Solving Proportions 19/4 = x/4

Mathematics
1 answer:
fredd [130]3 years ago
7 0

Answer:

x = 19

Step-by-step explanation:

To solve proportions, you first need to cross multiply. \frac{19}{4}= \frac{x}{4}, you would need to multiply each top number by 4. 76 = 4x, which then could easily be simplified down to 19 by just dividing by four.

The following sequence is an arithmetic sequence what comes next ? 7,___,17
ipn [44]

Since this is an arithmetic sequence, you can conclude that the addition to the number is constant.

Let x = the number asked

       k = constant number added to the sequence

7 + k = x

x + k = 17

Solve the system of equation:

7 + k + k = 17

7 + 2k = 17

2k = 10

k = 5

Therefore, the missing number is 12 (7 + 5).

maksim [4K]

The residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

<h3>What is residual value?</h3>

The residual value is the estimated value which is calculated for the end of the lease terms for a fixed asset.

Points and their residual values are shown in the table. A 3-column table with 5 rows.

  •  x                               1,     2,     3,     4,     5.
  •  y                               2,   3.5,   5,    6.1,    8.
  • Residual Value       -0.4, 0.7,  -0.2, -0.6   0

The simple regression line can be represented as,

\hat y=\alpha +\beta X+\hat e

Here α is the constant, β is the slope and <em>e </em>is the residue.

The point which is farthest from the best fit of the line is 3.5. At y=3.5, the value of residue is 0.7.

Thus, the residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.
