In which graph does y vary directly as x? It’s not C, I got it wrong.

Hello there!

Based on my research and information, I really believe that (option a) would actually be your correct answer. I believe this basically because sense the letter k is always constant, we would only divide this by what it is, which is y, and from these, your solution would always look like your (option a). Please inform if correct.

Happy to help!

Sketch the graph of each line

adoni [48]

Answer:

(0,5) (1,0)

Step-by-step explanation:

Place your first dot on the 5 (0,5) of the y-axis (The one that is vertical) from there count down the line one value at a time until you have counted DOWN 5 times. Go to the right once and place another point there (1,0). Then draw a straight line that connects those two points.

Resistors are labeled 100 Ω. In fact, the actual resistances are uniformly distributed on the interval (95, 103). Find the mean

Zinaida [17]

Answer:

$E[R]$ = 99 Ω

$\sigma_R$ = 2.3094 Ω

P(98<R<102) = 0.5696

Step-by-step explanation:

The mean resistance is the average of edge values of interval.

Hence,

The mean resistance, $E[R] = \frac{a+b}{2} = \frac{95+103}{2} = \frac{198}{2}$ = 99 Ω

To find the standard deviation of resistance, we need to find variance first.

$V(R) = \frac{(b-a)^2}{12} =\frac{(103-95)^2}{12} = 5.333$

Hence,

The standard deviation of resistance, $\sigma_R = \sqrt{V(R)} = \sqrt5.333$ = 2.3094 Ω

To calculate the probability that resistance is between 98 Ω and 102 Ω, we need to find Normal Distributions.

$z_1 = \frac{102-99}{2.3094} = 1.299$

$z_2 = \frac{98-99}{2.3094} = -0.433$

From the Z-table, P(98<R<102) = 0.9032 - 0.3336 = 0.5696

The value of x is 4 times the value of y.how to writ that in math

kakasveta [241]

I’m not exactly sure what you mean by “write it in math,” however I can tell you what I think.
4y=x
(It says that x is 4 times the value of y which means that y times 4 is x.)

A computer has the shape of a rectangular solid. Find the volume of the computer, with dimensions of 3 inches by 3 inches by 3.6

Karo-lina-s [1.5K]

To find the volume of the computer, we just have to multiply each coordinate.

$\begin{gathered} V=3in\times3in\times3.6in \\ V=32.4in^3 \end{gathered}$ <h2>Hence, the volume is 32.4 cubic inches.</h2>
