What is the mean median mode and range of the numbers 31 28 30 31 30 ...?
Answers
2. The median is the middle number in the list of numbers, so, the answer is 30 as well.
3. Mode is the number that appears most often, so here it is 30 and 31 because they both appear 2 times.
4. Range is the difference between the largest and smallest number, so 31 - 28 = 3.

If A is uniformly distributed over [-12,16] , what is the probability that the roots of the equation
x^2+Ax+A+3=0
are both real?
Answers
Final answer:
The probability that the roots of the equation [tex]x^2+Ax+A+3=0[/tex] are both real is approximately 0.6786. Then we calculate the length of the range [-3, 16] divided by the length of the entire interval [-12, 16].
Explanation:
To find the probability that the roots of the equation [tex]x^2+Ax+A+3=0[/tex] are both real, we need to determine the range of values for A that will result in real roots. For real roots, the discriminant (b^2-4ac) must be greater than or equal to 0. In this case, the equation can be rewritten as [tex]x^2+(1+A)x+(A+3)=0[/tex], so a = 1, b = (1+A), and c = (A+3). The discriminant is (1+A)^2 - 4(A+3), which must be greater than or equal to 0.
Expanding and simplifying, we get (A^2 + 2A + 1) - 4A - 12 ≥ 0. Combining like terms, we have [tex]A^2 - 2A - 11 > 0[/tex].
To solve the inequality, we can find the values of A that make the equation equal to 0. Factoring, we get (A - 4)(A + 3) ≥ 0. The solutions are A ≤ -3 or A ≥ 4.
Therefore, the probability that the roots of the equation are both real is the probability of A taking values in the interval [-12, -3] or [4, 16]. To find this probability, we divide the length of the interval [-3, 16] by the length of the entire interval [-12, 16].
P(A is in [-3, 16]) = (16 - (-3)) / (16 - (-12)) = 19 / 28 ≈ 0.6786.

eremy is working at 2 jobs to save money for his college education. He makes $8 per hours working for his uncle at Pizza Pie busing tables and $10 per hour tutoring peers after school in math. His goal is to make $160 per week. Part c- After researching the costs of colleges, Jeremy decides he needs to make more than $160 each week. Write an inequality in two variables to represent the amount of money Jeremy needs to make. Then graph.
Answers
Final answer:
Jeremy needs to create an inequality to represent his new earning goal higher than $160 a week, leading to the inequality 8x + 10y > 160. This can be graphed by first converting to intercept form, plotting the intercept and slope, drawing a dashed boundary line, and shading the region above this line.
Explanation:
Jeremy is working two jobs to save for his college education and needs to create an inequality to represent the amount he needs to make each week, now more than $160. Let's denote the number of hours Jeremy works busing tables as x and the number of hours he spends tutoring as y. He makes $8 per hour busing tables and $10 per hour tutoring.
To express Jeremy's goal of making more than $160 a week, we can write the following inequality:
8x + 10y > 160
To graph this inequality:
First, rewrite the inequality as y > (-4/5)x + 16 to get the intercept form.
Plot the y-intercept at (0, 16) on the graph.
Use the slope of -4/5 to determine another point. From (0, 16), move 5 units to the right (positive x-direction) and 4 units down (negative y-direction), then plot this second point.
Draw a dashed line through the two points to represent the boundary of the inequality (dashed because the inequality is strict and does not include the line itself).
Shade above the line to indicate that all solutions to the inequality lie in this area, where Jeremy would be earning more than $160.

Sq root of 2^2 = ?
Well 2 ^2 = 2•2 = 4 and the square root of 4 is 2. So whenever you think of what the opposite of squaring or raising something to the value of 2, the reverse would be taking the square root of the number or expression.
So sq root of 14x • sq. root of 14x = (sq. root of 14x) ^2 which is simply 14x.
The solution is 14x.

B: F(n) = 4+3n
C: F(n) = 3+4n
D: F(n) = 3+4(n-1)******
Answers
Answer:
1. 13, 17 Option D
2. -2 Option B
3. 2 Option C
4. F(n) = 3+4(n-1) Option D
Step-by-step explanation:
1.
Given sequence is: 1, 5, 9....
Common difference = 5-1 = 9-5 = 4
Next term is :
9+4 = 13
and
13+4= 17
So, next two terms are: 13 & 17.
2.
Given sequence is :
102, 100, 98, 96....
Common difference = 100 - 102 = 98 -100 = 96 - 98 = -2
3.
Given rule is :
Aₙ = -14 + (n - 1)(2)
Find the 9th term
so, we put n = 9
A₉ = -14 + (9-1)*2
A₉ = -14 + 8*2 = -14 + 16
A₉ = 2
Ninth term is 2.
4.
Given sequence is:
3, 7, 11, 15.....
Write the nth term
Formula is :
F(n) = a₁ + (n-1)d
Where a₁ is first term
n is number of terms
d is common difference
a₁ = 3
d = 7-3 = 11-7 = 15 - 11 = 4
So nth term is :
F(n) = 3 + 4(n-1)
That's the final answer.
Answer:

What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Use the Pythagorean theorem to calculate the length of AB as below,
OB² = AB² + OA²
(BC + OC)² = AB² + OA²
(27 + 24)² = AB² + 24²
AB² = 51² - 24²
AB = 45 units
Therefore, the correct option is A. The value of length AB is 45.

Deshaun went for a drive in his new car. He drove at a speed of 62 miles per hour for 99.2 miles. For how many hours did he drive?
Answers
99.2/62 = x
The answer is 1.6 hours.
Deshaun drove at a speed of 62 miles per hour for 99.2 miles. To calculate the time spent driving, use the formula Time = Distance / Speed. The time taken for his drive is approximately 1.6 hours.
The question pertains to calculating the driving time given the speed and distance traveled by Deshaun in his new car. He drove at a speed of 62 miles per hour for 99.2 miles. To find out how many hours he drove, we use the formula for time which is:
Time (t) = Distance (d) / Speed (v)Here, the distance d is 99.2 miles and the speed v is 62 miles per hour.
So we calculate the time t as follows:
t = 99.2 miles / 62 miles per hourThe time taken by Deshaun for his drive is approximately 1.6 hours.
