Answer:
Correct mean = 32 grams
Correct Standard deviation = observed S.D = 2 grams
Step-by-step explanation:
We are told in the question above :
A scientist is weighing each of 30 fish. She obtains a mean of 30 g and a standard deviation of 2 g. After completing the weighing, she finds that the scale was misaligned and always under reported every weight by 2 g that is
The mean after correcting the error in the scale is :
= observed mean + 2g
= 30g + 2g = 32g
The standard deviation after correcting the error in the scale remains the same as the difference of 2g has no significant effect on the Standard deviation.
This standard deviation = 2g

Philip is 4 years older than his brother. The sum of their ages is 26. How old is Philip's brother?
Answer:
Phillips brother is 11.
Step-by-step explanation:
11 + 15 = 26
Let x be age of Philip's brother.
4 + x +x = 26
2x = 26 -2
2x = 22
x = 22/2
x = 11
Philip's brother is 11 years old

Javier rounded to the nearest half to estimate the product of 3 2/5 and -3 7/8. How do the estimate and the actual product compare Word problem
Answer:
Step-by-step explanation:
}−2x+2y=−4
{3x+3y=−18
find the solution to the systems of equations
Answer:
Answer=
x=(-2),y=(-4)
and in components form,
(-2,-4)
Step-by-step explanation:
equation1 (-2x+2y=-4)
equation2 (3x+3y=-18)
(times equation 1 by 3 and times equation 2 by 2, to make the y values equal to each other)
E1 (-6x+6y=-12)
E2 (6x+6y=-36)
(subtract both equations from each other)
-6x+6y=-12
-
6x+6y=-36
=(-12x=24)
so, x=24÷-12=-2
(then we sub the value of x into one of the equations- the new one or the old one)
3x+3y=-18
(3×-2)+3y=-18
3y=-18+6=-12
y=-12÷3=-4

Dosage 5 mL 7.5 mL 10 mL 12.5 mL 15 mL
a) Evaluate the data and find the rate of change from one age group to the next. Explain how you found the rate of change. (2 points)
Answer:
The rate of change would be 50
Step-by-step explanation:
The graph with weight is going by 12 in each so an example would be 24 and 36 is going by 12 like the graph. and the dosage is going by 2.5 an example would be 5 and 7.5 witch is going by 2.5
What is the distance between (1, -4) and (1, 18)?
O 2 units
O 5 units
19 units
22 units
Answer:
22 units is the correct answer
l
The distance between (1, -4) and (1, 18) is 22 .The correct option is 4
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
Substituting the values of the coordinates in the distance formula;
D = [tex]\sqrt{(1-1)^{2}+(18+4)^{2} }[/tex]
=[tex]\sqrt{(0)^{2} + (22)^{2} }[/tex]
= [tex]\sqrt[n]{484}[/tex]
= 22
So, 22 units is the right answer.

Which expression equals 24?
Answer:
Lots.
Step-by-step explanation:
12 + 12, 2 x 12, 48 divided 2, etc.
Lots of expressions make 24.
Answer:For this case we must find an expression equivalent to 24, including exponents. To do this, we decompose factor 24. By definition, factorial decomposition consists of writing a number as the multiplication of other numbers.
Then:
We have the "2" is written three times, then:
Answer:24 = 2 to the 3rd power x 3

Find the sum of the polynomials: (x2 + 4x + 5) + (3x – 3)
+2x6 + 4x5 + x4 + 11x3 + 2x2 + 4x + 4
Answer:
x^2+7x+2
Step-by-step explanation:
hi! you can only combine terms with the same power (exponent value).
if we stack this like a regular addition problem, it will be easier.
x^2 + 4x + 5
3x - 3
-----------------------
4x+3x is 7x, and 5+ (-3) is 2. we keep the x^2 the same.
therefore, the answer is x^2+7x+2
hope this helps!
I need help with rounding
Answer:
ok so say the number is 23 you would look at the 3 and ask yourself is the 3 greater or smaller than 5 if its 4 and under you keep the number the same and just add a zero which would make it 20 and if its 5 and over you would add 1 to the first number and put a 0 at the end making it 30.
