2. The number of nickels that Christine has is

Mathematics
1 answer:
aev [14]3 years ago
7 0

Answer:

The number of nickels is  15

The number of Dimes is 3

Step-by-step explanation:

Let the number of dimes  Christine has be d

The number of nickels with christine be n

Then the number of Nickels  Christine has will be  

n = 5d ----------------------------------(1)

Now The total value of both dimes and nickels is  = $1.05

This can be represented as

5n +10d = 105  (in cents)

From eq(1)

5(5d) + 10d = 105

25d+10d = 105

35d = 105

d = \frac{105}{35}

d = 3----------------------------------(2)

Substituting (2) in (1), we get

n = 5(3)

n = 15

Jobisdone [24]

Answer:

no soution

Step-by-step explanation:

3x - 2x + 4 = 5x - 4x - 8

Combine like terms

x+4 = x-8

Subtract x from each side

x+4-x =x-x-8

4 = -8

This is never true so there is no solution

Why do we square the residuals when using the least-squares line method to find the line of best fit?
Mekhanik [1.2K]

We square the residuals when using the least-squares line method to find the line of best fit because we believe that huge negative residuals (i.e., points well below the line) are just as harmful as large positive residuals (i.e., points that are high above the line).

<h3>What do you mean by Residuals?</h3>

We treat both positive and negative disparities equally by squaring the residual values.  We cannot discover a single straight line that concurrently minimizes all residuals. The average (squared) residual value is instead minimized.

We might also take the absolute values of the residuals rather than squaring them. Positive disparities are viewed as just as harmful as negative ones under both strategies.
