Answer:

The value of the sum of n and -1=5

Step-by-step explanation:

Step 1

Get the value of n using the equation below;

The sum of n and 4 is 10 can be expressed in equation form as follows;

n+4=10...equation 1

solving for n;

n=10-4

n=6

The value for n=6

Step 2

Express the sum of n and -1 as follows

n+(-1)=unknown...equation 2

using the value of n solved in equation 1 in equation 2

replace using;

n=6

6+(-1)=6-1=5

The value of the sum of n and -1=5

According to the Stack Overflow Developers Survey of 20184, 25.8% of developers are students.The probability that a developer is
murzikaleks [220]

Answer:

0.0326 = 3.26% probability that she is a student.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Woman developer

Event B: Student

Probability that the developer is a woman:

7.4% of 25.8%(students).

76.4% of 100 - 25.8 = 74.2%(not students). So

P(A) = 0.074*0.258 + 0.764*0.742 = 0.58598

Student and woman developer.

7.4% of 25.8%(students), so

P(A \cap B) = 0.074*0.258 = 0.019092

If we encounter a woman developer, what is the probability that she is a student

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.019092}{0.58598} = 0.0326

0.0326 = 3.26% probability that she is a student.

Given: -1/2x>6. Choose the solution set
Step2247 [10]

Answer:

B

Step-by-step explanation:

multiply both sides by 2 to eliminate the fraction

- x > 12

multiply both sides by - 1

Remembering to reverse the inequality symbol as a consequence

x < - 12 ← reverse symbol

⇒ { x | x ∈ R, x < - 12 } → B
