(8,-9) = 4\cdot \:8+5\left(-9\right)=-13\quad :\quad \mathrm{True}

(-2,-1) = 4\left(-2\right)+5\left(-1\right)=-13\quad :\quad \mathrm{True}

(6,3) = 4\cdot \:6+5\cdot \:3=-13\quad :\quad \mathrm{False}

(-7,4) = 4\left(-7\right)+5\cdot \:4=-13\quad :\quad \mathrm{False}

What transformation rule would represent a shift of 3 units to the left 4 units down?
Llana [10]

Given:

Shift of 3 units to the left 4 units down.

To find:

The transformation rule.

Solution:

The rule of transformation is

(x,y)\to (x+a,y+b)          ...(i)

Here, a<0 if the figure shifts a units left and a>0 if the figure shifts a units right.

Similarly, b<0 if the figure shifts b units down and b>0 if the figure shifts b units up.

If a transformation represents shift of 3 units to the left 4 units down, then a=-3 and b=-4.

Putting a=-3 and b=-4 (i), we get

(x,y)\to (x+(-3),y+(-4))

(x,y)\to (x-3,y-4)

Therefore, the correct option is B.

Marissa is drawing coins from a bag that contains 5 pennies (yellow), 4 nickels (green), 5 dimes
Anna007 [38]

Answer:

\frac{4}{16}=\frac{1}{4}=0.25=25\%

Step-by-step explanation:

Total number of coins in the bag = 5 + 4 + 5 + 2 = 16 coins

Number of nickels in the bag = 4

We have to find the probability that Marissa draws a nickels from the bag.

Probability is defined as the ratio of Number of "Favorable Outcomes" to "Total number of possible outcomes"

In this case total number of possible outcomes is the total number of coins which is 16.

Favorable/Desires outcome is drawing a Nickle from the bag which are 4 in number. So, number of favorable outcomes is 4

Therefore, the probability that she will draw a nickel = \frac{4}{16}=\frac{1}{4}=0.25=25\%

Daniel [21]

Answer:

The sample space

Step-by-step explanation:

By definition, the sample space is the set composed by all the possible outcomes of your random variable. In this case, the random variable is 4 sided dice, so the sample space is

\Omega=\{1,2,3,4\}
