what is 6 plues 9 i need it plesae.

Answer:

for the first line let (-4,-3) be (x1,y1) and (8,0) be x2,y2.

now,

slope (m1) = (y2-y1)/ (x2-x1)

or, m1= 0-(-3)/ 8-(-4)

or, m1=3/12=1/4

again, for line two consider (0,2) as x1,y1 and (-1,6) be (x2,y2)

apply the same formula and find the slope(m2)

m2=6-2/-1-0

or, m2=4/-1

for b) m1 multiply m2

or 1/4 x 4/-1

=-1 so it is perpendicular

Step-by-step explanation:

for a we simply apply the formula of slope considering the given points as x1,y1 and x2,y2 respectively.

while for the b number if m1 x m2 =-1 the line is considered to be perpendicular.

similarly, if m1=m2 then it is considered to be parallel.

here m1 is slope of the first line, m2 is slope of second line and m3 is the slope of the third line

Answer: The number of seconds it will take is 143.25 seconds.The formula is s=g/1.075

Step-by-step explanation:

Given that the rate of gas release is 0.25 liter every second.This means;

1 second= 0.25 liter released

Also;

4.3 grams of gas equals 1 liter

This means;

4.3 grams = 1 liter

So for 154 grams, find the number of liters

=154/4.3= 35.81 liters

But you know;

0.25 liters = 1 second

35.81 liters=?

Cross multiply

(35.81*1)/0.25 =143.25 seconds

Let g be the grams of the gas, and l be the liters of the gas, then to get l you divide g by 4.3. This given you the formula;

l=g/4.3

Let s be the seconds it take for a gas device to release l liters of gas, so to get s you divide l by 0.25. This will be;

s=l/0.25 = (g/4.3) / 0.25

This simplifies to;

s= g/(4.3*0.25)

s=g/1.075

Answer:

Step-by-step explanation:

The probability that the residents do not own 2 cars if the annual household income is not over $50,600 is 20%.

To solve this problem, let's break down the given information and use conditional probability.

Let A be the event that the annual household income is over $50,000.

Let B be the event that the residents own 2 cars.

We are given the following probabilities:

P(A) = 0.60 (60% had incomes over $50,000)

P(B) = 0.70 (70% had 2 cars)

P(B|A) = 0.80 (the probability that residents own 2 cars if the annual household income is over $50,000)

We need to find the probability that the residents do not own 2 cars if the annual household income is not over $50,600. In other words, we need to find P(~B|~A), where ~A represents "not A" and ~B represents "not B."

Using the law of total probability, we can express P(~B|~A) as:

P(~B|~A) = P(~B ∩ ~A) / P(~A)

We know that P(~A) = 1 - P(A) = 1 - 0.60 = 0.40 (since ~A represents "not A").

Now, we need to find P(~B ∩ ~A), the probability of both not owning 2 cars and having an annual household income not over $50,600.

Since we don't have the direct probability of P(~B ∩ ~A), we can use the formula for conditional probability:

P(~B ∩ ~A) = P(~B|~A) * P(~A)

We are given P(B|A) = 0.80, so P(~B|~A) = 1 - P(B|A) = 1 - 0.80 = 0.20 (since ~B represents "not B").

Now we can substitute these values into the equation:

P(~B ∩ ~A) = P(~B|~A) * P(~A) = 0.20 * 0.40 = 0.08

Therefore, P(~B|~A) = P(~B ∩ ~A) / P(~A) = 0.08 / 0.40 = 0.20, which means the probability that the residents do not own 2 cars if the annual household income is not over $50,600 is 20%.

If an airplane flies a total distance of 450km in 3/4 hours, the plane is traveling at an average speed of 600 kilometers per hour.

The average speed refers to the quotient of the total distance divided by the total time used by the airplane to cover the distance.

Based on the distance, time, and speed equation, we can state that there exists an equation relationship, which is given as distance = time x speed.

The total distance flown by airplane = 450 kilometers

The total time used by the airplane to travel the distance = ³/₄ hours or 0.75 hours

Thus, the average speed of the airplane is 600 kilometers per hour (450 ÷³/₄).

The earliest start time for activity w can be determined by taking the maximum of the earliest finish times of its immediate predecessors, which are activities g, p, and r. In this case, the maximum is 15. Therefore, the correct answer is c. is 15.

Answer:

Step-by-step explanation:

We may not be able to fit 16 cases in the box because their combined volume will be greater than the box which will make it impossible.

The dimensions of the big box is given as:

Length= 26 cm

Breadth= 15 cm

Height= 20 cm

So its volume can be calculated by:

Volume= Length x Breadth x Height

Volume= 26 cm x 15 cm x 20 cm

Volume1= 7800 cm³

Now, the dimension of one disc case is given as:

Length= 1.6 cm

Breadth= 14.2 cm

Height= 19.3 cm

The volume of one disc case will be:

Volume= 1.6 cm x 14.2 cm x 19.3 cm

Volume= 438.496 cm³

So, volume of 16 disc cases= 16 X volume of one disc case

Volume2= 16 x 438.496 cm³

Volume2= 7015.936 cm³

Since Volume1 < Volume2

So, 16 disc cases cannot be fit into a box.

Answer:

18 inches cubed

Step-by-step explanation:

to get the volume for something you must multiply it. length × width × hight

so in this case it would be 3×2×3=18 inches cubed

In each scenario, the choice between mean and median as a representative measure of central tendency depends on the nature of the data and the specific context..

1. Scenario: Income distribution of a population

- If the income distribution is skewed or contains extreme values (outliers), the median would be a better representation of the central tendency. This is because the median is not influenced by outliers and provides a more robust estimate of the "typical" income level. However, if the income distribution is approximately symmetric without outliers, the mean can also be an appropriate measure.

2. Scenario: Exam scores in a class

- If the exam scores are normally distributed without significant outliers, the mean would be a suitable measure as it takes into account the value of each score. However, if there are extreme scores that deviate from the majority of the data, the median may be a better representation. This is especially true if the outliers are indicative of errors or exceptional circumstances.

3. Scenario: Housing prices in a city

- In this case, the median would be a more appropriate measure to represent the central tendency of housing prices. This is because the housing market often exhibits a skewed distribution with a few high-priced properties (outliers). The median, being the middle value when the data is sorted, is not influenced by these extreme values and provides a better understanding of the typical housing price in the city.

Ultimately, the choice between mean and median depends on the specific characteristics of the data and the objective of the analysis. It is important to consider the distribution, presence of outliers, and the context in which the data is being interpreted.

Answer:

15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\(\mu = 26, \sigma = 3\)

Approximately what percentage of her shots will travel less than 23 feet?

This is the pvalue of Z when X = 23. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{23 - 26}{3}\)

\(Z = -1\)

\(Z = -1\) has a pvalue of 0.1587.

15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.

The most appropriate measure of spread for this data is standard deviation, because the boxplot is skewed to the right.

The most appropriate measure of spread for this data is standard deviation. The data is represented by a boxplot, which is a graphical representation of the data that shows the median, quartiles, and range of the data. In this case, the boxplot is skewed to the right, meaning that the data is not normally distributed. When the data is not normally distributed, the standard deviation is the best measure of spread to use. Standard deviation measures the spread of data by calculating the distance between each data point and the mean, and then taking the average of these distances. This allows us to accurately measure the spread of data that is not normally distributed. Therefore, standard deviation is the most appropriate measure of spread for this data.
