Answer:
105°
Step-by-step explanation:
The sum of all the interior angles of a triangle is equal to 180°. With that I. mind, we can write
(6x + 5) + (11x - 5) + x = 180
Collecting all similar terms, we get
18x = 180 or x = 10
They, the measure of angle Q is
Angle Q = 11x - 5 = 11(10) - 5
= 105°

If mBCD = 148°, what is m∠BCD?
74°
32°
148°
106°
Answers
Answer:
Option (1)
Step-by-step explanation:
Given : m(arc BCD) = 148°
By the property,
Inscribed angle formed by an arc measures half the measure of the arc.
m(arc BCD) = 2(m∠BCD)
148° == 2(m∠BCD)
m(∠BCD) = 74°
Therefore, Option (1) will be the correct option.

A certain component is critical to the operation of an electrical system and must be replaced immediately upon failure. If the mean lifetime of this type of component is 100 hours and its standard deviation is 30 hours, how many of these components must be in stock so that the probability that the system is in continual operation for the next 2000 hours is at least 0.95?
Answers
Answer:
Step-by-step explanation:
From the given information:
Assuming we have an integer c to represent the components in the stocks.
Thus, the needed probability can be expressed as:
[tex]P(X_1+X_2+ ........ X_c \ge 2000)[/tex]
To break this down, we have:
[tex]P(\sum X_i \ge 2000) = P \Bigg(\dfrac{\sum X_i - 100n}{\sqrt{n \ Var (X)}} \ge \dfrac{2000-100 n }{\sqrt{n \times 900}} \Bigg )[/tex]
[tex]P \Bigg(\dfrac{\sum X_i - 100n}{\sqrt{n \ Var (X)}} \ge \dfrac{2000-100 n }{\sqrt{n \times 900}} \Bigg )= P (Z \ge 0.95 ) \ \ \ because \ Z_{0.05} = -1.65 \\ \\ \\ \dfrac{2000-100 n }{\sqrt{n \times 900}} = -1.65 \\ \\ \\ \dfrac{100\ n-2000 }{\sqrt{900n}} = 1.65 \\ \\ 100 n -1.65 \sqrt{900 n }-2000 = 0[/tex]
By solving the equation:
n = 23
Thus, relating to the needed condition; n ≥ 23
The needed number of the components that should be in stock should be at least 23.

Answer:
[tex]p = 7[/tex]
Step-by-step explanation:
So the key is that a line has a measure of 180 degrees. Notice the square between the rays. That is a 90-degree angle. So let's add this up and see what's going on
[tex](5p + 2) + 90 + (7p + 4) = 180[/tex]
[tex]12p + 96 = 180[/tex]
[tex]12p = 84[/tex]
[tex]p = 7[/tex]
Answer:
p = 7
Step-by-step explanation:
From the diagram, we can see that all the angles given form a straight line, and therefore add up to 180°.
We can create an equation with what is given:
***The angle with the square marked is 90°.
5p° + 2° + 90° + 7p° + 4° = 180°
You can combine the like terms, getting:
12p° + 96° = 180°
Now, subtract 96° from both sides:
12p° = 84°
Now, divide by 12°, and get:
p = 7

If a student is selected at random, find the
probability the student is a senior given that it's
female. Round to the nearest whole percent.
[?]%
Answers
Answer:
19%Step-by-step explanation:
Total Females = 3 + 4 + 6 + 3 = 16
Number of female seniors = 3
P ( Female | senior )
number of female seniors / total female = [tex]\frac{3}{16}[/tex]
In percent,
[tex]\frac{3}{16}[/tex] · 100 = 0.1875 · 100 = 18.75%
18.75% rounded to nearest whole percent is 19%
The required probability is 3/4= 75%, the probability the student is a senior given that it's female.
What is the probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
here, we have,
We have to compute the probability,
P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.
Determine the total number of juniors. Juniors=2+6=8
Since the number of females who are junior is 6, determine the required probability.
P(Female|Junior)=6/8=3/4
Therefore, the required probability is 3/4 = 75%

A study of the career paths of hotel general managers sent questionnaires to an SRS of 230 hotels belonging to major U.S. hotel chains. There were 109 responses. The average time these 109 general managers had spent with their current company was 12.08 years. (Take it as known that the standard deviation of time with the company for all general managers is 2.7 years.) (a) Find the margin of error for an 80% confidence interval to estimate the mean time a general manager had spent with their current company: years (b) Find the margin of error for a 99% confidence interval to estimate the mean time a general manager had spent with their current company: years (c) In general, increasing the confidence level the margin of error (width) of the confidence interval. (Enter: ''DECREASES'', ''DOES NOT CHANGE'' or ''INCREASES'', without the quotes.)
Answers
Answer:
a)
The margin of error is of 0.33 years.
b)
The margin of error is of 0.67 years.
c)
INCREASES
Step-by-step explanation:
In this question, we have that:
Sample of 109 means that [tex]n = 109[/tex]
The standard deviation of time with the company for all general managers is 2.7 years, which means that [tex]\sigma = 2.7[/tex]
Question a:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.8}{2} = 0.1[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.1= 0.9[/tex], so Z = 1.28.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
So
[tex]M = 1.28\frac{2.7}{\sqrt{109}} = 0.33[/tex]
The margin of error is of 0.33 years.
Question b:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005= 0.995[/tex], so Z = 2.575. So
[tex]M = 2.575\frac{2.7}{\sqrt{109}} = 0.67[/tex]
The margin of error is of 0.67 years.
(c) In general, increasing the confidence level the margin of error (width) of the confidence interval.
We have that:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
That is, M and z are direct proportional, and since z increases when the confidence level increases, the marign of error will increase. So the answer is INCREASES.

Stewart goes out for lunch with some of his friends. The total bill comes to
$500. The friends think that since it is Stewart’s birthday, he shouldn't have to pay. They split the cost of his lunch, with each friend paying an additional
$1
a) How many people ate dinner? Including Stewart
Answers
9514 1404 393
Answer:
0 people ate dinner
23 people ate lunch
Step-by-step explanation:
If the bill is split evenly between x people, then each pays 500/x.
Splitting the bill between x-1 people means each pays 500/(x -1).
When the difference in those amounts is 1.00, we have ...
500/(x -1) -500/x = 1
500 = x(x -1)
Completing the square gives ...
500.25 = (x -0.5)²
x = 0.5 +√500.25 ≈ 22.866 ≈ 23
Check
With 22 people splitting the $500 bill, the amount each pays is ...
$500/22 ≈ $22.73
With 23 people splitting the bill, the amount each pays is ...
$500/23 ≈ $21.74
The difference is $0.99, about $1.00. This is as close as you will get with these numbers.
