Answer:
2 students said only fall
Step-by-step explanation:
Given:
Total number of students = 25
Number of students who like fall season (F) = 12
Number of students who like summer season (S) = 18
Number of students who like both fall and summer season [tex]\left ( F\cap S \right )[/tex] = 10
To find:
Number of students who like only fall season
Solution:
A set is a well defined collection of objects. A universal set is the set of which all other sets are subsets. It is denoted by U.
According to the venn diagram,
n(only F) = [tex]=n(F)-n\left ( F\cap S \right )[/tex]
[tex]=12-10=2[/tex]
So, 2 students said only fall.
A coordinate plane. A line passes through the point (0, 1) and has a positive slope. Which of these points could that line NOT pass through? Check all that apply. (12, 3) (–2, –5) (–3, 1) (1, 15) (5, –2)
For a line with a positive slope that passes through (0, 1), the points that can't be on the line are:
(-3, 1) and (5, -2)
Which of these points could that line NOT pass through?We know that the line passes through the point (0, 1) and has a positive slope. This means that for values of x larger than x = 0, the values of y in the line will be larger than 1.
Then if we find a point with:
x > 0
y ≤ 1
That point clearly can't belong to our line.
And points with:
x < 0
y ≥ 1
Also can't belong to the line.
Then the correct options are: (-3, 1) and (5, -2)

Seth's family plans to drive 220 220 miles to their vacation spot. They would like to complete the drive in 4 4 hours. Find the average speed in miles per hour needed to make the trip in the desired time.
Answer: 55 miles per hour
Step-by-step explanation:
Here is the complete question:
Seth's family plans to drive 220 miles to their vacation spot. They would like to complete the drive in 4 hours.
Find the average speed in miles per hour needed to make the trip in the desired.
From the question, Seth's family plans to drive 220 miles to their vacation spot and they would like to complete the drive in 4 hours.
Average speed is calculated as distance travelled divided by the time taken. This will be:
Speed = Distance/Time
Average speed = 220/4
Average speed = 55 miles per hour
Jean-Paul Sovique, the famous sculptor, is building a solid conical sculpture. He has 1,178.1 cubic feet of clay to work with, and he wants his sculpture to be three times as high as its radius. What will the radius and height of his cone be?
Answer:
Radius = 7.21 feet.
Height = 21.63 feet
- to the nearest hundredth.
Step-by-step explanation:
Let the radius be r feet, then the height will be 3r feet.
So the volume = 1,178.1 = 1/3 π r^2 h
1.178.1 = 1/3 π r^2 3r
1/3 π 3 r^3 = 1178.1
π r^3 = 1178.1
r^3 = 1178.1/ π
r^3 = 375
r = 7.211 feet.
So the height = 3 * 7.211 ft
= 21.633 ft

An acorn falls from the branch of a tree to the ground 25 feet below. The distance, S, that the acorn is from the ground as it falls is represented by the equation S(t) = –16t2 + 25, where t is the number of seconds. For which interval of time is the acorn moving through the air?
Answer:
0<t<5/4 or B
edge
The interval of time, the acorn moving through the air is t > 5/4.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
An acorn falls from the branch of a tree to the ground below = 25 feet
The equation is [tex]S(t) = -16t^2 + 25[/tex], where t is the number of seconds and
S is the distance.
At t=0,
⇒ [tex]S(0) = -16(0)^2 + 25[/tex]
⇒ [tex]S(0) = 25[/tex]
Initially, the acron is at 25 feet above the ground level. So t > 0, for the acron to fly on air.
The interval can be found as,
⇒ [tex]-16t^2 + 25 > 0[/tex]
⇒ [tex]-16t^2 > -25[/tex]
⇒ [tex]t^2 > \frac{25}{16}[/tex]
⇒ [tex]t > \sqrt{\frac{25}{16} }[/tex]
⇒ [tex]t > \frac{5}{4} or \frac{-5}{4}[/tex]
since t > 0, the interval is [tex]t > \frac{5}{4}[/tex]
Hence we can conclude that the interval of time, the acorn moving through the air is t > 5/4.

The question is incomplete:
Noah pays $25.20 for non perishable food items to give to the local homeless shelter the price includes a 5% sales of tax. what is the price before tax of the food items?
Answer:
$24
Step-by-step explanation:
From the information you have that the price of items is $25.20 and it includes a 5% tax. From this, you can write the following:
x+0.05x=25.20
Then, you can isolate x to find the price before tax:
1.05x=25.20
x=25.20/1.05
x= 24
According to this, the price before tax of the food items is $24.

Answer:
x^4 +y+1
Step-by-step explanation:
The quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, -17) is [tex]-17(x-1)^{2}[/tex].
What is vertex form of a quadratic function?The vertex form of a quadratic function is [tex]f(x) = a(x-h)^{2} + k[/tex] where a, h, and k are constants and (h, k ) is the vertex of the graph of the function.
According to the given question we have
The graph has the vertex is (1, 0) and passes through (2, -17)
Since, the general form of a quadratic function in a vertex form is
[tex]y = a(x-h)^{2}+ k[/tex]
substitute, h = 1 and k = 0 in the above equation
⇒ [tex]y = a(x-1)^{2} +(0)^{2}...(i)[/tex]
Also, the graph passes through the point (2, -17)
⇒ [tex]-17 = a(2-1)^{2}[/tex]
⇒ -17 = a or a = -17
Substitute the value of a in equation (i).
⇒[tex]y = -17(x-1)^{2}[/tex]
Therefore, the quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, -17) is [tex]-17(x-1)^{2}[/tex].

Ana will spin the spinner. What is the probability that Ana's spin will land on yellow? If there are 2 Red Sections, 3 Blue Sections, 4 yellow Sections, 3 Black Sections.
Answer:
The probability is 1/3
Step-by-step explanation:
Here, we are interested in calculating the probability that the spinner will land on the yellow section.
Firstly, we need to calculate the total number of sections. That would be = 2 + 3 + 4 + 3 = 12 sections
Now, the probability that the spinner will land on the yellow section = number of yellow sections/total number of sections
There are four yellow sections
Thus, the probability of the spinner falling on a yellow section = 4/12 = 1/3
