Over the last three evenings, Elsa received a total of 110 phone calls at the call center. The first evening, she received 10 fewer calls than the third
evening. The second evening, she received 4 times as many calls as the third evening. How many phone calls did she receive each evening?
Answer:
first evening, 10 calls, second evening 80 calls, third evening, 20 calls.
Step-by-step explanation:
if the number of calls received during the first evening is X, then the number of calls received during the third evening is X+10 as the third evening received 10 more calls than first evening. The second evening received 4 times of third so 4X+10. Add them up together and put them equal to 110.
X+10+X+4X+40=110
6X+50=110
6X=110-50
6X=60
X=10
First evening, 10 calls,
second evening 80 calls; 4X+40, 4(10)+40=80
third evening 20 calls; X+10, (10)+10=20

In a basketball skills competition, Corson successfully made 5 of 7 shots and Charleigh made 3 of 5
shots
Determine which player had a better performance at the skills competition.
Answer:
Corson had a better performance at the skills competition.
Step-by-step explanation:
In order to determine which player had a better performance at the skills competition, we need to find the percentage performance of both the players.
Therefore,
Corson's percentage performance
[tex] =\frac{5}{7}\times 100= 71.43%[/tex]
Charleigh's percentage performance
[tex] =\frac{3}{5}\times 100= 60%[/tex]
[tex] \because [/tex] Corson's percentage performance > Charleigh's percentage performance
So, Corson had a better performance at the skills competition.
A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associate is $600 and the daily rate for each partner is $1100. The law firm assigned a total of 10 lawyers to the case and was able to charge the client $8000 per day for these lawyers' services. Determine the number of associates assigned to the case and the number of partners assigned to the case.
There were ____associates assigned to the case and ____
partners assigned to the case.
Answer: x = 7
Thus 7 associates and 10 partners were assigned
Step-by-step explanation:
7 associates and 10 partners were assigned
Let "x" be the number of associates assigned to
case
Let "y" be the number of partners assigned to the case
The law firm assigned a total of 17 lawyers to the case
Therefore,
x + y = 17
x = 17 - y --------- eqn 1
daily rate charged to the client for each associate is $800
daily rate for each partner is $1800
They was able to charge the client $23600 per day for these lawyers' services
Therefore,
800x + 1800y = 23600 ------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 1 in eqn 2
800(17 - y) + 1800y = 23600
13600 - 800y + 1800y = 23600
1000y = 23600 - 13600
1000y = 10000
Divide both sides by 1000
y = 10
Substitute y = 10 in eqn 1
x = 17 - 10
x = 7
Thus 7 associates and 10 partners were assigned

Given the sequence [tex]c_n[/tex] defined recursively below, find [tex]c_5[/tex].
[tex]c_1 =4[/tex]
[tex]c_2 = 2[/tex]
[tex]c_n = 3c_{n-1}+2c_{n-2}-2[/tex]
Hello!
[tex]\large\boxed{c_{5} = 136}[/tex]
We can begin by solving for c₃ given the equations:
c₃ = 3c₂ + 2c₁ - 2
c₃ = 3(2) + 2(4) - 2
Simplify:
c₃ = 6 + 8 - 2 = 12
We can now find the subsequent terms:
c₄ = 3(12) + 2(2) - 2 = 38
c₅ = 3(38) + 2(12) - 2 = 136
Now we have to,
find the required value of c₅.
Given that,
→ c₁ = 4
→ c₂ = 2
→ [tex] \sf {c_n = 3c_{n-1}+2c_{n-2}-2}[/tex]
Let's solve c₃ first,
→ 3c₂ + 2c₁ - 2
→ 3(2) + 2(4) - 2
→ 6 + 8 - 2 = 12
Then the value of c₃ is
→ [c₃ = 12]
Then find the value of c₄,
→ c₄ = 3(12) + 2(2) - 2
→ c₄ = {36 + 4} - 2
→ c₄ = 40 - 2
→ [c₄ = 38]
Next we can solve for c₅,
→ c₅ = 3(38) + 2(12) - 2
→ c₅ = {114 + 24} - 2
→ c₅ = 138 - 2
→ [c₅ = 136]
Hence, the value of c₅ is 136.

Step-by-step explanation:
hello I need help on the 4 questions please help thank you:D
Step-by-step explanation:
1. simple interest
I= p × r × t
I = 1050 × 4.5 × 2
I = $9450
2. principal
p = I/(rt)
p= 22.50/ (3× 3)
p = 22.50/9
p = $2.5
3. simple interest
I= p × r × t
I = 500 × 5 × 3
I = $7500
4. time
first convert r to decimal
r= r/100, r= 3.5 / 100
r= 0.035
t = i/(pr)
t = 43.75/ (2500× 0.035)
t = 43.75/ 87.5
t = 0.5 year or 6 months

A Pharmaceutical Company uses a machine to pour cold medicine into bottles in such a way that the s. d. of the weights is 0.15 oz. A new machine is tested on 68 bottles and the s. d. for this sample is 0.12 oz. The Dayton Machine company, which manufactures the new machine claims that it fills bottle with a lower variation. At a 1% level of significance test the claim made by the Dayton Machine Company. For all test of hypothesis problems,
1. Set up the null and alternate hypothesis
2. Calculate the test statistic.
3. find the critical value(s) or P value.
4. Make a decision.
5. Write the conclusion in terms of the problem.
Answer:
1) H0 : σ₁ ²≥ σ₂²; Ha: σ₁² < σ₂²
2) χ²= 43.52
3) The critical region is χ²≤ 5.23
4) Reject the alternate hypothesis.
5) We conclude that the alternate hypothesis is false and accept the null hypothesis.
Step-by-step explanation:
The claim is that it fills bottle with a lower variation which is the alternate hypothesis
1) Ha: σ₁² < σ₂² where σ₁² is the variation of the new machine and σ₂² is the variation of the old machine.
The null hypothesis is opposite of alternate hypothesis H0 : σ₁ ²≥ σ₂²
2) The test statistic is χ²= ns²/σ ² which under H0 has χ² distribution with n-1 degrees of freedom assuming the population is normal.
The calculated χ²= ns²/σ ² = 68( 0.12)²/ (0.15)²=0.9792/0.0225= 43.52
3) The critical region is entirely in the left tail. χ²≤χ²( 0.99)(15)= 5.23
4) The alternate hypothesis is false hence reject it.
5) The calculated χ²= 43.52 does not lie in the critical region χ²≤ 5.23 therefore H0 is accepted and concluded that new machine does not fill bottles with a lower variation.

Which expression is equivalent to 36x2 − 100? a. 4(3x − 5)(3x − 5)
b. 4(3x + 5)(3x − 5)
c. 2(9x − 25)(9x − 25) d. 2(9x + 25)(9x − 25)
Answer:
b. 4(3x + 5)(3x - 5)
Step-by-step explanation:
Recall difference of squares general formula as a² - b² = (a+b)(a-b)
Looking at the question we have 36x² - 100
Looking at the given answer choices we see there is some factor multiplied through the difference of squares, so we pull out the greatest common factor from the question to get 36x² - 100 = 4(9x² - 25). Now apply difference of squares where a² = 9x² and b² = 25 to get a = 3x and b = 5. Now the equation becomes b. 4(3x + 5)(3x - 5)

Step-by-step explanation:
Write a new function that represents a transformation to the parent function if the new function shifts right 5 units and up 3 units.
Answer:
Let's define two transformations.
Vertical translation.
If we have a function f(x), a vertical translation of N untis is written as:
g(x) = f(x) + N
If N is positive, then the translation is upwards
If N is negative, then the translation is downwards.
Horizontal translation.
If we have a function f(x), a horizontal translation of N units is written as:
g(x) = f(x - N)
if N is positive, then the translation is to the right
If N is negative, then the translation is to the left.
Now we have a function g(x) that is a transformation of a parent function f(x) (we actually do not know which parent function, so i assume f(x) = x^2) such that we have a shift right 5 units and up 3 units.
Then:
g(x) = f(x - 5) + 3
and again, using f(x) = x^2
g(x) = (x - 5)^2 + 3

Have a nice day
Answer:
Remember that the Pythagorean's theorem says that:
For a triangle rectangle with hypotenuse H and catheti A and B:
H^2 = A^2 + B^2
Here we also need to remember that the area of a square of side length L is:
area = L^2
Now let's solve this.
First, we start with two squares, one of side length a and the other of side length b.
Such that the complete area in the first image is:
area = a^2 + b^2
Now we draw two triangle rectangles with catheti a and b, and with hypotenuse c.
in step 3, we rotate those triangles in order to make a larger square, with side length c, with an area equal to:
area = c^2
Notice that we never added more shapes, so the area of the image did not change in all this process, then the initial area must be equal to the final area:
a^2 + b^2 = area = c^2
a^2 + b^2 = c^2
And remember that a and b are the catheti of the triangles, and c is the hypotenuse, then this is the Pythagorean's theorem.
The Gotemba walking trail up Mount Fuji is about 9km long. Walkers need to return from the 18km walk by 8pm. Toshi estimates that he can walk up the mountain at 1.5km/h on average, and down at twice that speed. These speeds take into account meal breaks and rest times. Using Toshi's estimated speeds, what is the latest time he can begin his walk so that he can return by 8pm?
Answer:
Toshi must begin his walk at 11:00 AM in order that he can return by 8:00 PM.
Step-by-step explanation:
Since the Gotemba walking trail up Mount Fuji is about 9km long, and walkers need to return from the 18km walk by 8pm, if Toshi estimates that he can walk up the mountain at 1.5km / h on average, and down at twice that speed , these speeds taking into account meal breaks and rest times, to determine what is the latest time he can begin his walk so that he can return by 8pm the following calculation must be performed:
Climb: 1.5 km / h
Descent: 2 x 1.5 km / h = 3 km / h
Climb: 9 km / 1.5 km / h = 6 hours
Descent: 9km / 3 km / h = 3 hours
Total: 9 hours
8 PM = 20:00
20:00 - 09:00 = 11:00
Thus, Toshi must begin his walk at 11:00 AM in order that he can return by 8:00 PM.
