Answer:

not number 5 is is biased.

Number 6 is not biased.

Number 7 is not biased.

Step-by-step explanation:

Biased means of an estimator is the difference between this estimator's expected value and the true value of the parameter being estimated.

Answer:A

Step-by-step explanation: use algebra to find the value in the absolute value symbols which is 10/3. Then multiply that by -1 which gets you -10/3. Then multiply -10/3 with the reciprocal of 5/6 which gets you -4

Answer:

128.74

Step-by-step explanation:

.8x = 120.00

.87x = 112.00

This represents an easier way to do the problem if there is 20% off that means you are paying 80% of the original cost. You are paying 87% if it is 13% off.

To find the price at nine-irons divide 112 by .87

20% of 120 is 24

120 - 24 = 96

96 - 8 = 88

13% of 100 is 13

100 - 13 = 87

Answer:

I can only help you with Part C and E as these two are the ones I am able to answer.

Part C: slopes are not the same

Part E:  195 yards

Step-by-step explanation:

Part C:

Part E: The slope of the line follows a linear pattern; therefore, find the equation for the line by calculating the slope and plugging in a point.

Slope:

y2-y1/x2-x1; (9, 105) (8,115)

(115-105)/(8-9) = -10; the slope is -10, now solve for the equation of the line.

y=mx+b; plug in the point (9,105)

105 = -10(9) +b

105 = -90 +b, add 90 to both sides

195 = b; rewrite the equation;

y=-10x+195; x stands for the iron, plug in 0 for x;

y=-10(0)+195

y=195 yards.

Answer:

A  The scatter plot that matched the data is the second scatter plot while the first scatter plot wrongly represents the data because values of the Iron not present in the data is also represented in the scatter plot and also some values present in the data table is also missing in the First scatter plot.

B  The scatter plot describes the strong negative association because in the scatter plot strong downhill linear relationship.

C  In mathematics the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is denoted by the letter m in the equation of a straight line "y = mx + c".

D  195 yards

Step-by-step explanation:

To find the slant height of triangular faces: The slant height of a triangular pyramid is generally represented by 's'. Add all the areas together. Thus, the surface area of a triangular pyramid formula is 1⁄2(a × b) + 3⁄2(b × s) in squared units.

The surface area of this triangular pyramid is 10.908 in².

We have,

Base of Triangle= 3 in

Height of Triangle= 3 inch

P = 3 inch

h = 4 inch

Now, slant height= √4² + 1.5² = √16+2.25 = 4.272 inch

So, the Surface Area of Triangular Pyramid

= base Area + 1/2 x 3 x 4.272

= 1/2 x 3 x 3 + 6.408

= 4.5 + 6.408

= 10.908 in²

Thus, the surface area of this triangular pyramid is 10.908 in².

Step-by-step explanation:

1.Since opening night, attendance at Play A has increased steadily, while attendance at Play B first rose and then fell. Equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. On what day(s) was the attendance the same at both plays? what was the attendance?

Play A: y=7x+84

Play B: y=-x^2+40x-6

A. The attendance was the same on day 30. The attendance was 294 at both place that day.

B.The attendance was the same on day 3. The attendance was 105 at both place that day.

C. The attendance was never the same at both plays

D. The attendance was the same on days 3 and 30. The attendance at both plays on those days was 105 and 294 respectively.

Answer:

x = 8.36

Step-by-step explanation:

First, subtract 4.6 from both sides of the equation, then just simplify.

Answer: x = 8.36

(same thing as 209/25)

Step-by-step explanation:

Move the constant to the right hand side and change its sign.

x = 12.96 - 4.6

Subtract the numbers.

x = 8.36

Answer:

399 children, 33 adults

Step-by-step explanation:

Children = c

Adults = a

c + a = 432

a = 432 - c

1.5c + 2a = 664.50

1.5c + 864 - 2c = 664.50

-.5c + 864 = 664.50

-.5c = -199.5

.5c = 199.5

c = 399

432 - 399 = 33

a = 33

Answer:

kids = 399

adults = 33

They are 2 units apart from each other

Answer:

A since if we multiply 4 × 4x, we get 16x, and 4 × 4, we get 16, which cancels with the other 16x - 16 on the left side. That makes sure that any x we choose will cancel out in the end.
