If one shirt is sold for $15.50, the amount of shirts you'd be able to buy with $139.50 is 9.

Multiply 9 by 3 and you get your answer: 27 Shirts

First you take the $139.50 and divide it by $15.50

139.50 / 15.50 = 9

Then you take the 9 and multiply it by 3, be cause there are 3 shirts per $15.50

9 x 3 = 27

You can buy a total of 27 shirts with $139.50

Luda [366]

Answer:

The value of the parameter is λ is 0.03553357

Step-by-step explanation:

Consider the provided function.

$f(x) = 0.5\lambda e^{-\lambda |x|}$ for −∞ < x < ∞.

It is given that standard deviation is given as 39.8 km.

Now we need to calculate the value of parameter λ.

The general formula for the probability density function of the double exponential distribution is: $f(x)=\frac{e^{-|\frac{x-\mu}{\beta}|}}{2\beta}$

Where μ is the location parameter and β is the scale parameter.

Compare the provided equation with the above formula we get.

$\lambda=\frac{1}{\beta}$ and μ = 0.

Standard deviation = √2β

$S.D=\sqrt{2} \beta\\\beta=\frac{39.8}{\sqrt{2}}\\\beta=28.1424$

Now substitute the value of β in $\lambda=\frac{1}{\beta}$ .

$\lambda=\frac{1}{28.1424}=0.03553357$

Hence, the value of the parameter is λ is 0.03553357

Solve the system using elimination. x + 2y = –6 3x + 8y = –20 (–4, –1) (–4, 4) (–1, –4) (3, 1)

Orlov [11]

$x + 2y = - 6 > > > 3x = - 18 - 6y$
$- 18 - 6y + 8y = - 20 > > > 2y = - 2 > > y = - 1$
so x=4

What property describes the number sentence 6+0 = 6

zmey [24]

That is the Identity Property of Addition.
If it is adding and the whole number stays the same it is Identity Property of Addition.
If it is multiplying then it would be the Identity Property of Multipulcation. For example for this problem it would be 6x1 in multipulcation in which the whole number would stay the same.
Here are descriptions of all the properties:

Shelby mixes a 25% bleach solution with 5 cups of a 10% bleach solution, resulting in a 20% bleach solution. The table shows the

Tcecarenko [31]

Answer:

The value of x is 10

Step-by-step explanation:

We can use a system of equations to solve this.

Cups of 25% bleach solution used = x

Cups of 1-% bleach solution used = 5

Cups of solution we get = y

The first equation becomes:

x + 5 = y

Using the decimal forms of each percentage solution

25% solution for x cups = 0.25x

10% solution for 5 cups = 0.1(5)

20% solution for y cups = 0.2 y

The second equation becomes:

0.25x + 0.1(5) = 0.2y

So the system of equations is:

x + 5 = y

0.25x + 0.1(5) = 0.2y

Solve both equations simultaneously to find the values of x and y:

x = 10 cups

y = 15 cups

Fuji apples cost $3.00 per pound, and Golden Delicious apples cost $2.00 per pound. A childcare center purchases 30 pounds of a

konstantin123 [22]

Answer:

$3(30-g)$

Step-by-step explanation:

A following table titled Apples showing Pounds, Cost per Pound and Total.

$\begin{array}{cccc}\text{Apples}&\text{Pounds}&\text{Cost per Pound}&\text{Total}\\ \\\text{Fuji}&30-g&3&x\\ \\\text{Golden delicious}&g&2&\\ \\\text{Total}&30&&80\end{array}$

This means that

1 pound of Fuji apples costs $3

(30 - g) pounds of Fuji apples cost $\$(30-g)\cdot 3$

Hence, the total is

$x=3(30-g)$
