Answer:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Step-by-step explanation:

The following information is missing in the question:

We have to find z-score for the given score on this dental anxiety scale: 12, 6

We are given the following information in the question:

Mean, μ = 11

Standard Deviation, σ = 4

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

where x is the given score on this dental anxiety scale.

For x = 12

z_{score} = \displaystyle\frac{12-11}{4} = 0.25

For x = 6

z_{score} = \displaystyle\frac{6-11}{4} = -1.25

What is the volume of a hemisphere with a diameter of 3.7 m, rounded to the nearest
lidiya [134]

Answer:

volume of the hemisphere  ≈13.3 m³

Step-by-step explanation:

To find the volume of the hemisphere, we will follow the steps below;

volume of a hemisphere = volume of a sphere/2

                                         = \frac{4}{3}πr³  /2

                                         =\frac{2}{3}πr³

from the question given, the diameter is 3.7 m, but diameter = 2×radius

radius = diameter /2   =  3.7/2 =1.85 m

π is a constant = 3.14

volume of a hemisphere = \frac{2}{3}πr³

                                          ≈  \frac{2}{3}×3.14 ×1.85³

                                           ≈13.3 m³

Therefore, volume of the hemisphere  ≈13.3 m³

Please help!! Will mark brainliest!! <br><br><br> Match each function to its domain.
Lapatulllka [165]
<span>f(x) = sqrt(x-5) Domain: all real numbers greater or equal to 5 f(x) = 7/(x-8) Domain: all real numbers except 8 f(x) = sqrt(x) Domain: all positive real numbers and 0 f(x) = 8x Domain: all real numbers The domain of a function is the set of all numbers for which that function is valid. You have 4 functions and 4 possible domains to choose from. Let's work each one out. f(x) = sqrt(x-5) You're not allowed to take the square root of a negative number. So the domain for this function would be all values of x >= 5. That way you're taking the square root of 0 or higher. Let's see if any of your choices match that. And you have the choice "all real number greater or equal to 5" f(x) = 7/(x-8) You're not allowed to divide by 0. And the denomerator becomes 0 if x equals 8. So the domain is all real numbers except 8 which happens to be one of the choices. f(x) = sqrt(x) This is much like the 1st choice. You can't take the square root of a negative number. So the domain is all non-negative numbers. Looking at the choices, there isn't a match, but there's the choice "all positive real numbers and 0" which means the same thing. So that's the answer. f(x) = 8x I don't see anything that would make it impossible to evaluate this expression. So its' domain is all real numbers. And you have that as a choice.</span>

Answer:

D. The answer is D because meat dishes have a total 13 and pasta and soup total a total of 12. So they cannot be equal unless pasta and soup have a total of 13 or the meat dishes have a total of 12
