John has on his shelf four books of poetry, four novels, and two reference works. suppose from these ten books, we were to pick two books at random. what is the probability that we pick one novel and one reference work? (a) 1/2
The probability isf 8/45.
Probability calculation:
Calculate the total number of ways to pick 2 books from the 10 books, which is 10 choose 2 = 45.
Calculate the number of ways to pick 1 novel and 1 reference work, which is 4 choose 1 for novels * 2 choose 1 for reference works = 8.
Divide the number of favorable outcomes by the total outcomes to get the probability: 8/45 = 8/45.
How much money should a student place in a time deposit in a bank that pays 1.1% compounded annually so that he will have Php 200,000.00 after 6 yrs?
Let us say that:
P = present value
F = future value
i = interest rate
n = period
P = F / [ (1 + i ) ^n ]
P = 200000 / [ (1 + 0.011) ^6 ]
P = 187293.65
Therefore the student must put up Php 187,293.65

Which of the following is the linear parent function
Answer:
Option C is correct linear parent function.
Step-by-step explanation:
We need to choose from the option as a linear parent function.
We will look each option and explain each one.
Option A: [tex]f(x)=|x|[/tex]
Here we have absolute sign on x. It is parent function of absolute function.
Option B: [tex]f(x)=x^2[/tex]
Here we have square on x. It is parent function of quadratic or parabola.
Option C: [tex]f(x)=x[/tex]
It is parent function of linear because exponent of x is 1 and coefficient of x is 1.
Option D: [tex]f(x)=2x[/tex]
It is linear function but not parent because coefficient of x is not 1.
Hence, Option C is correct linear parent function.

If 1 inch = 2.5 centimeters, how many centimeters are there in 40 inches
Final answer:
To convert 40 inches to centimeters, multiply the number of inches (40) by the conversion factor (2.54 cm/inch), which equals 101.6 centimeters.
Explanation:
To calculate how many centimeters are in 40 inches, we use the conversion factor that 1 inch is exactly equal to 2.54 centimeters. Knowing this, we can simply multiply the number of inches by the conversion factor to get the measurement in centimeters.
Determine the number of inches to be converted (in this case, 40 inches).
Multiply the number of inches by the conversion factor (2.54 cm for every 1 inch).
Calculation: 40 inches × 2.54 cm/inch = 101.6 centimeters.
Therefore, there are 101.6 centimeters in 40 inches.
There are 15 tennis balls in a box, of which 9 have not previously been used. three of the balls are randomly chosen, played with, and then returned to the box. later, another 3 balls are randomly chosen from the box. find the probability that none of these balls has ever been used
Final answer:
The probability that none of the balls have been previously used is 20.96%.
Explanation:
To find the probability that none of the three balls selected have ever been used, we first calculate the probability of selecting a ball that has not been used each time.
Initially, there are 15 balls in total, out of which 9 have not been used. So, the probability of selecting a ball that has not been used on the first draw is 9/15.
After the first draw, the number of balls in the box remains the same, but the number of unused balls decreases to 8. So, the probability of selecting a ball that has not been used on the second draw is 8/15.
Similarly, for the third draw, the probability of selecting a ball that has not been used is 7/15.
Since the balls are chosen randomly and returned to the box after each draw, the probabilities are independent. Therefore, to find the probability that none of the balls have ever been used, we multiply the probabilities of each draw:
(9/15) x (8/15) x (7/15) = 0.2096, or approximately 20.96%.

You arrive in my class 45 seconds after leaving math which is 90 meters away
You traveled the 90 meters in 45 seconds at a speed of 2 meters per second.
Speed = Distance / Time
Given:
Distance = 90 metersTime = 45 secondsWe can now calculate the speed:
Speed = 90 meters / 45 seconds
= 2 meters/second
This means you traveled at a speed of 2 meters per second to get from your math class to the next class.
Complete Question:

△ABC is mapped to △A′B′C′ using each of the given rules.
Which rules would result in △ABC being congruent to or not congruent to △A′B′C′ ?
Drag and drop each rule into the boxes to classify it as Congruent or Not Congruent.
Congruent Non Congruent
Choices to go to either congruent or non congruent
(x,y)----(x+5,y) (x,y)---(5x,5y) (x,y)-----(0.5x, 0.5y) (x,y)-----(x,-y) (x,y)------(-x,-y)
Answer:
(x,y)→(x+5,y) will be congruent; (x,y)→(5x,5y) will not be congruent; (x,y)→(0.5x, 0.5y) will not be congruent; (x,y)→(x,-y) will be congruent; (x,y)→(-x,-y) will be congruent.
Step-by-step explanation:
The types of translations that result in congruent images are translations or slides; reflections; and rotations.
Translations will add to the x- and y-coordinates; this is why the first transformation is congruent.
Reflections will negate one or more of the coordinates; this is why the fourth and fifth transformations are congruent.
The remaining two are dilations; these are stretches or shrinks that occur when the coordinates are multiplied by a number other than 1. These change the size of the figure, which is why they are not congruent.

what is the solution to this equation? 4x^2+98=0
Follow below steps;
The equation to solve is 4x² + 98 = 0.
1. Subtract 98 from both sides to get 4x² = -98.
2. Divide by 4 to obtain x² = -24.5.
3. Take the square root, remembering that √(-1) = i, so x = ±√24.5i.

Which angle is the included angle for DE¯¯¯¯¯ and FE¯¯¯¯¯ ?
∠D
∠E
∠F
Answer: ∠E
Step-by-step explanation:
The included angle for [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] is [tex]\angle{E}[/tex].
The included angle for any two lines or line segments is represented by the common vertex point.
For example : The included angle for [tex]\overline{AB}[/tex] and [tex]\overline{BC}[/tex] is [tex]\angle{B}[/tex] [Since B is the common end point in [tex]\overline{AB}[/tex] and [tex]\overline{BC}[/tex] ]
Similarly, the included angle for [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] is [tex]\angle{E}[/tex] (Since E is the common vertex in [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] )

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y ≥ −3x + 3
y is less than 3 over 2 times x minus 6
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (−6, 3) included in the solution area for the system? Justify your answer mathematically. (4 points)
Answer:
The point (-6,3) is not included in the solution area for the system.
Step-by-step explanation:
The given inequities are
[tex]y\geq -3x+3[/tex] .... (1)
[tex]y<\frac{3}{2}x-3[/tex] .... (2)
Part A: The related equations are
[tex]y=-3x+3[/tex]
[tex]y=\frac{3}{2}x-3[/tex]
Put x=0 in the above equation to find the y-intercept and put y=0, to find the x-intercept.
[tex]y=-3(0)+3=3[/tex]
The y-intercept of first equation is 3.
[tex]0=-3x+3\Rightarrow x=1[/tex]
The y-intercept of first equation is 1.
[tex]y=\frac{3}{2}(0)-3=-3[/tex]
The y-intercept of second equation is -3.
[tex]0=\frac{3}{2}x-3\Rightarrow 2[/tex]
The y-intercept of first equation is 2.
The related line of inequality (1) is a solid line because the sign of inequality is ≥ and the related line of inequality (2) is a dotted line because the sign of inequality is <.
Shaded portion of first inequality is above the related line and the shaded portion of second inequality is below the related line.
The solution area is shown in the below graph.
Part B: The point (−6, 3) is not included in the solution area for the system.
Check the given inequalities by the point (-6,3).
[tex]3\geq -3(6)+3[/tex]
[tex]3\geq -18+3[/tex]
[tex]3\geq -15[/tex]
This statement is false.
Therefore the point (-6,3) is not included in the solution area for the system.
