Answer:

\frac{1}{8} chance or 12.5% chance

Step-by-step explanation:

2 male <em>percussionists</em>

2 female <em>percussionists</em>

3 male <em>woodwinds</em>

<u>2 </u><u>female</u><u> </u><u><em>woodwinds</em></u>

4 male <em>brass players</em>

3 female <em>brass players</em>

We're looking for a female <em>woodwind. </em>Now there is only 2 of them so we get the female woodwinds out of all the jazz band members or \frac{2}{16} or \frac{1}{8} or 12.5% chance.

PLZ HELP 235 people are at RSM summer camp. There are 35 more boys than girls, and 70 fewer adults than girls. How many people o
Olin [163]

Answer:

number of girls = 90

Number of boys = 125

Number of adults = 20

Step-by-step explanation:

Total people at the summer camp= 235

Let

number of girls=x

Number of boys = x + 35

Number of adults = x - 70

Total people at the summer camp= number of girls + Number of boys + Number of adults

235 = x + (x+35) + (x - 70)

235 = x + x + 35 + x - 70

235 = 3x - 35

Add 35 to both sides

235 + 35 = 3x

270 = 3x

Divide both sides by 3

x= 270/3

= 90

x = 90

number of girls= x = 90

Number of boys = x + 35

= 90 + 35

= 125

Number of adults = x - 70

= 90 - 70

= 20

Total = 90 + 125 + 20

= 235

A police car's siren operates at a frequency of 2,000 Hz. What frequency would a stationary listener observe if the police car i
SpyIntel [72]

we can use formula

f_L=f_s(\frac{v_a-v_p}{v_a+v_p} )

where

fL is listener frequency

fs is siren frequency

va is the speed of sound in air

vs is police car speed

so, we have

f_s=2000Hz

v_a=345m/s

v_p=65mph

now, we can change it into m/s

v_p=65*\frac{1609}{3600}m/s

v_p=29.05139m/s

now, we can plug it

f_L=2000(\frac{345-29.05139}{345+29.05139} )

f_L=1689.33263Hz..............Answer

dimulka [17.4K]
After a reflection across line L1, x = 2, the afterimage is
Z' (2 + (2-1) ,1) = Z' (3, 1)
After a reflection across the line L2, y-axis, the afterimage is
Z'' (3, 0 + (0 - 1) = Z'' (3, -1)<span />

Lesson 3 homework practice mean absolute deviation
Natali5045456 [20]
Assuming that am supposed to calculate the the mean absolute deviation of 
1,2,3,4,5,6,7
mean absolute deviation is calculated by first calculating the mean;
 (1+2+3+4+5+6+7) =28/7
                               = 4
Then, find the absolute value (the difference between each value in the data and the mean) (x-μ)
 = -3,-2,-1,0,1,2,3
Absolute values= 3,2,1,0,1,2,3
Then we find the mean of the values,
3+2+1+0+1+2+3 = 12
                           = 12/7
                           = 1.7143
Therefore, the mean is 4, and the Mean absolute deviation is 1.7143
