A watermelon was ejected from a catapult reaching a maximum height of 20 ft. The watermelon left the catapult when it was 4 ft o
Paraphin [41]

Answer:

Step-by-step explanation:

No, the equation cannot be written with the given information. The distance from the catapult when the watermelon reached the maximum height is needed. Since the watermelon did not start on the ground, it cannot be assumed that the maximum was reached half the distance to the landing point.

A 25-year old woman burns 200−20t cal/hr while walking on her treadmill. Her caloric intake from drinking Gatorade is 110t calor
marin [14]

The net decrease in calories after walking for 5 hours is 50 calorie.

According to the statement

we have given that the

A 25-year old woman burns 200−20t cal/hr and Her caloric intake from drinking Gatorade is 110t calories during the t hour.

And we have to find the net decrease in calories after walking for 5 hours.

So, For this purpose,

We know that the

calories burns in one hour = 200−20t

calories burns in 5 hours = 5(200−20t)

calories burns in 5 hours = 1000 - 100t

Now,

Calorie intake in t hours = 110t

And

net decrease in calories after walking for 5 hours =  100t - 1000 + 110t

put t is 5 then

net decrease in calories after walking for 5 hours = 210(5) - 1000

net decrease is 50 cal.

So, The net decrease in calories after walking for 5 hours is 50 calorie.

Graph the line for y+1=−3/5(x−4) on the coordinate plane
Andrej [43]
Solve for y:
y + 1 = -3/5x + 2.4  (multiply 4 by 3/5 no negatives because negative times a negative is a positive)
y = -3/5x + 1.4
Now graph the y-intercept of 1.4. 
Then plot points using slope. 
Hope this helps and let me know if you have more questions!

Exercises 1–5
Degger [83]

Answer:  The estimated value for population mean rating based on these ten sampled ratings is 7.3 .

Step-by-step explanation:

Given : A random sample of size ten produced the following ratings in the computer games rating example in the  last lesson:

12, 5, 2, 4, 1, 4, 18, 10, 1, 16.

Let x denotes any value in the above data.

{\sum_{i=1}^{10}x_i}{10}=73

We know that the sample mean(\overline{x}) is the best estimate to the population mean(\mu).

Sample mean=\overline{x}=\dfrac{\sum_{i=1}^{n}x_i}{n}

Here , n= 10

\overline{x}=\dfrac{\sum_{i=1}^{10}x_i}{10}

\overline{x}=\dfrac{73}{10}=7.3

Therefore , the estimated value for population mean rating based on these ten sampled ratings= 7.3
