You have a plate of 40 cookies. Ten have chocolate chips and 15 have pecans. Of the cookies mentioned in the preceding
sentence, four have both chocolate chips and pecans. You select a cookie at random. What is the probability that your cookie has
chocolate chips or pecans?
(Express numbers in exact form. Use symbolic notation and fractions where needed.)
probability your cookie has chocolate chips or pecans:

Answers

Answer 1

Using Venn probabilities, there is a 0.525 = 52.5% probability that your cookie has chocolate chips or pecans.

What is a Venn probability?

In a Venn probability, two non-independent events are related with each other, as are their probabilities.

The "or probability" is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

For this problem, the events are given as follows:

Event A: Chocolate chips.Event B: Pecans.

From the text, the probabilities are given as follows:

[tex]P(A) = \frac{10}{40}[/tex].[tex]P(B) = \frac{15}{40}[/tex][tex]P(A \cap B) = \frac{4}{40}[/tex]

Hence the "or probability" is given by:

[tex]P(A \cup B) = \frac{10}{40} + \frac{15}{40} - \frac{4}{40} = \frac{21}{40} = 0.525[/tex]

0.525 = 52.5% probability that your cookie has chocolate chips or pecans.

A device produces random 64-bit integers at a rate of one billion per second. After how many years of running is it unavoidable that the device produces an output for the second time? Round to the nearest number of years.

Answers

Answer:

3171 × 10^(44) years

Step-by-step explanation:

For each bit, since we are looking how many years of running it is unavoidable that the device produces an output for the second time, the possible integers are from 0 to 9. This is 10 possible integers for each bit.

Thus, total number of possible 64 bit integers = 10^(64) integers

Now, we are told that the device produces random integers at a rate of one billion per second (10^(9) billion per second)

Let's calculate how many it can produce in a year.

1 year = 365 × 24 × 60 × 60 seconds = 31,536,000 seconds

Thus, per year it will produce;

(10^(9) billion per second) × 31,536,000 seconds = 3.1536 × 10^(16)

Thus;

Number of years of running is it unavoidable that the device produces an output for the second time is;

(10^(64))/(3.1536 × 10^(16)) = 3171 × 10^(44) years

In electronics, the formula V = IR is called Ohm's Law. It gives the relationship in a circuit between the voltage V (in volts), the current I (in amperes), and the resistance R (in ohms). Find R when I = 2 − 3i amperes and V = 34 + i volts.

Answers

Answer:

R = 5 + 8i (Ohm)

Step-by-step explanation:

R = V/I

= (34 + i)/(2 - 3i)

= 5 + 8i (Ohm)

Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8):(a)Compute the Euclidean distance between the two objects. (b) Compute the Manhattan distance between the two objects.

Answers

Answer:

(a) 6.708

(b) 11

Step-by-step explanation:

Tuples ( 22, 1, 42, 10) and (20, 0, 36, 8)

Euclidian distance formula  

[tex]D = \sqrt{(q1 -p1)^2 + (q2-p1)^2 + (q3 - p3)^2 + (q4 -p4)^2}[/tex]

D = [tex]\sqrt{(22-20)^2 + (1-0)^2 + (42 -36)^2 + (10 -8)^2 }[/tex]

   = [tex]\sqrt{(2)^2 + (1)^2 + (6)^2 + (2)^2}[/tex]

    = [tex]\sqrt{4 + 1 + 36 + 4 }[/tex]

     = [tex]\sqrt{45}[/tex]

 D    = 6.708

Therefore the Euclidean distance between the tuples is 6.708

Manhattan Distance formula

D = |q1-p1| + |q2 -p2| + |q3 -p3| + |q4-p4|

  = |22-20| + | 1-0| + | 42 -36| + | 10-8|

 = |2| + |1| + |6| + |2|

D = 11

Therefore the Manhattan distance is equal to 11

A football field is 300ft long a sloth moving very quickly travels 60ft every 5 minutes based on this ratio how many minutes would it take a sloth to travel the length of a football field

Answers

Answer:

25 minute

Step-by-step explanation:

Speed is the ratio of the total distance traveled  to the total time taken to reach this distance. The formula for speed is:

Speed = total distance / total time taken

The total distance covered by the sloth = 60 ft, and the time taken = 5 minutes, hence:

Speed = total distance / total time taken

speed of the sloth = 60 ft / 5 minutes = 12 ft per minute.

We can calculate the time taken for the sloth to travel the length of the football field (i.e. 300 ft)

speed = distance / time

12 ft/minute = 300 ft / time

time = 300 ft / (12 ft/minute)

time = 25 minute

A shop sells 3 different types of tea

300 g of Columbian tea costs £3.45
150 g of Indian tea costs £1.70
a) Work out the cost of 100g of each type of tea
b) Which type of tea is the cheapest?​

Answers

Answer:

The cheapest is the Kenyan tea which costs  £1.05  for each 100g.

Step-by-step explanation:

A)

200 g of Kenyan tea costs £2.10

1. Calculate the rate of each gram, by dividing 2.10/200

0.0105 x 100 =    £1.05  for each 100g

300 g of Columbian tea costs £3.45

1. Calculate the rate of each gram, by dividing 3.45/300

0.0115 x 100 =  £1.15 for each 100g

1. Calculate the rate of each gram, by dividing 1.70/150

150 g of Indian tea costs £1.70

0.01133333333 x 100 =  £1.133333333 for each 100g

B) The cheapest is the Kenyan tea which costs  £1.05  for each 100g.

Does the rule y = 6x7 represent an exponential function?
yes
no

Answers

No , the rule y = 6x ^7 does not represent an exponential function.

The exponential function is a mathematical function of the form f(x) = a^x. where "x" is a variable and "a" is a constant called the base of the function, which must be greater than 0. The exponential function is defined by the formula f(x) = a^x. where the input variable x is displayed as an exponent. An exponential curve depends on the exponential function and the value of  x.

We have given  y =6 x^7.

Here the variable is base & the exponent is an integer.

But an exponential function has a constant as its base and a variable as its exponent .

So, it does not represent an exponential function .

a: f(x)=60x-160
b:f(x)=-60x+160
c:f(x)=-80x +4
d: f(x)= 80x -4

Answers

Answer:

The equation that closely represents the graph is [tex]\mathbf{y=60x-160}[/tex]

Option A is correct.

Step-by-step explanation:

We need to find equation that represents the graph.

We can write equation in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

For finding the equation we need to find slope and y-intercept

Finding slope

The slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph we can find [tex]x_1=0, y_1=-160, x_2=1, y_2=-100[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-100-(-160)}{1-0} \\Slope=\frac{-100+160}{1}\\Slope=-100+160\\Slope=60[/tex]

We get Slope = 60

Finding y-intercept

Using point (0,-160) and slope m = 60, we can find y-intercept

[tex]y=mx+b\\-160=60(0)+b\\b+0=-160\\b=-160[/tex]

Writing the equation

So, the equation for given graph having slope m = 60 and y-intercept b =-160 is:

[tex]y=mx+b\\y=60(x)+(-160)\\y=60x-160[/tex]

So, The equation that closely represents the graph is [tex]\mathbf{y=60x-160}[/tex]

Option A is correct.
