Answer:

Emanuel did a mistake in her first step.

Step-by-step explanation:

The given expression is

\left(\dfrac{3}{5}\right)\left(\dfrac{4}{9}\right)\left(-\dfrac{1}{2}\right)

Emanuel solve this problem but she did a mistake in her first step. She distributes negative sign with 1 and 2 both which is incorrect. We can write negative sign with either 1 or 2 but not both.

Correct steps are:

Step 1:

\dfrac{(3)(4)(-1)}{(5)(9)(2)}

Step 2:

\dfrac{-12}{90}

Step 3:

-\dfrac{2}{15}

Therefore, she did a mistake in her first step.

Divide 24 milliliters into the ratio of 6:2<br><br> What is the larger value?
Rashid [163]

Answer:

18 and 6

Step-by-step explanation:

Rn = 6   Ratio numerator

Rd = 2 Ratio Denominator

Rs = Rn + Rd

Rs = 6 + 2

Rs = 8

Ratio Sum

a = 24 Amount to Divide

M = a ÷ Rs

M = 24 ÷ 8

M = 3 Multiplier Ratio Division Calculation

Rr = Rn × M : Rd × M

Rr = 6 × 3 : 2 × 3

Rr = 18 : 6

A.) write an equation in slope intercept form for the total cost of any number of tickets at 7 tickets for $5.
marta [7]
Slope intercept form is y = mx + b

7 tickets for $5 means that 1 ticket costs 5/7 dollars

So for part a, the slope intercept form would be:

y = \frac{5}{7}x

where x is the number of tickets, and y is the price.

For part b)

The slope intercept form is:
y = 25x

where x is the number of all you can ride wristbands you buy, and y is the total price.

The Eco Pulse survey from the marketing communications firm Shelton Group asked individuals to indicate things they do that make
BabaBlast [244]

Answer:

a) 0.54 = 54% probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both.

b) 0.46 = 46% probability that a randomly selected person will not feel guilty for either of these reasons

Step-by-step explanation:

We use Venn's Equations for probabilities.

I am going to say that:

P(A) is the probability that a randomly selected person will feel guilty about wasting food.

P(B) is the probability that a randomly selected person will feel guilty about leaving lights on when not in a room.

0.12 probability that a randomly selected person will feel guilty for both of these reasons.

This means that P(A \cap B) = 0.12

0.27 probability that a randomly selected person will feel guilty about leaving lights on when not in a room.

This means that P(B) = 0.27

0.39 probability that a randomly selected person will feel guilty about wasting food

This means that P(A) = 0.39

a. What is the probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both (to 2 decimals)?

P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.39 + 0.27 - 0.12 = 0.54

0.54 = 54% probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both.

b. What is the probability that a randomly selected person will not feel guilty for either of these reasons (to 2 decimals)?

p = 1 - P(A \cup B) = 1 - 0.54 = 0.46

0.46 = 46% probability that a randomly selected person will not feel guilty for either of these reasons
