Answer:

10 and 5.

Step-by-step explanation:

Let the integers be x and y.

xy = 50

x = 2y

Put x as 2y in the first equation.

(2y)y = 50

2y² = 50

y² = 50/2

y² = 25

y = √25

y = 5

Put y as 5 in the second equation.

x = 2(5)

x = 10

Of mountain climbers who attempt Mt. McKinley, only 65% reach the summit. In a random sample of 16 climbers who will make the attempt, what is the probability of each of the following?



a.) Exactly 14 of 16 reach the summit.

b.) At least 14 reach the summit.

C.) No more than 5 reach the summit.

d.) Between 9 and 12 reach the summit (including 9 and 12)

e.) What is the mean and standard deviation of this study?

f.) If 73% of climbers reached the summit, what is the probability that exactly 14 of 16 climbers make it now?​

Part a)

Divide 14 by 16

so

P=14/16

P=7/8

Multiply by 0.65

Answer:

n = 10.286      aprox.

Step-by-step explanation:

n+4 + n/6 = 16

n/6 = 16 - 4 - n

n = 6(12-n)

n = 6*12 + 6*-n

n = 72 - 6n

n + 6n = 72

7n = 72

n = 72/7

n = 10.286       aprox.

verify:

10.286 + 4 + (10.286/6) = 16

14.286 + 1.714 = 16

Answer:

\(y_1 = \left[\begin{array}{ccc}1\\-4\\0\\1\end{array}\right]\)  ,  \(y_2 = \left[\begin{array}{ccc}5\\1\\-6\\-1\end{array}\right]\)

Step-by-step explanation:

\(x_1 = \left[\begin{array}{ccc}1\\-4\\0\\1\end{array}\right]\)    and \(x_2 = \left[\begin{array}{ccc}7\\-7\\-6\\1\end{array}\right]\)

Using Gram-Schmidt process to produce an orthogonal basis for W

\(y_1 = x_1 = \left[\begin{array}{ccc}1\\-4\\0\\1\end{array}\right]\)

Now we know X₁ , X₂ and Y₁

Lets solve for Y₂

\(y_2 = x_2- \frac{x_2*y_1}{y_1*y_1}y_1\)

Step-by-step explanation:

To get the y values all you need to do is substitute the x value in the equation y=-2/3x+7.

For example:

y=-2/3(-6)=7

-2/3x6=-4

-4+7=3

(-6,3)

You can double check your work by filling the x and y coordinates in the equation and when solved if it it true you know you were correct.

To get the x value, you need to fill in the y in the equation y=-2/3x+7

for example:

5=-2/3x+7

-2=-2/3x

3=x

(3,5)

y=-2/3x+7

y=-2/3(15)+7

y=-10+7

Answer:

x = 2 or x = -5

Step-by-step explanation:

x² + 3x - 4 = 6

x² + 3x -4 - 6 = 0

x² + 3x - 10 = 0 (Here you find two numbers that have a sum of 3 and a product of -10. These two numbers would be 5 and -2. 5 - 2=3 and 5×-2 =-10.)

x² + 5x - 2x -10 = 0 (They you replace 3x by 5x and -2x)

(x² + 5x) (-2x -10) =0 - (You find common terms)

x(x + 5) -2(x + 5) = 0

(x - 2) (x + 5) = 0

So

x - 2 = 0 or x + 5 = 0

x =2               x = -5

Answer:x=2

Step-by-step explanation:

x^2+3x-4=6

2x+3x-4=6

add 2x and 3x and you get 5x

5x-4=6

add 4 to both sides 6 plus 4 is 10

5x=10

know divide 5 from both sides and you get 2

Answer:

(x - 5)² + (y + 6)² = 16

Step-by-step explanation:

assuming you require the equation of the circle

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (5, - 6 ) and r = 4 , then

(x - 5)² + (y - (- 6) )² = 4² , that is

(x - 5)² + (y + 6)² = 16

An open circle at 5 and a bold line starting at 5 and pointing to the right (>) is the correct representations of the inequality

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value e.g 5 < 6, x ≥ 2, etc.

Given: the inequality –3(2x – 5) < 5(2 – x)

First, we have to solve for x in the inequality

–3(2x – 5) < 5(2 – x)

Clear the parenthesis:

-6x + 15 < 10 - 5x

Collect like terms:

-6x + 5x < 10 - 15

-x < -5

Divide both sides by -1:

x > 5              ( Note:  Dividing both sides by -1 will change the < to > )

This is what will determine our answer

Since our answer is x > 5.  An open circle will be at 5 and a bold line starts at 5 and is pointing to the right (>)

Therefore,  the correct representations of the inequality is  an open circle is at 5 and a bold line starts at 5 and is pointing to the right

73 is the rate of the eastbound train while The speed of the westbound train is 59 miles per hour.

speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.

Given, Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 miles per hour slower than the westbound train.

Eastbound train:

time = 3 hrs, rate = x mph, distance = 3x miles

Westbound train:

time = 3 hrs ; rate = x-14 ; distance = 3x-42 miles

3x + 3x - 42 = 480

6x = 438

x = 73 (rate of the eastbound train)

To find the rate of the westbound train:

rate = x -14

rate = 73 - 14

rate of westbound train = 59

Therefore, The speed of the westbound train is 59 miles per hour.

Therefore , the solution of the given problem of arithmetic mean comes out to be -12 and 7 have an algebraic mean of -2.5.

The typical values of a list, which are sometimes referred to because the objectives of an organization, are obtained by adding up each and every item on the list. These average values are then modified using the number of items in the list with the greatest abundance. Growth patterns in mathematics are comparable. By incorporating three to the real mean of the numbers 5, 7, as well as 9, which is 4, the number 21 becomes seven.

Here,

Two numbers are added together and their total is divided by two to determine the arithmetic mean of the numbers.

The arithmetic mean of the integers -12 and 7 is

=>  {-12 + 7}/ {2}

=>  {-5}/{2}

=>  -2.5

As a result, -12 and 7 have an algebraic mean of -2.5.

y = -2x² - 8x + 3

════════════════════

#First, find the x coordinate first by using the formula of -b/2a

x = -b/2a = -(-8)/2(-2) = 8/-4 = -2

#After getting the x, find the y

y = -2(-2)² - 8(-2) + 3

y = -2×4 +16 + 3

y = -8 + 16 + 3

y = 11

So the vertex is

(-2,11)

════════════════════

Answer:

the vertex is (-2, 11)

Step-by-step explanation:

F(x) = -2X^2 - 8X + 3 can be rewritten as -2(x^2 + 4x) + 3.

We complete the square of x^2 + 4x, obtaining x^2 + 4x + 4 - 4 = (x + 2)^2 - 4

and then we substitute this last result into F(x) = -2(x^2 + 4x) + 3:

F(x) = -2[ (x + 2)^2 - 4 ] + 3, which simplifies to:

F(x) = -2(x + 2)^2 + 8 + 3, or F(x) = -2(x + 2)^2 + 11

Comparing this to the vertex equation (x + h)^2 + k, we see that h must be -2 and k must be 11.  

Thus, the vertex is (-2, 11).

A scale factor of 7 is it an enlargement neither.

Scale factor is a ratio of two corresponding lengths, areas, or volumes of similar shapes. When two shapes are similar, one can be enlarged or reduced to create the other. The scale factor is the number by which a figure is multiplied or divided to form a similar figure. It is used in many areas of mathematics, including geometry, trigonometry, and algebra. It is also used in engineering and architecture to create drawings of scaled-down or scaled-up objects.

A scale factor of 7 does not necessarily indicate an enlargement or reduction; it simply states that the size of an object has been multiplied by a factor of 7. It could either increase or decrease the size of the object, depending on the original size of the object and the direction of the scale factor.
