In a large school, it was found that 77% of students are taking a math class, 74% of student are taking an English class, and 70

Iteru [2.4K]

Answer:

0.81 = 81% probability that a randomly selected student is taking a math class or an English class.

0.19 = 19% probability that a randomly selected student is taking neither a math class nor an English class

Step-by-step explanation:

We solve this question working with the probabilities as Venn sets.

I am going to say that:

Event A: Taking a math class.

Event B: Taking an English class.

77% of students are taking a math class

This means that $P(A) = 0.77$

74% of student are taking an English class

This means that $P(B) = 0.74$

70% of students are taking both

This means that $P(A \cap B) = 0.7$

Find the probability that a randomly selected student is taking a math class or an English class.

This is $P(A \cup B)$ , which is given by:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cup B) = 0.77 + 0.74 - 0.7 = 0.81$

0.81 = 81% probability that a randomly selected student is taking a math class or an English class.

Find the probability that a randomly selected student is taking neither a math class nor an English class.

This is

$1 - P(A \cup B) = 1 - 0.81 = 0.19$

0.19 = 19% probability that a randomly selected student is taking neither a math class nor an English class

Answer:

t $\leq$ 24

Step-by-step explanation:

we can add 5 to both sides

-t/6 $\geq$ -4

multiply both sides by 6

-t $\geq$ -24

divide by -1, when dividing by a negative, the inequality flips

t $\leq$ 24

Who walks the faster rate: someone who walks 60 feet in 10 seconds or someone who takes 5 seconds to walk 25 feet?

True [87]

To determine the rate that an individual walks. Take each set values and put in the following formula to solve for the rate.

Rate = number of feet/ seconds

Person 1 = 60 feet / 10 seconds = 6 feet/sec

Person 2 = 25 feet / 5 seconds = 5 feet/second

Person 1 walks at a faster rate than person 2.
