Theoretical Probability (Pink Band) - 19/37
Their are 95 pink rubber bands (numerator) and when adding 95+90 = 185 (denominator) to get the theoretical probability you would get 95/185 which when simplified by the factor of 5 would be the same thing as 19/37.

Theoretical Probability (Brown Band) - 18/37

Their are 90 brown rubber bands (numerator) and we already know that are denominator will be 185 so we would get 90/185. This fraction is also divisible by a factor of 5 so when simplified you would get 18/37.

Experimental Probability (Pink/Brown Band) - 12/23 and 11/23

Pink Band: Their is a 36 (numerator) out of (36+33) 69 (denominator) chance of pulling a pink band so it would be written as 36/69 which is divisible by 3 and when simplified is written as 12/23.

Brown Band: Their is a 33 (numerator) out of our already known denominator 69 chance of pulling a brown band. When written as a fraction this would be 33/69 which is also divisible by 3 and when simplified 11/23.

We can conclude with this data that their is a slightly higher chance of pulling a pink rubber band compared to the experimental probability of picking a brown rubber band because we know that 12/23 > 11/23.

Please help me with the following questions. Thanks in advance!!

puteri [66]

Answer:

Step-by-step explanation:

In choices a and b, the bases are positive numbers greater than 1, and so these are growth functions. In c and d, the bases are between 0 and 1, and thus these are decay functions.

In the second problem we have 3ln(x + 1). Rewrite this as ln(x + 1)^3.

We also have 9ln(x - 4). Rewrite this as ln(x - 4)^9.

Because of the + sign connecting ln(x + 1)^3 and ln(x - 4)^9, these two logs combine to form

ln [ (x + 1)^3 ] * (x - 4)^9 (the log of a product).

Now we have:

ln [ (x + 1)^3 ] * (x - 4)^9 - 4ln(x + 7), or:

[ (x + 1)^3 ] * (x - 4)^9

ln ------------------------------------

(x + 7)^9

Solve the system of equations using substitution or elimination. Show all work for credit.

Tomtit [17]

Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
$y = \frac{ - \frac{1}{2} x + 2}{3} \\ y = - x + 9$

Since both expressions are equal to y, you have to equal both expressions like this:
$\frac{ - \frac{ 1}{2}x + 2 }{3} = - x + 9$
Now you can solve the equation:
$- \frac{1}{2} x + 2 = 3( - x + 9) \\ - \frac{ 1}{2}x + 2 = - 3x + 27 \\ \\ - \frac{1}{2} x + 3x = 27 - 2 \\ \frac{5}{2} x = 25 \\ x = \frac{(25)(2)}{5} \\ x = 10$
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result

$y = - (10) + 9 \\ y = - 1$
So, the answer is x=10 and y=-1

Jessica is measuring two line segments. The first line segment is 30 cm long. The second line segment is 500 mm long. How long a

ElenaW [278]

Answer:

80 cm

Step-by-step explanation:

To find the length of both segments together, convert the lengths into one unit measure. Convert 500 mm into centimeters by dividing it by 10. 500/10 = 50 cm. Now add 30 + 50 = 80 cm. The segment is 80 cm long.
