Solve for x. -(-2-5x) + (-2) = 18 x= -90 x=-18/5 2 = 18/5 x= 90

mart [117]

Answer:

$x=\frac{18}{5}$

Step-by-step explanation:

$-\left(-2-5x\right)+\left(-2\right)=18$

Add 2 to both sides:

$-\left(-2-5x\right)-2+2=18+2$

$-\left(-2-5x\right)=20$

Divide both sides by -1:

$\frac{-\left(-2-5x\right)}{-1}=\frac{20}{-1}$

$-2-5x=-20$

Add 2 to both sides:

$-2-5x+2=-20+2$

$-5x=-18$

Divide both sides by -5:

$\frac{-5x}{-5}=\frac{-18}{-5}$

$x=\frac{18}{5}$

What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table?

sveta [45]

Answer: A B

Group 1 0.25 0.75

Group 2 0.44 0.56

Step-by-step explanation:

Since we have given that

Number of people of A in group 1 = 15

Number of people of B in group 1 = 45

Total number of people in group 1 is given by

$15+45=60$

Relative frequency of people of A in Group 1 is given by

$\frac{15}{60}=0.25$

Relative frequency of people of B in Group 1 is given by

$\frac{45}{60}=0.75$

Similarly, Number of people of A in group 2 = 20

Number of people of B in group 2 = 25

Total number of people in group 2 is given by

$20+25=45$

Relative frequency of people of A in Group 2 is given by

$\frac{20}{45}=0.44$

Relative frequency of people of B in Group 2 is given by

$\frac{25}{45}=0.56$

Hence, A B

Group 1 0.25 0.75

Group 2 0.44 0.56
