Strands of copper wire from a manufacturer are analyzed for strength and conductivity. The results from 100 strands are as follows: Strength High Low High conductivity 74 8 Low conductivity 15 3 a. If a strand is randomly selected, what is the probability that its conductivity is high and its strength is high

Answers

Answer 1

Answer:

0.74

Step-by-step explanation:

Given :

__________________ STRENGTH __

__________________High _ Low

High conductivity _____ 74 __ 8

Low conductivity _____ 15 ___ 3

Probability that conductivity is high and strength is high :

This the probability of High conductivity n High strength = P(High conductivity n High strength)

Probability = required outcome / Total possible outcomes

Required outcome = P(High conductivity n High strength) = 74 (from table)

Total possible outcomes = total sample size = 100

Hence,

P(High conductivity n High strength) = 74 / 100 = 0.74

Find values for a and b so that 2(3x+5)+ax=5(4x−b) is an identity equation.

Answers

Answer:

a=30 b=2 (not sure)

Step-by-step explanation:

Simplify first part : 2*3x+ 2*5= 6x+10+ax

Simplify 2nd part : 5*4x-5*b. 5x-5b

we have: 6x+10+ax=20x-5b.

we minus 6x from both sides

10+ax=14x+5b

Minus 10

ax=14x+5b-10

Divide x

a=14+5b-10

a=4+5b

divde 5

a/5= 4+b

perhaps it is 30

30/5=4+b

tan(10) = 0.1763

0.1763 = x / 500

Exercise 4.3. Determine the exact probability of drawing a 10 from a shuffled pinochle deck. (In a pinochle deck, there are 48 cards. There are six values: 9, 10, Jack, Queen, King, Ace. There are two copies of each value in each of the standard four suits: hearts, diamonds, clubs, spades.)

Answers

Answer:

[tex]\frac{1}{6}[/tex] probability of drawing a 10 from a shuffled pinochle deck.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Total of 48 cards.

Of those, there are 2*4 = 8 cards that are 10. So

[tex]p = \frac{8}{48} = \frac{1}{6}[/tex]

[tex]\frac{1}{6}[/tex] probability of drawing a 10 from a shuffled pinochle deck.
