You select a card from a deck that contains 25 red cards, 12 blue cards, 8 yellow cards, and 5 red cards. What is the probability of drawing a red card?
Answer: 3/14!
Your welcome!
Step-by-step explanation: The probability P is actually formulated as "the successful outcomes S" over "the total number of possible outcomes T," that is P = S/T You are expecting to draw a blue card. Therefore the probability will beP (one blue card) = 6/28 = 3/14!

What is the range of the function g(x) = |x – 12| – 2?.
The range of the given function is [-2,∞).
what is the range of a function?the range is the complete set of all possible values of the dependent variable say 'y'.
given function is: f(x)= |x – 12| – 2
f(x) = x-14 ∀ x≥12
f(x) = -x+10 ∀ x < 12
value of the above function at x=12 will be -2 means the minimum value of the function will be -2.
now, from the graph, we can see that f(x) is leading to infinity
so the range will be [-2,∞).
therefore, The range of the given function is [-2,∞).

4. Choose an initial value that is less than zero. What happens to the value of the function as the number of iterations increases?
Step-by-step explanation:
The initial value of a function is the output value of the function when the input value is 0. For example, if your function is tracking how much money you made over a certain amount of time, then the initial value would be however much money you had to begin with on day 0.
A triangle has angle measures that are related as follows:
• The largest angle is eight times the smallest angle.
• The middle angle is triple the smallest angle..
a) write an equation to model the relationship
b) solve the equation and then determine the measure of each angle. Sketch the triangle and label the angle measures.
Answer:
a) a +8a +3a = 180°
b) 15°, 45°, 120°
c) see attached
Step-by-step explanation:
a)Let 'a' represent the measure of the smallest angle. The largest angle is 8a, and the middle angle is 3a. The sum of angles, as always, is 180°.
a +8a +3a = 180° . . . . . . equation modeling the relationship

If three times a number is increased by 24, the result is 16 less than seven times the same number. Find the number.
Answer:
10
Step-by-step explanation:
let x = unknown number
three times x is increased by 24
so 3x + 24
this is equal to 16 less than 7 times x
so 3x + 24 = 7x - 16
we now solve for x
3x + 24 = 7x - 16
add 16 to both sides
3x + 24 + 16 = 7x - 16 + 16
3x + 40 = 7x
subtract 3x from both sides
3x - 3x + 40 = 7x - 3x
40 = 4x
divide both sides by 4
40/4 = 10
4x / 4 =x
x=10
the unknown number is 10

o.
To finish his construction, Zahid needs to draw segments DF,V, and
The joining of each three, two penultimate points on the circumference
of the circle, without intersection gives an equilateral triangle.
Response:
The segments that Zahid needs to draw are; DF, BF, and BDHow can the equilateral triangle be constructed from the given construction on the circle?The assumption can be taken that, the steps used to construct the
equilateral triangle inscribed in the circle by marking along the
circumference of the circle at 6 points using the radial length.
Therefore;
The lengths of the chords formed by joining a marked points to another point such that one marked point is between the two are equal.
Which gives;
The length of the chord, DF = The length of the chord, BF = The length of the chord, BD
Given that the joining DF, BF and BD forms a triangle, and DF = BF = BD, we have;

This is because each term is increasing by the same amount (2) each time.
3+2 = 55+2 = 77+2 = 99+2 = 11--------------------------------------------
The table on the right is geometric
Why? Because this time we are multiplying each term by the same value (2) to get the next term.
3*2 = 66*2 = 1212*2 = 2424*2 = 48Both involve the number 2, but the first table uses addition while the second table uses multiplication.
