Answer:
Probability that the sample contains at least five Roman Catholics = 0.995 .
Step-by-step explanation:
We are given that In Quebec, 90 percent of the population subscribes to the Roman Catholic religion.
The Binomial distribution probability is given by;
P(X = r) = 
for x = 0,1,2,3,.......
Here, n = number of trials which is 8 in our case
r = no. of success which is at least 5 in our case
p = probability of success which is probability of Roman Catholic of
0.90 in our case
So, P(X >= 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8)
= 
= 56 * 
+ 28 * 
+ 8 * 
+ 1 * 
= 0.995
Therefore, probability that the sample contains at least five Roman Catholics is 0.995.
Alex can buy at most 4 pounds of tomatoes
Let:
a represent pounds of tomatoes to buy
3a represent pounds of black beans to buy
Total cost of each ingredient that can be bought = number of pounds x price per pound
Tomatoes = a x $1.60 = 1.60a
Black beans = 3a x $1.70 = 5.1a
1.60a + 5.1a = 26.80
Add similar terms
6.7a = 26.80
Divide both sides of the equation by 6.7
a = 4 pounds

the maximum height is the y-value of the vertex.
h(x) = -2x² + 20x + 48
<em> a=-2, b=20, c=48</em>
h(5) = -2(5)² + 20(5) + 48
= -50 + 100 + 48
= 50 + 48
= 98
Answer: 98 meters
RM298
reason: multiply RM4 by 10 to get RM40 and add that to RM258 to get RM298
Whether dividing constant terms or polynomials, we always have definitive terms when it comes to division. Suppose we say, 10x divided by 2. The dividend is the 10x and the divisor is the 2. In other words, the dividend is the number to be divided by the divisor, to obtain the answer called the quotient.
When dividing polynomials, your main goal is to be able to divide the dividend evenly into the <em>divisor</em>. For example, we divide x²+2x+1 by x+1. The first thing you're going to focus is, what term will completely divide the first term of the polynomial? That would be x. Why? Because when you multiply x with x+1, the product is x²+x. When you subtract this from the polynomial, the x² will cancel out. All you have to do is subtract x from 2x, yielding x. Then, you carry down the last term of the equation: +1. You do the steps again. The term that will completely divide x+1 by x+1 is 1. When you subtract the two, you will come up with zero. That means there is no remainder. The polynomial is divisible by the divisor.
