The high temperatures for the last seven days are: High Temperatures: 81, 78, 83, 89, 80, 87, 78
Find the MEAN of the temperatures. Round to the nearest tenths place.
A. 82.3
B. 89
C. 83
D. 78
Answer:
Mean of temperatures = 82.3 (Approx.)
Step-by-step explanation:
Given:
Number of days = 7 days
Temperatures in 7 days = 81, 78, 83, 89, 80, 87, 78
Find;
Mean of temperatures
Computation:
Mean = Sum of all observation / Number of observation
Mean of temperatures = Sum of all seven days temperature / Number of days
Mean of temperatures = [81 + 78 + 83 + 89 + 80 + 87 + 78] / 7
Mean of temperatures = 576 / 7
Mean of temperatures = 82.2857
Mean of temperatures = 82.3 (Approx.)
A number from 13 to 21 is drawn at random.
P( a prime number)
Answer:
Probability[Prime number] = 1/3
Step-by-step explanation:
Given:
Total number between 13 to 21;
13, 14, 15, 16, 17, 18, 19, 20, 21
Find:
Probability[Prime number]
Computation;
Total number between 13 to 21 = 9
Total number of prime number;
13, 17 ,19
Total number of prime number = 3
Probability pf event = Number of favorable output / Total output
Probability[Prime number] = Total number of prime number / Total number between 13 to 21
Probability[Prime number] = 3 / 9
Probability[Prime number] = 1/3
On a basketball court there is a semicircle above the free throw line that has a radius of 7 find the area of semicircle
Answer: [tex]77\ \text{sq. units}[/tex]
Step-by-step explanation:
Given
The radius of the semi-circle is [tex]r=7[/tex]
We know, area of the circle is [tex]\pi r^2[/tex]
So, the area of the semi-circle is half of it i.e. [tex]\frac{1}{2}\pi r^2[/tex]
Put the value
[tex]\Rightarrow \dfrac{1}{2}\times\pi \times 7^2=76.97\\\Rightarrow \approx 77\ \text{sq. units}[/tex]
The area of the semi-circle is [tex]77\ \text{sq. units}[/tex]
The area of a rectangular fountain is x2 + 12x + 20 square feet. A 5-foot walkway is built around the
fountain. Find the dimensions of the outside border of the walkway.
Answer:
x + 7 ft and x + 15 ft as the dimensions of the outside border of the walkway.
Step-by-step explanation:
[tex]x^{2} +12x + 20 = (x + 2)(x + 10)[/tex]
The dimensions of the fountain is x + 2 and x + 10
Adding the 5-ft walkway, we get x + 7 ft and x + 15 ft as the dimensions of the outside border of the walkway.
Andy’s goal for the week is to run 19 miles. he ran 6.19 miles between monday and friday. he ran 3.1 miles on saturday. how many more miles should he run on sunday to meet his goal?
Answer:
9.71 miles
Step-by-step explanation:
total miles he ran = 6.19 + 3.1 = 9.29
Target = 19 miles
Goal for sunday = 19 - 9.29 = 9.71

In the diagram, y= x-15 and z=125. What is the value of x?
Answer:
x = 70
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is ab exterior angle of the triangle , then
x + y = z , that is
x + x - 15 = 125
2x - 15 = 125 ( add 15 to both sides )
2x = 140 ( divide both sides by 2 )
x = 70
Solve for x..................
Answer:
x = 4
Step-by-step explanation:
(5x+131)° and (5x+19)° are supplementary. Therefore, (5x+19)° + (5x+131)° equals to 180°.
Knowing that, we can do the following:
(5x+19) + (5x+131) = 1805x + 19 + 5x + 131 = 18010x + 140 = 18010x = 40x = 4Please help! I need the work for this.

25. A sequence of positive integers with 2020 terms is called an FT sequence if each term
after the second is the sum of the previous two terms. For example, if the first two
terms of an FT sequence are 8 and 7, the sequence would begin 8,7,15,22,37,....
For some positive integer m, there are exactly 2415 FT sequences where the first two
terms are each less than 2m and the number of odd-valued terms is more than twice
the number of even-valued terms. What is the value of m?
(A) 21
(B) 69 (C) 115 (D) 35 (E) 105
Answer:
The first term in the sequence is odd-valued and so there are m choices for it.2020 Gauss Contest Solutions Page 19
The second term in the sequence is even-valued and so there are m − 1 choices for it.
Thus, there are a total of m × (m − 1) FT sequences that begin with an odd-valued term
followed by an even-valued term.
Finally, we consider the FT sequences that begin with an even-valued term followed by an
odd-valued term (Parity #4).
Again, there are exactly twice as many odd-valued terms as there are even-valued terms in the
first 2019 terms (since the pattern repeats even, odd, odd).
However in this case, the 2020th term is even and so there are fewer than twice as many odd valued terms as there are even-valued terms.
Thus, there are m2 + m × (m − 1) FT sequences that satisfy the required conditions.
Since there are 2415 such FT sequences, we may solve m2 + m × (m − 1) = 2415 by trial and
error.
Evaluating m2 + m × (m − 1) when m = 30, we get 302 + 30 × 29 = 1770, and so m is greater
than 30.
When m = 33, we get 332 + 33 × 32 = 2145.
When m = 34, we get 342 + 34 × 33 = 2278.
When m = 35, we get 352 + 35 × 34 = 2415, as required.

Answer:
80 cm²
Step-by-step explanation:
Given 2 similar figures with sides in the ratio a : b , then
ratio of areas = a² : b²
Here ratio of sides = 7 : 14 = 1 : 2
ratio of areas = 1² : 2² = 1 : 4
Thus area of B is 4 times area of A
area of B = 4 × 20 = 80 cm²

Find the value of X...................................................................
Answer and Step-by-step explanation:
To find the value of x, we must add together the two angles, and equal it to 180.
7x + x + 20 = 180
8x + 20 = 180
Subtract 20 from both sides.
8x = 160
Now divide each side by 8.
x = 20
We get the result to be 20 = x.

The school that Shawna goes to is selling tickets to a spring musical. On the first day of ticke sales the school sold 7 adult tickets and 7 student tickets for a total of $91. The school took ir $170 on the second day by selling 14 adult tickets and 12 student tickets. Find the price of an adult ticket and the price of a student ticket.
Answer:
x = price of adult tickets = $7
y = price of students tickets = $6
Step-by-step explanation:
Let
x = price of adult tickets
y = price of students tickets
7x + 7y = 91 (1)
14x + 12y = 170 (2)
Multiply (1) by 2 to
14x + 14y = 182 (3)
14x + 12y = 170 (2)
Subtract (2) from (3) to eliminate x
14y - 12y = 182 - 170
2y = 12
y = 12/2
y = 6
Substitute y = 6 into (1)
7x + 7y = 91 (1)
7x + 7(6) = 91
7x + 42 = 91
7x = 91 - 42
7x = 49
x = 49/7
x = 7
x = price of adult tickets = $7
y = price of students tickets = $6

How do I do this problem
Answer:
The Ross family used it for 15 hours
The Watson family used it for 20 hours
Step-by-step explanation:
We can rewrite this word problem using variables.
[tex](x*40)+(y*20)=1000[/tex] and [tex]x+y=35[/tex]
Now we can split 35 between x and y. Since 35 can't be split into a whole number, I have split it into 17 and 18
(17*40) + (18*20) = 1040
This is close but 40 too much. Since this is 40 off, we need to move 2 more hours to the Watson family.
(15*40) + (20*20) = 1000
This means -
The Ross family used it for 15 hours
The Watson family used it for 20 hours

At a football stadium, 10% of the fans in attendance were teenagers. If there were 100 teenagers at the football stadium, what was the total number of people at the stadium?
Answer:
The answer is 1000.
*Explanation*
Attendance at the football stadium is 100%
100% - 10% = 90%
10% = 100 attendance
900% = 900 attendance
900 + 100 = 1000 attendance
