Answer:
15 times
Step-by-step explanation:
6 green erasers / 20 total erasers =0.3
0.3(50) = 15
The number of times a green eraser will be drawn will be 15 times.
What is the expected value?The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
A bowl contains 3 red erasers, 4 blue erasers, 6 green erasers, and 7 erasers.
The probability of getting a green eraser will be calculated as,
P = 6 / (3 + 4 + 6 + 7)
P = 6 / 20
P = 0.30
Then the expected value is calculated as,
E = 0.30 x 50
E = 15
The number of times a green eraser will be drawn will be 15 times.

Realiza estas operaciones y expresa el resultado en metros 1m-(5dm3cm) (2hm4m)+35dam (3hm6dam)+(8dam5m) (2m5dm6cm)-85cm
Answer:
126.109,63 m
Step-by-step explanation:
Por conveniencia, todas las unidades se convierten a m
1000 m = 1 km
100 m = 1hm
10m = 1 presa
1 m = 1 m
10dm = 1m
100 cm = 1 m
1000 mm = 1 m
1m- (5dm3cm) (2hm4m) + 35dam (3hm6dam) + (8dam5m) (2m5dm6cm) -85cm
= 1m- (5/10 +3/100) (2 * 100 + 4m) + 35 * 10 (3 * 100 + 6 * 10) + (8 * 10 + 5m) (2m + 5/10 + 6/100 ) -85/100
= 1 m- (0.5 +0.03) (200 + 4m) +350 (300 +60) + (80 + 5m) (2m + 0.5 + 0.06) -85/100
= 1 m- (0,53) (204 m) +350 (360) + (85 m) (2,56) -85/100
= 1 m- (108,12 m) +126000+ (217,6) - 0,85
= 126.109,63 m
For convenience all units are converted to m
1000m = 1km
100 m= 1hm
10m = 1 dam
1m= 1m
10dm= 1m
100 cm= 1 m
1000 mm= 1m
1m-(5dm3cm) (2hm4m)+35dam (3hm6dam)+(8dam5m) (2m5dm6cm)-85cm
= 1m-(5/10 +3/100) (2*100 +4m)+35*10 (3*100 +6*10)+(8*10+5m) (2m+5/10+6/100)-85/100
= 1m-(0.5 +0.03) (200 +4m)+350 (300 +60)+(80+5m) (2m+0.5+0.06)-85/100
= 1m-(0.53) (204m)+350 (360)+(85m) (2.56)-85/100
= 1m-(108.12m)+126000+(217.6)- 0.85
= 126,109.63 m

solve for y. -5(6+7y)= -5(6+y)
Answer:
y = 0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5(6+7y)=−5(6+y)
(−5) (6) + (−5) (7y) = (−5) (6) + (−5) (y) (Distribute)
−30 + − 35y = −30 + −5y
−35y − 30 = −5y −30
Step 2: Add 5y to both sides.
−35y − 30 + 5y = −5y −30 + 5y
−30y −30 = −30
Step 3: Add 30 to both sides.
−30y − 30 + 30 = −30 + 30
−30y = 0
Step 4: Divide both sides by -30.
−30y /−30 = 0 /−30

Answer:
3a. yes
3b. y= 75x
3c. 600 mi
3d. 10 inches
Step-by-step explanation:
3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.
3b: y would equal the amount of inches multiplied by 75, so y=75x
3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles
3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches

a − 3b = −5
3a + 2b = 5
a. 5/3
b. -2
c. -3/5
d. 1
Answer:
5/11, 20/11
Step-by-step explanation:
a − 3b = −5
-3b = -a - 5
b = 1/3a + 5/3
3a + 2(1/3a + 5/3) = 5
3a + 2/3a + 10/3 = 5
11/3a + 10/3 = 5
11/3a = 5/3
a = 5/11
a - 3b = -5
5/11 - 3b = -5
-3b = -60/11
b = 20/11

9514 1404 393
Answer:
10
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((7 -1)^2 +(12 -4)^2) = √(6^2 +8^2) = √(36 +64) = √100
d = 10
The distance between P and Q is 10.
