The Frequency Distribution Shows The Number Of Registered Motor Vehicles For A Random Sample Of 200 California

Answers

Answer 1

Answer:

1). Mean = 2.275

2). Median = 2 vehicles

Step-by-step explanation:

From the given table,

Number of vehicles (x)         Frequency (f)      (f)×(x)             Cumulative freq.

                  0                                    11                  0                           11

                  1                                     52                52                        63

                  2                                    66                132                      129

                  3                                    35                105                      164

                  4                                    19                  76                       183

                  5                                    12                  60                       195

                  6                                     5                  30                       200

                                                                          [tex]\sum (f\times x) = 455[/tex]

Number of households = 200

Mean = [tex]\sum \frac{f.x}{n}[/tex]

          = [tex]\frac{455}{200}[/tex]

         = 2.275

Median = value of [tex]\frac{(n+1)}{2}th[/tex] observation

             = value of [tex]\frac{201}{2}th[/tex] observation

             = Value of 100.5th observation

             = Since 100.5th observation lies in the row of cumulative freq. = 129

             = 2

Therefore, median number of registered vehicles per California household

= 2 vehicles

Answer:

∠ ABC = 50°

Step-by-step explanation:

2x - 50 and x are corresponding angles and congruent, thus

2x - 50 = x ( subtract x from both sides )

x - 50 = 0 ( add 50 to both sides )

x = 50

Side length 9, 12, 17 forms a obtuse angled triangle.

What is Pythagorean triplets?

"Pythagorean triplets are combination of such three numbers which satisfy the Pythagoras theorem a² + b² = c²."

Formula used

Pythagoras triplet

c = hypotenuse

'a' and 'b' other two sides of a triangle

a² + b² = c² (Right angled triangle)

a² + b² ≤ c² (Obtuse angled triangle)

a² + b² ≥ c² (Acute angled triangle)

According to the question,

Given

Side length of a triangle = 9, 12, 17

Substitute the value in the formula of Pythagoras triplet we have,

a² = 81

b² =144

c² =289

c² > a² +b²

Therefore, triangle with side length 9, 12, 17 forms a obtuse angled triangle

Step-by-step explanation:

Given: Scale : 1 cm : 2.5 inches

A rectangular wall of her birdhouse has a drawing length of 2 cm and a width of 4 cm. What will the actual area of the wall be?

So, Actual length = 2  x 2.5 inches = 5 inches

Actual width = 4 x 2.5 inches = 10 inches

Actual area = Actual length x Actual width

= 5 x 10 = 50 sq. inches

Show all of your work and check your answer to make sure that it makes the inequality true.

Answers

Answer:

32.25 necklaces

Step-by-step explanation:

Given that the expected profit upon deduction of booth rent and material cost is at least $300

Given

let the number of necklaces be x

booth rent= $200

The cost of materials for the necklaces = $4.5x

the selling price for all the necklaces =$20x

total expenses= booth rent+cost of material = 200+4.5x

profit = selling price -total expenses

20x-300>200+4.5x+

B. the possible solution is the value of x i.e the number of necklaces to

be sold to make a profit of $300

20x-300>200+4.5x

20x-4.5x=200+300

15.5x=500

x=500/15.5

x=32.25

The Jewelry artist must have to sell a total of approximately 32.25 necklaces

In your own words, explain how to find the rate of change of the following graph at x=1. Then find the rate of change at x=1.

Answers

Answer:

Rate of change of the graph = 1

Step-by-step explanation:

Rate of change of the graph at any point is defined by the slope of the line at that point.

Since, slope of a line between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{\triangle y}{\triangle x}[/tex]

In other words, slope of a line between two points is given by the ratio of rise and run of the line between the given points.

Therefore, slope of the line passing through two points (0, 2) and (1, 3) will be,

m = [tex]\frac{3-2}{1-0}[/tex]

m = 1

Rate of change at x = 1 is 1.

how many gallons will be in 1 min ?

how many gallons will be in 3 min?

and how long it takes for 40 gallons?

Answer:

1.6 gallons

4.8 gallons

25 mins

Step-by-step explanation:

This question has to do with proportion.

If it takes 0.5 mins for the tank to get 0.8 gallons

in 1 minute the tank will get 0.8 * 1/0.5 = 1.6 gallons

In 3 minutes the tank will get 3 * 1.6 gallons = 4.8 gallons

if it takes 1 min to get 1.6 gallons

it will take x mins to get 40 gallons

x = 1 * 40/1.6 = 25 mins

if abc is an isosceles triangle and m∠A=40º,what are possible measures for angles B and C

Answers

Answer:

They could both be 70

Step-by-step explanation:

The reason why is because if you subtract 40 from 180 you get 140 and that can be evenly split in 2 ways by 70.

An isosceles triangle is one with two equal-length sides. The possible measures for ∠B and ∠C are 70°.

What is an isosceles triangle?

An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.

Since in an isosceles triangle the measure of any two angles is equal to each other. Therefore, assuming that ∠B and ∠C are those equal angles.

Now, given that the measure of ∠A is 40°. Therefore, the sum of the measure of all the angles of the triangle can be written as,

∠A + ∠B + ∠C  = 180°

40° + ∠B + ∠C = 180°

40° + ∠B + ∠B = 180°

2 ∠B = 180° - 40°

2 ∠B = 140°

∠B = 140°/2

∠B = 70°

∠B = ∠C = 70°

Hence, the possible measures for ∠B and ∠C are 70°.
