This spinner will be spun twice.What is the probability of spinning an odd number both times?
The Probability of spinning an odd number both times is [tex]\dfrac{1}{2}[/tex].
The formula of ProbabilityProbability is calculated by the ratio of favourable outcomes and the total number of outcomes.
How to find the probability?The total number of outcomes of spinning numbers will be 4 that is 1,2,3,4.
And in which the odd numbers are 1,3.
Therefore the favourable outcome of spinning an odd number both the times will be 2.
Then, the probability will be
[tex]P=\dfrac{2}{4} \\P=\dfrac{1}{2}[/tex]
So, the probability of spinning an odd number both times will be [tex]\dfrac{1}{2}[/tex].

Be sure to include the correct unit in your answer.
65 yd
13 yd
18 yd
Answer:
The area is
[tex]72yd^{2}[/tex]
(square yards)
Step-by-step explanation:
Explanation:
In the given triangle a base 24 y d and the corresponding height 6 y d
is given, so to calculate the area we can use:
A = 1 2× b × h
If we substitute thegiven numbers we get:
A = 1 2 × 24 × 6 = 12 × 6= 72
The units of base and height are the same (yards), so the calculated area is in y d 2 (square yards)
Answer: The area of the given triangle is 72 square yards.
Mama Mia restaurant used \dfrac12 2 1 start fraction, 1, divided by, 2, end fraction of their mozzarella cheese making pizza and the remaining 646464 ounces making pasta. How many pounds of mozzarella cheese did Mama Mia start with?
Answer:
8 pounds
Step-by-step explanation:
CORRECT: the remaining 64 ounces making pasta.
Assuming 'x' be the total ounces of mozzarella
we know that
making pizza : (1/2)*x => x/2
therefore, making pasta: [x-x/2] => (2x-x)/2 => x/2
making pizza=making pasta=x/2
Thus, (x/2)=64
x=(64)(2)
x=128 ounces
Note that 1 ounces=0.0625 pounds
then, 128 ounces*0.0625=8 pounds
Thus, Mama Mia started with 8 pounds of mozzarella cheese

In the basketball game, the Buffalo made a total of 25 shots. Some of the shots are 2- point shots while others are 3- point shots. If the Buffalo scored a total of 57 points, how many were 2-point shots?
Let's let x be the number of 3-point shots made.
Let's let y be the number of 2-point shots made.
So, then we have:
x+y = 25
And we have
3*x + 2*y = 57
So, we can solve this by substitution. Solving the first equation for x:
x=25-y
Now, plugging into the second equation:
3*(25-y) + 2*y = 57
Simplifying:
75-3y+2y = 26
75-57 = y
y=18
So the player made 18 2-point should and 7 3-point shots for a total of 57 points!

Fuel x costs $2 per gallon and fuel y costs $3 per gallon. You have at most $18 to spend on fuel. Write a system of linear inequalities to represent this situation.
The answer is :
x + y ≤ 14
2x + 3y ≤ 18
The inequality for the given statement will be equal to x +y ≤ 18 or,
2x + 3y ≤ 18.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.
As per the given information in the question,
The price of fuel x = $2/gallon
The price of fuel y = $3/gallon
Total money to spend on fuel = $18
Then, the inequality in this situation will be,
x +y ≤ 18 or,
2x + 3y ≤ 18.

Find a monic quartic polynomial f(x) with rational coefficents whose roots include
x=1-sqrt2, and x=2+sqrt5. Give your answer in expanded form.
Answer:
The polynomial hose roots are :
x = 1 - √2 and
x = 2 + √5
Is
x² - (3 + √5 + √2)x + 2 + √5 - 2√2 -√10 = 0
Step-by-step explanation:
The roots of the equation are
x = 1 - √2 and
x = 2 + √5
(x - 1 + √2)(x - 2 - √5) = 0
x²- 2x - x√5 - x + 2 + √5 + x√2 - 2√2 - √10 = 0
x² - (3 + √5 + √2)x + 2 + √5 - 2√2 -√10 = 0
This is the expanded form
