Answer: Required 99% confidence interval  : (48.30%, 61.7%)

Step-by-step explanation:

Confidence interval for PROPORTION:  [tex]p\pm z^* \times S.E.[/tex], where p = sample proportion , z* = two-tailed critical z-value  and S.E. = standard error.

As per given: p=55%

Critical z-value for 99% confidence = 2.576

S.E. = 2.6%

Then, required confidence interval :

[tex]55\% \pm (2.576)\times 2.6\%\\\\\approx55\% \pm6.70\%\\\\=(55\%-6.70\%,\ 55\%+6.70\%)\\\\=(48.30\%,\ 61.7\%)[/tex]

Required 99% confidence interval  : (48.30%, 61.7%)

Answer:   30%

Step-by-step explanation:

Pie eaten by Anita = 30%

Pie eaten by Bob = 40%

total Pie = 100%

Pie left for by Sheila = 100 - (30 + 40)

                                 =  100 - 70

                                  = 30%

therefore, pie left for Sheila = 30%

Answer:70%

Step-by-step explanation:

Given:

Consider angle S is congruent to angle U.

The angle S is (5x-11) degrees and angle U is (4x+9) degrees,

To find:

The value of x.

Solution:

Since it is given that angle S is congruent to angle U, therefore the measure of theses two angles are equal because measure of congruent angles are equal.

[tex]m\angle S=m\angle U[/tex]

Put the given values.

[tex]5x-11=4x+9[/tex]

Subtract 4x from both sides.

[tex]5x-4x-11=9[/tex]

Add 11 on both sides.

[tex]x=9+11[/tex]

[tex]x=20[/tex]

Therefore, the value of x is 20.

Answer: 1/3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Assuming the table attached with C in inches and S in pounds, we see that the first differences in S are ...

  180, 540, 900

These are not constant, so the relation is not linear.

Second differences are ...

  360, 360

These are constant, so the relation is quadratic. With a short trial, we find that a suitable equation is ...

  S = 180·C²

__

The safe load for C=10 is then ...

  S = 180·10² = 18,000 . . . pounds

Answer:

Rebecca's overtime rate is $20.25 per hour

Step-by-step explanation:

Rebecca is paid $13.50 per hour as her regular wage.

Her boss pays her that amount and a half for overtime work.

Half of her regular pay rate is 13.50/2= $6.75

Thus, her overtime rate is:

$13.50 + $6.75 = $20.25

Rebecca's overtime rate is $20.25 per hour

Answer:

$33.28

Step-by-step explanation:

8.7 times 3.25 is 28.275

28.275 + 5 = 33.275

33.275 rounded to the nearest coin is 33.28

Answer:

$33.28

Step-by-step explanation:

So, we would multiply $3.25 by 8.7 miles.

$3.25 · 8.7 = $28.28

Then we would add on the additional $5.00

$28.28 + $5.00 = $33.28

[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

For this, we shall use the slope formula:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]      ← this is  [tex]\frac{rise}{run}[/tex]

Assuming this is a line, all we do is pick two consecutive points and plug them in. For example, let's take the first two points. (1, -4) and (7, 5) as they are the easiest to work with.

Let's plug in these two values:

[tex]\frac{5 - (-4)}{7 - 1}[/tex]

Simplified we get:

[tex]\frac{9}{6}[/tex]

We are now able to factor 3 out of the numerator and denominator:

[tex]\frac{3}{2}[/tex]

Thus resulting in the slope.

Answer:

Step-by-step explanation:

The linear equation y = -2x is passing through the origin. Then the correct option is B.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

y = -2x

The y-intercept in the above equation is zero. Then the linear equation is passing through the origin.

The linear equation y = -2x is passing through the origin. Then the correct option is B.

The midpoint of a line segment is the point equidistant to the endpoints of the line. The coordinate of S is (2,-9)

Given that:

[tex]T(x_1,y_1) = (0,5)[/tex]

[tex]M = (1,-2)[/tex] --- the midpoint of ST

[tex]S = (x_2,y_2)[/tex]

To calculate the coordinates of S, we use the following midpoint formula:

[tex]M = 0.5 \times (x_1 + x_2,y_1+y_2)[/tex]

So, we have:

[tex](1,-2) = 0.5 \times (0 +x_2,5 + y_2)[/tex]

Divide both sides by 0.5

[tex](2,-4) = (0 +x_2,5 + y_2)[/tex]

[tex](2,-4) = (x_2,5 + y_2)[/tex]

Compare both sides

[tex]x_2 = 2[/tex]

[tex]5 + y_2 = -4[/tex]

Collect like terms

[tex]y_2 = -4-5[/tex]

[tex]y_2 = -9[/tex]

Hence, the coordinates of S is:

[tex]S = (2,-9)[/tex]

Answer:

the answer is #3

Step-by-step explanation:

the expression that represents C, the total cost of her ride, in terms of m, the length of the trip in miles is C = 5 + 0.25m.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given this, Maria took a taxicab from her home to the theater downtown. The taxicab company charges a flat fee of $5.00 plus $0.25 per mile.

Since, C represents the total cost of her ride, in terms of m, the length of the trip in miles.

So,

Total cost = fixed cost + variable cost

In our case

Fixed cost = 5

and the variable cost = 0.25 per mile

For m miles variable cost = 0.25*m

Thus,

Total cost = 5 + 0.25*m

C = 5 + 0.25m

therefore, the expression that represents C, the total cost of her ride, in terms of m, the length of the trip in miles is C = 5 + 0.25m.

Answer:

C: 12 or 20 feet from the edge

Step-by-step explanation:

We are told the recommended height is 18 feet and that the function describing the height is;

h(x) = -(3/2)|x - 16| + 24

This means that;

-(3/2)|x - 16| + 24 = 18

Multiply through by -2/3 to give;

|x - 16| + 24(-2/3) = 18(-2/3)

|x - 16| - 16 = -12

Add 16 to both sides to get;

|x - 16| = 16 - 12

|x - 16| = 4

Add 16 to both sides to get;

Expanding the absolute value problem, we have;

x - 16 = 4 or -(x - 16) = 4

Thus;

x = 16 + 4 or -x + 16 = 4

x = 20 or x = 16 - 4

x = 20 or x = 12

Since x is the distance along the width of the house, then Terry should place the dish 12 or 20 feet from the edge
