allochka39001 [22]

Answer:

B. (-5.65 < -5.6)

Step-by-step explanation:

-5.6 is considered -5.60 if you fill in the missing decimal point to create two spaces after the decimal to compare. Since both decimals are negatives, -5.6 is closer to 0 on the number line.

Find a 2 × 2 matrix b ≠ o and b ≠ i2 such that ab = ba, where a = 1 7 0 1 . b =
riadik2000 [5.3K]
If \mathbf A is invertible, then we can simply choose \mathbf B=\mathbf A^{-1} because for any invertible matrix \mathbf X by definition we must have \mathbf{XX}^{-1}=\mathbf X^{-1}\mathbf X=\mathbf I.

We have \det\mathbf A\neq0, as

\det\mathbf A=\begin{vmatrix}1&7\\0&1\end{vmatrix}=1\times1-0\times7=1

which means \mathbf A is non-singular and has an inverse. The inverse itself would be

\mathbf A^{-1}=\dfrac1{\det\mathbf A}\begin{bmatrix}1&0\\-7&1\end{bmatrix}^\top=\begin{bmatrix}1&-7\\0&1\end{bmatrix}

Write the slope intercept form of the equation of the line through the given point with the given slope
aleksandrvk [35]

Given that,

Point = (-5,3)

Slope, m = -3/5

To find,

The slope intercept form of the equation of the line.

Solution,

The general form of equation is :

y = mx +b

We have, x = -5, y = 3

So,

3=\dfrac{-3}{5}(-5)+b\\\\3=-3+b\\\\b = 6

The equation is :

y=\dfrac{-3}{5}x+6

Hence, the required equation is y=\dfrac{-3}{5}x+6.

I want to know if mammals usually have more
DENIUS [597]

The graph that would allow the comparison between the median number of teeth for mammals and reptiles easily is a Box Plot.

<h3>Median</h3>

The median of a set of data is the midpoint of values in a data set. It shows the value that divides the data set into two halves.

<h3>Box plot</h3>
  • A box plot is a type of graph used in data analysis to visualize the distribution of numerical data and skewness by displaying the data quartiles and averages.

Box plots are also known as box and whisker plot.

  • Box plots are used to compare visually differences among different samples or groups such medians, ranges, and outliers.

Therefore, the graph that would allow the comparison between the median number of teeth for mammals and reptiles easily is a Box Plot.
