What is the y-intercept of the line with the equation 4x + 2y=12

malfutka [58]

The y-intercept (0,6) all you have to do when the formula is written like that just divide the opposite side by the number next to y.

I’m so confused. Need the help

1.621 kN

Step-by-step explanation:

Let the centerline of the canal be the x-axis. Because the forces exerted by the horses are symmetric to the centerline, only the x-components of these forces contribute to the resultant force on the barge, i.e., the y-components cancel out. Each x-component is equal to $F_x = 839\cos 15$ = 810.4 N. Therefore, the resultant force on the barge is twice this:

$F_{net} = 2(839\:\text{N})\cos 15 = 1620.8\:\text{N}$

$= 1.621\:\text{kN}$

3. Make a class frequency table using 2 rule of the following data. Find the Mean and make a Cumulative frequency Histogram [10]

sashaice [31]

Answer: Mean = 284

Step-by-step explanation:

Data:

125, 126, 127, 127, 137

201, 202, 207, 211, 215, 218, 224, 237, 261

301, 308, 310, 315, 330, 330, 360, 380, 393, 394

401, 401, 410, 421, 422, 424

Class Frequency Table:

$\boxed{\begin{array}{c|c|c}\underline{\text{Intervals}}&\underline{\text{\qquad Frequency\qquad}}&\underline{\text{Cumulative Frequency}}\\0-49&0&0\\50-99&0&0\\100-149&5&5\\150-199&0&5\\200-249&8&13\\250-299&1&14\\300-349&6&20\\350-399&4&24\\400-449&6&30\\450-499&0&30\end{array}}\\.\qquad \qquad \qquad \qquad \quad \ 30$

Mean:

The sum of the numbers divided by the quantity of numbers:

8518/30 = 283.933

Cumulative Frequency Histogram:

Create the graph based on the Interval and Cumulative Frequency of the class frequency table above. (see image)

You purchase an item to sell in your store. The item costs you $6.45. You mark the item up 20%, but later run the item on sale a

stepan [7]

So here is the answer. Given that the item originally costs $6.45 and marked it up to 20%, the new price would be $7.74, because 20% of 6.45 is 1.29. Now that it is 5% off, the new price would be $7.353. Now that it has an additional sales tax of 6%, the total amount would be $7.79 or $7.80. Hope this answers your question. Have a great day!
