The maximum distance that the sailοr can see frοm the deck οf the ship is 0 miles.

A special kind οf relatiοn knοwn as a functiοn is οne in which each input has precisely οne οutput. In οther wοrds, the functiοn generates exactly οne value fοr each input value. Because οne is mapped tο twο different values, the abοve graph depicts a relatiοnship rather than a functiοn. Hοwever, if οne were instead mapped tο a single value, the relatiοnship mentiοned abοve wοuld becοme a functiοn.

Additiοnally, οutput values can be equal tο input values. We knοw that the square rοοt functiοn is an increasing functiοn, which means that the value οf the functiοn increases as the input value increases.

Therefοre, tο find the maximum value οf the functiοn, we need tο find the maximum value οf h.

Assuming that the lighthοuse is οn the hοrizοn, which is apprοximately 3 miles away, we can use the Pythagοrean theοrem tο find the height οf the lighthοuse:

\(h^2 = (3)^2 - (15)^2h^2 = 9 - 225h^2 = -216\)

Since we cannοt take the square rοοt οf a negative number, there is nο real height fοr the lighthοuse that wοuld make it visible frοm a ship 15 feet abοve the water level.

Therefοre, the maximum distance that the sailοr can see frοm the deck οf the ship is 0 miles.

Answer:

3/8 + 1/4 is 5/8 and 1/10+4/5 is 1

Step-by-step explanation:

convert 1/4 to 2/8 and add to 3/8 to get 5/8

convert 4/5 to 9/10 and add to 1/10 equals 10/10 which is also 1

Answer:

9/10 (and 5/8 for question in title)

Step-by-step explanation:

To add fractions, you need to make a common denominator, which you can have a common denominator of 10.

To do this, multiply the numerator (4) and the denominator (5) by 2. You will get 8/10.

Now you can add them together: 8/10 + 1/10 = 9/10

I don't know if you wanted the question in the title answered too so here:

Same thing; common denominator. Use 8. Multiply 1 by 2 and 4 by 2. You get 2/8.

Add: 3/8 + 2/8 = 5/8

An inequality to represent the cost of Jason’s food for the party is

An inequality to represent this situation "Jason knows that he will be buying at least 5 packages of hot dogs" is

The two options for buying wings and hot dogs include the following:

In order to write a system of linear inequalities to describe this situation, we would assign variables to the number of packages of hot dogs and number of packages of wings respectively, and then translate the word problem into algebraic equation as follows:

Since one package of wings costs $7 and Hot dogs cost $5 per package, and he must spend no more than $40, a linear inequality which represents this situation is given by;

7x + 5y ≤ 40

Additionally, since Jason knew he would buy at least 5 packages of hot dogs, a linear inequality which represents this situation is given by;

y ≥ 5

Their exam must have been scheduled on Wednesday, allowing them to start hiking on Thursday after the exams.

To determine the day of the week on which Kai and Finley's exam was scheduled, we need to consider the information provided about the trail being closed on Mondays, Wednesdays, and weekends.

If they had planned to hike to the log cabin for two days after the exams, and the trail is closed on weekends, it means they cannot start hiking on Saturday or Sunday.

Since they cannot start hiking on Saturday or Sunday, the two possible options for the exam day would be Monday or Wednesday, as they have not specified whether the hike starts immediately after the exams or the day after.

However, we can conclude that their exam was not scheduled on Monday, as the trail is closed on Mondays, and they had planned to hike immediately after the exams.

Therefore, their exam must have been scheduled on Wednesday, allowing them to start hiking on Thursday after the exams.

Explanation:

When we add matrices, we must first make sure they are the same dimensions. In this case, both are 2x3 matrices, so we can add them.

To add matrices, you add the corresponding components.

For example, in the first row, first column, we have B+A = -2+4 = 2. So the value 2 will go in the first row, first column, of the answer matrix.

Answer:

16 males and 9 females.

Step-by-step explanation:

If you subtract 7 from 25 you get 18. If you split 18 in half you get 9. Which means if you add 7 to 9 you get the number of males, which leaves you with 9 students left so the rest are females.

Answer:

16 males and 9 females

Step-by-step explanation:

To solve this we can use a system of equations.

Let's start by naming the number of females x.

The number of males would then be y.

Using these variables, we can set up 2 equations using info provided:

A french class has a total of 25 students, -> x+y=25

The number of males is 7 more than the number of females -> x+7=y

Use substitution to solve.

From the second equation:

x+7=y

Subtract 7 from both sides.

x=y-7

Substitute that into the first equation.

x+y=25

y-7+y=25

Combine like terms.

2y-7=25

Add 7 to both sides.

2y=32

Divide both sides by 2.

y=16

Substitute y=16 into equation 2.

x+7=y

x+7=16

Subtract 7 from both sides.

x=9

Therefore, there are 16 males and 9 females in the french class.

Answer:

Here both line are perpendicular because as product of slope of both lines is -1

Answer:

lines are perpendicular

Step-by-step explanation:

If 2 lines are perpendicular then the product of their slopes = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

(1)

y = \(\frac{3}{4}\) x - 1 ← is in slope- intercept form

with slope m = \(\frac{3}{4}\)

(2)

3y = - 4x + 6 ( divide each term by 3 )

y = - \(\frac{4}{3}\) x + 2 ← in slope- intercept form

with slope m = - \(\frac{4}{3}\)

Then

\(\frac{3}{4}\) × - \(\frac{4}{3}\) = - 1

Thus the 2 lines are perpendicular to each other

Answer:

(1) 4.09% of the New York City commutes are for less than 26 minutes.

(2) 14.32% are between 26 and 32 minutes.

(3) 54.23% are between 26 and 40 minutes.

Step-by-step explanation:

We are given that the longest one-way travel time is in New York City, where the mean time is 38.5 minutes.

Assume the distribution of travel times in New York City follows the normal probability distribution and the standard deviation is 7.2 minutes.

Let X = travel times in New York City.

So, X ~ Normal(\(\mu=38.5,\sigma^{2} =7.2^{2}\))

The z-score probability distribution for the normal distribution is given by;

                           Z  =  \(\frac{X-\mu}{\sigma}\)  ~ N(0,1)

where, \(\mu\) = population mean travel time = 38.5 minutes

           \(\sigma\) = standard deviation = 7.2 minutes

(1) The percent of the New York City commutes that are less than 26 minutes is given by = P(X < 26 minutes)

    P(X < 26 minutes) = P( \(\frac{X-\mu}{\sigma}\) < \(\frac{26-38.5}{7.2}\) ) = P(Z < -1.74) = 1 - P(Z \(\leq\) 1.74)

                                                                 = 1 - 0.9591 = 0.0409 = 4.09%

The above probability is calculated by looking at the value of x = 1.74 in the z table which has an area of 0.9591.

(2) The percent of the New York City commutes that are between 26 and 32 minutes is given by = P(26 min < X < 32 min) = P(X < 32 min) - P(X \(\leq\) 26 min)

    P(X < 32 min) = P( \(\frac{X-\mu}{\sigma}\) < \(\frac{32-38.5}{7.2}\) ) = P(Z < -0.90) = 1 - P(Z \(\leq\) 0.90)

                                                          = 1 - 0.8159 = 0.1841

    P(X \(\leq\) 26 min) = P( \(\frac{X-\mu}{\sigma}\) \(\leq\) \(\frac{26-38.5}{7.2}\) ) = P(Z \(\leq\) -1.74) = 1 - P(Z < 1.74)

                                                           = 1 - 0.9591 = 0.0409

The above probability is calculated by looking at the value of x = 0.90 and x = 1.74 in the z table which has an area of 0.8159 and 0.881 respectively.

Therefore, P(26 min < X < 32 min) = 0.1841 - 0.0409 = 0.1432 or 14.32%.

(3) The percent of the New York City commutes that are between 26 and 40 minutes is given by = P(26 min < X < 40 min) = P(X < 40 min) - P(X \(\leq\) 26 min)

    P(X < 40 min) = P( \(\frac{X-\mu}{\sigma}\) < \(\frac{40-38.5}{7.2}\) ) = P(Z < 0.21) = 0.5832

    P(X \(\leq\) 26 min) = P( \(\frac{X-\mu}{\sigma}\) \(\leq\) \(\frac{26-38.5}{7.2}\) ) = P(Z \(\leq\) -1.74) = 1 - P(Z < 1.74)

                                                           = 1 - 0.9591 = 0.0409

The above probability is calculated by looking at the value of x = 0.21 and x = 1.74 in the z table which has an area of 0.5832 and 0.881 respectively.

Therefore, P(26 min < X < 40 min) = 0.5832 - 0.0409 = 0.5423 or 54.23%

To find the slope in this problem, we can use the formula for calculating slope, which is change in distance divided by change in time. In this case, the change in distance is 350 miles - 200 miles = 150 miles, and the change in time is 4:00 pm - 1:00 pm = 3 hours.

So, the slope (rate of driving) is 150 miles / 3 hours = 50 miles per hour.

Therefore, Sue will drive an additional 50 miles by 5:00 pm, making her total distance driven by 5:00 pm 200 miles + 150 miles + 50 miles = 400 miles. So, Sue will drive 400 miles by 5:00 pm if she continues at the same rate. Note that in this problem, we are assuming that Sue maintains a constant speed throughout her drive. If her speed changes, the solution may be different.

186 cm³ will be the surface area of the given figure.

To calculate the surface area of the given figure, we need to add the surface area of two cubes and reduce the area of the hidden part.

Thus,

Total surface area = Surface area of bigger cube + surface area of the smaller cube - 2* surface area of the hidden part.

So,

Total surface area = 6*(5*5)+6*(3*3)-2*(3*3)

Total surface area = 150+54-18

Total surface area = 186

Therefore, the surface area of the given figure will be 186 cm³.

Given the information, the probability that a response is between the ages of 18 and 29 and 30 or older is, respectively, 0.536 and 0.654. There is a 0.265 percent chance that they will say yes—that global warming will affect them over their lifetime. Concern over global warming also seems to vary across people aged 18 to 29 and those over 30.

Probability is the ratio of favourable events to all other potential outcomes in a circumstance. The symbol x can be used to denote how many successful outcomes there were in an experiment with 'n' outcomes. The formula below can be used to determine a given event's probability.

Positive Results/Total Results = x/n = Probability (Event)

The likelihood that a respondent between the ages of 18 and 29 believes that there will be no significant threat from global warming in his or her lifetime is:

P (18-29 and no) = 293/(134 + 293 + 117) = 0.536

The likelihood that a respondent who is 30 years of age or older believes that there will be no significant threat from global warming in his or her lifetime is:

P (30+ and no) = 432/(131 + 432 + 178) = 0.654

The likelihood that a randomly chosen respondent will select "yes"—that is, that they will experience the effects of global warming throughout their lifetimes—is:

P(Yes) = (134 + 131)/(134 + 131 + 293 + 432 + 117 + 178) = 0.265

Yeah, it does seem that younger people (18–29) are less concerned about global warming than older people (30+). In comparison to respondents aged 18 to 29, the likelihood that a respondent aged 30 or older believes that global warming will not constitute a severe hazard during their lifetime is higher (0.654). (0.536). According to this, respondents who are older are less concerned about global warming than respondents who are younger. To confirm this difference, a formal statistical test would be required.
