Is it true 4 and -4 have a sum of 0

mafiozo [28]

Answer:

Yes, 4 + -4 = 0.

Think of it like a number line: The number four is 4 units to the right of the center which is 0, and the number negative four is 4 units to the left of the center. When you add them together, those distances cancel out, and you just get 0.

Answer: Value of x is, 8

Step-by-step explanation:

Given: ,.....[1]

To find the value of x:

Using exponent rules:

Taking square both sides in [1] we have;

Simplify:

or

Multiply both sides by we get;

Answer:

The correct answer is: {2,4,6,8}

Step-by-step explanation:

Given sets are:

P = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and V= {2, 4, 6, 8, 10, 12, 14, 16, 18, 20)

We have to find

P∩V

The symbol is used for intersection of two sets. In intersection, only common elements of both sets are written in result.

So,

P∩V = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9) ∩ {2, 4, 6, 8, 10, 12, 14, 16, 18, 20)

P∩V = {2,4,6,8}

Hence,

The correct answer is: {2,4,6,8}

An e-commerce research company claims that 60% or more graduate students have bought merchandise on-line at their site. A consum

Rasek [7]

Answer:

We accept H₀ we don´t have enough evidence to conclude that a consumer group position is correct

Step-by-step explanation:

We have a case of test of proportion, as a consumer group is suspicious of the claim and think the proportion is lower we must develop a one tail test (left tail) Then

1.- Test hypothesis:

Null hypothesis H₀ P = P₀

Alternative hypothesis Hₐ P < P₀

2.- At significance level of α = 0,05 Critical value

z(c) = -1,64

3.-We compute z(s) value as:

z(s) = ( P - P₀ )/ √P*Q/n where P = 44/80 P = 0,55 and Q = 0,45

P₀ = 0,6 and n = 80

Plugging all these values in the equation we get:

z(s) = ( 0,55 - 0,6 ) / √(0,2475/80)

z(s) = - 0,05/ √0,0031

z(s) = - 0,05/0,056

z(s) = - 0,8928

4.-We compare z(s) and z(c)

z(s) > z(c) -0,8928 on the left side it means that z(s) is in the acceptance region so we accept H₀
