ABM is 60; DBC is 60; CBM is 120; HGF is 120; EFM is 120

Step-by-step explanation:

Given the sample table below:

Total number of teenagers that get less than 8 hours of sleep each school night

Sample #1:

The number of teenagers that get less than 8 hours of sleep each night include the sum of teenagers that get less than 4 hours, teenagers that get between 4 and 6 hours, teenagers that get between 6 and 8 hours.

Thus, we have

Sample #2:

Thus, we have

Percentage of teenagers that get between 4 and 10 hours of sleep each school night

ample #1:

The total number of teenagers that get between 4 and 10 hours of sleep is evaluated to be

Thus, the percentage becomes

Sample #2:

Hence, based on the result of the survey,

About half of the teenagers get less than 8 hours of sleep each school night,

More than 90% of teenagers get between 4 and 10 hours of sleep each school night.

Answer:

y = (7/4)x + 2

Step-by-step explanation:

(-4, -5) and (0, 2)

(x₁, y₁) (x₂, y₂)

y₂ - y₁ 2 - (-5) 2 + 5 7

m = ------------- = ------------- = ------------- = --------

x₂ - x₁ 0 - (-4) 0 + 4 4

(it doesn't matter which points you put)

y - y₁ = m(x - x₁)

y - 2 = (7/4)(x - 0)

y - 2 = (7/4)x - 0

+2 +2

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

y = (7/4)x + 2

The graph of the linear function w(x) = 0.6x+2 has been plotted

The given linear function is

w(x) = 0.6x+2

The domain is the set of all possible inputs of the functions.

The range is the set of  all possible outputs of the functions

Here we will substitute some values of x that is the domain of the function and the result will be the range of the function

w(-3) = 0.6×-3+2

= 0.2

w(-2) = 0.6×-2+2

= 0.8

w(-1) = 0.6×-1+2

= 1.4

w(0)  = 0.6×0+2

= 2

w(1) = 0.6×1+2

= 2.6

w(2) = 0.6×2+2

= 3.2

w(3) = 0.6×3+2

= 3.8

Plot the graph using the domain and range

Hence, the graph of the linear function w(x) = 0.6x+2 has been plotted

The line which is parallel to 2x-2y=-4 that passes through the

point (3,9) is x-y = -6.

Given that, 2x-2y = -4 passes through the point (3,9) then we have to find the equation of a line which is parallel to the given equation of line.

Let's proceed to find the equation of the line.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).

Using the slope-intercept formula, the equation of the line is:

y = mx + b

where,

m = the slope of the line

b = y-intercept of the line

(x, y) represent every point on the line

x and y have to be kept as the variables while applying the above formula.

2x-2y = -4

-2y = -4-2x

y = -4/-2 - 2x/-2

y = 2+x

y = x+2

On comparing with y = mx+b

m = 1 and b = 2

As the lines are parallel then the slope of other line will also be same i.e., m = 1

The point from which it is passes is (3,9)

⇒ x₁ = 3 and y₁ = 9

y-y₁ = m(x-x₁)

⇒ y-9 = 1(x-3)

⇒ y-9 = x-3

⇒ y = x-3+9

⇒ y = x+6

⇒ x-y = -6

Therefore, the line which is parallel to 2x-2y=-4 that passes through the

point (3,9) is x-y = -6.

Hence, x-y = -6 is the required answer.

Point (C) C closely approximates the given mathematical operation that is the difference between B and A (B - A).

So, when we add up 2 numbers let's say A and B, the result is always a 3rd number which is C.

Similarly, when we subtract a number from another number (B - A), the result is always a third number C.

So, (C) C closely approximates the difference between B and A (B - A).

Therefore, point (C) C closely approximates the given mathematical operation that is the difference between B and A (B - A).

The insurance company will pay $10000 while Roger's share will be $4800 and therefore he must pay $4,800 in the insurance claim.

From the information, Roger Laut, who lives in Territory 5, carries 10/20/5 compulsory liability insurance along with optional collision that has a $1,000 deductible.

An insurance claim is a formal request for payment for losses protected by your insurance policy. A contract between you and your insurer is known as an insurance policy. You must pay a predetermined premium. With a $5,000 maximum limit on property damage, the insurance provider will pay losses up to $10,000 for one injured or killed person and up to $20,000 for several persons. This slab is for any accident.

Roger's share will be $4800 because the cost of repairing the other car is only expected to be around $4800. He's got $4,800 to pay.

Answer:

The number is 5.

Step-by-step explanation:

Let x be the number.

[tex]3x - 8 = x + 2[/tex]

[tex]2x = 10[/tex]

[tex]x = 5[/tex]

The composition of functions evaluated in x = 3 is equal to -8.

t(3) = -8.

Here we have the two functions g(x) and f(x), and the composition:

(g°f)(x) = t(x).

This is equal to:

t(x) = g(f(x))

Then:

t(3)  = g( f(3) )

Evaluating f(x) in 3 we get:

f(3) = 4*3-  6 = 12 - 6 = 6

Then:

t(3) = g( f(3))  =g(6)

And we know that g(6) = -8, then:

t(3) = -8.

Step-by-step explanation:

Area of the rhombus in terms of given diagonals:

Plug in the values and calculate:

The only quantities that will be directly proportional are; A) distance and time traveled if speed is a constant 77 mph

Direct proportionality means the change of a similar kind.

For example, as pressure increases, density also increases, which means both the parameters (pressure and density) are experiencing a similar kind of change i.e. increment in their magnitude.

Looking at the given options;

A) Distance and time traveled if speed is a constant 77 mph.

Now, formula for speed is;

Speed = Distance/Time

Thus, if speed is constant, then it means that distance varies  directly with the time because as distance increases, then time also increases.

B) We are told that the distance traveled is 110 miles.

Distance = Speed * time.

Thus, speed and time vary indirectly with the time because as one increases, the other decreases

C) Since the amount of money spent is constant, then it means that;

The zeroes of the function k(x)=15x³-48x²-48x are 0, 4 and -4/5.

The function provided is a cubic polynomial.

There will be three zeroes in total for the function k(x).

K(x) = 15x³-48x²-48x

If we put x = 0,

We can see that k(x) becomes zero,

So we can say that 0 is a solutions for this function,

Now,

K(x) = x(15x²-48x-48)

Solving 15x²-48x-48 seperately using quadratic formula,

a = 15

b = -48

c = -48

x = (-b+√D)/D and (-b-√D)/D

D = b²-4ac.

D = (-48)²-4(15)(-48)

D= 5184.

√D = 72

putting all the values to find x,

x = (-(-48)+72)/30 and (-(-48)+72)/30

x = 4 and -4/5.

our function becomes,

k(x) = x(x-4)(x+4/5)

so the zeroes are 0, 4, -4/5.
