Answer:
The null hypothesis is [tex]H_0: \mu = 4.1[/tex]
The alternate hypothesis is [tex]H_a: \mu \neq 4.1[/tex]
Step-by-step explanation:
The diameter of a spindle in a small motor is supposed to be 4.1 millimeters
This means that the null hypothesis is that the diameter has the supposed value, that is, [tex]H_0: \mu = 4.1[/tex]
If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 41 spindles to determine whether the mean diameter has moved away from the required measurement.
Tests if it has moved away, that is, if the mean is different from the specified value of 4.1. So the alternate hypothesis is [tex]H_a: \mu \neq 4.1[/tex]

There are 20 more dogs at the pet store than cats. If there are 7 cats, which equation can be used to find the number of dogs, d, at the pet store?
Answer:
if d=dogs and c=cats then c+20=d
Step-by-step explanation:
Answer:
20 + 7 = 27 dogs
Step-by-step explanation:
If there are 20 more dogs than there are cats, you add the number of cats with how many more dogs. 20 + 7 = 27 dogs.

What is Logarithm?The power to which a number must be increased in order to obtain another number is known as a logarithm.
How many times must one "base" number be multiplied by itself in order to generate another specific number? The answer is found using a logarithm (or log).
Given:
[tex]e^x[/tex] = 0.6
Now, taking log on both side
x log e= log 0.6
x= -0.22184874961
Hence, the value of x is -0.22.

Answer and Step-by-step explanation:
First step we can do is find the slope of the line.
To find the slope, use the following equation:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
(2, 0) will be the ([tex]x_{2}, y_{2}[/tex]) set, and (0, 4) will be the ([tex]x_2, x_1[/tex]) set.
[tex]\frac{0 - 4}{2 - 0} = \frac{-4}{2} = -2[/tex]
The slope of the line is -2.
Don't worry about the inequality part yet, make it look like an equation because you'll be more familiar with it.
y = -2x + b (b is the y-intercept)
The y-intercept is the point where the lines intersects with the y-axis. this y-value is 4.
y = -2x + 4 -- That is the equation of the line.
We see that all values make the inequality true is on the left side of this line. This means that the sign to replace the = sign with is >=, in which the values of y are less than what is plugged in and evaluated for x.
y <= -2x + 4
That is the inequality equation.

Which linear inequality is represented by the graph?
Oys 2x + 4
Oyszx+ 3
O yz {x + 3
O y 2x + 3
The linear inequality that represents the graph is: [tex]y \le \frac 23x + \frac 15[/tex]
The line of the inequality passes through the points:
(0,0.2) and (3,2.2)
So, the slope of the line is:
[tex]m = \frac{2.2 - 0.2}{3 - 0}[/tex]
[tex]m = \frac{2}{3 }[/tex]
The equation is then calculated as:
[tex]y =mx + c[/tex]
Where c represents the value of y, when x = 0.
So, we have:
[tex]y =\frac 23x + 0.2[/tex]
Rewrite as:
[tex]y =\frac 23x + \frac 15[/tex]
The down region is shaded, and the line is a closed line.
So, the inequality is:
[tex]y \le \frac 23x + \frac 15[/tex]

pack?
A 180
B 185
C 186
D 189
Answer:
B = 185
Step-by-step explanation:
You must divide 3,708 by 20.
3,708 divided by 20 = 185.4 = 185.
Answer:
B
Step-by-step explanation:
3,708/20=185.4
You obviously can't cut of the fries and wings- so u can't keep the .4 so the answer is 185

Represent the product of A and B geometrically given that point A is located at (2,45°) and B is located at (4, 45°). Give
the coordinate of AxB in polar form.
Answer:
(8,90°)
Step-by-step explanation:
To get this answer, you multiply the r values together to get 2*4 = 8. At the same time, you add the theta angles to get 45° + 45° = 90°
The general rule is that if A = (r,theta) and B = (s,phi) then
A*B = (r*s,theta+phi)
where the point (s,phi) is a polar form point.

According to a report in USA Today (February 1, 2012), more and more parents are helping their young adult children get homes. Suppose 8 persons in a random sample of 40 young adults who recently purchased a home in Kentucky got help from their parents. You have been asked to construct a 95% confidence interval for the population proportion of all young adults in Kentucky who got help from their parents. You have been asked to construct a 95% confidence interval for the population proportion of all young adults in Kentucky who got help from their parents. What is the margin of error for a 95% confidence interval for the population proportion?
a.1.645(0.0040)
b.1.645(0.0632)
c.1.96(0.0040)
d.1.96(0.0632)
Answer:
d.1.96(0.0632)
Step-by-step explanation:
The margin of error for a 95% confidence interval for the population proportion calculated as below:
Given that x = 8
n = Size of the sample = 40 (Large sample)
Sample population: P=x/n = 8/40 = 0.2; q = 1-p = 0.8
Standard error = [tex]\sqrt{pq/n}[/tex] = [tex]\sqrt{0.2(0.8)}/40[/tex] = 0.0682
95% of confidence Z∝ = 1.96
Margin of Error = Z∝ .[tex]\sqrt{pq/n}[/tex]
Margin of Error = 1.96(0.0682)
So, therefore, option d is correct.
