Answer:
D
Step-by-step explanation:
The domain of a graph is its horizontal extent. It is all the values of x for which a function value is defined.
__
This graph shows a relationship that is defined from x=0 to x=7. It is not restricted to integer values of x. The domain is ...
real numbers from 0 to 7.
The right statement is Sarah must sell in between 40 and 50 springtime bouquets true if Sarah needs to make a profit of at least $9,000.
Knowing that,
Sarah owns a flower shop and can model the profits from selling springtime bouquets using this equation,
Where b is the number of springtime bouquets, .
We have to determine,
Which statement is true if Sarah needs to make a profit of at least $9,000.
According to the question,
Sarah owns a flower shop and can model the profits from selling springtime bouquets using this equation,
Divide the equation by -5,
Factorize the equation for the value of profit,
Hence, Sarah must sell between 40 and 50 springtime bouquets.
Have a nice day
Answer:
She ran
Step-by-step explanation:
To find the answer you multiply the amount of races (9) by the length of each race (7/10 km).
Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15
the three angles make a sum of 180: x+4x +5x+15=180
10x=165
x=16.5
the second angle is 4x=4*16.5=66
To solve this problem, we make use of the z statistic.
What we have to do here is to find for the z score using the given data and
from the standard probability tables for z, we locate the proportion of the
fish longer than 12 inches.
The formula for calculating the z score is:
z = (x – μ) / σ
where,
x = the sample value = 12 inches
μ = the sample mean = 11 inches
σ = 2 inches
so,
z = (12 – 11) / 2
z = 1 / 2
z = 0.5
Since we are looking for the values greater than 12, so
this is a right tailed test. Using the tables, the value of p at this value of
z is:
p (z = 0.5) = 0.3085
Therefore there is a 30.85% probability that the fish is
longer than 12 inches.
