So, Discriminant is :-

(-3²) - 4 (3) (2)

= 9-24

=-15

If b² - 4ac < 0.

The equation has no real solution but it does have complex solution.

The area of the triangle is

The area of the rectangle is

The area of the irregular figure is

Answer:

[tex]b=2\frac23\:\sf ft[/tex]

Area of triangle = 4 ft²

Area of rectangle = [tex]6\frac23\: \sf ft^2[/tex]

Area of irregular figure = [tex]10\frac23\: \sf ft^2[/tex]

Answer:

If x2 + 6x + c = (x + d)2, then d =What value of c makes x2 + 6x + c a perfect square trinomial? c =

Divide the x-term coefficient by 2: 6/2 = 3

Now square 3: 3^2 = 9

c = 9

If x^2 + 6x + c = (x + d)^2, then d =

x^2 + 6x + 9 = (x + 3)^2 = (x + d)^2, so d = 3

Step-by-step explanation:

Answer:

c = +9.

Step-by-step explanation:

x^2 + 6x + c.

Divide 6 by 3 then square it

- so c = 3^2 = 9.

x^2 + 6x + 9 = (x + 3)^2.

The dot plot with the least number of sites has the least frequency

The dot plot has the least number of sites is the Shield Darter

To determine the dot plot with the least number of sites, we simply calculate the total frequency of each dot plot

So, we have:

Shield Darter = 3 + 1 + 4 + 2 + 3 + 1 + 1

Shield Darter = 15

Calico Crayfish = 1 + 1 + 3 + 4 + 1 + 2 + 4 + 2

Calico Crayfish = 18

Zebra Mussel = 1 + 3 + 2 + 5 + 1 + 1 + 2 + 3 + 2

Zebra Mussel = 20

Blue back Herring = 3 + 3 + 2 + 1 + 3 + 1 + 4

Blue back Herring = 17

From the computation above, the least frequency is

Shield Darter = 15

Hence, the dot plot has the least number of sites is the Shield Darter

Answer:

C

Step-by-step explanation:

let x be number of adults and y the number of underage , then

x + y = 350 → (1)

6x + 4y = 1600 → (2)

multiplying (1) by - 4 and adding to (2) will eliminate y

- 4x - 4y = - 1400 → (3)

add (2) and (3) term by term to eliminate y

(6x - 4x) + (4y - 4y) = 1600 - 1400

2x + 0 = 200

2x = 200 ( divide both sides by 2 )

x = 100

the number of adults who attended is 100

Step-by-step explanation:

Let the angle of triangle be x , so each angle will be 1x , 2x , 3x respectively.

We know that sum of all angles in triangle is 180°

So ,

1x + 2x + 3x = 180°

6x = 180°

x = 30°

Therefore , each angle would be 30° , 60° , 90° respectively.

Answer:

14130 cubic inches

Step-by-step explanation:

A = 4/3 n x rxrxr

A = 3.14 x 15x15x15

A = 3.14 x 3375

A = 10597.5

A = 4/3 10597.5

A = 14130

C. 2916 Mice

Step-by-step explanation:

4 x 3^6 = 2916

Because as the mice increases, you triple that amount, instead of tripling 4 & multiplying by 6.

So, you're doing this instead:

4 x 3 = 12 (1 wk)

12 x 3 = 36 (2 wk)

36 x 3 =108 (3 wk)

108 x 3 = 324 (4 wk)

324 x 3 = 972 (5 wk)

972 x 3 = 2916 (6 wk)

  B)  When you're finished, you have a line that bisects your segment

Step-by-step explanation:

An angle bisector is a ray that divides a given angle into two congruent parts. There is no line segment involved.

__

The statement that is not true about this construction is ...

  B) When you're finished, you have a line that bisects your segment

_____

Additional comment

The construction effectively creates an arc of a circle, then creates the perpendicular bisector of the chord of that arc. The center of the circular arc is the vertex of the angle being bisected. The constructed perpendicular bisector of the chord also bisects the angle. (The chord is never actually drawn, and the "circular arc" may be two short arcs across the rays of the angle being bisected.)

The number of children who disliked the smoothie is 9, total children is 27, and conditional relative frequency is 33%

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.

From the data given in the table:

The number of children who disliked the smoothie = 9

The total number of children = 27

To find the conditional relative frequency that a customer disliked the new smoothie(if the person is a child)

It is the ratio of total number of children who disliked the smoothie to total number of children, mathematically:

= 9/27

= 0.3333

= 0.3333×100

= 33.33 ≈ 33%

Thus, the number of children who disliked the smoothie is 9, total children is 27, and conditional relative frequency is 33%

Considering that the data has no outliers, the mean of 3.2 inches should be used to describe the center of the data represented in this line plot.

It depends if the data-set has outliers or not.

The dot plot gives the number of times each measure appears. Since there is no outliers, that is, all values are close, the mean should be used. It is given by:

M = (2 x 1 + 3 x 2 + 2 x 3 + 1 x 5 + 1 x 6 + 1 x 7)/(2 + 3 + 2 + 1 + 1 + 1) = 3.2 inches.
