The purpose of using prefix in the metric system is to properly sale the basis of the unit so large numeric values can be used effectively.

If the metric system is not properly prefixed it can lead to various inconsistencies in the the numeric values. for example if you go to a computer store and you do not know the scale like (kb, mb, gb, tb) you will get quite confused about what is the sales representative saying

Consider you went to a store to get sugar and you do not know the metric system say(gram, kg, mg) you would not know how much sugar you need directly by taking it in your hands.

Answer:

\(\frac{4}{9}\)

\(-\frac{9}{4}\)

Step-by-step explanation:

First, solve the equation for y to find the slope of the original line. When you solve for y you get \(y=-\frac{9}{4}x+2\). Since the coefficient of x in slope-intercept form is the slope, -9/4 is the slope of this line.

Perpendicular lines have the opposite slope, so if the slope is a/b then the perpendicular slope is -b/a. Since the slope is -9/4, the perpendicular slope is 4/9.

Parallel lines have the same slope. So, the slope is the exact same, -9/4.

Step-by-step explanation:

The kinetic energy per mole of gaseous NH3 molecules at 366.6 Kelvin is approximately 13.5046 kJ/mol.

The kinetic energy per mole of gaseous NH3 molecules at 366.6 Kelvin can be calculated using the formula:
Kinetic energy per mole = (3/2) * R * T
where R is the gas constant (8.314 J/(mol·K)) and T is the temperature in Kelvin.
In this case, the given temperature is 366.6 Kelvin. We can substitute the values into the formula:

Kinetic energy per mole = (3/2) * (8.314 J/(mol·K)) * 366.6 K

Now, we can calculate the result:
Kinetic energy per mole = (3/2) * 8.314 J/(mol·K) * 366.6 K

= 36.8766 J/(mol·K) * 366.6 K

= 13,504.5996 J/mol

To convert this result to kJ/mol, we divide by 1000:
13,504.5996 J/mol / 1000 = 13.5046 kJ/mol

Therefore, the kinetic energy per mole of gaseous NH3 molecules at 366.6 Kelvin is approximately 13.5046 kJ/mol.

The 88.5 ft² fabric of each color will be needed to make a single parachute canopy.

Given

The canopy of a parachute is a semicircle with a radius of 13 feet.

A company that is making parachutes for a Fourth of July celebration wants each parachute to be made from equal parts of red, white, and blue fabric.

The area of a semicircle is half of the area of the circle.

The first step is the surface area of the semicircle.

The surface area of a circle is;

\(\rm Surface \ area=\pi r^2\\\\Surface \ area=3.14 \times 13^2\\\\Surface \ area =530.929\)

Since the semicircle, we divide this by 2.

S.A of the parachute is;

\(\rm =\dfrac{530.929}{2}\\\\= 265.4645\)

To get the fabric is needed for each color we divide this by 3.

The fabric needed for each color is;

\(\rm= \dfrac{265.4645}{3}\\\\=88.5\)

Hence, the 88.5 ft² fabric of each color will be needed to make a single parachute canopy.

The probability that fewer than 7 out of 10 students will be carrying backpacks is approximately 0.00736, or 0.736%.

To solve this problem, we can use the binomial probability distribution. The probability distribution for a binomial random variable is given by:

\(\[P(X=k) = \binom{n}{k} p^k (1-p)^{n-k}\]\)

Where:

- \(\(P(X=k)\)\) is the probability of getting exactly \(\(k\)\) successes

- \(\(n\)\) is the number of trials

- \(\(p\)\) is the probability of success in a single trial

- \(\(k\)\) is the number of successes

In this case, the probability that an Oxnard University student is carrying a backpack is \(\(p = 0.70\)\). We want to find the probability that fewer than 7 out of 10 students will be carrying backpacks, which can be expressed as:

\(\[P(X < 7) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6)\]\)

If we assume that the probability (p) of a student carrying a backpack is 0.70, we can proceed to calculate the probability that fewer than 7 out of 10 students will be carrying backpacks.

Let's substitute the given value of p into the individual probabilities and calculate them:

\(\[P(X=0) = \binom{10}{0} \cdot (0.70)^0 \cdot (1-0.70)^{10-0}\]\)

\(\[P(X=1) = \binom{10}{1} \cdot (0.70)^1 \cdot (1-0.70)^{10-1}\]\)

\(\[P(X=2) = \binom{10}{2} \cdot (0.70)^2 \cdot (1-0.70)^{10-2}\]\)

\(\[P(X=3) = \binom{10}{3} \cdot (0.70)^3 \cdot (1-0.70)^{10-3}\]\)

\(\[P(X=4) = \binom{10}{4} \cdot (0.70)^4 \cdot (1-0.70)^{10-4}\]\)

\(\[P(X=5) = \binom{10}{5} \cdot (0.70)^5 \cdot (1-0.70)^{10-5}\]\)

\(\[P(X=6) = \binom{10}{6} \cdot (0.70)^6 \cdot (1-0.70)^{10-6}\]\)

Now, let's calculate each of these probabilities:

\(\[P(X=0) = \binom{10}{0} \cdot (0.70)^0 \cdot (1-0.70)^{10-0} = 0.0000001\]\)

\(\[P(X=1) = \binom{10}{1} \cdot (0.70)^1 \cdot (1-0.70)^{10-1} = 0.0000015\]\)

\(\[P(X=2) = \binom{10}{2} \cdot (0.70)^2 \cdot (1-0.70)^{10-2} = 0.0000151\]\)

\(\[P(X=3) = \binom{10}{3} \cdot (0.70)^3 \cdot (1-0.70)^{10-3} = 0.000105\]\)

\(\[P(X=4) = \binom{10}{4} \cdot (0.70)^4 \cdot (1-0.70)^{10-4} = 0.000489\]\)

\(\[P(X=5) = \binom{10}{5} \cdot (0.70)^5 \cdot (1-0.70)^{10-5} = 0.00182\]\)

\(\[P(X=6) = \binom{10}{6} \cdot (0.70)^6 \cdot (1-0.70)^{10-6} = 0.00534\]\)

Finally, we can substitute these probabilities into the formula and calculate the probability that fewer than 7 out of 10 students will be carrying backpacks:

\(\[P(X < 7) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6)\]\)

\(\[P(X < 7) = 0.0000001 + 0.0000015 + 0.0000151 + 0.000105 + 0.000489 + 0.00182 + 0.00534\]\)

Evaluating this expression:

\(\[P(X < 7) \approx 0.00736\]\)

Therefore, the probability that fewer than 7 out of 10 students will be carrying backpacks is approximately 0.00736, or 0.736%.

In this case, since we want the sample mean to be within 0.01 of the population mean, the margin of error is 0.01.

To determine the number of grade-point averages needed to have a sample mean within 0.01 of the population mean, we can use the formula for the margin of error. The margin of error is calculated by dividing the standard deviation of the population by the square root of the sample size, multiplied by a constant value.

To find the required sample size, we need to know the standard deviation of the population. However, since it is not provided, we cannot calculate the exact number of grade-point averages needed.
If you have the standard deviation of the population, you can use the following formula to calculate the sample size:
Sample size = (Z * standard deviation) / margin of error

Where Z is the constant value that corresponds to the desired level of confidence. For example, if you want a 95% confidence level, Z would be approximately 1.96.

Answer:

112 degrees

Step-by-step explanation:

This is a quadrilateral, meaning 4 sides. The sum of the angles of a quadrilateral is 360 degrees. You are given the right angle, or 90 degrees, and the 46 degree angle at the bottom. Since the two lines on either side of the 46 degree angle represent parallelism, angles 1 and 2 are the same.

360 - (90+46) = 224.

224 / 2 = 112.

Answer:

\(m∠1 = 112\)

Step-by-step explanation:

\(m∠1 = m∠2\)

\(m∠1 + m∠2 + 90 + 46 = 360\)

\(m∠1 +m ∠2 + 136 = 360\)

\(m∠1 + m∠2 = 360 - 136\)

\(m∠1 + m∠2 = 224\)

\(m∠1 = \frac{224}{2} \)

\(m∠1 = 112\)

\(m∠2 = \frac{224}{2} \)

Given that John climbs a height of \($(x + 5)$\) miles in \($(x - 1)$\) hours and Jane climbs a height of \($(x + 11)$\) miles in \($(x + 1)$\) hours. We know that the distance covered by both John and Jane are equal.

Distance covered by John = Distance covered by Jane

Therefore, \($(x + 5) = (x + 11)$\)

Thus, x = 6

Now, we need to find the speed of both, which is given by the formulae:

Speed = Distance / Time

So, speed of John = \($(x + 5) / (x - 1)$\) Speed of John =\($11 / 5$\) mph

Similarly, speed of Jane = \($(x + 11) / (x + 1)$\)

Speed of Jane = \($17 / 7$\) mph

Since both have to be equal, Speed of John = Speed of Jane Therefore,

\($(x + 5) / (x - 1) = (x + 11) / (x + 1)$\)

Solving this equation we get ,x = 2Speed of John = \($7 / 3$\) mph

Speed of Jane = \($7 / 3$\) mph

Thus, their speed was \($7 / 3$\) mph.

The Residual is defined as the difference between the actual and predicted, or fitted values of the response variable. This statement is true.

Linear regression is a statistical tool that determines how well a straight line fits a set of paired data. The straight line that best fits that data is called the least squares regression line. This line can be used in a number of ways. One of these uses is to estimate the value of a response variable for a given value of an explanatory variable. Related to this idea is that of a residual.

Residuals are obtained by performing subtraction. All that we must do is to subtract the predicted value of y from the observed value of y for a particular x. The result is called a residual.

The formula for residuals is straightforward:

Residual = observed y – predicted y

It is important to note that the predicted value comes from our regression line. The observed value comes from our data set.
