The process capability index for the process is 0.1754.

The first sided specification limit will be:

= (Upper specification limit - mean)/(3 × standard deviation)

= (23.1 - 22.9)/(3 × 0.19)

= 0.2/0.57

= 0.3508

The second sided specification limit will be:

= (22.9 - 22.8)/(3 × 0.19)

The value of variable x that makes -4x-(-10 - 8x) = -(12x-14) true is 1/4. thus, option c is correct.

An equation's unknown numerical value is represented by a symbol (typically a letter) called a variable in algebra. X and Y, which are real-number unknowns, as well as z, which are complex-number unknowns, as well as t, r, and s are frequently used variables (arc length).

Given

-4x-(-10 - 8x) = -(12x-14)

-4x + 10 + 8x = -12x + 14

4x + 10 = 14 - 12x

4x + 12x = 14 - 10

16x = 4

x = 4/16

x = 1/4

Thus, Option C is correct, x = 1/4

Answer:

Scalene, isosceles and equilateral triangle are the types of triangles

Step-by-step explanation:

They  differ from each other based on their side-length. If all the three sides are different in length, then its scalene triangle. If any two sides are equal in length, then it is an isosceles triangle.

This means that we can be 95% confident that the true population means difference lies between 1.7075 and 10.2925.

Confidence interval = Mean difference ± (t-value × standard error)

Substituting the given values into the formula, we get:

Confidence interval = 6 ± (2.045 × 2.1)

Confidence interval = 6 ± 4.2925

A confidence interval is a statistical concept used to estimate the range of values in which a population parameter is likely to fall. It is calculated using sample data and is used to provide an estimate of the true population parameter.

The confidence interval is a range of values that is constructed around a point estimate, such as the sample mean or proportion. This range is based on the level of confidence chosen by the researcher, typically 90%, 95%, or 99%. For example, a 95% confidence interval means that if we were to repeat the sampling process many times, we would expect the true population parameter to fall within the range of values calculated for 95% of those samples.

The mean number of people living in a household was 6.208, indicating that the average household size in South Africa is approximately six people.

The Census At School survey project collected data from an SRS of 48 South African students to estimate the number of people living in South African households.

The standard deviation of 2.576 indicates that there is considerable variation in household size, with some households having fewer than four people and others having more than eight people.

The sample size of 48 is relatively small compared to the total population of South Africa, which is over 58 million people. Therefore, the estimates based on this sample may not accurately reflect the entire population. However, the use of random sampling techniques, such as SRS, helps to minimize bias and increase the representativeness of the sample.

Overall, the data collected from the Census At School survey project provides a valuable insight into the average household size in South Africa. This information can be used by policymakers and researchers to inform decisions regarding housing, healthcare, and other public services.

The Complete question is:

How many people live in South African households? To find out, we collected data from an SRS of 48 out of the over 700,000 South African students who took part in the CensusAtSchool survey project. The mean number of people living in a household was 6.208; the standard deviation was 2.576.

The integral of x(4x + 7)^8dx is (1/16)((4x + 7)^10/10 - 7(4x + 7)^9/9) + C.

To evaluate the indefinite integral of x(4x + 7)^8dx, we will use the substitution method.

First, let's make a substitution:

u = 4x + 7

du = 4dx

dx = (1/4)du

Now we can substitute u and du into the integral:

∫x(4x + 7)^8dx = ∫(1/4)(u - 7)(u)^8(1/4)du

= (1/16)∫(u^9 - 7u^8)du

Next, we will use the power rule to integrate:

= (1/16)(u^10/10 - 7u^9/9) + C

Finally, we will substitute back in for u:

= (1/16)((4x + 7)^10/10 - 7(4x + 7)^9/9) + C

So the integral of x(4x + 7)^8dx is (1/16)((4x + 7)^10/10 - 7(4x + 7)^9/9) + C.

Answer:

x=25°

Step-by-step explanation:

If angle A and angle B are complementary angles, it means that the sum of their measures is equal to 90 degrees.

Let's denote the measure of angle A as x. Since angle B is given as 65 degrees, we can write the following equation:

x + 65 = 90

To solve for x, we can subtract 65 from both sides of the equation:

x = 90 - 65

x = 25

Therefore, the value of x is 25.

Answer:

x=25

Step-by-step explanation:

Complementary angles:

Complementary angles are 2 angles that when added together, equals 90 degrees, or a right angle.

We already know that they are complementary, but we have to find the measure of 1 angle, given the other angle measure.

We can write an equation like this:
90=65+x

subtract 65 from both sides

25=x

So, x=25.

What is the given expression?`x2 x − 2x3 − x2 2x − 2`To write it in the simplest form, we will first group the like terms:x2 x − x2 2x − 2x3 − 2On combining `x2 x` and `-x2`, we get:x2 x − x2=0This simplifies the expression to:`−2x3−2`Taking `-2` common from the above expression, we get:-2(x3+1)

Therefore, the given expression in its simplest form is:-2(x3+1) or -2x³-2Now, let's move onto the options given. a. `x−1x22`This option can be written as `x(1-x2)/2(x-1)`.

The shipping and handling price is $174.96

The price of the gold ring = $699.84

Shipping and handling price is 25% of the price of the gold ring.

x% means x/100. So 25 % = 25/100 in ratio.

x% of y can be found by (x/100) x y = xy/100

So, (25/100) x 699.84 = (1/4) x 699.84 = $ 174.96.

Let us now consider a uniformly tapering circular bar having length,

L = 10 inches

and having diameter,

d₁ = 2 inches

at one end and

d₂ = 4 inches

at the other end, therefore we know that d₂ > d₁

let us consider a very short section xx of length kx and diameter dx, situated at a distance x from end A

now diameter, dx = d₁ + (d₂ - d₁)x

= d₁ + kx

The f′(a) when a = −6 is -7. This means that the slope of the tangent line of the graph of f(x) at x = -6 is -7.

To compute f′(a) algebraically for the given value of a, we use the following differentiation rule which is known as the Power Rule.

This states that:If f(x) = xn, where n is any real number, then f′(x) = nxⁿ⁻¹This is valid for any value of x.

Therefore, we can differentiate f(x) = −7x + 5 with respect to x using the power rule as follows:

f(x) = −7x + 5

⇒ f′(x) = d/dx (−7x + 5)

⇒ f′(x) = d/dx (−7x) + d/dx(5)

⇒ f′(x) = −7(d/dx(x)) + 0

⇒ f′(x) = −7⋅1 = −7

Hence, the derivative of f(x) with respect to x is -7.Now, we evaluate f′(a) when a = −6 as follows:f′(x) = −7 evaluated at x = −6⇒ f′(−6) = −7

Therefore, f′(a) when a = −6 is -7. This means that the slope of the tangent line of the graph of f(x) at x = -6 is -7.

Explanation:

The distribution of the number of cars on the highway during two hours follows a binomial distribution with parameters n=2 and p=0.86, and the expected number of cars that will pass the highway before the first truck is approximately 1.16 cars.

(a) The distribution of the number of cars on the highway during two hours follows a Poisson distribution with a rate of 300 cars per hour. Since each vehicle is a car with a probability of 86%, we can use the binomial distribution to determine the probability of a specific number of cars in the two hours. The probability mass function of the number of cars, denoted by X, can be calculated as \(P(X = k) = (2Ck) * (0.86)^k * (0.14)^2^-^k\), where k ranges from 0 to 2. This gives us the probability distribution of the number of cars in the two hours.

(b) To determine the expected number of cars that will pass the highway before the first truck, we can utilize the geometric distribution. The probability of a car passing the highway before the first truck is 86%. Therefore, the expected number of cars, denoted by Y, can be calculated as \(E(Y) = 1 / 0.86 = 1.16\) cars. This means that on average, approximately 1.16 cars will pass the highway before the first truck.
