Find the slope of line that is parallel to -2x=3y+5

In-s [12.5K]

Answer: m = $-\frac{2}{3}$

Step-by-step explanation:

Turn the equation into slope-intercept form: $-3y = 2x + 5$

Reduce: $y = -\frac{2}{3}x -\frac{5}{3}$

Your parallel slope is: $-\frac{2}{3}$

A noted psychic was tested for extrasensory perception. The psychic was presented with 2 0 0 cards face down and asked to determ

Natasha2012 [34]

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

Whats a linear function

slega [8]

Answer:

A Linear Function is any function that graphs to any straight line. It can be consist of one or 2 or more variables but the degree or the exponent value of the variable shouldn't be greater than 1. it can be 0 but not greater than one .

Step-by-step explanation:

f(x)= y= a +bx , is the example of linear fucntion where the variable x has the exponent value of 1 ,

but the function f(x)= y= a+bx^2 is not a linear function because the exponent value of variable x is 2 .

Also if the Value of Exponent of the variable is in negative, that will be also a non linear function .
