Answer:

$\frac{x+12}{4(x+3)}$

Step-by-step explanation:

we have

$(\frac{3}{x} +\frac{1}{4}):(1+\frac{3}{x})$

Multiply by 4x numerator and denominator to remove the fractions

$(\frac{3}{x}(4x) +\frac{1}{4}(4x)):(1(4x)+\frac{3}{x}(4x))$

$\frac{12+x}{4x+12}$

Factor 4 in the denominator

$\frac{x+12}{4(x+3)}$

Find the circumference of the circle and round to the nearest tenth

VLD [36.1K]

Answer:

The circumference is 45.2yd

Step-by-step explanation:

Given

$d = 14.4$ --- diameter

Required

Determine the circumference

The circumference is calculated as:

$C =\pi d$

So, we have:

$C =\pi * 14.4$

Take pi a 3.14

$C =3.14 * 14.4$

$C =45.216$

Approximate

$C =45.2yd$

Me ayudan hacer este ejercicio con los pasos

QveST [7]

Answer:

A) 21/7, or 3

B) 36/5, or 7 1/5

C) 35/25, or 1 15/25, or 1 3/5

D) 54/12, or 4 6/12, or 4 1/2

Step-by-step explanation:

8/7 plus 13/7. You add the numerators (the numbers on top) together. That makes 21. The denominator (the numbers on bottom) stays the same. So it would be 21/7. 7 fits into 21, 3 times.

8/7 más 13/7. Agrega los numeradores (los números en la parte superior) juntos. Eso hace 21. El denominador (los números en la parte inferior) permanece igual. Entonces sería 21/7. 7 encaja en 21, 3 veces.

8/7 plus 13/7. Vous ajoutez les numérateurs (les chiffres du haut) ensemble. Cela fait 21. Le dénominateur (les chiffres du bas) reste le même. Donc, ce serait 21/7. 7 correspond à 21, 3 fois.

8/7 plus 13/7. Quarum numeratores addere (supra de numero) una. 21. Quod facit denominator est (per numeros in fundo) manebit. Ita esset 21/7. Vicium, in VII XXI, III tempora.

Which is the best estimate of the correlation coefficient for the scatter plot?

olga55 [171]

Answer:

The best estimate of the correlation coefficient is 0.9 from the given data.

Step-by-step explanation:

From the scatter plot, the line of best fit will have a positive slope.

So, the correlation coefficient , $\rho$ is greater than 0.

so, $\rho$ ≠ - 0.9

Also, there is a deviation from absolute linearity.

So, $\rho$ ≠ 1

Again from the scatter plot it is closer to linearity than further.

Hence, $\rho$ ≠ 0.3 .

So $\rho$ = 0.9

Calculate the average rate of change over the interval 2

Morgarella [4.7K]

Answer:

Average rate of change over the interval 2<= x <= 5:

y = 3x + 5: 3

y = 3x^2 + 1: 21

y = 3^x: 78

Step-by-step explanation:

2<= x <= 5

Average rate of change over the interval 2<= x <= 5:

y = 3x + 5

y(5) = 3(5) + 5 = 20

y(2) = 3(2) + 5 = 11

Average rate of change = (20 - 11)/(5-2) = 9/3 = 3

y = 3x^2 + 1

y(5) = 3(5^2) + 1 = 75 + 1 = 76

y(2) = 3(2^2) + 1= 13

Average rate of change = (76 - 13)/(5-2) = 63/3 = 21

y = 3^x

y(5) = 3^5 = 243

y(2) = 3^2 =9

Average rate of change = (243-9)/(5-2) = 234/3 = 78
