Answer:
y = - 4.4
Step-by-step explanation:
Given that t varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6.6 when x = 9.9 , that is
- 6.6 = 9.9k ( divide both sides by 9.9 )
k = [tex]\frac{-6.6}{9.9}[/tex] = - [tex]\frac{2}{3}[/tex]
y = - [tex]\frac{2}{3}[/tex] k ← equation of variation
When x = 6.6, then
y = - [tex]\frac{2}{3}[/tex] × 6.6 = - 2 × 2.2 = - 4.4

Step-by-step explanation:
Evaluate 6x – 6xy
When x = 8, y = 1
Answer:
0
Step-by-step explanation:
We know the values of x and y so we just need to substitute them in:
6(8) - 6(8 × 1)
= 48 - 48
= 0
y = 1/3x + 5 m b = (0, )
Answer:
5
Step-by-step explanation:
When we have an equation in slope-intercept form, it's put in the form
[tex]y = mx+b[/tex]
Where m is the coefficient (the slope) and b is the y-intercept.
Since we are trying to find the y-intercept based on this equation (that's why it says [tex]b=[/tex] ), we can use the equation to find the y-intercept.
The slope is [tex]\frac{1}{3}[/tex] since that's the coefficient next to x.
The constant being added is 5, therefore this is the y-intercept.
Hope this helped!
A coin is tossed twice. Determine whether the events of getting tails twice are independent or dependent. Then identify the indicated probability.
Answer:
Hi there!
They are independent. The first toss does not change the outcome of the sides. If you have a fair coin it's 50-50 weight.
1/2 × 1/2 = 1/4
There's a 25% chance of getting tails twice
The point (1,-4) is on the line given by which equation below?
A. y=-2x
B. y=-4x
C. Y=x-4
D. y=4x
Answer:
B. y = -4xStep-by-step explanation:
(1, -4) ⇒ x = 1, y = -4
A. x=1 ⇒ y = -2•1 = -2 ≠ -4
B. x=1 ⇒ y = -4•1 = -4
C. x=1 ⇒ y = 1 - 4 = -3 ≠ -4
D. x=1 ⇒ y = 4•1 = 4 ≠ -4

factorize the expression: 9x^4 + 12x^2y + 4y^2
Answer:
(3x² + 2y)²
Step-by-step explanation:
Given
9[tex]x^{4}[/tex] + 12x²y + 4y² ← a perfect square
9[tex]x^{4}[/tex] = (3x²)² and 4y² = (2y)²
of the form

Which of the following would be considered practically? significant?
A. An average of 1.2 pounds was lost over a 12 month period using a new diet program.
B. In a very large? study, it was found that Treatment I resulted in? 93% success while Treatment II resulted in? 75% success.
C. 8 out of 14 births resulted in male children.
D. 1 out of 50 people were not smoking 12 months after completing a? non-smoking program.
Answer: B. In a very large? study, it was found that Treatment I resulted in? 93% success while Treatment II resulted in? 75% success.
Step-by-step explanation: The significance of a treatment, process or procedure in terms practicality lies in the logical assessment of such process as to whether it has a tangible or worthwhile impact. Based on the list of treatments or experiments above, the treatment which could be considered to have had a huge or significant impact is that which has 93% and 75% success rate on treatment 1 and 11 respe tivwly having considered that the study was said to be a very large one. Hence, going by large number of participant involved and a success rate with such high percentage, then the study could be said to possess practical significance.
The result that would be considered practically significant is: B. In a very large study, it was found that Treatment I resulted in? 93% success while Treatment II resulted in? 75% success.
What is a Significant Result?A significant result is that in which the outcome cannot be based on chance. Such a result satisfies all conditions required and leaves no room for doubt.
The result obtained above can be deemed to be statistically significant because a very large percentage of the two treatments achieved the purpose for which they were engineered.
The success is very significant and cannot be attributed to mere chance.

the length of a rectangle is 6 inches more than twice it's width.If the perimeter of a rectangle is 60,find it's dimensions.
Answer:
length = 22 incheswidth = 8 inchesStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 60 in
The statement
the length of a rectangle is 6 inches more than twice it's width is written as
l = 6 + 2w
Substitute the statement into the above formula
That's
60 = 2( 6 + 2w) + 2w
60 = 12 + 4w + 2w
6w = 60 - 12
6w = 48
Divide both sides by 6
w = 8
Substitute w = 6 into l = 6 + 2w
That's
l = 6 + 2(8)
l = 6 + 16
l = 22
The dimensions are
length = 22 inches
width = 8 inches

Answer:
- 6p - 21
Step-by-step explanation:
Property used: a(b+c) = ab + ac
-6( -3p + 6 ) + 3( -8p + 5 ) = (-6)(-3p) + (-6)(6) + 3(-8p) + 3(5) =18p - 36 - 24p + 15 =(18 - 24)p - (36 - 15) = - 6p - 21What is meant by “offensive is not illegal”?
Answer:
It depends on the country and it depends on the act itself.
In US, there is such thing as freedom of speech (with some common-sense limitations), however same will get a person thrown in jail and sentenced to death in a country where any speaking out is deemed as illegal.
So, are you planning on offending someone by calling them stupid or are you planning on violating someone's religious beliefs by desecrating their house of worship?
Are you planning on showing an adult film to a bunch of kids or are you going to tell kindergarteners that Santa is not real?
Upset feelings are not exact damages to be shown in court to demand compensation, however a damage to one's reputation or causing a financial loss (or a loss of life if that offense goes too far) would land that person in legal trouble.
