Answer:

Step-by-step explanation:

So, if we are looking to save money, then it would probably be a good choice to go for the least steepest line. Assuming Money stands for the Y axis and Quantity stands for the X axis, then looking at the least steepest line means the lowest Y axis, which translates to the least amount of money.

Suppose that a recent poll found that 40% of adults in a certain country believe that the overall state of moral values is poor.

shusha [124]

Answer:

Step-by-step explanation:

Let X be the no of adults whose feelings the state of morals is poor.

X has two outcomes and each trial is independent of the other

X is Bin with p = probability for success in each trial =40%=0.40

n=no of adults surveyed = 55

a) The probability that exactly 21 of those surveyed feel the state of morals is poor is

$P(X=21) = 40C21 (0.4)^{21} (1-0.4)^{19} \\=0.03519$

(b) The probability that no more than 22 of those surveyed feel that state of morals is poor is

= $P(X$

$P(X>22)\\=1-0.9811\\=0.0119$

(d) The probability that 15 or 16 believe the state of morals is poor is

= $P(X=15)+P(X=16)\\=0.1228+0.1279\\=0.2507$

-2.1b +5.3= b -- 3.1b + 5.3 does is have one solution or infinitely many solutions ? Why ?

pychu [463]

Answer: infinitely many solutions.

Step-by-step explanation:

Ok, our equation is:

-2.1*b + 5.3 = b - 3.1*b + 5.3

now, simplifyng the right side, we have:

b - 3.1*b + 5.3 = (1 - 3.1)*b + 5.3 = -2.1*b + 5.3

Then our initial expression is:

-2.1*b + 5.3 = -2.1*b + 5.3

So in both sides of the equality we have the exact same thing, so this is a trivial equality.

This means that the equality will remain true for any value of b, which means that we have infinitely many solutions.

Determine the x- and y-intercepts of each line x+3y=24

ivann1987 [24]

Determine the x- and y-intercepts of each line x+3y=24
+ x=0, so y= 24:3=8 and we have y-intercepts is 8
+ y=0, so we have x=24, x-intercepts is 24
