Answer:

B)\:\frac{53}{20}

Step-by-step explanation:

\left|-\frac{4}{5}-\frac{1}{10}\right|+\left|-\frac{3}{4}+\frac{5}{2}\right|

\left|-\frac{4}{5}-\frac{1}{10}\right|=\frac{9}{10}

\left|-\frac{3}{4}+\frac{5}{2}\right| =\frac{7}{4}

\frac{9}{10}+\frac{7}{4}

\frac{53}{20}

Triangle ABC has vertices A(–2, –3), B(–5, –3), and C(–4, –2). The triangle is rotated 90° counterclockwise around the origin.
Ulleksa [173]
The rule for this rotation is (x, y) converted into (-y, x). So, to find the answer you would make the y negative and switch the values in the ordered pair. A would be (3, -2), B would be (3, -5), and C would be (2, -4). So, your answer would be B. Hope this helps!

For which distributions is the median the best measure of center? Select each correct answer. Y 20 30 18 25 16 20 14 15+ 12 10+
AURORKA [14]

Answer:

The median is the best measure of center for distributions C and D.

Step-by-step explanation:

The <u>median</u> is the best measure of center for skewed distributions or distributions with outliers because it is a <u><em>robust</em></u> statistic, meaning that outliers and skewed data have <em>little effect </em>on the median.

Meanwhile, the <u>mean</u> is a good measure of center for symmetric distributions since it is <u><em>non-robust</em></u>.

Answer A has a roughly symmetric distribution, and answer B has a uniform distribution.

Answer C has a left-skewed distribution, and answer D seems to have a right-skewed distribution (since the right tail is longer than the left tail).

Therefore, the <u>median</u> would be the <u><em>best measure of center</em></u> for choices C and D.

Complete the equation of the line through (2,-2) and (4,1).
scoundrel [369]
Slope formula : (y2 - y1) / (x2 - x1)
(2,-2)....x1 = 2 and y1 = -2
(4,1)...x2 = 4 and y2 = 1
now we sub into the slope formula and solve for the slope
slope = (1 - (-2) / (4 - 2) = (1 + 2) / 2 = 3/2

now we use y = mx + b
slope(m) = 3/2
use either of ur points....(4,1)...x = 4 and y = 1
now sub into y = mx + b formula and find b, the y int
1 = 3/2(4) + b
1 = 6 + b
1 - 6 = b
-5 = b

so ur equation is : y = 3/2x - 5 <==

A local hamburger shop sold a combined total of 628 hamburgers and cheeseburgers on Thursday. There were 72 fewer cheeseburgers
lys-0071 [83]

Answer:

278 cheeseburgers and 350 hamburgers sold on Thursday

Step-by-step explanation:

To confirm that these combined equal 628 we can add them together using the equation 278 + 350. Once confirm that these both equal 628 when combined, we can find the difference between the 350 hamburgers and 278 cheeseburgers by subtracting one from the other using the equation, 350 - 278. When you do that, you will get a difference of 72 which means that there were 72 fewer cheeseburgers sold than hamburgers.

(sorry if this is confusing, I'm not good at explaining things)

Write an inequality for "x".
raketka [301]

Answer: X<-3

Step-by-step explanation: I got this becuase the open dot with the arrow point left means anything lower than -3, if it was closed (filled in) dot, it would be anything -3 and lower. But since it’s not, it’s just anything lower than -3.
