The second choice, y+1=6/11(x+4), is correct.

We first find the slope using the formula

m=(y₂-y₁)/(x₂-x₁)

Using our points, this gives us
m=(-1-5)/(-4-7) = -6/-11 = 6/11

Point-slope form is
y-y₁=m(x-x₁)

Using the first point, we would have
y-5=6/11(x-7)

Using the second point, we would have
y--1=6/11(x--4)
y+1=6/11(x+4)

ELEN [110]

Answer:

D.

Step-by-step explanation:

Two events A and B are independent when

$P(A|B)=P(A),$

where $P(A|B)$ is the probability that event A occurs given that event B has occured.

A = randomly selected person is from California

B = randomly selected person preferred brand A

A|B = being a person from California and preferring brand A.

Hence,

$P(A)=\dfrac{150}{275}=\dfrac{6}{11}\approx 0.55\\ \\P(B)=\dfrac{176}{275}=\dfrac{16}{25}=0.64\\ \\P(A|B)=\dfrac{96}{176}=\dfrac{6}{11}\approx 0.55$

Since $P(A)=P(A|B),$ events are independent.

A 14 gram sample of a substance that's used to preserve fruit and vegetables has a k-value of 0.1092. Find the substance's half-

nignag [31]

Answer:

t = 6.3

Step-by-step explanation:

N=Noe^(-kt)

No = 14 grams

k = .1092

We want to find t when N = 7 or 1/2 of 14

N=Noe^(-kt)

7 = 14 e ^ (-.1092t)

Divide each side by 14

1/2 = e ^ (-.1092t)

take the natural log of each side

ln (1/2) = ln e ^ (-.1092t)

ln (1/2) = -.1092t

Divide each side by -.1092

ln (1/2)/ -.1092 = t

t≈6.3475

Rounding to the nearest tenth

t = 6.3

Answer:

<u>(0, - 6)</u>

Step-by-step explanation:

<u>Midpoint Formula</u>

M = (x₁ + x₂ / 2, y₁ + y₂ / 2)

<u>Solving</u>

M = (-3 + 3 / 2, -7 - 5 / 2)
M = (0, -12/2)
M = <u>(0, - 6)</u>
