y=2x+7

Step-by-step explanation:

2x-y=-7

add y to each side

Identify the middle line for the function.
Ierofanga [76]
The solution to the problem is as follows:

<span>'(t) = 0 gives:
 
-24t + 60 = 0
 
t = 2.5
 
For this t, the second derivative s"(t) = -24 is negative.

And so, s(t) is maximum for t = 2.5.
 
Maximum height is:
 
S = -12(2.5)^2 + 60(2.5) +8 = 233ft

I hope my answer has come to your help. God bless and have a nice day ahead!

The weights, in pounds, for 15 horses in a stable were
sweet-ann [11.9K]

The median value remains unchanged if the four values are reported using the corrected weight.

The correct answer is an option (B)

We know that the mean is calculated by finding the sum of all the weights of the horses and then dividing by the number of horses.

Decreasing one of the weights would decrease the sum and therefore decrease the mean.

So, the choice A is incorrect.

We know that the range is the difference between the highest and lowest weights, so decreasing the lowest weight would increase the range.

So, the choice C is incorrect.

We know that the Standard deviation is calculated based on the mean weight of the horses.

And decreasing one of the weights decreases the mean and therefore would affect the standard deviation.

So, the choice D is incorrect.

Now, as we know the median the middle value in a sorted, ascending or descending list of values.

So, the median weight is found by ordering the horses’ weights from least to greatest and then determining the middle value from this list of weights.

Decreasing the value for the horse with the lowest weight doesn’t affect the median since it’s still the lowest value.

Therefore, the median value remains unchanged if the four values are reported using the corrected weight.

The correct answer is an option (B)

Dan buys 24 packets of nuts. Each packet of nuts weighs 225g. Work out the total weight of all the packets of nuts that dan buys
Vlada [557]

Answer:

 Total weight of the nuts bought by Dan =  5.4 kg

Explanation:

Number of packets of nuts bought by Dan = 24

Weight of each packet of nuts = 225g

 Total weight of the nuts bought by Dan = Number of packets of nuts bought by Dan * Weight of each packet of nuts

    Total weight of the nuts bought by Dan = 24 * 225 = 5400 g = 5400/1000 kg = 5.4 kg

    Total weight of the nuts bought by Dan =  5.4 kg
