What's a common denominator for 1/2 and 1/14 SOMEONE PLEASE HELP IM ABOUT TO TAKE A TEST!!!!!!!!!!!
Answer: common denominator between 2 and 14 is 28 add 14 twice and you’ll get an even number now find out how many times you multiplied by two
Step-by-step explanation:
Answer: a common denominator for 1/2 would be 4 and for 1/14 it would be 28
Step-by-step explanation: to find common denominator you can either multiply or divide, but in this situation since the numerator is one you can only multiply. i chose to multiply them by 2.
1 x 2 = 2 = 2/4
2 x 2 = 4
1 x 2 = 2 = 2/28
14 x 2 = 28

Step-by-step explanation:
For a specific location in a particularly rainy city, the time a new thunderstorm begins to produce rain (first drop time) is uniformly distributed throughout the day and independent of this first drop time for the surrounding days. Given that it will rain during some period on both of the next two days, what is the probability that the first drop of rain will be felt between 9:15 AM and 2:50 PM on both days
Answer:
The required probability = 0.0541
Step-by-step explanation:
From the given information:
The probability that it will rain throughout the day is uniformly distributed & independent of the surrounding days.
Assuming that (P₁) represents the probability that it will rain between 9:15 am to 2:50 pm on day 1.
The time interval is 5 hours 35 minutes long.
= 5.583333 hours long
Thus;
P₁ = 5.583333/24
P₁ = 0.2326
Assuming that (P₂) represents the probability that it will rain between 9:15 am to 2:50 pm on day 2.
P₂ = P₁ = 0.2326
Therefore, the total probability = P₂ × P₁ (independent events)
= 0.2326 × 0.2326
= 0.05410276
≅ 0.0541

Three questions Please HELP!
At which point do the equations y=−2x+10 and y=x+4 intersect?(1 point)
(1,6)
(2,6)
(2,5)
(1,5)
2.If the two lines y1=−12x+5 and y2=2x+5 were to be graphed, what would their intersection point represent?
(1 point)
Their intersection point is the only point where different inputs into both functions yield different outputs.
Their intersection point is the only point where the same input into both functions yields different outputs.
Their intersection point is the only point where different inputs into both functions yield the same output.
Their intersection point is the only point where the same input into both functions yields the same output.
3.Given an equation y=−13x+5, explain the steps for using slope-intercept form to graph this equation.(1 point)
Use the y-intercept to plot the point (5,0). Then, using the y-intercept as a reference point, move right 3 units and up 1 unit, and plot a second point.
Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point, move left 1 unit and up 3 units, and plot a second point.

Answer:
2,6
Step-by-step explanation:
Answer:
1. (2,6)
2. C
3. B
Step-by-step explanation:
y = - 2x + 10
y = x + 4
SInce the two equation both equal y, we can said they are equal.
- 2x + 10 = x + 4
- 10 - 10
- 2x = x - 6
- x - x
- 3x = - 6
/-3 /-3
x = 2
Then we plug the x value into the equations and we will get the point that intersects y=-2x+10 and y=x+4.
- 2(2) + 10 = 2 + 4
- 4 + 10 = 6
6 = 6
This is true since both sides are equal.
The point that intersects y=-2x+10 and y=x+4 is (2,6).
2. If the two lines y1=−12x+5 and y2=2x+5 were to be graphed, what would their intersection point represent?
C) Their intersection point is the only point where different inputs into both functions yield the same output.
Ex: y=-2x+10 and y=x+4 both have the same solution which is (2,6).
3. Given an equation y=−13x+5, explain the steps for using slope-intercept form to graph this equation.
y = - 1/3x + 5
y = - 1/3(0) + 5
y = 5
Point: (0,5)
Slope: - 1/3
Rise over run (y/x) so up 3 and left 1.
B) Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point, move left 1 unit and up 3 units, and plot a second point.
The gypsy moth is a serious threat to oak and aspen trees. A state agriculture department places traps throughout the state to detect the moths. When traps are checked periodically, the mean number of moths trapped is only 0.4, but some traps have several moths. The distribution of moth counts is discrete and strongly skewed, with standard deviation 0.6. (a) What are the mean and standard deviation of the average number of moths x in 45 traps
Answer:
Mean = 0.4
Stand deviation = 0.08944
Step-by-step explanation:
1.
This question tells us that the mean of trapped moths is only 0.4
Therefore the mean = E(X) = 0.4
2.
The standard deviation of the sample mean is
= σ/√n
σ = 0.6
n = 45
When we put these values into the formula we will have:
0.6/√45
= 0.6/6.708
= 0.08944
So in conclusion, the mean is 0.4 and the standard deviation is 0.08944.

5 7/8
6
5.5
5 3/4
Answer:
Greatest to Least order: 6, 5 7/8, 5 3/4, 5.5
Step-by-step explanation:
First it's 6, then it's 5 7/8 because 5 7/8 = 5.875, then 5 3/4 because 5 3/4 = 5.75, and then 5.5 which is the lowest number.
Y=2x + 4? What type of graph represent the solutions of the equation
Answer:
Ummm Linear? Up 2 Over 4
Step-by-step explanation:
Which equation below matches the relationship shown in the table?
Answer:
y = 3x + 0.5
Step-by-step explanation:
Use the line tool to graph the equation on the coordinate plane.
y = 3/4x
Step-by-step explanation:
in the equation y=mx+b, m corresponds to the slope, and b corresponds to the y-intercept. Since b is 0 at this case, we will start at (0,0). From here you can graph the line with the slope. Since it is 3/4, you would move up 3 units, and to the right 4 units to end up with the point (4,3). Now you have the two points (0,0) and (4,3), so all you need to do is connect them to form the line.
There are three customer service operators manning a helpline: Alex, Bobby, Charlie. Charlie is relatively new and takes one third as many calls as Bobby. Alex handles 6 times as many calls as Charlie.
What proportion of calls does Bobby handle?
Answer:
Bobby answers 30% of all phone calls.
Step-by-step explanation:
To determine the proportion of calls that Bobby answers in the call center, knowing that Charlie handles one third as many calls as him, and that Alex handles six times as many calls as Charlie, the following equivalence must be made:
A = 6 C (1/3B x 6 = 2B)
B = B
C = 1/3 B
2B + B + 1/3 B = 100
3 1/3 B = 100
3.33 B = 100
B = 100 / 3.33
B = 30
Therefore, Bobby answers 30% of calls, Alex answers 60% and Charlie 10%.

How many degrees of freedom will the error have in a randomized block design with five treatments and three blocks?
a. 2.
b. It will depend on the total sample size.
c.4.
d. 8.
Answer:
A. 2Step-by-step explanation:
Degree of freedom is expressed according to the formula as shown;
Degree of freedom = Sample size (Treatments) - number of parameters(Block)
Given
Number of treatments = 5
Number of blocks = 3
Degree of freedom = 5 - 3
Degree of freedom = 2
Hence the error will have 2 degrees of freedom in the randomized block design.
