And orange falls of a display at a store and rolls 5 meters in 2.5 seconds.What is the average speed of the orange

Answers

Answer:

The orange moves at 2M/s

5/2.5=2

2meters/secon

The average speed of the orange is 2 m/sec.

Given that, orange falls off a display at a store and rolls 5 meters in 2.5 seconds.

We need to find the average speed of the orange.

What is the average speed formula?

Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speeds, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.

The formula for average speed is given as:

Average Speed = Total distance covered ÷ Total time taken

Now, average speed=5/2.5=2 m/sec.

Therefore, the average speed of the orange is 2 m/sec.

Answer: The median is 28208 the mean is 28234.6

Step-by-step explanation:

The mode is the number that is repeated the most there can be more than one mode.

Answer:

All in ft

Mean: 28,235

Median: 28,208

Range: 1,245

Step-by-step explanation:

Mean is the sum of the elements divided by the number of elements.

(29035+28250+28208+27890+27790)/5 = 28235

Median is the element in the exact middle of the set (if there is an even number of elements, take the average of the two elements in the middle).

After rearranging the numbers, we can see 28208 is in the exact middle.

27790 27890 28208 28250 29035

Range is the difference between the smallest and largest number in the set.

29035-27790=1245

Brenda bought three time more black fabric than red fabric. She bought 72 inches of red fabric. If fabric costs 7.25 per yard, how much did Brenda spend on fabric

Answers

Answer:

$58 dollars

Step-by-step explanation:

Step 1: Find price of Red Fabric. So Brenda bougt 72 inches. So we convert that to amount of yards.(36 inches=1 yard). So the equation is 72/36=2 yards. Then do 7.25x2= $14.50 for red fabric.

Step 2: Find price of Black Fabric. So Brenda bought 3 times more the red favric. So she 216(72x3 is how I got the number). Now divide 216 by 36. That equals 6. So now do 7.25x6= $43.50

Step 3: Add the prices. So now add the price of the red and black fabric to find the answer. So $43.50 + $14.50= $58

Hence, the answer is $58 dollars.

The triangle is a right-angled triangle.

The length of the perpendicular = 17 unit.

Two angles of the triangle are 45° and 45°.

That means, base = 17 unit.

B) 60 adult tickets and 180 student tickets
C) 180 adult tickets and 60 student tickets
D) 200 adult tickets and 40 student tickets

Answers

[tex]\huge{ \mathfrak{  \underline{ Answer} \:  \:  ✓ }}[/tex]

let the number of

adults be x

children be y

Total number of people : adults + children

x + y = 240

x = 240 - y - [1]

Total money earned from adults :

6 × x = 6x

Total money earned from children :

2 × y = 2y

Therefore, total money = money earned from each Adult and children.

6x + 2y = 1200 -[2]

Now, let's plug the value of x from equation [1] into equation [2]

6 (240 - y) + 2y = 1200

1440 - 6y + 2y = 1200

-4y = 1200 - 1440

-4y = - 240

y = 60

let's plug the value of y in equation [1]

x = 240 - y

x = 240 - 60

x = 180

Hence, we get :

total adults = x = 180

total children = y = 60

Correct option is C

For a 95% confidence interval what would the sample size need to be as it's most conservative to have a 2% margin of error

Answers

Answer:

The size of the sample 'n' = 2401

Step-by-step explanation:

Step:1

Given that the margin of error = 2 % = 0.02

The margin of error is determined by

              [tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]

we know that the proportion

               [tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]

Step:2

The margin of error is determined by

              [tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]

              [tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]

              √n  = 49

Squaring on both sides, we get

                n = 49 × 49

                n = 2401

Final answer:-

The size of the sample 'n' = 2401

For what value of x is line / parallel to line m in this figure?

Answers

Answer:

132

Step-by-step explanation:

The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180

This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180

So x = 180 - 48

180 - 48 = 132

Hence, x = 132
