Answer:

The value of the equation for z is $z=\frac{bc-wx}{y}$

Step-by-step explanation:

Consider the provided information.

We need to solve the equation for z.

Solve the equation for z as shown:

$wx+yz=bc$

Subtract wx from both the sides.

$wx+yz-wx=bc-wx$

$yz=bc-wx$

Divide both the sides by y.

$z=\frac{bc-wx}{y}$

Hence, the value of the equation for z is $z=\frac{bc-wx}{y}$

Yz= bc - wx
==> z= (bc -wx) / y

A person draws a card from a hat. Each card is one color with the following probabilities of being drawn: 1/10 for red, 1/5 for

Kay [80]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

We are given that a card is drawn from a hat.

Probability that a red card is drawn, P(red) = $\frac{1}{10}$

Probability that a blue card is drawn, P(blue) = $\frac{1}{5}$

Probability that a black card is drawn, P(black) = $\frac{1}{20}$

Probability that a pink card is drawn, P(pink) = $\frac{1}{5}$

All these events are mutually exclusive i.e. they do not have anything in common.

For any two events A and B which are mutually exclusive, with probability P(A) and P(B), the probability that any one of the two events occur:

$P(A\cup B) = P(A) + P(B)$

Here event A can be thought of as drawing a blue card and

event B can be thought of as drawing a black card

So, P(blue or black) = P(blue) + P(black)

$\Rightarrow \dfrac{1}{5}+\dfrac{1}{20}\\\Rightarrow \dfrac{4+1}{20}\\\Rightarrow \dfrac{5}{20}\\\Rightarrow \dfrac{1}{4}$

So, the probability that a blue or black card is drawn from the hat:

$\dfrac{1}{4}$

Undo the subtraction of x-2=6

spayn [35]

Answer:

x = 8

Step-by-step explanation:

I am assuming that you want to solve for x.

Note the equal sign, what you do to one side, you do to the opposite side. Isolate the variable, x. Add 2 to both sides:

x - 2 (+2) = 6 (+2)

x = 6 + 2

x = 8

x = 8 is your answer.

Use piece wise function to answer f(0)=

MrMuchimi

Answer:

$f(0) = 0$

Step-by-step explanation:

Given

See attachment

Required

Determine f(0)

To solve for f(0), we make use of:

$f(t) = \frac{t^3}{t + 9}$

Because: $t \ge -2$ is true for $t =0$

So, we have:

$f(t) = \frac{t^3}{t + 9}$

$f(0) = \frac{0^3}{0 + 9}$

$f(0) = \frac{0}{9}$

$f(0) = 0$
