I used a graphing calculator and calculated the t-interval of the jellybean sample using a 99% confidence level:
tInterval 9.68,1.23,125,0.99
It resulted in 9.68 ± 0.287805.
Therefore, we're 99% confident that the weight number of jellybeans would lie between 9.3922 oz and 9.9678 oz.
A weight of 9.45 oz lies within this range, therefore, it is possible that the candy company's claim is true.
Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Mean weight was 9.68 oz
standard deviation of 1.23 oz
n=125
µₙ=9.68
σₙ=1.23/√125
=0.11
Confidence level 99%
z=2.58
-z<x-µₙ/σₙ<z
9.68-2.58(0.11)<x<9.68+2.58(0.11)
9.3962<x<9.9638
9.45 is between this range
Fail to reject the null hypothesis. There is not enough evidence to oppose the companys claim.
Hence, Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.

What is the percent increase each year for the investment?
Answer:
11.5%.
Step-by-step explanation:
Looking at the base of the exponent, it can be seen that it is 1.115. 1.00 is equal to 100% of the investment value each year. There is an additional 0.115, which is equivalent to 11.5%, which represents the increase in the investment value each year.
Therefore, the percent increase each year for the investment is 11.5%.

A rectangle with an area of 3990 cm2 is x centimeters wide and (x+4) centimeters long. To the nearest tenth of a centimeter, the width and length are
Answer: width:60.2 cm
Length: 64.2 cm
Step-by-step explanation:
Given
The area of the rectangle is [tex]3990\ cm^2[/tex]
Width of the rectangle is [tex]x\ cm[/tex]
Length of the rectangle is [tex]x+4\ cm[/tex]
Area of the rectangle is the product of length and width
[tex]\therefore 3990=(x+4)x\\\Rightarrow 3990=x^2+4x\\\Rightarrow x^2+4x-3990=0\\\Rightarrow x=60.198\ or\ -65.198\ cm\\\text{Neglecting negative term}\\\Rightarrow x=60.198\approx 60.2\ cm[/tex]
Width of the rectangle is [tex]60.2\ cm[/tex]
Length of the rectangle is [tex]60.2+4=64.2\ cm[/tex]

Which function models the data in the table?
f (x) = StartFraction 1 Over x EndFraction, x not-equals 0
f (x) = log StartFraction 1 Over x squared EndFraction, x not-equals 0
f (x) = log StartFraction 1 Over x EndFraction, x not-equals 0
f (x) = StartFraction 1 Over x squared EndFraction, x not-equals 0
The best function that models the data is f(x) = log StartFraction 1 Over x EndFraction, x not-equals 0
Find the table attached below
From the table shown, we can see that when x = 1/10, f(x) = 1
Similarly when x = 1/100, f(x) = 2
According to the law of logarithm, we can say that:
Log 10 = 1
Log 100 = 2 etc..
Recall that f(x) = 1 when x = 1/10, this means that;
F(x) = log 10
F(x) = log(1/1/10))
F(x) = log(1/x) since x = 1/10
Similarly if f(x) = 2 when x = 1/100
F(x) = log 100
F(x) = log(1/1/100))
F(x) = log(1/x) since x = 1/100 in this case
On a general note, we can conclude that f(x) = 1/x where x is not equal to zero.

Find the slope of the line that passes through (23, -30) and (-7, 18).
Answer:
slope = - [tex]\frac{8}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (23, - 30) and (x₂, y₂ ) = (- 7, 18)
m = [tex]\frac{18-(-30)}{-7-23}[/tex] = [tex]\frac{18+30}{-30}[/tex] = [tex]\frac{48}{-30}[/tex] = - [tex]\frac{8}{5}[/tex]
x + y = −3
y = 2x + 2
Answer:
Step-by-step explanation:
x + y = −3
y = 2x + 2
Substitute the y value of the second equation into the top equation
x + 2x + 2 = - 3
3x + 2 = - 3
3x = -3 -2
3x = - 5
x = -5/3
x + y = - 3
-5/3 + y = - 3
y = -3 + 5/3
y = -1 1/3
The volume of a one is 80 cubic cm what is the volume of the cylinder with the same base and height of the cone
Answer:
240 cubic cm
Step-by-step explanation:
Volume of a cone = 1/3(nr^2h)
volume of a cylinder = nr^2h
n = 22/7
r = radius
The volume of a cone is 1/3 that of a cylinder
to determine the volume of the cylinder with the same parameters as a cylinder, multiply the volume of the cone by 3
80 x 3 = 240 cubic cm
