It it fully correct
Hope you have a good day!
Can ai get brainliest?
X/5= 15
So we gotta get x alone sooo
Since it’s division we do reverse and do multiplication for the answer
So 15 times 5 is 75
X = 75
Answer:
a. Graph the relative frequency distribution for these results. What type of graph is ideal?
we must use bar graph
[Graph is attached with the name graph 1]
b.
Toward the Frequency Relative Frequency
volatiles 17 0.566666667
solvent 2 0.066666667
left side 7 0.233333333
right side 4 0.133333333
[Graphs is added in the attachment with the name graph 2]
c.
17/30 = 0.567
d.
se=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.567(1-0.567)}{30}}=0.091
standard error shows the variation in sampling distribution.
e.
The most plausible values for the fraction of dodder seedlings that grow toward the volatiles is:
\hat{p}\pm 2\sqrt{\frac{p(1-p)}{n}}=0.0567\pm 2(0.091)\: \: or\: \: (0.385,0.749)
This does not included the fraction expected (0.25).
Hi there!
Let's break this down. We know that there are 5 weight machines, and Leo spent an equal amount of time on all of them. Since we don't know how long he spent on each, we'll use x. Our equation so far is 5x. Then, we know that he spent 2/3 hour on the treadmill, which we will just add to the 5x. So, now our equation is 5x + 2/3. Lastly, we know that the total time Leo spent at the gym is 1 3/4 hours, which we set the last equation equal to. Our final equation is 5x + 2/3 = 1 3/4. Then, all we have to do is solve for x. What we can do to make this easier is to change all of the fractions into numbers. After changing everything, here is our equation: 5x + 40 = 105. Then, we will subtract 40 from each side and divide both sides by 5. Therefore, Leo spent 13 minutes on each weight machine.
ANSWER:
A) 5x + 2/3 = 1 3/4 ; Leo spent 13 minutes at each machine
Hope this helps!! :)

By <em>inverse</em> variation, the <em>electric</em> force between the two particles is 5 newtons when they are 20 centimeters apart.
<h3>How to use inverse variation to represent a situation</h3>
Herein we should present a statement that represents a <em>real life</em> situation and solve that statement. Here is an example:
<em>In accordance with the Coulomb's law, electric force is inversely proportional to the square of the distance between the two electrically charged particles. If you know that electric force is 20 N when the two particles are 10 cm apart, what is the electric force if the distance is doubled.</em>
Based on the statement, we have the following relationship:
F ∝ 1/r²
Where:
- F - Electric charge, in newtons
- r - Distance between the two electrically charged particles, in centimeters.
From such relation, we can determine the <em>resulting </em>force by the following equation:
F/20 = 10²/20²
F = 20 × 10²/20²
F = 5 N
By <em>inverse</em> variation, the <em>electric</em> force between the two particles is 5 newtons when they are 20 centimeters apart.
