Jamie can paint a wall in 54 minutes Together Connie and Jamie can paint the same wall in 36 minutes How long would it take Connie to paint the same wall by herself
Answer:
The answer is 108
Step-by-step explanation:
I did this for my exam got 100
Together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.
We have given that,
John can paint 1/54 of a wall in 1 minute.
James can paint 1/36 of a wall in 1 minute.
What is the formula for total wall paint in one minute?Total wall paint of both in one minute is calculated by adding the both the paint in one minute it gives us the total paint in one minute
Therefore ,total wall paint in one minute =1/54 + 1/36
So if they work together, they can both paint 1/54 + 1/36 of a wall in 1 minute.
1/54 + 1/36 = 2/108 + 3/108 = 5/108 = 0.04629.
Therefore,together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.

On the occasion of its 10-year anniversary, AJ Inc. sells lucky draw tickets. If the customers are interested in the lucky draw contest, then they have to purchase a ticket for $15. The gift could be worth $115, $215, $315, or nothing. The probability of each event is given below. What is the value of the standard deviation
Probability 0.35 0.26 0.21 0.18
Amount gained $100 $200 $300 -$15
Option;
a) $11,143
b) $106
c) $10,200
d) $147
Answer:
the standard deviation is 106
Option b) $106 is the correct Answer
Step-by-step explanation:
Given the data in the question;
let the random variable be x
x = amount gained by customers in a lucky draw contest
so
Variance (x) = [∑(x² × P(x))] - [(∑(x × P(x))²]
so
x x² p(x) x.p(x) x².p(x)
$100 10,000 0.35 35 3,500
$200 40,000 0.26 52 10,400
$300 90,000 0.21 63 18,900
-$15 225 0.18 -2.7 40.5
TOTAL 147.3 32,840.5
Variance (x) = [∑(x² × P(x))] - [(∑(x × P(x))²]
we substitute;
Variance (x) = 32,840.5 - (147.3)²
Variance (x) = 32,840.5 - 21,697.29
Variance (x) = 11,143.21
Now Standard Deviation = √variance
so, S.D = √11,143.21
S.D = 105.56 ≈ 106
Therefore, the standard deviation is 106
Option b) $106 is the correct Answer
In an urban area, 31% of dog owners pay for someone to walk their dogs. Morgan asks a random sample of 50 dog owners in this urban area if they pay for someone to walk their dog. What is the probability that more than 30% of the owners in the sample pay for someone to walk their dog?
A. 0.439
B. 0.519
C. 0.561
D. 0.586
Answer:
c 0.561
Step-by-step explanation:
did the test on edge
The probability that more than 30% of the owners in the sample pay for someone to walk their dog is option c. 0.561.
Calculation of the probability:Since 31% of dog owners pay for someone to walk their dogs. Morgan asks a random sample of 50 dog
So
= P> ( 0.30 - 0.31) / √0.31 (1 - 0.31)/ 50
= P(z > - 0.1530)
= 0.5608
= 0.561
Hence, the option c is correct.

Determine the domain of the following graph:
write an equation in slope-intercept form for the line that has a slope of 4 and passes through the point (3,24)
Answer:
y = 4x + 12
Step-by-step explanation:
y = mx + b
'm' represents slope
'b' represents the y-intercept
use the slope and the point (3,24) as your x and y inputs to find 'b'
24 = 4(3) + b
24 = 12 + b
b = 12
y = 4x + 12

The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]D = 25 + 0.3X[/tex]
The question has missing details; as what's required is not stated.
However, since it is a linear equation, possible questions could be
1. Determine the slope
2. Determine the D-intercept
3. Calculate the amount in dollars for (say) 5 miles
An equation is represented as:
[tex]D = b + mx[/tex]
Where
[tex]b = D\ intercept[/tex]
[tex]m = slope[/tex]
By comparing: [tex]D = 25 + 0.3X[/tex] to [tex]D = b + mx[/tex]
[tex]b = 25[/tex] and [tex]m = 0.3[/tex]
This means that the slope is 0.3 and the d intercept is 25
To get the amount for 5 miles, we substitute 5 for x in [tex]D = 25 + 0.3X[/tex]
[tex]D = 25 + 0.3 * 5[/tex]
[tex]D = 25 + 1.5[/tex]
[tex]D = 26.5[/tex]
The cost of 5 miles is $26

We have to given that;
The point is,
⇒ (- 3, - 3)
Now, We know that;
The rule of reflection after across the y - axis is,
⇒ (x, y) = (- x, y)
Thus, The point which is a reflection of (-3,-3) across the y-axis is,
⇒ (x, y) = (- x, y)
⇒ (-3, -3) = (- (-3), -3)
= (3, - 3)
