Answer:
The total number of fruits Halston can choose is 3 + 4 + 2 = 9.
The number of ways she can choose two fruits without restrictions is 9C2 = (98)/(21) = 36.
The number of ways she can choose two fruits where both are bananas is 2C2 = 1.
Therefore, the number of ways she can choose two fruits that are not bananas is 36 - 1 = 35.
So, the probability that Halston chooses two fruits that are not bananas is:
35/36
Therefore, the probability that Halston chooses two fruits that are not bananas is 35/36.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.
Answer:
Step-by-step explanation:
Let x be the measure of the first angle.
According to the problem, we know that:
The sum of the angles of the triangle is 180: x + y + z = 180
The sum of the second and third angles is five times the measure of the first angle: y + z = 5x
The third angle is 16 more than the second: z = y + 16
We can substitute the third equation into the second equation to get:
y + (y + 16) = 5x
Simplifying this equation, we get:
2y + 16 = 5x
We can rearrange this equation to get:
y = (5/2)x - 8
Now we can substitute this equation and the equation z = y + 16 into the first equation to get:
x + (5/2)x - 8 + (5/2)x + 8 = 180
Simplifying this equation, we get:
6x = 360
Dividing both sides by 6, we get:
x = 60
Now we can use this value of x to find y and z:
y = (5/2)x - 8 = (5/2)(60) - 8 = 58
z = y + 16 = 58 + 16 = 74
Therefore, the measures of the three angles are x = 60, y = 58, and z = 74.

What is the effective interest rate of a simple discount note for $3,500 at a bank discount rate of 11%, for 24 months?
The effective interest rate of the simple discount note is 6%.
The effective interest rate (EIR) of a simple discount note can be calculated using the following formula:
EIR = (Discount ÷ Face Value) x (360 ÷ t)
Where Discount is the difference between the face value and the discounted value, t is the time in days from the issuance of the note until its maturity, and 360 is the number of days in a year used for interest rate calculations.
In this case, the face value is $3,500, the bank discount rate is 11%, and the time to maturity is 24 months or 720 days.
Discounted value = Face value x (1 - Bank discount rate x t ÷ 360)
Discounted value = $3,500 x (1 - 0.11 x 720 ÷ 360)
Discounted value = $3,080
Therefore, the discount is $420 ($3,500 - $3,080).
Using the formula for EIR, we get:
EIR = ($420 ÷ $3,500) x (360 ÷ 720)
EIR = 0.06 or 6%

4) It has been known that 18% of victims of financial fraud know the perpetrator of the fraud
personally. If a sample of 156 people were victims of fraud, what is the mean number of those
victims that know the perpetrator of the fraud personally?
Answer:
If 18% of victims of financial fraud know the perpetrator of the fraud personally, and a sample of 156 people were victims of fraud, we can find the mean number of those victims that know the perpetrator by multiplying the sample size by the percentage. Therefore, the mean number of victims that know the perpetrator is 156 x 0.18 = 28.08. However, since we cannot have a fraction of a person, we can round the answer to the nearest whole number. Therefore, the mean number of victims that know the perpetrator is 28.

Find the average rate of change of g(x) = 3x² + 3 on the interval [ - 9, 4].
Answer:
-15
Step-by-step explanation:
You want the average rate of change of g(x) = 3x² +3 on the interval [-9, 4].
Average rate of changeThe average rate of change is defined as ...
AROC(g) = (g(b) -g(a))/(b -a)
We can evaluate this directly, or we can simplify it a bit first.
AROC = ((3b² +3) -(3a² +3))/(b -a)
= (3b² -3a²)/(b -a)
= 3(b -a)(b +a)/(b -a)
= 3(b +a)
Interval [-9, 4]The AROC on the interval [a, b] = [-9, 4] is then ...
AROC = 3(4 +(-9)) = 3(-5)
AROC = -15

A capsule of paracetamol is made of a cylinder and a hemisphere at each end. The total length of the capsule is 20 mm and the width is 6 mm.
Calculate:
(a) What is the length of the cylinder? (b) Find the volume of the cylinder, to 3 significant figures
(c) Find the volume of the two hemispheres
(d) What is the total volume of the capsule?
Answer:
Step-by-step explanation:
To solve this problem, we can use the following formulae for the volume of a cylinder and a hemisphere:
Volume of a cylinder = πr²h
Volume of a hemisphere = 2/3πr³/2
where r is the radius of the cylinder or hemisphere, and h is the height of the cylinder.
(a) To find the length of the cylinder, we can subtract the combined length of the two hemispheres from the total length of the capsule:
Length of cylinder = Total length of capsule - 2 × radius of hemisphere
Length of cylinder = 20 mm - 2 × 3 mm (radius of hemisphere)
Length of cylinder = 14 mm
(b) To find the volume of the cylinder, we need to know the radius and height. Since the width of the capsule is given as 6 mm, and we know that the cylinder runs the full length of the capsule, we can use the following formula to find the radius of the cylinder:
Width = 2 × radius of hemisphere + diameter of cylinder
6 mm = 2 × 3 mm + diameter of cylinder
Diameter of cylinder = 6 mm
Radius of cylinder = 3 mm
Now we can use the formula for the volume of a cylinder to find the volume of the cylinder:
Volume of cylinder = πr²h
Volume of cylinder = π(3 mm)² × 14 mm
Volume of cylinder ≈ 395.8 mm³ (to 3 significant figures)
(c) The radius of each hemisphere is 3 mm (since they have the same radius as the cylinder), so we can use the formula for the volume of a hemisphere to find the volume of each hemisphere:
Volume of hemisphere = 2/3πr³/2
Volume of hemisphere = 2/3π(3 mm)³/2
Volume of hemisphere ≈ 56.55 mm³ (to 3 significant figures)
(d) To find the total volume of the capsule, we can add the volumes of the cylinder and the two hemispheres:
Total volume of capsule = Volume of cylinder + 2 × Volume of hemisphere
Total volume of capsule ≈ 509.9 mm³ (to 3 significant figures)
Therefore, the length of the cylinder is 14 mm, the volume of the cylinder is approximately 395.8 mm³, the volume of each hemisphere is approximately 56.55 mm³, and the total volume of the capsule is approximately 509.9 mm³.

percentage = (4250 / 6500) x 100%
percentage = 0.6538 x 100%
percentage = 65.38%
Therefore, $4250 represents 65.38% of $6500.

A triangle has sides with lengths of 8 meters, 15 meters, and 17 meters. Is it a right triangle?
A Right Triangle must satisfy the Converse of the Pythagorean Theorem: [tex]a^2 + b^2 = c^2[/tex]
From the given side lengths, let a = 8, b = 15, c = 17 (c cannot be less than a or b)
[tex]a^2 + b^2 = (8)^2 + (15)^2[/tex]
[tex]a^2 + b^2 = 64 + 225 = 289[/tex]
[tex]c^2 = (17)^2 = 289[/tex]
[tex]a^2 + b^2 = c^2 \ (289 = 289)[/tex]
Therefore, a Triangle with side lengths of 8, 15 and 17 is a Right Triangle
Note: Since the side lengths are positive integers and the GCF(8, 15, 17) = 1, they are a primitive Pythagorean Triple.
