If the probability of success is 0.03. Then the expected value of the raffle will be 3.
What is binomial distribution?Binomial distributions consist of n independent Bernoulli trials.
The expected value X will be given below.
E(X) = np
A raffle at a local fair has tickets for purchase for $10 each.
There are 100 total tickets in the raffle.
The tickets are shuffled, then 3 are selected to win a $100 prize.
Then the probability of success will be
p = 3/100
p = 0.03
Then the expected value of the raffle will be
n = 100
Then we have
E(X) = np
E(X) = 100 x 0.03
E(X) = 3

Is 5 inches bigger than 1/3 if a foot
Answer:
Yes
Step-by-step explanation:
1 foot= 12 inches
12÷3=4
This means that 1/3 of a foot is 4 inches
5 inches is larger than 4 inches
Answer:
Yes
Step-by-step explanation:
1/3 is 0.33333333333333 foot which = 4 inches.
Formula: multiply the value in feet by the conversion factor '12'.
So, 0.33333333333333 foot = 0.33333333333333 × 12 = 4 inches.
The other value is 5 inches.
5 inches is greater than 4 inches.

f (x) =-3x+25; Find f(x)=52
Simplifying
-3x + 25 = 52
Reorder the terms:
25 + -3x = 52
Solving
25 + -3x = 52
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-25' to each side of the equation.
25 + -25 + -3x = 52 + -25
Combine like terms: 25 + -25 = 0
0 + -3x = 52 + -25
-3x = 52 + -25
Combine like terms: 52 + -25 = 27
-3x = 27
Divide each side by '-3'.
x = -9
Simplifying
x = -9

Answer:
2 seconds
Step-by-step explanation:
The variable S represents the height off the ground, so we can substitute in the value 140 for it:
[tex]140 = 80t - 5t^{2}[/tex]
We can add [tex]5t^{2}[/tex] to both sides and subtract [tex]80t[/tex] so the equation is in standard form:
[tex]5t^{2} - 80t + 140 = 0[/tex]
Every term has five as a factor, so we may divide both sides of the equation by 5.
[tex]t^{2} - 16t + 28 =0[/tex]
To factor this, we need two numbers that multiply to 28 and sum to -16. These numbers are -14 and -2, so these are the two factors:
[tex](t-14)(t-2)=0[/tex]
We can see that when t = 14 or 2, the whole left has a value of zero, so they are the two answers.
We are asked when the rocket first is at 140m, and 2 seconds is before 14, so the answer is 2 seconds.

A (16p.7p) + 53p
B (53p • 16p): 7p
C (16p + 7p): 53p
D (53p + 16p) + 7p
The expression 53p + (16p+7p) is equivalent to expression (53p + 16p) + 7p
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 53p + (16p + 7p)
Fifty three times of p plus sixteen p plus seven p.
In the given expression p is the variable and plus is the operator.
We need to find the equivalent expression.
Equivalent expressions are expressions that work the same even though they look different.
53p + (16p + 7p)
76p
(53p + 16p) + 7p is also equal to 76p
Hence, the expression 53p + (16p+7p) is equivalent to expression (53p + 16p) + 7p

At a tournament, the bowling league is providing 160 sandwiches for its members. The table shows the number of different types of sandwiches that were ordered. The ratio of turkey sandwiches to roast beef sandwiches is 5:3. Drag the numbers to complete the table.
Answer: See below
Step-by-step explanation:
The total number of ordered sandwiches is 160
The total number of Turkey Sandwiches is 80
The ratio of Turkey to Roast Beef is 5:3
So from this, 5 times of a value is 80
So 5x = 80
And x = 16
So the Roast beef sandwiches are 16×3=48
Therefore, the table is:
Sandwich type Number
Turkey 80
Roast Beef 48

Answer:
Problem 1. Pikachu is level one and he wants to become level two. But he has to train, so he discovers that his attack swift gives him 1.176 points of experience. But he needs 2.352 points to reach the next level.
How many times does he have to perform the swift attack?
a)1 b)2 c)3 d)4
Problem 2. Snorlax needs to reach level 10 to enter the pokemon gym. But he is currently level 4. However, he discovers that his attack smash gives him .392 experience points and he needs 2.352 to reach level 10. How many times does he have to perform smash?
a)4 b)5 c)6 d)7
Step-by-step explanation:
This is a very easy question if you think the opposite.
1.- The opposite of multiplication is division. So with this knowledge, we can form any amount of problems we want we just need to combine the numbers with our product which is 2.352.
2.- So in the first place, let's make it easy. If we divide 2.352 in 2 then we are going to obtain. 1.176 as a product. Then we combine our product with our divisor and we can multiply them to find our initial product which was 2.352.
3.- In the second place we go more complicate, we divide 2.352 in 6 and we will obtain. .392 then we combine .392 with 6 to multiply them and we obtain back our initial objective. Can you see? it is the easiest thing to do.
4.- We then look for scenarios to put these two processes and we will find our problems.
Problem 1. Pikachu is level one and he wants to become level two. But he has to train, so he discovers that his attack swift gives him 1.176 points of experience. But he needs 2.352 points to reach the next level.

Hello I was wondering What is 7% of 150
Answer:
10.5
Step-by-step explanation:
rounding to the nearest hundredth percent. if the cost of an item is $16.90 the selling price is $25.60. The dollar markup is $8.70. what is the percent markup on cost ?
the selling price is 25.60, the cost was 16.9, that means 25.6 - 16.9 = 8.7, so the item's price has been bumped up by 8.7 bucks, which is the markup, how much is that of 25.6?
worded differently, if we take 16.9(cost) to be the 100%, what is 8.7 off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 16.9 & 100\\ 8.7& x \end{array} \implies \cfrac{16.9}{8.7}~~=~~\cfrac{100}{x} \\\\\\ 16.9x=870\implies x=\cfrac{870}{16.9}\implies x\approx 51.48[/tex]
