Answer:
it b
Step-by-step explanation:
Solve equation [1] for the variable x [1] x = 3y - 1
// Plug this in for variable x in equation [2] [2] 8y - 2•(3y-1) = 4
[2] 2y = 2
// Solve equation [2] for the variable y [2] 2y = 2
[2] y = 1
// By now we know this much : y = 1
x = 3y-1// Use the y value to solve for x x = 3(1)-1 = 2
Answer:
A. or 4%
B. or 64%
C. 8 times
Step-by-step explanation:
The county-fair prize wheel has equally spaced sections with the following colors: 1 is golden, 2 are silver, 3 are green, 4 are blue, 6 are red, and 9 are yellow, 25 sections in total.
A. The probability of landing on gold is
or 4% as a percent.
B. If the probability of landing on yellow is 36% (or 0.36 as decimal), then the probability of not landing on yellow is
or 64% as a percent.
C. If the wheel is spun 1 time, the probabilty of landing on silver is
or 8% as a percent.
If the wheel is spun 100 times, the expected number of landing on silver is
Well put it into an equation,
j * -50 = - 11
first you would divide -50 from both sides making it
j=0.22
0.22 times -50 gives you -11
The answer A has the correct sign
