Answer:

Being male and preferring brand A are independent.

Because: if independent then P(male and brand A) = P(male) P(brand A) = 0.48 * 0.75 = 0.36 and that is true (= value in the table)  

P(male|brand A)=0.36/0.75=0.48 = P(male)

So the two answers are:

(1) "independent"

According to the directions, the location I am at is 65o N, 75o E.

To know our location we must take into account the information we have, which is:

According to the above, the easiest thing to know is the longitudinal location with respect to the Greenwich meridian, so if we are 5 hours ahead of the reference time we can establish that we are at 75° E.

On the other hand, taking the polar star as a reference, the latitudinal location can be established. Keep in mind that the polar star is only visible in the northern hemisphere, so we would be in this hemisphere.

On the other hand, the way to know how far north we are is by calculating the degrees between the horizon and the star, that will tell us what latitudinal location we are at. So if the star is at 65°, we may be close to 65° north latitude.

Answer:

After 1 second, the ball will reach a maximum height of 16 feet

Step-by-step explanation:

The height of the ball after t seconds: h(t) = -16t^2 + 32t

The graph of this quadratic function is parabola which opens downwards. The vertex of a quadratic equation is the maximum or minimum point on the equation's parabola

t = -b/2a = -(32)/2(-16) = -32/-32 = 1 second

then

h(t) = -16(1)^2 + 32(1) = -16 + 32 = 16

After 1 second, the ball will reach a maximum height of 16 feet

Answer: Y = 7x/2 -2

Step-by-step explanation:

Y intercept of -2 means there's a point at (0,-2).

Given the two points (4,12) and (0,-2), we can now find the slope

12-(-2)/4-0 = 14/4 = 7/2 which is the slope

so the equation is Y = 7x/2 -2

Answer:

(n - 3)(2)  or  2(n - 3)

Step-by-step explanation:

The area of a rectangle is its length multiplied by its width.  But which side is length is up to you; there are 2 choices!

If the side marked n - 3 is the length, then the side marked 2 is the width.  the area is (n - 3)(2).

On the other hand, if the side marked 2 is the length, then the side marked n - 3 is the width.  The area is 2(n - 3).

By the way, both those expressions are equivalent to 2n - 6.

Answer:

5.5 in

Step-by-step explanation:

first set up an equation. 24 is your total, so put it on one end of the equal side, and x+2 on the other (24=x+2) then you subtract 2 from BOTH SIDES so that u get x by itself

24=x+2

-2       -2

22=x

since it is a square divide 22 by 4

22/4= 5.5

so 5.5 in is your answer.

Answer:6 FOR EACH OF THE SIDE

Step-by-step explanation:

Ok we know that a square has 4 equal sides and we know the total perimeter is 24, all we need to do is multiply 4*2 which is 8, so 4x+8 and all we need to do is circle move and divide so 4x+8=24, 4x=16, x=4 and now we know that each side has a total value of 6 since substitute x with 4 and get 6.

Step-by-step explanation:

A transversal is a line that is intersecting at 2 points. Let's verify all options to see which one is the odd one out.

Option A

This line is a transversal to AC because it is intersecting in between AC. Hence, Option A is incorrect for this question.

Option B

This line is also a transversal to AC because it is intersecting in between AC. Hence, Option B is incorrect for this question.

Option C

This line is not a transversal because it is not intersecting AC. Hence, this will be the correct answer for this question.

Option D

This line is a transversal because it is intersecting in between AC. Hence, Option D is incorrect for this question.

After verifying all options, Option C is the most reasonable option. Hence, Option C is correct.

Buy 14 cupcakes

Step-by-step explanation:

4 - 9 - x

the pattern is plus 5

9+5=x

x=14

The required number of the cups next in the series is given as 14, the required series is given as 4, 9, 14, and so on.

Given that,
Two weeks ago, bought 4 cupcakes last week, and bought 9, a series to be determined.

A Series is defined as a group of numbers related or nonrelated to each other

Here,
According to the question,
2 weeks ago Number of cupcakes was 4,
1 week ago the number of cupcakes was 9.
The relationship formed can be given as y = --5x + 14,
put x = 0 we would get the number that comes next in the series,
So,
y = -5(0) + 14
y = 14

Thus, the required number of the cups next in the series is given as 14, the required series is given as 4, 9, 14, and so on.

Step-by-step explanation:

Linear equation are the equation which has the highest power of the unknown variable is 1.The expressions given in the  option 1, 2, and 3 are equivalent to [tex]7x - 14[/tex].

The equations given in the problem are the linear equations.

Linear equation are the equation which has the highest power of the unknown variable is 1.

Given-

1) The given expression in the problem is,

[tex]f(x)=7x-14[/tex]

Rewrite the equation as,

[tex]f(x)=(7x-14)[/tex]

Take out the negative sign from the bracket,

[tex]f(x)=-(-7x+14)[/tex]

Rewrite the equation with positive terms first.

[tex]f(x)=-(14-7x)[/tex]

Hence the given equation is equivalent to the option 1.

2) The given equation,

[tex]f(x)=7x-14[/tex]

On solving further take out the 7 common from the bracket,

[tex]f(x)=7(x-2)[/tex]

Thus the given equation is equivalent to the option 2.

3) The given equation,

[tex]f(x)=7x-14[/tex]

Split the term of x,

[tex]f(x)=4x+3x-14[/tex]

Rewrite the equation,

[tex]f(x)=3x-14+4x[/tex]

Hence the given equation is equivalent to the option 3.

4) The given equation,

[tex]f(x)=7x-14[/tex]

Split the term of x and constant term,

[tex]f(x)=5x+2x-10-4[/tex]

Rewrite the equation,

[tex]f(x)=2x-10+5x-4[/tex]

Hence the given equation is not equivalent to the option 4.

= (-0.25, 3)

Step-by-step explanation:

the height BD is (using Pythagoras) :

BD² = CB² - CD² = 9² - 3² = 81 - 9 = 72

BD = sqrt(72)

the height to the Hypotenuse of a right-angled triangle is also the square root of the product of the segment lengths of the Hypotenuse (the segments created by point D).

so, BD = sqrt(3×(x-3))

therefore,

sqrt(72) = sqrt(3×(x-3))

72 = 3×(x-3) = 3x - 9

81 = 3x

x = 27

The given distances and time give the speed of each elevator. The

distances traveled in 12 and 35 seconds can be found from the speed.

Correct responses:

The possible given data based on a similar question posted online is presented as follows;

[tex]\begin{tabular}{|l|c|c|c|} \underline{Building} & \underline{Approximate Distance (feet)}& \underline{Time (seconds)}& \underline{Speed (ft./s)}\\Empire State Building&233&10&23.3\\John Hancock Center&150&5&30\\One World Trade Center&666&20&33.3\\Space Needle&368&25&14.72\\Willis Tower&401&15&26.7\overline{3}\end{array}\right] [/tex]

The speed of each elevator is given by the following formula;

[tex]Speed = \mathbf{\dfrac{Distance}{Time} }[/tex]

The speed of the elevators are therefore;

[tex]Elevator \ speed \ in \ \mathbf{Empire \ State \ Building} = \dfrac{233 \, ft.}{10 \, s} = 23.3 \, ft./s.[/tex]

[tex]Elevator \ speed \ in \ \mathbf{John \ Hancock \ Center} = \dfrac{150 \, ft.}{5 \, s.} = 30 \, ft./s[/tex]

[tex]Elevator \ speed \ in \ \mathbf{One \ World \ Trade \ Center} = \dfrac{666 \, ft.}{20 \, s.} = 33.3 \, ft./s.[/tex]

[tex]Elevator \ speed \ in \ \mathbf{Space \ Needle} = \dfrac{368 \, ft.}{25 \, s} = 14.72 \, ft./s.[/tex]

[tex]Elevator \ speed \ in \ \mathbf{Willis \ Tower} = \dfrac{401 \, ft.}{15 \, s.} = 26.7\overline{3} \, ft./s. \approx 26.7 \, ft./s.[/tex]

Distance travelled in 12 seconds is therefore;

Distance, d, traveled by the elevator in Empire state building  

d = 23.3 ft./s × 12 s. = 279.6 ft ≈ 280 feet in 12 seconds

Therefore;

Distance traveled in 35 seconds.

Answer:

Figure out the x and y intercepts.

Step-by-step explanation:

you should find what the y or x intercept's are.

To figure that out you need to divide the number next to x or y to 8. use x to find out x intercept and y for y intercept.

lets find out y intercept

8 / -2 = -4

and now x intercept

8 / 3 = 1.75 or 1 (3/4)

Once you found out the intercepts you can now graph the equation.
