2. The mean weight of the students on the
Trail Middle School wrestling team is 150
pounds with a mean absolute deviation of
10 pounds. The mean weight of the
students on the Burlington Middle School
wrestling team is 130 pounds with a mean
absolute deviation of 10 pounds. By how
many pounds is the mean weight of the
students on Trail's team greater than the
mean weight of the students on
Burlington's team?
Answer:
The mean of Trail Middle School wrestling team is greater by 20 pounds as compared to that of Burlington Middle School wrestling team
Step-by-step explanation:
Since the value of absolute deviation in case of Trail Middle School wrestling team and Burlington Middle School wrestling team is same. Hence, there will be no impact of it while determining the difference in mean deviation of both the team.
Thus, the difference in mean deviation is [tex]150-130 = 20[/tex]
The mean of Trail Middle School wrestling team is greater by 20 pounds as compared to that of Burlington Middle School wrestling team

Answer:
ur steps would be 9*1*9 = 9^3
Step-by-step explanation:
Any number in the power of 0 = 1
Answer:
9^4
Step-by-step explanation:
Let's review the equation:
9 · 9^0 · 9^3
Anything to the power of 0 is equal to one, so 9^0 is one
That leaves us with 9 · 1 · 9^3
9 · 1 = 9
9^1 · 9^3 = 9^4
so..
9 · 9^3
How many pieces of wire 3.6cm long can be cut from a coil of 1m long?What is the length of the piece left over?
Answer:
We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over
Step-by-step explanation:
Find the "unit length" by dividing 1 m by 3.6 cm:
1 m
-----------
3.6 cm
Recall that 1 m = 100 cm. Multiply the following by the conversion factor 100 cm / 1 m:
1 m 100 cm
----------- * ----------------- = 27,7777777...
3.6 cm 1 m
We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over (verify this by dividing 7 by 9 on a calculator).
Answer:
Solution :-Pieces can be cut = 1/3.6
Pieces can be cut = 0.27 m
100 cm = 1 m
0.27 m = 27 cm
Therefore,
The length remaining of wire is 27 cm (approximately)

Step-by-step explanation:
Latasha explores some passages in a cave. The elevations of the passages are all above - 10 meters. Let y be the elevation of a passage in meters. Write an inequality that represents elevations above -10 meters.
Answer:
It is y>-10
Step-by-step explanation:
i did it and i got it right.
The inequality that represents elevations above -10 meters is y > -10.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
The inequality y > -10 means that the elevation y of a passage is greater than -10 meters.
This represents all the elevations of passages that are above -10 meters, which is the given condition in the problem.
If the elevation is exactly -10 meters or below, then it does not meet the condition of being above -10 meters.
Therefore, any elevation that is greater than -10 meters satisfies this inequality, and any elevation that is less than or equal to -10 meters does not.
Thus,
The inequality that represents elevations above -10 meters is y > -10.

Answer:
Step-by-step explanation:
Using the exponential growth function for the U. S. population from 1970 through 2003:
A = 205.1e^0.011t
with the U.S. population being 205.1 million in 1970, when would the U. S. population reach 350 million?
A.
2028
B.
2048
C.
2018
D.
2038
We have the expression
A = 205.1e^0.011t
We are asked to find when would the U. S. population reach 350 million
A = 350
350 = 205.1e^0.011t
We divide both sides by 205.1
Divide both sides by 205.1
350/205.1 = 205.1e^0.011t/205.1
1.7064846416 = e^0.011t
We take the log of both sides
log 1.7064846416 = log e^0.011t
log 1.7064846416 = t log 0.011
t = log 1.7064846416/ log 0.011
t = 0.1185057826

Cuboid ABCDEFGH is shown
BC=6.8
DE=9.3
Find the size of the angle between CF and the Plane ABCD
NEEDS ASAP WILL MARK AS BRAINLIEST IF CORRECT
Answer:
The angle formed between CF and the plane ABCD is approximately 47.14°
Step-by-step explanation:
The given parameters are;
BC = 6.8
DE = 9.3
∠BAC = 52°
We note that the angles formed by the vertex of a cuboid are right triangles, therefore, by trigonometric ratios, we get;
sin∠BAC = BC/(The length of a line drawn from A to C)
∴ The length of the line drawn from A to C = BC/sin∠BAC
The length of the line drawn from A to C = 6.8/sin(52°) ≈ 8.63
∴ AC = 8.63
By trigonometry, we have;
The angle formed between CF and the plane ABCD = Angle ∠ACF
[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]
[tex]tan\angle ACF = \dfrac{FA}{AC}[/tex]
In a cuboid, FA = BG = CH = DE = 9.3
[tex]\therefore tan\angle ACF = \dfrac{9.3}{8.63}[/tex]
[tex]\therefore \angle ACF = arctan \left(\dfrac{9.3}{8.63} \right) \approx 47.14^{\circ}[/tex]
The angle formed between CF and the plane ABCD = Angle ∠ACF ≈ 47.14°
Will mark branliest. What can the maximum number of digits be in the repeating block of digits in the decimal expansion of 1/17?
Answer:
Step-by-step explanation:
Let n=2α⋅5β⋅m , where gcd(m,10)=1 . Then, the decimal expansion of 1n is of the form
0.a1…akak+1…ak+ℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(1) ,
where k=max{α,β} and ℓ is the least positive integer for which m∣(10ℓ−1) . In other words, ℓ is the order of 10 in the multiplicative group of units modulo m . So ℓ∣ϕ(m) by Lagrange's theorem.
In particular, if gcd(n,10)=1 , then α=β=k=0 , m=n , and
1n=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(2)
Therefore, we know that
117=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(3)
Here ℓ is the least positive integer for which 17 divides 9…9ℓtimes , and we know that ℓ divides ϕ(17)=16 .
Successively squaring 10 modulo 17 gives
102≡−2(mod17),104≡4(mod17),108≡−1(mod17),1016≡1(mod17) .
So ℓ=16 in expansion (3) .
In fact,
a1…a16×17=1016–1.
a1…a8+a9…a16=108−1 .
The first fact has nothing to do with the denominator n being prime. The second fact has everything to do with n being prime, and was discovered by E. Midy in 1836 .
