Answer: C, 3500
Step-by-step explanation:
Each jump from year to year is multiplying by abt 1.6 (200/124 = 1.62, 322/200 = 1.61, etc.) so to find 1978 you'd multiply 2167 * 1.6
2167 * 1.6 = 3467.2 = closest to 3500
Answer:
x < 4
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
Step 2: Subtract x from both sides.
Step 3: Subtract 6 from both sides.
Step 4: Multiply both sides by 4/(-1).
Answer:
-4 and -16
Step-by-step explanation:
Let x = first number
Let y = second number
Given:
- The two numbers multiply to 64
⇒ xy = 64
Given:
- The two numbers add to -20
⇒ x + y = -20
Rewrite x + y = -20 to make x the subject:
⇒ x = -20 - y
Substitute into xy = 64 and solve for y:
⇒ (-20 - y)y = 64
⇒ -20y - y² = 64
⇒ y² + 20y + 64 = 0
⇒ (y + 4)(y + 16) = 0
⇒ y = -4, y = -16
As x + y = -20
If y = -4 then x = -16
If y = -16 then x = -4
Therefore, the two numbers are -4 and -16
Using it's concept, the desired probability is:
P(Female|Junior) = 75%.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 8 Junior Students, out of which 6 are Female, hence the probability is:
P(Female|Junior) = 6/8 = 0.75 = 75%.
