One way to find the y int is to sub in 0 for x and solve for y
10x + 9y = 45
10(0) + 9y = 45
9y = 45 ...divide both sides by 9
y = 45/9 which equals 5
Ratio of quarters to dimes.
A dime value = $0.10
A quarter value = $0.25.
Ratio of quarters to dimes = 0.25 : 0.10 = 25 : 1
And ratio of dimes to quarters will be
0.10 : 0.25 = 1:25.
We can see that 1:25 ratio is just reciprocal of 25:1.
<em>We can just say that the ratio of quarters to dimes is reciprocal of the ratio of dimes to quarters.</em>
<h3>Therefore, we can say the ratio of quarters to dimes is not same as the ratio of dimes to quarters.</h3>
when coin is flipped 5 times probability is 1/2
so coin heads comes out to be 2.5
This is a binomial distribution with a probability of success = 0.5 (fair coin).
n=10
so
mean = E[x] = np =10*0.5 =5
Answer:

Step-by-step explanation:
5(7 − 4)^2 ÷ 3 + 11.
PEMDAS says parentheses first
5(3)^2 ÷ 3 + 11.
Then exponents
5 (9)÷ 3 + 11.
Multiply and divide from left to right
45 ÷ 3 + 11
15 +11
