Answer:
0.8770
Step-by-step explanation:
We are dealing with a mean of a sample, so we use the formula

Our mean, μ, is 174.9 and our standard deviation, σ, is 35.2. Our sample size, n, is 35. To find P(X > 168),
z = (168-174.9)/(35.2÷√35) = -6.9/(35.2÷5.9161) = -6.9/5.9499 = -1.16
Using a z table, we see that the area under the curve to the left of this value is 0.1230. However, we want the area to the right; this means we subtract from 1:
1-0.1230 = 0.8770
According to the given information, we build the equation for the cost. After we build the equation, the equation that relates these measures is:

Cost:
0.3 kilograms of tomatoes, at 3.30 dollars per kilogram.
Thus, the cost starts at:

y kilograms of cucumbers, at x dollars per kilogram.
Considering this, the cost will now be of:

0.2 kilograms of carrots, at z dollars per kilogram:
Now, we have to consider this for the cost, so:

Answer:
Step-by-step explanation:
There are a couple of relations that are applicable to these questions.
- the product of segment lengths of crossed chords is the same for both chords
- the angle formed at crossed chords is the average of the intercepted arc measures
__
The segment lengths relation tells us ...
10x = 8×7 . . . . . . products of segment lengths are equal
x = 56/10 = 5.6 . . . . divide by 10
__
The value of y° is the average of the intercepted arcs:
y° = (85° +45°)/2 = 65°
_____
<em>Additional comment</em>
This diagram does not have enough information to allow computation of z. We would need to know the intercepted arc, or the length of the secant that meets tangent z.
