Answer:

\(\approx 45.1\:\mathrm{w/\: some \: MOE}\)

Step-by-step explanation:

The area of \(ABCD\) is comprised of two triangles, so we can find the area of both triangles and add them to get the total area of

Since the sum of the interior angles of a triangle add up to \(180^{\circ}\), we have:

\(\angle C=180-44-38=\fbox{$98^{\circ}$}\).

The Law of Sines is given as:

\(\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}\) for any triangle.

Therefore, we have the proportion:

\(\frac{\sin 98^{\circ}}{10}=\frac{\sin 44^{\circ}}{BC},\\BC=\frac{10\cdot \sin 44^{\circ}}{\sin 98^{\circ}},\\BC\approx 7.01\).

Now that we have two sides of a triangle and the angle between them, we can use \([\triangle]=\frac{1}{2}ab\sin C\)  to find the area of \(\triangle CBD\):

\([CBD]=\frac{1}{2}\cdot 10\cdot 7.01 \cdot \sin 38^{\circ},\\\\\left [CBD]\right\approx 21.58\).

Since \(\triangle ABD\) is a right triangle, we can use basic trig rules for a right triangle to solve for the sides:

\(\sin 55^{\circ}=\frac{AB}{10},\\AB=10\sin 55^{\circ},\\AB\approx 8.19\),

\(\sin 35^{\circ}=\frac{AD}{10},\\AD=10\sin 35^{\circ},\\AD\approx 5.74\).

Therefore, the area of \(\triangle ABD\) is:

\(\frac{1}{2}\cdot 8.19\cdot 5.74\approx 23.49\).

The area of \(ABCD\) is then

\(21.58+23.49=45.07=\fbox{$45.1$}\).

\(\bigstar\) Note that intermediate results were rounded during this calculation. Therefore, there is a small margin of error when rounding to final answer to one decimal place. I recommend plugging in values for yourself using all equations I wrote above, then rounding only your final answer to one decimal place as requested by the problem.

The mean of the sampling proportion is 0.03 and the standard deviation of the sampling proportion is 0.008 if the probability that a student forgets to bring their ID with them when they take their SAT is 3%. and a random sample of 500 students was selected.

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

We have:

p = 0.03

n = 500 students

\(\rm {\hat p} - Normal\)

So the mean:

\(\rm \mu _\hat p \ = \ p \ = \ 0.03\)

For standard deviation:

\(\rm \sigma_p = \sqrt{\frac{pq}{m} }\)

q = 1 - p = 1 - 0.03 = 0.97

\(\rm \sigma_p = \sqrt{\frac{0.03\times 0.97}{500} }\)

\(\rm \sigma_p = 0.008\)

Thus, the mean of the sampling proportion is 0.03 and the standard deviation of the sampling proportion is 0.008 if the probability that a student forgets to bring their ID with them when they take their SAT is 3%. and a random sample of 500 students was selected.

Answer:

X < 5, or 5 > X

Step-by-step explanation:

Open up the parenthesis on the left side

-8 < 32 - 8x

Isolate -8x

- 8 - 32 < -8x
We can rewrite the inequality to make it easier to solve

-8x > -8 - 32

Answer:

What is the quotient (3x2 + 4x - 15) ÷ (x + 3)? Summary: The quotient of (3x2 + 4x - 15) ÷ (x + 3) is 3x - 5.

Step-by-step explanation:

Answer:

20 m by 10 m

Step-by-step explanation:

let w be width and l be length , then

2(l + w) = 60 ( divide both sides by 2 )

l + w = 30 ( subtract w from both sides )

l = 30 - w → (1)

lw = 200 → (2)

Substitute l = 30 - w into (2)

w(30 - w) = 200 ← distribute parenthesis on left side

30w - w² = 200 ( subtract 200 from both sides )

30w - w² - 200 = 0 ( multiply through by - 1 )

w² - 30w + 200 = 0 ← in standard form

(w - 10)(w - 20) = 0 ← in factored form

Equate each factor to zero and solve for w

w - 10 = 0 ⇒ w = 10

w - 20 = 0 ⇒ w = 20

Substitute these values into (1)

l = 30 - 10 = 20

l = 30 - 20 = 10

dimensions of field is 20 m by 10 m

Answer:

THIS IS THE REPRENTATION :I(LENGTH ),W(WIDTH)

2IW= 200

I,II USE THE SUBSTITUTION METHOD SINCE :I=30-W WE CAN SUBSTITUTE THE LENGTH TO 30

-W TO IW=200

(30-W)W=200

W2 + 30W=200---------------TRANSPOSE -w2

+30w

w2-30w +200 = 0------------------- USE FACTORING

(W-20)(w-10 =0----------------- THEN EQUATE EACH FACTOR TO ZERO

W- 20=0 W-10 =0

W=20 W=10

THEN SUBSTITUTE THE VALUE OF w TO ANY OF THE EQUATIONS TO GET THE VALUE OF I

Iw =200 Iw=200

I(20) =200 I(10)

I(20)/20= 200/20 I(10)/10

=200/10

The required order for the three according to the turn of the audition is Heather, Jen, and bob.

Given that,
Jen, Heather, and Bob are auditioning for the same role. Jen auditions 10 minutes before four, Heather auditions 30 minutes before Jen, and Bob auditions 5 minutes before four. Order the three by who will audition first.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Let's order the timeline,

Jen's audition was 10 minutes before the 4, so the time is 3:50
Heather's audition was 30 minutes before so the time would be 3:20
Bob's audition was 5 minutes before the 4 so the time would be 3:55
So from the above calculation. the order of the audition is Heather, Jen, and bob.

Thus, the required order for the three according to the turn of the audition is Heather, Jen, and bob.

The sample mean is c) M=51.

To find the sample mean, we can use the formula for z-score:
                                              z = (X - M) / s

where:

In this case, we have two equations with two unknowns:

-0.25 = (M - 3 - M) / s
-0.75 = (44 - M) / s

Multiplying both sides of the first equation by s gives us:
-0.25s = M - 3 - M

Simplifying gives us:
-0.25s = -3

Next, we can multiply both sides of the second equation by s:
-0.75s = 44 - M

Now we can substitute the value of s from the first equation into the second equation:
-0.75(-3 / 0.25) = 44 - M

Simplifying gives us:
9 = 44 - M

Finally, we can solve for M:
M = 44 - 9
M = 35

So the sample mean is 35.

However, this answer is not one of the options given. It's possible that there was a mistake in the original question or in the calculations. Double-checking the calculations and the original question can help determine the correct answer. In this case, the correct answer is c. M=51.

A nurse researcher may choose to assign subjects randomly to groups in a study for various reasons.

Random assignment of subjects to groups is a fundamental technique in research design, particularly in experimental studies. Here are some reasons why a nurse researcher would choose to assign subjects randomly to groups:

1. Minimizing bias: Random assignment helps minimize selection bias by ensuring that each participant has an equal chance of being assigned to any group. This helps create comparable groups and reduces the influence of confounding variables.

2. Enhancing internal validity: Random assignment strengthens the internal validity of a study by increasing the likelihood that any observed differences between groups are due to the intervention or treatment being studied, rather than preexisting differences between individuals.

3. Facilitating statistical analysis: Random assignment allows for the use of inferential statistics, as it provides a basis for making generalizations and drawing conclusions about the population from the sample data.

4. Ensuring generalizability: Random assignment increases the generalizability or external validity of the findings, as it helps create groups that are representative of the target population, making it easier to apply the study's results to a broader context.

By employing random assignment, nurse researchers can enhance the rigor, reliability, and validity of their studies, thereby contributing to evidence-based practice and improving patient care.

Step-by-step explanation:

2a+4a = 6a

b-3b = -2b

-c-2c = -3c

-d+5d = 4d

Answer:

6a - b - 3c + 4d

Step-by-step explanation:

⭐What is a polynomial?

Whenever you add polynomials, the only terms you can perform addition or subtraction on are like terms.

⭐What are like terms?

We are asked to add the two given polynomials. Therefore, we have to add the like terms.

\(2a + b - c - d + (4a - 3b - 2c + 5d)\)

a and a, b and b, c and c, and d and d all have the same variable with an exponent of 1.

When adding, make sure to utilize the correct addition rules.

⭐What are the rules for adding real numbers?

2a and 4a are positive. Therefore, 2a + 4a = 6a.

-3b is negative, but b is positive. -3b > b. Therefore, -3b + b = -2b.

-c and -2c are both negative. Therefore, -2c - c = -3c.

-d is negative, but 5d is positive. 5d > -d. Therefore, -d + 5d = 4d.

∴ \(2a + b - c - d + (4a - 3b - 2c + 5d) = 6a -b -3c + 4d\)

When the probability is proportional to the length of the interval in which the random variable can assume a value, the random variable is uniformly distributed.

In probability theory and statistics, a uniformly distributed random variable follows a uniform distribution. This distribution occurs when the probability of the random variable assuming a value is equal across a given interval, and the probability is proportional to the length of that interval.
In a uniform distribution, every value within the interval has an equal likelihood of occurring. The probability density function (PDF) of a continuous uniform distribution is a constant within the interval and zero outside of it. The cumulative distribution function (CDF) is a linear function that increases uniformly from 0 to 1 over the interval.
For example, if we have a random variable representing the time it takes for a car to pass through a traffic light, and the probability of the car taking any specific amount of time is proportional to that time interval's length, then the random variable follows a uniform distribution.
Therefore, when the probability is proportional to the length of the interval in which the random variable can assume a value, the random variable is uniformly distributed.
