Answer:

x = $\frac{22}{3}$

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = - 6 when x = 2, then

- 6 = 2k ( divide both sides by 2 )

- 3 = k

y = - 3x ← equation of variation

When y = - 22, then

- 22 = - 3x ( divide both sides by - 3 )

x = $\frac{-22}{-3}$ = $\frac{22}{3}$

In California in 2000, the ballot included an initiative to add "none of the above" to the list of options in all candidate race

sveticcg [70]

Answer:

No, because the sample was randomly selected.

Step-by-step explanation:

In this example, the main element that we need to focus on is the way in which the sample was determined. We learn that the sample was taken in California with 1000 people. However, this sample was random, and the survey was conducted in both English and Spanish. The fact that this was a random sample means that it is representative of the population. The size of the population does not affect the accuracy of a random sample.

Let x be normally distributed with mean μ = 133 and standard deviation σ = 23. use table 1.

A) z value = (x - π) / <span>σ = 100 - 133 / 23 = -1.43
p(<= 100) = 0.0764

If < A and < B form a linear pair, and < A = x - 13 degrees, and < B = x + 7 degrees, then find x. Select one: a. 12

Andreas93 [3]

The correct value of "x" will be "93".

According to the question,

A linear pair of sum to 180°,

then

→ $x-13+x+7=180$

→ $2x -6=180$

By adding "6" both sides of the equation, we get

→ $2x-6+6=180-6$

→ $2x=186$

→ $x = \frac{186}{2}$

→ $x = 93$

Thus "option d" is the right answer.
