Answer:
Step-by-step explanation:
Without 1 more piece of information, we can only say that Larry exceeds Katie by 7/10 - 6/10 = 1/10 the distance closer. Add a fact, and we'll come back and modify our answers.
C. It is always a rational number. You cannot determine its sign without knowing the values of a and b.
Answer:
And for this case
The % of variation is given by the determination coefficient given by and on this case , so then the % of variation explained is 20.25%.
The proportion of the variability seen in final grade performance that can be predicted by math ability scores is 20.25%.
Step-by-step explanation:
For this case we asume that we fit a linear model:
Where y represent the final grade and x the math ability scores
Where:
And we can find the intercept using this:
The correlation coeffcient is given by:
And for this case
The % of variation is given by the determination coefficient given by and on this case , so then the % of variation explained is 20.25%.
The proportion of the variability seen in final grade performance that can be predicted by math ability scores is 20.25%.

Answer:
84cm²
Step-by-step explanation:
Perímetro de un rectángulo = 2L + 2W
Representemos la longitud del rectángulo = L
En la pregunta anterior se nos dijo que el ancho del rectángulo = es menor que 5 en la longitud
Por lo tanto, ancho del rectángulo = L - 5
Perímetro del rectángulo = 38 cm
Por lo tanto
38 = 2 (L) + 2 (L - 5)
38 = 2L + 2L - 10
38 + 10 = 4L
48 = 4L
L = 48/4
L = 12 cm
La longitud del rectángulo = 12 cm
Como L = 12, encontramos el ancho
Ancho = L - 5
= 12 cm - 5 cm
= 7 cm
El ancho del rectángulo = 7 cm
En la pregunta nos pidieron encontrar el área del rectángulo.
Área del rectángulo = Largo × Ancho
Área del rectángulo = 12 cm × 7 cm
Área del rectángulo = 84cm²
