The data below shows the survey result of 75 randomly selected students.
The school has 1,138 students total. Based on the results of the poll, how many of the school's students should be expected to travel by car? Round your answer to the nearest whole number.
Show your work using the sketch board OR you may insert an image of your work on the following slide.
Chart relating to the question is attached below.
Answer:
349 students
Step-by-step explanation:
Based on the chart given, we can obtain the experimental probability or proportion for the travel plan of 75 students :
Proportion who would be traveling by car :
Number traveling By car / number of samples
p(car) = 23 / 75 = 0.30666
If total number of students = 1138
Using the proportion obtained from the sample, the number of students who would be traveling by car from the population would be :
= 0.30666 * 1138
= 348.98 students
= 349 students

Solve for x by factoring
Answer:
x = 5
Step-by-step explanation:
The area of the rectangle can be found by multiplying length x width:
Total Area = 55:
Length = x + 6
Width = x
Set the equation:
(x)(x + 6) = 55
First, distribute x to all terms within the parenthesis:
(x)(x + 6) = x² + 6x = 55
Next, set the equation equal to 0. Subtract 55 from both sides of the equation:
x² + 6x (-55) = 55 (-55)
x² + 6x - 55 = 0
Then, solve for x. Find factors of x² and -55 that, when combined, will result in 6x:
x² + 6x - 55 = 0
x 11
x -5
(x + 11)(x - 5) = 0
Then, solve each individual parenthesis:
(x + 11) = 0
x + 11 (-11) = 0 (-11)
x = -11
(x - 5) = 0
x - 5 (+5) = 0 (+5)
x = 5
Note, however, that a side cannot have a negative measurement. Therefore, x = 5 is your only answer.

If , what is the truncation error for S4?
Truncation error for S4 is 0.037.
What is Truncation Error?Truncation errors are defined as the errors formed when we use approximation instead of actual procedures.
Given is a series.
S4 means,
6/(3¹) + 6/(3²) + 6/(3³) + 6/(3⁴)
The actual sum of these values gives,
2 + 0.6666..7 + 0.2222.. + 0.074074...
= 2.962962..
≈ 2.963
Truncation error = 3 - 2.963 = 0.037
Hence the truncation error is 0.037.

Michelle has four white socks two black socks and two gray socks in her drawer she pulled that one sock on the drawer without looking she's not put it back then Michelle Pulls a second Sock from the drawer .what is the probability that Michelle pulls two white socks from the drawer a.3/14 b. 3/16 c. 1/16 d. 1/2
Answer:
3/14
Step-by-step explanation:
prob for the 1st sock=4/8=1/2
prob for the 2nd sock=3/7(there's 7 socks left now and only 3 were white since she pulled one out and didn't put it back)
so the prob of both being white is 1/2*3/7=3/14

The average rate of change on the interval from 0 to 10 is 30
How to determine the average rate of change?The function is given as:
f(x)=3x^2-8
The interval is given as:
0 to 10
Calculate f(0) and f(10)
f(0)=3 *(0)^2 -8
f(0) = -8
f(10)=3 *(10)^2 -8
f(10) = 292
The average rate of change is then calculated as:
Rate = (f(10) - f(0))/(10 - 0)
This gives
Rate = (292 +8 )/(10 - 0)
Evaluate
Rate = 30
Hence, the average rate of change on the interval from 0 to 10 is 30

P(graduate) = Total graduates / Total studentsP(graduate) = 2610/10730*100% = 24% (rounded)The probability that a student selected at random is a graduate student is 31%.
What is probability?The probability of an event happening is represented by a number. The ratio of favourable outcomes to all outcomes is how probability is defined.
The total number of students is 6101, out of which 1879 are graduate students. Therefore, the probability that a student selected at random is a graduate student is:
P(graduate student) = number of graduate students / total number of students
P = 1879 / 6101
P = 0.3078

4. The volume of a cylinder is 9.5 m cube, rounded to the nearest tenth of a cubic
meter. Which diagram shows the cylinder?
====================================================
Explanation:
You'll have to go through each answer choice one by one to check if those dimensions lead to to a volume of roughly 9.5 m^3
For choice A, we have a radius of 0.7/2 = 0.35 meters and a height of 6.2 meters. The volume of the cylinder is pi*r^2*h = 3.14*(0.35)^2*6.2 = 2.38483 which rounds to 2.4 cubic meters. We can rule out choice A because we want 9.5 as a result instead of 2.4
We follow the same steps for choices B through D. You should find that choice D is the answer because:
V = pi*r^2*h = 3.14*(1.4/2)^2*6.2 = 9.53932 which rounds to 9.5 m^3.
Note the 1.4/2 is dividing the diameter 1.4 in half to get the radius.

a rectangular computer screen has an area o A square inches. The width of the computer is 7 inches. Which equation rpresents x the length of the computer screen in inches
Answer:
x = A/7
Step-by-step explanation:
Given that the screen is rectangular, recall that the area A of a rectangle whose length is L and width is W is given as
A = L * W
Hence if the width is 7 inches and the length is x inches then the area which is A square inches is connected to both sides as
A = x * 7
Divide both sides by 7
x = A/7 inches
The sum of two consecutive odd numbers is 20 and their difference is 2. Find the two numbers
Answer:
9 and 11
Step-by-step explanation:
let the consecutive odd numbers be n and n + 2, then
n + n + 2 = 20
2n + 2 = 20 ( subtract 2 from both sides )
2n = 18 ( divide both sides by 2 )
n = 9 and n + 2 = 9 + 2 = 11
The 2 numbers are 9 and 11
