Using it's concept, it is found that there is a 0.1765 = 17.65% probability that a learner chosen at random from the field trip has an orange but not an apple.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, of the 85 learners, 75 - 60 = 15 have an orange but not an apple, hence the probability is given by:
p = 15/85 = 0.1765.
0.1765 = 17.65% probability that a learner chosen at random from the field trip has an orange but not an apple.

The x-intercept of the continuous function shown in the table is, (2, 0)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Slope = -7+8/1
slope=1
You can see the values of x and f(x) from the given table.
An ordered pairs is in the form of (x, f(x)).
By x-intercept definition;
at x =2
⇒ f(x) = 0
Therefore, the x-intercept of the continuous function shown in the table is, (2, 0)

2 7/9 divided by 5/6 in fraction.
The fraction after the division is A = 46 / 15
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the first fraction be p = 2 7/9
Let the second fraction be q = 5/6
Now , A = p/q
On simplifying the equation , we get
A = 2 7/9 / 5/6
A = ( 25/9 ) / ( 5/6 )
A = ( 25/9 ) x ( 6/5 )
On simplifying , we get
A = 138/45
A = 46 / 15
Hence , the fraction is A = 46/15

You invested $11,000 in two accounts paying 3% and 7% annual interest, respectively. If the total interest earned for the year was $730, how much was invested at each rate? The amount invested at 3% is $
Answer:
I invested $ 10,000 at 7% per year, and $ 1,000 at 3% per year.
Step-by-step explanation:
Given that I invested $ 11,000 in two accounts paying 3% and 7% annual interest, respectively, if the total interest earned for the year was $ 730, to determine how much was invested at each rate, the following calculation must be performed:
5,000 x 0.07 + 6,000 x 0.03 = 530
8,000 x 0.07 + 3,000 x 0.03 = 650
10,000 x 0.07 + 1,000 x 0.03 = 730
Therefore, I invested $ 10,000 at 7% per year, and $ 1,000 at 3% per year.
Answer:
A 3% = 1000 and B 7% = 10000
Step-by-step explanation:
A + B = 11000
A * 0.03 + B * 0.07 = $730
A = 11000 - B
(11000 - B)*0.03 + B*0.07 = 730
330 - 0.03B + 0.07B = 730
330 + 0.04B = 730
0.04B = 400
B = 10000
A = 11000 - B = 11000 - 10000
A = 1000

What is the area of the triangle in the diagram?
Answer:
B.
Step-by-step explanation:
the area of a triangle is
Area = baseline × height / 2
the baseline can be any of the 3 sides.
the height is then the perpendicular connection from the corner point opposite of the chosen line to the chosen line.
in this example the easiest approach would be to pick (x1,y1) to (x2,y1) as baseline, and the height would then be the piece of the y-axis from (0,0) to the baseline.
so, how long is the baseline ?
we need to calculate the difference between the coordinates of both corner points.
we have here an easy case, as both points have the same y value, so we only need to look at the difference in x.
baseline = x2 - x1
and the height is here simply (because of the special case) the difference of the baseline from (0,0) on the y-axis
height = y1
therefore, the area of the triangle is
Area = (x2-x1) × y1 / 2 = 1/2 × y1(x2-x1) = solution B
if the corner points and height are not so nicely aligned with the coordinate axis, then we need to calculate the distances by using Pythagoras to determine the "Hypotenuse" of the triangles created by the differences of the individual coordinates.
in our example
((x1,y1) to (x2,y1))² = (x2-x1)² + (y1-y1)² = (x2-x1)² + 0 = (x2-x1)²
and therefore
(x1,y1) to (x2,y1) = (x2-x1)
and we are back to our original solution.

Answer:
A. JK = 12, JK is parallel to LM
D. JK = 8, JM = 12
Step-by-step explanation:
Based on the given figure above, the additional facts that would guarantee that JKLM is a parallelogram are answers A and D.
By definition, a parallelogram is a figure that has opposite sides parallel or it has two pairs of sides that are parallel.
The additional facts that would guarantee that JKLM is a parallelogram are
JK = 8 and JM = 12.
Option B is the correct answer.
What is a parallelogram?Parallelogram is a quadrilateral that has two pairs of parallel sides.
In a parallelogram, opposite sides and angles are equal.
The adjacent angles add up to 180 degrees.
We have,
In a parallelogram,
The opposite sides are parallel and so the sides are also equal.
Now,
KL and JM are parallel.
So,
KL = JM = 12
And,
KJ and LM are also parallel.
So,
KJ = LM = 8
Thus,
The additional facts that would guarantee that JKLM is a parallelogram are
JK = 8 and JM = 12.

You are to play the following game of cards. Cards are worth their face value, Jacks, Queens and Kings are also worth 10 and Aces are worth 11. You pull precisely two cards from a standard deck and if their sum is at least 20, then you win the game and are given a prize of cash. It costs you $10 to play the game. At least how much should the prize be in order to make your expected winnings positive
Answer:
$82.875
Step-by-step explanation:
From the given information:
Assume F is used to denote the two cards;
If there are four aces among 52 playing cards, the chance of selecting the first ace is = [tex]\dfrac{4}{52}[/tex]
After selecting the first ace, we have only 3 aces remaining and a total of 51 playing cards. Thus, the chance of selecting the second ace will be [tex]\dfrac{3}{51}[/tex]
By applying product rule, we can determine the chance of selecting two aces without replacement as follows:
i.e.
[tex]P(F=22)=\dfrac{4}{52}\times \dfrac{3}{51}[/tex]
[tex]= \dfrac{1}{221}[/tex]
The probability of getting one ace, one face is:
[tex]P(F=21) =( \dfrac{4}{52}\times \dfrac{12}{51})+( \dfrac{12}{52}\times \dfrac{4}{51})[/tex]
[tex]P(F=21) = \dfrac{4}{221}\times\dfrac{4}{221}[/tex]
[tex]P(F=21) = \dfrac{8}{221}[/tex]
Since there are 4 aces, 4 nine, and 12 faces in a card deck
The probability of getting one ace, one nine, or two faces now will be:
[tex]P(F=20) = (\dfrac{4}{52} \times \dfrac{4}{51})+ (\dfrac{4}{52} \times \dfrac{4}{51}) + (\dfrac{12}{52} \times \dfrac{11}{51})[/tex]
[tex]P(F=20) = (\dfrac{53}{663} )[/tex]
Now, the probability of at least 20 now is:
[tex]\text{P(F at least 20)} = \dfrac{1}{221}+\dfrac{8}{221}+\dfrac{53}{663}[/tex]
[tex]\text{P(F at least 20)} = \dfrac{80}{663}[/tex]
If H represents the amount of prize of the expected winnings:
Then;
[tex](H - 10) (\dfrac{80}{663}) + (-10)(\dfrac{663-80}{663}) = 0[/tex]
[tex]\dfrac{80(H-10)}{663}-\dfrac{5830}{663}=0[/tex]
[tex]\dfrac{80(H-10)}{663}=\dfrac{5830}{663}[/tex]
80H - 800 = 5830
80H = 5830 +800
80H = 6630
H = 6630/80
H = $82.875
The prize should be $82.875 to make a winning positive.
