A pound has 60 German Shepherds and 40 Great Danes of both sexes. If they breed with each other randomly, what is the probability that the puppies are: (i) pure breed German Shepherds, (ii) pure breed Great Danes, (iii) German Shepherd-Great Danes
Answer:
(i) pure breed German Shepherds,= 0.6
(ii) pure breed Great Danes,= 0.4
(iii) German Shepherd-Great Danes= 0.24
Step-by-step explanation:
The probability of success for the German shepherd is 60/100 0r 6/10 0r 0.6
The probability of failure for the German shepherd is 40/100 0r 4/10 0r 0.4
The probability of success for the Great Danes is 40/100 0r 4/10 0r 0.4
The probability of failure for the Great Danes is 60/100 0r 6/10 0r 0.6
The probability that it is a pure German shepherd is 60/100 0r 6/10 0r 0.6
The probability that it is a pure the Great Danes is 40/100 0r 4/10 0r 0.4
The probability that the puppies are: German Shepherd-Great Danes is given by since the events are independent

Find the area of the figure shown below and choose the appropriate result.
4 cm
2 cm
5 cm
6 cm
A 34 cm2
B 44 cm
54 cm
D 46 cm
Answer:
the answer is D 46 cm
Step-by-step explanation:
first you need to find the missing side measurements cutting in two separate figures. if one side is 2 you know the other side is also 2 same with the 4 if the top is 4 the bottom is 4 too so now you have the measurements for the first figure now you finder the area applying the formula
A=bxh
A= 4*2=8
second figure you know that one part of the rectangle top is 5 and if you add the 4 of the first figure give you the measurement of the top
5+4=9 so if the top is 9 the bottom is also 9
finally to find the other side you know the side is 6 and since you know one part of the first figure is 2 you need to subtract 6-2=4
A=bxh
A=9*4=28
once you have both you can add it 28+8=46
The data in which table represents a linear function that has a slope of zero? X -5 -4 -3 -2 -1 у 5 5 5 5 5 w х 1 2 3 4 5 y -5 -4 -3 -2 -1 X -5 -4 -3 -2 y 5 4 3 2
Answer: the answer is choice b
Step-by-step explanation:
The data in the first table represents a linear function that has a slope of zero
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Slope (m) = change in y / change in x
From the first table, using the point (-5, 5) and (-1, 5), hence:
Slope = (5 - 5)/(-1 - (-5)) = 0

Leanna has a rectangular piece of fabric. The fabric is 24 inches wide and 40 inches long. Leanna folds the piece of fabric along its diagonal to form a triangular scarf.
What is the area, in square inches, of the triangular scarf?
Answer:
480 square inches
Step-by-step explanation:
width = base = 24 inches
length = height = 40 inches
area of the triangular scarf = 1/2 * base * height
= 1/2 * 24 * 40
= 480 square inches
Once a month, Eddie cashes his paycheck at a check cashing service that charges a 1% fee. If Eddie gets paid $500 per month, which of the following will be true?
Answer:
He should be paying $5 monthly.
Step-by-step explanation:
500*0.01=5, I think this was a question from flocabulary, next time, try to also add the answer choices.
The true statement is that the amount of money which Eddie would be charged for each monthly withdrawal is equal to $5.
What is a paycheck?A paycheck refers to a financial document issued to an employee by an employer, as payment for the work done over a specific period of time.
How to calculate the service charge.Since the interest on Eddie's monthly withdrawal is 1% (0.01), it simply means that the service charge would be calculated by multiplying his wages by the interest rate.
Service charge = 500 × 0.01
Service charge = $5.

Let X1, X1, ..., X64 be a i.i.d. random sample of size 64 from a distribution with probability density function: f(x) = 6x(1 − x), 0 < x < 1 Approximate P(0.45 < X <¯ 0.5). Hint: find µ and σ 2
Answer:
The approximate value of [tex]P(0.45<\bar X<0.50)[/tex] is 0.3686.
Step-by-step explanation:
The pdf of X is:
[tex]f(x) = 6x(1-x), 0 < x < 1[/tex]
Compute the mean as follows:
[tex]\mu=\int\limits^{1}_{0} {x\times 6x(1-x)} \, dx \\\\=\int\limits^{1}_{0} {6x^{2}-6x^{3}} \, dx\\\\=[\frac{6x^{3}}{3}]-[\frac{6x^{4}}{4}]|^{1}_{0}\\\\=2-\frac{3}{2}\\\\=0.50[/tex]
Compute the variance as follows:
[tex]\sigma^{2}=E(X^{2})-(\mu)^{2}[/tex]
[tex]E(X^{2})=\int\limits^{1}_{0} {x^{2}\times 6x(1-x)} \, dx \\\\=\int\limits^{1}_{0} {6x^{3}-6x^{4}} \, dx\\\\=[\frac{6x^{4}}{4}]-[\frac{6x^{5}}{5}]|^{1}_{0}\\\\=\frac{3}{2}-\frac{6}{5}\\\\=0.30[/tex]
[tex]\sigma^{2}=E(X^{2})-(\mu)^{2}\\\\\sigma=\sqrt{E(X^{2})-(\mu)^{2}}\\\\=\sqrt{0.30-(0.50)^{2}}\\\\=0.2236[/tex]
According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.
Then, the mean of the sample means is given by,
[tex]\mu_{\bar x}=\mu[/tex]
And the standard deviation of the sample means is given by,
[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]
The sample selected is of size n = 64 > 30. Thus a central limit theorem can be applied to approximate the sampling distribution of sample mean.
Compute the value of [tex]P(0.45<\bar X<0.50)[/tex] as follows:
[tex]P(0.45<\bar X<0.50)=P(\frac{0.45-0.50}{0.2236/\sqrt{64}}<\frac{\bar X-\mu_{\bar x}}{\sigma_{\bar x}}<\frac{0.50-0.50}{0.2236/\sqrt{64}})[/tex]
[tex]=P(-1.12<Z<0)\\\\=P(Z<0)-P(Z<-1.12)\\\\=0.50-0.13136\\\\=0.36864\\\\\approx 0.3686[/tex]
Thus, the approximate value of [tex]P(0.45<\bar X<0.50)[/tex] is 0.3686.

Step-by-step explanation:
Water is being drained from a container which has the shape of an inverted right circular cone. The container has a radius of 5.00 inches at the top and a height of 6.00 inches. At the instant when the water in the container is 4.00 inches deep, the surface level is falling at a rate of 0.7 in./sec. Find the rate at which water is being drained from the container.
The rate at which water is being drained from the container is;
dV/dt = 24.4 in³/s
I've attached an image showing this inverted cone with the corresponding letters to represent the height and radius.
We are given;
Radius of Cone; R = 5 inches
Height of cone; H = 6 inches
h = 4 inches
Height rate of change; dh/dt = 0.7 in/s
Looking at the image attached, we can use similar triangle property to derive the relationship;
r/R = h/H
Where r is the radius at the instant where dh/dt = 0.7 in/s
Thus;
r/5 = 4/6
r = (5 × 4)/6
r = 3.33 inches
Now, from r/R = h/H
We can write with initial values of cone and differentiate;
r/5 = h/6
6r = 5h
6(dr/dt) = 5(dh/dt)
Since dh/dt = 0.7 in/s
Thus;
dr/dt = (5/6) × 0.7
dr/dt = 0.5833
Volume of cone is given by;
V = ⅓πr²h
We can find the rate at which the rate at which water is being drained from the container using partial differentiation on the volume equation.
Thus;
dV/dt = ⅓π((2rh × dr/dt) + (r² × dh/dt))
Plugging in the relevant values, we have;
dV/dt = ⅓π((2 × 3.33 × 4 × 0.5833) + (3.33² × 0.7))
dV/dt = 24.4 in³/s

The grades of an exam whose mean is 82 and whose standard deviation is 14 are normally distributed. Anyone who scores below 55 will be retested. What percentage does this represent
Answer:
This represents 2.6803%
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x - mean)/SD
here our x is 55
mean = 82
SD = 14
z-score = (55-82)/14
z-score = -1.93
So the probability that a test taker will be retested will be;
P( x < -1.93)
We use the standard normal distribution table for this
P( x < -1.93) = 0.026803
If we convert this to percentage, we have 2.6803%
