Mathematics

aleksklad [387]3 years ago
8 0

Answer:

The GCF of 48 and 64 is 16

Step-by-step explanation:

To figure out GCF, you make a list of all the prime factors, pick out the numbers they have in common, and multiply them together.  In this case:

48:  2 x 2 x 2 x 2 x 3

64: 2 x 2 x 2 x 2 x 2 x 2

They have four 2's in common, so you multiply 2 x 2 x 2 x 2 =16

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.

The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?
xeze [42]

Answer:

222 boys

Step-by-step explanation:

Let x = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.

\frac{5}{6+5}x = 185 (number of girls in ninth grade)

\frac{5}{11}x = 185

x=407

To find for the number of boys, we can use substitution:

\frac{6}{6+5}x = \frac{6}{11}(407)

=222

∴ There are 222 boys in the class.

Hope this helps :)
