Answer:
Step-by-step explanation:
'll just help with proving whether she is correct.
First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult
so remember keep, change, flip
keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1
so 5/2 divided by 1/4 becomes
5/2 * 4/1
which then solved becomes
20/2 which is simplified to 10
Hope this helps :)
Answer:
1.25% widgets from factory A fail.
Step-by-step explanation:
Probability of widgets that fail = 0.05
Probability of failing widget to belong from factory A = 0.25
Probability of failing widget to belong from factory B = 0.35
Probability of failing widget to belong from factory C = 0.40
Probability of factory A widgets failing = Probability of widgets failing * probability they belonged from factory A
Probability of factory A widgets failing = 0.05 * 0.25 = 0.0125
This probability stated as percentage: 1.25%

D. A=34, B=28
Step-by-step explanation:
In the bulletin points, it says that seconds 3-5 are decreasing. That means that those heights can't be higher than second 2 (34). The only option that works is option D.
----------------------
Option A is incorrect because it starts with 35ft which is higher than second 2(34) so that is automatically wrong.
Option B is incorrect because it is increasing instead of decreasing.
Option C is incorrect for the same reason as Option A: it starts with 35ft.
---------------------
Therefore, the only correct option is Option D.
Have a nice day!!
