Mathematics
1 answer:
Neporo4naja [7]2 years ago
8 0

Answer:

40

Step-by-step explanation:

First, we must know that ab is the same as:

a × b

Now, since a is given as 8, we can substitute a with 8. This is shown below:

ab = 8 × b

Similarly, b is given as 5. So, we can substitute b with 5:

ab = 8 × 5

With this, we can now evaluate ab as shown below:

ab = 8 × 5

= 40

A least squares regression line was calculated to relate the length​ (cm) of newborn boys to their weight in kg. The relationshi
maks197457 [2]

Answer:

58.6% of the variation in length (in cm) of new born boys and their weight (in kg) is explained by the line of best fit.

Step-by-step explanation:

Given the following :

R² value = 58.6% comparing the length (cm) of new born boys to their weight (kg)

The R² value is called the Coefficient of determination. It is obtained by taking the square of the correlation Coefficient (R). The value gives the proportion of Variation between the independent and dependent variables which is explained by regression line. In the scenario above, the R² value means that 58.6% of the variation in length in centimeter of new born boys and their weight (in kg) is explained by the line of best fit. While (100% - 58.6% = 41.4%) is due to other factors.

Vedmedyk [2.9K]

Answer:

5

Step-by-step explanation:

The easiest way to do this is to add the new members to the old and then divide by 11. Ignore the remainder.

13 + 52 = 65

65 / 11 = 5 with 10 left over. Ignore the 10. That's not a complete team.

The answer is 5
