Answers
Answer:
26 minutes
Step-by-step explanation:
Since the mean is the average of all the number, we need to reach a total of 315 minutes for the entire week.

(a) sinâ1(â3/2)
b) cosâ1(1/2)
Answers
The expression of sine function of sinâ1(â3/2) is undefined. The value of cosâ1(1/2) = π/3 radians.
The expression sinâ1(â3/2), since the sine function is only defined for angles between -π/2 and π/2, we cannot find an angle with a sine of -â3/2. Therefore, the expression is undefined.
The expression cosâ1(1/2), Since the cosine function is positive for angles between 0 and π, we know that the angle we are looking for is in the first or fourth quadrant.
To find the angle, we can use the inverse cosine function, which gives us the angle whose cosine is equal to the given value. Therefore, we have
cosθ = 1/2
Taking the inverse cosine of both sides, we get
θ = cos⁻¹(1/2)
Using the unit circle or trigonometric identities, we can find that cos⁻¹(1/2) = π/3 or 2π/3. Since the cosine function is positive in the first quadrant and negative in the fourth quadrant, we choose the solution in the first quadrant, which is θ = π/3.
Therefore, cosâ1(1/2) = π/3 radians.

Find a power series representation for 1+x31 and give its radius of convergence. Deduce a series whose sum is ∫01/21+x31dx
Answers
We know that\(`lim_(n->∞)|a(n+1)/a(n)| = lim_(n->∞)|n3/3n| = 1`\)
The radius of convergence \(`R` is `R = 1/1 = 1`.\)
To determine the interval of convergence, we test the endpoints\(`x = -1` and `x = 1`.\)
When \(`x = -1`,\)
the series becomes \(`∑n=1+[infinity](−1)^nn3n`.\)
We can write\(`2 + x^(1/2)` as `2(1 + (1/2)x^(1/2))`. \\)
Therefore, we can start with the power series representation of\(`1 + x^(1/2)`\)and multiply by `2`. We have:
\(```1 + x^(1/2) = ∑n=0+[infinity][(1/2)nCnx^n/2^n] (by the binomial series)2 + x^(1/2) = 2∑n=0+[infinity][(1/2)nCnx^n/2^n] = ∑n=0+[infinity][2(1/2)nCnx^n/2^n]```\)
The radius of convergence of\(`1 + x^(1/2)` is `R = 1`\).
Therefore, the radius of convergence of \(`2 + x^(1/2)`\) is also `R = 1`.
4. We can write \(`1 + x^(1/3)` as `(x^(1/3))/(x^(1/3)) + 1 = (x^(1/3))(1 + x^(-1/3))`.\)
Therefore, we can start with the power series representation of\(`1 + x`\)and substitute\(`x^(1/3)`\)for `x`. We have:
\(```1 + x = ∑n=0+[infinity][x^n]1 + x^(1/3) = ∑n=0+[infinity][x^(n/3)]```\)
Therefore, the power series representation of \(`1 + x^(1/3)`\) is:
\(```1 + x^(1/3) = ∑n=0+[infinity][x^n/3^n]```\)
The radius of convergence of \(`1 + x` is `R = 1`.\)
Therefore, the radius of convergence of \(`1 + x^(1/3)`\) is also `R = 1`. We can integrate term-by-term to obtain:
\(```∫01/2(1 + x^(1/3)) dx= ∑n=0+[infinity][∫01/2x^n/3^n dx]= ∑n=0+[infinity][1/(n+1)(3^n)(2^(n+1)/3 - 1/3)]```\)

C) PV = FVn x (1 + r)
D) PV = FV x 1/(1 + r)^n
Answers
The correct formula for finding the present value of an investment is given by option D) PV = FV x 1/(1 + r)^n.
The present value (PV) of an investment is the current value of future cash flows discounted at a specified rate. The formula for calculating the present value takes into account the future value (FV) of the investment, the interest rate (r), and the number of periods (n).
Option D) PV = FV x 1/(1 + r)^n represents the correct formula for finding the present value. It incorporates the concept of discounting future cash flows by dividing the future value by (1 + r)^n. This adjustment accounts for the time value of money, where the value of money decreases over time.
In contrast, options A), B), and C) do not accurately represent the present value formula and may lead to incorrect calculations.

the average number of shoppers at a particular grocery store in one day is 505, and the standard deviation is 115. the number of shoppers is normally distributed. for a random day, what is the probability that there are between 250 and 450 shoppers at the grocery store?
Answers
For a random day with the standard deviation, the probability that there are less than 300 shoppers on a random day, is 0.00585.
Probability is a measure of the likelihood that an event will occur.
Many events cannot be predicted with absolute certainty. We can only predict the probability that an event will occur, i.e. how likely it is to occur, using it.The average total number of shoppers on a grocery store in 1 day is 505; the standard deviation is 115.
Let, X be the random variable denoting the number of shoppers on a random day.
Then, X follows normal with mean 505 and standard deviation of 115.
Then, we can say that,
Z=(X-505)/115 follows standard normal with mean 0 and standard deviation of 1.
We have to find
P (250 <X< 450)
= P {(250-505)/155} < Z < {(450-505)/155}
= P (-1.64 <Z< -0.03)
Where, Z is the standard normal variate.
ρ = -1.64 <ρ< -0.03
Where, ρ is the distribution function of the standard normal variate.
From the standard normal table, this becomes
=0.00585
For a random day, the probability that there are less than 300 shoppers on a random day, is 0.00585.

(a) how many cards are in a complete deck of set? (b) how many unique sets are there? when three cards form a set, we can also count the number of attributes for which all three cards are the same. for example, in the set below, all three cards have the same color, and the same shape (but they have different numbers of shapes and different shading). (c) find the number of sets where all three cards are the same for exactly 0 attributes. (d) find the number of sets where all three cards are the same for exactly 1 attribute. (e) find the number of sets where all three cards are the same for exactly 2 attributes. (f) find the number of sets where all three cards are the same for exactly 3 attributes.
Answers
For A, I got 81 cards. I'm pretty sure that's correct.
For B , there can be 1 attribute that is different and the other 3 can be the same, there can be 2 that are different and 2 can be the same, there can be 3 that are different and 1 is the same, or all 4 attributes are different.
If 1 is different and the other 3 are the same, there are \($\binom{4}{1}\)= 4$ sets.
If there are 2 different and 2 are the same, there are\($\binom{4}{2}\)= 6$ sets.
If there are 3 different and 1 is the same, there are \($\binom{4}{2}\) = 4$ sets.
But I don't know how many sets there are if all 4 are different.
To get my final answer for b, I would add all the sets up.
(b) There are 108/3 = 36 unique sets.
(c) For the first card, there are 3 ways to choose the number. For the second, there 2 choices, and then there is only 1 choice. So there are 3*2*1 = 6 ways that the numbers can be chosen. Doing this for the other attributes, we get 6*6*24*6 ways. But the order of cards doesn't matter in a set, so we divide by 3!: 6*6*24*6/3! = 864. So there are 864 sets for part (c).
(d) The cards can have the same number, color, shape, or shading. If all the colors are the same, then there are 6*24*6/3! = 144 sets. If all the numbers are the same, then there are 144 sets. We get the same number for shape and shading, so there are 4*144 = 576 sets for part (d).
(e) We need to choose two of the attributes. There are C(4,2) = 6 ways of choosing two attributes. For each of these two attributes, there are 3 options. For the other two attributes, there are 3 ways of assigning the choices, so there are 6*3*3*3*3 = 486 sets for part (e)
(f) First we choose which attributes are the same. There are C(4,3) = 4 ways of choosing which attributes are the same. There are then 3*3*4 = 36 ways to assign which is which for each of these three attributes, and there are 4 ways to assign the choices for the fourth attribute, so there are 4*36*4 = 576 sets for part (f).
As for c, d, e, and f, I'm pretty sure I can just refer to b.

pls help will mark as brainlist
Answers
Step-by-step explanation:
the lengths OB, OC & BC together forms a isosceles triangle.
therefore,
OB=OC
3x+4=x+8
2x=4
x=2.
OB = 3x+4= 3.2+4=10cm.
OC= x+8= 2+8=10cm.
therefore, the diagonals are : 20cm each.
hope this helps you.
the hypotenuse of a right triangle measures 12 centimeters and its shorter leg measures 4 centimeters. what is the measure of the larger acute angle of the triangle? round your answer to the nearest tenth of a degree.
Answers
The measure of the larger acute angle of the right triangle is 73.7°. This can be calculated using trigonometry and the Pythagorean theorem.
The larger acute angle of the triangle can be found using trigonometry. First, we can find the length of the other leg using the Pythagorean theorem: a² + b² = c², where c is the hypotenuse and a and b are the legs. Plugging in the values we get: 4² + b² = 12², solving for b we get b = √(12² - 4²) = 8√3. Now we can use inverse tangent to find the larger acute angle: tan⁻¹(opposite/adjacent) = tan¹⁽⁸√³/⁴⁾ ≈ 73.7°. So, the measure of the larger acute angle is 73.7°.
