y= mx + b

1) line 1.

b= 1, m=1/7, y= 2/7x +1

Colored under this line, and line is solid, so y≤ 2/7x +1.

We can modify it

7* y≤ 7*(2/7x +1), ---> 7y≤ 2x +7 or 7y-7≤2x

We have this inequality in A. and D.

2) line 2. Lets take dotted line.

y = mx + b

b= -5, m = 8/2 = 4

y = 4x -5

Colored over this line, so it is y > 4x -5. or y+5>4x

y+5>4x Between A and D we have this inequality in D.

So, we can check D.

Answer is D, if we look at the graph.

Answer:

Step-by-step explanation:

To solve problems like this, always recall the "Two-Tangent theorem", which states that two tangents of a circle are congruent if they meet at an external point outside the circle.

The perimeter of the given triangle = IK + KM + MI

IK = IJ + JK = 13

KM = KL + LM = ?

MI = MN + NI ?

Let's find the length of each tangents.

NI = IJ = 5 (tangents from external point I)

JK = IK - IJ = 13 - 5 = 8

JK = KL = 8 (Tangents from external point K)

LM = MN = 14 (Tangents from external point M)

Thus,

IK = IJ + JK = 5 + 8 = 13

KM = KL + LM = 8 + 14 = 22

MI = MN + NI = 14 + 5 = 19

Perimeter = IK + KM + MI = 13 + 22 + 19 = 54

A game of chance involves rolling an unevenly balanced 4-sided die. The probability that a roll comes up 1 is 0.21, the probabil

WITCHER [35]

Answer:

2.65 dollars

Step-by-step explanation:

The expected value for a discrete variable is calculated as:

E(x)=x1P(x1) + x2P(x2) + ... + xnP(xn)

Where x1, x2, ... , xn are the possibles values of the variable and P(x1), P(x2), ... , P(xn) are the probabilities of x1, x2, ... , xn respectively.

In this case, the roll can comes up 1, 2, 3 or 4 and you can win 1, 2, 3 or 4 dollars respectively. So, taking into account that they are mutually exclusive events, the probability that the player win 1, 2, 3 or 4 dollars is:

P(1) = 0.21

P(2) = P(1∪2) - P(1) = 0.42 - 0.21 = 0.21

P(3) = P(2∪3) - P(2) = 0.51 - 0.21 = 0.3

P(4) = 1 - P(1) - P(2) - P(3) = 1 - 0.21 - 0.21 - 0.3 = 0.28

Therefore, If you win the amount that appears on the die the expected winning are:

E(x) = $1P(1) + $2P(2) + $3P(3) + $4P(4)

E(x) = $1(0.21) + $2(0.21) + $3(0.3) + $4(0.28)

E(x) = $2.65

Suppose that a population grows according to a logistic model with carrying capacity 6000 and k=0.0015 per year.. Write a logist

makvit [3.9K]

♥ thus y’/(yf-y) = k, where yf=6000;
♠ hence ln(yf-y) =-kx +C; 
at x=0 y(0)=y0=1000, hence C= ln(yf-y0); 
and we get: 
ln((yf-y)/(yf-y0) =-kx; or; 
yf-y =(yf-y0)*exp(-kx); at last 
♦ y = 6000- 5100*exp(-0.0015*x);

dydt∝y=kyseparate the variablesdyy=kdtintegrate both sides:lny=kt+Cy(t)=Cektby plugging in t=0 we find that C the original populationy(0)=Ce0=C⟹C=y0so we gety=y0ekt
