Quadrilateral STUV is similar to quadrilateral WXYZ. Find the measure of side XY.
Figures are not drawn to scale.

Answer:

1/2

Step-by-step explanation:

Find the following limit:

lim_(x->∞) (x + 1)/(1 x + sqrt(x)^2 + 1)

(x + 1)/(1 x + sqrt(x)^2 + 1) = (x + 1)/(2 x + 1):

lim_(x->∞) (x + 1)/(2 x + 1)

The leading term in the denominator of (x + 1)/(2 x + 1) is x. Divide the numerator and denominator by this:

lim_(x->∞) (1 + 1/x)/(2 + 1/x)

The expressions 1/x and 1/x both tend to zero as x approaches ∞:

.13 can be expressed in the form of percentage as 13%.

In order to convert numbers in decimal into percentage we only need to multiply the given number with 100 and after multiplying the number with hundred it can be written in percentage form. Like in the question given number is 0.13 and we need to express this in form of percentage. So in order to express this number in percentage we just multiply it with 100 which will be equal to 13% i.e

0.13 x 100 = 13%

By multiplying a decimal value by 100 and adding the percentage (%) sign, you can turn a decimal value into a percentage. A decimal multiplied moves the decimal point two places to the right.

The pk[tex]_b[/tex] of given acid conjugate base is 9.74 if k[tex]_a[/tex] of the same acid is equal to 5.57×10⁻⁵

The Bronsted-Lowry corrosive base hypothesis incorporates the ideas of form acids and form bases. At the point when a corrosive separates into its particles in water, it loses a hydrogen particle. The species that is shaped is the corrosive's form base.

A more broad definition is that a form base is the base part, X-, of a couple of mixtures that change into one another by acquiring or losing a proton. The form base can acquire or retain a proton in a synthetic response. The form corrosive gives the proton or hydrogen in the response.

In a corrosive base response, the substance response is:

Corrosive + Base ⇌ Form Base + Form Corrosive

We know very well that from equilibrium state theories that  pk[tex]_b[/tex] +pk[tex]_a[/tex] =14

where  pk[tex]_a[/tex] = - log( k[tex]_a[/tex] )

So, we have k[tex]_a[/tex] =5.57×10⁻⁵

Taking log of  k[tex]_a[/tex] ,we get

=>pk[tex]_a[/tex]= -log(5.57×10⁻⁵)

Using properties of logarithm, log(a × b)=log(a)+log(b)

=>pk[tex]_a[/tex]= -log(5.57) -log(10⁻⁵)

=>pk[tex]_a[/tex]= -0.745 +5

=>pk[tex]_a[/tex]=4.25

Therefore, from above written formula, we get

=>4.25+pk[tex]_b[/tex]=14

=>pk[tex]_b[/tex]=14-4.25

=>pk[tex]_b[/tex]=9.74

Hence, pk[tex]_b[/tex] value is 9.74

Answer:

θ = 56°

Step-by-step explanation:

As OA and OB are both radii, triangle AOB is an isosceles triangle:

⇒ m∠ABO = m∠OAB = 48°

Interior angles of a triangle sum to 180°:

⇒ m∠ABO + m∠OAB + m∠AOB = 180°

⇒ 48° + 48° + m∠AOB = 180°

⇒ m∠AOB = 180° - 48° - 48°

⇒ m∠AOB = 84°

Angles on a straight line sum to 180°:

⇒ m∠AOB + m∠DOB = 180°

⇒ 84° + m∠DOB = 180°

⇒ m∠DOB = 180° - 84°

⇒ m∠DOB = 96°

The tangent of a circle is always perpendicular to the radius.

Therefore, tangent BC is perpendicular to radius OB, and tangent DE is perpendicular to radius OD, so:

OBCD is a quadrilateral.

The interior angles of a quadrilateral sum to 360°:

⇒ m∠OBC + m∠BCD + m∠CDO + m∠DOB = 360°

⇒ 90° + θ + 28° + 90° + 96° = 360°

⇒ θ + 304° = 360°

⇒ θ = 360° - 304°

⇒ θ = 56°

For the following data of group of Scandinavians consisting of Swedes, Finns and Norwegians the probability for the following parts will be:

By using the formula, Circular permutation  = (n-1)

Total permutations = 18 - 1 = 17

(a) all the swedes sit together

Total permutations where all the swedes sit together  

= 13 x 5

all swedes sitting on 5 consecutive seats so they can be arranged  times and everyone including Norwegians as a group can be arranged in

Probability that all the swedes sit together = [tex]\frac{13 X 5}{17}[/tex]

(b) that all the Finns and all the Swedes sit together

Total permutations where all the Finns and all swedes sit together =  8 x 6 x 5

Probability that all the Finns and all swedes sit together = [tex]\frac{8 X 6 X 5}{17}[/tex]

(c) that all the Norwegians, Swedes, and Finns sit together.

Total permutations where all the Norwegians, Swedes, Finns sit together = (3-1)

So Probability that all the Norwegians, Swedes, Finns sit together = [tex]\frac{2 X 6 X 5 X 7}{17}[/tex]

The Central Limit Theorem establishes that the sampling distribution of the sample means of size n can be approximated to a normal distribution with mean and standard deviation s = /n for a normally distributed random variable X, with mean and standard deviation.

The Central Limit Theorem can also be used with skewed variables if n is at least 30.

The sampling distribution of the sample percentage for a proportion p in a sample of size n will be about normal, with mean and standard deviation s = p(1-p)/n.

The mean is the difference between the means when two normal variables are subtracted, and the standard deviation is the square root of the sum of the variances.

Average gas mileage (A): Mean 36, SD 6, sample size 50:

So, μA = 36, sA = 6/√50 = 0.8485

Gas mileage B: Mean 42, SD 8, and sample size of 50:

So, μB = 42, sB = 8/√50 = 1.1314

Arrangement of the difference:

Mean: 36 - 42 = -6 where A - B

Standard deviation: 1.4142

Locate the point estimate.

This is the mean difference, which is -6 mpg.

To determine our level, we must deduct 1 from the confidence interval and divide the result by two. So: 1 - 0.95/2 = 0.025

Now that z has a pvalue of, we must locate it in the Ztable.

Z = 1.96 since it has a pvalue of.

Identify the margin of error M as follows.

M = zs = 1.96 * 1.4142 = 2.77

2.77 mpg is the error margin.

The sample mean plus M determines the interval's upper end. Therefore, it is -6 + 2.77 = -3.23 mpg.

The difference between the population mean gas mileage for engines A and B and how to interpret the data, in mpg, have a 95% confidence interval of (-8.77, -3.23) means, whereas the standard deviation is the sum of the variances' square roots.

The [tex]n^{th[/tex] term of an exponentially increasing sequence can be found using the formula:

[tex]a_n = a_1[/tex] × [tex]r^(^n^-^1^)[/tex]

To find the [tex]n^{th[/tex] term of a sequence, you can use a formula that defines the relationship between the terms of the sequence. In this particular sequence, the terms seem to be increasing exponentially, with each term being the square of the previous term.

The [tex]n^{th[/tex] term of an exponentially increasing sequence can be found using the formula:

[tex]a_n = a_1[/tex] × [tex]r^(^n^-^1^)[/tex]

where [tex]a_n[/tex] is the nth term of the sequence, [tex]a_1[/tex] is the first term of the sequence, and r is the common ratio.

In this case, the first term is 2, and the common ratio is the previous term divided by the term before it. In this sequence, the common ratio is [tex]\frac{4}2=2[/tex]

Therefore, the [tex]n^{th}[/tex] term of the sequence can be found using the following formula:

[tex]a_n = 2[/tex] × [tex]2^{(n-1)[/tex]

So to find the [tex]n^{th[/tex] term, you would plug in the value of n into the formula. For example, to find the fifth term of the sequence, you would plug in 5 for n:

[tex]a_5 = 2[/tex] × [tex]2^{(5-1)[/tex]

= 2 × [tex]2^4[/tex]

= 2 × 16 = 32

So the fifth term of the sequence is 32
