(a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their watermelon crop (in dollars). What is the margin of error (in dollars)
Answer:
The margin of error (E) [tex]=0.49[/tex]
Step-by-step explanation:
Given,
mean [tex]\bar{x}=6.88[/tex]
standard deviation [tex]\sigma=1.90[/tex]
sample size [tex]n=41[/tex]
[tex]90\% \quad \text{confidence interval}[/tex]
Critical value [tex]=\frac{z_\alpha}{2}\quad \quad\quad[\because\;\alpha=1-\text{confidence interval}][/tex]
[tex]=1-0.90[/tex]
[tex]\Rightarrow \alpha=0.1[/tex]
Critical value [tex]=\frac{z_{0.1}}{2}[/tex]
[tex]=z_{0.05}[/tex]
[tex]=1.645[/tex]
The margin of error (E) [tex]=\frac{z_\alpha}{2} \times\frac{\sigma}{\sqrt{n} }[/tex]
[tex]=1.645\times\frac{1.90}{\sqrt{41} }[/tex]
[tex]=0.49[/tex]
Hence, The margin of error (E) [tex]=0.49[/tex]

the base is ?
the value of the expression is ?
Answer:
The base is 5
The exponent is 4
[tex]5\cdot 5\cdot 5\cdot 5=5^4[/tex]
And the value is 625
Step-by-step explanation:
Exponentials
If a number is multiplied by itself n times like shown below:
[tex]x\cdot x\cdot x\cdot ...x[/tex]
It can be written in exponential form:
[tex]x\cdot x\cdot x\cdot ...x=x^n[/tex]
Where x is the base and n is the exponent.
In the expression:
[tex]5\cdot 5\cdot 5\cdot 5[/tex]
The base is 5
The exponent is 4
Writing the expression using an exponent:
[tex]\mathbf{5\cdot 5\cdot 5\cdot 5=5^4}[/tex]
And the value is 625
What is the equation of the line in slope-intercept form?
Answer:
The equation of the line in slope-intercept form is:
[tex]y = x + 4[/tex]
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept
Given the equation
(1, 5) (2, 6)Determining the slope between (1, 5) and (2, 6)
(x₁, y₁) = (1, 5)
(x₂, y₂) = (2, 6)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [5 - 4] / [1 - 0]
= 1 / 1
= 1
Thus, the slope of the line = m = 1
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 4
Thus, the y-intercept b = 4
now substituting b = 4 and m = 1 in the slope-intercept form
[tex]y = mx + b[/tex]
[tex]y = (1)x + 4[/tex]
[tex]y = x + 4[/tex]
Therefore, the equation of the line in slope-intercept form is:
[tex]y = x + 4[/tex]
you have been given an engine repair job that has a job time of 7 hours how many minutes should you allow for your job?
Answer:
[tex]Job\ Time = 420\ minutes[/tex]
Step-by-step explanation:
Given
[tex]Job\ Time = 7\ hours[/tex]
Required
Determine the job time in minutes
To do this, we simply convert the time to minutes.
[tex]1\ hour = 60\ minutes[/tex]
[tex]7\ hours = 7 * 60\ minutes[/tex]
So, we have:
[tex]Job\ Time = 7 * 60\ minutes[/tex]
[tex]Job\ Time = 420\ minutes[/tex]
Hence, the job time in minutes is 420 minutes

Nikhil, Davina and Sid share a tin of celebrations amongst themselves in the ratio of 8:12:20 respectively.
Given that Davina gets 48 sweets, calculate the total number of sweets that were in the tin.
Answer:
160
Step-by-step explanation:
n : d : s
8 : 12 : 20
davina = 48 sweets
48/12 = 4
8 + 12 + 20 = 40
40 x 4 = 160 sweets total
What is 254212610 rounded to nearest million
Answer:
Step-by-step explanation:
Starting from the right, put this into groups of three so you can see for sure where a million is.
254 212 610
A million is right where the 4 is. So use the hundred thousands (the second 2) to round to the nearest million. Since 2 is less than 5, it rounds like this.

Answer:
Step-by-step explanation:
Because these two triangles are isoceles triangles, two angles are the same, which in this case would be 78. 78 times 2 would give us 156 for the right triangle, but since 180 - 156 does not equal 16, they are not similar nor congruent.
What is the solution of the following systems of equations? y = 1/2x
y = -x -3
Answer:
x = -2, y = -1
Step-by-step explanation:
System of Equations
Solve the system:
y = 1/2x
y = -x - 3
Multiplying the first equation by 2:
2y = x
Substituting x in the second equation:
y = -2y - 3
Adding 2y:
3y = -3
y = -3/3
y = -1
And x = 2*(-1) = -2
Solution: x = -2, y = -1
pls help, basic algebra problem with guidance
Answer:
x = 43000/9 or 4777.7 (i'm not 100% sure on this, so i apologize if i'm incorrect)
Step-by-step explanation:
The equation you were given was:
amount of solution • rate of concentration = amount of pure acid
By looking at the question, you can conclude that the amount of solution being used is 18%. You need to turn that into a decimal, therefore it'd be 0.18.
You can also conclude that the amount of pure acid being used is 860 milliliters. So, from this, you're able to fill in 2 parts of the equation:
0.18 • x = 860 mL
Now, all there's left to do is solve for x! To do this ,you'll need to rearrange the multiplication problem into a division problem.
860 / 0.18 = x
x = 43000/9 or 4777.7
