Answer:
true
Step-by-step explanation:
first put value of x as 12 then,
2×12-5=19
24-5=19
19=19
Answer:
I believe the answer is 80 meters.
Note: I am not sure how to explain this so that it makes sense.
The slope intercept form of the line whose points are (1,5) and (-2,-4) is y=3x+2.
Given two points of a line (1,5) and (-2,-4).
We have to form an equation in slop intercept form.
Equation is relationship between two or more variables which are expressed in equal to form.Equations of two variables looks like ax+by=c.
Point slope form of an equation is y=x+mc where m is slope of the line.
From two points the formula of equation is as under:
(y-)=*(x-)
where are the points.
Putting the values of =1, =-2, =5 and =-4.
y-5=(-4-5/-2-1)*(x-1)
y-5=-9/-3*(x-1)
y-5=3(x-1)
y-5=3x-3
y=3x-3+5
y=3x+2
Hence the slope intercept form of the line having points (1,5)(-2,-4) is y=3x+2.

Answer:
The probability that X and Y are both positive and that their sum is less or equal to 1 0.64.
Step-by-step explanation:
It is provided that the random variables <em>X</em> and <em>Y </em>follows a standard normal distribution.
That is,
It is also provided that the variables <em>X</em> and <em>Y </em>are statistically independent of each other.
Compute the probability that X and Y are both positive and that their sum is less or equal to 1 as follows:
The mean and standard deviation of <em>X</em> + <em>Y</em> are:
The probability is:
*Use the <em>z</em>-table.
Thus, the probability that X and Y are both positive and that their sum is less or equal to 1 0.64.
