).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
We have been given that the expression below as
s³ - 1
We have to determine the factor of the given expression
As per the question, we have
s³ - 1
This is a difference between cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
⇒ s³ - 1 = s³ - 1³
⇒ (s - 1)(s² + s + 1)
Thus, the required factorized form is (s - 1)(s² + s + 1).

Find the Are of the Shaded Region
Answers
= 3/4 x 22/7 x 6²
= 84.86cm²
That should be the correct answer
Hope this helps!!
Answer:
≈ 84.8 cm²
Step-by-step explanation:
The area of the shaded region is calculated as
area of circle - area of unshaded sector
area of circle = πr² = π × 6² = 36π
unshaded area = area of circle × fraction of circle
= 36π × [tex]\frac{90}{360}[/tex] = 36π × [tex]\frac{1}{4}[/tex] = 9π
area of shaded region = 36π - 9π = 27π ≈ 84.8 cm² ( nearest tenth )

6. Additional information is required on the two triangles
7. The pair of triangles are similar by SAS similarity postulate
8. Yes, by triangle proportionality theorem
9. DE = 9
Step-by-step explanation:
When two or more triangles are similar, the ratio of the corresponding sides of both triangles is constant
6. From the given figure, more information is required on the two triangles
However, whereby the side with length 10 is parallel to the corresponding side on the other triangle, then the alternate angles formed by the transversal to the two parallel lines are equal and the two triangles are similar by Angle Angle, AA, similarity postulate
7. From the given triangles, the ratio of the corresponding sides relative to the given included angles are;
18/45 and 10/25
18/45 = 2/5
10/25 = 2/5
Therefore, given that two pair of corresponding sides have the same included angle and that the two included corresponding sides of the of the two triangles are proportional, then the two triangles are similar by the Side Angle Side SAS similarity postulate
8. By triangle proportionality theorem, we have;
If [tex]\overline{MN}[/tex] ║ [tex]\overline{KL}[/tex], then we have;
3/6 = 4/8 = 2
∴ [tex]\overline{MN}[/tex] ║ [tex]\overline{KL}[/tex]
9. By triangle proportionality theorem, where [tex]\overline{BE}[/tex] ║ [tex]\overline{CD}[/tex], we have;
12/20 = DE/15
∴ DE = 15 × 12/20 = 9
DE = 9

To find: distance between points [tex](-5,9),\,(4,9)[/tex]
Solution:
According to the distance formula,
Distance between points [tex](a,b)[/tex] and [tex](c,d)[/tex] is equal to [tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]
Take [tex](a,b)=(-5,9),\,(c,d)=(4,9)[/tex]

Answers
Answer:
Number of population between 16 and 60 =17,604
Step-by-step explanation:
population of town = 32600
Percentage of people over 60 years old=27%
Percentage of people 16 or under =19%
Percentage of people between 16 and 60= 100%-(27% +19%)
100-(46) =54%
Number of population between 16 and 60 =Percentage of people between 16 and 60 x population of town
=54% x 32600

Answers
Answer:
48 feets
Step-by-step explanation:
Given that:
Maggie descends 14 feets in 2 1/3 minutes
14 feets takes 7/3 minutes
The amount of feets she descends after 8 minutes will be x ;
14 = 7/3
x = 8
Cross multiply
7/3 * x = 14 * 8
7x /3 = 112
7x = 112 * 3
7x = 336
x = 336 / 7
x = 48 feets
