Solve the equation below. Graph the solution on a number line. w/2 = -1 w =

8_murik_8 [283]

Multiply both sides by 2

w= -1×2

simplify 1×2 to 2

w= -2

Unit 2 Lesson 2:Surface Area

seropon [69]

Part 2) What is the surface area of this cube?
we know that
surface area of a cube=6*b²
where b is the length side of a cube
in this problem
b=15 mm
so
surface area of a cube=6*15²----> 1350 mm²

the answer Part 2) is 1350 mm²

Part 3) What is the surface area of this cube?
we know that
surface area of a cube=6*b²
where b is the length side of a cube
in this problem
b=11 cm
so
surface area of a cube=6*11²----> 726 cm²

the answer Part 3) is 726 cm²

part 4) What is the surface area of the rectangular prism represented by the net?

surface area=2*16*6+2*16*8+2*6*8----> 544 cm²

the answer Part 4) is 544 cm²

Part 5) What is the surface area of the wood block?
surface area=5*5+4*[5*8]/2----> 25+80----> 105 in²

the answer part 5) is 105 in²

A certain store sells only T-shirts. Let the random variable X represent the number of T-shirts bought from the store on any day

faltersainse [42]

Answer:

$(a)\ \mu_y = 1125$

$(b)\ \sigma_y = 300$

Step-by-step explanation:

Given

$\mu_x = 75$ -- Mean of T-shirts

$\sigma_x = 20$ -- Standard deviation of T-shirts

$Rate = \$ 15$

Solving (a): The mean of the revenue $(\mu_y)$

To solve this, we use:

$\mu_y = Rate * \mu_x\\$

This gives:

$\mu_y = 15 * 75$

$\mu_y = 1125$

Solving (b): The standard deviation of the revenue $(\sigma_y)$

To solve this, we use:

$\sigma_y = \sqrt{Rate^2 * \sigma_2^2}$

This gives:

$\sigma_y = \sqrt{15^2 * 20^2}$

$\sigma_y = \sqrt{90000}$

$\sigma_y = 300$

A special deck of cards has ten cards. Four are green (G), four are blue (B), and two are red (R). When a card is picked, the co

a_sh-v [17]

Answer:

{GT, GH, BT, BH, RT, RH};

1 /5;

Mutually exclusive ;

Not mutually exclusive.

Step-by-step explanation:

Given :

Green cards, G = 4

Blue cards, B = 4

Red cards, R = 2

For a coin toss :

{H, T}

A card is picked, then a coin is tossed :

Sample space :

{GT, GH, BT, BH, RT, RH}

2.) probability of picking a green card, then probability of landing a head on a coin toss

P(A) = number of required outcome / Total possible outcomes

P(A) = P(green card) * P(Head)

P(A) = (4 / 10) * (1/2)

P(A) = 4 /20

P(A) = 1/5

C.)

Both A and B are mutually exclusive, since both event A and event B cannot occur together, since both red and green cannot be picked during a single pick, this either a red is picked or green is picked, then they are A and B are mutually exclusive.

D.) Event A and C are not mutually exclusive, picking a green card, event A and picking a red or blue card, event B. Both event can happen simultaneously, hence, event A and B are not mutually exclusive.
