We have: 5m 75cm = 5.75 m

So the length of each piece is : $l = \frac{5.75}{5} =1.15$

ok done. Thank to me :>

Use the following problem to answer questions 8 and 9. A television manufacturer has three locations where it is finally assembl

Nonamiya [84]

Answer:

The probability of finding a non-defective television is 0.9815.

Step-by-step explanation:

We are given that a television manufacturer has three locations where it is finally assembled. Plants A, B, and C supply 65%, 15%, and 20% respectively of the televisions used by the manufacture.

Quality control has determined that 1.5% produced by Plant A are defective, while plants B and C have 2.5% defective products.

Let Probability that Plant A supply televisions = P(A) = 0.65

Probability that Plant B supply televisions = P(B) = 0.15

Probability that Plant C supply televisions = P(C) = 0.20

Also, let D = event that television is defective

Probability that television is defective given that it is supplied by Plant A = P(D/A) = 0.015

Probability that television is defective given that it is supplied by Plant B = P(D/B) = 0.025

Probability that television is defective given that it is supplied by Plant C = P(D/C) = 0.025

Now, to find the probability of finding a non-defective television firstly we will find the probability of a defective television.

Probability of a defective television is given by;

= P(A) $\times$ P(D/A) + P(B) $\times$ P(D/B) + P(C) $\times$ P(D/C)

= 0.65 $\times$ 0.015 + 0.15 $\times$ 0.025 + 0.20 $\times$ 0.025

= 0.00975 + 0.00375 + 0.005

= 0.0185

Now, probability of finding a non-defective television = 1 - Probability of a defective television

Probability of finding a non-defective television = 1 - 0.0185

= 0.9815

Therefore, the probability of finding a non-defective television is 98.15%.

here are the numbers of 15 people ate out last month. 6,5,5,3,5,4,3,6,4,3,6,5,3,7,6 find the modea of this data set

Taya2010 [7]

Answer: 3 and 5

Step-by-step explanation: The mode is the number that appears most frequently in a data set.

Although it's optional I recommend writing these integers from least to greatest so it will be easier to see what number occurs most frequently.

Notice that there are two numbers (3 and 5) that appear most often (and the same number of times) which means the data set has two modes. When a data set has two modes, this is called bimodal.
