The horses' average speeds are approximately:

(a) mi/s: 0.0102 mi/s

(b) mi/h: 58.06 mi/h

To calculate the horses' average speeds, we need to calculate the speed as distance divided by time.

We have:

Distance: 1.50 miles

Time: 147 seconds

(a) To calculate the average speed in mi/s, we divide the distance by the time:

Average speed = Distance / Time

Speed of Fiddle Isle = 1.50 miles / 147 seconds ≈ 0.0102 mi/s

Speed of John Henry = 1.50 miles / 147 seconds ≈ 0.0102 mi/s

(b) To calculate the average speed in mi/h, we need to convert the time from seconds to hours:

Average speed = Distance / Time

Since 1 hour has 3600 seconds, we can convert the time to hours:

Time in hours = 147 seconds / 3600 seconds/hour

Speed of Fiddle Isle = 1.50 miles / (147 seconds / 3600 seconds/hour) ≈ 58.06 mi/h

Speed of John Henry = 1.50 miles / (147 seconds / 3600 seconds/hour) ≈ 58.06 mi/h

18 root

2

Step-by-step explanation:

In this question imagine there is no y

It will be 10 root2 +5 root2 +3 root 2 it will be 18 root 2

Hey there! I'm happy to help!

SLOPE

To find the slope, you divide the difference of the y values by the difference in the x values.

10-(-2)=10+2=12

-6-(-3)=-6+3=-3

12/-3=-4

So, our slope is -4.

Y- INTERCEPT

To find the y-intercept, we plug our slope and one of our points into the slope intercept equation (y=mx+b) and solve for b, which is the y-intercept. We will use the point (-6,10).

10=-4(-6)+b

Flip the equation so b is on the left.

-4(-6)+b=10

24+b=10

Subtract 24 from both sides.

b=-14

Our y-intercept is -14.

EQUATION

The slope intercept equation is y=mx+b, where m is the slope and b is the y-intercept. Therefore, we have the following answers.

Slope: -4

y-Intercept: -14

Equation of the Line: y=-4x-14

The probability that the weight of a bag will be greater than the maximum allowable weight of 50 pounds depends on the distribution of bag weights and their relationship to the maximum weight limit.

To estimate the probability, we can assume a normal distribution for bag weights, with a mean and standard deviation. Let's denote the mean as μ and the standard deviation as σ. If we assume that bag weights follow a normal distribution, we can calculate the z-score for the maximum allowable weight of 50 pounds using the formula: z = (x - μ) / σ, where x is the maximum weight.

Next, we can use the z-score to determine the probability using the cumulative distribution function (CDF) of the standard normal distribution. The CDF gives the probability that a random variable is less than or equal to a certain value. In this case, we want to find the probability that the bag weight exceeds 50 pounds, which is equivalent to finding the probability that the random variable is greater than 50 pounds.

Since the CDF provides the probability of being less than or equal to a given value, we can subtract the result from 1 to obtain the probability of being greater than 50 pounds. This probability represents the likelihood of a bag exceeding the maximum allowable weight. However, keep in mind that these calculations are based on the assumption of a normal distribution, and the actual probability will vary depending on the specific characteristics of the bag weights distribution.

Answer:

It's the zero product property. The product must be equal to zero, nothing else.

Step-by-step explanation:

If (x + 2)(x - 4) = 72, it does not mean that each factor could be equal to 72.

The number 72 has many factors (they come in pairs), and they need not even be integers, 1/2 and 144, for example.

On the other hand, if  ab = 0, then either  a = 0  or  b = 0.

Kiran is incorrect because the product property only applies to products that are equal to zero.

Any equation of the form \(\rm ax^2+bx+c=0\)  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

We have:

(x+2)(x-4) = 0

According to zero product property either x+2 =0 or x-4 = 0

Now considering:

(x + 2)(x -4) = 72

It doesn't mean the x + 2 is equal to 72 or X-6 is equal to 72.

Because 72 may have different factors the zero product property the product must be zero.

Thus, Kiran is incorrect because the product property only applies to products that are equal to zero.

The given statement " When the film is placed into the XCP (extension cone paralleling) holder with the smooth side of the film towards the throat, after processing, it will appear darker" is false because it will  lighter, not darker.

The smooth side of the film is the side that interacts with the X-ray radiation and receives the image, while the emulsion side contains the light-sensitive crystals that react to the radiation.

Placing the smooth side towards the throat ensures that the image is sharp and clear, as the X-ray beam travels through the teeth and soft tissues before reaching the film.

After processing, the exposed areas of the film turn dark, representing the captured X-ray image, while the unexposed areas remain light or clear.

JL ≈ NM and K being the midpoint of JN and LM, we can prove that triangle JKL is approximately congruent to triangle NKM using the side-angle-side (SAS) congruence criterion.

To prove that triangle JKL is approximately congruent to triangle NKM based on the given information, we can use the congruence criterion of side-angle-side (SAS).

Given:

JL is approximately equal to NM

K is the midpoint of JN and LM

To prove:

JKL ≈ NKM

Proof:

Since K is the midpoint of JN and LM, we can conclude that JK is congruent to KM and KL is congruent to KN. This is because the midpoint of a line segment divides it into two congruent segments.

JL is approximately equal to NM, given in the problem.

We have JK ≈ KM (from step 1) and JL ≈ NM (given).

Now, we have two pairs of congruent sides: JK ≈ KM and JL ≈ NM.

Since we have two pairs of congruent sides and the included angles, angle JKL and angle NKM, share a common side KL ≈ KN, we can apply the side-angle-side (SAS) congruence criterion.

Therefore, by SAS congruence, we can conclude that triangle JKL is approximately congruent to triangle NKM.

Note: The use of the term "approximately congruent" suggests that the triangles are not exactly congruent but share enough similarity based on the given information.

In conclusion, based on the given information of JL ≈ NM and K being the midpoint of JN and LM, we can prove that triangle JKL is approximately congruent to triangle NKM using the side-angle-side (SAS) congruence criterion.

The answer is 16

Step-by-step explanation:

Answer: y = 3x - 6

Step-by-step explanation:

Using point-slope form:

y - y1 = m(x - x1)

where m is the slope, and (x1, y1) is the given point.

Substituting the values, we get:

y - 5 = (-1/4)(x - (-12))

Simplifying:

y - 5 = (-1/4)x - 3

y = (-1/4)x + 2 (slope-intercept form)

Using point-slope form:

y - y1 = m(x - x1)

where m is the slope, and (x1, y1) is the given point.

Substituting the values, we get:

y - (-6) = 3(x - 0)

Simplifying:

y + 6 = 3x

y = 3x - 6 (slope-intercept form)

Answer:

m<A is 60 degrees

m<B is 30 degrees

Step-by-step explanation:

As the problem says, the sum of m<A and m<B=90 degrees (m<A+m<B=90). The given measures are (5x+10) for <A and 3x for <B

we can substitute (5x+10) and 3x as <A and <B into the equation

so:

5x+10+3x=90

Combine like terms

8x+10=90

subtract 10 from both sides

8x=80

divide by 8

x=10

Now substitute as x

m<A: (5*10+10)=50+10=60 degrees

m<B: (3*10)=30 degrees

This means in one minute, which is 1/210 of the total time, they would have ran 1/210 of the total distance.

So the runner would have ran 26.2/210 miles per minute, which is 0.12476 miles.

Rounding to the nearest hundredth of a mile,

They ran 0.12 miles per minute, so the unit rate is 0.12 miles per minute.

B)

You can work out the minutes per mile using the same concept.

For one mile, the runner would have ran 1/26.2 of the total time, so they ran 210/26.2 minutes per mile, or 8.015 minutes per mile.

Rounding to the nearest tenth, you'd round down to 8.0 minutes per mile.

So they ran 8.0 minutes per mile.

2) C)

For C, the other runner talks about the same rate as b), not a). This is because they are referring to the time they took to run one mile, so the other runner ran 10 minutes to cover one mile, or as they say, "10 minute miles", which is the rate in minutes per mile.

If they were referring to the rates in a), that would imply the other runner ran 10 miles per minute... which is very unlikely.

Based on the sample of 50 students, 38 preferred Coke (50-12). To find the percentage of students who prefer Coke in the entire school, we can set up a proportion:

38/50 = x/1518

Solving for x, we get:

x = 1143.84

Rounded to the nearest whole number, we would expect 1144 students in the entire school to prefer Coke.

To answer your question, let's use the information given:

- 50 students were sampled
- 12 preferred Pepsi
- Therefore, 38 students (50-12) preferred Coke in the sample
- There are 1518 students in the entire school

Now, we can find the proportion of students who preferred Coke in the sample:

38 (Coke preferences) / 50 (total students in the sample) = 0.76

Now, to find the expected number of students who prefer Coke in the entire school:

0.76 (proportion of Coke preferences) * 1518 (total students in the school) = 1153.68

Rounding to the nearest whole number, we get:

Your answer: 1154 students are expected to prefer Coke in the entire school.

The analyst should use the alpha aesthetic. The alpha aesthetic makes some points on a plot more transparent than others to call out specific data points.

A set of points plotted on a horizontal and vertical axis is known as a scatter plot. Because they can demonstrate the degree of correlation, if any, between the values of observed quantities or phenomena, scatter plots are crucial in statistics (called variables). In an effort to demonstrate the degree to which one variable is influenced by another, scatter plots are used to plot data points on a horizontal and vertical axis. The values of the columns set on the X and Y axes determine the position of the marker that represents each row in the data table.

In statistical experiments, each time the experiment is repeated, a different outcome may occur. The correct answer is C.

Statistical experiments involve random processes, such as the random selection of individuals from a population, the random assignment of subjects to groups, or the random measurement of a variable.

The outcome of a statistical experiment is influenced by chance and is inherently uncertain, so it is not possible to guarantee that the same outcome will occur every time the experiment is repeated. Different outcomes may occur, even if the experimental conditions are kept constant, due to the random nature of the processes involved.
