Answer:

x = -2 or x = -3

Step-by-step explanation:

Solve for x over the real numbers:

x^2 + 5 x + 6 = 0

The left hand side factors into a product with two terms:

(x + 2) (x + 3) = 0

Split into two equations:

x + 2 = 0 or x + 3 = 0

Subtract 2 from both sides:

x = -2 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = -2 or x = -3

In a circle of radius 60 inches, a central angle of 35° will intersect the circle forming an arc of length

Dmitriy789 [7]

$\bf \textit{arc's length}\\\\
s=\cfrac{\theta \pi r}{180}~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
r=60\\
\theta =35
\end{cases}\implies s=\cfrac{(35)(\pi )(60)}{180}\implies s=\cfrac{35\pi }{3}$

How many times greater is the value of 5 in 3,590 than the value of 5 in 359 ?

Tresset [83]

Answer:

10 times greater is the value of 5 in 3,590 than the value of 5 in 359.

Step-by-step explanation:

To find : How many times greater is the value of 5 in 3,590 than the value of 5 in 359 ?

Solution :

The place value stem is

Thousand Hundred Tens Ones

1000 100 10 1

The value of 5 in 3,590 is at hundred place

So, $5\times 100=500$

The value of 5 in 359 is at tens place

So, $5\times 10=50$

Number of time greater is the value of 5 in 3,590 than the value of 5 in 359 is given by,

$n=\frac{500}{50}$

$n=10$

Therefore, 10 times greater is the value of 5 in 3,590 than the value of 5 in 359.

Data with a correlation coefficient of 0.05 has a _[blank A]_ correlation, and data with a correlation coefficient of −0.80 has

Liula [17]

Answer:

Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while

Correlation Coefficient r value of 0.80 means a strong positive relationship

Step-by-step explanation:

Correlation Coefficient (r) signifies the strength of relationship which exists between two linear variables. The value of r ranges from - 1 to + 1 where positive and negative values signifies a positive and negative relationship relationship respectively.

The closer the r value is to either +1 or - 1, the greater the strength of the relationship while a r value of 0 means, there is no relationship between the two variables.

Hence in the scenario above :

Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while

Correlation Coefficient r value of 0.80 means a strong positive relationship
