Answer:
10.34% probability that you both pick chocolate
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, it is not important if you or your friends picks first. So we use the combinations formula to find the number of desired and total outcomes.
Combinations Formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
10 are filled with chocolate, and we want to pick 2. So
Total outcomes:
The box has 30 chocolates, and 2 are picked, so:
Probability:
10.34% probability that you both pick chocolate
Both of those angles are 45
Look up 90 45 45 triangle:)
M=2j
m+j=480
Substitute 2j for m;
2j+j=480
3j=480
j=160
Jen earns $160 per week.
m=2j
m=2(160)
m=320
Mari earns $320 per week.
Answer: For 1 it is A - f(x)=(x-2)(x+4) and for 2 it is C - y = 0.5x^2 + 1.5x − 5

Answer:
Step-by-step explanation:
Driving 55mph for two hours, he would travel 110 miles
Driving 70mph for one hour, he would travel 70 miles.
Driving 50mph for two hours, he would travel 100 miles.
Total Distance would be 280 miles.
Average speed would be (55+70+50)/3 = 58mph
If he drove 280 miles at 70mph, it would take 4 hours
Distance = Rate X Time
