Answer:

1. x - 5 = 20

2. x + 2y = -6

3. 5x² = 12

Step-by-step explanation:

1. 5 less than x is 20

x - 5 = 20

2. the sum of x and twice y equals -6

x + 2y = -6

3. the product of 5 and x squared results in 12

5x² = 12

HELP ON THE GRAPH ONE

velikii [3]

The answer is B because you have a positive slope (m in y = mx + b) so that eliminates C and D. And you have a positive y-intercept (b in y = mx + b). This eliminates option A as well, which leaves you with option B.

Suppose a normal distribution has a mean of 266 and a standard deviation of

Jet001 [13]

Answer:

P(x>278) is 0.16

Step-by-step explanation:

We are given that a normal distribution has a mean of 266 and a standard deviation of 12.

Mean = $\mu =266$

Standard deviation = $\sigma = 12$

We are supposed to find P(x > 278)

So, Formula : $Z=\frac{x-\mu}{\sigma}$

$Z=\frac{278-266}{12}$

Z=1

Refer the z table for p value

p value = 0.8413

P(x<278) is 0.84

P(x>278)=1-P(x<278)=1-0.84=0.16

Option A is true

Hence P(x>278) is 0.16
