The congruent angles are:

Congruent angles are angles that have the same degree measurement. In other words, they are equal in size or angle measure. For instance, if one angle measures 45 degrees and another angle also measures 45 degrees, these two angles are congruent.

The symbol for congruence is ≅. So, if angle A is congruent to angle B, it is written as ∠A ≅ ∠B.

Answer:

d

Step-by-step explanation:

At 7 o' clock the minute hand is at 12 and the hour hand at 7

There is 360° in a complete revolution, thus between 7 and 12

angle = \(\frac{7}{12}\) × 360° = 7 × 30° = 210° → d

Answer:

Option D) Angle at 7 o'clock = 210 degrees

Step-by-step explanation:

The whole clock = 360 degrees

Every 1 hour = 360/12

Every 1 hour = 30 degrees

Angle at 7 o'clock = 30*7

Angle at 7 o'clock = 210 degrees

Determine which statement that justifies the similarities between ABC and A'B'C'

When ABC is dilated by a scale factor of 3 to form A'B'C', the sides A'B'C are 3 times as large as the sides of ABC.

However, all three angles of both triangles remain the same. This is so, because dilation do not affect angles.

So, a statement that can be used to justify the similarities is:  AA ≅ AA

To calculate the z-scores for the number of sags and swells for a selected transformer, we need the sample mean.

The sample standard deviation of the transformer's data, as well as the population mean and population standard deviation. Unfortunately, the specific values for these parameters are not provided in the question, making it impossible to calculate the z-scores accurately.

The z-score measures how many standard deviations a particular value is from the mean. It is calculated using the formula: z = (x - μ) / σ, where x is the observed value, μ is the mean, and σ is the standard deviation.

In this case, without the necessary data, we cannot calculate the z-scores accurately or provide interpretations of the z-scores. The z-scores would indicate how far the number of sags and swells for the selected transformer deviates from the mean, in terms of standard deviations. A positive z-score would suggest that the value is above the mean, while a negative z-score would indicate a value below the mean.

To accurately determine the z-scores and provide interpretations, we would need the specific values for the sample mean, sample standard deviation, population mean, and population standard deviation of the transformer's data.

The ratio of John's money to Peter's money is 5/4. This means if John has a total amount of 5 then Peter will have a total of 4 as his amount.

Let's assume John has 'x' amount of  money, Peter has 'y' amount of money, The money John saved is 'p' and the money Peter saved is 'q'

So,

p = x - 80x/100                (equation 1)

q = y - 75y/100                (equation 2)

According to the given question, the amount John saved is equal to the amount Peter saved. Hence, we can equate equations 1 and 2.

p = q

x- 80x/100 = y - 75y/100

x - 0.8x = y - 0.75y

0.2x = 0.25y

x =  0.25y/0.2

x/y = 0.25/0.2

x/y = 25/20

x/y = 5/4

Hence, the ratio of John's money to Peter's money is 5/4.

The arithmetic formula (C) (n)=-1+2n for n≥2 would represent the given arithmetic sequence 3,5,7,9,...

A progression or sequence of numbers known as an arithmetic sequence maintains a consistent difference between each succeeding term and its predecessor.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.

For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

An arithmetic progression is another name for an arithmetic sequence.

Using the method for locating the nth term, we can locate a particular term in an arithmetic series.

An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d.

Therefore, enter the values a = 2 and d = 3 into the formula to determine the nth term.

So, since in the given sequence, we know that:

3,5,7,9,..,

Common difference = 5 - 3 = 2

Then, n has to be 2.

Which is in option (C) where (n)=-1+2n for n≥2.

Therefore, the arithmetic formula (C) (n)=-1+2n for n≥2 would represent the given arithmetic sequence 3,5,7,9,...

The model having number of cell phone users in the city doubled every 10 years is an exponential function not a linear function.

Because it represents the growth rate exponentially.

Last year number of users of the cell phone in a city = 500

Number of cell phones users doubled every 10 years.

The model that represents the number of cell phone users in the city is an exponential function, not a linear function.

This is because the number of cell phone users is doubling every 10 years.

Which means that the rate of growth is increasing exponentially.

In an exponential function, the variable in the exponent increases or decreases at a constant rate.

It is the case here as the number of cell phone users is doubling at a constant rate of every 10 years.

The exponential function that represents the number of cell phone users in the city can be written as,

f(x) = 500 × \(2^{x/10}\)

where x is the number of years since the initial count of 500 cell phone users.

This function gives the number of cell phone users after x years,

And the exponent x/10 represents the doubling of the number of cell phone users every 10 years.

Therefore, the model represents the exponential function.

To prove ΔXWZ and ΔXYZ are congruent using sas congruence, ∠WXZ and ∠YXZ must be congruent.

In this question we have been given two triangles ΔXWZ and ΔXYZ.

We need to prove ΔXWZ and ΔXYZ are congruent using sas congruence.

To prove ΔXWZ and ΔXYZ are congruent using sas congruence we need

WX = XY                            ...........(given)      

∠W ≅ ∠Y                  

XZ  = XZ                            ..............(common side)

then ΔXWZ  ≅ ΔXYZ               ................(by SAS congruence rule)

By the SAS rule, the angle between the same side must be equal so ∠WXZ = ∠YXZ.

Find a figure associated to given question below.

The expression 60⋅1.2^t models the number of nano-related patents granted in the US as a function of years since 1991.


Start with the number 60.

This represents the initial number of nano-related patents granted in the US in the year 1991.

Multiply 60 by 1.2.

This accounts for a growth factor of 1.2, indicating that the number of patents granted is increasing by 20% each year.

Raise 1.2 to the power of t. The variable t represents the number of years since 1991. This allows the expression to model the increase in patents over time.

The resulting expression, 60⋅1.2^t, gives an estimate of the number of nano-related patents granted in the US for any given year since 1991.

The critical value for a 98% confidence interval with a sample size of n=30 and known standard deviation  is 2.756.

When constructing a confidence interval, the critical value represents the number of standard errors above and below the sample mean that encompasses the specified confidence level. A larger confidence level requires a larger critical value, and a larger sample size will generally result in a smaller critical value, assuming that the population standard deviation is known. In this case, with a sample size of 30 and a 98% confidence level, the critical value is calculated to be 2.756, rounded to 3 decimal places.
