Answer:
0.7727 = 77.27% probability that it is small or green
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
11 large + 11 small = 22 total marbles = 22 total outcomes
11 small marbles + 6 green large marbles = 17 desired outcomes.
What is the probability that it is small or green?
[tex]p = \frac{17}{22} = 0.7727[/tex]
0.7727 = 77.27% probability that it is small or green

Determine which equation has the same solutions as the given equation.
x2 − 10x − 11 = 0
A.
(x − 10)2 = 36
B.
(x − 5)2 = 36
C.
(x − 5)2 = 21
D.
(x − 10)2 = 21
I just want to mention that the question is wrongly written!
it's meant to be x² − 10x − 11 = 0 and not x2 − 10x − 11 = 0
and so the other equations!
Answer:
The answer is B: (x − 5)² = 36
Step-by-step explanation:
by solving the equations using the quadratic formula we found:
the solutions for x² − 10x − 11 = 0 | x = 11, -1
the solutions for A | x = 16, 4
the solutions for B | x = 11, -1
the solutions for C | x = [tex]\sqrt{21} +5[/tex], [tex]-\sqrt{21}+5[/tex]
the solutions for D | x = [tex]\sqrt{21}+10, -\sqrt{21}+10[/tex]
the given equation: x² − 10x − 11 = 0 and the equation B: (x − 5)² = 36 have the same solutions
Therfore B is the correct answer
50 POINTS! QUICKLY Are the pairs of variables x and y the solutions to the equation x^2–2y=7?
1. (5,8)
2. (-1,-3)
3. (-4,-11.5)
4. (1.2, -2.78)
These are all yes and no questions!
Hi there!
[tex]\large\boxed{(5,8) \text{ and } (1.2, -2.78)}}[/tex]
We are given the equation:
x² - 2y = 7
To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:
1. (5)² - 2(8) = 7
25 - 16 = 9 ≠ 7. This is NOT correct.
2. (-1)² - 2(-3) = 7
1 + 6 = 7. This is correct.
3. (-4)² - 2(-11.5) = 7
16 + 23 = 39 ≠ 7. This is NOT correct.
4. (1.2)² - 2(-2.78) = 7
1.44 +5.56 = 7. This is correct.
Thus, only 1 and 4 are the correct answers.
No yes no yes

circumference of circle 132cm find the area of circle is
Answer: 1386 sq.cm.
Step-by-step explanation:
2Pi r= 132
2 * 22/7 * r = 132
r = 21
Area = pi * r * r
= 22/7 * 21 * 21
= 1386 sq.cm.

Answer:
Step-by-step explanation:
if one point is located at (-5,3) and another point is located at (7,-4). find the distance between the points. round to the nearest tenth.
Answer:
13.9
Step-by-step explanation:
Use the distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\[/tex]
The square root of 193 rounded to the nearest tenth is 13.9.

Answer:
[tex]\boxed {\boxed {\sf 3 \ pounds \ of \$4 \ candy}}[/tex]
[tex]\boxed {\boxed {\sf 2.5 \ pounds \ of \$3.50 \ candy}}[/tex]
Step-by-step explanation:
Let's create a system of equation. First, define the variables. One type of candy is x and the other is y.
Now, create 2 equations, one for the weight and one for the price.
[tex]x+y=5.5[/tex]
[tex]4x+3.5y=20.75[/tex]
The first equation represents the mixture of both types of candy that weighs 5.5 pounds. The second represents the prices of the candy and the mixture.
Next. solve for the variables using substitution. Isolate a variable in the first equation. Let's isolate y by subtracting x.
[tex]x-x+y=5.5-x\\y= 5.5-x[/tex]
Now, we know what y is equal to, so we can substitute it into the second equation.
[tex]4x+ 3.5 (5.5-x)= 20.75[/tex]
Distribute the 3.5. Multiply each term by 3.5
[tex]4x+(3.5*5.5)+(3.5*-x)[/tex]
[tex]4x+19.25-3.5x= 20.75[/tex]
Combine like terms on the right side.
[tex]0.5x+19.25=20.75[/tex]
Subtract 19.25 from both sides of the equation to isolate the variable.
[tex]0.5x+19.25-19.25=20.75-19.25[/tex]
[tex]0.5x= 1.5[/tex]
Divide both sides by 0.5.
[tex]\frac {0.5x}{0.5}= \frac{1.5}{0.5}\\x=3[/tex]
Now we can substitute x back into the first equation and solve for y.
[tex]x+y=5.5\\3+y=5.5[/tex]
Subtract 3 from both sides to isolate the variable.
[tex]3-3+y=5.5-3\\y=2.5[/tex]
There was 3 pounds of the $4 candy and 2.5 pounds of the $3.50 candy.

If an equilateral triangle has a height of 8 metres find the length of each side. Round your answer to 2 decimal places.
Answer:
9.24 m to 2 DP's.
Step-by-step explanation:
Consider the right triangle formed from a side , altitude and 1/2 the base.
By pythagoras:
x^2 = 8^2 + (0.5x)^2 where x is the length of each side.
x^2 - 0.25x^2 = 64
0.75x^2 = 64
x^2 = 64/0.75 = 85.3333.
x = 9.2376 m.

Rohan bought an almirah for Rs 15,600 and spent Rs 400 on its transportation. The total C.P is __________
From the question,
Rohan bought an almirah for =Rs.13600= cost price
Transportation cost =Rs.400
The total cost price of almirah =Rs.(13600+400)
The total cost price of almirah =Rs.(13600+400)=Rs.14000
He sold it for =Rs.16800= selling price
By comparing SP and CP=SP>CP, so there is a gain
Gain=SP−CP
=16800−14000
=Rs.2800
Gain %={(gain/CP)×100}
={(2800/14000)×100}
={2800/140}
=20%

The average of 15 test scores is 80. If the average of first eight test scores is 65 and that of the last eight test scores is 70, then the eighth score is 80.
True or False?
Answer:
FalseStep-by-step explanation:
The average of 15 test scores is 80.
The total is:
15*80 = 1200The average of first eight test scores is 65.
The total is:
8*65 = 520The average of last eight test scores is 70.
The total minus 8th score is:
8*70 - 80 = 480The sum gives us the total of 15 scores:
520 + 480 = 1000 < 1200The answer is FALSE

(1) Here is a diagram representing a base-ten number. The large rectangle represents a unit that is 10 times the value of the square. The square represents a unit that is 10 times the value of the small rectangle. If the large rectangle represents 1,000, what number is this? *
Answer:
Square = 100
Small rectangle = 10
Step-by-step explanation:
Large Rectangle = 1000
If the square represents ten times the large rectangle. Then divide by 10.
Square = 100
Then divide by 10 again.
100÷10=10
