Answer:

Noah did not make any error

Step-by-step explanation:

The median of a list of strictly increasing numbers is simply the middle number. If there's an even number of numbers in the list, then the median is the average of the middle two terms.

Here, the numbers are 115, 109, 117, 136, 127, 131. When ordered from least to greatest, we get: 109, 115, 117, 127, 131, and 136, which is what Noah got.

Since there are 6 numbers (6 is even), the median will be the average of the middle two numbers, which are 117 and 127: (117 + 127)/2 = 244/2 = 122

So, Noah was correct.

oe’s Pizza Palace needs a program to calculate the number of slices a pizza of any size can be divided into. The program should

Shkiper50 [21]

Answer:

# the user is prompted to enter diameter in inch

diameter = int(input("Enter the diameter of the pizza you want (in inch): "))

# the value of PI is saved as a constant

PI = 3.14159

# the area of the pizza is calculated using pi r squared

# the value of r is diameter divide by 2

area = PI * ((diameter / 2) ** 2)

# the value of area is displayed

print(area)

# the number of slice is calculated as area divide by 14.125

# integer division is use to get number of slice

number_of_slice = area // 14.125

# the number of slice is displayed to the user

print("Your number of pizza slice is: ", number_of_slice)

Step-by-step explanation:

The code is written in python and well commented. A sample image of output when code is executed is attached

0.5x+7/3 = 21/4 cross multiply

TiliK225 [7]

Solving the expression $\frac{0.5x+7}{3}=\frac{21}{4}$ we get: $x=\frac{35}{2}\,\,or\,\,x=17.5$

Step-by-step explanation:

Solving the expression: $\frac{0.5x+7}{3}=\frac{21}{4}$

Solving by cross multiplying:

$\frac{0.5x+7}{3}=\frac{21}{4}\\(0.5x+7)*4=21*3\\Simplifying:\\2x+28=63\\Adding\,\,-28\,\,on\,\,both\,\,sides:\\2x+28-28=63-28\\2x=35\\Divide\,\,both\,\,sides\,\,by\,\,2\\\frac{2x}{2}=\frac{35}{2}\\x=\frac{35}{2}\,\,or\,\,x=17.5$

So, solving the expression $\frac{0.5x+7}{3}=\frac{21}{4}$ we get: $x=\frac{35}{2}\,\,or\,\,x=17.5$

Need help what would the depth be after 30 minutes

avanturin [10]

Answer:

108.7 ft

Step-by-step explanation:

Put 30 where x is and do the arithmetic.

y = -3.29·30 -10 = -98.7 -10 = -108.7

The trend line predicts the depth to be 108.7 ft after 30 minutes.

_____

<em>Comment on this problem</em>

Real-world considerations in scuba diving may cause the diver to level off or head toward the surface before 30 minutes elapse. The trend line does not model these effects.
