Iwill reward branliest and 99 what is the first step in which the student made an error? step 1, because the student should have written a compound statement with “and.” step 2 ,because the student should have graphed the inequalities step 3, because the solution should also include all the values for x between the two given values. step 4, because the solution is one continuous interval.

Step 3, because the solution should also include all the values for x between the two given values

Step-by-step explanation:

step 1

we have

step 2

The graph in the given problem

step 3

Identify the solution when

so

using a graphing tool

The solution is the interval  -----> [3,5]

see the attached figure

All real numbers greater than or equal to 3 and less than or equal to 5

therefore

The first step in which the student made an error is step 3

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
