To calculate, begin by determining the total number of sweets: 15 + 16 + 19 equals 50. Next, combine the amounts of caramel and dark chocolates: 16 + 15 results in 31. For the probability, create a fraction where the numerator consists of the combination of caramel with dark chocolates, and the denominator is the total number of chocolates: 31/50. Thus, Amber has a 31 out of 50 likelihood of selecting either a caramel chocolate or a dark chocolate.

Response:

31/50

Detailed explanation:

If Amber is offered a chocolate from the bag, her chance of randomly choosing between a caramel chocolate or a dark chocolate is 31/50.

tester [12383]

Response:

Move 2 units to the left

Reflect the graph across the y-axis

Expand horizontally by a factor of 2

Lift vertically by 2 units

Detailed explanation:

Provided:

Basic function: f(x)=\log x

Transformed function: f(x)=\log(-2x-4)+2

Extract -2 from the transformation function f(x)

f(x)=\log[-2(x+2)]+2

Now, we can observe the step-by-step transformations

f(x)=\log x

Move 2 units to the left ( x → x+2 )

f(x)=\log(x+2)

Reflect the graph across the y-axis ( (x+2) → - (x+2) )

f(x)=\log[-(x+2)]

Expand horizontally by a factor of 2 [ -x(x+2) → -2(x+2) ]

f(x)=\log[-2(x+2)]

Lift vertically by 2 units [ f(x) → f(x) + 2 ]

f(x)=\log[-2(x+2)]+2

Simplifying the function:

f(x)=\log(-2x-4)+2

Thus, applying four transformation steps results in the new function f(x)=\log(-2x-4)+2

What is a rational number that is located between 31.5 and 31.6
Svet_ta [12734]
A rational number refers to any number that can be written as a fraction, such as 2, -3, 2/3, etc.

Essentially, any non-repeating number found between 31.5 and 31.6 would suffice.

Examples include: 31.51, 31.52, 31.568, 31.599

I suggest 31.55 since it’s straightforward and can be expressed as the fraction: 361/20

Leona [12618]
Mel descends 50-35=15 feet in 5-2=3 seconds. Thus, her descent rate is 15/3=5 ft/sec.
Victor descends 60-50=10 feet in 4-1=3 seconds. Hence, his descent rate is 10/3=3⅓ ft/sec. Mel is faster, traveling at 5 ft/sec.

Yolanda is buying supplies for school. She buys n package of pencils at $1.40 per package and m pads of paper at $1.20 each. Wha
Inessa [12570]

To tackle this issue, we need to clarify what each variable stands for. Here, n indicates the number of pencil packages purchased by Yolanda, while m represents the number of paper pads she buys. We calculate the total cost by multiplying these variables by their individual prices, which helps us determine the expense for both pencil packages and pads of paper.

The expression "1.4n" indicates the overall cost for n pencil packages.

On the other hand, "1.2m" signifies the complete expense for m pads of paper.

As we sum these two expressions, the resulting total reflects the overall expenditure for both items.

The equation "1.4n + 1.2m" summarizes this calculation.

I hope this provides clarity!
