Answer:
16 robots
Step-by-step explanation:
Each worker can move 12 boxes/minute and there are 24 workers.
24 x 12 = 288
Divide the total work by 18 (since a robot can move 18 boxes/minute)
288 ÷ 18 = 16

The chart shows data for an object moving at a constant acceleration. A 2 column table with 4 rows. The first column is labeled time in seconds with entries 0, 1, 2, 3. The second column is labeled velocity in meters per second with entries 0, X, Y, Z. Which values best complete the chart? X: 0 Y: 0 Z: 0 X: 2 Y: 4 Z: 6 X: 3 Y: 3 Z: 3 X: 1 Y: 5 Z: 8
Answer:
its B
Step-by-step explanation:
X:2
Y:4
Z:6
The values that best complete the chart as per the concept of ratio are X:2, Y:4, and Z:6.
To determine the correct values for the chart, let's analyze the given information about an object moving at a constant acceleration:
The first column represents time in seconds (0, 1, 2, 3).
The second column represents velocity in meters per second (0, X, Y, Z).
Since the object is moving at a constant acceleration, its velocity is changing by the same amount in equal time intervals.
We can use the formula for constant acceleration:
Velocity (V) = Initial Velocity (U) + (Acceleration × Time)
Given that the object starts from rest (initial velocity, U = 0), we can deduce the following:
At time 1 second (T = 1), the object's velocity is X m/s.
At time 2 seconds (T = 2), the object's velocity is Y m/s.
At time 3 seconds (T = 3), the object's velocity is Z m/s.
Based on this information, the correct values for the chart are:
X: 2 (Velocity at 1 second is 2 m/s)
Y: 4 (Velocity at 2 seconds is 4 m/s)
Z: 6 (Velocity at 3 seconds is 6 m/s)

Answer:
Let the number be x. Then, 4/5x - 3/4x = 4. Hence, The required number is 80.
Step-by-step explanation:
Let the number be x.
According to the question, lets form an equation

As part of an environmental impact study, a power company wants to estimate the difference in mean water temperature between the discharge of its plant and the offshore waters. How many sample measurements must be taken at each site to estimate the true difference between means to within .2°C with 95% confidence? Assume that the standard deviation in readings is about 1.5°C at each site and the same number of readings will be taken at each site.
Using the z-distribution, it is found that 217 sample measurements should be taken at each site.
The margin of error of a z-confidence interval is given by:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which:
z is the critical value. [tex]\sigma[/tex] is the population standard deviation. n is the sample size.The first step is finding the critical value, which is z with a p-value of [tex]\frac{1 + \alpha}{2}[/tex], in which [tex]\alpha[/tex] is the confidence level.
In this problem, [tex]\alpha = 0.95[/tex], thus, z with a p-value of [tex]\frac{1 + 0.95}{2} = 0.975[/tex], which means that it is z = 1.96.
Estimate of the standard deviation of 1.5, thus, [tex]\sigma = 1.5[/tex].
We want the sample for a margin of error of 0.2ºC, thus, we have to solve for n when [tex]M = 0.2[/tex].
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]0.2 = 1.96\frac{1.5}{\sqrt{n}}[/tex]
[tex]0.2\sqrt{n} = 1.96(1.5)[/tex]
[tex]\sqrt{n} = \frac{1.96(1.5)}{0.2}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96(1.5)}{0.2})^2[/tex]
[tex]n = 216.1[/tex]
Rounding up:
217 sample measurements should be taken at each site.

Answer:
[tex]a_{16} = 121[/tex].
Step-by-step explanation:
To go from the first term [tex]a_{1}[/tex] of this sequence to the second term [tex]a_{2}[/tex], add [tex]d[/tex] to [tex]a_{1}\![/tex].
To go from the first term [tex]a_{1}[/tex] of this sequence to the third term [tex]a_{3}[/tex], add [tex]2\, d[/tex] to [tex]a_{1}\![/tex].
In general, going from the first term [tex]a_{1}[/tex] of an arithmetic sequence to the [tex]k[/tex]th term, add [tex](k - 1)\, d[/tex] to [tex]a_{1}\![/tex].
Thus, given an arithmetic sequence with [tex]a_{1}[/tex] as the first term and [tex]d[/tex] as the common difference, the [tex]k[/tex]th term of this sequence would be [tex]a_{k} = a_{1} + (k - 1)\, d[/tex].
In this question, [tex]a_{1} = 1[/tex] and [tex]d = 8[/tex] for this arithmetic sequence. The [tex]16[/tex]th term of this sequence would be:
[tex]\begin{aligned}a_{16} &= 1 + (16 - 1) \times 8 \\ &= 1 + 15 \times 8 \\ &= 121\end{aligned}[/tex].

A large pool has a faucet to allow water to enter the pool and a drain to allow water to leave the pool.
Each minute, the faucet allows 14 2/3 gallons of water to enter the pool, and the drain allows 16 3/4 gallons to leave the pool.
What is the change in the amount of water in the pool after 1 1/2 minutes?
Enter your answer as a simplified mixed number by filling in the boxes.
Answer:
-3 1/8 Gallons
Step-by-step explanation:
First, you need to understand how many gallons are being lost per minute.
14 2/3 - 16 3/4 =1 1/12
After this, you just need to multiply 1 1/12 by 1 1/2. This amounts to 3 1/8.

When Jerome travels on the highway, he sets his cruise control at 65 mi/h. The function f(x)=65x represents his total distance f(x) when he has traveled x hours. How many miles will he have travelled after 3.5 hours of driving on the highway
The number of miles that he will have traveled after 3.5 hours of driving on the highway is 227.5 miles.
The function given to solve the question is: f(x) = 65x
where, x = number of hours
Therefore, when he travelled for 3.5 hours, the number of miles will be gotten by multiplying 65 by 3.5.
f(x) = 65x
= 65 × 3.5
= 227.5 miles.
Therefore, the number of miles that he will have travelled after 3.5 hours of driving on the highway is 227.5 miles.
