Step-by-step explanation:
Which line is perpendicular to a line that has a slope of -1/3?
a. line MN
b. line AB
c. line EF
d. line JK
Answer:
Option (c)
Step-by-step explanation:
Slope of a line that passing through two points M(-1, 4) and N(2, -5),
[tex]m_1[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{-1-2}{4+5}[/tex]
= -([tex]\frac{3}{9}[/tex])
= -[tex]\frac{1}{3}[/tex]
To find the line perpendicular line to MN we will use the property,
[tex]m_1\times m_2=-1[/tex]
Where [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of two perpendicular lines.
Slope of line perpendicular to MN [tex](m_2)[/tex] will be,
[tex]-\frac{1}{3}\times m_2=-1[/tex]
[tex]m_2=3[/tex]
Slope of line joining two points J(-3, -4) and K(3, -2),
Slope = [tex]\frac{-4+2}{-3-3}=\frac{1}{3}[/tex]
Slope of line joining two points A(-3, 2) and B(3, 0)
Slope = [tex]\frac{2-0}{-3-3}=-\frac{1}{3}[/tex]
Slope of the line joining points E(0, -3) and F(2, 3),
Slope = [tex]\frac{-3-3}{0-2}[/tex] = 3
Therefore, line EF is perpendicular to the line MN.
Option (c) is the answer.

Andres works 20 hours per week at a part-time job. His original pay rate was $10.00 per hour, but he recently received a pay raise of x dollars per hour. His new total weekly pay, y, is represented by the equation y=20(10+x).
If Andres earned $210 last week, what was the amount of Andres' raise per hour?
Answer:
X = .5
Step-by-step explanation:
10 × 20 = 200
10.5 × 20 = 210
Explanation:
Y = 210
210 = 20(10+X)
divide both sides by 20
10.5 = 10+X
subtract 10 from both sides
.5 = X
X = .5

What is h(3) when h(x) = 3x^2-2x+13
Answer:
34
Step-by-step explanation:
you plug in the number 3 for the x variables and solve the equation.
Answer:
h(3) = 34
Step-by-step explanation:
h(3) means plug 3 into h(x) anywhere there is an x in the equation.
h(3) = 3(3)² - 2(3) + 13
h(3) = 27 - 6 + 13
h(3) = 34

what is the base 8 representation of the number 11100111
If the given number is in base 2, that means
11100111₂ = 2⁷ + 2⁶ + 2⁵ + 2² + 2 + 1
8 = 2³, and so we have
11100111₂ = 2 • (2³)² + (2³)² + 2² • 2³ + 2² + 2 + 1
11100111₂ = 3 • 8² + 4 • 8 + 7
11100111₂ = 347₈
Because 8 is the 3rd power of 2, we can also split up the given number into block of length up-to 3, then convert each block directly into base 8:
11 100 111
11₂ = 2 + 1 = 3
100₂ = 2² = 4
111₂ = 2² + 2 + 1 = 7
so again we get 347₈.

Which of the following is not true about reflections
Answer:
what are the options like A B C or D
Two angles are supplementary. The measure of the smaller angle is four more than one third the measure of the larger angle. The measure of the larger angle is
Answer:
132
Step-by-step explanation:
2 Angles are supplementary:
x + y = 180
The smaller angle is four more than one third of other:
y = 1/3x + 4
Plug in y into the original equation:
x + 1/3x + 4 = 180
Solve the equation:
4/3x = 176
x = 176 * 3/4
x = 132
y = 48
x is the larger angle so 132 is the answer
The measure of smaller and larger angles will be 48 degrees and 132 degrees, respectively.
Given information:
The two angles are supplementary. Let them be x (larger) and y (smaller).
The measure of the smaller angle is four more than one-third the measure of the larger angle.
The above condition can be written as,
[tex]y=4+\dfrac{ x}{3}[/tex]
Supplementary angles are the angles whose sum of measure is equal to 180 degrees.
So, [tex]x+y=180[/tex]
Solve the above two equations as,
[tex]x+y=180\\x+(4+\dfrac{ x}{3})=180\\\dfrac{4x}{3}=176\\x=176\times \dfrac{3}{4}\\x=132\\y=48[/tex]
Therefore, the measure of smaller and larger angles will be 48 degrees and 132 degrees, respectively.

Military radar and missile detection systems are designed to warn a country of an enemy attack. A reliability question is whether a detection system will be able to identify an attack and issue a warning. Assume that a particular detection system has a probability of detecting a missile attack. Use the binomial probability distribution to answer the following questions. a. What is the probability that a single detection system will detect an attack? (to 2 decimals) b. If two detection systems are installed in the same area and operate independently, what is the probability that at least one of the systems will detect the attack? (to 4 decimals) c. If three systems are installed, what is the probability that at least one of the systems will detect the attack? (to 4 decimals) d. Would you recommend that multiple detection systems be used? - Select your answer -
Answer:
(a) 0.90
(b) 0.99
(c) 0.999
(d) Yes
Step-by-step explanation:
A particular detection system has a 0.90 probability of detecting a missile attack.
Let X = number of detection system that detects a missile attack.
The random variable X follows a Binomial distribution with probability of success as, p = 0.90.
(a)
Compute the probability that a single detection system will detect an attack as follows:
[tex]P(X=1)={1\choose 1}(0.90)^{1}(1-0.90)^{1-1}\\=1\times 0.90\times 1\\=0.90[/tex]
(b)
Compute the probability that at least one of the two systems will detect the attack as follows:
[tex]P(X\geq 1)=1-P(X<1)\\=1-P(X=0)\\=1-{2\choose 0}(0.90)^{0}(1-0.90)^{2-0}\\=1-0.01\\=0.99[/tex]
(c)
Compute the probability that at least one of the three systems will detect the attack as follows:
[tex]P(X\geq 1)=1-P(X<1)\\=1-P(X=0)\\=1-{3\choose 0}(0.90)^{0}(1-0.90)^{3-0}\\=1-0.001\\=0.999[/tex]
(d)
On using only one system the probability that a single detection system will detect an attack is 0.90.
On using two systems the probability that at least one of the two systems detecting the attack is 0.99.
And on using three systems the probability that at least one of the three systems detecting the attack is 0.999.
So as the number of system is increasing the probability of detecting the attack is getting closer to 1.
Thus, it would be wise to recommend that multiple detection systems be used.

What can teachers do to alleviate statistics anxiety in their students? To explore this question, statistics anxiety for students in two classes was compared. In one class, the instructor lectured in a formal manner, including dressing formally. In the other, the instructor was less formal, dressed informally, was more personal, used humor, and called on students by their first names. Anxiety was measured using a questionnaire. Higher scores indicate a greater level of anxiety. The mean anxiety score for students in the formal lecture class was 25.40 . In the informal class, the mean was 20.41 . Classify 25.40 and 20.41 as parameters or statistics.
Answer: Statistic
Step-by-step explanation: The difference between a parameter and statistic lies in the set of observation from which either quantity is derived. The parameter represents numerical values which are derived by examining or considering an entire population while the statistic is used to define numerical quantities derived from subset of the population called the sample. In the scenario described above, the population of interest would be the entire population of student and hence statistical derivations made would be called parameters. However, the scenario only experimented using student from two different classes which is a subset of the entire population of student. Hence, the obtained mean values of 25.40 and 20.41 for students in the formal and informal classes are categorized as statistic.

subtract 7 9/16 - 4 2/4
Answer:
3.0625 or 3 1/16
Step-by-step explanation:
So first Im just gonna subtract 7 - 4. (3)
So we multiply 9 by 4, and get 36.
Then we multiply 2 by 16, and get 32.
Next we give both terms new denominators -- 16 × 4 = 64.
Which yknow = 36/64 and 32/64.
Since our denominators match, we can subtract the numerators.
36 − 32 = 4 So it is 4/64..
Now we want to simplify so we divided by 2.
2/32 and 1/16
And we cant simplify It anymore because 2 is larger than 1.
So its 1/16th!! :D
