What are the solutions of the equation 6x^2-x-1=0
Answer:
x=1/2 or x=-1/3
Step-by-step explanation:
6x^2-x-1=0
6x^2+2x-3x-1=0
(6x^2+2x)+(-3x-1)=0
2x(3x+1)-1(3x+1)=0
2x(3x+1)-1(3x+1)=0
(2x-1)(3x+1)=0
(2x-1)(3x+1)=0
2x-1=0
or
3x+1=0

What is the value of the expression 9/14÷(−0.6×2)?
Answer:
-0.72
Step-by-step explanation:
First we must solve what in parenthesis
-0.6 × 2 = -1.2Now we must convert [tex]\frac{9}{14}[/tex] to a whole number
To do that simply divide 9 by 14 and that come out as
0.64285714285Round to the tenths= 0.6
Now multiply
-1.2 × 0.6 = -0.72A rectangle has a length represented by the function f(x) and a width represented by g(x).

It takes Imani seven hours to dig a 10 ft by 10 ft hole. Stefan can dig the same hole in five hours. If they worked together how long would it take them
Answer:
2 hours and 44 min. or 2.7273 hours
Step-by-step explanation:
Ryan: 1 hole per 5 hours
Castel: 1 hole per 6 hours
x = time if working together then
x(1/5 + 1/6) = 1
x(6 + 5) = 30
11x = 30
x = 30/11
x = 2.7273 hours

The area of the smallest box that a circular pizza will fit into = 1661 squared cm.
What is Area of Circle?
The area of a circle is the amount of space enclosed within the boundary of a circle. The region within the boundary of the circle is the area occupied by the circle.
The circular pizza requires the same amount of dough as the square pizza.
Area of the square pizza =40 cm * 40 cm
= 1600 [tex]cm^{2}[/tex].
Area of circle= [tex]\pi\; r^{2}[/tex]
1600 = 3.14 *[tex]r^{2}[/tex]
[tex]r^{2}[/tex] = 510
r= 22.58
r = 23 cm approx.
Area of circle= [tex]\pi\; r^{2}[/tex]
= [tex]3.14 * (23)^{2}[/tex]
= 1661.06 squared cm

Answer:
The triangles are not similar
Step-by-step explanation:
You can make a ratio with the corresponding sides of the triangles. When triangles are similar, the ratios are equal.
These will be:
ED:BA = EF:BC = FD:AC
Now, to substitute the numbers and check whether the ratios are equal:
3/8 = 2/5
Already, we see that these ratios are not equal, therefore the two triangles aren't similar.
Which expression shows the factors of 9x2 3x − 2? a. (3x − 1)(3x − 2) b. (3x 1)(3x − 2) c. (3x 2)(3x − 1) d. (9x − 2)(x 1)
The complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)
How to determine the complete factorization?The expression is given as:
9x² + 3x - 2
Expand the equation
9x² + 3x - 2 = 9x² + 6x - 3x - 2
Factorize the expression
9x² + 3x - 2 = 3x(3x + 2) - 1(3x + 2)
Factor out 3x + 2
9x² + 3x - 2 = (3x - 1)(3x + 2)
Hence, the complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)

How can logistic regression be used as a classifier? Group of answer choices Logistic regression can be used as a classifier by limiting the domain of the logistic function to positive real numbers only. Logistic regression can be used as a classifier by using a threshold on the outcome of the logistic function and using this threshold to classify the inputs. Logistic regression can be used as a classifier by expanding the range of the output of the logistic function. Logistic regression can be used as a classifier by removing the nonlinear relationship between input and output.
Logistics regression can be used as a classifier by Logistic regression can be used as a classifier. The second option is correct.

If x^2 y^3 = 10 and x^3 y^2 = 8, what is the value of x^5 y^5
Step-by-step explanation:
so,
x²y³ = 10
x³y² = 8
what is the value of x⁵y⁵ ?
don't you see right away that 2+3 and 3+2 both equal 5 ?
so, x³x² = x⁵
y²y³ = y⁵
so, I only need to multiply both equations with each other. and I get
x²y³×x³y² = 10×8
x⁵y⁵ = 80
why ? because multiplications and exponents (which are nothing else than multiplications) are all communicative :
a×b = b×a.

Assuming that all the grapes have the same probability of being randomly picked:
a) 0.11b) 0.24How to find the probabilities?
We know that there are 8 green grapes and 15 red grapes on the bowl, so there is a total of 23 grapes.
a) Here we need to find the probability that both grapes are green. Remember that the probability of getting a green grape is equal to the quotient between the number of green grapes and the total number of grapes, this is:
P = 8/23
But then he must take another, because he already took one, the number of green grapes is 7, and the total number of grapes is 22, so for the second grape the probability is:
P' = 7/22.
The joint probability is the product of the two individual probabilities:
prob = (8/23)*(7/22) = 0.11
b) For the first green grape we know that the probability is:
P = 8/23
Then he must get a red grape. There are 15 red grapes and 22 grapes in total, so the probability is:
P' = 15/22
Then the joint probability is:
prob = (8/23)*(15/22) = 0.24
