Find the least squares regression line for the data points. (Let x be the independent variable and y be the dependent variable.) (−1, 0), (1, −2), (3, −3)
Answer:
y = - 0.9167 - 0.75x
Step-by-step explanation:
Given the data:
(−1, 0), (1, −2), (3, −3)
X : - 1, 1, 3
Y : 0, - 2, - 3
The regression model is written in the form:
y = C + mx
Where ;
C = intercept ; m = slope / gradient
Using the regression model calculator on the data values given above :
Slope (m) = - 0.75
Intercept (c) = - 0.9167
Hence,
y = - 0.9167 - 0.75x

if 2/5 of my money =60 what is 1/5 of my money
Answer:
1/5 of your money is = 30
Step-by-step explanation:
2/5 of your money is equal to 60, so if you divide 60 by 2 you will get 30, which is 1/5 of your money. A way to check if it is right is by multiplying 30 by 5, which is 150, and divide it by 5, to see if it matches (150 : 5 = 30).
hope this helps!
answer:30
explanation:
2/5×X=60
X=150
means your money is 150
so 1/5 of your money is 1/5×150=30
A medical researcher claims that 10 % of children suffer from a certain disorder. Identify the type I error for the test.
a. Reject the claim that the percentage of children who suffer from the disorder is different from 10% when that percentage really is different from 10%.
b. Fail to reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually different from 10%.
c. Fail to reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
d. Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
Answer:
D: Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
Step-by-step explanation:
In statistics, type I error is when we reject the null hypothesis even when it is true.
Now, the claim which is the null hypothesis is that that 10 % of children suffer from a certain disorder.
This means that a type I error will be;
Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
Kelly purchased 6 planters for a total of $18. She wants to purchase another 16 planters at the same unit price. How much will 16 planters cost?
Answer:
$48
Step-by-step explanation:
first you have to divide 18 by three to see how much one costs then multiply that number by 16. that number was 3.
The cost of 16 planters is $48.
Given that, Kelly purchased 6 planters for a total of $18. She wants to purchase another 16 planters at the same unit price.
We need to find how much will 16 planters cost.
What are proportions?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. The proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
Now, let the cost of 16 planters be x.
Then, the proportion is 6:18::16:x
Product of means=18×16
Product of extremes=6×x
So, Product of means=Product of extremes
18×16=6×x
⇒x=288/6
⇒x=48
Therefore, the cost of 16 planters is $48.

Construct parallelogram PQRS
with |PQ|=10cm, |ps|=8cm and
<QPS = 120
Find sketch of parallelogram attached
Answer and explanation:
A parallelogram is a quadrilateral which is wider than it is long. A parallelogram has two sides parallel to the other. From the above, we are told the parallelogram PQRS has an angle QPS 120, with sides 10cm and 8cm, we use this to sketch the parallelogram
We find that angle QPS is 120 degrees hence angle RSP is 60 degrees since angle on straight line is 60 degrees from 180-120 in angle QPS and alternate angles are equal. Also opposite angles of a parallelogram are equal
A box contains 14 large marbles and 11 small marbles. Each marble is either green or white. 8 of the large marbles are green, and 5 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is small or white? Express your answer as a fraction or a decimal number rounded to four decimal places.
Answer:
Step-by-step explanation:
Given that:
Number of Large Marbles = 14
Number of Small Marbles = 11
Number of Green large marbles = 8
Number of White small marbles = 5
We can now find the number of white large marbles and green small marbles from the information stated above.
No of white large marble = total large marble minus green large marble
= 14-8
= 6
No of green small marbles = Total small marbles minus white small marble.
= 11-5
= 6
Let the following be represented
( X,Y, Z,Q ) as follows:
Let Y be the event of drawing small marble
Let X be the event of drawing large marble
Let Q be the event of drawing white marble
Let Z be the event of drawing green marble.
Since, only one marble is drawn at a time we calculate,
P( X ) = 14/25
P( Y) = 11/25
P(Z) = 14/25
P( Q) = 11/25
P(Y∪Q)=P(Y)+P(Z)−P(Y∩Z)...(1)
We need to find the value of
P(Y∩Z)
In 11 small marbles there are 6 green marbles so the value of P(Y∩Z) is given by P(Y∩Z)=6/11
Therefore, substitute the values in equation 1.
P(Y∪Z)=P(Y)+P(Z)−P(Y∩Z)=11/25+14/25-
6/11
=0.44+0.56−0.5455
= 1-0.5455
= 909/2000
= 0.4545
Then, one can conclude that the probability of drawing a small or green marble is 0.4545

Based on recent experience, ten-year-old passenger cars going through a motor vehicle inspection station have an 80% chance of passing the emissions test. Suppose that two hundred such cars will be checked out next week. Find the number of cars that are expected to pass.
Answer:
160
Step-by-step explanation:
The chance/probability of 10-year-old passenger cars passing an emission test is 80%.
200 10-year-old passenger cars will be tested next week.
How many of the 200 cars are expected to pass the emission test?
If there is an 80% chance of them passing the test then it means that 80% of the cars pass the test at any given time.
80% of 200 = 0.8 × 200 = 160
Hence, 160 (of the 200) cars are expected to pass the test.
Jonas is concerned about the amount of water he uses to wash his laundry. he made a table to show the number of gallons of water used by different washing machines to complete of laundry. use variables to represent the independent and dependent shown in the table and Use variables to represent the dependent variable and the independent variable in this sentence

Energy Efficient,
Age of washing Machine (years):
(6,4,2)
and
Gallons Of Water:
(42,28,14)
I do not understand your answer
The exercise asks who are the independent and dependent variables
In the case of Jonas and his washing machine the independent variables are:
Type of Washing Machine.The dependent variables are:
Age of Washing Machine (years).Gallons of Water (42, 28, 14).Energy Efficient.What is an independent variable?The independent variable refers to all those variables that are tested experimentally, being manipulated by researchers in order to test a hypothesis.
Generally, the independent variable has the greatest influence on the result of the experiment, this means that it modifies all the dependent variables.
What is a dependent variable?The independent variable refers to the qualities or characteristics whose behavior is affected by the independent variable. It is about the variable or variables that are measured in order to be able to interpret the results and confirm or discard a hypothesis.
According to the above, it can be inferred that the independent variables in the case of Jonas are the type of washing machine because this variable will directly affect the other variables.
For example, depending on the type of washing machine Jonas uses, it will consume different amounts of energy and will need different amounts of water.

Are AC and DF definitely parallel? How do you know?
Answer:
We know that,
Angle E = 123
Angle B = 57
We observe that,
Angle DEB and Angle E form a linear pair and are supplementary.
Angle DEB + Angle E = 180
Angle DEB = 180-123
=57
We know that if two lines are parallel, the corresponding angles are equal.
Conversely, if the corresponding angles are equal, then the two lines are parallel.
Here,
As Angle B and Angle DEB are corresponding angles are equal in measure (Angle B = Angle DEB = 57), we can say that Line AC and Line DF are parallel.
Step-by-step explanation:
ang B = 180 - 57 = 123°
Since the corresponding angles are equal
So AC and DF are parallel to each other.

Jenny correctly determined that her equation had no solutions. What was the coefficient of $x$ on the right-hand side of Jenny's equation?
Answer:
