What is Number line?

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

Given that;

A number line shows 'a' to the left of 0 and 'b' to the right of 0. Point a is closer to 0 than point b.

Now,

Since, Point a is closer to 0 than point b.

And,  Number 'a' to the left of 0 and 'b' to the right of 0.

Hence,

Let the number 'a' = - 1

Then, The number 'b' = 2

So, We get;

|a| = |-1| = 1

And, |b| = 2

Clearly, |a| < b

Thus, The incorrect statement for the given condition is;

⇒ |a| > b

Step-by-step explanation:

Answer:

You need to use y=mx+b

In this case, m=1.5 so that means that y=1.5x

Now you must find out the y intercept which is "b" in y=mx+b

I think it is the first one (y=1.5x+72)

====================================================

Explanation:

The given slope is m = 1.5

We want the line to go through (x,y) = (6,72). This means x = 6 and y = 72 pair up together.

We'll plug those m, x, and y values into the equation below to solve for b

y = mx+b

72 = 1.5*6+b

72 = 9+b

72-9 = b ... subtract 9 from both sides

63 = b

b = 63 ... y intercept

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

Since m = 1.5 and b = 63, we go from y = mx+b to y = 1.5x+63

Answer:

-9

Answer:

The value is [tex]P(60 < X < 70) = 0.34134[/tex]    

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 1 \ hour = 60 \ minutes[/tex]

    The standard deviation is  [tex]\sigma = 10 \ minutes[/tex]

Generally the 1 hour is equivalent to 60 minutes

   Generally the probability to complete the job in one hour or more, but less than 70 minutes is mathematically represented as

    [tex]P(60 < X < 70) = P(\frac{60 - 60 }{10 } < \frac{X - \mu}{\sigma } < \frac{70 - 60 }{10 } )[/tex]

=> [tex]P(60 < X < 70) = P(0 < \frac{X - \mu}{\sigma } < 1 )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

=> [tex]P(60 < X < 70) = P(0 <Z < 1 )[/tex]

=>     [tex]P(60 < X < 70) = P(Z < 1) - P(Z < 0 )[/tex]

From the  z  table  (Z <  1)  and  (Z <  0 ) is  

        [tex]P(Z < 1) = 0.84134[/tex]

and  

      [tex]P(Z < 0 ) = 0.5[/tex]

=>    [tex]P(60 < X < 70) = 0.84134 - 0.5[/tex]

=>    [tex]P(60 < X < 70) = 0.34134[/tex]        

Answer:

94 grams

Step-by-step explanation:

Adrian gerbil weighed 68.59 grand at the beginning of the summer

During the summer the gerbil gained 24.6 grams

Therefore the weight of the gerbil at the end of the summer can be calculated as follows

= 69 + 25

= 94 grams

Therefore the weight of the gerbil at the end of the summer is 94 grams

Answer:

A quadratic equation has solutions when the graph crosses the x-axis. There are two ways the graph can have no solution, when the "a" value is greater than 0 and is translated vertically above the x-axis, or if the opposite occurs, when the "a" value is negative and is translated vertically below the x-axis.

Step-by-step explanation:

[tex]y - y1 = m(x - x1)[/tex]

[tex]y - ( - 4) = \frac{3}{2} (x - ( - 1)[/tex]

[tex]y = \frac{3(x + 1) - 8}{2} [/tex]

[tex]y = \frac{3}{2} x - \frac{5}{2} [/tex]

Answer:

  p(x) = x^4 -8x^3 +16x^2 -8x +15

Step-by-step explanation:

Assuming you want real coefficients, the imaginary root means its conjugate is also a root. In factored form, the polynomial is ...

  p(x) = (x -3)(x -5)(x -i)(x +i) = (x^2 -8x +15)(x^2 +1)

  p(x) = x^4 -8x^3 +16x^2 -8x +15

Answer:

Step-by-step explanation:

Answer:

Starting price is $50.70.

Next day the price is $50.70 + $17.75 = $68.45

This price then changed by: [tex]-3\frac{3}{4}\%=-3.75\%[/tex].

So in order to calculate that we do: [tex]68.45 - (3.75/100*68.45)=65.883125 =\$65.88[/tex]

Therefore final price is $65.88.

Yes, this is reasonable.

Answer:

C

Step-by-step explanation:

It's y=-4/1-21

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation of the line is y = (-1/2)x + 7

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Let the equation of the line is y = m(1)x + c

The line is perpendicular to 2x - 8y = 3

The means,

2x - 8y = 3

-8y = 3 - 2x

y = -(3 - 2x)

y = -3 + 2x

y = 2x - 3

This is in the form of y = m(2)x + c

m(2) = 2 and c = -3

Now,

The line y = m(1) + c is perpendicular to y = m(2) + c

So,

m(1) x m(2) = -1

m(1) = -1/2

Now,

The line contains (-8, 11) = (x, y).

This means,

y = m(1)x + c

11 = (-1/2) x -8 + c

11 = 4 + c

c = 11 - 4

c = 7

Now,

The equation of the line is y = (-1/2)x + 7

Thus,

The equation of the line is y = (-1/2)x + 7
