The probability that a randomly selected tire will have a life of at least 47,500 miles is 6.68%, which corresponds to answer choice c: .0668.

Probability is a mathematical concept that measures the likelihood or chance of an event occurring.It is a number between 0 and 1, with 0 designating an impossibility and 1 indicating a certainty. The probability of an event is calculated as the number of favorable outcomes divided by the number of possible outcomes.

The probability that a randomly selected tire will have a life of at least 47,500 miles can be found using a normal distribution and the z-score formula.

The z-score is calculated as follows:

z = (47,500 - 40,000) / 5,000 = 3.5

Using a standard normal table or calculator, we can find the cumulative probability associated with a z-score of 3.5. The probability that a randomly selected tire will have a life of at least 47,500 miles is:

P(X >= 47,500) = 1 - P(X < 47,500) = 1 - .9993 = .0007

Therefore, the answer is: c. .0668

To determine if there has been a change in the distribution of motivations for using a credit card among college students, a survey of 425 students was conducted.

The alternate hypothesis states that the distribution of motivations differs from the old survey. The critical value and rejection region need to be determined to test this hypothesis.

To test if there has been a change in the distribution of motivations, the null hypothesis assumes that the distribution remains the same as in the old survey, while the alternate hypothesis suggests a difference. In this case, the alternate hypothesis is that the distribution of motivations differs from the old survey.

To determine the critical value and rejection region, the significance level (α) needs to be specified. In this case, α is given as -0.005. However, it seems there may be some confusion in the provided information, as a negative significance level is not possible. The significance level should typically be a positive value between 0 and 1.

Without a valid significance level, it is not possible to determine the critical value and rejection region for hypothesis testing. The critical value is typically obtained from a statistical table or calculated based on the significance level and the degrees of freedom.

In conclusion, without a valid significance level, it is not possible to determine the critical value and rejection region to test the hypothesis regarding the change in the distribution of motivations for credit card usage among college students.

-2 is the minimum value of the given set.

Assume that x is the minimum value.

The difference between the largest value and the least value is therefore what we use to determine the range:

Range = Maximum value - Minimum value

6 = 4 - x

Solving for x, we can subtract 4 from both sides:

6 - 4 = 4 - x - 4

2 = -x

Finally, we can multiply both sides by -1 to get x by itself:

x = -2

The sum is 40,000.

The difference between compound interest and simple interest is 324 on a certain sum at 9% for 2 years.

So,

Compound interest - Simple interest = 324

C.I - SI = 324

The formula for compound interest is given as:

C.I = P( 1 + r/100 )ⁿ - P

Where P is the principal amount, r is the rate and n is the time in years.

Therefore,

C.I = P( 1 + 9/100)² - P

C.I = P( 1 + 0.09)² - P

C.I = P(1.09)² - P

C.I = 1.1881P - P

C.I = 0.1881P

Now, the formula for simple interest is given as:

S.I = ( P × R × T / 100 )

Where P is the principal amount, R is the rate and T is time in years.

Therefore,

S.I = ( P × 9 × 2 / 100 )

S.I = 18P / 100

S.I = 0.18P

Now,

C.I - S.I = 324

0.1881P - 0.18P 324

0.0081P = 324

P = 324 / 0.0081

P = 324 × 10000 / 81

P = 4 × 10000

P = 40000

Hence, the principal amount is 40,000.

By separating the variables, the given differential equation will be cosy = -1/2 sin2x + C.

Differential equation definition

Differential equations are those that have derivatives of one variable with regard to another variable quantity.

Any arrangement of derivatives is possible, and certain words may include a derivatives-and-variable product or derivatives by themselves. They might also have several different variables.

The differential equation shown is

csc(y) dx = sec2(x) dy

The fact that

csc(y) = 1/ siny

1/cosx = sec(x)

We can also write it;

dy/cos2x = dx/siny

Cross multiplication with variable separation.

Cos2x dx = siny dy

In distinction;

cosy = -1/2 sin2x + C

Answer:

  (x +6)(3x +4)

Step-by-step explanation:

The usual approach to this is to look for factors of the product 3·24 that have a sum of 22.

  72 = 1·72 = 2·36 = 3·24 = 4·18 = 6·12 = 8·9

Sums of these factor pairs are 73, 38, 27, 22, 18, 17.

Now, you can rewrite the expression splitting the middle term into two parts:

  3x² +4x +18x +24

  x(3x +4) +6(3x +4) . . . . . . factor by grouping

  (x +6)(3x +4) . . . . . . . . . . your factored form

_____

Additional comment

I find this method easiest to explain and to do without error. There are various "X" methods in which you write the product at the top (3·24) and the sum at the bottom (22), then fill in the sides with the factors having that product and sum (4, 18). When the leading coefficient is not 1, there are methods added to this that get you to the correct factors.

One such method is to use the leading coefficient inside parentheses: (3x+4)(3x+18) Then divide that product by the leading coefficient:

  (3x +4)(3x +18)/3 = (3x +4)(x +6).

In some cases, each of the binomials needs to be divided by part of the leading coefficient; not the whole thing, as here.

\(\\ \sf\Rrightarrow 3x^2+22x+24\)

\(\\ \sf\Rrightarrow 3x^2+18x+4x+24\)

\(\\ \sf\Rrightarrow 3x(x+6)+4(x+6)\)

\(\\ \sf\Rrightarrow (3x+4)(x+6)\)

Therefore, the projectile goes approximately 6.9 × 10^6 meters or 6,900 kilometers high.

Let's first convert the initial speed from km/hr to m/s to be consistent with the unit of acceleration due to gravity.

1.30×10^4 km/hr = (1.30×10^4 × 1000 m/km) / (3600 s/hr) = 3611.11 m/s

We can use the kinematic equation: Δy = v0t + 1/2at^2 to determine the maximum height reached by the projectile. At the highest point, the velocity is zero, so we can use the fact that v = v0 + at = 0 to find the time it takes to reach the maximum height.

v0 = 3611.11 m/s (initial velocity)

a = -9.81 m/s^2 (acceleration due to gravity)

t = -v0/a = -3611.11/(-9.81) = 367.97 s (time to reach maximum height)

Now we can use the time to find the maximum height reached:

Δy = v0t + 1/2at^2 = 3611.11 × 367.97 + 1/2 × (-9.81) × (367.97)^2 ≈ 6.9 × 10^6 meters

The value of R(x) term is 36.

We are given that;

The equation x³ + 2x² - 72x - 28

Now,

We divide the first term, 8x, by the first term of d(x), which is x. This gives us 8, which is the third term of Q(x). We write 8 above the division bar and multiply it by d(x), which gives us 8x - 64. We subtract this from the new dividend, which gives us 36.

Since we cannot divide 36 by x-8 any further, we stop here and write 36 as the remainder R(x).

   x² + 10x + 8

T test is used to compute the confidence interval, when the mean and standard deviation is given.

What is Standard Deviation?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be very close to the set mean. The lower case Greek letter (sigma), again for population standard deviation, or even the Latin letter s, again for sample standard deviation, are most frequently used in mathematical texts and equations to represent standard deviation. Standard deviation may be abbreviated as SD. A random variable, specimen, statistical population, data set, as well as probability distribution's standard deviation is equal to the square root of its variance. When the number in a sample, sample mean and sample standard deviation is given, the test statistic that should be used when computing a confidence interval is t test

Answer: To determine the cost of Rob's lunch, we need to calculate the total amount he paid, including the cost of the meal and the tip.

Given that Carla's lunch cost $15 and the tip amount was $6, we can find the total amount Rob paid by dividing the tip amount by the tip percentage:

Total amount paid = Tip amount / (Tip percentage / 100)

In this case, the tip amount is $6 and the tip percentage is 20%.

Total amount paid = $6 / (20 / 100) = $6 / 0.20 = $30

So, Rob's total payment, including the cost of his lunch and the tip, was $30.

Since we know that Carla's lunch cost $15, we can subtract this amount from the total payment to find the cost of Rob's lunch:

Cost of Rob's lunch = Total amount paid - Carla's lunch cost = $30 - $15 = $15

Therefore, the cost of Rob's lunch was $15.

In the given case, 36 square feet will need to be painted.

To calculate the surface area that needs to be painted, we need to determine the total surface area of both the square prism and the square pyramid, and then subtract the area of the base of the pyramid, as it will not be painted.

The surface area of a square prism with base dimensions of 8 ft by 8 ft and height of 9 ft is:

Top and bottom: 8 ft x 8 ft = 64 sq ft each (2 x 64 = 128 sq ft)

Four sides: 8 ft x 9 ft = 72 sq ft each (4 x 72 = 288 sq ft)

Total surface area of the prism: 2(64 sq ft) + 4(72 sq ft) = 256 sq ft

The surface area of a square pyramid with slant height of 5 ft can be calculated by finding the area of each face and adding them together. Each face is a triangle, and the area of a triangle can be calculated using the formula: (base x height) / 2.

Base: 8 ft x 8 ft = 64 sq ft

Each triangular face: (1/2)(8 ft)(5 ft) = 20 sq ft

Total surface area of the pyramid: 4(20 sq ft) + 64 sq ft = 144 sq ft

Therefore, the total surface area that needs to be painted is:

256 sq ft + 144 sq ft - 64 sq ft = 336 sq ft

So, 336 square feet will need to be painted.
