(q027) a recent study by pew (purcell 2011) found gendered differences in applications (apps) downloaded by men and women. men are more likely to download and use , whereas women tend to use more than men.

Answers

Men are more likely to download and use , but women use both sides of the brain while men only use the left for visual or spatial expression. So, There is a relationship between gender and intended major.

Based on the given conditions,

Differences in applications (apps) downloaded by men and women.

Men are more likely to download and use , whereas women tend to use more than men.

So,

We can write,

According to studies comparing the brain activity of men and women,

When performing language-related tasks, women's brains are more likely than men's to be engaged in the right hemisphere.Men express their emotions using the right side of the brain, whereas women use both sides.Women use both sides of the brain while men only use the left for visual or spatial expression.Although men tend to be more emotional than women, women often express and display their feelings the most, giving the impression that they are more emotionally sensitive than men.From the above question, we can see that most women in research positions want to use, while most men want to study download and use. From this we can conclude that there is a greater correlation between female gender and use (according to this study) than male gender and download and use . Therefore, the results of this study indicate that there is a relationship between gender and primary intentions.

Therefore,

Men are more likely to download and use , but women use both sides of the brain while men only use the left for visual or spatial expression. So, There is a relationship between gender and intended major.

The equation that represents the linear relationship between each x- and y-coordinate is: y = x - 2.

How to Create an Equation for a Relationship?

For a linear relationship between x and y coordinate, an equation in slope-intercept form that can be created is expressed as y = mx + b.

"m" is the slope = change in y / change in x."b" is the y-intercept.

Find the slope (m) using any two pairs of values, (1, 0) and (3, 2):

Slope (m) = (2 - 0)/(3 - 1)

Slope (m) = 2/2

Slope (m) = 1

Find the y-intercept by substituting m = 1 and (x, y) = (1, 0) into y = mx + b:

0 = 1(1) + b

0 = 2 + b

-2 = b

b = -2

Write the equation of the relation by substituting m = 1 and b = -2 into y = mx + b:

y = x - 2

The relationship Mandy made with coordinate points is y = x - 1.

What is the x-y coordinate?

an x-y coordinate is a 2D plane in which we can plot points of x and y together to make a coordinate. We can graph lines or any 2D figure using x-y coordinates.

We determine the relationship between x and y we'll go with the

hit-and-trial method.

At x = 1, y = 0.

At x = 11 , y = 10.

We can observe that y is one less than x, this can be represented as,

y = x - 1.

To cross-check out the equation can put given values of x and y and check whether it satisfies our equation or not.

The cost of petrol rises by 2 cents a liter. last week dora the explorer bought 20 liters at the old price. This week she bought 10 liters at the new price. Altogether, the petrol costs $9.20. What was the old price for 1 liter?

Answers

The old price at which dora bought 20 liters of petrol is $0.30 per liter.

Given, dora bought 20 liters of petrol at old price.

The cost of petrol rises by 2 cents later.

Then she bought 10 liters at the new price.

Altogether the petrol costs = $9.20

old price for 1 liter = ?

let the old price for 1 liter of petrol be x.

Based on the conditions , we formulate:

20x+10(x+2)=920

20x+10x+20=920

30x+20=920

30x=920-20

30x=900

x=900/30

x=30

x=$0.30

hence the old price of the petrol is $0.30 per liter.

<1 is a complement of <2, and m<1=23. find m<2

Answers

The value of the angle m∠2 = 67°.

Angle may be defined as the space between two lines. An angle consists of a vertex with which the angle is extended. When sum of two angles is exactly 90°, they are called complementary angles. For example, if we have two angles a and b then, ∠a + ∠b = 90°. When sum of two angles is exactly 180°, they are called supplementary angles. For example, if we have two angles a and b then, ∠a +∠b =180°. According to the given question ∠1 is a complement of ∠2 and we know when two angles are complementary to each other sum of their angles is 90°. So,

m∠1 + m∠2 = 90°

Now, m∠1 = 23°

23° + m∠2 = 90°

m∠2 = 90° - 23°

m∠2 = 67° which is required angle.

What is Trigonometry?The area of mathematics known as trigonometry studies how triangles' sides and angles relate to one another as well as how various angles might be used in useful ways. For determining the positions of the sun, moon, and stars, forecasting eclipses, and defining planet orbits, spherical trigonometry has been utilized for ages. To determine the distance to neighboring stars in the modern era, astronomers utilize the triangulation method. Satellite navigation systems also employ this method.By combining the laws of sines and cosines with these functions, it is possible to practically any queries concerning arbitrary triangles. When a triangle has two sides and an included angle or two angles and a side, these principles can be applied to determine the remaining angles and sides.As soon as two sides, their included angle, two angles, a side, or three sides are known, these principles can be used to calculate the remaining angles and sides of any triangle.

Find the number that should be added to the equations to make it a complete squares.

1. x^2 + 22x
2. x^2 - 2x
3. x^2 + 7x

Answers

The number that must be added to complete the squares is 121 .

Since x² represents the area of a square with a side of length x and bˣ represents the area of a rectangle with sides b and x, the process of completing the square can be seen as a visual manipulation of rectangles.

When the x² and bˣ rectangles are simply joined into a larger square, a corner is lost. The expression (b/2)² can be added to each side of the equation above to calculate the area of the remaining corner, thereby giving rise to the idiom "completing the square".

the given expressions are x² + 22x

This can be written in the form of a square polynomial as :

x² + 2×x×11 + 11² = (x+11)²

Therefore we have to add 11² = 121 to the polynomial to complete the square.

Similarly for  x² - 2x we have to add 1 to get the form (x-1)²

And we have to add x²+ 7x + (7/2)²

Hence the number to be added is 49/4 .

Two airplanes are flying in the air at the same height. Airplane A is flying east at 200 mph and airplane B is flying north at 250 mph. If they are both heading to the same airport, located 30 miles east of airplane A and 40 miles north of airplane B, at what rate (in mph) is the distance between the airplanes changing?

Answers

The rate at which the distance between the airplanes is changing is;

dC/dt = 320 mi/h

We are given;

The Speed of Airplane A; dA/dt = 200 mi/h

The Speed of Airplane B; dB/dt = 250 mi/h

Aircraft A and B will form a right-angled triangle because Aircraft A is flying east and Aircraft B is flying north, and we can use Pythagoras' theorem to calculate their distance from one another.

Let C be the distance.

Therefore;

C² = A² + B²

Differentiating the above equation with respect to t,

2C(dC/dt) = 2A(dA/dt) + 2B(dB/dt)

Dividing each side of the equation by 2,

C( dC/dt ) = A( dA/dt ) + B( dB/dt )

Where dC/dt is the rate of change in distance between the two aircraft.

Now,

C² = A² + B²

C = √(A² + B²)

Substituting, A = 30 miles and B = 40 miles;

C = √(30² + 40²)

C = √( 900 + 1600 )

C = √2500

C = 50 miles

Substituting the value in the equation C( dC/dt ) = A( dA/dt ) + B( dB/dt ),

50(dC/dt) = (30 × 200) + (40 × 250)

50(dC/dt) = 6000 + 10000

50 × dC/dt = 16000

dC/dt = 16000/50

dC/dt = 320 mi/h

The sum of the first 26 terms for an arithmetic sequence is 1417.
The sum of the first 8 terms for the same arithmetic sequence is 76.
Find the value of the first term.

Answers

The value of the first term is - 8.

Given that:-

Sum of the first 26 terms for an arithmetic sequence = 1417.

Sum of the first 8 terms for the same arithmetic sequence = 76.

We have to find the value of the first term.

We know that,

Sum of first n terms of an AP is given by:-

S(n) = (n/2)(2a + (n - 1)d)

Where,

n is the number of terms,

a is the first term and,

d is the common difference.

Hence,

S(26) = 1417 =  (26/2)(2a + (26 - 1)d) = 13(2a + 25d) = 26a + 325d

S(8) = 76 = (8/2)(2a + (8 - 1)d) = 4(2a + 7d) = 8a + 28d

Here we have two equations:-

26a + 325d = 1417  ...(1)

8a + 28d = 76  ....(2)

Multiplying (1) by 4 and (2) by 13 , we get

104a + 1300d = 5668

104a + 364d = 988

Subtracting and eliminating a , we get,

936d = 4680

d = 4680/936 = 5

Substituting d = 5 in (2), we get

8a + 28(5) = 76

8a + 140 = 76

8a = 76 - 140

8a = -64

a = -64/8 = -8

Hence, the first term is -8.
