Answer:

the probability that randomly selected applicants over 10 years of experience is 0.6791

Step-by-step explanation:

The computation of the probability that randomly selected applicants over 10 years of experience is as follows:

Total would be

= 187 have 10 + years experience

Now

P(graduate | 10+) = (graduate and 10+ years experience) ÷ (10 + years of experience)

= 127 ÷ 187

= 0.6791

Hence, the probability that randomly selected applicants over 10 years of experience is 0.6791

Answer:

D

Step-by-step explanation:

7 - z = 3 + z + 4 - 2z

7 - 3 - 4 = z - 2z + z

0 = 0 (Infinitely many solutions)

5(a + 4) - 15 = -5(a - 1)

5a + 20 - 15 = -5a + 5

5a + 5a = 5 - 20 + 15

10a = 40

10a/10 = 40

a = 4

(one solution)

-2d + 4d - 4 = 5 + 3(d - 3)

2d - 4 = 5 + 3d - 9

2d - 3d = 5 - 9 + 4

- d = 0

d = 0

(one solution)

-11(n - 2) + 8(n + 1) = -3(n + 10)

-11n + 22 + 8n + 8 = -3n - 30

-11n + 8n + 3n = -30 - 22 - 8

0 = -60

(no solutions)

Answer:

1 = 7x=42 (divide both sides by 7)

7x/7 =42/7

x=6

2.=9y=81 (divide both sides by 9)

9y/9y= 81/9

y=9

3.= –40=8a (divide both sides by 8)

–40/8= 8a/8

a=5

4.=y divided 11=12

y=11 multiplied by 12

y= 132

5.= –15y=135( divide both sides by –15)

–15y/–15=135/–15

y= –9

6.= 17p=51(divide both sides by 17)

17p/17=51/17

p=3

7.= –65= –13w (divide both sides by 13)

–65/–13=–13w/–13

w=5

8.=y/–2=4

(cross multiply)

y/–2=4/1

4 multiplied by –2= –8

therefore:y= –8

I HOPE THIS HELPED :)

Answer:

a) 7x=42

Step-by-step explanation

use the co-efficient of the unknown to divide both sides

7x=42

7x/7=42/7

x=6

9y=81

9y/9=81/9

y=9

-40=8a

is the same thing as

-8a=40

-8a/-8=40/-8

a=-5

y+11=12

y=12-11

y=1

-15y=135

-15y/-15=135/-15

y=9

17p=51

17p/17=51/17

p=3

-65=-13w

13w=65

13w/13=65/13

w=5

y/-2= 4

cross multiply y=-8

Answer:

[tex]y = \frac{5}{2}x + 8[/tex]

Step-by-step explanation:

(-2 , 3 ) ; (0 , 8)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

          [tex]= \frac{8-3}{0-[-2]}\\\\=\frac{5}{0+2}\\\\=\frac{5}{2}[/tex]

   m = 5/2 ; (0 , 8)

Equation: y -y1 = m(x -x1)

               [tex]y - 8 =\frac{5}{2}(x - 0)\\\\y - 8 =\frac{5}{2}x\\y = \frac{5}{2}x + 8[/tex]

Good job! :)

Answer:

[tex]y=-314x-1261[/tex]

Step-by-step explanation:

When we are writing an equation we have to put it in slope-intercept-form [tex]y=mx+b[/tex]. We already know the slope it's -314, we replace m with the slope. Now we have to find b which is the y-intercept. So what we have to do is plug in the ordered pair into the equation. -4 for x and -5 for y.

[tex]y=mx+b\\-5=-314(-4)+b[/tex]

Now we solve

[tex]-5=-314(-4)+b\\-5= 1256+b\\b=-1261[/tex]

So now that we know everything we need we plug in and....

[tex]y=mx+b\\y=-314x-1261[/tex]

we've got our equation!

Answer:

The line slants upward, so the slope is positive.

A)11

B)0.1875

Step-by-step explanation:

2x+7=15

2x+7-7=15+7

2x=22

2x/2=22/2

3.4x+8=-12

3/4x+8-8=-12+8

3/4x=-4

3/4divided by 3/4=-4 divided by 3/4

x=0.1875

Answer:

1.8ft/s

Step-by-step explanation:

Using the formula for calculating Speed as shown:

Speed = Distance/Time

Time = Distance/Speed

t = d/s

Given

d1 = 25 foot

s1 = 3ft/s

d2 = 15ft

Required

s2

Using the formula;

d1/s1 = d2/s2

s2 = s1d2/d1

s2 = 3*15/25

s2 = 45/25

s2 = 1.8ft/s

Hence the rate of change between the bottom of the ladder and the wall is 1.8ft/s
