The graph is misleading because the vertical range is too small creating the impression that differences are greater than they actually are.

The most accurate would be the second statement: <span>The graph is misleading because it uses 3-dimensional bars.

The vertical range is just enough. It only appears small because the bars are in 3D. It should have been in 2D so that we could directly trace it to how much frequency each category is. Even the axes are in 3D also.</span>

The Johnson twins were born nine years after their older sister. This year, the product of the three siblings ages is exactly 18

KATRIN_1 [288]

Answer: The age of the twins is 10 years.

Step-by-step explanation:

Suppose the age of older sister be x

Let the age of twins sister be x-9, as they are born after 9 years.

Product of their ages be

$x(x-9)(x-9)\\\\=x(x^2-18x+81)\\\\=x^3-18x^2+81x$

Sum of their ages will be

$x+x-9+x-9\\\\=3x-18$

According to question,

$1861+3x-18=x^3-18x^2+81x\\\\x^3-18x^2+81x-3x+18-1861=0\\\\x^3-18x^2+78x-1843=0\\\\x=19$

So, Age of older sister will be 19 years.

Age of the twins will be

$19-9=10\ years$

Hence, the age of the twins is 10 years.

Quadrilateral ABCD is inscribed in the circle. Which sentence is true?

astra-53 [7]

Answer:

A) A and B are supplementary

Step-by-step explanation:

we know that

For any inscribed quadrilateral in the circle , opposite angles will be supplementary

so

In this problem

Angle A and Angle B are supplementary angles

$m\angle A+m\angle C=180^o$

Angle B and Angle D are supplementary angles

$m\angle B+m\angle D=180^o$

therefore

<u><em>The sentences that are true </em></u>

A) A and B are supplementary
