Answer:
Dr. Kora will pay an interest of $6,000
Step-by-step explanation:
Simple interest = P × R × T
Where:
P = Principal = $8000
R = Rate = 7.5% = 0.075
T = Time = 10 years
∴ Simple interest = 8000 × 0.075 × 10 = $6,000
Therefore Dr. Kora will pay an interest of $6,000
Answer:
- housing, $1056
- food, $552
- transportation, $408
- savings, $240
- clothing, $144
Step-by-step explanation:
Multiply the budget total by the percentage for each category:
- housing: 44% × $2400 = $1056
- food: 23% × $2400 = $552
- clothing: 6% × $2400 = $144
- transportation: 17% × $2400 = $408
- savings: 10% × $2400 = $240
__
Find "the rest" by subtracting the total of percentages from 100%, or by subtracting the total of budget categories from $2400. Here, everything (not including savings) adds to 90% × $2400 = $2160, so the amount to savings is 10%, or $240.
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 
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 
The resultant probability is calculated by:
Thus the needed probability is 0.08889 given by option C.

Answer:
-20
Step-by-step explanation:
(r + b − g)(b + g)
we have fom statement:
r = 9
b = 5
g= −6
so we have:
(r + b − g)(b + g)= (9+5-(-6))*(5+(-6))
(r + b − g)(b + g)= (14+6)*(-1)
(r + b − g)(b + g)= -20
