Sydney has index cards numbered 1 through 10 and determines that the probability of drawing a 4 is 3 out of 10. If she draws cards 100 times, how many times can she expect to draw a 4?

Step-by-step explanation:

In this problem, we are going to find the probability of obtaining/drawing a 4 after 100 trials

Given that the probability of drawing a 4 out of 10 trials  is 3/10

therefore the probability of drawing a 4 out of after 100 trials

= (3/10)*100

= 3*10

= 30

Hence the probability of drawing 4 after 100 trials are 30 times

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
