Answer:
0.01083 or 1.083%
Step-by-step explanation:
This problem can be modeled as a binomial probability model with probability of success p = 0.56.
The probability of x=13 successes (a college student being very confident their major would lead to a good job) in a number of trials of n=15 is:
The probability is 0.01083 or 1.083%.
Answer:
A) x = 12
Step-by-step explanation:
if its a right angle? then the angle in total is 90 degrees,

4x = 48
x = 12
Answer:
14 ounces of blue paint
Step-by-step explanation:
The ratio of blue to yellow is 2:7
To solve this problem we can make a proportion:
2/7=x/49
the numerator represents the blue paint, the denominator represents the yellow paint
To solve the proportion you have to cross multiply:
2*49=7*x
x=14
She needs to add 14 oz of blue paint
I hope this helps :)
Answer:
try 1 and 2 for supplementary
and 7 and 6 for vertical
Step-by-step explanation:
45(v - 7) = 2...divide both sides by 45
v - 7 = 2/45...add 7 to both sides
v = 2/45 + 7
v = 2/45 + 315/45
v = 317/45 or 7 2/45
