Answer:
x = 6 and x = -1.
Step-by-step explanation:
The given equation is :
[tex]6x^2-30x=36\\\\6x^2-30x-36=0\\\\or\\\\x^2-5x-6=0[/tex]
We can solve it using the middle term splitting method.
[tex]x^2-(6x-x)-6=0\\\\x^2-6x+x-6=0\\\\x(x-6)+1(x-6)=0\\\\(x-6)=0\ and\ (x+1)=0\\\\x=6\ and\ x=-1[/tex]
So, the solutions are x = 6 and x = -1.

Answer:
68°
Step-by-step explanation:
Since angle 1=68° and angle 5 is a corresponding angle, thus, angle1=angle 5
therefore angle 5 is 68°
Researchers studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group.
(a) Identify the population of interest and the sample in this study.
(b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
A) Population of interest = children between the ages of 5 and 15
Sample = 160 children between the ages of 5 and 15.
B) Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.
Yes, the findings can be used to establish causal relationship because the study is just an experiment.
Step-by-step explanation:
A) Population of interest = children between the ages of 5 and 15
Sample = 160 children between the ages of 5 and 15.
B) Sample size is 160 which is above 30.
Thus, we can say;
Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.
Yes, the findings can be used to establish causal relationship because the study is just an experiment.

Answer:
60
Step-by-step explanation:
I think that is the best choice sorry if i got it wrong.
Answer:
60 degrees
Step-by-step explanation:
Angle 1 is already 55 degrees, if you move the y line 5 degrees clockwise then it equals 60 degrees. Angle 1 and 3 are vertical angles so they are equal, if angle 1 is 60 degrees after we move the line then angle 3 is also 60 degrees

Given f(x) = 5x4 – x2 + 6x – 1. What is Limit of f (x) as x approaches negative 1?
–3
–13
–25
–29
Answer:
-3
Step-by-step explanation:
The limit of the given function f(x) = 5[tex]x^{4}[/tex] – x2 + 6x – 1 approach negative 1 will be -3 so correct option will be (A).
What is limit?Limit, a nearness in mathematical notion, is largely used to give values to some functions at locations that were usually not given or defined, in a manner consistent with neighboring values.
In another word, limit is a mathematical concept in which we find out the value of any function at a point by its adjacent very close point.
Because the value of that function at that point doesn't define.
For example, limits tend to 0 of sine x, limits tend to infinite of cosx.
Given that the function
5[tex]x^{4}[/tex] – x2 + 6x – 1
Limit is from x is tends to -1
[tex]\lim_{x \to \-1} f(x)[/tex] = 5(-1)⁴ - (-1)² +6(-1) -1
⇒ -3 hence it will be the correct answer.

hi guys what is and can u please do the method 4050 divided by 100
Answer:
40.5
Step-by-step explanation:
what i do is I divided first by 10. because 100 is 10x10.
so 4050 divided by 10 is 405.
405 divided by 10 is 40.5
4050 divided by 100 = 40.5

convert 0.5t5kg5hg to kilogram
Answer:
505.5kg
Step-by-step explanation:
To convert 0.5t5kg5hg to kilogram, first we need to convert 0.5t and 0.5hg to kg as shown;
1t = 1000kg
0.5t = 0.5 *1000
0.5t = 500kg
Similarly
1hg = 0.1kg
5hg = 5 * 0.1
5hg = 0.5kg
Adding up;
0.5t5kg5hg = 500kg+5kg+0.5kg
0.5t5kg5hg = 505.5kg
Hence the conversion to kg is 505.5kg

Find lateral surface
area of the play tent.
h = 4 in
14 in
5 in
5 in
W
6 in
Answer:
224 in.²
Step-by-step explanation:
The tent has a shape of a triangular prism. So, we are looking for the Lateral surface area of a triangular prism.
Lateral surface area of a triangular prism = Perimeter of base × height of prism
Perimeter of base = 5 + 6 + 5 = 16 in.
Height of prism = 14 in.
Plug in the values
Lateral Surface Area = 16 × 14 = 224 in.²

Write your answer as a comma-separated list ordered from smallest to largest value. possible values: List the probabilities that X Y takes each of the values. Write your answer as a comma-separated list giving the probabilities in the same order as in (a)
Answer:
a) 0 , 1
b) 0.56 , 0.06
Step-by-step explanation:
X = 0.2
Y = 0.3
Find the distribution of X + Y
a) All the possible values of X + Y
The possible values of X + Y are ; 0,1
b) The probabilities that X + Y takes each of the values
P(X+Y=0 ) = ( 1-0.2 )*(1-0.3) = 0.56
P( X +Y = 1) = 0.2*0.3 = 0.06

Given the figure below, find EF if CA = (6n) and EF = (n + 8)
Answer:
[tex]EF = 12[/tex]
Step-by-step explanation:
Given
[tex]CA =6n[/tex]
[tex]EF= n + 8[/tex]
Required
Find CN
From the attachment:
[tex]EF = CD\ and\ CD = DA[/tex]
Where
[tex]CA = CD + DA[/tex]
This means that:
[tex]CA = CD + CD[/tex]
[tex]CA = 2CD[/tex]
or
[tex]CA = 2*EF[/tex]
This gives:
[tex]6n = 2*(n+8)[/tex]
Open bracket
[tex]6n = 2n+16[/tex]
Collect anf simplify like terms
[tex]4n = 16[/tex]
[tex]n= 4[/tex]
So:
[tex]EF= n + 8[/tex]
[tex]EF = 4 + 8[/tex]
[tex]EF = 12[/tex]
