Answer:
0.0238 g
Step-by-step explanation:
Given that:
the certain mineral = potassium and a medium artichoke contain about 0.17 g of it.
Suppose a medium artichoke contains about 14% of the recommended amount of a certain mineral.
On Average, the amount an adult should have each day = 0.17 g × (14/100)
= 0.0238 g
Answer:

and x=4
Step-by-step explanation:
We are given that a curve

We have to find the equation of tangent at point (4,2) on the given curve.
Let y=f(x)
Differentiate w.r.t x

By using the formula 
Substitute x=4
Slope of tangent

In given question


By comparing we get a=4
Point-slope form

Using the formula
The equation of tangent at point (4,2)




Answer:
Usual, because the result is between the minimum and maximum usual values.
Step-by-step explanation:
To identify if the value is usual or unusual we're going to use the Range rule of thumbs which states that most values should lie within 2 standard deviations of the mean. If the value lies outside those limits, we can tell that it's an unusual value.
Therefore:
Maximum usual value: μ + 2σ
Minimum usual value: μ - 2σ
In this case:
μ = 153.1
σ = 18.2
Therefore:
Maximum usual value: 189.5
Minimum usual value: 116.7
Therefore, the value of 187 lies within the limits. Therefore, the correct option is D. Usual, because the result is between the minimum and maximum usual values.
