Answer:
16 seconds
Step-by-step explanation:
You basically have to do all numbers times 2
The required time the electric clock would take to sound 6 times is 16 seconds at 6:00.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
It takes 8 seconds for an electric clock to sound 3 times, so it takes,
= 8 / 3 = 2.67 seconds to sound once.
Therefore, the time it would take
= 2.67 × 6
= 16 seconds
Thus, the required time the electric clock would take to sound 6 times is 16 seconds at 6:00.

Step-by-step explanation:
Consider a small ferry that can accommodate cars and buses. The toll for cars is $3, and the toll for buses is $10. Let X and Y denote the number of cars and buses, respectively, carried on a single trip. Suppose the joint distribution of X and Y is as given in the table below.
y
p(x,y) 0 1 2
x 0 0.025 0.015 0.010
1 0.050 0.030 0.020
2 0.115 0.075 0.050
3 0.150 0.090 0.060
4 0.100 0.060 0.040
Compute the expected revenue from a single trip. (Round your answer to two decimal places.)
Answer:
Expected revenue from the single trip is $ 13.14
Step-by-step explanation:
y
p(x,y) 0 1 2 g(x)
x 0 0.025 0.015 0.010 0.05
1 0.050 0.030 0.020 0.1

3 0.150 0.090 0.060 0.3
4 0.100 0.060 0.040 0.2
h(y) 0.325 0.27 0.18
E (x+Y) = E(X) +E(Y)
E(X)= ∑ xi g(x)i
= ( 0*0.05) + (1*0.1) + (2* 0.24) + (3*0.3) + (4*0.2)
= 0 + 0.1+ 0.48 + 0.9+0.8
=2.28
E(Y)= ∑yi h(y)
= (0* 0.325) + (1*0.27) + (2*0.18)
= 0 +0.27+ 0.36
= 0.63
E (x+Y) = E(X) +E(Y)
= 2.28 + 0.63
= 2.91
But the equation is 3x+ 10y
E(3x+ 10y)= 3E(x) + 10 E(y)
= 3(2.28) + 10 (0.63)
= 6.84 +6.3
= 13.14

Answer:
$83.50
Step-by-step explanation:
8.75 x 3 = 26.25
15.50 x 1 = 15.50
26.26 + 15.50 = 41.75
41.75 x 2 = 83.50
Write the equation of the line in slope-intercept form that goes through the points: (2, 4) and (7, -1) *
Answer:
1. slanting upward because the slope is positive one.
2. A: 3/4 B: 4/-3
3. A: 3 B: y=3x-10
1. (-2-7)/(-4-5) = -9/-9 = 1
2. A: (7-4)/(7-3) = 3/4
B: (8-0)/(-6-0) = 8/-6 = 4/-3
3. find the slope first so (4-1)/(2-1)= 3/1. then you plug in point C to find the y intercept so y=mx+b would be 2=3(4)+b which makes it so b is -10. the new equation would be y=3x-10
Step-by-step explanation:
A line goes through (1, 8) and has a slope of 1
Answer: If your looking for the slope Intercept form, the answer is y=1x+7

A ____ variable is a value found from the value of another variable.
Patty’s dog Socks eats 15 ounces of dry dog food a day. How many days will a 30-pound bag last? Is this more or less than a month? Explain. Remember, there are 16 ounces in a pound.
Answer: 32 days. This is more than a month.
Step-by-step explanation:
First, convert the 30 pound bag into ounces. To do this you just need to multiply 30 by 16. You will get 480 ounces (so one bag has 480 ounces of food in it. Then, just divide that by the ounces eaten by Socks in a day. 480/15 is 32. So one bag of food lasts 32 days. At the most, one month can have 31 days in it so this bag will last for more than a month. Hope this helps!
g Explain the difference between explanatory and response variables. Is it important to distinguish between the two in linear regression
Answer: See explanation
Step-by-step explanation:
The response variable is the variable that the researcher is interested in. It is what the experiment really focuses on.
An explanatory variable is the variable that is being manipulated by the researcher and it explains the variations that may occur to the response variable.
It should also be noted that it is important to distinguish between the response variable and the explanatory variable in a linear regression.

52% of all Americans are home owners. If 45 Americans are randomly selected, find the probability that a. Exactly 21 of them are are home owners. b. At most 24 of them are are home owners. c. At least 23 of them are home owners. d. Between 20 and 24 (including 20 and 24) of them are home owners.
Answer:
0.0918 ; 0.6277 ; 0.6064; 0.5055
Step-by-step explanation:
Given that :
Proportion of home owners : p = 0.52
Number of trials = 45
Using binomial distribution formula :
P(x =x) = nCr * p^x * (1 - p)^(n-x)
A.) probability that exactly 21 are homeowners :
P(x = 21) = 45C21 * 0.52^21 * (1 - 0.52)^(45 - 21)
P(x = 21) = 45C21 * 0.52^21 * 0.48^24
P(x = 21) = 3773655750150 * 0.52^21 * 0.48^24
P(x = 21) = 0.0918
b. At most 24 of them are are home
Using the binomial probability to save computation time.
P(x ≤ 24) = p(0) + p(1) +.... + p(24)
P(x ≤ 24) = 0.6277
C.) At least 23 of them are home owners.
P(x ≥ 23) = p(23) + p(24) +... + p(45)
P(x ≥ 23) = 0.6064
d. Between 20 and 24 (including 20 and 24) of them are home owners.
P(20 ≤ x ≤ 24) = p(20) + p(21) + p(22) + p(23) + p(24)
P(20 ≤ x ≤ 24) = 0.0711 + 0.0918 + 0.1084 + 0.1175 + 0.1167
P(20 ≤ x ≤ 24) = 0.5055

Answer: 54°
because QS bisects ∠PQR
=> m∠PQS = m∠RQS
⇔ x + 24 = 3x - 36
⇔ 2x = 60
⇔ x = 30
with x = 30, we have: m∠PQS = 30 + 24 = 54°

An insurance company charges Ted E. Bear $1400 per year for insurance on his home. The company has predicted that there is a 10% chance that Ted will make a claim on the policy of $5000. Create a probability distribution and determine what the insurance company can expect to make on this policy, on average?
Answer:
$900
Step-by-step explanation:
The given parameters are;
The amount Ted pays per year for insurance on his home = $1,400
The value of the insurance policy = $5000
The chance that Ted will make a claim on the policy = 10%
The expected value is given as follows
Incidence Probability(p) Value(v) v × p
A claim is made 0.1 $5,000 - $1,400 = -$3,600 -$360
No claim 0.9 $1,400 $1260
Expected value is $1,260 - $360 = $900
The value the insurance company can be expected to make on average on the policy is $900
