Answer: The answer is b=–108
Step-by-step explanation: You’ll need to solve for b by simplifying the both sides of the equation, and then isolating the variable.
The answer is <span>25; it represents the hourly wage for the worker
</span>
<span> y = 8x + 25
x is hours
y depends on x hours so y-intercept represent the hourly wage.
The y-intercept is y when x = 0:
y = 8x + 25
x = 0
____
y = 8 * 0 + 25
y = 0 + 25
y = 25</span>
7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>

Answer:
X= O.8 or 10 over 12.5
Step-by-step explanation: Hope this helps darling
Assuming scores are normally distributed, a score of 82% on Ms. Smith's test corresponds to the
-th percentile, i.e.

where
is a random variable denoting scores on Ms. Smith's test.
Transform
to
, which follows the standard normal distribution:

which means Amy scored at the 99.98th percentile.
This makes it so that Karina needs to score
on Mr. Adams' test so that

Their test scores have the same
score computed above, so

so Karina needs to get a test score of at least 83.5%.
