Answer:
X = 3 x − 14
y = − x + 5
Step-by-step explanation:
Solve for the first variable, then substitute the result into the other equation.
Answer:
I think its the third one sorry if I got it wrong I tried my best
93% of x = 198 tons
93% = 93/100
= 0.93
0.93 * x = 198 tons
Divide both sides by 0.93:
x = 198/0.93
x = 212.90 -> Final Answer.
100+25*12=
100+300=
400
400-320=80
I=PRT
I=80
P=principal=320
T=1 year
R=?
80=320*1*?
80=320?
divide both sides by 320
0.25=?
that is 25%
answer is 25%
Using the Empirical Rule, it is found that 68% of the data should be between 25.5 and 30.5.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Within one standard deviation of the mean, hence, 68% of the data should be between 25.5 and 30.5.
