Answer:
6,368 chocolate
Step-by-step explanation:
First, we need to find the mass of chocolate chips in the bag:
Mass of Chocolate Chips=Mass of Chocolate Chips + Bag - Mass of Bag ONLY
Mass of Chocolate Chips = 2041 g - 67 g
Mass of Chocolate Chips = 1974 g
Next, we need to use the given information to estimate the number of chocolate chips in the bag:
31 grams of chocolate chips = 100 chips
1 gram of chocolate chips = 100/31 chips
Using this conversion factor, we can find the estimated number of chocolate chips in the bag:
1974 g of chocolate chips = (100/31) x 1974 chips
1974 g of chocolate chips ≈ 6,368 chips (rounded to four significant figures)
Therefore, it is estimated that there are about 6,368 chocolate chips in the bag.

The Pythagorean Theorem states that the square of the lengths of the two sides of a right triangle adds to the square of the length of the hypotenuse.
How do you prove Pythagorean triples?The Pythagorean Theorem states that a ² +b ² =c ² for a right-angled triangle ABC, right-angled at B. The whole integers a, b, and c form a Pythagorean triple if a and b are the lengths of the two sides of a right-angled triangle with hypotenuse c.
Draw a BD that is perpendicular to AC and meets at D. So, the Pythagorean theorem is established. Recall that the Pythagorean Theorem only applies to right-angled triangles. Two even numbers and one odd number, or all odd numbers, cannot form a Pythagorean triple. The square of an odd number is an odd number, and the square of an even number is an even number, hence this is true. A, B, and C are the three positive integers, and the Pythagorean triples are written as a ² +b ² =c ².

(d) Verify the answer of Parts (a),(b),(c) in sagemath. (1+1+1 marks) (e) (D grade question) Eve managed to access n and ϕ(n). She claims she can compute the primes p and q so that n=pq. Is this true? Justify your answer.
In this scenario, Alice and Bob have designed an RSA algorithm with a given modulus n and Bob's public key exponent e. We need to find Bob's private key d, determine the steps for Alice to send a message to Bob, and understand the decryption process for Bob. We also need to verify the answers using SageMath and assess Eve's claim about computing the primes p and q given n and ϕ(n).
a) To find Bob's private key d, we need to calculate the modular multiplicative inverse of e modulo ϕ(n). Since e = 11 and n = 152416431947009, we need to compute d such that e * d ≡ 1 (mod ϕ(n)). We can use the extended Euclidean algorithm to find the modular inverse of e. Each step in the algorithm involves finding remainders and coefficients until we obtain d.
b) To send the message 123456789 to Bob, Alice needs to encrypt it using Bob's public key (e, n). She raises the message to the power of e and takes the modulus n. The encrypted message is then sent to Bob.
c) Bob, upon receiving the encrypted message, needs to decrypt it using his private key d. He raises the encrypted message to the power of d and takes the modulus n. The decrypted message will be retrieved.
d) To verify the answers in SageMath, we can use the provided values of e, d, and n, and perform the encryption and decryption steps using the power and modulus operations.
e) Regarding Eve's claim, computing the primes p and q given n and ϕ(n) is a challenging task known as the RSA problem. It involves factoring a large composite number n, which is considered computationally difficult. Therefore, it is generally believed that it is not feasible to compute p and q efficiently given n and ϕ(n) unless there is a significant breakthrough in factoring algorithms.

Solve for x in the diagram below.
Step-by-step explanation:
Use the triangle bisector theorem:
"The angle bisector of a triangle divides the opposite side into two parts proportional to the other two sides of the triangle."
so 12 is to 16 as x is to 20
12/ 16 = x/20
20 * 12/16 = x = 15 units
Answer:
x = 15
Step-by-step explanation:
the segment inside the triangle is an angle bisector and divides the side opposite the angle into segments that are proportional to the other two sides , that is
\(\frac{12}{16}\) = \(\frac{x}{20}\) ( cross- multiply )
16x = 12 × 20 = 240 ( divide both sides by 16 )
x = 15

−8tan 1+tan2x Use appropriate identities to rewrite the following expression in terms containing only first powers of sine
By using Pythagorean identities the expression can be written as
-8 (sin ( x ) + 1 -sin 2x)
The Pythagorean identity is an important identity in trigonometry derived from the Pythagorean theorem. These identities are used to solve many trigonometric problems where, given a trigonometric ratio, other ratios can be found. The basic Pythagorean identity, which gives the relationship between sin and cos, is the most commonly used Pythagorean identity:
sin2θ + cos2θ = 1 (gives the relationship between sin and cos)
There are two other Pythagorean identities as follows :
sec2θ - tan2θ = 1 (gives the relationship between sec and tan)
csc2θ - cot2θ = 1 (gives the relationship between csc and cot)
Given expression is:
-8tanx/ 1 +tan2x
we know that:
By the Pythagorean Theorem:
1 + tan²x = sec²x
and tan x = sin x/cos x
and, sec x = 1/cos x
Now, we can write as:
-8tanx / 1 +tan²x
= -8 tan x / sec²x
= -8 sin x /cos x ÷ 1/cos²x
= -8 sin x/cos x × cos²x/1

If you accumulate 6 or more points within 3 years you are subject to a surcharge of $150. How much is the surcharge for each additional point after 6
The surcharge for each additional point after 6 is $25 per point.
This means that if you accumulate 7 points within 3 years, you will be subject to a surcharge of $175 ($150 for the first 6 points and $25 for the additional point).
If you accumulate 8 points within 3 years, the surcharge will be $200 ($150 for the first 6 points and $50 for the additional two points), and so on.
This information is based on the New Jersey Motor Vehicle Commission's (NJMVC) point system. The NJMVC assigns points for various traffic violations, such as speeding, reckless driving, and failure to yield.
If you accumulate too many points within a certain period of time, your driving privileges may be suspended or revoked.
It's important to note that the NJMVC point system is just one example of how states in the US handle driver's license points and surcharges. Each state has its own system, so it's important to check with your local Department of Motor Vehicles (DMV) or equivalent agency to understand how points and surcharges work in your area.

The Ratio Of A Screen's Width to it's height is 4:3.
The height of the screen is 24 cm.
What is it's width in centimetres (cm)?
Answer:
The height is 32
Step-by-step explanation:
The ratio of width to height is
4:3
We know the height is 24 so to go from 3 to 24 is multiplying by 8.
Multiply all terms by 8
4 * 8 : 3 * 8
32: 24
The ratio of the width to height is
32:24
The height is 32
=================================================
Work Shown
width/height = 4/3
w/24 = 4/3
3w = 24*4
3w = 96
w = 96/3
w = 32 cm is the width
-------------------
Another approach.
The ratio of width to height is 4:3, meaning a screen that has width 4 cm and height 3 cm is possible. Instead, we want the "height 3 cm" to be "height 24 cm". This is a jump of "times 8".
Multiply both parts of that ratio by 8 to get...
4:3
8*4:8*3
32:24
A screen that is 32 cm wide and 24 cm tall will give us a ratio 4:3 when simplifying fully.
The order of the numbers is important. We have the width listed first simply because it was listed first in the phrasing "ratio of width to height".

The graph of the linear equation, y = 7/2x - 2 is shown in the attachment.
How to Sketch the Graph of a Linear Equation?To sketch the graph of the linear equation y = 7/2x - 2, you can follow these steps:
Find the x-intercept(s) and y-intercept(s):x-intercepts occur when y = 0, so we can solve for x:
0 = 7/2x - 2
2 = 7/2x
4 = 7x
x = 4/7
Hence, the x-intercept is (4/7, 0).
y-intercepts occur when x = 0, so we can plug in x = 0 and solve for y:
y = 7/2 * 0 - 2 = -2
Hence, the y-intercept is (0, -2).
Plot the x-intercept(s) and y-intercept(s) on the graph.Choose two more points on the line to plot. The line passes through the x-intercept and y-intercept, so we can choose those two points. To choose additional points, you can pick any x-value and use the equation to find the corresponding y-value.Plot the points and connect them to form a straight line.You have now sketched the graph of the linear equation y = 7/2x - 2, which is shown below.
