Answers

Answer:

[tex] \huge \boxed{ \sf{ \{ 0 \} }}[/tex]

Step-by-step explanation:

Given :

[tex] \sf{A} \: = \: [/tex] { -6 , 0 , 6 }

[tex] \sf{B} \: = [/tex]{ -1 , 0 , 1 }

To find :

A ∩ B

Solution :

A ∩ B = { -6 , 0 , 6 } { -1 , 0 , 1 }

A ∩ B = { 0 }

Remember : In case of intersection , the common element of two sets A and B should be listed in a single set. So, the intersection of sets A and B is the set of all elements which belong to both A and B. The intersection of sets A and B is denoted by ( A ∩ B ) and read as A intersection B.

Hope I helped!

A coal company wants to determine a 95% confidence interval estimate for the average daily tonnage of coal that it mines. Assuming the company reports that the standard deviation of daily output is 200 tons, how many days should it sample so that the margin of error will be 39.2 tons or less?

Answers

Answer:

It should be 100 days sample so that the margin of error will be 39.2 tons or less

Step-by-step explanation:

We are given that A coal company wants to determine a 95% confidence interval estimate for the average daily tonnage of coal that it mines.

[tex]\alpha = 0.05[/tex]

To Find two tailed critical value using Z table

[tex]Z_{\frac{\alpha}{2}}=Z_{\frac{0.05}{2}}=\pm 1.96[/tex]

Margin of error = ME = 39.2

[tex]\sigma = 200[/tex]

Formula : [tex]n = (\frac{Z_{\frac{\alpha}{2}} \times \sigma}{ME})^2[/tex]

[tex]n = (\frac{1.96 \times 200}{39.2})^2[/tex]

n=100

Hence it should be 100 days sample so that the margin of error will be 39.2 tons or less

Step-by-step explanation:

The required number of employees being laid off is 90.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Given that,

The number of employees laid off last year was 75.

The percentage increase in laid off  for present year is 20%.

The number of employees laid off can be calculated as follows,

75 + 20% of 75

= 75 + 20/100 × 75

= 75 + 15

= 90

Hence, the number of employees laid off in the present year is 90.

In a study of the television viewing habits of children, a developmental psychologist selects a random sample of 300 first graders - 100 boys and 200 girls. Each child is asked which of the following TV programs they like best: The Lone Ranger, Sesame Street, or the Simpsons.

Complete the following table:

Answers

Answer:

20, 50, 70, 110

Step-by-step explanation:

boys x simpsons: 20

girls x long ranger: 50

girls x simpsons: 70

total x sesame street: 110

have a great day :)

20 girls watch Long Ranger , 110 first graders watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.

What is random sampling?

" Random sampling is a process of observing samples using such technique that each sample has equal probability."

According to the question,

As per the information of random samples given in the table,

Total number of boys are  = 100

Total number of girls = 200

For boys

Long Ranger + Sesame Street + Simpsons = 100

⇒  50 + 30 + Simpsons = 100

Number of boys view Simpsons = 100 - 80

                                                          = 20

In Long  ranger column,

50 Boys + ___girls = 100

Number of girls watching Long Ranger = 100 -50

                                                                   = 50

In Sesame street

30 boys + 80 girls = 110 Total viewers

Number of girls watching Simpsons = 90 -20

                                                            = 70

Hence, 20 girls watch Long Ranger , 110 total boys and girls watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.

Answers

Given parameters:

Actual length = 260m

Drawing length = 286mm

Unknown:

Scale used = ?

Solution:

A scale compares drawing length to ground distance;

                    To find the scale,

Express the two quantities in the same unit;

       actual length  = 260 x 10⁻³m = 0.26mm

  Now;

           drawing length : actual length

                  286mm : 260 x 10⁻³mm

                  divide by 286;

                     1mm on drawing  : 9 x 10⁻⁴mm on map

   or;

                     1mm on drawing is 0.9m on ground

The world population at the beginning of 1980 was 4.5 billion. Assuming the population continued to grow at the rate of approximately 1.3% per year, find a function Q(t) giving the population of the world (in billions) as a function of time t (in years)

Answers

Answer:

The function Q(t) = 4.5 billion (1.013)^t will give the population in t years

Step-by-step explanation:

Here, we want to write a function

The growth percentage is 1.3% = 1.3/100 = 0.013

The function Q(t) will be an exponential function and it will be represented as;

Q(t) = I ( 1 + r)^t

where I is the initial world population at 1980 = 4.5 billion

r is the growth percentage = 1.3% = 0.013

t is the time in years

Substituting these values, we have;

Q(t) = 4.5 billion (1 + 0.013)^t

Q(t) = 4.5 billion (1.013)^t

The equation that shows the amount of snow that has fallen after [x] hours can be written as y = 2x

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is that snow Is falling steadily such that after 2 hours, 4 inches of snow has fallen.

In 2 hours 4 inches of snow has fallen.

Then, in 1 hour → (4/2) → 2 inches of snow has fallen.

So, in 6.5 hours → 2 x 6.5 → 13 inches

Hence, in x hours2x inches

The complete table is shown below

Time (in hours)                        Snow (in inches)

0                                                      1

x                                                      2x

The equation that shows the amount of snow that has fallen after [x] hours can be written as -

y = 2x

Therefore, the complete table is given as follows -

=_______ft

Answers

Answer:

At 19.14 feet the top of the ladder meet the house.

Step-by-step explanation:

It is given that,

A large ladder leans against a house with the base of the ladder 5.8 horizontal feet from  the base of the house.

Slope of the ladder, m = 3.3 feet/foot

We need to find at what height does the top of the ladder meet the house. Let it is h.

Base, b = 5.8 feet

It will form a right angle triangle

Slope=h/base

h = slope × base

h = 3.3 × 5.8

h = 19.14 feet

So, at 19.14 feet the top of the ladder meet the house.
