Answer:
c
Step-by-step explanation:
Think of it like this. When you convert a percent to a decimal, just put a decimal point before the number. For example, 40%. You would put . before 40, making it 0.40, and you don't need the zero, so it becomes 0.4. For something like 8%, you would first put a zero before the 8, and then put a period before the zero, like so: 8%= 08%=0.08
NEED HELP QUICK!!!!! A set of data includes the point (17,3.8) and has the regression equation y=-25x+436. What is the residual for this point
Given:
The regression equation is:
[tex]y=-25x+436[/tex]
The given point is (17,3.8).
To find:
The residual for the given point.
Solution:
We have,
[tex]y=-25x+436[/tex]
Substituting [tex]x=17[/tex], we get
[tex]y=-25(17)+436[/tex]
[tex]y=-425+436[/tex]
[tex]y=11[/tex]
The predicted value at [tex]x=17[/tex] is 11.
The given point is (17,3.8). It means the observed value at [tex]x=17[/tex] is 3.8.
Formula for residual:
Residual = Observed value - Predicted value
Residual = [tex]3.8-11[/tex]
Residual = [tex]-7.2[/tex]
Therefore, the residual for the given point is -7.2.

Answer:
The second one
Step-by-step explanation:
A visual for law of sines can be found below
Sin (an angles) over its opposite side length is equal to sin ( a different angle) over its opposite side length
In the given triangle we are given side length BC and side length AB
we are also given AB's opposite angle (40)
And we need to find side length BC's opposite angle (A)
That being said we are given enough information to set up an equation using the law of sines
Remember angle A's opposite side length is 16 and the angle that has a measure of 40 degrees' opposite side length is 12
so the equation would look like...
[tex]\frac{sin(40)}{12} =\frac{sin(A)}{16}[/tex]
What is the value of a missing angle
Answer:
63°
Step-by-step explanation:
First, by looking at the angle we see that the overall angle is a right angle. This means that the total will add up to 90°.
Knowing this we can then subtract
90° - 27° = 63°
Answer:
63
Step-by-step explanation:
The measure of a right angle is always 90 so
90-27=63

Which of the following is the concept illustrated with the misentered data? A. The procedure for constructing the confidence interval is robust. The larger the sample size, the more resistant the mean. Therefore, the confidence interval is less robust. B. The procedure for constructing the confidence interval is robust. The larger the sample size, the more resistant the mean. Therefore, the confidence interval is more robust. C. The procedure for constructing the confidence interval is not robust. The smaller the sample size, the less resistant the mean. Therefore, the confidence interval is more robust.
Answer: B. The procedure for constructing the confidence interval is robust. The larger the sample size, the more resistant the mean. Therefore, the confidence interval is more robust.
Step-by-step explanation:
Large sized data samples usually have more stability than data with small samples, they yield a mean value which edges closer to the value of the population data. This means that large size data samples will have a mean which is more resistant to change than samples with a lower sample size. The confidence interval gives robustness while constructing a model by giving te leverage for a range of values based in a certain level of confidence upon which a statistical vale can be tested for validity.
1. Write the absolute value inequality in the form x−b≤c or x−b ≥c that has the solution set −1≤x≤3.
2.Write the absolute value inequality in the form x−b≤c or x−b≥c that has the solution set x≤−9 or x≥−5.
WILL BE MARKED BRAINLEIST!
Answer:
1. We want to write an equation in the form:
Ix - bI ≤ c
Such that the solutions are the range −1 ≤ x ≤ 3
First, the extremes of the range are: - 1 and 3
Half of the difference between these values is:
m = (3 - (-1))/2 = (3 + 1)/2 = 4/2 = 2
Now let's go to the lower extreme, and add this value, we get:
-1 + m = -1 + 2 = 1
(if we go to the upper value and we subtract m, we get the same)
This is the mid-value of the solution interval, and we will define it as M
We now can write the absolute value inequality as:
I x - MI ≤ m
In our case, we get:
Ix - 1I ≤ 2
2.
Now we want to have the solution set given by:
x ≤ -9
x ≥ -5
In this case, we will have an equation of the form:
Ix - MI ≥ m
(before we used the symbol ≤, which means that the solutions are inside the interval, now we use the symbol ≥, which means that the solutions are outside of the interval (-9, -5) in this case).
So let's do the same than in the above case:
m = (-5) - (-9) = (-5 + 9)/2 = 4/2 = 2
M = -9 + 2 = -7
Replacing these in the absolute value inequality we got:
Ix - (-7)I ≥ 2
Ix + 7I ≥ 2

Rewrite y= 7/16x+14 in standard form
Answer:
7x - 16y = -224
Step-by-step explanation:
Standard Form:
Ax + By = C
y= 7/16x+14
-7/16x + y = 14
(Multiply everything by 16)
-7x + 16y = 224
(Multiply everything by -1)
7x - 16y = -224
If 4 children drink 24 ounces of milk everyday then how much do they drink in a week? (if this shows up twice sorry i didn't know)
Answer:
168
Step-by-step explanation:
24x7=168
Answer:
In total, the amount of milk every kid combined drank is 672 ounces.
Step-by-step explanation:
If four kids drank 24 ounces of milk for seven days, you would solve it as follows:
First, the amount all the kids drink in one day combined is 96 ounces.
If they drink 96 per day, and they do so for a week (7 days), then that is 96 × 7 because its 96 seven times.
7 × 96 = 672

What are the solutions to the equation (2x – 5)(3x – 1) = 0?
x = 5/2 or x = 1/3
C is the answer.
Answer:
x = 5/2 or x = 1/3
Step-by-step explanation:
Simplify
( 2 x − 5 )( 3 x − 1 ) .
6 x 2 − 17 x + 5 = 0
Use the quadratic formula to find the solutions.
[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] or [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]
Substitute the values a = 6 , b = − 17 , and c = 5 into the quadratic formula and solve for x .
17 ±sqrt(-17)^2-4*(6*5)
_________________

Simplify.
x = 17 ± 13 /12
The final answer is the combination of both solutions.

sum of 12.5 and product of 36
I mean 2 variables add up to 12.5
and multiply to 12.5
(x+y)=12.5
X ×Y=36
What is value of x and y
Answer:
(4.5, 8) and (8, 4.5)
Step-by-step explanation:
Given the equations
(x+y)=12.5 ... 1
X ×Y=36 .... 2
From 2, Y = 36/X
Substitute into 1
x+ 36/x = 12.5
x^2 + 36 = 12.5x
x^2 - 12.5x + 36 = 0
10x^2 - 125x + 360 = 0
2x^2 - 25x + 72 = 0
Factorize
2x^2 - 16x - 9x + 72 = 0
2x(x-8)-9(x-8) = 0
2x-9 = 0 and x-8 = 0
x = 9/2 and x = 8
when x = 9/2
Y = 36/(9/2)
Y = 36 * 2/9
Y = 8
When x = 8
Y = 36/X
Y = 36/8
Y = 4.5
Hence the solutions are (4.5, 8) and (8, 4.5)

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $6500 to rent trucks plus an additional fee of 175.25 for each ton of sugar. The second company charges $5696 to rent trucks plus an additional fee of 225.50 for each ton of sugar.
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Answer:
14 tons
$3,860.50
Step-by-step explanation:
Let x = the amount of sugar transported.
First company:
The cost is $3157 truck rental plus $50.25 per ton of sugar.
Total cost = 3157 + 50.25x dollars
Second company:
There is no charge for truck rental, but it costs $275.75 per ton of sugar.
The total cost is
275.75x
When the two costs are the same, then
275.75x = 3157 +50.25x
225.5x = 3157
x = 14 tons
The total cost is 275.75*14 = $3,860.50

Answer:
the correct answer is
229/479 = 0.48
The probability that a randomly chosen person from this group is male is 0.48.
What is the probability that a male is chosen?Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
The probability of choosing a male = number of males / total number of males and females
229/479 = 0.48
