Step-by-step explanation:
(3x² + 4x - 1) - ? = x²
Therefore ? = (3x² + 4x - 1) - x² = 2x² + 4x - 1.
The polynomial that should be subtracted is 2x² + 4x - 1.
find the area of the figure
Answer:
[tex]A=190\ cm^2[/tex]
Step-by-step explanation:
The attached figure shows a parallelogram.
Base, [tex]b=15\dfrac{1}{5}\ yd=\dfrac{76}{5}\ yd[/tex]
Height, [tex]h=12\dfrac{1}{2}\ yd=\dfrac{25}{2}\ yd[/tex]
We need to find the area of the figure. The area of a parallelogram is given by :
[tex]A=b\times h\\\\A=\dfrac{76}{5}\times \dfrac{25}{2}\\\\A=190\ cm^2[/tex]
So, the area of the figure is [tex]190\ cm^2[/tex].

Problem 1
Answer: 6.7----------------
Work Shown:
The two points are [tex](x_1,y_1) = (1,-2)[/tex] and [tex](x_2,y_2) = (4,4)[/tex]
Apply the distance formula to get the following
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-4)^2 + (-2-4)^2}\\\\d = \sqrt{(-3)^2 + (-6)^2}\\\\d = \sqrt{9 + 36}\\\\d = \sqrt{45}\\\\d \approx 6.7082039\\\\d \approx 6.7\\\\[/tex]
The distance between the two endpoints is roughly 6.7 units. This is the same as saying the segment is roughly 6.7 units long.
======================================================
Problem 2
Answer: 3.6----------------
Work Shown:
We'll use the distance formula here as well.
This time we have the two points [tex](x_1,y_1) = (3,1)[/tex] and [tex](x_2,y_2) = (5,-2)[/tex]
The distance between them is...
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-5)^2 + (1-(-2))^2}\\\\d = \sqrt{(3-5)^2 + (1+2)^2}\\\\d = \sqrt{(-2)^2 + (3)^2}\\\\d = \sqrt{4 + 9}\\\\d = \sqrt{13}\\\\d \approx 3.6055513\\\\d \approx 3.6\\\\[/tex]
This distance is approximate.

Daily driving time (hours)
Which of the following is the closest estimate to the percentile for the driver with a daily driving time of 6
hours?
Answer: 8/14
Step-by-step explanation: make 8/14 into a percent and you have the answer for khan
The closest estimate to the percentile for the driver with a daily driving time of 6 hours is 57th if the dot plot shows the number of hours of daily driving time for 14 school bus drivers.
What is a percentile?A percentile is a score that relates one rating to the scores of the rest of the group. It represents the proportion of scores that a given score surpassed.
We have:
Total number of observations N = 14
Index for 6 = 8
Percentile for the observation:
P = (R/N)×100
P = (8/14)×100
P = 0.571×100
P = 57.14 or
P = 57th percentile
Thus, the closest estimate to the percentile for the driver with a daily driving time of 6 hours is 57th if the dot plot shows the number of hours of daily driving time for 14 school bus drivers.

do you want to make a sodium carbonate solution with a concentration of 2.5%. You have 50 mL of a 1% solution about how many milliliters of a 6% solution should you add
9514 1404 393
Answer:
21 3/7 mL ≈ 21.43 mL
Step-by-step explanation:
Let x represent the amount of 6% solution that should be added. The the total volume of sodium carbonate in the mix is ...
1%(50) +6%(x) = 2.5%(50 +x)
50 +6x = 125 +2.5x . . . . . multiply by 100, eliminate parentheses
3.5x = 75 . . . . . . . . . . . . . subtract 2.5x+50
x = 21 3/7 . . . . . . . . . . . . . divide by 3.5
21 3/7 mL, about 21.43 mL, of 6% solution should be added to make a 2.5% solution.

a) Work out an estimate for the mean time it took the students.
Round your answer to 2 significant figures.
b) What fraction of the students finished in less than 20 minutes?
Answer:
a) The mean time it took the students, t ≈ 17.08 minutes
b) The fraction of the students that finished under 20 minutes is 2/3 of the students
Step-by-step explanation:
a) The mean of the frequency of grouped data is given as follows;
The given data arranged in tabular form is presented as follows;
[tex]\begin{array}{cccc}Time \, (t) \, in \, minutes & Midpoint, m & Frequency, f & Product \ m \cdot f \\5\leq t < 10 & 7.5 & 2 & 15 \\10\leq t < 15 & 12.5 & 9 & 112.5\\15\leq t < 20 & 17.5 & 5 & 87.5 \\20\leq t < 25 & 22.5 & 5 & 112.5 \\25 \leq t < 30 & 27.5 & 3 & 82.5 \\Sum & 87.5 & N = 24 & \Sigma (m\cdot f) = 410 \end{array}[/tex]
Therefore, the mean time it took the students = ∑(f·m)/N = 410/24 = [tex]17\frac{1}{12}[/tex]
The mean time it took the students, t ≈ 17.08 minutes
b) The number of the students that finished under 20 minutes = 2 + 9 + 5 = 16 students
The fraction of the students that finished under 20 minutes = 16/24 of the = 2/3 of the students.

a recent poll found that 76% of a random sample of 100 American movie-goers thought the popcorn sold at the movie theatre was overpriced
Do you think that the percentage of all American movie-goers we think the popcorn is overpriced is equal to 70%? Explain
Answer:
Yes, roughly 70%
Step-by-step explanation:
I would say that the percentage of all American movie-goers that think this would be around the 70% mark. This is based on the recent poll findings. That is because the poll inquiry was done on 100 randomly selected American movie-goers. Therefore, since it is a random selection from the same population then that makes it directly proportional to the overall population, this is assuming that the overall population is the same (American movie-goers)

If there are 68 people in a survey (everyone is either an adult or kid) and 60% are kids, how many adults are there?
Answer:
about 27 adults
Step-by-step explanation:
68 x 60% would find you kids
100% is 68, so, 100 - 60 = 40%
The remaining 40% are adults.
68 x 0.4 = 27.2
about 27.2 adults
Answer:
27 adults (rounded)
27.2 (not rounded)
Step-by-step explanation:
60% of 68 is 40.8
68 - 40.8 = 27.2
since .8 is bigger than .2 , 40.8 will be 41 and 27.2 will be 27
41 kids

Answer:
15% of 95-14.25
3 1/2% of 100-3.5
Step-by-step explanation:
Answer:
15% of 95= 14.25
3 1/2% of 100= 3.5
Step-by-step explanation:
3 1/2% of 100= 3.5, because 1% of 100=1
15% of 95=14.25 because 10% = 9.5 and 5% of 95=4.75
4.75+9.5= 14.25
