Answer:
He worked a total of 5 hours.
Step-by-step explanation:
The first hour the man makes $35 dollars for the first hour then for the other hours he earns $23 dollars, right? So we start off with 35.
35 = one hour.
35 + 23 = 2 hours . = 58.
35 + 23 + 23 = 3 hours. = 81.
35 + 23 + 23 + 23 = 4 hours. = 104.
35 + 23 + 23 + 23 + 23 = 5 hours. = 127.
We were looking for if the man earned $127 dollars how many hours would be be working.
He'd be working 5 hours.
Hope this helps (:
Answer:
The test statistic value is 1.474.
Step-by-step explanation:
In this case we need to determine whether the plant is making a higher than expected number of irregular t-shirts.
If more than 8% of the t-shirts manufactured at a plant are classified as irregular, the manager has to do an investigation to try to find the source of the increased mistakes in the manufacturing process..
The hypothesis for this test can be defined as follows:
<em>H₀</em>: The proportion of irregular t-shirts is 8%, i.e. <em>p</em> = 0.08.
<em>Hₐ</em>: The proportion of irregular t-shirts is more than 8%, i.e. <em>p</em> > 0.08.
The information provided is:
<em>n</em> = 100
<em>X</em> = number of irregular t-shirts = 12
Compute the sample proportion as follows:

Compute the test statistic as follows:


Thus, the test statistic value is 1.474.
Answer:
158.4 degrees.
Step-by-step explanation:
A line is 180 degress in total so subtract 21.6 from 180. Then you get 158.4
Answer:
The function has a domain of all real numbers.
The function has a range of {y|–∞ < y <∞ }.
The function is a reflection of y=∛x
Step-by-step explanation:
Given:
f(x)=-∛x
domain is set of all values that x can take for which the function is defined, so
for above function domain= set of all real numbers
range is set of values that corresponds to the set of values of domain, so for given f(x) range={y|–∞ < y <∞ } set of real numbers
Now f(x)=-∛x hence its reflection will be
-f(x)=-(-∛x)
y=∛x !
