Suppose, 10 students have been selected for the prestigious Sir Abed Scholarship for
their excellent performances in extracurricular activities and academic results. Let’s say,
there are 4 types of award: A (100% +), B (100%), C (97%) and D (95%) . Also, a
student has an equal chance of getting any of these 4 scholarships. What is the
probability that exactly 4 of the 10 students get A and 3 students get C?
Answer:
0.1459, 0.2503
Step-by-step explanation:
Probability of getting exactly 4 A out of 10,
P(X==4) = 10C4 (1/4)^4 (3/4)^6
=0.1459
Probability of getting exactly 3 C out of 10,
P(X==3) = 10C3 (1/4)^3 (3/4)^9
=0.2503

The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 59 and a standard deviation of 3. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 59 and 62
Answer:
About 34%
Step-by-step explanation:
Given that :
Mean, m = 59 ; Standard deviation, s = 3
Bulb replacement numbering between 59 and 62
For, x = 59
Zscore = (x - m) / s
Z = (59 - 59) / 3 = 0
For x = 62
Z = (62 - 59) / 3 = 1
P(Z < 1) - P(Z < 0)
0.84134 - 0.5
= 0.34134
About 34%

9514 1404 393
Answer:
x = 36
Step-by-step explanation:
The second ratio is 3 times the first.
15 : 12 = 45 : 36 = 45 : x

In ΔEFG, g = 53 inches, e = 65 inches and ∠F=117°. Find the area of ΔEFG, to the nearest square inch.
Answer:
[tex]Area \approx 1535\ in^2[/tex]
Step-by-step explanation:
Given
[tex]g = 53[/tex]
[tex]e =65[/tex]
[tex]F = 117[/tex]
Required
Determine the area
The area is calculated as:
[tex]Area = \frac{1}{2}absinC[/tex]
In this case, it is:
[tex]Area = \frac{1}{2}egsinF[/tex]
So:
[tex]Area = \frac{1}{2} * 65 * 53 * sin(117)[/tex]
[tex]Area = \frac{1}{2} * 65 * 53 * 0.8910[/tex]
[tex]Area = 1534.7475[/tex]
[tex]Area \approx 1535\ in^2[/tex]

One angle of a parallelogram measures 65 degrees. what is the measure of the angle opposite it
Answer:
[tex]65\textdegree[/tex]
Step-by-step explanation:
Opposite angles of a parallelogram are congruent and thus have the same measure, so if one angle of a parallelogram measures [tex]65\textdegree[/tex], then the angle opposite it will also have the same measure of [tex]\bold6\bold5\textdegree[/tex]. Hope this helps!
Using the graph below, what would the input (x-value) need to be for an output (y value) of 1?
Answer:
X = 2
Y = 1
The graph intersects at the exact point of (2,1)
The value of x or the input value is 2 for which the output or the value of y is 1.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have a graph of a line shown in the picture
As we can see the line passes through the points (3, 3) and (0, -3)
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The equation of the line passes through the points:
( y + 3) = (-3-3)/(0-3)[x - 0]
y + 3 = 2x
y = 2x - 3
Plug y = 1
1 = 2x - 3
2x = 3 + 1
2x = 4
x = 4/2
x = 2
Thus, the value of x or the input value is 2 for which the output or the value of y is 1.

You want to estimate the percentage of adults who believe that passwords should be replaced with biometric security (such as fingerprints). How many randomly selected adults must you survey? Assume that you want to be % confident that the sample percentage is within percentage of the true population percentage. Complete parts (a) through (c) below.
a. Assume that nothing is known about the percentage of adults who believe that passwords should be replaced with biometric security.
b. Assume that a prior survey suggests that about 53 % of adults believe that biometric security should replace passwords.
c. Does the additional survey information from part (b) have much of an effect on the sample size that is required?
The additional survey information from part (b) causes the required sample size to change by ______10%. Based on this, the additional survey information causes ________in the sample size that is required.
Answer:
Step-by-step explanation:
From the given data;
Suppose the level of significance [tex]\alpha = 0.99[/tex]
∴
[tex]\alpha = 1 - C.I[/tex]
[tex]\alpha = 1 - 0.99[/tex]
[tex]= 0.01[/tex]
[tex]\text{Critical Value} \ \ Z_{\alpha/2}= Z_{0.01/2}} \\ \\ = 2.576[/tex]
This shows that 99% of the area under the standard normal curve falls within 2.576 S.D of the mean.
(a)
Using the knowledge of M.O.E (margin of error); we can make "n" the subject and have a derived formula:
[tex]n = \hat p (1- \hat p ) (\dfrac{Z}{E})^2[/tex]
[tex]n = 0.5 (1- 0.5 ) (\dfrac{2.576}{0.028})^2[/tex]
[tex]n = 0.5 (0.5 ) (8464)[/tex]
[tex]\mathbf{n = 2116}[/tex]
(b)
Suppose 53% of the adult are involved since it is not given, Then:
[tex]n = \hat p (1- \hat p ) (\dfrac{Z}{E})^2[/tex]
[tex]n = 0.53 (1- 0.53 ) (\dfrac{2.576}{0.028})^2[/tex]
[tex]n = 0.53 (0.47) (8464)[/tex]
[tex]\mathbf{n = 2109}[/tex]
(c)
Here; we realize that the additional information brings about a change by less than 10%. Hence, the additional information had NO significant change in the required sample.
Reshay asked 30 sixth-graders if they

responded that they own dogs. If Reshay asks all
of the 270 sixth-graders at his school the same
question, about how any of them can be expected
to say they own dogs?
A. 180
B. 200
C. 150
D. 100
Answer:
180
Step-by-step explanation:
20/30 said they owned dogs, so 2/3 of the people surveyed own dogs
2/3 of 270 is 180
