A recent article published in Berry Weekly reported a probability distribution for the different types of jelly that
individuals prefer. Editors from a competitive magazine, Jammin, conducted their own study to test the
distribution. The editors from Jammin surveyed a random sample of 50 individuals and recorded the observed
counts of individuals for each jelly type. They decided to test Berry Weeklys claim using a chi-square goodness-
of-fit test using Jammin's observed counts compared with the number of expected counts based on the Berry
Weekly data.

A cone has a diameter of 20cm and a height of 12cm, what is the volume of the cone?
Answer:
The cone volume that has a diameter of 20cm and a height of 12cm is 5,026.548246 cm^3 or 5,027 cm^3
Make sure to round your answer to the nearest significant figure that you're asked.
Step-by-step explanation:
The formula for the volume of a cone is (height x π x (diameter / 2)^2)/3, where (diameter / 2) is the radius of the base (d - 2 x r), so another way to write it is (height x π x radius^2) / 3
You have recently signed up for a new job and noticed this policy for retirement savings. Invest $200 and the employer does 70% matching for 35 years at an interest rate of 4.8%.
Find the total amount that the employer contributes each month.
What amount will you have after 35 years?
How much money have you deposited into the account yourself?
How much more money is in the account than what you have deposited?
Answer:
Amount per month contributed by employer $ = 200*0.70 = 140
Total amount employer contributes $ = 140*420 = 58800
Total amount employee contributes $ = 200*420 = 84000
Total amount after 35 years with interest calculated AT 4.8% (Employer + employee + interest) $ = 371024.67
Interest amount for 35 years accumulated $ = 228224.67
Amount deposited by employee $ = 84000
Excess amount in the account over the employee contribution
Including employer contribution $ = 287024.67
Excluding employer contribution $ = 228224.67

it's not possible
I think -7 is the right answer but it's not possible actually
Answer:
c. -7
Step-by-step explanation:
(x+57) + (63+67) = 180
(x+57) + 130 = 180
x + 187 = 180
x = 180-187
x = -7
why did I make it equal to 180?
all the angles in a triangle always equal 180 :)
PLEASE HELP !! ILL GIVE BRAINLIEST !!
Answer:
117
Step-by-step explanation:
angle 2 = 117 so angle 1 has to =63 because they have to equal 180 (supplementary angles)
angle 1 =63 . angle 3 =117
angle 7 is the same measurement of angle 3
hope this makes sense
Answer:
117 degrees
Step-by-step explanation:
angle 1 and 2 are supplementary angles which are angles whose measurements add up to 180 degrees
this means angle 1 = 63 degrees
63 + 117 = 180
angle 1 and 3 are linear pair angles which means they also equal 180 degrees
angle 3 = 117 degrees
angle 3 and angle 7 are corresponding angles which means their degrees are equal to each other
angle 7 = 117 degrees
The relationship between angle 2 and 7 would be alternate exterior angles
Help with the calculus problem please
The area of the region is equal to the area under the curve y = cos(x) over the interval 0 ≤ x ≤ π/6, given by the integral

Which missing piece of information would allow the triangles in the figure to be proven congruent by AAS?
The missing piece of information is ∠C ≅ ∠C′
How to determine the missing piece?From the figure, we have:
AB ≅ A'B'
<B ≅ <B'
The above means that:
Sides AB and A'B' are congruentAngles B and B' are congruentThe congruence theorem is given as:
AAS --- Angle Angle Theorem
i.e.
Two corresponding angles and one corresponding side are congruent
Since a congruent side and a congruent angle have been given;
We need a congruent angle to complete the piece
In this case, we have:
∠C ≅ ∠C′
Hence, the missing piece of information is ∠C ≅ ∠C′

Answer:
3) b = 2.24
4) c = 15.62
Step-by-step explanation:
Pythagorean formula:
a² + b² = c²
3)
a² + b² = c²
2² + b² = 3²
4 + b² = 9
b² = 5
b = 2.24
4)
a² + b² = c²
10² + 12² = c²
100 + 144 = c²
244 = c²
c = 15.62
An aquarium 4 m long, 1 m wide, and 1 m deep is full of water. Find the work needed to pump half of the water out of the aquarium. (Use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3). Show how to approximate the required work by a Riemann sum.
Express the work as an integral.
Evaluate the integral.
Answer:
Workdone = 4900joules
Step-by-step explanation:
Work-done = force x distance
Force = mass x acceleration
If we suppose that the aquarium is at height 0 at the top and height 1 at the bottom (since it's 1m deep), then we need to lift the slide at height x by x metres.
Mass = Density x Volume, therefore force needed to lift the slice is given is
F = density*volume*∆x*acceleration
Since we the mass changes as we take out water then there will be a change in height, for this reason we have ∆x.
Acceleration is due to gravity, therefore g=9.8m/s²
Density = 1000kg/m³
Volume = 4*1*1 = 4m³
F = 1000*4*∆x*9.8 = 39200∆x
Since our distance from the top of the aquarium to the bottom is x metres, then
Work-done = 39200x∆x
To find the total workdone, we find the integral of 39200xdx and the limit will be from 0 to 0.5 since we are to pump halfway of the aquarium. Integrating that we have
19600*x² limit from 0 to 0.5
19600(0.5² – 0²) = 19600(0.25 – 0) = 19600(0.25) = 4900joules

What is the length of de
Answer:
B. 37 units
Step-by-step explanation:
DE = 4x + 1
AB = 11x - 25
DE is a midsegment of the ∆ABC
Therefore:
DE = ½(AB) => Triangle Midsegment Theorem
4x + 1 = ½(11x - 25)
2(4x + 1) = 11x - 25
8x + 2 = 11x - 25
Collect like terms
8x - 11x = -2 - 25
-3x = -27
-3x/-3 = -27/-3
x = 9
✔️DE = 4x + 1
Plug in the value of x
DE = 4(9) + 1 = 36 + 1
DE = 37
Find the magnitude and direction of the vector r=(-4 6)
Step-by-step explanation:
The given vector is :
r = (-4,6)
We can write in the form of vector as follows :
r = -4i+6j
The magnitude of vector r is :
[tex]|r|=\sqrt{-4^2+6^2} \\\\=\sqrt{16+36} \\\\=7.21[/tex]
For direction,
[tex]\tan\theta=\dfrac{y}{x}\\\\\theta=\tan^{-1}(\dfrac{y}{x})\\\\=\tan^{-1}(\dfrac{6}{-4})\\\\=-56.3^{\circ}[/tex]
So, the magnitude is 7.21 and the direction is [tex]-56.3^{\circ}[/tex]
