The z-score for P(? ≤ z ≤ ?) = 0.60 is approximately 0.25.

The z-score for P(z ≥ ?) = 0.30 is approximately -0.52.

How to find the Z score

P(Z ≤ z) = 0.60

We can use a standard normal distribution table or a calculator to find that the z-score corresponding to a cumulative probability of 0.60 is approximately 0.25.

Therefore, the z-score for P(? ≤ z ≤ ?) = 0.60 is approximately 0.25.

For the second question:

We want to find the z-score such that the area under the standard normal distribution curve to the right of z is 0.30. In other words:

P(Z ≥ z) = 0.30

Using a standard normal distribution table or calculator, we can find that the z-score corresponding to a cumulative probability of 0.30 is approximately -0.52 (since we want the area to the right of z, we take the negative of the z-score).

Therefore, the z-score for P(z ≥ ?) = 0.30 is approximately -0.52.

The mode is one of the measures of central tendency in statistics. It represents the number that appears most frequently in a given list of numbers. In the example above, the mode for the list of numbers {5, 9, 12, 11, 12, 19, 18} is 12.

The mode is defined as the number that occurs most frequently in a list of numbers. In a set of numbers, there can be one mode, more than one mode, or no mode at all.

To find the mode for the list of numbers {5, 9, 12, 11, 12, 19, 18}, we need to identify the number that appears most frequently. Here, we can observe that 12 is the number that appears twice, while all the other numbers only appear once.

Therefore, the mode for this list of numbers is 12. It's important to note that if there are multiple numbers that appear with the same highest frequency, then all of them are considered as modes. For instance, if the list of numbers was {5, 9, 12, 11, 12, 19, 19, 18}, then both 12 and 19 would be modes since they each appear twice.

In conclusion, the mode is one of the measures of central tendency in statistics. It represents the number that appears most frequently in a given list of numbers. In the example above, the mode for the list of numbers {5, 9, 12, 11, 12, 19, 18} is 12.

Answer:

Exact Form:

45/44

Decimal Form:

1.0227

Mixed Number Form:

1  1/44

Step-by-step explanation:

Answer:

45/44 or 1  1/44

Step-by-step explanation:

\(5\frac{5}{8}\) ÷ \(5\frac{1}{2}\)

Change each mixed number into an improper fraction. Multiply the whole number by the denominator and add the numerator. This number becomes the new numerator and is put over the original denominator.

\(5\frac{5}{8} = \frac{45}{8}\)

\(5\frac{1}{2} = \frac{11}{2}\)

So now we can rewrite the expression as follows.

\(\frac{45}{8}\) ÷ \(\frac{11}{2}\)

Dividing by a fraction is the same thing as multiplying by its reciprocal. So rewrite the expression multiplying by 2/11 instead of dividing by 11/2.

\(\frac{45}{8}\) × \(\frac{2}{11}\)

Cross-cancel to simplify prior to solving the expression.

\(\frac{45}{8} * \frac{2}{11} = \frac{45}{4} * \frac{1}{11}\)

Solve the expression by mutiplying straight across.

\(\frac{45}{4} * \frac{1}{11} = \frac{45}{44}\)

So the original expression is equal to 45/44. If the answer is supposed to be a mixed number, divide the numerator by the denominator, and write the remainder as a fraction. So 45/44 also equals 1 and 1/44.

The exact value  of \(sin 2x\) is \(4√5/9.\)

Given that \(sec x = 3/2 and csc y = 3\)where x and y are in the 2x = 2 sin x quadrant, we need to find the exact value of sin 2x.

In the first quadrant, we have the following values of the trigonometric ratios:\(cos x = 2/3 and sin y = 3/5\)

Also, we know that sin \(2x = 2 sin x cos x.\)

Now, we need to find sin x.

Having sec x = 3/2, we can use the Pythagorean identity

\(^2x + 1 = sec^2xtan^2x + 1 = (3/2)^2tan^2x + 1 = 9/4tan^2x = 9/4 - 1 = 5/4tan x = ± √(5/4) = ± √5/2\)

As x is in the first quadrant, it lies between 0° and 90°.

Therefore, x cannot be negative.

Hence ,\(tan x = √5/2sin x = tan x cos x = √5/2 * 2/3 = √5/3\)

Now, we can find sin 2x by using the value of sin x and cos x derived above sin \(2x = 2 sin x cos xsin 2x = 2 (√5/3) (2/3)sin 2x = 4√5/9\)

Therefore, the exact value  of sin 2x is 4√5/9.

Step-by-step explanation:

A)

the domain of a function is the interval or set of all valid values for the input variable (the parameter of the function) - in our case here "n".

as the description says, "n" is the number of days observing the growth of the plant.

so, what are useful values for the number of observation days ?

negative numbers ? no, for sure not.

0 ? yes, as the starting size of the plant, when the study began.

and greater than 0 ? yes, up to the n, where the functional value reaches 11.04.

beyond that ? no, because it does not make any sense, as nobody was checking, if the curve still fits. and a plant for sure will not grow to infinity.

so, the interval is [0, x].

and x is the solution for n of

11.04 = 10(1.02)^n

1.104 = (1.02)^n

\( log_{1.02}(1.104) = n\)

and to calculate that with our calculators we know that

\( log_{b}(a) = \frac{ log_{c}(a) }{ log_{c}(b) } \)

so, let's simply use log to the base of c=10 :

\( \frac{ log(1.104) }{ log(1.02) } = n\)

n = 0.042969073... / 0.008600172... = 5

the study ended after day 5.

therefore, the domain interval is [0, 5]

B)

I answered this already under A.

the y-intercept is the point of n=0, and it is the starting size of the plant, when the study began (day 0).

C)

the average rate of change of a function in an interval [begin, end] is simply

(f(end) - f(begin)) / (end - begin)

in our case

begin = 1

end = 5

(f(5) - f(1))/(5-1) = (10(1.02)⁵ - 10(1.02)¹)/4 = (11.04 - 10.2)/4 =

= 0.84/4 = 0.21

that means the plant grew as average 0.21 cm per day during that observation period between day 1 and day 5.

The derivative of the function f(x) = √x can be found using the definition of the derivative. Therefore, using the definition of the derivative, the derivative of f(x) = √x is f'(x) = 1 / (2√x).

The definition of the derivative of a function f(x) at a point x is given by the limit:

f'(x) = lim (h->0) [f(x+h) - f(x)] / h

Applying this definition to the function f(x) = √x, we have:

f'(x) = lim (h->0) [√(x+h) - √x] / h

To simplify this expression, we can use a technique called rationalization of the denominator. Multiplying the numerator and denominator by the conjugate of the numerator, which is √(x+h) + √x, we get:

f'(x) = lim (h->0) [√(x+h) - √x] / h * (√(x+h) + √x) / (√(x+h) + √x)

Simplifying further, we have:

f'(x) = lim (h->0) [(x+h) - x] / [h(√(x+h) + √x)]

Canceling out the terms and taking the limit as h approaches 0, we get:

f'(x) = lim (h->0) 1 / (√(x+h) + √x)

Evaluating the limit, we find that the derivative of f(x) = √x is:

f'(x) = 1 / (2√x)

Therefore, using the definition of the derivative, the derivative of f(x) = √x is f'(x) = 1 / (2√x).

Step-by-step explanation:

The function is concave up for  x < 1 and concave down for x > 1 because the second derivative is positive for x < 1 and negative for x > 1. As a result, the critical point at x  < 1 is a relative maximum.

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is common to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. A function is an equation that depicts the connection between an input x and an output y, with precisely one output for each input. Another name for input is domain, while another one for output is range.

Here,

The derivative of the function f(x) can be found by taking the derivative of the expression e^(-x) (x^2 + 2x) using the product rule:

f'(x) = -e^(-x) (x^2 + 2x) + e^(-x) (2x + 2) = 2e^(-x) - 2xe^(-x) (x + 1)

Setting f'(x) equal to zero and solving for x gives us the critical points:

0 = 2e^(-x) - 2xe^(-x).(x + 1)

2xe^(-x).(x + 1) = 2e^(-x)

x(x + 1) = e^x

x^2 + x - e^x = 0

Next, we determine the concavity of the function at the critical points by analyzing the second derivative of the function:

f''(x) = 2e^(-x) + 2xe^(-x) + 2xe^(-x).(x + 1) - 2e^(-x).(x + 1)

= 2e^(-x).(1 - x)

Since the second derivative is positive for x < 1 and negative for x > 1, the function is concave up for x < 1 and concave down for x > 1. Thus, the critical point at x < 1 corresponds to a relative maximum.

Angle BCD intercepted arc is Arc DEB.

We know DE measure but we need to find EB measure.

Since a circle circumference add up to 360, we can add all of the known arcs up to 360 to find the missing arc.

\(73 + 53 + 102 + x = 360\)

\(126 + 102 + x = 360\)

\(228 + x = 360\)

\(x = 132\)

So arc EB measure 132.

Arc eb and de.

Angle BCD is inscribed angle of Arc DEB, so that means angle BCD is half of Arc DEB.

x² - x - 12

Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)

The factors are - 4 and + 3 , since

- 4 × 3 = - 12 and - 4 + 3 = - 1 , then

x² - x - 12 = (x - 4)(x + 3) ← in factored form

Answer:

B and D

Step-by-step explanation:

If you call s=-1 the coefficient of x and p=-12 the constant term, you must find two numbers whose sum is s and product is p.

In this case the two numbers are -4 and +3 in fact:

(-4)+(+3)=-1=s

(-4)*(+3)=-12=p

The polynomial can therefore be written as

(x-4)(x+3)

If you want to check this result, just multiply and get:

(x-4)(x+3)=x^2+3x-4x-12=x^2-x-12

Earl should order 60 reams of yellow paper and 40 reams of white paper to meet his requirement of 100 reams total and stay within his budget of $560.

Let's assume Earl orders x reams of yellow paper and y reams of white paper.

According to the given information:

Yellow paper cost: $5.00 per ream

White paper cost: $6.50 per ream

Total reams ordered: 100

Total budget: $560

We can set up the following equations based on the given information:

Equation 1: x + y = 100 (Total reams ordered)

Equation 2: 5x + 6.50y = 560 (Total cost within budget)

We can use these equations to solve for x and y.

From Equation 1, we can express x in terms of y:

x = 100 - y

Substituting this value of x into Equation 2:

5(100 - y) + 6.50y = 560

500 - 5y + 6.50y = 560

1.50y = 60

y = 40

Substituting the value of y back into Equation 1:

x + 40 = 100

x = 60

Therefore, Earl should order 60 reams of yellow paper and 40 reams of white paper to meet his requirements and stay within his budget.
