Answer:

y = -4

x = 3

Step-by-step explanation:

Let's first explain when x = 0

Find where x = 0 on the graph. We are finding what the y-value would be. Trace down the y-axis along the vertical line x = 0. Where does the line intersect the y-axis when x = 0? The answer would be -4

The y-intercept is -4, and the x-value for this is 0, of course. So the correct answer for when x = 0 would be y = -4.

Next, we are told to find x when y = -2. Find where y = -2. Now, staying at y = -2, go horizontally along the x-axis at y = -2 until you reach the line. Boom! You should have connected up with the line at around x = 3. Therefore, when y = -2, x = 3

So the scale is 3/4 cm for every 6 meters

So if you have 8 cm, we want to find the dimension of the actual wall

convert cm to meters

0.75 cm = 0.0075 meters

8 cm = 0.08 meters

\frac{0.0075}{6} = \frac{0.08}{x}

Cross Multiply

0.0075x = 0.48

x = 64 meters

Consider a water pipe that branches into two smaller pipes. If the flow of water is 10 L/min in the main pipe and 4 L/min in one
masha68 [24]

The water flows 6 liters per minute in the other branch of pipe.

Step-by-step explanation:

Given,

Flow of water in main pipe = 10L/min

Flow of water in one branch = 4L/min

Flow of water in other branch = x

Flow of water in main pipe = Flow in one branch + Flow in other branch

10=4+x\\10-4=x\\6=x\\x=6

The water flows 6 liters per minute in the other branch of pipe.

Dmitrij [34]

Answer:

a. Mean = 155.1 grams

b. Standard deviation = 0.37

c. Fractional uncertainty = 0.074

Step-by-step explanation:

a. Average weight

This is same as the mean weight;

Mathematically, that would be; sum of the weights/ the number of weights

= (155.1 + 154.8 + 155.5 + 155.3 + 154.6)/5 = 775.3/5 = 155.06 which is approximately 155.1

b. Standard deviation

Mathematically; we calculate that using the formula;

√{(x-mean)^2/(N-1)}

Please check attachment for for the complete breakdown of this

c. Fractional uncertainty

= Standard deviation/number of measurements = 0.37/5 = 0.074
