The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.
Answer:
[ Because those two numbers are removed you need to reduce the number of terms to 98. ]
☆Solution☆
N=100
Mean=65
(Wrong Numbers=40,50)
Now,
Mean=Sum/No. of items
or,65=Sum/100
▪Sum=65×100=6500
After removing the unnecessary numbers,
New Sum=6500-40-50=6410
New no.of terms(N)=100-2=98
Now,
New Mean=New Sum/New N
=6410/98
=65.41

Marcia drew a plan for a rectangular piece of material that she will use for a blanket. Three of the vertices are (-2.6, -1.5), ( -2.6,3.3), and (2.7, 3.3). What are the coordinates of the fourth vertex?
Answer:
[tex](2.7,-1.5)[/tex]
Step-by-step explanation:
The points are [tex]A(-2.6,1.5), B(-2.6,3.3), C(2.7,3.3)[/tex]
The fourth vertex will can be found by the points [tex]A[/tex] and [tex]C[/tex].
The angles between the sides of a rectangle are [tex]90^{\circ}[/tex].
The [tex]x[/tex] coordinate will be the same as [tex]C[/tex] and the [tex]y[/tex] coordinate will be the same as [tex]A[/tex]. The fourth verex is [tex]D[/tex].
So, the fourth vertex of the rectangular piece will be [tex](2.7,-1.5)[/tex].

find the value of 956$ deposited for 12 years in a account paying 6% anuale interest when it is...
1 compounded quarterly
2componded anualy
Answer:
1. $1953.572. $1923.66Step-by-step explanation:
Compounded interest amount formula:
A = P(1 + r/n)^(nt)Given:
P = $956r = 6% = 0.06t = 12 yearsn = 4 and n = 11. Compounded quarterly
A = 956(1 + 0.06/4)^(4*12) = 956(1.015)^48 = 1953.572. Compounded annually
A = 956(1 + 0.06)^12 = 1923.66Answer:
Answer:
1. $1953.57
2. $1923.66
Step-by-step explanation:
Compounded interest amount formula:
A = P(1 + r/n)^(nt)
Given:
P = $956
r= 6% = 0.06
. t = 12 years
n = 4 and n = 1
1. Compounded quarterly
A = 956(1 + 0.06/4)^(4*12) = 956(1.015)^48 = 1953.57
2. Compounded annually
· A = 956(1+ 0.06)^12 = 1923.66

The attendance at the art museum at the New Year's opening was 250 people. The attendance has been increasing at a rate of 3% each month. How many people will attend by the end of a year? 1329 5825 265 356
Given:
Initially the number of people at art museum = 250
Rate of increase = 3% per month
To find:
The number of people at art museum in the end of a year.
Solution:
The general exponential growth model is:
[tex]y=a\left(1+\dfrac{r}{100}\right)^t[/tex]
Where, a is the initial value, r is the rate of increase in % and t is the time period.
We know that, 1 year = 12 months.
Putting a=250, r=3 and t=12, we get
[tex]y=250\left(1+\dfrac{3}{100}\right)^{12}[/tex]
[tex]y=250\left(1+0.03\right)^{12}[/tex]
[tex]y=250\left(1.03\right)^{12}[/tex]
[tex]y=250(1.42576)[/tex]
[tex]y=356.44[/tex]
[tex]y\approx 356[/tex]
The number of people at the end of a year is 356. Therefore, the correct option is D.

Find all solutions to the equation.
cos^2x + 2 cos x + 1 = 0 (4 points)
Answer:
cos^2x + (1+1)cos x + 1 = 0
or,cos^2x + cos x + cos x + 1 = 0
or,cos x(cos x + 1) + 1 (cos x + 1) = 0
or, (cosx + 1) + (cosx + 1) = 0
either
cosx + 1 =0 or cosx +1 =0
Members of the Video Digital club produce short videos. At the end
of each school year, the club hosts a Video Digital festival at a local
theater to show the community its top 25 videos.
Part A:
The club has realized from experience that when they don't charge
for admission, 800 people come. For every dollar they charge for
admission, 8 fewer people come. Write an inequality that they can
use to determine the price, p, in dollars that the club must charge for
at least 750 to come to the video festival
Part B: solve the inequality you wrote to in part A
Part C: explain in words what the solution to the inequality means in terms of the situation. Explain why the direction of the inequality sign in the solution makes sense.

Answer:
68
Step-by-step explanation:
the square shape on the corner means it is a right angle, which is 90 degrees
--> that means the value which comes out when you subtract 22 from 90 is the angle left, which is "a" in this case.
90-22=68
