Brian rolls a fair dice 12 times. How many times would Brian expect to roll a number greater than 4?
Brian is expected to roll a number greater than 4, 4 times
How to determine the expected row?In a fair die, we have:
Faces = 6
Faces greater than 4 = 2 i.e. 5 and 6
So, the probability to roll a number greater than 4 is:
p = 2/6
When the dice is rolled 12 times, the expected value is:
Expected = 2/6 * 12
Evaluate
Expected = 4
Hence, Brian is expected to roll a number greater than 4, 4 times

Answer:
The center of the circle is point: C=(1,5).
The radius of the circle is r=3.
Step-by-step explanation:
x² + y² -2x - 10y + 17 = 0
Find the center and radius of this circle
We have the equation
x² + y² -2x - 10y + 17 = 0
We collect like terms
x² - 2x + y² - 10y = -17
x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²
The center of the circle is point: C=(1,5).
The radius of the circle is r=3.
find out the total volume of cube _Edge Length =6 inches
Given:
The edge length of a cube = 6 inches
To find:
The volume of the cube.
Solution:
We know that, the volume of a cube is

Where, a is the edge length.
Substituting a=6 in (i), we get
[tex]V=(6)^3[/tex]
[tex]V=216[/tex]
Therefore, the total volume of the cube is 216 cubic inches.

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15

I dont want you guys to get it wrong so it is:BOn a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs $680 and a coach ticket costs $288, how many of each ticket were sold for the flight?
Answer:
30 first-class tickets were sold and 260 coach tickets were sold.
Step-by-step explanation:
Let a first-class ticket be represented by f and let a coach ticket be represented by c.
On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:
[tex]f+c=290[/tex]
The total income was $95,280. Therefore:
[tex]680f+288c=95280[/tex]
We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:
[tex]85f+36c=11910[/tex]
From the first equation, we can subtract f from both sides:
[tex]c=290-f[/tex]
Substitute:
[tex]85f+36(290-f)=11910[/tex]
Distribute:
[tex]85f+10440-36f=11910[/tex]
Simplify:
[tex]49f=1470[/tex]
So:
[tex]f=30[/tex]
From the previous equation:
[tex]c=290-f[/tex]
Substitute:
[tex]c=290-30=260[/tex]
30 first-class tickets were sold and 260 coach tickets were sold.
richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month
Answer:
His gross pay for the month is $4,509.50
Step-by-step explanation:
The commission Richard Klein earns for oil change = 3.00%
The commission he earns for tune ups = 5.00%
The commission he earns for auto parts sales = 6.25%
The minimum salary he is guaranteed = $2,450.00
The amount he brought in last month includes;
1) $2,500.00 in oil changes
2) $4,500 in tune ups
3) Sold $28,200.00 in parts
The amount he earns last month in commission are;
3/100 × 2,500 = 75 in oil changes
5/100 × 4,500 = 225 in tune ups
6.25/100 × 28,200 = 1762.5 in parts sold
The total commission = 72 + 225 + 1762.5 = 2,059.5
∴ The total commission = $2,059.5
The amount he makes as salary = $2,450.00
Richard Klein's gross pay for the month = His total pay for the month
Therefore;
Richard Klein's gross pay for the month = $2,059.5 + $2,450 = $4,509.5

radius of 3.5 cm. How much water is needed to fill 50 cups?
Use 3.14 for pi and do not round your answer.
Answer: 7693cm
Step-by-step explanation:
The volume of a cone is given as:
= 1/3πr²h
where π = 3.14
radius = 3.5cm
height = 12
Volume = 1/3πr²h
= 1/3 × 3.14 × 3.5² × 12
= 153.86cm³
Therefore, the amount of water that is needed to fill 50 cups will be:
= 153.86 × 50
= 7693cm

The average grade Jared received on 4 tests was 94. If he drops his lowest test grade of 85, what will his new average be?
A.72.75
B.76
C.89.5
D.97
Pls help TT
Answer:
total points on the 4 tests- 94x4= 376
376- 85= 291
291/3= D. 97
Answer:
D. 97
Step-by-step explanation:
x = sum of 4 test grades Jared received
[tex]\frac{x}{4} = 94[/tex]
x = 376
If he drops lowest test grade of 85, then subtract 85 from Jared's sum of all test grades:
x - 85 --> 376 - 85
= 291
Now that one of his test grades are not considered, this means there are only 3 test grades to consider.
291 must be divided by 3 to get the average:
[tex]\frac{291}{3}[/tex] = 97
The answer is D) 97
Which angle is complementary to DFE? Pls answer
Answer:
<DFA
Step-by-step explanation:
When combined (<DFA and <DFE), they'll form 90 degrees which will make them complementary
Answer:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle. When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
The complement of −135° is the angle that when added to −135° forms a right angle (90° ).

A package of mixed lettuce seeds contains 150 green lettuce seeds and 50 red lettuce seeds. What is the probability that a randomly selected seed will be a red lettuce seed? Write your answer as a percent.
Answer:
25%
Step-by-step explanation:
I used relative frequency approach
n(total number of seeds)= 150+50=200.
probability (selecting a red lettuce) = red lettuce divided by the total number of seeds.
probability (selecting red lettuce) = 50/200 = 0.25
in percentage, probability = 0.25*100= 25%✓
