1 answer:
Grace [21]3 years ago
3 0

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the box plot is not attached.

However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores

To answer this question, I will make use of the attached box plot.

IQR is calculated as:

IQR = Q_3 - Q_1

Q_1 and Q_3 are represented by the vertical edges of the rectangle in the box plot. [See attachment]

Reading Q_1 and Q_3, we have:

Q_1 = 37

Q_3 = 50

The IQR is:

IQR = 50 - 37

IQR = 13

<em>Hence, the range that describes the middle 50% of the attached plot is 13</em>

HELP !! a sandwich shop purchases a used pizza oven for $875. after 5 years, the oven will have to be discarded and replaced. wr
Sladkaya [172]
<h3>Answer: V = -175t + 875</h3>

==================================================

Explanation:

I'll use y in place of V for now. Also, I'll use x in place of t.

x = number of years

y = value of the oven

Initially, the oven's value is $875, so x = 0 and y = 875 pair up together. The point (0,875) is on the line.

The point (5, 0) is also on the line to indicate that x = 5 years later is when the value of the oven is y = 0 dollars.

We need to find the equation of the line through (0,875) and (5,0)

First we'll need the slope

m = (y2-y1)/(x2-x1)

m = (0-875)/(5-0)

m = -175

The negative slope means the oven is losing 175 dollars in value each year.

The y intercept is b = 875 as this is the initial value of the oven

Put together, y = mx+b turns into y = -175x+875

If we plugged x = 0 into this equation, we'd get y = 875

Similarly, plugging x = 5 into y = -175x+875 leads to y = 0. This helps check we have the right equation

Lastly, replace x with t and replace y with V to end up with V = -175t + 875 which is our final answer.

In a GP the second and fourth terms are 0.04 and I respectively find the common ratio and the first term​
Reptile [31]

Answer:

common ratio=0.5, a1= 0.08

Step-by-step explanation:

r=a3/a2

r=a4/a3

compare both we get:

a3/a2=a4/a3

subtitute a2=0.04 and a4=1

a3/0.04=1/a3

(a3)^2=0.04*1

(a3)^2=0.04

taking square root in both sides

a3=0.02

For r, r=a3/a2

subtitute a3 and a2 above

r=0.02/0.04

r=0.5 common ratio

For a1

r=a2/a1

0.5=0.04/a1

a1=0.04/0.5

a1=0.08

The new cylinder can has radius of 5cm and a height of 9cm how many square centimeters of aluminum will it take to make this new
m_a_m_a [10]

Answer: 282.85\ cm^2

Step-by-step explanation:

Given

Radius of cylinder r=5\ cm

The height of the cylinder is h=9\ cm

The surface area of a cylinder is 2\pi rh

If only the outer is considered then, the area required is

\Rightarrow A=2\times \dfrac{22}{7}\times 5\times 9\\\\\Rightarrow A=282.85\ cm^2
