Answer:

Following are the complete solution to the given question:

Step-by-step explanation:

The Lower-limit of the Ist class: [tex]\$1[/tex]

The width of the class interval: [tex]\$200[/tex]

Lower-limit for the next five-class: [tex]\$201, \$401, \$601, \$801, \$1001[/tex]

Upper-limit for the next five-class: [tex]\$200, \$400, \$600, \$800, \$1000, \$1200[/tex]

For point a:

class intervals  

[tex]\$1-\$200\\\\ \$201-\$400\\\\ \$401-\$600\\\\ \$601-\$800 \\\\\$801-\$1000\\\\ \$1001-1200[/tex]

For point b:

Mid-points:

[tex]\$100.5\\\\\$300.5\\\\\$500.5\\\\\$700.5\\\\\$900.5\\\\\$1000.5\\\\[/tex]

Answer:

The correct answer is "0.43".

Step-by-step explanation:

According to the question,

The probability of boat accessories sale,

= 0.3

The probability of sale in Portland store,

= 0.35

now,

The probability that the decision was signed somewhere at Portland shop will be:

= [tex]\frac{P(boat \ acessories \ sale\times P(sale \ in \ Portland \ store)}{P(boat \ accessories \ sale)}[/tex]

By substituting the values, we get

= [tex]\frac{ 0.3\times 0.35}{( 0.2\times 0.5 + 0.3\times 0.35 + 0.25\times 0.15)}[/tex]

= [tex]\frac{0.105}{0.1+0.105+0.0375}[/tex]

= [tex]0.43[/tex]

Answer:

Tn = -4n²+40n+36

Step-by-step explanation:

A general quadratic sequence, Tn = an²+bn+c, where n is the term of the sequence.

So, when n = 1, Tn = 72, which means T1 = a+b+c=72.

when n = 2, Tn = 100, which means T2= 4a+2b+c = 100

when n = 3, Tn = 132, which means T3 = 9a+3b+c = 132.

Now, use a calcaulatot to solve the 3 variable simultaneous equation. According to my calculator, a = -4, b = 40, c = 36.

Hence, you a, b, and c in the Tn equation given above.

Therefore, Tn = -4n²+40n+36

Answer:

c. The interquartile range offers a measure of income inequality among California residents.

Step-by-step explanation:

The range is the midspread which measures statistical dispersion. This is also known as H-spread which is equal to the difference between 75th percentile and 25th percentile. In the given scenario the interquartile range offers measure of income inequality among California residents.

Answer:

  548 W

Step-by-step explanation:

The work done to raise 4 kg to a height of 12 m against gravity is ...

  W = Fd = Mgd = (4 kg)(9.8 m/s²)(12 m) = 470.4 J

The power output of the pump doing this work each second is ...

  P = (470.4 J)/s = 470.4 watts

Since the pump is only 86% efficient, the power input is ...

  Pout = eff × Pin

  Pin = Pout/eff

  Pin = (470.4 W)/(0.86) ≈ 548 W

_____

Additional comment

The rating of a motor often has little to do with its actual input power or its ability to do work. The rating is used for purposes such as circuit-breaker and wire sizing, or other aspects of sizing the physical plant surrounding the motor (including piping, in the case of a pump). While we can calculate a value for input power, we cannot make any claim regarding the power rating of the pump.

Answer:

  12°

Step-by-step explanation:

We assume you mean ...

  ∠x = 174°

Angle a is supplementary to angle x, so is ...

  ∠a = 180° -174° = 6°

Angle b is a vertical angle with respect to angle 'a', so is the same measure.

  ∠a +∠b = 6° +6° = 12°

Answer:

0.8 = 80% probability that they did in fact study for the test.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Passed the exam.

Event B: Studied.

Probability of passing the test:

80% of 60%(Studied).

30% of 100 - 60 = 40%(did not study). So

[tex]P(A) = 0.8*0.6 + 0.3*0.4 = 0.6[/tex]

Probability of passing the test studying:

80% of 60%, so:

[tex]P(A \cap B) = 0.8*0.6 = 0.48[/tex]

Find the probability that they did in fact study for the test with this knowledge in hand.

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.48}{0.6} = 0.8[/tex]

0.8 = 80% probability that they did in fact study for the test.

Answer:

  the correct choice is marked

Step-by-step explanation:

The process for completing the square would generally put x-terms on one side of the equal sign and the constant term on the other side:

  x^2 +4x = 3

Then the square of half the x-coefficient would be added to both sides. Here, that is (4/2)^2 = 4.

  x^2 +4x +4 = 7

In order to make this match one of the answer choices, we must multiply both sides by 4.

  4x^2 +16x +16 = 28

Now, we can factor the left side to see a match to the last answer choice.

  (2x +4)^2 = 28

_____

Additional comment

As you can see, we had to deviate from the "complete the square" process to arrive at an equation that matches an answer choice. It cannot be said that the chosen equation "is used in the process." It might be useful to discuss this question with your teacher.

Answer:

x = 25 , x = 136

Step-by-step explanation:

(15)

The opposite angles of a cyclic quadrilateral are supplementary , sum to 180°

3x + 105 = 180 ( subtract 105 from both sides )

3x = 75 ( divide both sides by 3 )

x = 25

(16)

The chord- chord angle is half the sum of the arcs intercepted by the angle and its vertical angle, then

x = [tex]\frac{1}{2}[/tex] (VW + UX) = [tex]\frac{1}{2}[/tex](115 + 157) = [tex]\frac{1}{2}[/tex] × 272 = 136

V = 4/3 ( 3.14) ( 8)^3

V = 2143.57333 cm^3

Rounding to the nearest hundredth

V = 2143.57 cm^3

Answer: 2,143.57

Step-by-step explanation: because the formula to do it is the use the radius and search up the sphere formula and do it

Answer:

0.1487

Step-by-step explanation:

From the table :

The total number of people living alone in the region = 31.6

The number of people living in the region who fall with the 25 - 34 age range is 4.7

Probability, P = required outcome / Total possible outcomes

P(range 25 - 34) = (number of people who fall within the 25 - 34 age range) / total population

P(range 25 - 34) = 4.7 / 31.6 = 0.1487

D. Highest increase in the multiple R2.

Step-by-step explanation:

Included variables in a multiple regression model are those variables which have the most effect on the model ; variables which have no effect on the performance of the model ar discarded. Model performance are based on the variables affect the multiple R² value of the model. The R² value is the coefficient of determination which gives the proportion of change in predicted value based on the regression line. Higher R² value means the variable has greater effect in the model performance. Therefore, variables which have the highest increase on the multiple R² value , are included.

Answer:

  4%

Step-by-step explanation:

The simple interest formula can be used.

  I = Prt

where r is the annual rate and t is the number of years.

 1/5 = 1·r·5

 (1/5)/5 = r = 1/25 · 100% = 4%

The rate is 4%.
