Answer:

This is 0.14 to the nearest hundredth

Step-by-step explanation:

Firstly we list the parameters;

Drive to school = 40

Take the bus = 50

Walk = 10

Sophomore = 30

Junior = 35

Senior = 35

Total number of students in sample is 100

Let W be the event that a student walked to school

So P(w) = 10/100 = 0.1

Let S be the event that a student is a senior

P(S) = 35/100 = 0.35

The probability we want to calculate can be said to be;

Probability that a student walked to school given that he is a senior

This can be represented and calculated as follows;

P( w| s) = P( w n s) / P(s)

w n s is the probability that a student walked to school and he is a senior

We need to know the number of seniors who walked to school

From the table, this is 5/100 = 0.05

So the Conditional probability is as follows;

P(W | S ) = 0.05/0.35 = 0.1429

To the nearest hundredth, that is 0.14

F(x )=x square +6x + 5 what is the x intercept to graph f(x)
siniylev [52]

Answer:

(-5, 0)

(-1, 0)

Step-by-step explanation:

x-intercepts are points where the graph intersects the x-axis (or when y = 0)

Step 1: Write out function

f(x) = x² + 6x + 5

Step 2: Factor

f(x) = (x + 5)(x + 1)

Step 3: Find binomial roots

x + 5 = 0

x = -5

x + 1 = 0

x = -1

Alternatively, you can graph the function and analyze the graph for x-intercepts:

Find Four constructive odd integers whose sum is 224 what is the largest number
rusak2 [61]

Answer:

53, 55, 57, and 59

Step-by-step explanation:

Let the numbers be

x, x +2, x +4, and x+6. Then

x + x+2 + x +4 + x + 6 = 224     Combine like terms

                      4x + 12 = 224     Subtract 12 from each side

                             4x = 212      Divide each side by 4

                               x = 53

The four consecutive integers are 53, 55, 57, and 59.

<em>Check: </em>

53 + 55 + 57 + 59 =224
