Consider the population of four juvenile condors. Their weights in pounds are : 5, 6, 10, 13
Answer:
The unique weights are 5, 6, 10 and 13
Step-by-step explanation:
Given
Weights: 5, 6, 10, 13 pounds
Required
Determine the unique weights of the juvenile
From the question, we understand that the weights of the juveniles could be any of 5 pounds, 6, 10 or 13 pounds
These values are the unique weights of the juveniles.
In other words, any value other than 5, 6, 10 or 13 can not be regarded as weights of the juveniles.
Hence, the unique weights are 5, 6, 10 and 13

katie is planting a garden for her science fair project. she needs 2/3 of a cup of soil to go in 8 different pots.how many cups of total does she need in total
Answer:
5 and 1/3 cups of soil
Step-by-step explanation:
Hello there, in this problem we can solve for the amount of soil that Katie will need by multiplying the factor for one of them by the number of pots we have, 8. We get 16/3 cups of soil, or 5 and 1/3 cups of soil.
Hope this helps!
-HM
Answer:
Katie need 5.6 cups of soil.
Step-by-step explanation:
To solve this equation, we just need to multiply 8 by 2/3. Though to make this equation easier, I will turn 2/3 into a decimal by dividing the numerator (2) by the denominator (3.)
2 ÷ 3 = 0.7 when rounded to the nearest tenth.
Now, let's multiply 0.7 by 8.
8 x 0.8 = 5.6
Therefore, Katie need 5.6 cups of soil.
Hope this helps! :)

Priya has 50 identical parcels. Each parcel has a mass of 17 kg, correct to the nearest kilogram. Find the upper bound for the total mass of the 50 parcels.
Answer:
The upper bound for the total mass of the 50 parcels is 850 kilograms.
Step-by-step explanation:
From statement we infer that upper bound is represented by the 50 identical parcels completely full. Then, the upper bound is the product of number parcels and maximum capacity of each parcel:
[tex]m_{UP} = (50\,parcel)\cdot \left(17\,\frac{kg}{parcel} \right)[/tex]
[tex]m_{UP} = 850\,kg[/tex]
The upper bound for the total mass of the 50 parcels is 850 kilograms.

A real estate sales agent receives a salary of $250 per week plus a commission of 2% of sales.
a. Identify the Slope m _________
b. Identify the initial value b ________________
c. Write an equation that gives the weekly income y in terms of sales x ______________.
d. What is his weekly income if the sales were $600.00?
Answer:
a. The slope m is 0.02
b. The initial value b is 250
c. y = 0.02x + 250
d. His weekly income is $262 if the sales were $600.00
Step-by-step explanation:
the form of the linear equation is y = m x + b, where
m is the slope (rate of change)b is the y-intercept (constant amount)∵ A real estate sales agent receives a salary of $250 per week
→ This is a fixed amount every week
∴ b = 250
∵ They give a commission of 2% of sales
→ This value depends on the sales (rate of change)
∵ 2% = 2 ÷ 100 = 0.02
∴ m = 0.02
a. The slope m is 0.02
b. The initial value b is 250
∵ y represents the weekly income
∵ x represents the sales
∵ m = 0.02 and b = 250
∴ The equation is y = 0.02x + 250
c. y = 0.02x + 250
∵ The sales were $600.00
∴ x = 600
→ Substitute it in the equation to find y
∵ y = 0.02(600) + 250
∴ y = 12 + 250
∴ y = 262
d. His weekly income is $262 if the sales were $600.00
Water runs into a conical tank at the rate of [tex]9ft^{3}/min.[/tex] The tank stands point down and has a height of 10 ft and a base of 5 ft. How fast is the water level rising when the water is 6 ft deep?
Answer:
[tex]\frac{1}{\pi} \frac{\text{ft}}{\text{min}}[/tex] is the rate at which the water is rising when the water is 6 ft deep.
Step-by-step explanation:
See the attached diagram that I drew to represent this problem.
To solve related rates problems, let's use the recommended steps:
Draw a diagram.Label all quantities and their rates of change.Relate all quantities in the same equation.Differentiate (implicitly) with respect to time.Use the resulting equation to answer the question in context.Step 1:I already drew the diagram; see attached image.
Step 2:I labeled the quantities we are given in the problem. h = 10 ft, and r = 5 ft. We are also told that the change in volume is 9 ft³/min; dV/dt = 9 ft³/min.
We want to find dh/dt when h = 6.
[tex]\frac{dh}{dt}\ \vert \ _h_=_6 =\ ?[/tex] Step 3:We know that we are dealing with a cone in this problem, and we are given the volume of the cone. Therefore, we can use the formula for the volume of a cone in order to relate all of the quantities in the same equation.
[tex]V=\frac{1}{3} \pi r^2 h[/tex]Since we only want the two variables, V and h, we can solve for r in terms of h and substitute this value for r in the formula.
This is because when we perform implicit differentiation, we do not have the change in r (dr/dt) but we do have dh/dt, which is what we are trying to solve for.
We know that r = 5 ft, and h = 10 ft. Therefore, we can say that [tex]\frac{r}{h}=\frac{5}{10} \rightarrow \frac{r}{h} = \frac{1}{2}[/tex]. Multiply h to both sides to solve for the variable r: [tex]r=\frac{h}{2}[/tex].
Substitute this into the volume of a cone equation:
[tex]V=\frac{1}{3} \pi(\frac{h}{2})^2 h[/tex]Simplify this equation.
[tex]V=\frac{\pi}{3}\cdot \frac{h^2}{4} \cdot h[/tex] [tex]V=\frac{\pi}{12}h^3[/tex] Step 4:Perform implicit differentiation on the volume equation.
[tex]\frac{dV}{dt} =\frac{\pi}{12}3h^2 \cdot \frac{dh}{dt}[/tex] Step 5:Substitute known values and solve for dh/dt to find the change in height, or the rise in water level, when the water is 6 ft deep (h = 6).
We know that:
[tex]\frac{dV}{dt} =9[/tex] [tex]h=6[/tex]Plug these values into the implicitly differentiated volume equation.
[tex]9=\frac{\pi}{12}3(6)^2\cdot \frac{dh}{dt}[/tex] [tex]9=\frac{3\pi}{12}\cdot 36 \cdot \frac{dh}{dt}[/tex] [tex]9=9\pi\frac{dh}{dt}[/tex] [tex]\frac{dh}{dt} =\frac{9}{9\pi}= \frac{1}{\pi}[/tex]Answering the question in context:
Since dh/dt = 1/π when h = 6 ft, we can say that the water is rising at a rate of [tex]\frac{1}{\pi} \frac{\text{ft}}{\text{min}}[/tex] when the water is 6 ft high.
Hey there!
We can create some variables to denote some of the things we are working with.
v = volume
h = height
r = radius
We know that [ dv/dt = (π/3)r²h ]. We also know that [ r/h = 5/10 = 1/2 ] which resembles the parts of a triangle.
Solution:
v = π/3*h/2²
h = πh³/(4)(3)
~Differentiate both sides
dv/dt = (3πh³/4*3)(dh/dt)
~Simplify
dh/dt = (4dv/dt)/πh²
~Use chain rule
(4)(9)/π6²
1/π
Thus, the speed of the water level rising is [ 1/π ft/min ] when the water is 6ft deep.
Best of Luck!

Answer:

Step-by-step explanation:
Vector Calculus
A particle of mass m move along the path σ(t)={t^2,sin t, cos t} Calculate the force acting on the particle t=0.
It seems like σ(t) is the positive function of the particle. Compute its acceleration by differentiating this function twice.
σ(t) = {t ², sin(t ), cos(t )}
σ'(t) = {2t, cos(t ), -sin(t )}
σ''(t) = {2, -sin(t ), -cos(t )}
When t = 0, the acceleration on the particle is
σ'' (0) = {2, -sin(0), -cos(0)} = {2, 0, -1}
Then the force acting on the particle at time t = 0 is
F = {2m, 0, -m}
by Newton's second law.

A selective university advertises that 96% of its bachelor’s degree graduates have, on graduation day, a professional job offer or acceptance in a graduate degree program in their major area of study. In a sample of 227 recent graduates this was true of 209 of them. The probability of obtaining a sample proportion as low as or lower than this, if the university’s claim is true, is about:________
a. 0.015
b. 0.001
c. 0.131
d, 0.084
Answer:
The probability is [tex]P( p < 0.9207) = 0.0012556[/tex]
Step-by-step explanation:
From the question we are told
The population proportion is [tex]p = 0.96[/tex]
The sample size is [tex]n = 227[/tex]
The number of graduate who had job is k = 209
Generally given that the sample size is large enough (i.e n > 30) then the mean of this sampling distribution is
[tex]\mu_x = p = 0.96[/tex]
Generally the standard deviation of this sampling distribution is
[tex]\sigma = \sqrt{\frac{p (1 - p )}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.96 (1 - 0.96 )}{227} }[/tex]
=> [tex]\sigma = 0.0130[/tex]
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{209}{227}[/tex]
=> [tex]\^ p = 0.9207[/tex]
Generally probability of obtaining a sample proportion as low as or lower than this, if the university’s claim is true, is mathematically represented as
[tex]P( p < 0.9207) = P( \frac{\^ p - p }{\sigma } < \frac{0.9207 - 0.96}{0.0130 } )[/tex]
[tex]\frac{\^ p - p}{\sigma } = Z (The \ standardized \ value\ of \ \^ p )[/tex]
[tex]P( p < 0.9207) = P(Z< -3.022 )[/tex]
From the z table the area under the normal curve to the left corresponding to -3.022 is
[tex]P(Z< -3.022 ) = 0.0012556[/tex]
=> [tex]P( p < 0.9207) = 0.0012556[/tex]
Find the value of X.
Answer:
x = 9
Step-By-Step Explanation:
1. 3x + 5 + 6x + 4 = 90
2. 9x + 9 = 90
3. 9 + -9
4. 90 + -9
5. 9x = 81
6. x= 9 Substituting X:
3 X 9 + 5 = 27 + 5 = 32
6 X 9 + 4 = 54 + 4 = 58 58 + 32 = 90, so X = 9
Answer:
Step-by-step explanation:
The reason I say the answer above is wrong is because their answer equals up to a angle of 100 degrees however your angle is equaling up to 90 degrees. First off we know this angle is going to be 90 degrees right so we put it into the eqution:
=90
but we don't know what x is in order to solve the degrees that add up to 90, so since these equations add up to 90 we put them into the equation:
(3x + 5)+ (6x + 4) = 90
we then add all the numbers that have the same variables or are simply numbers in the equation
3x + 6x and 5 + 4 to get 9x + 9 = 90
we then subtract 9 from both sides (because what you do to one side you do to the other) to get 81
the equation now looks like this: 9x = 81 so now we divide 9 from both sides to get x = 9
Now how do we know if x is really 9 well we plug it into the equations (3x + 5) and (6x + 4) making them look like this (3(9) + 5) and (6(9) + 4)
and you get (3(9) + 5)= 32
(6(9) + 4)= 58
and when you add them together you get 90
32 + 58 = 90
Sorry it took so long to answer back. I hope this helps you
