What is the equation of the given line in slope-intercept form?
A. Y = 3x - 2
B. Y = -1/3x + 2
C. Y = -3x + 2
D. Y = 3x + 2
Answer:
C
Step-by-step explanation:
slope intercept is y=mx+b
The y-intercept is at 2 so b=2.
The slope is rise/run, equaling -3
so y= -3x+2

Answer:
an = 148 + 48
Step-by-step explanation:
Answer:
aₙ = 12n + 88Step-by-step explanation:
Given sequence:
100, 112, 124, 136, 148, ...This is an AP with the first term of a₁ = 100 and common difference of d = 12.
Formula for nth term is:
aₙ = a₁ + (n - 1)d aₙ = 100 + 12(n - 1) = 100 + 12n - 12 = 12n + 88uppose a large telephone manufacturer has a problem with excessive customer complaints and consequent returns of the phones for repair or replacement.

Answer:
The answer is "294.2075".
Step-by-step explanation:
Given:
[tex]\hat{p} = 0.5 \\\\1 - \hat{p} = 1 - 0.5 = 0.5\\\\E = 4\% = 0.04\\\\[/tex]
At [tex]83\%[/tex] confidence level the z is ,
[tex]\alpha = 1 - 83\% = 1 - 0.83 = 0.17\\\\\frac{\alpha}{2} = \frac{0.17}{2} = 0.085\\\\Z_{\frac{\alpha}{2}} = Z_{0.085} = 1.3722\\\\n = (\frac{Z_{\frac{\alpha}{2}}}{E})^2 \times \hat{p} \times (1 - \hat{p})\\\\[/tex]
[tex]= (\frac{1.3722}{0.04})^2 \times 0.5 \times 0.5\\\\= (34.305)^2 \times 0.5 \times 0.5\\\\= 1,176.83 \times 0.5 \times 0.5\\\\= 1,176.83 \times 0.25\\\\=294.2075[/tex]

Answer:
In Data Set A mean , standard deviation are better measure of center as they give more information about the center of data.
In Data Set B mean , standard deviation are better measure of center as they give more information about thecenter of data.
Step-by-step explanation:
Data Set A Data Set B
1 3
3 5
3 5
2 4
4 6
0 1
4 6
3 6
3 6
5 6
2 5
Mean of Set A= 1+3+3+2+4+0+4+3+3+5+2/ 11= 30/11= 2.7272
Median of Set A= 0,1,2,2,3,3 ,3,3,4,4,5
Median ( the middle value)=3
Mode( the repeated value)= 3
Quartiles
1st Quartile= n/4 value= 30/4= 7.5 which lies between 4th and 5th value
3rd quartile= 3n/4= 90/4= 22.5 which lies between 10 th and 11th value
Range= highest value- lowest value= 5-0=5
Standard Deviation = 1.354
In this mean ,median, mode and standard deviation are better measure of center as they give more information about the data.
The range and quartiles are better measure of spread.
Mean of Set B= 3+5+5+4+6+1+6+6+6+6+5/11=53/11=4.81818
Median of Set B= 1,3,4,5,5,5,6,6,6,6,6
Median ( the middle value)= 5
Mode ( the repeated value)= 6
Quartiles
1st Quartile= n/4 value= 53/4= 13.25 which lies between 4th and 5th value
3rd quartile= 3n/4= 159/4= 39.75 which lies between 9 th and 10 th value
Range= highest value- lowest value=6-1= 5
Standard Deviation= 1.5266
In this mean , standard deviation are better measure of center as they give more information about the data.
The median mode quartiles and range are better measure of spread.
A smaller standard deviation indicates that most of the observations are close to the mean while a large value implies that the observations are scattered widely about the mean.
The quartiles must be having values near 25% and 75% of the data.
The center gives a value which is located around the center
Mean: It gives the average value.
Median:It is the middle value when data is ordered from least to greatest.
The spread gives the value showing where the data may variate.
Range: Total spread is given by the range.
Standard deviation: How far a data point is from the mean.

Answer:
Hello a value is missing in your question below is the value
samples of n = 10
answer : 24.63 < μ < 25.370
Step-by-step explanation:
Given :
Sample size = n = 10
Z∝/2 = Z0.0256 = 1.95
next calculate for margin of error
E = Z∝/2 * ( 0.6 / / [tex]\sqrt{10}[/tex] )
= 0.370
therefore at 94.87% confidence interval the estimated population mean is
x - 0.370 < μ < x + 0.370
25 - 0.370 < μ < 25 + 0.370
24.63 < μ < 25.370

A plumber charges a customer a one-time service fee of $79, $62 per hour for labor, and a surcharge of $15 per hour due to the call being an emergency.
Write an expression to represent the total charges for the plumber in two different ways. Let h represent the number of hours the job takes.
Answer:
As a plumber charges a customer a one-time service fee of $ 79, $ 62 per hour for labor, and a surcharge of $ 15 per hour due to the call being an emergency, to write an expression to represent the total charges for the plumber in two different ways, with H representing the number of hours the job takes, the following equations should be formulated:
Option 1:
Fixed amount + amount per hour multiplied by the number of hours + emergency amount multiplied by the number of hours = X
79 + 62H + 15H = X
Option 2:
Fixed amount + sum of emergency amount and the amount per hour multiplied by the number of hours = X
79 + ((62 + 15) x H) = X

Answer:
a. 5.53
b. 1.078
c. 0.126
d. 0.109
e. 0.549
f. 0.834
g. 0.451
Step-by-step explanation:
The percentage of the flights that arrive on time, P(x) = 79%
The number of flights in the sample, n = 7 flights
a. The mean of the probability distribution, μ = ∑x·P(x)
Therefore, we have; μₓ = n·p
μₓ = 7 × 79/100 = 5.53
b. The standard deviation, σₓ = √(n·p·(1 - p))
∴ σₓ = √(7 × 0.79 × (1 - 0.79)) ≈ 1.078
c. We have;
p = 0.79
q = 1 - p = 1 - 0.79 = 0.21
By binomial probability distribution formula, we have;
The probability of exactly four, P(Exactly 4) = ₇C₄·p⁴·q³
P(Exactly 4) = 35 × 0.79⁴×0.21³ ≈ 0.12625
d. The probability of less than 4 is given as follows;
P(Less than 4) = ₇C₀·p⁰·q⁷ + ₇C₁·p¹·q⁶ + ₇C₂·p²·q⁵ + ₇C₃·p³·q⁴
∴ P(Less than 4) = 1×0.79^0 * 0.21^7 + 7 * 0.79^1 × 0.21^6 + 21*0.79^2*0.29^5+ 85×0.79^3*0.21^4 ≈ 0.109
The probability of less than 4 is ≈ 0.109
e. The probability that more than 5 is given as follows;
P(More than 5) = ₇C₆·p⁶·q¹ + ₇C₇·p⁷·q⁰
7×0.79^6 * 0.21 + 1 * 0.79^7 × 0.21^0 ≈ 0.549
f. The probability that at least 5 of the flight were on time is given as follows;
P(At least 5) = ₇C₅·p⁵·q² + ₇C₆·p⁶·q¹ + ₇C₇·p⁷·q⁰
∴ P(At least 5) = 21×0.79^5 * 0.21^2 + 7×0.79^6 * 0.21 + 1 * 0.79^7 × 0.21^0 ≈ 0.834
g. For the probability that no more than 5 of the flights were on time, e have;
P(At most 5) = 1 - P(More than 5)
∴ P(At most 5) = 1 - 0.549 ≈ 0.451.
The volume of the polyhedron is ______ cm3.
Answer:
133.07 cm^3
Step-by-step explanation:
the polyhedron is a cone
volume of a cone =n r^2(h/3)
n = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
Radius = 5/2 = 2.5 in
h = height
(2.5^2 x 8) x 1/3 x 22/7 = 52.39 in^3
we need to convert inches to cm
1 in = 2.54 cm
2.54 x 52.39 = 133.07 cm^3

Answer:
Step-by-step explanation:
If m∠A + m∠B = m∠B + m∠C, subtract m∠B from both sides [ subtraction property of equality ].
We get that m∠A = m∠C and by the symmetric property of equality, m∠C = m∠A
