2 answers:
Answer:
7.1 units.
Step-by-step explanation:
It is given that cd is congruent to df, e bisects df and cd= 14.2.
We have to find the measure of ef.
Using given information we get
(Measure of congruent segments are equal) ... (1)
(e bisects df) ... (2)
Using (1) and (2) we get
Hence, the measure of ef is 7.1 units.

Step-by-step explanation:
Given :
Ambell company uses or procures batteries from two manufacturers.
The life of a battery in critical tool is at = 32 hours
Ambell uses 70% of its batteries from manufacturer 1 and out of that 90% batteries lasts for about 40 hours.
Similarly, 75% of the batteries procured from the manufacturer 2 lasts for about 40 hours.
Therefore, the probability that a battery is form manufacturer 1 is :
= 0.625
Arithmetic sequences have a common difference between consecutive terms.
Geometric sequences have a common ratio between consecutive terms.
Let's compute the differences and ratios between consecutive terms:
Differences:
Ratios:
So, as you can see, the differences between consecutive terms are constant, whereas ratios vary.
So, this is an arithmetic sequence.
