Answer:

Felipe's expression using the Distributive Property can be written as

5 × 28 = 5( 20 + 8)

5 × 28 = (5 × 20) + (5 × 8)

Step-by-step explanation:

Distributive property states that:

a( b + c) = ab + ac

We are told in the question that:

DVDs are on sale for $28 each. Felipe writes the expression 5 × 28 to find the cost in dollars of buying 5 DVDs.

Therefore:

Felipe's expression using the Distributive Property can be written as:

5 × 28 = 5( 20 + 8)

5 × 28 = (5 × 20) + (5 × 8)

A fast food restaurant sells burgers, chicken sandwiches, and entree salads. If a customer buys a burger, the probability they b

UNO [17]

Answer:

52%

Step-by-step explanation:

We are told that, of all customers 65% buy a burger. This would imply that the proportion of customers who buy a burger is 0.65.

Moreover, if a customer buys a burger, the probability they buy french fries is 0.80. This implies that the proportion of customers who buy fries given that they bought a burger is 0.8.

Therefore, the proportion of customers who get a burger and fries is simply the product of the two probabilities;

= 0.65*0.8

= 0.52

Therefore, 52% of all customers get a burger and fries

REALLY NEED HELP!!!<br> see picture*****

vladimir1956 [14]

Answer:

11) $r=4$

12) $z_3+z_1=A$

13a) $\bar z_1=3-2i$ and $\bar z_2=-5+3i$

13b) $\bar {z_1z_2}=-9-19i$

Step-by-step explanation:

11. The given equation in rectangular coordinates is $x^2+y^2=16$

To convert to polar form, use the relation $x^2+y^2=r^2$

This implies that:

$\implies r^2=16$

$r=\sqrt{16}$

$r=4$

In polar coordinates, $r=4$ is a circle with radius 4 units.

12. From the diagram;

$z_3=-3-3i$

$z_2=1+i$

$z_1=4+i$

$A=1-2i$

We can see that two arrows are moving in anticlockwise direction to meet A which is moving in the clockwise direction;

$\implies (-3-3i)+(4+i)=1-2i$

$\therefore z_3+z_1=A$

13. The conjugate of the complex number: $z=a+bi$ is $\bar z=a-bi$

Part a) The given complex numbers are:

$z_1=3+2i$ and $z_2=-5-3i$

The conjugates of these complex numbers are:

$\bar z_1=3-2i$ and $\bar z_2=-5+3i$

Part b) The product of $z_1=3+2i$ and $z_2=-5-3i$ is

$z_1z_2=(3+2i)(-5-3i)$

$z_1z_2=-15-9i-10i-6i^2$

$z_1z_2=-9-19i$

The conjugate of the product is:

$\bar {z_1z_2}=-9-19i$
