Answer:

1.) because 10^3=1000 and 11^3 = around 1330 we know that the answer must fall between 10 and 11. Because they're pretty much equal distance I would estimate it to be around 10.5 (if you need an exact answer it's 2∛150)

2.) because 11^2=121 and 10^2= 100 we know that it must fall between 10 and 11. Because these are pretty much equal distance as well I would estimate it to be around 10.5 as well (if you need an exact answer it's 4√7)

A bag contains five red marbles, two orange marbles, one yellow marble, and two green marbles. Two marbles are drawn from the ba

Naya [18.7K]

Option C: 0.8889 is the probability of choosing an orange marble and a green marble.

<h2>Given that:</h2>

Number of red marbles is 5

Number of orange marbles is 2

Number of yellow marbles is 1.

Number of green marbles is 2.

<h2>Explanation and Calculations:</h2>

So there are in total 10 marbles.

Two marbles can be chosen in $^{10}C_2$ ways = 90/8

Now the favorable event is when one green marble and one orange marble is chosen. The number of ways this can be done is $^{2}C_1 \times ^{2}C_1 = 4$

The resultant probability is calculated by:

$P(E) = \dfrac{Number \:of\: Favourable \:cases}{ Number\: of\: total \:cases}\\= \dfrac{4}{\frac{90}{2}}\\\\= \dfrac{8}{90}\\\\\approx 0.08889$

Thus the needed probability is 0.08889 given by option C.

Answer:

$\boxed{\bold{True}}$

Step By Step Explanation:

Equation One:

Multiply Both Sides By One (Reverse The Inequality)

$\bold{\left(-\frac{2}{5}x\right)\left(-1\right)$

Simplify

$\bold{\frac{2}{5}x$

Multiply Both Sides By 5

$\bold{5\cdot \frac{2}{5}x$

Simplify

$\bold{2x$

Divide Both Sides By 2

$\bold{\frac{2x}{2}$

Simplify

$\bold{x$

-------

Equation Two:

Subtract $\bold{\frac{3}{4} }$ From Both Sides

$\bold{-x+\frac{3}{4}-\frac{3}{4}$

Simplify

$\bold{-x$

Multiply Both Sides By -1 (Reverse The Inequality)

$\bold{\left(-x\right)\left(-1\right)>\frac{37\left(-1\right)}{4}}$

Simplify

$\bold{x>-\frac{37}{4}}$

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
