The chance to not hit the target is 65 percentage. This means that there is a 65% chance that the hunter will miss the target.

The percentage of a hunter to hit a target is .35, which means that there is a 35% chance that the hunter will hit the target. This leaves a 65% chance that the hunter will miss the target. This means that there is a 65% chance that the hunter will not hit the target. This percentage is determined by the accuracy of the hunter, the size of the target, and any other external factors that may affect the accuracy of the hunter's shot. Accuracy is determined by the hunter's skill, experience, and the quality of the equipment used. The size of the target is also a factor, as it can be harder to hit a smaller target. Additionally, any environmental factors present, such as wind or rain, can cause the shot to go astray. All of these factors combine to determine the chance that the hunter will have to make or miss the target.

The mixed third partial derivative of the function f(x, y, z) = x² + y² + z² with respect to x, y, and z is zero.

To find the mixed third partial derivative of the function f(x, y, z) = x² + y² + z² with respect to x, y, and z, we need to take the partial derivative with respect to x, then y, and finally z. Let's compute each step:

Taking the partial derivative with respect to x:

∂f/∂x = 2x

Taking the partial derivative of the result with respect to y:

∂(∂f/∂x)/∂y = ∂(2x)/∂y = 0

Taking the partial derivative of the previous result with respect to z:

∂(∂(∂f/∂x)/∂y)/∂z = ∂(0)/∂z = 0

Therefore, the mixed third partial derivative ∂³f/(∂x∂y∂z) is equal to 0.

This means that the function f does not have any dependence or variation with respect to the simultaneous changes in x, y, and z.

The derivative of f(x) = sech^(-1)(x^2) is f'(x) = 2x/sqrt(1 - x^4).

a) To find f'(x) for f(x) = x*sin(x), we can use the product rule and the derivative of the sine function.

Using the product rule, we have:

f'(x) = (xsin(x))' = xsin'(x) + sin(x)*x'

The derivative of sin(x) is cos(x), and the derivative of x with respect to x is 1. Therefore:

f'(x) = x*cos(x) + sin(x)

So, the derivative of f(x) = xsin(x) is f'(x) = xcos(x) + sin(x).

(b) To find f'(x) for f(x) = sech^(-1)(x^2), we can use the chain rule and the derivative of the inverse hyperbolic secant function.

Let u = x^2. Then, f(x) can be rewritten as f(u) = sech^(-1)(u).

Using the chain rule, we have:

f'(x) = f'(u) * u'

The derivative of sech^(-1)(u) can be found using the derivative of the inverse hyperbolic secant function:

(sech^(-1)(u))' = 1/sqrt(1 - u^2)

Since u = x^2, we have:

f'(x) = 1/sqrt(1 - (x^2)^2) * (x^2)'

Simplifying:

f'(x) = 1/sqrt(1 - x^4) * 2x

So, the derivative of f(x) = sech^(-1)(x^2) is f'(x) = 2x/sqrt(1 - x^4).

Answer:

Side a = 35ft

Side b = 35ft

Side c = 20ft

Step-by-step explanation:

The formula for the perimeter of a triangle = Side a + Side b + Side c

In an isosceles triangle, 2 sides are equal to each other.

So, Side a = Side b

In the question, we are told that:

The two equal sides are each 5 ft less than twice the length of the third side.

Hence,

a = 2c - 5

b = 2c - 5

P = 90ft

P = a + b + c

90 = 2c - 5 + 2c - 5 + c

Collect like terms

90 = 5c - 10

90 + 10 = 5c

100 = 5c

c = 100/5

c = 20

The length of the third side = 20ft

a = 2c - 5

= 2 × 20 - 5

= 40 - 5

= 35 ft

b =2c - 5

= 2 × 20 - 5

= 40 - 5

= 35 ft

Therefore,

Side a = 35ft

Side b = 35ft

Side c = 20ft

The amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly is Rs 1893.09.

The amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly can be calculated as follows:

Given, Principal = Rs 1200Time = 1.5 yearsInterest rate = 40% per annum, compounded quarterly

Let r be the quarterly rate of interest. Then we can convert the annual interest rate to quarterly interest rate using the following formula: \text{Annual interest rate} = (1 + \text{Quarterly rate})^4 - 1$$

Substituting the values, we get:0.40 = (1 + r)^4 - 1 Solving for r, we get:r = 0.095 or 9.5% per quarter

Now, we can use the formula for the amount of money after time t, compounded quarterly: $A = P \left( 1 + \frac{r}{4} \right)^{4t}

Substituting the values, we get:A = Rs 1200 x $\left(1 + \frac{0.095}{4} \right)^{4 \times 1.5}= Rs 1893.09

Therefore, the amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly is Rs 1893.09.

the number of distinct seating arrangements when two seatings are considered the same when everyone has the same two  without neighbors regard to whether they are right or left neighbors is:5!6⋅2=10.6⋅25! = 10

There are $(6-1)! = 5! = 120$ ways to seat six people around a circular table if the seatings are considered distinct. However, we must divide this number by $6$ to account for the fact that rotations of the same seating arrangement are considered the same. We also must divide by $2$ to account for the fact that reflections (i.e., reversing the order of people) of the same seating arrangement are also considered the same.

If the interquartile range is much longer than either of the whiskers and there are no outliers, it suggests that the data is evenly distributed within the middle 50% of the dataset, but there is a significant spread of values beyond that range. This indicates a relatively large variation or dispersion in the dataset.

The interquartile range (IQR) is a measure of variability that represents the range between the first quartile (Q1) and the third quartile (Q3) of the dataset. When the IQR is much longer than either of the whiskers (which represent the minimum and maximum values within 1.5 times the IQR), it implies that the middle 50% of the data is relatively tightly clustered, while there are values that extend far beyond that range.

The absence of outliers suggests that there are no extreme values or observations that deviate significantly from the rest of the data. This indicates a more consistent distribution without any unusual or aberrant data points. However, the extended interquartile range implies a significant spread or dispersion of values beyond the central portion of the dataset.

Answer:

$1.75

Step-by-step explanation:

First, find the cost of just the socks. Subtract the total cost by the cost of the shirt.

total cost - cost of shirt

We know that the socks and shirt cost $22.95. We also know a shirt costs $8.95, so we can subtract $8.95 from $22.95.

$22.95 - $8.95

$14

It cost $14 for the socks.

Now, find the cost of each pair of socks. Divide the sock cost by the pairs.

sock cost/pairs

We know that each pair costs the same amount, and 8 pairs were purchased. Therefore, we can divide $14 by 8.

a. ln(7x) can be expanded as ln(7) + ln(x). b. ln(x + 3) remains as it is, since it cannot be simplified further. c. ln(x^8) can be expanded as 8ln(x). d. 15,000ln(xy^4) can be expanded as ln(x) + 4ln(y) + ln(15,000).

a. To expand the logarithmic expression ln(7x), we can use the property of the natural logarithm that states ln(ab) = ln(a) + ln(b).

Therefore, ln(7x) can be expanded as ln(7) + ln(x).

b. Similarly, the logarithmic expression ln(x + 3) can be expanded using the property ln(ab) = ln(a) + ln(b).

Hence, ln(x + 3) remains as it is since we cannot simplify it further.

c. Expanding the logarithmic expression ln(x^8) can be done using the property ln(a^b) = b * ln(a).

Thus, ln(x^8) becomes 8 * ln(x).

d. Expanding the logarithmic expression 15,000ln(xy^4) can be done by applying the property ln(ab) = ln(a) + ln(b).

Therefore, 15,000ln(xy^4) can be expanded as 15,000[ln(x) + ln(y^4)].

(a) The probability that there will be exactly 3 eruptions in the next 200 years is 0.1404

(b) The probability the next eruption occurs between 25 and 50 years is 0.2488

Let X be the random variable denoting the volcanic eruptions as follows

Poisson distribution with parameters  λ.

the average of the eruption is  λ=2.5 per year.

Also for 200 eruptions the average of the eruptions is  λ=2.5 per year.

Also, for 200 eruptions, the average of the eruptions is  λ=5 per year.

The probability is:

P(X=3) = e⁻³(5)³/3!

= 0.0067×125/3×2×1

= 0.8422/6

= 0.1404

(b) Let X be the random variable denoting the volcanic eruptions as follows

Poisson distribution with parameters  λ and also let 2.5 eruptions in 100 years is same as waiting time of:

100/2.5

= 40 years per eruption

therefore, X ~ Exp(β=40)

the probability density function of X is:

f(x) = { 1/40 e⁻¹/⁴⁰ , x>0

          0 ,  otherwise}

And cumulative distribution function is:

P(X≤x) = 1 - e, x>0

the probability is:

P(25<X<50) = P(X<50)-P(X<25)

P(25<X<50) = e²⁵/⁴⁰ - e⁵⁰/⁴⁰

= e⁻°·°²⁵ - e⁻¹·²⁵
