Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating rectangle.
2x + y^2 = 48, x = y
Answer:
Attached please find response.
Step-by-step explanation:
We wish to find the area between the curves 2x+y2=8 and y=x.
Substituting y for x in the equation 2x+y2=8 yields
2y+y2y2+2y−8(y+4)(y−2)=8=0=0
so the line y=x intersects the parabola 2x+y2=8 at the points (−4,−4) and (2,2). Solving the equation 2x+y2=8 for x yields
x=4−12y2
From sketching the graphs of the parabola and the line, we see that the x-values on the parabola are at least those on the line when −4≤y≤2.
In this exercise we have to use the function informed to identify the value of the formed figure, then:
[tex]x=4-12y^2[/tex]
Given the following information in the exercise statement:
[tex]2x+y^2=8[/tex] [tex]y=x[/tex]Substituting y for x in the equation:
[tex]2y+y^2\\y^2+2y-8(y+4)(y-2)=8[/tex]
Analyzing the equation formed, we can see that it will have the shape of a parabola, and that the values of x will be between:
[tex]X: -4\leq y\leq 2[/tex]

Pls solve it and show your work :((
Answer:
See below
Step-by-step explanation:
To graph the line we need two points, one point is the y-intercept, the second point to be calculated.
Q7
y = -3x + 6
The y-intercept is (0, 6)Let the domain be x = 5 for the second point, then:
y = -3*5 + 6 = -15 + 6 = -9The point is (5, -9)Connect these points to get the graph
Q8
y = 4/5x - 3
The y-intercept is (0, -3)Let the domain be x = 5 for the second point, then:
y = 4/5*5 - 3 = 4 - 3 = 1The point is (5, 1)Connect these two points to get the graph

The following are the number of sales which a sample of 9 car salespeople of an insurance company in Florida and a sample of 8 salespeople in Washington made over a certain year. Florida: 39, 44, 42, 50, 55, 48, 51, 38, 54 Washington: 42, 43, 56, 50, 49, 52, 53, 56 Assuming that the populations sampled can be approximated closely with normal distributions having the same variance, is there a difference in the number of sales between the Florida salespeople and the Washington salespeople?
Find s^2p (round off to the nearest integer)
Answer:
There is no difference in the number of sales between The Florida salespeople and Washington salespeople
Sp^2 = 39
Step-by-step explanation:
Given data :
Florida: 39, 44, 42, 50, 55, 48, 51, 38, 54
Washington: 42, 43, 56, 50, 49, 52, 53, 56
number of sales persons in Florida = 9
number of sales persons in Washington = 8
variance = constant
a)Determine if there is difference between the Florida salespeople and Washington salespeople
we will carry out a two tailed test based on the given data
H0 : u1 = u2
H1 : u1 ≠ u2
x ( mean ) = 46.77, y ( mean ) = 50.13 ,
s1^2 = 39.69, s2^2 = 28.41, n1 = 9 , n2 = 8
therefore :
Sp^2 = [tex]\frac{n1s1^2 + n2s2^2}{n1 + n2-2}[/tex] = 38.96 ≈ 39
performing test statistic
t = [tex]\frac{x- y }{sp\sqrt{\frac{1}{n1} +\frac{1}{n2} } }[/tex] = [tex]\frac{-3.36}{3.0330}[/tex] = -1.1078
critical value is at t = 0.05 and for a two tailed test it is at 2.13 therefore e accept H0 at 5% . This shows that there is no difference in sales

x = 4 - 3x
2x = 4
Answer:
no
x = 4 - 3x x = 1
2x = 4 x =2

Answer:
No. They are not equivalent. The first one would end up being x=1, while the second one would be x=2.

what theorem can be used to probe the 2 triangles similar?
Answer:
B. SAS
Step-by-step explanation:
Two sides of ∆DEF (DE and DF) are proportional to two corresponding sides of ∆ABC (AB and AC), and also their included angles (<D and <A) are equal to each other.
Therefore, based on the SAS criterion, both triangles are proven to be similar to each other.
Both triangles satisfy the SAD Criterion, and hence, they can be proven to be similar to each other.

Scatter plotsGiven the ordered pairs that Samantha needs to plot given as shown;
(19,9) , (8,6) , (10,14) and (4,15)From the given ordered pair, we can see that the outlier is (8, 6) because it lies an abnormal distance from other coordinate points.
We can see that as the x-values is increasing, the y-values is decreasing. Hence the ordered pairs that she still needs to plot are the remaining coordinate order than the outlier.

harmony places the letters of December into a bag. a letter will be randomly selected and not replaced. then the other letter will be selected. what is the probability of harmony selecting a C and then E?
Answer:
1/56
Total letters are 8
probability of first selecting c is 1/8 and since it's not replaced, probability of selecting e is 1/7
Total probability= 1/8*1/7=1/56
Therefore, total probability is 1/56

184. A student estimated a mass to be 40 g. After carefully measuring, she
found the actual mass to be 45 g. What is the percent of error?
Answer:
[tex]\boxed {\boxed {\sf About \ 11 \%}}[/tex]
Step-by-step explanation:
The formula for percent error is:
[tex]\% \ error = | \frac{measured \ value - actual \ value }{actual \ value} | *100[/tex]
For this, the measured value is the estimation of 40 grams. The actual value is the true mass of 45 grams.
[tex]measured = 40 \ g \\actual = 45 \ g[/tex]
[tex]\% \ error = | \frac{40 \ g - 45 \ g }{45 \ g } | *100[/tex]
Solve the numerator.
40 grams - 45 grams = -5 grams[tex]\% \ error = | \frac{-5 \ g }{45 \ g } | *100[/tex]
Divide.
[tex]\% \ error = | \frac{-5 \ g }{45 \ g } | *100[/tex]
[tex]\% \ error = | -0.111111111| *100[/tex]
[tex]\% \ error = 0.111111111*100\\\% \ error = 11.11111 \\\% \ error \approx 11[/tex]
The percent error is about 11%

Answer:
0.606928 or 0.61 rounded to the nearest hundredth
Step-by-step explanation:
it is a cube so all sides are equal:
Volume= a^3
V=(1/3)^3
V=1/27 in^3
convert in^3 to cm^3
1 in^3 16.3871 cm^3
1/27 in^3 ????
[1/27(16.3871)]/1 = 0.606928 or 0.61 rounded to the nearest hundredth
Researchers want to investigate if students retain more information if it printed on blue paper rather than white paper. They recruit 100 elementary students, 100 middle school students, and 100 high school students to participate. The researchers then randomly assigned half of the elementary students, half of the middle school students, and half of the high school students to receive the information on blue paper. The remaining students receive the same information on white paper.

Stratified design with color of paper as the blocks
Step-by-step explanation:
The experimental design that this question uses is the stratified design with color of paper as the blocks
A stratified design is one where the population has been divided into strata that are homogeneous. A good number of participants would then be picked for each of the stratum. The homogeneous strata are also known as the blocks and here in this question we have color of paper as the block here.
The students are of different school levels, elementary, high school and middle school. Each of these levels have 100 students. The students in each levels are halved and each half is randomly assigned information on either a white paper or a blue paper.

Stratified sampling refers to a type of sampling method . With stratified sampling, the researcher divides the population into separate groups, called strata. Then, a probability sample (often a simple random sample ) is drawn from each group. Stratified sampling has several advantages over simple random sampling.The homogeneous strata are also known as the blocks and here in this question we have color of paper as the block here. The students are of different school levels, elementary, high school and middle school. Each of these levels have 100 students.
