Answer:

Step-by-step explanation:

Subtraction is not commutative. For example, 4 − 7 does not have the same difference as 7 − 4. The − sign here means subtraction.

However, recall that 4 − 7 can be rewritten as 4 + (−7), since subtracting a number is the same as adding its opposite. Applying the commutative property for addition here, you can say that 4 + (−7) is the same as (−7) + 4. Notice how this expression is very different than 7 – 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.

d = 16.76 inches

Step-by-step explanation:

We can extend the definition of the Pythagorean theorem to 3-dimensions:

$d = \sqrt{ {x}^{2} + {y}^{2} + {z}^{2} }$

Let x = 10 in

y = 10 in

z = 9 in

$d = \sqrt{ {(10)}^{2} + {(10)}^{2} + {(9)}^{2} }$

$d = \sqrt{281} = 16.76 \: in$

Carla is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability that

Contact [7]

Answer:

7/80

Step-by-step explanation:

(3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles

P ( green or yellow ) = number of green or yellow / total

= (3+4)/20 = 7/20

Replace

so we have (3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles

P (blue) = number of blue/ total

= 5/20 = 1/4

P ( green or yellow, replace, blue) = 7/20 * 1/4 = 7/80
