Your answer is D since 53 is the total amount of bottle caps and only 2 of them are marked. so that will leave you with a 2/53 chance of getting the prize.
We have such system of eq
First lets solve second eq
7x=21 /:7 divide both sides by 7
x=3
Now we can substitute it to first equation
9x-2y=19
9*3-2y=19
27-2y=19 /-27 subtract 27 both sides
-2y=-8 /:(-2) divide both sides by -2
y=4 - its the answer
What’s the area of the semi circles and square?
Answer:
74/15
Step-by-step explanation:
x - 3 =
to remove fractions multiply each side of equation by 40
3/4x(40) - 3 = 7/10(40)
120/4x - 120 = 280/10
simplify:
30x - 120 = 28
add 120 to each side to get:
30x = 148
x = 148/30 or 74/15 simplified
Answer:
1/38
Step-by-step explanation:
Given :
Probability = required outcome / Total possible outcomes
Total possible outcomes = total Numbe rod sections = 38
Required outcome = number of 1's on the entire section = 1
Hence, the probability of spinning a one equals :
P(spinning a 1) = 1 / 38
