Answer:
$68 to hire and 28.25 per hour to hire both
Step-by-step explanation:
The
amount of interest earned from a specific investment can be calculated by
multiplying the principal amount with the decimal equivalent of the given
percentage or interest rate. That is,
<span> I = P x i</span>
Substituting
the known values,
<span> I = ($580)(0.615)</span>
<span> I = $356.7</span>
<span>Answer:
$356.7</span>
Step-by-step explanation:
Given Input Value = 50%
Place the Percentage Value at the top over 100.
50/100
The given fraction is
50/100
On <u>reducing</u> the fraction, we get the exact form
50/100
which would equal 1/2.
The exact form of the fraction is
1/2
In the decimal form, the fraction can be written as 0.5.
Answer:
Part A
71°
Part B
The ladder is been used safely
Step-by-step explanation:
Part A
We solve the above question using Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = The distance between the house and the bottom of the ladder = 4 feet
Hypotenuse = Length of the ladder = 12 feet
x = Angle
Hence:
cos x = 4/12
cos x = 1/3
x = arc cos (1/3)
x = 70.528779366°
Approximately to the nearest degree
= 71°
Part B
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?
Angle x = 71°
Therefore, the ladder is been used safely
Answer:
a. 0.4
b. Not independent.
Step-by-step explanation:
a. We use the probability table attached below for our calculations.
-the probability that an agreement is reached on both sides is obtained from the table:
b. To determine whether the two events are independent, we compare the probabilities 
and 
where i denotes insurance and s denotes salaries:
Two events are considered to be independent, if and only if:
Hence, the events are not independent.
