The alternative hypothesis
[tex]H_1:p \neq 0.64[/tex]
At 0.02 level of significance,
the testing firm rejects the null hypothesis.
This implies that the rejection of the null hypothesis shows that there is sufficient evidence to reject a newsletter publisher who believes that 64% of their readers own a Rolls Royce.

What is the total area, in square inches, of the shaded sections of the trapezoid below?
Help test
Total area of shaded region in trapezoid is 54.4in²
What is trapezoid?A trapezoid is a four-sided, quadrilateral shape with two parallel sides, which are called the bases, and two non-parallel sides, which are called the legs.
here, we have,
The formula for the area of a trapezoid is:
Area = (1/2) × (sum of the bases) × (height)
The Shaded region in trapezoid form right angled triangle.
Area of 1st shaded region=area of right triangle
=1/2×b×h
=1/2×6.8×7.4
=25.16in²
Area of 2nd shaded region=area of right triangle
=1/2×b×h
=1/2×6.8×8.6
=29.24in²
Hence, total area of shaded region in trapezoid is 54.4in²

cards: 37 through 80
Answer: a) and b)
Step-by-step explanation: Lets find the percentages for each option.
a). with 1-11 without 12-20
Here there are 20 shopers. From 1 to 11, there are 11 shoppers. From 12 to 20, there are 9 shoppers. 11 of 20 have credit cards, and 11/20 = 0.55. So this option is correct
b). with 1-33 without 34-60
Here there are 60 shoppers. 1 to 33 there are 33 shoppers with store credit cards. 33/60 = 0.55. So this is also a simulation which represents this situation.
c). with 1-24 without 25-40
Here there are 40 shoppers. 1 to 24, so there are 24 shoppers with the store credit card. 24/40 = 0.6. So this is not a correct option.
d). with 1-21 without 22-40
Here there are 40 shoppers, of which 21 have the credit card. 21/40 = 0.525, so this is not one of the options
e). with 1-18 without 19-40
Here there are 40 shoppers, of which 18 have the credit card. 18/40 = 0.45, so this is not one of the options.
f). with 1-36 without 37-80
Here there are 80 shoppers, of which 36 have the credit card. 36/80 = 0.45,
so this is not one of the options.

A multiplier of 1.641 corresponds to a percentage increase or decrease of what percent?
Answer:
A multiplier of 1.641 corresponds to a percentage increase or decrease of 64.1%.
Step-by-step explanation:
To determine a percentage increase or decrease of a certain number, a calculation consisting of the multiplication of said number by 1 plus the decimals corresponding to the percentage to be increased must be performed. Thus, for example, if you want to increase a number by 50%, you must multiply that number by 1.50. Therefore, if you multiply a number by 1,641, this implies that you are wanting to increase or decrease the initial number by 64.1%.

Determine if the statement is true or false. A system in echelon form can have more variables than equations. True False
Answer:
True.
Step-by-step explanation:
A system of a mathematical expression such as a matrix is said to be in echelon form when it has many variables.
There are two (2) forms of echelon matrices and these includes;
I. Reduced row echelon form (RREF)
II. Row echelon form (REF)
Hence, a system in echelon form can have more variables than equations.

Use the scale factor from Part I and a proportion to find the length of RT. Show your work.
Similar triangles are those triangles whose corresponding sides are in the same ratio. The length of the sides ST and RT are 5 units and 3 units, respectively.
What are similar triangles?Similar triangles are those triangles whose corresponding sides are in the same ratio. And the corresponding angles measure the same. It is denoted by ‘~’ symbol.
Given that the two triangles are similar because the two have the same ratio. Therefore, the ratio of the corresponding sides in the triangle can be written as,
Ratio = AB/RS = BC/ST = AC/RT
Ratio = 18/6 = 15/ST = 9/RT
Now, using the ratio the length of the sides can be written as,
18/6 = 15/ST
ST = (15 × 6)/18
ST = 5 units
18/6 = 9/RT
RT = (9 × 6)/18
RT = 3 units
Hence, the length of the sides ST and RT are 5 units and 3 units, respectively.

What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The height of the triangle will be 12 units and the base of the triangle will be 21 units. Then the area of the triangle is calculated as,
A = 1/2 x 21 x 12
A = 21 x 6
A = 126 square units
Thus, the correct option is D.
