Determine the number of real solutions to the quadratic equation -9m^2-8m-3=0
Step-by-step explanation:
Let's solve your equation step-by-step.
−9m2−8m−3=0
For this equation: a=-9, b=-8, c=-3
−9m2+−8m+−3=0
Step 1: Use quadratic formula with a=-9, b=-8, c=-3.
m=
−b±√b2−4ac
2a
m=
−(−8)±√(−8)2−4(−9)(−3)
2(−9)
m=

−18
Answer:
No real solutions.
The given equation has no real solutions.
We have given that the quadratic equation
[tex]-9m^2-8m-3=0[/tex]
For this equation: a=-9, b=-8, c=-3
[tex]-9m^2-8m-3=0[/tex]
Step 1: Use quadratic formula with a=-9, b=-8, c=-3.
What is the formula for the quadratic roots?[tex]x=\frac{-b \±\sqrt{b^2-4ac}} {2a}[/tex]
Therefore we have,
[tex]x=\frac{-b \±\sqrt{b^2-4ac}} {2a}[/tex]
[tex]x=\frac{-(-8)\±\sqrt{(-8)^2-4(-9)(-3)} }{2(-9)}[/tex]
[tex]x=-\frac{4}{9} -i\frac{\sqrt{11} }{9}[/tex] and [tex]x=-4/9+i\frac{\sqrt{11} }{9}[/tex]

If your claim is in the alternative hypothesis and you fail to reject the null hypothesis, then your conclusion would be:
Answer:
There is not sufficient proof to support the claim.This is a type II error.
Step-by-step explanation:
This is the type II error where the null hypothesis is wrong. But as you have failed to reject the null hypothesis and would not accept the alternate hypothesis it is type II error.
It means that there is not enough statistical evidence to prove your alternative claim.Your claim cannot be accepted or supported through given statistical data.
There is not sufficient proof to support the claim.
When null hypothesis is false then the wrong decision gives a type II error.

c. right shift 3 units
d. shift upward 4 units
Step-by-step explanation:
It is a good idea to become familiar with what these various factors do. You will see them repeatedly.
__
a. Multiplying a function by a negative value reflects its graph over the x-axis.
__
b. A multiplier of 2 will expand the graph vertically by a factor of 2.
__
c. Subtracting 3 from each x-value will shift the graph right 3 units.

Given a line with slope of 5 and y-intercept of -1, which of the ordered pairs given below would NOT be on the line?
O (4.18)
(3, 14)
O (0-1)
O (2.9)
Answer:
(4, 18)
Step-by-step explanation:
We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.
1. y = 5(4) - 1
= 20 - 1
= 19 (Nope, 18 is not 19)
2. y = 5(3) - 1
= 15 - 1
= 14 (Yep, same as option)
3. y = 5(0) - 1
= 0-1
= -1 (Yep, same as option)
4. y = 5(2) - 1
= 10 - 1
= 9 (Yep, same as option)
The point (4, 18) is not lies on the given line.
First option is correct.
The equation of line in slope intercept form is,
[tex]y=mx+c[/tex]
Where m is slope and c is y intercept.
Given that, m = 5 and c = -1
Substitute above values
Equation of line is,
[tex]y=5x-1[/tex]
Substitute first option (4, 18) in equation of line.
[tex]18=5(4)-1\\\\18=20-1\\\\18=19[/tex], which is invalid equation.
Hence, point (4, 18) is not lies on the given line.

Four different stores sell packages of organic brown rice. The prices at each store are shown in the table.
Which store has the lowest price per pound?
A. Eat Right Grocery
B. Good Food Market
C. Health First Store
D. Food for Life Market
================================
Work Shown:
For each store, divide the cost over the size to get the unit price.
Eat Right Grocery: 2.32/2 = 1.16Good Food Market: 3.70/3 = 1.23Health First Store: 5.65/4 = 1.41Food for Life Market: 7.28/5 = 1.46Round each result to the nearest penny. We see that Eat Right Grocery has the lowest unit price, or price per pound.
----------------------
Further explanation:
Let's look at the first row of the table. This says that 2 pounds of rice cost 2.32 dollars. We can form an equation of sorts
2 pounds = 2.32 dollars
Divide both sides by 2 to turn that "2 pounds" into "1 pound". This is because "price per pound" really means "price per 1 pound" or "price for each 1 pound"
So we get
2 pounds = 2.32 dollars
2/2 pounds = 2.32/2 dollars
1 pound = 1.16 dollars
Telling us the unit cost for Eat Right Grocery is $1.16 per pound. The other stores unit prices are calculated the same way.
