A salesman at a clothing store makes a sale to 30% of the customers he talks to, and wants to try out a new tecnique to see if he can change this rate. He decides to collect data for a few months on the percentage of customers he makes a sale to, and he is able to construct a 95% confidence interval of (.3095, .3275). Is there evidence at 5% significance that he has changed his average sales?
Answer:
Yes, we can conclude that average sales has changed.
Step-by-step explanation:
The null hypothesis, H0 : μ = 0.3
The alternative ; H0 : μ ≠ 0.3
The result of the 95% confidence interval of (.3095, .3275); This shows that the confidence interval is now between 30.95% and 32.75% ; since μ does not lie within the confidence interval value and the lower boundary of the confidence interval is > 30; we Can conclude with an evidence of 5% significance that his average sales as changed (increased).
We can reject H0 and conclude that μ > 0.3

The height of the mural drawing is 9 inches while the length is 101.25 inches.
What is the scale factor?You must specify the extent of the shape's enlargement when describing one.
The scale factor is the ratio of two dimensions such that one figure is large and another is small.
The scale factor is done due to the unpractical measurement of any figure.
Hight of the mural = is 12 feet
⇒ 12 × 12 = 144 inches.
Length of mural = 135 feet
⇒ 1620 inches.
Now,
She is using 3 cm for every 4 feet(4×12 = 48 inches)
Scale factor = 3/48 = 1 : 16
Now,
Length of mural drawing = 144/16 = 9 inches.
Height of mural drawing = 1620/16 = 101.25 inches.
Hence "The height of the mural drawing is 9 inches while the length is 101.25 inches".

70 as a fully simplified ratio.
Answer:
3:7
Step-by-step explanation:
To simplify the ratio 30:70, we find the greatest common divisor of 30 and 70, and then we divide 30 and 70 by the greatest common divisor. The greatest common divisor that you can use to simplify 30:70 is 10. This means the answer to ratio 30:70 simplified is: 3:7.

Dave drives a truck and can only drive 35 miles per day. If he drives 1,960 miles and gets paid $18 per day, how much money will he make?
Answer: $1008
Step-by-step explanation:
Since Dave can only drive 35 miles per day and he drives 1,960 miles, this means that the number of days he used for driving will be:
= 1960 / 35
= 56 days
Since he gets paid $18 per day, the amount that he will make will be:
= $18 × 56
= $1008

The length of a rectangle is 1 yd more than twice the width, and the area of the rectangle is 45 yd2 . Find the dimensions of the rectangle. Length : Width :
Answer: length = 10 yards
Width = 4.5 yard
Step-by-step explanation:
Let the width be represented by x.
Since the length of a rectangle is 1 yd more than twice the width. This will be:
= (2 × x) + 1
= 2x+1
Area = 45
Note that length × breadth = Area
(2x + 1) × x = 45
2x² + x = 45
Equate the equation to 0
2x² + x - 45 = 0
2x² + 10x - 9x - 45 = 0
2x(x + 5) - 9(x + 5) = 0
(2x - 9) = 0
2x = 9
x = 9/2
The width is 4.5 yard
Length = 2x + 1
= 2(4.5) + 1
= 9 + 1
= 10 yard
Buffalo Chicken Dip calls for ¾ cup of buffalo sauce and serves 12 people. If I am having 30 people over for a party, how much buffalo sauce will I need for my recipe?
Answer:
15/8 cup or [tex]1\frac{7}{8}[/tex] cup
Step-by-step explanation:
3/4 = 0.75
Ratios:
[tex]\frac{0.75}{12} =\frac{x}{30} \\\\12x=22.5\\x= 15/8[/tex]
Answer:
[tex]\frac{15}{8}[/tex] cup
This can also be expressed as the following:
[tex]1\frac{7}{8}[/tex] cup
Step-by-step explanation:
This problem involved ratios. A ratio is a way of expressing one value compared to another when the two values being compared are of a different unit. The problem gives one the general ratio of the following,
[tex]sauce (cups) : people (number)[/tex]
Substitute in the given values, since one knows the units, it is unnecessary to write it,
[tex]\frac{3}{4}:12[/tex]
In this problem, the ratio of cups of sauce to people is constant, therefore one can say that the amount of sauce that (12) people need is proportional to the amount of sauce that (30) people need. Thus, set up an equation to solve for the unknown amount of sauce that (30) people need. Let parameter (x) represent the unknown amount of sauce.
[tex]\frac{3}{4} : 12 = x : 30[/tex]
Use cross products to simplify,
[tex](12)(x)=(\frac{3}{4})(30)[/tex]
Simplify,
[tex]12x=\frac{45}{2}[/tex]
Inverse operations,
[tex]12x = \frac{45}{2}[/tex]
Multiply both sides by (2)
[tex]24x=45[/tex]
Divide both sides by (24),
[tex]x=\frac{45}{24}[/tex]
Simplify,
[tex]x=\frac{15}{8}[/tex]

If the answers to a quadratic equation were 2+6√3 and 2-6√3, then what was the original polynomial
Answer:
[tex] p(x) = k[ x^2-4x-104] [/tex]
Step-by-step explanation:
Say if alpha and beta are the zeroes of the quadratic polynomial then the quadratic polynomial is given by ,
[tex]\implies p(x) = k[x^2-(\alpha+ \beta)x +\alpha\beta ] [/tex]
where k is a constant[tex]\implies p(x) = k[ x^2 - [ (2+6\sqrt3)+(2-6\sqrt3)x] + \{ (2+6\sqrt3)(2-6\sqrt3)\} ] \\\\\implies p(x) = k[ x^2 - 4x + \{ (2)^2-(6\sqrt3)^2\}] \\\\\implies p(x) = k[ x^2 -4x \{ 4-108\} ] \\\\\implies\boxed{\boxed{ p(x) = k[ x^2-4x-104] }}[/tex]

A container at the petting zoo holds 8138.88 cubic centimeters of grain. Visitors can fill paper cones with with grain from the container. The cones have a radius of 4 and a height of 9.
Answer:
The volume of the container is = 8138.88 cubic centimeters
Radius of the cone = 4 cm
Height of the cone = 9 cm
Volume of the cone =
So putting the values as pi=3.14 , r=4 and h=9 we get
= 150.72 cubic cm
So, the number of times the cone can be filled is =
The number of times is = 54.
Step-by-step explanation:
54 is your answer
54 times can a cone fill with the grain that is stored in the container.
What is volume of cone?The formula for the volume of a cone is V=1/3hπr².
Given:
volume of the container is = 8138.88 cm³
Radius = 4 cm
Height = 9 cm
Volume of the cone =1/3*π*r²*h
=1/3*3.14*4*4*9
= 150.72 cm³
Thus, the number of times the cone can be filled is.
=volume of the container/Volume of the cone
= 8138.88 cm³/ 150.72 cm³
=54
Hence, 54 times can be filled.
