Determine whether the given ordered pair is a solution of the system.
(2,-1)
7x + 2y = 12
6x - 3y = 20
Answer:
Not a solution of the system
Step-by-step explanation:
Substitute 2 for x and -1 for y
[tex]7(2)+2(-1)=12\\6(2)-3(-1)=20[/tex]
Simplify
[tex]14-2=12\\12+3=20[/tex]
Simplify
[tex]12=12\\15\neq 20[/tex]
F(x) = x^3 (a) computer f(x)dx (b) computer the approximation L, and T, for n=4, 8, and 16 for the integral in part (a). For each of these, compute the corresponding absolute error.
Answer and Step-by-step explanation:
F(x) = x^3 (a)
then
compute f(x) dx for each of these, compute the corresponding absolute error.
Solution: f(x) = x3
F(x) d(x) = 3x2
The absolute error are ∆x= |x-ẋ|, ∆f=|f(x) – f(ẋ)|
(b) Compute the approximation L, and T, for n=4, 8, and 16 for an integral part.
The linear (L) approximation of function f(x) = x3, n= 4
f(4) = (4)3 = 64 and f”(4) = 3(4)2 = 48
The linear approximation is L4(x) = f (4) + f’(4)(x-4)
= 64 + 48 (x-4)
For n= 8,
f(8) = 512 and f,(8)= 3(8)2= 192
The linear approximate is L8(x) = f(8) + f’(8)(x-8)
Similarly for n= 16 the linear approximate is L16(x) = f (16) + f (16) (x-16)
The approximation for T, trapezoidal rule is:
a ʃb f(x)dx = Tn
for n = 4 the T approximation is:
T4 =a ʃb x3 dx
For n= 8 :
T8 = a ʃb x3 dx
For n= 16 : T16= a ʃb x3 dx.
Sara's grades are 78, 72, 66, 80, and 84. Sara decides to study hard for the final. Her score is 100. As an outlier, how does
100 affect the mean of Sara's previous scores? Assume all scores are treated equally.
A)
The outlier did not affect the mean.
B)
The outlier raised the mean by 4 points.
C)
The outlier lowered the mean by 2 points.
D)
The outlier raised the mean by 2 points.
Answer:
B
Step-by-step explanation:
The Mean(Average) of 78+72+66+80+84 is 76 because (78+72+66+80+84)/5* and (78+72+66+80+84+100)/6* is 80.
*You get this number by counting the number of numbers you entered (78+72+66+80+84) there are 5 numbers.

Step-by-step explanation:
Gavin, Colin and Dan share some sweets in the ratio 2:4:3. Gavin gets 24 sweets
How many more sweets does Colin get over Dan?
Answer:
12
Step-by-step explanation:
[tex]G:C:D\\----\\2:4:3[/tex]
Gavin has 24 sweets which is 2 units.
2 units = 24 sweets
1 unit = [tex]24\ sweets \div 2 = 12\ sweets[/tex]
Colin has 4 units, while Dan has 3 units.
Colin has 1 unit more than Dan.
Since 1 unit is 12 sweets, Colin has 12 more sweets than Dan.
What is the mean what is the mean for 35, 40, 12, 16, 25, 10
Answer:
Mean=23Step-by-step explanation:
Mean = Sum of all values/ total no of values
There are six numbers .
Mean =
[tex]\frac{35+40+12+16+25+10}{6} \\\\= \frac{138}{6} \\\\=23[/tex]
Answer:
[tex]\boxed {\tt 23}[/tex]
Step-by-step explanation:
The mean can be found by adding all the values together and dividing by the number of values.
1. Add the values
The values are: 35, 40, 12, 16, 25, 10 Add them: 35+40+12+16+25+10=1382. Divide by the number of values
Count how many numbers are in the set of data. There are 6 values. Divide 138 by 6.
138/6=23The mean of the data set is 23.

Answer: Where's B?
Step-by-step explanation:
Classify the two given samples as independent or dependent.Sample 1:The gas mileage for 48 trucksThe gas mileage for 48 trucks nothingSample 2:The gas mileage for the same 48 trucks after receiving a tuneupThe gas mileage for the same 48 trucks after receiving a tuneup nothingChoose the correct answer below.A.The two given samples are independent because different vehicles were sampled.B.The two given samples are dependent because the same vehicles were sampled.C.The two given samples are independent because the same vehicles were sampled.D.The two given samples are dependent because different vehicles were sampled.
Answer:
Option B
Step-by-step explanation:
The two samples are paired as the gas mileage of 48 trucks is measured for before tuneup and after tuneup. The gas mileage of 48 trucks will be affected by receiving tuneup. As the same 48 trucks are selected for tuneup, so the sample will be dependent. Hence the two samples are dependent because the same trucks are sampled.

The acceleration of an object varies directly with the force acting on it. If a force of 70 newtons (N) causes an acceleration of 6.5 m/s2, what force will cause an acceleration of 8 m/s2? Round your answer to the hundredths place.
0.74 N
0.743 N
86.15 N
86.158 N
Answer:
86.15N
Step-by-step explanation:

Answer:
The answer would be C
Step-by-step explanation:
778 is greater than 750, therefore the estimate for that would be 800. Then for 23, it is less 25 therefore, 23 would estimate to 20

How do you do this question?
Step-by-step explanation:
f(x) = 38 cos(x²)
Use chain rule to take the derivative.
f'(x) = -38 sin(x²) (2x)
f'(x) = -76x sin(x²)
Use product rule and chain rule to take the derivative.
f"(x) = -76x cos(x²) (2x) + (-76) sin(x²)
f"(x) = -152x² cos(x²) − 76 sin(x²)

What is rounding for math
Answer:
Step-by-step explanation:
Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. But 76 goes up to 80. There are many ways to round.
Hey there!
Rounding is estimating a number to its closest value. Let's say for example the number 226. If you round 226 to the nearest ten, you would get 230. This is what rounding is.
Hope this helps!

What is the midpoint of a segment with endpoints at(-4,-8) and (8, 10)?
Answer:
The answer is
( 2 , 1)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-4,-8) and (8, 10)
The midpoint is
[tex]M = ( \frac{ - 4 + 8}{2} , \: \frac{ - 8 + 10}{2} ) \\ = ( \frac{4}{2} , \frac{2}{2} )[/tex]
We have the final answer as
( 2 , 1)Hope this helps you
