Answer:
Alonzo ate 1/2 more than Mitra.
Step-by-step explanation:
In this question, you are supposed to find how much more Alonzo ate. We solve that like this:
Steps:
- Set up the Equation:
- 1/4 + ? = 3/4
- The question mark represents the answer.
- Inverse Operations:
- Change 1/4 + ? = 3/4 to 3/4 - 1/4 = ?
- Since Subtraction is the opposite of Addition, we flip the equation.
- Solve:
- \(\frac{3}4} -\frac{1}{4} =\frac{2}{4}\)
- Then Simplify:
- \(\frac{2}{4} =\frac{1}{2}\)
So, Alonzo ate 1/2 more than Mitra, or C.
Hope this helps! Good luck!

Why should the sum of the probabilities in a probability distribution always equal to 1?
Answer:
If u add probabilities of all possible outcomes that should be one, because classical definition of probability is number of possible out comes divided by total number of outcomes. When you add all probabilities numerator and denominator are equal so answer is one.
Answer:
The total probability of a set of related events sums up to 1 because the probability of each individual event in the set is a fraction of the whole. For example, suppose you flip a fair coin a large number of times.

Solution:
As we know she earns 0.75$ per set she sells in her website
and she sold 8 sets
hence total money he could earned = 8*0.75 = $6
but she made only = 2.25$ because remaining money she paid as website fee which was 6 - 2.25 = 3.75$
hence each week she has to pay 3.75$ as website fee so we can calculate his profit equation as follows

The polynomials ax³ -3 x² +4 and 2x³ -5x+a, when divided by (x-2), leave the remainders p and q are respectively. If p -2 q=4, find the value of a.
Given:
The polynomial are:
\(ax^3-3x^2+4\)
\(2x^3-5x+a\)
If the above polynomial divided by (x-2) then they leave remainder p and q respectively.
\(p-2q=4\)
To find:
The value of a.
Solution:
According to the remainder theorem, if a polynomial f(x) is divided by (x-c), then the remainder is f(c).
If the polynomial \(ax^3-3x^2+4\) is divided by (x-2), then the remainder is p. So.
\(a(2)^3-3(2)^2+4=p\)
\(8a-12+4=p\)
\(8a-8=p\)
If the polynomial \(2x^3-5x+a\) is divided by (x-2), then the remainder is q. So.
\(2(2)^3-5(2)+a=q\)
\(16-10+a=q\)
\(6+a=q\)
It is given that,
\(p-2q=4\)
\((8a-8)-2(6+a)=4\)
\(8a-8-12-2a=4\)
\(6a-20=4\)
Add 20 on both sides.
\(6a=4+20\)
\(6a=24\)
\(a=\dfrac{24}{6}\)
\(a=4\)
Therefore, the value of a is 4.

On June 10, Trudy Polanski deposited $1260 in a savings account that pays 5.5% interest compounded daily. How much interest will the money earn in 60 days?
The answer will be $32,893.43 compound interest will the money earn in 60 days.
What is compound interest?
The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.
When the amount compounds quarterly, it means that the amount compounds 2 times, n=12. We use this fact to derive the quarterly compound interest formula. Thus, the quarterly compound interest formula is:
A = P (1 + r/12)^12t
A = 1260(1+5.5/12) ^12
A = $32,893.43
Hence the interest will be $32,893.43.

What is F(-x)?
F(x)=x^3+1
Answer:
F(-x) = 0
Step-by-step explanation:
What is F(-x)?
F(-x) = F(-1)
F(x) = x³ + 1 F(-1)
F(-1) = -1³ + 1
F(-1) = -1 + 1
F(-1) = 0
So, F(-x) = 0
Answer:
f(-1) = 0
Step-by-step explanation:
Evaluating a function for f(-x) is the same as evaluating it for f(-1).
So we plug in -1 instead.
f(-1) = x³ + 1
= (-1)³ + 1 (here we cube -1)
= -1 + 1 (here we subtract)
= 0 (and, this is the answer)

2-7i over -2+5i solve
2-7i/-2+5i
The general rule of division in the complex set is,
\(\frac{a}{b}=\dfrac{a\bar{b}}{b\bar{b}}; a,b\in\mathbb{C}\).
If \(b=c+di\) than \(\bar{b}=c-di\) this is called complex conjugate of a complex number.
We have,
\(a=2-7i\)
\(b=-2+5i\)
The complex conjugate of b is \(\bar{b}=-2-5i\).
Now perform the algebra,
\(\dfrac{(2-7i)(-2-5i)}{(-2+5i)(-2-5i)}=\dfrac{-4-10i-14i+35i^2}{4+10i-10i-25i^2}\)
\(=\dfrac{-4-24i-35}{4+25}=\boxed{\dfrac{-39-24i}{29}}\)
In complex form that is,
\(-\dfrac{39}{29}-\dfrac{24}{29}i\)

3 cos x + 2
The function is f(x) = 3 sin x
3 sin x
3 cos x
2 X
The equation of the sinusoid function is:
3 Sin πx + 2.
Let's analyze the given options to find the correct equation:
a. 3 Cos πx + 2:
This option is a cosine function with a vertical shift of 2, but it does not have the correct amplitude or period. Therefore, it is not the correct equation.
b. 3 Sin x: This option is a sine function with the correct amplitude, but it does not have the correct vertical shift or period. Therefore, it is not the correct equation.
c. 3 Sin πx + 2: This option is a sine function with the correct amplitude and vertical shift. Let's check if it has the correct period:
To determine if the period is correct, we need to calculate the x-values when the function repeats itself.
In this case, we need to find x-values such that sin(πx) = 0, since the function will reach its maximum and minimum points again at those x-values.
sin(πx) = 0 when πx = 0, π, 2π, 3π, ...
Solving for x, we have:
πx = 0 ⟹ x = 0
πx = π ⟹ x = 1
πx = 2π ⟹ x = 2
πx = 3π ⟹ x = 3
From this, we can see that the function repeats itself every integer value of x, which matches the given information.
Therefore, option (c) is the correct equation: 3 Sin πx + 2.
Option (d) 3 Cos x does not have the correct vertical shift or period, so it is not the correct equation.
Hence, the equation of the sinusoid function is:
