2x + 8 = 20
2x = 20 - 8
2x = 12
x = 12/2
x = 6.....he ran 6 miles on Tuesday...also ran 6 miles on Friday
Answer:
x^3+4x^2+5x+2
Step-by-step explanation:
Answer:
1. 32
2. y=2
3. x=0.25
Step-by-step explanation:
First look at the triangle and figure out it urself.
D=t*m
d=dollar amount
t=hours
m=how much she earns per hour
Plug in the first set of numbers
$206.25=(25hr)*m
the amount she earns per hour is
$206.25/25hr = m = $8.25 per hr
So
$264=t*$8.25
264/8.25 = t
t = 32 hr
Answer: 0.42 and 5 outcomes.
Step-by-step explanation:
i guess that carlos has a fair coin and a number cube.
the probability can be calculated as the number of outcomes that we want divided the total number of outcomes.
The coin has two possible outcomes, heads and tails, then the probability of getting heads is p1 =1/2
the number cube has 6 numbers, 5 of those 6 numbers are greater than 1, then the probability of getting a number greater than 1 is p2 =5/6
the joint probability is the product of those two:
P = 1/2*5/6 = 5/12 = 0.42
The combinations that include heads and number greater than 1 are 5 combinations:
Heads and 2
Heads and 3
Heads and 4
Heads and 5
Heads and 6.
