Find the midpoint of the line segment whose endpoints are (0,1/2 ) and (0,3/4 ).

Answers

Formula of the midpoint:
x =(x₁+x₂)/2 and y = (y₁+y₂)/2

Plugin the respective value
for A(0,1/2) and B(0, 3/4)

x= (0+0)/2 = 0
y = (1/2 + 3/4)/2 = 5/8

Then the midpoint of the line segment whose endpoints are (0,1/2 ) and (0,3/4 ). is M(0, 5/8) or M(0, 0.625)

Answer:

(0, 5/8)

Which normal distribution has a wider spread: the one with mean 3 and standard deviation 4 or the one with mean 4 and standard deviation 3 ? the normal distribution with mean 4 and standard deviation 3 has the wider spread?

Answers

Answer:

The correct option is 1. The normal distribution with mean 3 and standard deviation 4 has a wider spread.

Step-by-step explanation:

Normal distribution is defined by two variables, mean and standard deviation.

[tex]Z=\frac{X-\mu}{\sigma}[/tex]

The spread of a normal distribution is not dependent on mean, it is completely dependent of standard deviation. Larger standard deviation means wider spread.

It is given that first normal distribution has

[tex]\mu_1=3[/tex]

[tex]\sigma_1=4[/tex]

Second normal distribution has

[tex]\mu_2=4[/tex]

[tex]\sigma_2=3[/tex]

Since [tex]\sigma_1>\sigma_2[/tex], therefore the normal distribution with mean 3 and standard deviation 4 has a wider spread.

Hence the correct option is 1.

Final answer:

The normal distribution with a mean of 3 and a standard deviation of 4 has a wider spread than a normal distribution with a mean of 4 and a standard deviation of 3, as the spread is determined by the standard deviation.

Explanation:

The question is asking which of the two normal distributions has a wider spread. The spread of a normal distribution is determined by its standard deviation. A normal distribution with a higher standard deviation will have a wider spread. In this case, the normal distribution with a mean of 3 and a standard deviation of 4 will have a wider spread compared to the normal distribution with a mean of 4 and a standard deviation of 3. Thus, the statement 'the normal distribution with mean 4 and standard deviation 3 has the wider spread' is incorrect.

In a normal distribution, as the standard deviation increases, the distribution curves become wider and shorter, reflecting a greater spread in the data. Because both distributions are normally distributed, we can compare the standard deviations directly to determine the spread: a standard deviation of 4 indicates a wider spread than a standard deviation of 3.

The sum of two complex numbers, where the real numbers do not equal zero, results in a sum of 22i. Which statement must be true about the complex numbers?

Answers

Answer: The complex numbers have opposite real numbers.

This a prove of that conclusion:

Let A + Xi be one complex number and B + Yi the other complex number, then:

A + Xi + B + Yi = 0 + 22i

=> A + B = 0 => A = -B, which means that the real part of one of the complex number is the opposite of the real part of other complex number. The imaginary part is not relevan for the question.

Answers

As it is one-to-one function, f −1(12) = 1

f-1(x) is the inverse of f(x)

The domain of f(x) = range of f(-1)x and vice-versa.

So f-1(12) = 1.

The distance between P and T on the coordinate grid is ___ units. (Input whole numbers only.) Image of a coordinate grid with point P located at negative 10, 15 and point T located at 15, 15.

Answers

That would be 25 units. You can draw it out and you would get 25 units, or you could see the difference in -10 and 15, their distance would be 25 units.

That made no sense.

Answer:

The distance between P and T on the coordinate grid is 25 units.

Step-by-step explanation:

Coordinate of P = (-10,15)

Coordinate of T = (15,15)

By distance formula we have distance between ( a,b) and (c,d) is

[tex]\sqrt{(c-a)^2)+(d-b)^2}[/tex]

Here (a,b) = Coordinate of P = (-10,15) and (c,d) = Coordinate of T = (15,15)

Substituting

[tex]\texttt{Distance =}\sqrt{(c-a)^2)+(d-b)^2}=\sqrt{(15-(-10)^2)+(15-15)^2}=\sqrt{25^2}=25units[/tex]

The distance between P and T on the coordinate grid is 25 units.

The maximum of f(x) is y = 3. This is the y coordinate of the vertex (6,3).

Note how y = -4(x-6)^2 + 3 is in the form y = a(x-h)^2 + k, which is vertex form. So we can see that the vertex is (h,k) = (6,3), since h = 6 and k = 3.

Note: This graph is an upside down parabola with (6,3) as the highest point.

---------------------------------------

In contrast, the max of g(x) is y = 6. This is the y coordinate of the highest point on the curve. One such point is (pi/2, 6). There are infinitely max points because the up and down pattern goes on forever.

So g(x) has the larger max compared to f(x).

A store is having a sale on almonds and jelly beans. For 8 pounds of almonds and 3 pounds of jelly beans, the total cost is $18 . For 2 pounds of almonds and 5 pounds of jelly beans, the total cost is $13 . Find the cost for each pound of almonds and each pound of jelly beans.

Answers

8a + 3j = 18
2a + 5j = 13....multiply by -4
--------------
8a + 3j = 18
-8a - 20j = - 52 (result of multiplying by -4)
-------------add
-17j = - 34
j = -34/-17
j = 2 <=== jelly beans cost $ 2.00 per lb

8a + 3j = 18
8a + 3(2) = 18
8a + 6 = 18
8a = 18 - 6
8a = 12
a = 12/8
a = 1.50 <=== almonds cost $ 1.50 per lb

By setting up a system of equations and solving them, we find that the cost per pound of almonds is $1.50, and the cost per pound of jelly beans is $2.00.

To find the cost for each pound of almonds and each pound of jelly beans, we can set up two equations to solve the problem algebraically. Let's denote the cost per pound of almonds as a and the cost per pound of jelly beans as b. We have two scenarios provided:

8 pounds of almonds and 3 pounds of jelly beans cost a total of $18.

2 pounds of almonds and 5 pounds of jelly beans cost a total of $13.

We can translate these scenarios into two algebraic equations:

8a + 3b = 18

2a + 5b = 13

Now, we will solve this system of equations to find the values of a and b.

Step 1: Multiply Equation (2) by 4

8a + 20b = 52 (We multiplied all terms by 4 to match the coefficient of a in Equation (1))

Step 2: Subtract Equation (1) from the new equation

8a + 20b - (8a + 3b) = 52 - 18

17b = 34

Step 3: Solve for b

b = 34 / 17

b = 2

Now we know each pound of jelly beans costs $2.

Step 4: Substitute b back into Equation (1) to solve for a

8a + 3(2) = 18

8a + 6 = 18

8a = 12

a = 12 / 8

a = 1.5

So, each pound of almonds costs $1.50.

Therefore, the cost per pound of almonds is $1.50, and the cost per pound of jelly beans is $2.00.
