Answer:

y = 1

Step-by-step explanation:

5(2y−3)−4y=8−2y−15

10y - 15 - 4y = 8 - 2y - 15

6y - 15 = -2y -7

6y = -2y + 8

8y = 8

y = 1

What is the mean absolute deviation for 9, 7, 6, 8, 7, and 5? (2 points) a 1 b 2 c 6 d 7

Burka [1]

Answer: a. 1

Step-by-step explanation:

Given data: 9, 7, 6, 8, 7, and 5.

Mean absolute deviation: $MAD=\dfrac1n\sum^n_{i=1}|x_i-m|$ , where m = mean

mean (m) = $\frac{\text{Sum of values}}{\text{Number of values}}$

$=\frac{42}{6}\\\\=7$

Now, $MAD=\dfrac{|9-7|+|7-7|+|6-7|+|8-7|+|7-7|+|5-7|}{6}$

$MAD=\dfrac{2+0+1+1+0+2}{6}$

$MAD=\dfrac{6}{6}$

$MAD=1$

Hence, the mean absolute deviation=1

Thus correct option is a. 1

Answer:

$let \: area \: be \: a, \: height \: be \: h, \: base \: be \: b \\ a = \frac{1}{2} bh \\ a + \delta \: a = \frac{1}{2} \times (b + \delta \: b)(h + \delta \: h) \\ a + \delta \: a = \frac{1}{2} (bh + b\delta \: h + h\delta \: b + 0) \\ \delta \: a = \frac{1}{2} (b\delta \: h + h\delta \: b) \\ \frac{\delta \: a}{a} = \frac{b\delta \: h + h\delta \: b}{bh} \\ \frac{\delta \: a}{a} = | \frac{\delta \: h}{h} | + | \frac{\delta \: b}{b} | \\ \frac{\delta \: a}{ 90} = \frac{0.5}{15} + \frac{0.5}{6} \\ \delta \: a = 10.5 \: {cm}^{2}$
