Answer:
(1,-4)
Step-by-step explanation:
Hello!
In the image attached, I graphed the Linear Equations, and the solution is at the point of intersection of the two lines.
The point is on x-value 1 and y-value -4, so the solution is (1,-4).
Answer:
26
Step-by-step explanation:
When you flip two coins, you can have 4 different outcomes:
HH
HT
TH
TT
All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.
p(both heads) = 1/4
With 105 flips, the expected number of both heads is
105 * 1/4 = 26.25
Answer: 26

The geometric mean is 9.4868
Gas is $2.53⁹ per gallon today, at that filling station
down the street from my house.
I have $10 in my pocket.
a). How much gas can I put in the car if I go there ?
b). My car gets 25 miles per gallon. How many 'miles' will my $10 buy ?
c). In Calgary (Alberta, Canada) today, gas is selling for
89¢ (Canadian) per liter. What is the percentage more or less,
compared to the price of gas down the street from my house ?
If I posted this problem on Brainly, I'd probably give it
something like 5 points for part-a, another 5 for part-b,
and 10 or 15 for part-c because in addition to math,
that part takes some research.
