Answer: The temperature on the 5th day is -14 degrees.
Step-by-step explanation:
If we have a set of N values:
{x₁, x₂, x₃, ..., xₙ}
The mean value of this set is:
M = (x₁ + x₂ + ... + xₙ)/N
Now, we know that the mean temperature for the first 4 days of January is -4°
Then if the temperatures for the first four days are {T₁, T₂, T₃, T₄}
We have:
M₄ = (T₁ + T₂ + T₃ + T₄)/4 = -4°
Where we can replace (T₁ + T₂ + T₃ + T₄) by K
Then:
K/4 = -4°
K = -4°*4 = -16°
Is the sum of the temperatures for the first four days.
Now when we consider the first 5 days, the mean is -6°, and let's define T₅ as the temperature of the fifth day, then we get:
M₅ = -6° = (T₁ + T₂ + T₃ + T₄ + T₅)/5
And we know that:
(T₁ + T₂ + T₃ + T₄) = K = -16°
We can replace that in the above equation to get:
M₅ = (-16° + T₅)/5 = -6°
Now we can solve this for T₅
(-16° + T₅) = 5*(-6°) = -30°
T₅ = -30° + 16° = -14°
T₅ = -14°
The temperature on the 5th day is -14 degrees.

Ross bought a TV for $1,200. She sold it with 25% loss. How much did she lose?
Step-by-step explanation:
loss % = 25%
loss = $1200 × 25 ÷100
= $30000 ÷100
= $300
selling price = cost price + loss
= $1200 + $300
= $1500

Can you please tell us the question?
Step-by-step explanation:
In △ABC, G is the centroid and BE = 21. Find BG and GE.
Answer:
BG = 7, GE = 14Step-by-step explanation:
The centroid is the intercession of medians.
The centroid theorem states that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.
BE is the median and point G is 2/3 of the distance from E:
GE = 2/3BE = 2/3(21) = 14Then BG is:
BG = BE - GE = 21 - 14 = 7The answer is BG = 7, GE = 14
Answer:
the answer is BG=7,GE=14

Round 1.823 to the nearest whole number.
Answer:
2
Step-by-step explanation:
Look at the ones place (1). Look to the right of it (8). Since 8 is more than 4, raise the 1 to the next number, 2. So rounded to the nearest whole number, the decimal 1.823 is 2.

Leah is financing $340,000 to purchase a house. How much money will she save over the life of a 30-year, fixed-rate loan by buying 3 points with a rate of 6.475% instead of not buying points with a rate of 6.85%?
Answer:
$38250
Step-by-step explanation:
Given data
P= $340,000
t= 30-year,
r1= 6.475%
r2= 6.85%
For r1
A= P(1+rt)
A= 340,000(1+0.06475*30)
A= 340,000(1+1.9425)
A= 340,000*2.9425
A= $1000450
For r2
A= P(1+rt)
A= 340,000(1+0.0685*30)
A= 340,000(1+2.055)
A= 340,000*3.055
A= $1038700
The difference is '
= 1038700-1000450
=$38250

Why does stock have more potential for higher returns than bonds?
Answer:
Stocks have historically delivered higher returns than bonds because there is a greater risk that, if the company fails, all of the stockholders' investment will be lost.
Step-by-step explanation:
Hope this will help
Answer:
Stocks have historically delivered higher returns than bonds because there is a greater risk that, if the company fails, all of the stockholders' investments will be lost. However, a stock's price will also rise in spite of this risk when the company performs well, and can even work in the investor's favor.
