For the members of a neighborhood meeting group, the probability of randomly selecting a member who likes to cook is 42%, the pr
Monica [59]

Answer: Probability of randomly selecting a member who likes to cook or likes to sew = 58%

Step-by-step explanation:

Since we have given that

Probability of a randomly selecting a member who likes to cook=P(C) = 42%

Probability of a randomly selecting a member who likes to sew =P(S)= 23%

Probability of a randomly selecting a member who likes to both cook and sew

P(C\cap S)=7\%

As we know the "Probability rules " :

P(C\cup S)=P(C)+P(S)-P(S\cap C)\\\\P(C\cup S)=42+23-7\\\\P(C\cup S)=58

So, Probability of randomly selecting a member who likes to cook or likes to sew = 58%

Travka [436]
We start with
$1,187.92
With the interest and the late fee charge
$1,187.92 (1 + 0.1225/12) + 30 = $1,230.05
With the interest minus the payment of $125
$1,230.05 (1 + 0.1225/12) - $125 = $1,117.60

The new principal after the latest payment is $1,117.60.

- 5.8c + 4.2 - 3.1 + 1.4c − 5.8c + 4.2 − 3.1 + 1.4c
Cerrena [4.2K]

Answer:

-8.8c + 2.2 OR SOLVED c = 0.25

Step-by-step explanation:

<u>Step 1:  Combine like terms</u>

- 5.8c + 4.2 - 3.1 + 1.4c − 5.8c + 4.2 − 3.1 + 1.4c

<em>-8.8c + 2.2</em>

<em />

<u>Step 2:  If needed solve for c</u>

-8.8c + 2.2 - 2.2 = 0 - 2.2

-8.8c / -8.8 = -2.2 / -8.8

<em>c = 0.25</em>

<em />

Answer:  -8.8c + 2.2 OR SOLVED c = 0.25
