Answer:
(3,2) just use a slope triangle (over 2 up 3) and do it in reverse
Answer:
x = - 4
Step-by-step explanation:
First do distributive property
5x-15=10x+5
then add 15
5x=10x+20
-10x
-5x=20
divide 5
x=-4
To solve this problem, we make use of the z statistic. The
formula for z score is:
z = (x – μ) / s
where,
x = is the sample score = 21 or higher
μ = the population mean = 20.8
s = the standard deviation = 4.8
Solving for the z score:
z = (21 – 20.8) / 4.8
z = 0.0417
Next step to do is to find for the p value using the
standard distribution tables at z = 0.04. Since we are looking for the
probability of getting 21 or higher, therefore this is a right tailed test,
hence
p = 0.516
<span>So there is about 51.6% that a student will get a score of
21 or greater.</span>
Answer:
Step-by-step explanation:
Dividing both sides by -7.
There is only one solution that satisfies the equation.
F(n) = 5n
You are being told n is the number of tables, and there are 15 tables:
f(15) = 5(15)
F(n) = 75
You need 75 candles.
