What value goes in cell B?

No.

When you divide by a positive value you do not flip the inequality, only when dividing by a negative value.

2x < -6

To solve for c you divide both sides by 2, which is a positive value so the inequality stays the same:

X < -6/2

X < -3

Answer:

y=-1/3x+5

Step-by-step explanation:

to find the slope you have to use the equation y₂-y₁/x₁-x₂

which will give you 6-7/-3-(-6) --> -1/3

the product of this equation is your slope

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]

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: The middle 90% of incomes are between $6621.25 and $12378.75 .

Step-by-step explanation:

The critical z-value for 90% confidence = 1.645

Given: Mean income per household  =  $9500

standard deviation = $1750

then,  middle 90% of incomes are between $(9500-(1.645)(1750)) and (9500+(1.645)(1750))

i.e.  middle 90% of incomes are between $6621.25 and $12378.75.

Hence, the middle 90% of incomes are between $6621.25 and $12378.75 .

Answer:

(w * 2) + 5 = 9

Explanation:

Product means multiplication. Five more than means adding 5. So, add five to the answer of w times 2 is 9.

(w * 2) + 5 = 9

Thus the equation is 5 + 2w = 9 and the unknown number is 2.

Given,

Five more than the product of a number and 2 equals 9.

We will use the unknown number as w.

We will form an equation.

Find the equation.

Let the unknown number be w.

"Five more than the product of a number and 2 equals 9".

we can write this as:

5 + w x 2 = 9

5 + 2w = 9

Find the unknown number.

We have,

5 + w x 2 = 9

5 + 2w = 9

Subtract 5 on both sides.

5 + 2w - 5 = 9 - 5

2w = 4

Divide both sides by 2.

w = 2

Thus the equation is 5 + 2w = 9 and the unknown number is 2.

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]

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

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:

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.

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

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:

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.
