Answer:
1
Step-by-step explanation:
In order to figure out the degree of functions find the highest exponent and that is the degree. Since there is no exponent here it is 1.
Using the Empirical Rule, it is found that 229 batteries have lifetimes between 3.0 hours and 3.4 hours.
--------------------------
By the Empirical Rule, in a normal variable: 68% of the measures are within 1 standard deviation of the mean, 95% are within 2 and 99.7% are within 3.
--------------------------
- Mean of 3.2 hours with a standard deviation of 0.2 hours.
3 = 3.2 - 2(0.1)
3.4 = 3.2 + 2(0.1)
- Thus, between 3 and 3.4 hours is <u>within 2 standard deviations of the mean</u>, which is 95%.
- Out of 241 batteries:
229 batteries have lifetimes between 3.0 hours and 3.4 hours.
A similar problem is given at brainly.com/question/24552083
20 < 12 ⋅ <em>x</em> = 64
This is somewhat of a false equation though, due to the left side "20" is not less than the right side "12
", which means that the given statement is false.
So I switched it up and made the variable "12"
<u>12 < 20 ⋅ </u><u><em>x</em></u><u> = 64
</u>
12x - 20 = 64
12x = 64 + 20
12x = 84
12x⁄12 = 84⁄12
x = 7

Answer:
5.33lb of candy
Step-by-step explanation:
First, you'd need to set up a proportion.
4 pounds x poinds
----------- = -------------
9 dollars 12 dollars
Then, cross multiply.
9x = 4(12)
9x = 48
x = 48/9
And your answer is x = 5.33!
Hope I helped! ☺
