Six students measure the acceleration (in meters per second per second) of object in free fall. The measured values are shown. T

Sunny_sXe [5.5K]

The measured data is
x=[10.56, 9.52, 9.73, 9.80, 9.78, 10.91].

Calculate the mean.
m = (10.56+9.52+9.73+9.80+9.78+10.91)/6 = 10.05

Calculate the deviations from the mean.
k = x - m
= [0.51, -0.53, -0.32, -0.25, -0.27, 0.86]

Calculate the absolute deviation from the mean.
$d= \frac{1}{6} | (0.51-0.53-0.32-0.25-0.27+0.86) | = |1.184\times10^{-15}| \approx 0$

$32\ ounces\ cost\ 6,72\$\\
1\ ounce\ costs\ x\\\\
Making\ ratio:\\
32-6,72\\
1-x\\\\\ Cross\ multiplication:\\
32x=6,72*1\\
32x=6,72\ \ \ \ | divide\ by\ 32\\
x=0,21\$\\\\

Find the area of the shaded figure in the diagram below. Use 3.14 for π and round your answer to the nearest hundredth.

kirill [66]

Answer:

Step-by-step explanation:

diameter of 1 circle = 21.3/3= 7.1

radius of 1 circle= 7.1/3=3.55

area of 1 circle =πr^2=3.14× (3.55)^2=39.57

area of 3 circle= 39.57×3=118.72

therefore,area of shaded portion= area of 3 circle =118.72

Me ayudan con esa ecuacion por sustitucion con la comprobacion pliss

attashe74 [19]

<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5

1/5x+3y/2=2 => (1/5)x + (3/2)y = 2

Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:

2x + 15y = 20

</span><span>Multiply the 1st equation by -1:

-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.

Solution is (10,0).
