Please answer this question,I will mark you the brainiest

The plane's altitude after 1 minute of flight when it leaves the runway with a speed of 275 feet per second and an angle of climb of 18 degrees is 5098.78 feet.

Therefore, the answer is 5098.78ft

Speed of airplane = 275ft/s

Angle of climb = 18°

Time travelled = 1min = 60s

Distance covered in 60s is given by multiplying speed with time taken, that is

distance = 275 × 60

= 16,500ft

But this distance obtained is not the altitude, it is the hypotenuse and we know sin∅ = altitude/ hypotenuse. That is

sin(18) = altitude/ 16500

altitude = 16500sin(18)

= 5098.78ft

Answer:

255

Step-by-step explanation:

10n^2+5

where n=5

10×5²+5

10×25+5

250+5

255

The 5th term of Sequence is 255.

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms). The length of the series is the number of elements (potentially infinite).

Given:

10n² +5

Now for 5th term put n= 5 we get

10n² +5

= 10(5)² +5

= 10 x 25 + 5

= 250+ 5

= 255

hence, the 5th term is 255.

Define quadratic equation?

A quadratic equation is a second-degree polynomial equation in one variable of the form a + b + c = 0, where a, b, and c are constants and x is the variable. The term "quadratic" comes from the Latin word "quadratus", which means square.

Given:

\(x^{4} - 8x^{2} y^{2} +16y^{4} -289\) equals to 0

\(x^{4} - 8x^{2} y^{2} +16y^{4} -289 = 0\)

\(x^{4} - 8x^{2} y^{2} +16y^{4} =289\)

We know that \((x-b)^{2} =x^{2} -2xy +y^{2}\)

Compare it: \((x^{2} -4y^{2} )^{2} = x^{4} - 8x^{2} y^{2} +16y^{4}\)

So, \((x^{2} -4y^{2} )^{2} = 289\)

\((x^{2} -4y^{2} ) = 17\)

We know that \((x^{2} -b^{2} ) = (x+y)(x-y)\)

So, \((x +2y)(x-2y) =17\)

If we solve two equations that is:

(x+2y) = 17 and  (x-2y) = 17

Simplification, x = 17 and y = 0

The random variable representing the grades of the students in the class is a continuous random variable. To find the probability that the grades fall precisely within 10 percentage points from the average, we need to calculate the area under the probability density function (PDF) within this range. To find the probability that student grades fall between 74% and 85%, we need to calculate the area under the PDF within this range.

The random variable representing the grades of the students in the class is a continuous random variable since it can take on any value within a certain range (0 to 100 in this case) and is not restricted to specific discrete values. To find the probability that the grades fall precisely within 10 percentage points from the average (65.5 ± 5), we need to calculate the area under the probability density function (PDF) within this range. This can be done by integrating the PDF over the specified range. To find the probability that student grades fall between 74% and 85%, we also need to calculate the area under the PDF within this range. Again, this can be done by integrating the PDF over the specified range. The result will give us the probability that a randomly selected student's grade falls within this range.

I will only give answer if you gave 100 points . will you give ?

Step-by-step explanation:

This is a word problem that we must translate to mathematical expression before we can solve.

let the individual saving be the first letters of the names

Jada= J

Lin= L

Elena= E

1. Jada saved $20 less than Lin

    J=L-20

2. Lin saved 3 times as much money as Elena

   L= 3E

3. Hence Elena saved

   E

Together they saved $120.

hence

(L-20)+3E+E= 120

L-20+3E+E= 120

collecting like terms we hav

L+4E=120+20

L+4E= 140

but we know that L= 3E

3E+4E= 140

7E= 140

divide both sides by 7 we have

E= 140/7

E= $20

This means Elena saves $70

also  L= 3E

L= 3*20

L= $60

this means that Lean saved $60

also  J=L-20

J= 60-20

J= $40

This means that Jada saved $40

The mean number of tomatoes for the Ultra Boy tomato plant is calculated by adding up all the quantities and dividing by the total number of plants, which is 10 in this case. So, the mean is (32+46+51+43+42+56+28+41+39+53)/10 = 43.1 tomatoes per plant.

To find the median number of tomatoes, we need to first arrange the quantities in numerical order: 28, 32, 39, 41, 42, 43, 46, 51, 53, 56. The median is the middle number in this list, which is 43.

The missing part of the equation is \(-7.0\times10^4 s^2kg⋅m^2 / 1000000.\)

To fill in the missing part of the equation, let's analyze the given information and the desired conversion. The equation is:

\((-7.0\times 10^4 s^2g⋅m^2)\cdot \pi = ? s^2kg\cdot m^2\)

In this equation, we have a quantity expressed in\(s^2g\cdot m^2\) units on the left-hand side. To convert it to \(s^2kg\cdot m^2\) units, we need to multiply it by a conversion factor.

To perform the conversion, we can use the fact that 1 kg is equal to 1000 g. Therefore, the conversion factor we need is:

1 kg / 1000 g

To ensure that the units cancel out correctly, we need to square this conversion factor because we have \(s^2g\cdot m^2\) on the left-hand side. So the missing part of the equation is:

\((-7.0\times 10^4 s^2g\cdot m^2)\cdot \pi = (-7.0\times 10^4 s^2g\cdot m^2)\cdot (1 kg / 1000 g)^2\)

Simplifying this expression, we get:

\((-7.0\times10^4 s^2g\cdot m^2)\cdot \pi = -7.0 \times10^4 s^2kg\cdot m^2 / 1000000\)

Therefore, the missing part of the equation is \(-7.0 \times 10^4 s^2kg\cdot m^2 / 1000000.\)

The five number summary is

===========================================================

Further Explanation:

The original data set is {24, 32, 25, 27, 37, 29, 30, 30, 28, 31, 27, 23}

It sorts to {23, 24, 25, 27, 27, 28, 29, 30, 30, 31, 32, 37} when going from smallest to largest.

There are n = 12 items in this set. The median is found between slots 6 and 7 because n/2 = 12/2 = 6

Circle the items in slot 6 and slot 7 to highlight 28 and 29 in that order. The midpoint is (28+29)/2 = 57/2 = 28.5 which is the median.

Median = 28.5

---------------

Now break the set up into two pieces

L = {23, 24, 25, 27, 27, 28}

U = {29, 30, 30, 31, 32, 37}

L is the lower set below the median, U is the upper set above the median

The midpoint of L is (25+27)/2 = 26 and the midpoint of set U is (30+31)/2 = 30.5

This gives us Q1 = 26 and Q3 = 30.5 respectively

Q1 = first quartile

Q3 = third quartile

The min and max are simply the smallest and largest items of the set

min = 23

max = 37

------------------

We have this five number summary:

These five items directly determine the positioning of the box and whiskers. No extra info is needed.

The min and max handle the tips of the left and right whiskers if we don't have any outliers. In this case, we don't have outliers so we can ignore this aspect.

The Q1 and Q3 handle the left and right edges of the box

The median (aka Q2) is the vertical line inside the box. It doesn't have to be at the center of the box. It's simply anywhere inside.

With all this in mind, the best match is choice D

----------------------------------

In other words, we can eliminate the following

Since A, B, and C are eliminated, the only thing left is choice D which matches all aspects of the five number summary above.

Yes, it is possible to find the covariance and correlation of x and y given a joint distribution table.

The covariance of x and y can be calculated using the formula:

cov(x,y) = E[(x - E[x])(y - E[y])]

where E[x] and E[y] are the expected values of x and y, respectively.

The correlation of x and y can be calculated using the formula:

cor(x,y) = cov(x,y) / (sd[x] * sd[y])

where sd[x] and sd[y] are the standard deviations of x and y, respectively.

Both the covariance and correlation are measures of the relationship between two variables, and can provide insight into the strength and direction of that relationship.

The interquartile range is 55.

The interquartile range is the difference between the upper quartile and the lower quartile. In example 1, the IQR = Q3 – Q1 = 87 - 52 = 35. The IQR is a very useful measurement. It is useful because it is less influenced by extreme values as it limits the range to the middle 50% of the values.

Interquartile range = higher quartile - lower quartile

Given data,    50,25,80,10

To arrange the given data in ascending order 10,25,50,80.

Now, we will find the median for the given data.

The median is obtained by first arranging the data in ascending order and applying the following rule.

If the number of observations is even, then the median is \(\frac{n}{2}th\) term.

In given data the number of observations is '4'(even)

If the number of observations is even, then the median is \(\frac{4}{2} th\) means 2nd term. So median for the given data is 25. It means the value of lower quartile is 25 .

Interquartile range = higher quartile - lower quartile

                                 = 80-25

                                = 55
