-7(5-3x)=-35 what is the x in the problem
Irina-Kira [14]

Answer:

x = 0

Step-by-step explanation:

-7(5-3x)=-35

Divide by -7

-7/-7(5-3x)=-35/-7

5 -3x = 5

Subtract 5 from each side

5-3x-5 = 5-5

-3x=0

Divide by -3

x=0

McSaw’s Ice Cream makes muffins that cost $.60 each. Past experience shows that 10% of the muffins will become stale and have to
allochka39001 [22]
Well, due to that 10% of the muffins get wasted and do not sell,
plus work that goes into it, the price of the ice-cream is  not 0.60,
but 55% more, or markup above that cost value

so... how much would each muffin sell for? well, each muffin will be,
0.60 + 55% of 0.60

how much is 55% of 0.60?
{{ 55}}\%\ of\ 0.60 \implies  \cfrac{{{ 55}}}{100}\cdot 0.60\implies {{ 55}}\div 100\cdot 0.60

get the 55%, and add it to the 0.60, that's how much each will sell for

________ are numbers equally likely to be chosen from a large population of numbers.
ki77a [65]

A simple random sample are numbers equally likely to be chosen from a large population of numbers.

<h3>What is Population?</h3>

This is defined as the total number of people or variables present in an area over a given period of time.

Numbers are usually chosen at random from a large population for different reasons and are referred to as simple random sample because they have an equal probability of being chosen.

Find two unit vectors orthogonal to both given vectors. i j k, 4i k
Maurinko [17]
The cross product of two vectors gives a third vector \mathbf v that is orthogonal to the first two.

\mathbf v=(\vec i+\vec j+\vec k)\times(4\,\vec i+\vec k)=\begin{vmatrix}\vec i&\vec j&\vec k\\1&1&1\\4&0&1\end{vmatrix}=\vec i+3\,\vec j-4\,\vec k

Normalize this vector by dividing it by its norm:

\dfrac{\mathbf v}{\|\mathbf v\|}=\dfrac{\vec i+3\,\vec j-4\,\vec k}{\sqrt{1^2+3^2+(-4)^2}}=\dfrac1{\sqrt{26}}(\vec i+3\,\vec j-4\vec k)

To get another vector orthogonal to the first two, you can just change the sign and use -\mathbf v.
