What expression simplifies to 2i ? help asap lots of points

PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

First, consider the following expression.

(6x + 8) + (4x + 2)

To simplify this expression, you combine the like terms, 6x and 4x. These are like terms because they have the same variable with the same exponents. Similarly, 8 and 2 are like terms because they are both constants, with no variables.

(6x + 8) + (4x + 2) = 10x + 10

Answer:

C. P- value < 0.04 0.05

Step-by-step explanation:

hello,

we were given the sample size, n = 200

also the probability that the psychic correctly identifies the symbol on the 200 card is

$p=\frac{50}{200}= 0.25$

using the large sample Z- statistic, we have

$Z=\frac{p- 0.20}{\sqrt{0.2(1-0.2)/200} }$

= $\frac{0.25-0.20}{\sqrt{0.16/200}}$

= 1.7678

thus the P - value for the hypothesis test is P(Z > 1.7678) = 0.039.

from the above, we conclude that the P- value < 0.04, 0.05
