Answer: Chet is 6 years old now
Step-by-step explanation:
Chet is 6 years old now and his father is 5 x 6 years = 30 years old now.
In 6 years, Chet will be 12 years old, so his father will be 3 x 12 years old = 36 years old.
The answer is 28 %, this is the percent of the class with blue eyes.
So lets do it like this:
z = (X-Mean)/SD
<span>z1 = (8-12)/2 = - 2 </span>
<span>z2 = (16-12)/2 = + 2 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean more or less 2SD covers 95% of the values </span>
So t<span>he percentage of data points falling between 8 and 16 = 95%
</span>I hope this can help
Answer 1.)is 196 simplify 7^2 to 49 6*(49-15)-2^3. Do 49-15=34 6*34-2^3. Do 2^3 to 8 6*34-8 =204-8 which is 196 hope this helps you
