Viktor [21]

1/4 cups = 1lb mince divide both by three
1/12 cups = 1/3lb hamburgers

1 1/3 cups = 12/12 cups + 4/12 cups
= 16/12 cups
=16 * 1/3lb hamburgers

- as 1/12 cups = 1/3lb burger, 16/12 cups = 16/3 lb burgers

How do you solve 3 = x + 3 + 6x?

joja [24]

Answer:

x=0

Step-by-step explanation:

3 = x + 3 + 6x

Combine like terms

3=7x + 3

Use order of operations to isolate x

3=7x + 3

-3 -3

0/7=7x/7

x=0/7 or 0

The Yu family and the Sainz family went on vacation together and each family leased a car. The leasing company charged a flat re

dangina [55]

Answer:

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Step-by-step explanation:

Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.

Let flat rental fee be c and cost per mile driven = m and miles driven = x

Total cost =y

Then y = mx+C is the linear equation.

to find m and c, we use the fact that y =110.30 when x = 222

i.e. 110.30 = c+222x

and similarly 99.05 = c+147x

Subtract to eliminate c

11.25 = 75 x

0.15 =x

Substitute in I equation

110.30 = c+222(0.15)

c = 77

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

The number of people in a car that crosses a certain bridge is represented by the random variable X, which has a mean value <img

nexus9112 [7]

Answer:

$E(Y) = 3 + 0.5 *2.7 = 3+1.35 = 4.35$

$Var (Y) = 0.5^2 Var (X) = 0.25 *(1.2) = 0.3$

And then we have the following parameters for the random variable Y

$\mu_Y = 4.35 , \sigma^2_Y = 0.3$

And the best option is:e. mean = $4.35, variance = $ .30.

Step-by-step explanation:

For this case we know the following info " The toll on the bridge is $3.00 per car plus $ .50 per person in the car"

So then we can create the following linear function:

$Y = 3 + 0.5 X$

Where Y represent the total amount of money that is collected from a car. And X represent the number of people in the car.

We have the parameters for the random variable X given by:

$E(X) = \mu_X = 2.7 , \sigma^2_x = 1.2$

So then we can find the expected value for the random variable Y like this:

$E(Y) = 3 + 0.5 E(X)$

And if we replace the expected value for X we got this:

$E(Y) = 3 + 0.5 *2.7 = 3+1.35 = 4.35$

Now we can find the variance for the random variable Y like this:

$Var (Y) = Var (3) + 0.5^2 Var(X) + 2 Cov(3, 0.5X)$

We know that for a number we don't have variance since is a constant and the covariance between a number and a random variable is 0 so then we have just this for the variance of Y:

$Var (Y) = 0.5^2 Var (X) = 0.25 *(1.2) = 0.3$

And then we have the following parameters for the random variable Y

$\mu_Y = 4.35 , \sigma^2_Y = 0.3$

And the best option is:e. mean = $4.35, variance = $ .30.
