Answer:
x ≥ -3
Step-by-step explanation:
The shaded circle means it is equal to as well.
Answer:
10^-5 or 1/100,000
Step-by-step explanation:
That probability of 5 events in a row is the 5th power of the probability of one of them, assuming they are independent.
0.1^5 = (10^-1)^5 = 10^-5
Let, Number of multiple choice = x
Number of short answer question = y
Now, x + y = 20
& 3x + 11y = 100
Multiply 1st equation by 3, and subtract from eq,2,
3x + 3y = 60
After subtraction,
8y = 40
y = 40/8
y = 5
Now, substitute in eq (1),
x + 5 = 20
x = 15
In short, There are 15 Multiple choice & 5 short answer questions
Hope this helps!
Answer: x > 5 and x < 10
Step-by-step explanation:
in the first inequality, divide both sides by -2 and remember to reverse the inequality sign when you divide by a negative number.
For the second one, add 4 to both sides.
A = -0.7
B = -9/16 (0.5623)
C = -0.4
D = -5/16 (0.3125)
The last option is correct
