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
c
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 recipe for whole grain bread calls for 1 oz of rye flour for every 3 oz of whole wheat flour How many ounces of each kind of flour should be used to make a loaf of
bread weighing 22 oz?
Given :
A recipe for whole grain bread calls for 1 oz of rye flour for every 3 oz of whole wheat flour.
To Find :
How many ounces of each kind of flour should be used to make a loaf of
bread weighing 22 oz.
Solution :
It is given that ratio of rye and whole wheat flour is 1 : 3.
Let, amount of rye flour is x and amount of whole wheat flour is 3x.
So, x + 3x = 22
4x = 22
x = 5.5 oz
3x = 16.5 oz
Therefore, amount of rye flour and whole wheat flour is 5.5 and 16.5 oz respectively.
Hence, this is the required solution.
Which is the better buy?
2-quart carton of pineapple juice for $2.00
7-cup carton of pineapple juice for $3.01
Answer:
7-cup carton of pineapple juice for $3.01
Step-by-step explanation:
2-quart carton of pineapple juice for $2.00
2.00 : 2 = 1.00
check your work: 1.00 x 2 = 2.00
so for the first offer you will be paying $1.00 per quart
7-cup carton of pineapple juice for $3.01
1 cups = 0.25 quarts
7 cups = 1.75 quarts
3.01 : 7 = 0.43
check your work: 0.43 x 7 = 3.01
for the second offer you will be paying $0.43 per quart of juice. 7-cup carton of pineapple juice for $3.01 is a better buy because you will be paying less than half of the price for each quart than the first offer.

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%.

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.

Step-by-step explanation:
Angle A measures 4x + 40 degrees and angle B measures x – 10
degrees. If angles A and B are complementary, what is the
measure of angle B?
Answer:
2°
Step-by-step explanation:
Since, angles A and B are complementary.
Therefore,
[tex] m\angle A + m\angle B = 90\degree \\\\
(4x +40)\degree + (x-10)\degree = 90\degree \\\\
(4x+x +40-10)\degree = 90\degree \\\\
(5x +30)\degree = 90\degree \\\\
5x + 30= 90\\\\
5x = 90 - 30\\\\
5x = 60\\\\
x = \frac{60}{5}\\\\
x = 12\\\\
m\angle B = (x-10)\degree \\\\
m\angle B = (112-10)\degree \\\\
m\angle B = 2\degree \\\\[/tex]
The teacher asked Jenny's class to solve the equation $5x - 6 = 4x + 9$. Jenny copied the coefficient of $x$ on the right-hand side incorrectly and wrote down a different equation. 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:
15
Step-by-step explanation:
5x - 6 = 4x + 9
+6 + 6
5x = 4x + 15
-4x - 4x
x = 15

Step-by-step explanation:
A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. He wants to construct the 95% confidence interval with a maximum error of 0.09 reproductions per hour. Assuming that the mean is 6.6 reproductions and the variance is known to be 4.84, what is the minimum sample size required for the estimate? Round your answer up to the next integer.
Answer:
The minimum sample size is [tex]n = 2295 [/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is [tex]E = 0.09[/tex]
The sample mean is [tex]\= x = 6.6[/tex]
The variance is [tex]\sigma^2 = 4.84[/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{\sigma^2}[/tex]
=> [tex]\sigma = \sqrt{4.84 }[/tex]
=> [tex]\sigma = 2.2[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2[/tex]
=> [tex]n = [\frac{1.96 * 2.2 }{0.09} ] ^2[/tex]
=> [tex]n = 2295 [/tex]

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
