Note: I ended up with the simultaneous equations, which are correct according to the markscheme BUT the answers I got upon solving them were incorrect.
μ = 170 + 1.6449σ
μ = 180 - 0.8416σ
What I got after solving these were:
μ = 169.5306859
σ = 12.44864932
But according to the markscheme, I should have gotten:
μ = 176.615...
σ = 4.021...
Can someone explain to me where I've gone wrong?
Answer:
Yes, your simultaneous equations are correct;
Solve them like so:
170 + 1.6449σ = 180 - 0.8416
2.4865σ = 10
σ = 4.0217...
μ = 170 + 1.6449(4.0217...)
μ = 176.615...
MS is correct, you must've made an error in solving or rearranging
Find the circumference of the object. Use 3.14 or 22 7 for ml. Diameter:9
Answer:
c = 28.26 cm
Step-by-step explanation:
equation for circumference of a circle is 2πr
r = d/2 so here r = 9/2 = 4.5
2 x 3.14 x 4.5 = 28.26
Answer:
C ≈ 28.26 cm
Step-by-step explanation:
The circumference (C) is calculated as
C = πd ( d is the diameter ) , then
C = π × 9 ≈ 3.14 × 9 = 28.26 cm ( to the nearest hundredth )

was given a discount of 36%. How much did I pay for
the camera?
Answer:
$4,608.00
Step-by-step explanation:
Subtract 36% from 7,200 and you get 4,608.
solve for x
plsss. & then solve for y
Answer:
x=22, y=35
Step-by-step explanation:
since this is an isosceles triangle, 3x-11 = 2x+11. so x=22
since this is a triangle 3x-11 + 2x+11 + 2y = 180. plug in x and simplify to get 2y+110=180, so 2y=70 and y=35

look at the right angle triangle ABC 75
Answer:
A and B are equal to 52.5°
Step-by-step explanation:
One angle has to be 75°, so let's say that angle C is 75°. You need to subtract 75 from 180, which is 105°. Now, divide 105° by 2, which equals 52.5. Your answer is: Angles A and B are both equal to 52.5

The US Constitution originally said that senators would be selected by state legislatures. Per the terms of the 17th Amendment, senators are now elected directly by the citizens of their respective states.
The party balance in the 115th Congress (2017–19) is 51 Republicans, 47 Democrats, and 2 independents, who caucus with the Democrats. As of January 2018, Republicans had control of the legislatures of 31 states; Democrats had control in 14; control was split in 4; and Nebraska was officially nonpartisan.
Develop an argument for or against repealing the 17th Amendment.
In your essay, you must:
articulate a defensible claim or thesis that responds to the prompt and establishes a line of reasoning.
use your knowledge of federalism, the constitutional position of the US Senate, partisan politics, checks and balances, voting rights, and the history of redistricting or gerr
Based on the provisions of the 17th Amendment, we can see that the provisions of the United States Constitution gave the people the right to vote for their senators who would represent their interests instead of the state legislature.
With this in mind, we can see that if the seat of a senator is unoccupied, then the governor of the state can make his appointment of a senator.
Based on the given data on the party balance of the US Senators, it is still not enough reason to repeal the 17th Amendment because giving the people the right to choose their representatives is still the core value of democracy which should never be tampered with.
