3. A telephone calling center performs two types of solicitations: (1) donations and (2) sales. The center wants to determine how much time on average a caller spends on each type of solicitation. The issue is complicated by the fact that some calls get busy signals, some go unanswered, and some last for less than one minute, which is interpreted to mean that the recipient is not interested or
Answer:
hang ups the receiver
Step-by-step explanation:
In this case, there is a difficulty for the call center to determine the average time that each caller spends on each type of request, since there is also the possibility that the recipient will not be interested in the call or hang up when receiving such a call. Therefore, in order to calculate this average in a more real way, the company must statistically monitor this data in relation to each hour of work and how many situations occurred in that hour, how many calls received were answered, how many received a busy signal, how many are not answered and how many calls last less than a minute if the recipient is not interested or hangs up.
Through this data, the company is able to monitor the calls and define telephone service strategies that can retain the customer more if the calls in less than a minute exceed conventional calls.
At the time of her grandson's birth, a grandmother deposits $2000 in an account that pays 6.5% compounded monthly. What will be the value of the account at the child's twenty-first birthday, assuming that no other deposits or withdrawals are made during this period?
Answer:
$41, 863. 50
Step-by-step explanation:
$2000 - 6.5% = $1,993.50
$1,993.50 x 21 = $41, 863. 50

There are 7 girls and 3 boys in a class. Two students are to be
randomly chosen for a special project. What is the probability of
selecting a boy and a girl?
Answer:
7/15 is the probability of selecting a boy and a girl.
Step-by-step explanation:
Combination = nCr = n!/((n-r)!r!)
((7C1)(3C1))/(10C2)
= (7*3)/45
=21/45 = 7/15 the probability of selecting a boy and a girl.

(a) What is 0. 36 expressed as a fraction in simplest form?
(b) What is 0.36 expressed as a fraction in simplest form?
(c) What is 0.36 expressed as a fraction in simplest form?
Answer:
9/25
Step-by-step explanation:
3/10 + 6/100
3 is in the tenth place and 6 is in the hundredth place
rewrite the fractions as something over 100
so multiply the fraction 3/10 by 100; both numerator and denominator
this equals to 30/100 + 6/100
30 + 6 = 36/100
this can be simplified further by dividing 36 by 4 and dividing 100 by 4
this is equal to 9/25

6. Barbara has $750 to deposit into two different savings accounts.
• Barbara will deposit $350 into accountl, which earns 4.5 % annual simple interest.
• She will deposit $400 into Account II, which earns 4 % % interest compounded annually.
Barbara will not make any additional deposits or withdrawals. Which amount is closest to
the sum of the balance of Account I and account II at the end of 3 years?
9514 1404 393
Answer:
(d) $850.45
Step-by-step explanation:
The balance in account I is given by ...
A = P(1 +rt) . . . . principal P invested at annual rate r for t years
A = 350(1 +0.045×3) = 397.25
__
The balance in account II is given by ...
A = P(1 +r)^t
A = 400(1 +0.0425)^3 ≈ 453.20
__
The total amount in the two accounts is
$397.25 +453.20 = $850.45

Find P (Horse Female) Hint: P(A and B)

=========================================================
Explanation:
The vertical bar means "given", so saying "P(Horse | Female)" means "The probability of selecting a horse given the animal is female". Since we know the animal is female, we focus only on the second column.
There are 2 female horses out of 26 female animals total. Therefore, the probability we want is 2/26 = 1/13
Side note: The hint your teacher provides is also another route you can take, but I find it's a bit more complicated in my opinion.
P (Horse | Female) = 1/13
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes,
n(S) is the total number of events in the sample space.
What is conditional probability?"It is the probability of an event occurring given that another event has already occurred."
Formula for conditional probability:The probability of event A occurring given that event B has already occurred is,
P(A|B) = P(A ∩ B)/P(B)
where, P(A ∩ B) the joint probability of events A and B
For given example,
We need to find P (Horse | Female)
From given table we can observe that there are 40 animals on farm.
⇒ n(S) = 40
First we find the probability of female animals on farm.
⇒ number of female animals = 26
Using the formula of probability,
⇒ P(Female) = n(Female)/n(S)
⇒ P(Female) = 26/40
First we find the probability of female horse [P(Horse and Female)] animals on farm.
⇒ n(Horse and Female) = 2
Using the formula of probability,
⇒ P(Horse and Female) = n(Horse and Female) / n(S)
⇒ P(Horse and Female) = 2/40
Using the formula of conditional probability,
⇒ P (Horse | Female) = P (Horse and Female) / P(Female)
⇒ P (Horse | Female) = (2/40) / (26/40)
⇒ P (Horse | Female) = 2/26
⇒ P (Horse | Female) = 1/13
Therefore, P (Horse | Female) = 1/13

For the function graphed above the end behavior is:
Answer:
as w → -∞, q(w)→-∞
as w → ∞, q(w)→∞
Step-by-step explanation:
The behaviour tells us how changes y as x changes.
In the left side (as w decreases) we can see that y goes down, then we can see that as w goes to negative infinity, q(w) also goes to negative infinity.
Then we can write:
as w → -∞, q(w)→-∞
In the right side (so when w increases) we can see that q(w) increases, then with the same reasoning as above we have:
as w → ∞, q(w)→∞
Notice that in both cases we only care for the end behavior, and these changes in curvature do not really matter for this kind of analysis.

Two miners are trying to push a stationary mine cart filled with gold. Miner A is exerting 25 N while miner B is exerting 20 N. However it is observed that the mine cart remained stationary despite their push. How much force does the road exert on the wheel of the cart?
a. 25 N
b. 45 N
c. Less than
45 N d. More than 25 N
Answer:
b. 45 N
Step-by-step explanation:
The sum of the forces exerted by the two miners = 25 + 20
= 45 N
Since after applying a force of 45 N by the two miners the cart remained stationary, it implies that a resistance force of at least 45 N acts against their push. Thus, the force exerted by the road could be equal to 45 N or greater than 45 N.
Probably, if the sum of the forces applied is 46 N, the cart would move. Which depends on the value of resistance force applied by the road. Thus, the appropriate answer from the given option is B.
Since the force applied on the cart equals the resistance force exerted by the road, the cart would not move.

A concrete pillar has the shape of a cylinder. It has a radius of 3 meters and a height of 5 meters. If concrete costs $108 per cubic meter, how much did the concrete cost per pillar? Using 3.14 for pie
Answer:
Given:- r - 3 Meter
h - 5 Meter
rate - 108$ Per M³
Sol:
Volume of Cylindrical Concrete Pillar= V = πr²h
V = 3.14×3×3×5 (π = 3.14)
Volume ≈ 141.37
Cost of Concrete pillar = 108$/m³
Cost = 108 × 141.37
Cost of Making Cylindrical Concrete pillar= $15,267.96

ryan rides his bicycle 5 miles in 3/4 hour. how many miles can he ride at the same rate in 1 hour? (in fractions)
Answer:
20/3
Step-by-step explanation:
If Ryan rides his bike 5 miles in 3/4 of an hour, then he rides 5/3 miles in 1/4 of a hour (divide both by 3). To get to a full hour from 1/4, you need to multiply it by 4. You must do the same for 5/3. 5/3*4 is equal to 20/3.

Answer:
36) C, 790 m²
37) D, 625 in²
Step-by-step explanation:
To find the volume of a rectangular prism, we will multiply the length, width, and height together. The dimensions of the aquarium are 22.9×7.5×4.6. Multiply these together.
22.9 · 7.5 · 4.6 = 790.05
The volume is 790.05 m². This rounds down to 790 m², so the answer is C.
----------------------------------------------------------------------------------------------------------------
For the next question, the dimensions aren't given. Instead, we need to calculate them from the sidelengths of the unit cubes. Multiply 2.5 by the number of units on the length, width, and height of the prism. So, the dimensions are 10×12.5×5. Find the product of these dimensions.
10 · 12.5 · 5 = 625
The volume is 625 in². The answer is D.
