Answer:

b=$65

Step-by-step explanation:

From question:

Four friends went out to dinner

Decided to equally split the bill

Each paid 16.25

(a)Total amount = b

Average amount paid by 4 friends =16.25

b = Average amount*total number of friends

= 16.25 * 4

(b) b= 4*16.25

=65

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 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.

Step-by-step explanation:

1. 16x - 16 = 4(4x-4)

2. 16x - 16 = 16x - 16

3. 0 = 0

Answer:

D. -93/20

Step-by-step explanation:

-6/5 is -1.2 in decimal form so then you multiply -1.2 by 3.875 and get -4.65, convert that into a fraction and get -93/20.

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.

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:

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:

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

Answer:

x = 25º, right scalene triangle

Step-by-step explanation:

The interior angles of a triangle add up to 180º.

The red square indicates the angle measure is 90º.

We are left with two other angles, x and (2x + 15).

Let's set up an equation to represent the angle measures

90 + x + (2x + 15) = 180

First, combine like terms.

90 + x + 2x + 15 = 180

105 + 3x = 180

Subtract 105 from both sides to isolate x.

3x = 75

Divide both sides by 3 to further isolate x.

x = 25º

Let's check our answer by plugging it back into our original equation.

90 + x + (2x + 15) = 180

90 + 25 + (2(25) + 15) = 180

Simplify.

90 + 25 + (50 + 15) = 180

90 + 25 + 65 = 180

115 + 65 = 180

180 = 180

Your answer is correct.

x = 25º

Now we need to classify the triangle.

As stated before, the red square indicates the angle measure is 90º. This means our triangle is a right triangle.

Because the other two angle measures are different from one another, we know that the side measures cannot be equal. This leaves us with a scalene triangle.

Your answer is: right scalene triangle

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
