Answer:

Z score is a statistical that corresponds to the standarization of the regular score to a normal dsitribution

The formula for Z score is Z = [X - mean ]./ (standar deviation)

Here X = 930.00; mean = 900.00; and standard deviation = 15.00

Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00

Answer: 2.00

This circle is centered at the origin, and the length of its radius iS 6. What is
VikaD [51]

\sf{\qquad\qquad\huge\underline{{\sf Answer}}}

The equation of circle in standard form can be represented as :

\qquad \sf  \dashrightarrow \:(x - h) {}^{2}  + (y - k) {}^{2}  = r {}^{2}

where,

  • h = x - coordinate of centre = 0

  • k = y - coordinate of centre = 0

  • r = radius of circle = 6 units

now, let's plug in the values :

\qquad \sf  \dashrightarrow \:(x - 0) {}^{2}  + (y - 0) {}^{2}  = 6 {}^{2}

\qquad \sf  \dashrightarrow \: {x}^{2}  +  {y}^{2}  = 36

That's the required equation of circle.

Whole-wheat bread costs $2.06/lb. How much would 3.8 lb of whole-wheat bread cost?
Xelga [282]
Whole-wheat bread = $2.06/lb

We need the cost of 3.8 lbs of whole-wheat bread.

So, we simply need to multiply the cost with the amount needed.

(cost per pound) × (amount of bread)

($2.06) × (3.8)

Simplify.

$7.828

Round to the nearest tenths.

$7.83

So, 3.8 pounds of whole wheat bread costs $7.83
