Adrian, Ben and Charlie share some sweets in the ratio 7.4.11
Charlie got 52 more sweets than Adrian. Work out the total amount of sweets.
Answer:
286 sweets.
Step-by-step explanation:
If Adrian had x sweets, Charlie got x+52 sweets.
The number of parts is 7+4+11 = 22.
So Adrian had 7/22 of the total and Charlie had 11/22 = 1/2 of the total.
This means that Ben had 4/22 = 2/11 of the total.
If y is the total number of sweets:
y = x + x + 52 + 2y/11
9y/11 = 2x + 52
2x = 9y/11 - 52.............(1)
Also x + 52 = y/2
y = 2x + 104
2x = y - 104...............(2)
Equating (1) and (2) - (as there is 2x on left side of both equations):-
9y/11 - 52 = y - 104
52 = 2y/11
y = 52 * 11/2
y = 286 sweets.

Sixty-four percent of voters in a very large electorate support candidate Smith in an upcoming election. A student employee working the evening shift at a telephone survey facility calls voters at random and asks them which candidate they prefer. a. What is the probability that, among five voters the student calls, exactly one supports candidate Smith? b. What is the probability that, among five voters the student calls, at least one supports candidate Smith? c. What is the probability that the first voter supporting candidate Smith is reached on the fifth call, i.e., what is the probability that it takes the student five calls to reach the first voter who supports candidate Smith? d. What is the probability that the third voter supporting candidate Smith is reached on the fifth call, i.e., what is the probability that it takes the student five calls to reach three voters who supports candidate Smith?
The probabilities are calculated assuming independence of each call and that the success probability remains constant throughout the calls.
a. The probability that, among five voters the student calls, exactly one supports candidate Smith can be calculated using the binomial probability formula. With a success probability of 64% (0.64) and exactly one success (k = 1) out of five trials (n = 5), the probability can be calculated as follows:
\[
P(X = 1) = \binom{5}{1} \times (0.64)^1 \times (1 - 0.64)^4
\]
The calculation results in approximately 0.369, or 36.9%.
b. The probability that, among five voters the student calls, at least one supports candidate Smith can be calculated as the complement of the probability that none of the voters support Smith. Using the binomial probability formula, with a success probability of 64% (0.64) and no success (k = 0) out of five trials (n = 5), the probability can be calculated as follows:
\[
P(X \geq 1) = 1 - P(X = 0) = 1 - \binom{5}{0} \times (0.64)^0 \times (1 - 0.64)^5
\]
The calculation results in approximately 0.997, or 99.7%.
c. The probability that the first voter supporting candidate Smith is reached on the fifth call can be calculated as the probability of not reaching a Smith supporter in the first four calls (0.36) multiplied by the probability of reaching a Smith supporter on the fifth call (0.64):
\[
P(\text{{First Smith Supporter on Fifth Call}}) = (1 - 0.64)^4 \times 0.64
\]
The calculation results in approximately 0.014, or 1.4%.
d. The probability that the third voter supporting candidate Smith is reached on the fifth call can be calculated as the probability of reaching two Smith supporters in the first four calls (0.64 for the first call, 0.36 for the second call, and 0.36 for the third call) multiplied by the probability of reaching a Smith supporter on the fifth call (0.64):
\[
P(\text{{Third Smith Supporter on Fifth Call}}) = (0.64)^2 \times (1 - 0.64) \times 0.64
\]
The calculation results in approximately 0.147, or 14.7%.

if the l 2l 2 norm of the vector aa is greater than the l 2l 2 norm of the vector bb, it is not always true that the l 1l 1 norm of aa is greater than the l 1l 1 norm of bb
The L1 norm of vector A is greater than or equal to the L1 norm of vector B.
How did we arrive at this assertion?Basically, if the L2 norm of vector A is greater than the L2 norm of vector B, it is indeed always true that the L1 norm of vector A is greater than or equal to the L1 norm of vector B. The Lp norm is defined as follows:
\(||x||_p = (|x_1|^p + |x_2|^p + ... + |x_n|^p)^(1/p),\)
where x = [x₁, x₂, ..., xₙ] is a vector.
For the L2 norm (p = 2), the formula is:
\(||x||_2 = \sqrt(|x_1|^2 + |x_2|^2 + ... + |x_n|^2).\)
For the L1 norm (p = 1), the formula is:
\(||x||₁ = |x_1| + |x_2| + ... + |x_n|.\)
If ||A||₂ > ||B||₂, it implies that:
\(\sqrt(|A_1|^2 + |A_2|^2 + ... + |A_n|^2) > \sqrt(|B_1|^2 + |B_2|^2 + ... + |B_n|^2).\)
Squaring both sides of the inequality, we get:
\(|A_1|^2 + |A_2|^2 + ... + |A_n|^2 > |B_1|^2 + |B_2|^2 + ... + |B_n|^2.\)
Since the squares of the magnitudes are positive, we can conclude that:
\(|A_1| + |A_2| + ... + |A_n| > |B_1| + |B_2| + ... + |B_n|.\)
Therefore, the L1 norm of vector A is greater than or equal to the L1 norm of vector B.

What is the Corresponding Angles Theorem?If two triangles are similar to each other, their corresponding angles would be equal. Also, based on the corresponding angles theorem, corresponding angles are equal to each other.
Triangles IHJ and FGH are similar to each other, therefore, angles HFG and HIJ are corresponding angles.
Therefore:
The measure of angle HFG = the measure of angle HIJ
m∠HFG = 57 − 6x
m∠HIJ = −4x + 49
Thus:
57 − 6x = -4x + 49
Combine like terms
4x - 6x = -57 + 49
-2x = -8

What is the equation of the line that passes through the point (5, – 7) and
has a slope of o?
Answer:
The answer is
\(y = - 7\)
Answer:
y = -7
Step-by-step explanation:
Hey :)
y = mx + b
*m is equal to the slope...
y = (0)x + b
Plug in the point you have...
-7 = (0) (5) + b
-7 = 0 + b
-7 = b
y = (0)x - 7
y = -7
Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.
Answer: y = -7

assume that hamilton corporation has pre-tax income of $100,000, tax expense of $22,500, and an after-tax income of $77,500. what is hamilton effective tax rate?
Hamilton Corporation's effective tax rate is 22.5%.
The effective tax rate is a measure of a company's tax burden as a percentage of its pre-tax income. It indicates the proportion of pre-tax income that is paid in taxes.
In this case, Hamilton Corporation has a pre-tax income of $100,000 and a tax expense of $22,500. Therefore, the company paid $22,500 in taxes out of its pre-tax income of $100,000.
The effective tax rate is the ratio of the total tax expense to the company's pre-tax income.
Effective Tax Rate = Total Tax Expense / Pre-tax Income
In this case, the pre-tax income is $100,000, and the tax expense is $22,500. Therefore,
Effective Tax Rate = $22,500 / $100,000 = 0.225 or 22.5%

The height of the tower is 969 feet.
Let CD be the tower and A be the point from a window in the building, a person determines that the angle of elevation to the top of the tower is 42 degrees.
In triangle AED
tan42° = ED/AE
tan42° = h₁/615
h₁ = tan42° × 615
= 553.74
Rounding to the nearest integer
h₁ = 554
In triangle AEC
tan34° = EC/AE
tan34° = h₂/615
h₂ = tan34° × 615
= 414.82
Rounding to the nearest integer
h₂ = 415
Height of tower = EC + ED
= h₁ + h₂

1) If ∑Cn(x–3)^n converges at x=7 and diverges at x=10, what can you say about the convergence at x=11? At x=5? At x=0?
At x=0, we can say that the series ∑\(Cn(X - 3)^n\) converges, as the given condition for convergence is satisfied at x=7, x=10, and x=0 is between the two values.
At x=11, we can say that the series ∑\(Cn(X - 3)^n\) converges, as the given condition for convergence is satisfied at x=7 and x=11 is between the two values. At x=5, we can say that the series ∑\(Cn(X - 3)^n\) diverges, as the given condition for convergence is not satisfied at x=5.
The theory behind the question is the idea of a power series, which is an infinite series of terms where each term is a power of a variable raised to a constant. In this case, we have a series of the form:
\(Cn(X - 3)^n\)
here Cn is a constant. The question is asking about the behavior of this series as a function of the variable x, specifically whether it converges or diverges. The condition for convergence of a power series is that the absolute value of the coefficients (i.e., the absolute value of Cn) must be less than or equal to 1 for all values of x in the interval where the series is defined. If this condition is satisfied, then the series converges.

f(x + a) when the translation is by a units to the left.
f(x - a) when the translation is by a units to the right.
Looking at the coordinates of the points given on f(x) and g(x), we can see that g(x) is just f(x) translate 2 units to the left.
Hence, if f(x) = 2ˣ
