Answer:
1/18
Step-by-step explanation:
We are considering that we have 2 dices with 6 faces each (so, the probability to getting any face in any dish is 1/6). To get an 11, we only have two ways to obtain it:
Dice 1= 6 and Dice 2 =5 or Dice 1= 5 and Dice 2 =6
So, the probability of the event is given as:
P(Dice1=5 ∧ Dice2=6) ∪ P(Dice1=6 ∧ Dice2=5) = P(Dice1=5) x P(Dice2=6) + P(Dice1=6) x P(Dice2=5) = 1/6 x 1/6 + 1/6 x 1/6 = 1/36 + 1/36 = 2/36 = 1/18.
As 1/18 = 0,055, and 0,055 > 0,05, we consider the event as not significative (according to the definition of significance in the sentence).

Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

Which inverse operation is needed to isolate the variable in the equation r + 8.9 = 17.4?
Group of answer choices
Add 8.9 to both sides.
Subtract 8.9 from both sides.
Add 17.4 to both sides.
Subtract 17.4 from both side
Answer:
Subtract 8.9 from both sides.
Step-by-step explanation:
When isolating variables, we need to change the parity of the number or value we are taking away. If we subtract 8.9 from both sides, we will get r=8.5.
one number is three times another number, and their sum is -10. what is the smaller of the two numbers?
Let the smaller number be x .
Then the larger number = 3x
Their sum = -10
This can be written in an equation as :-
[tex]x + 3x = - 10[/tex]
[tex]4x = - 10[/tex]
[tex]x = \frac{ - 10}{ \: \: \: 4} [/tex]
[tex]x = - 2.5[/tex]
Which means :-
The value of the first number = -2.5
The value of the second number = -2.5 × 3 = -7.5
Therefore , the smaller of the two numbers is = -7.5
Answer:
let a + b = -10
where a = 3b
substitute a into the equation: a + b = -10
3b + b = -10
b = -10 / 4
b = -2.5
a = 3b
a = 3(-2.5)
a = -7.5
check:
a + b = -10
-7.5 + (-2.5) = 10
-10 = 10
b. At the circus, three adult tickets and five child tickets cost $51, and five adult tickets
and two child tickets cost $47. Which system of linear equations below can be used to
determine the price of each ticket?
Let x represent the cost of an adult ticket, and let y represent the cost of a child ticket.
Answer: x = $7, y = $6
Step-by-step explanation:
Let x be the cost of an adult ticket
Let y be the cost of a children's ticket
Translate these sentences to algebra:
At the circus, three adult tickets and five child tickets cost $51: 3x + 5y = 51
Five adult tickets and two child tickets cost $47: 5x + 2y = 47
Now we have two equations. Let's use substitution to solve.
3x + 5y = 51
3x = 51 - 5y
.: x = 17 - 5y/3
Now substitute this value of x into the second equation to find the numerical value of y:
5(17 - 5y/3) + 2y = 47
85 - 25y/3 + 2y = 47
-19y/3 = -38
-19y = -114
.: y = 6
Now find x:
x = 17 - 5y/3
x = 17 - 10
.: x = 7
So an adult ticket costs $7, and a child ticket costs $6 :)

Granola costs $3.25 per pound. Raisins cost $6.50 per pound. How many pounds of raisins can be mixed with 10 pounds of granola to make a mixture that is $4.00 per pound? pls do this immediately
You multiply (*) the pounds cost by the [tex]10[/tex] pounds when you get that amount you divide it by the cost of granola per pound that will give you [tex]4[/tex] dollars per pound.
Hope it helped!
[tex]\huge\boxed{Thanks,\;Plip.}[/tex]
We want to find and solve an equation that tells us the number of pounds of raisins that we need to add to a mixture to get to a desired price.
We will see that we need to add 3 pounds of raisins.
We know that:
Granola costs $3.25 per lbRaisins cost $6.50 per lb.If we mix M pounds of raisins with 10 pounds of granola, the total mass will be:
M + 10
The price of this will be:
M*$6.50 + (10)*$3.25
And we want the price of this mixture to e $4.00 per pound, then we have:
M*$6.50 + (10)*$3.25 = (M + 10)*$4.00
Now we need to solve the above equation for M.
M*$6.50 + $32.50 = M*$4.00 + $40.00
M*$6.50 - M*$4.00 = $40.00 - $32.50
M*($6.50 - $4.00) = $7.50
M*$2.50 = $7.50
M = ($7.50)/($2.50) = 3
M = 3
This means that we need to add 3 pounds of raisins.

Find the equation of the tangent line to the curve y= 2x2 + x-1 at the point (5, 54).
Answer: y-54=21(x-5) or y=21x-51
Step-by-step explanation:
To find the equation of the tangent line, we first want to find the derivative of the equation.
f(x)=2x²+x-1 [Power Rule]
f'(x)=4x+1
Now that we have the derivative, we use (5,54) to find the slope.
f'(5)=4(5)+1 [multiply]
f'(5)=20+1 [add]
f'(5)=21
With our slope, we can plug it into point-slope form.
y-54=21(x-5)
We can also convert this to slope-intercept form.
y-54=21(x-5) [distribute]
y-54=21x-105 [add both sides by 54]
y=21x-51
Now, we know the tangent line is y-54=21(x-5) or y=21x-51.

P = 215(1.005)t/3
The equation above can be used to model the population, in thousands, of a certain city t years after 2000. according to the model, the population is predicted to increase by 0.5% every n months. what is the value of n ?
(A) 3 (B) 4 (C) 12 (D) 36
Answer:
(D) 36
Step-by-step explanation:
0.5% = 0.5/100 = 0.005
It is given that the population (215) is predicted to increase by 0.5%. To know the value after increment, 215 has to be multiplied by (1 + 0.005) or 1.005.
In the equation P = 215(1.005)t/3, the value of t/3 has to be equal to 1 for 0.5% increase.
t/3 = 1
t = 3 years
Convert years to months.
n = 3 ⋅ 12 months
n = 36 months
The correct option is D.
Thanks!

Answer:
36

Substitute the given values A = 77 and h = 4 into the
formula A = bh. Then solve for the variable b.
Answer:
b=19.25
Step-by-step explanation:
Ok, so if you plug in 77 for A and 4 for h, you will get 77=4h. So from here, you have to divide 77 by 4, which is 19.25 and that is the answer for variable b.
What is the equation of the line that is parallel to the line defined by the equation y = 2x + 4 and goes through the point (3, 2)?
Step-by-step explanation:
Hey there!
Given;
y = 2x + 4..........(i)
The point is; (3,2). The equation of line which passes through this point is;
(y-y1) = m2(x-x1)
(y-2)= m2(x-3)........(ii)
From equation (i).
y = 2x+4
Comparing the equation with y = mx+c, we get;
Slope (m1)= 2
As per the condition of parallel lines, (m1=m2).
Therefore, m2= 2.
Now, keeping the slope of m1 in eqaution (ii)
(y-2)= 2(x-3)
y - 2 = 2x - 6
y = 2x -4
Therefore, the equation is y = 2x - 4.

Arlington High School recently installed a new black-box theatre for local productions. They only had
room for 14 rows of seats, where the number of seats in each row constitutes an arithmetic sequence starting
with eight seats and increasing by two seats per row thereafter. How many seats are in the new black-box
theatre? Show the calculations that lead to your answer.
Answer: ANSWER*0.15 (15% is 15/100 or 0.15)
Step-by-step explanation:
An arithmetic sequence is a sequence where the difference between each consecutive term is the same.
The number of seats in the new black box is 294.
What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8 is an arithmetic sequence.
We have,
Number of rows = 14
n = 14
a = 8.
d = 2
So,
The number of seats in the 14 rows is,
8, 10, 12, 14,.........
Now,
The sum of the arithmetic sequence.
= n/2 [2a + (n - 1)d ]
The number of seats in the new black box.
= 14/2 [ 2x8 + (14 - 1)2 ]
= 7 [ 16 + 26 ]
= 7 x 42
= 294
Thus,
The number of seats in the new black box is 294.
