The cost to rent a canoe for 4 hours is $57.

It should be noted that the equation given is illustrated as equation C= 8h+25 represents the cost in dollars, C, to rent a canoe.

C = 8h + 25.

where h = number of hours

C = 8h + 25

When h = 4..

C = 8h + 25

C = 8(4) + 25

C = 32 + 25

C = 57

Therefore, the cost to rent a canoe for 4 hours is $57.

Answer:

Step-by-step explanation:

Given two points on the linear toll function T(d) are (20, 119) and (33, 184), you want the equation for the function T(d), and the value of T(96).

It is usually convenient to write the equation of a line in slope-intercept form when you want to find the value at a particular point. To use that form, we need to know the slope of the line. It is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

Using the given points, we have ...

  m = (184 -119)/(33 -20) = 65/13 = 5

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

Using the first point and the slope we found, the equation is ...

  y -119 = 5(x -20)

Solving the above equation for y, we get ...

  y = 5x -100 +119 . . . . . . . simplify, add 119

  y = 5x +19 . . . . . . . . . . combine terms

Using variables d and T instead of x and y, the function is ...

  T(d) = 5d +19

The value T(96) is ...

  T(96) = 5(96) +19 = 480 +19 = 499

The toll for 96 miles is 499 cents.

The linear equation with  the given information is

2y+2 = 3x+18

Given :

The slope of Parallel Lines:

Slopes of parallel lines are equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal. If the slopes of two parallel lines are represented as m1, m2 then we have

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

The slope of the line can also be represented by

tan θ = Δy/Δx

So, tan θ to be the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘m’

m1 = m2.

y 2/3 = x + 1 ...1

2y = 3x+3

y = 3/2x +3/2

m1= 3/2

x,y = -6,-1

y = mx +b

(y-y1 ) =m (x-x1) +b

m1=m2

m2= 3/2

(y +1) = 3/2 (x+6)

2(y+1 )= 3x+18

the equation of the line that is parallel to y 2/3 = x + 1 and passes through the point (–6, –1) = 2y+2 = 3x+18

The value of a if HL is perpendicular to HJ is 20

From the information given, we have that;

It is important to note that perpendicular lines always intersect each other and the angle between perpendicular lines is equivalent to 90 degrees.

Then, we have that;

Angle 2 + angle 3 =  90 degrees

Substitute the values

a + 15 + a + 35 = 90

collect like terms

2a + 50 = 90

2a = 90 - 50

subtract like terms

2a = 40

Make 'a' the subject

Divide both sides by 2

2a/2 = 40/2

a = 20

Thus, the value of a if HL is perpendicular to HJ is 20

You want the ratio of (7.785×10^10) to (1.5×10^8) expressed in standard form.

  [tex]\dfrac{7.785\times10^{10}}{1.5\times10^8}=\dfrac{7785\times10^7}{15\times10^7}=\dfrac{7785}{15}=\boxed{519}[/tex]

Number of households only own one or more DVD players = 219

Total number of households considered for the survey = 400

Let n(A) represent the number of households only own one or more HDTVs.

Then n(A) = 315

Let n(B) denotes the number of households only own one or more DVD players. We need to find n(B).

Number of households own one or more HDTVs and one or more DVD players, n(A∩B) = 150

Number of households do not own an HDTV or a DVD player = 16

So the number of households which own an HDTV or a DVD player, n(A∪B) = 400 - 16 = 384

Then we have the formula relating n(A∪B), n(A), n(B) and n(A∩B).

n(A∪B) = n(A) + n(B) - n(A∩B)

⇒ n(B) = n(A∪B) - n(A) + n(A∩B)

           = 384 - 315 + 150

           = 219

The number of households only own one or more DVD players = 219

To figure this out, let's set up an equation.

We know 30 people went last year to Universal, and that this is 5 times as many people as who went the year before

So to figure out how many went the year before, we divide 30 by 5

30/5 = 6

So 6 people went to Universal the year before.

With the help of the volume of cube it is concluded that Beth should buy 4 bags of beans.

The volume of a cube is the total three-dimensional space that it occupy. A cube's volume is expressed as cubic units. The SI unit of volume is the cubic meter [tex](m^3)[/tex], which is the volume occupied by a cube with each side measuring 1 m.

The first thing to do in this case is to find the volume of the cube, which will be given by:

V = [tex]L ^ 3[/tex]

where, L = sides of the cube.

Substituting we have:

V = [tex](2) ^ 3[/tex]

V = [tex](8) ^ 3[/tex]

Since, beans are sold in bags that hold two cubic feet of beans.

Step-by-step explanation:

a. The weight of a particular crate such that the probability of randomly selecting a heavier crate is 0.05 is 16.30kg.

b. The probability that a randomly selected crate will weigh more than 16kg is 0.0764.

c. The probability that.at least 2 of them will weigh more than 16kg is 0.4584.

a. From the information, there is a mean of 14 kg and a standard deviation of 1.4 kg. The weight will be:

Let the weight = x

X = (Z × mean × standard deviation)

= (1.645 × 1.4 ×14)

= 16.30kg

b. The probability that a randomly selected crate will weigh more than 16kg will be:

P(z > 16)

= P(Z > 16-14/1.40)

= P(Z > 1.43)

Looking under the normal distribution table, the value is 0.0764.

c. The probability that at least 2 of them will weigh more than 16kg when 20 crates are randomly and independently selected will be through binomial distribution where n = 20 and p = 0.0764.

This will give a value of:

= 1 - 0.5416

= 0.4584

Therefore, the probability that.at least 2 of them will weigh more than 16kg is 0.4584.

Answer:

3.9 x [tex]10^{8}[/tex]

Step-by-step explanation:

0.39 is not in scientific notation.  For a number to be in scientific notation the first factor has to be 1 or greater, but less then 10.  0.39 is less than one.

First we must write 0.39 in scientific notation.  We need to move the decimal so that the number is greater than 1, but less than ten.  If we move the decimal one place to the right, we get 3.9.  The standard number is smaller than 3.9.  How much smaller?  [tex]10^{-1}[/tex] smaller.

0.39 in scientific notation would be 3.9 x [tex]10^{-1}[/tex].  We cannot forget the [tex]10^{9}[/tex], so our number looks like this now:

3.9 x [tex]10^{-1}[/tex] x [tex]10^{9}[/tex]  The product of powers principle tells us that if we have powers with the same bases, we can add the exponents.
