Answer:

Given:-

Y = 3x² - 3x + 2

Find : - Discriminant

Y = ax² - bx + c

Discriminant is : - Y = b² - 4ac

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.

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)

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

The solutions are all the points strictly larger than 5, to represent this, we draw an open circle at x = 5, and a bold line that points to the right.

Here we have the inequality:

–3(2x – 5) < 5(2 – x)

First, we need to isolate x in one side of the inequality, we will get:

-6x + 15 < 10 - 5x

15 - 10 < -5x + 6x

5 < x

Then the solutions are all the points strictly larger than 5, to represent this, we draw an open circle at x = 5, and a bold line that points to the right.

Step-by-step explanation:

y = mx + b <== slope-intercept form of a straight line

m <== slope of the line

b = y-intercept (when x = 0)

y = -4x + 5

Therefore, for this line, the y-intercpet is (0,5)

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 statements that are true about the considered polynomial are:

Greatest common factor, as the name implies, is greatest among all common factors among the quantities given.

We can factorize the quantities in smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could. Those will together compose GCF(Greatest common factor).

The considered polynomial is: 28vw + 49v + 35w

Checking all the options:

False.

Coefficients are numbers in multiplication with variables in each term.

The coefficients of the considered polynomial are 28, 49, 35

They are all multiple of 7 and 1, so the common factor is 7 too, along with 1.

Yes its true.

It is because none of the variables v, or w are in all the three terms.

False.

Thus, the greatest factor that is common in all three terms is 7 and not 7v.

False.

Because, each term written as product of gcf gives:

True.

It is because:

[tex]7(4vw+7v+5w) = 28vw + 49v + 35w[/tex] = the considered polynomial, and that 7 is the gcf.

Thus, the statements that are true about the considered polynomial are:

Answer:

The coefficients have no common factors other than 1.

There are no common variables among all three terms. <----

The GCF of the polynomial is 7v.

Each term written as the product, where one factor is the GCF, is 7(28vw) + 7(49v) + 35(w).

The resulting expression when factoring out the GCF is 7(4vw + 7v + 5w).

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.

Answer:

16 ounces

Step-by-step explanation:

1 pound = 16 ounces. Each clay block is 2 pounds so each of them are 32 ounces.

32 x 3 = 96

Divide 96 by the 4 ounces for each student, 96 ÷ 4 = 24

The clay is only enough for 24 students, leaving 4 students out, each need 4 ounces, so multiply the 4 students by the 4 ounces.

4 x 4 = 16

Therefore, 16 ounces are needed. Hope this helped!
