Answer:
27.8% I think
Step-by-step explanation:
2(2t + 4) = 34(24 − 8t)
4t + 8 = 816 - 272t
4t + 272t = 816 - 8
276t = 808
t = 808/276
= 2.93 (to three significant figures)
The value of t is 2.93.
Answer:
2
Step-by-step explanation:
We have to get the value of the expression of - ∛(- 8).
Now, we can write the expression as
- ∛(- 8)
=![-\sqrt[3]{-8}](https://tex.z-dn.net/?f=-%5Csqrt%5B3%5D%7B-8%7D)
= 
{Converting into exponent form}
= ![-[(-2)^{3} ]^{\frac{1 }{3} }](https://tex.z-dn.net/?f=-%5B%28-2%29%5E%7B3%7D%20%5D%5E%7B%5Cfrac%7B1%20%7D%7B3%7D%20%7D)
{Since (- 2) × (- 2) × (- 2) = - 8}
= ![- [(-2)^{3\times \frac{1}{3} } ]](https://tex.z-dn.net/?f=-%20%5B%28-2%29%5E%7B3%5Ctimes%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%5D)
{Since we know that ![[x^{a}] ^{b} = x^{ab}](https://tex.z-dn.net/?f=%5Bx%5E%7Ba%7D%5D%20%5E%7Bb%7D%20%3D%20x%5E%7Bab%7D)
}
= - [- 2]
= 2 (Answer)
- a) An observation.
- b) A variable.
- c) A population parameter.
- d) A sample statistic.
Given that a survey asked the question, "Do you think a vaccination should be mandatory to enter shopping areas?" to a random sample of 1068 Jordanians, and the results showed that 71.2% responded that vaccination should mandatory, to determine which of the following is an observation, a variable, a sample statistic (value calculated based on the observed sample), or a population parameter, the following statistical reasoning must be performed:
(a) A Jordanian that was asked the question.
-An observation, as the person questioned is part of the study and therefore, it is an individual observation that makes up the trend.
(b) The response of the Jordanian.
-A variable, since it is one of the two possible answers that the survey has.
(c) 71.2%.
-A population parameter, because it represents a specific percentage with respect to the total population.
(d) The percentage of all Jordanians who agreed with the statement that vaccination should be mandatory to enter shopping areas.
-A sample statistic, since it is a statistical element that arises from the survey.

A can of paint will be 10 dollars. the rollers will also be 10 dollars. makes sense with 2 can being 20 and then a roller being 10 equaling 30 dollars. same with 3 cans being 30 and 2 rollers being 20 adding up to 50
