The sample size must be large enough to support an assumption that the sampling distribution of the sample proportion is approximately normal. Therefore, the correct answer is option is C.

In order to use the normal approximation, we consider both np and n( 1 - p ). If both of these numbers are greater than or equal to 10, then we are justified in using the normal approximation.

While conducting a one-sample test, the population proportion is taken as p and the given sample size is n.

For the sample data to be used for the normal approximation

n×p≥10 and

n(1-p)≥10

Condition should be met.

That means when the np and n(1-p) value is greater than 10, the entire sample can be said to behave like a normal distribution.

This can be regarded as a general rule of thumb, and typically the larger the values of np and n(1-p), the better is the approximation.

Therefore, the correct answer is option is C.

Answer: 1200 pennies

Step-by-step explanation:

Let x be the number of pennies Yoko's bank can hold.

We can set up an equation representing the information given.

[tex]\frac{2x}{5} + 320 = \frac{2x}{3}[/tex]

We can multiply both sides by 15:

6x + 4800 = 10x

Combine like terms:

4x = 4800

Divide both sides by 4:

x = 1200

Answer:

5

Step-by-step explanation:

We know the formula for area (for triangles) is: 1/2bh.

We can write the equation 10=1/2(4)(h). 1/2*4 = 2, so 10=2h. Divide 2 from both sides, and we get 5.

The equations that can be used to determine the original price of the laptop are p (1 + 0.32) = $1,137.84 and $1,137.84 = 1.035p

Markup is when the price of an item is increased by a certain percentage. The cost of the laptop was increased by 32%.

The price of the laptop after the increase = p(1 + percentage increase)

p (1 + 0.32) = $1,137.84

$1,137.84 = 1.035p

Answer:

x = -3, y = 24

Step-by-step explanation:

y=−7x+3;y=−8x

Step: Solve y=−7x+3 for y:

y=−7x+3

Step: Substitute−7x+3 for y in y=−8x:

y=−8x

−7x+3=−8x

−7x+3+8x=−8x+8x(Add 8x to both sides)

x+3=0

x+3+−3=0+−3(Add -3 to both sides)

x=−3

Step: Substitute−3 for x in y=−7x+3:

y=−7x+3

y=(−7)(−3)+3

y=24(Simplify both sides of the equation)

Answer:

  1:  y = 2x -4

Step-by-step explanation:

The perpendicular bisector of the given segment is the line through its midpoint that has a slope that is the opposite reciprocal of the segment's slope.

The slope of the given segment can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (6 -2)/(0 -8) = 4/-8 = -1/2

The opposite reciprocal of this is ...

  m' = -1/(-1/2) = 2 . . . . (eliminates answer choices 2 and 3)

__

The midpoint of the given segment is ...

  (A+B)/2 = (8 +0, 2 +6)/2 = (4, 4)

__

The y-intercept of the perpendicular bisector can be found from ...

  b = y -mx

  b = 4 -(2)(4) = -4

Then the equation of the perpendicular bisector is ...

  y = 2x -4

Answer: (5a+b)/2

Step-by-step explanation:

1. First factor 5a^2+36ab+7b^2

=(5a+b)(a+7b)

2. Factor 2a+14b

The two can be factored out, making the equation equal to 2(a+7b).

The factored out equation is now [tex]\frac{(5a+b)(a+7b)}{2(a+7b)}[/tex]

Since there is an (a+7b) on both sides of the fraction, they cancel out. You are left with (5a+b)/2. This fraction cannot be simplified more.

To verify you can multiply (5a+b)/2 times (2a+14b). If it is correct, it should come back out as 5a^2 + 36ab +7b^2

Given: The Table of Values

To Find: The least-squares regression line for the data set in the table by using the desmos graphing calculator.

SolutionThe general form of least-squares regression line is: y = mx + b Where, m is the slope and b is the y-intercept.

Where, m is the slope and b is the y-intercept.By using the desmos graphing calculator, we get

m 2.55 b -6.435 Substitute these Values

y = (2.55)x + (-6.435)

y = 2.55x - 6.435

Answer: A

The expression to generate the parameters and statistics is y tilde m x plus b, the correct option is C.

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that;

x subscript 2 baseline y subscript 2 baseline;

1 2

2 9

3 7

4 12

Now,

To find the least-squares regression line for a data set using Desmos, you need to follow these steps:

Enter the data as a table in Desmos. For example, type {1, 2, 3, 4} in the x column and {2, 9, 7, 12} in the y column.

Type y tilde m x plus b in the expression box. This tells Desmos to find the values of m and b that minimize the sum of squared errors between y and y tilde (the predicted values).

Click on the wrench icon next to the expression to see the parameters and statistics. You should see something like this:

m = 2.8 b = -1.6 r² = 0.84

This means that the equation of the least-squares regression line is:

y tilde = 2.8 x - 1.6

And that the coefficient of determination (r²) is 0.84.

Therefore, by expression the answer will be y tilde m x plus b.
