5 1/3 + x = 2 1/2. Use least common denominator or easiest common denominator. Please work out

julia-pushkina [17]

Answer:

The answer is x = -17/6.

Step-by-step explanation:

Given:

5 1/3 + x = 2 1/2 . Using least common denominator.

Now, to solve the equation:

$5\frac{1}{3}+x=2\frac{1}{2}$

$=\frac{16}{3} +x=\frac{5}{2}$

Subtracting both sides from 16/3 we get:

$x=\frac{5}{2}- \frac{16}{3}$

Now, the least common denominator of 2 and 3 is 6.

So, we using this we calculate:

$x=\frac{5\times 3-16\times 2}{6}$

$x=\frac{15-32}{6}$

$x=\frac{-17}{6}$

Therefore, the answer is x = -17/6.

Answer:

A. W

Step-by-step explanation:

Because this is a rigid transformation, quadrilaterals WXYZ and ABCD are congruent. Corresponding parts of corresponding figures are congruent, so W is congruent to A and because we know the measure of angle A, you also know the angle measure of W.

The heights of men in the United States are approximately normally distributed with mean 69.1 inches and standard deviation 2.9

Gre4nikov [31]

Answer:

Step-by-step explanation:

Let M be the heights of men in the United States and W be the heights of women in the United States

Given that M is N(69.1, 2.9) and W (63.7, 2.7)

For a husband and wife we have average height as

$\frac{x+y}{2}$ =Z (say)

$Mean =E(z) = \frac{1}{2} [E(M)+E(W)] = 66.4 inches$

Var (Z) = $Var (\frac{x+y}{2} )=\frac{1}{4}[Var(x)+ Var(y)+2 cov (x,y)]\\$

= $0.25[2.9^2+2.7^2+2*r*sx*sy]\\= 0.25(20.398)\\=5.0995$

Mean = 66.4" and std dev = 2.258
