Answer: the answer is 28

Step-by-step explanation: 28 is divisible by 7 and it is a even number

The summary of the given data is Min = 44, Q1 = 48, Median = 50.5, Q3 = 53, Max = 56  . So option C is correct.

The middle  number of data in a collection is known as the median. Three alternative metrics are employed in mathematics to determine the average value for a given group of integers. They are the median,  mode, and mean. The measures of central tendency are this trio of measurements.

Median = [(n/2)th term + {(n/2)+1}th term]/2 (for even)

Median = {(n+1)/2}th term (for odd)

Based on the given information,

we can see that the box plot shows the values of 44, 48, 50.5, 53, and 56.

These values represent the minimum, lower quartile (Q1), median, upper quartile (Q3), and maximum, respectively.

Therefore, the five-number summary for this data is:

Min = 44,

Q1 = 48,

Median = 50.5,

Q3 = 53,

Max = 56

So the answer is: Min = 44, Q1 = 48, Median = 50.5, Q3 = 53, Max = 56

The stronger one is 4 scoops of coffee for 6 cups of water.

Strong coffee is prepared by employing a greater coffee grounds-to-water ratio. Typically, 2 teaspoons of coffee grinds are used for every 6 ounces of water in a strong cup of coffee. To make a truly strong cup of coffee, use 3 teaspoons of ground coffee for every 6 ounces of water. If you use a French press, you need also increase the steeping time.

In the given question, it is stronger to use 4 scoops of coffee for 6 glasses of water. This is due to the fact that there are more coffee grounds in relation to the amount of water, resulting in a higher concentration of coffee in the combination.

On solving the provided question, we can say that  The following are the mean and standard deviation of the sample distribution of x: Average: 225 sec. 19 second standard deviation.

Standard deviation is a statistic that expresses the variability οr variance of a grοup of numbers. While a high standard deviation suggests that the values are mοre dispersed, a low standard deviation suggests that the values tend tο be closer to the established mean.

A measure of hοw dispersed the data are frοm the mean is the standard deviation (οr ). When the standard deviation is lοw, the data tend to be grouped around the mean, and when it is large, the data are mοre dispersed. The average variability of the data set is measured as standard deviation. It reveals the average deviation of each scοre from the mean.

The median matches the median οf the population.

The pοpulation standard deviation is divided by the square root of the sample size tο produce the standard deviation.

The following are the criteria fοr this issue:

average population of 225 seconds.

60 second population standard deviatiοn.

Answer:

The function for the given zeros is f(x)=2x³-8x²+8x-32.

The zeros of polynomial refer to the values of the variables present in the polynomial equation for which the polynomial equals 0.

Given that, n=3.

x=4 and x=2i

We then know that the third root must be x=-2i

Now, f(x)=a(x-4)(x-2i)(x+2i)

= a(x-4)(x²-(-2i)²)

= a(x-4)(x²-(-4))

= a(x-4)(x²+4)

= ax²(x-4)+4(x-4)

f(x)= a(x³-4x²+4x-16)

f(1)=a(1³-4×1²+4×1-16)

-30=a(1-4+4-16)

a=2

Now, f(x)=2(x³-4x²+4x-16)

f(x)=2x³-8x²+8x-32

Therefore, the function is f(x)=2x³-8x²+8x-32.

7/8 of sixteen times a half of 30 is 210.

What is a PEMDAS rule?

PEMDAS is an acronym that stands for the order of operations in mathematics: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

To calculate this, we can follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

Start with the expression inside the parentheses: half of 30 is 15.

Multiply 16 by 15: 16 times 15 is 240.

Find 7/8 of 240:

7/8 of 240 = (7/8) x 240

The number of years the interest was compounded quarterly is given by the equation b = 9.098 years

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

Let the amount after b years be A = $ 26,725.00

The number of years be = b

The number of times the interest is applies n = 4 ( quarterly )

Let the principal amount be P = $ 7,000

A = P ( 1 + r/n )ⁿᵇ

Substituting the values in the equation , we get

t = ln ( A/P ) / n [ ln ( 1 + r/n ) ]

t = b = n ( 26,725.00 / 7,000.00 ) / ( 4 × [ ln ( 1 + 0.15/4 ) ] )

On simplifying the equation , we get

b = ln ( 26,725.00 / 7,000.00 ) / ( 4 × [ ln ( 1 + 0.0375 ) ] )

b = ln ( 3.81785714 ) / 4 [ ln ( 1.0375 ) ]

On further simplification , we get

b = 9.098 years

Hence , the number of years the interest was applied is 9 years 1 months

The required equation of the line representing line CD is y = x + 2. Option C is correct.

The equation of the line passing through two points is given by the equation,

y - y₁ = (y₂ - y₁) / (x₂ - x₁) (x - x₁)  - - - -- -(1)

Here,
Line CD passes through points (0, 2) and (4, 6)
Let (0, 2) and (4, 6) equal to (x₁, y₁) and (x₂, y₂) respectively.
Substitute this point in equation 1 to get the equation of the line representing CD,

So,
y - 2 = (6 - 2)/(4-0) (x - 0)
y = x + 2

Thus, the required equation of the line representing line CD is y = x + 2. Option C is correct.

So, r= 5.8%

r = 0.058

Now, the time taken to double the sample then P(t) = 2P(0).

By making the discriminant equal to zero, we can see that the quadratic equation has one real solution only for z = 10.

For a general quadratic equation:

a*x^2 + b*x + c = 0

We define the discriminant as:

D = b^2 - 4ac

The quadratic equation will have only one real solution only if the discriminant is equal to zero.

Here the quadratic is:

(z - 5)*x^2 - z*x + 5 = 0

Then the discriminant is:

(-z)^2 - 4*5*(z - 5)

And that must be equal to zero, then we need to solve:

z^2 - 20*(z - 5) = 0

z^2 - 20z + 100 = 0

Using the quadratic formula we will get:

[tex]z = \frac{20 \pm \sqrt{(-20)^2 - 4*1*100} }{2} \\\\z = \frac{20 \pm 0}{2} \\\\z = 10[/tex]

The SSS Similarity Theorem states that two triangles are similar if the ratio of all three pairs of corresponding sides of two triangles are equivalent.

Given ΔUVW and ΔXYZ, where:

UV corresponds with XY, thus UV/XY = 50/40 = 1.25

WU corresponds with ZX, thus WU/ZX = 40/32 = 1.25

WV corresponds with ZY, thus WV/ZY = 60/48 = 1.25

Since all the ratio of all three corresponding sides of both triangles are equivalent, therefore both triangles can be proven to be similar by the SSS Similarity Theorem.
