Answer: 
<u>Step-by-step explanation:</u>
Use the Slope formula: 
and the Point-Slope formula: y - y₁ = m(x - x₁)
a) (-2, 0) and (3, 4)
Let (x₁, y₁) = (-2, 0)
y - y₁ = m(x - x₁)
b) m = 1/3 (x₁, y₁) = (2, 4)
y - y₁ = m(x - x₁)
Answer: trapezoid
Step-by-step explanation: A <u>trapezoid</u> is a quadrilateral
with exactly one pair of parallel sides.
Also, quadrilaterals are two-dimensional shapes.
So it's impossible that's its 3-d.
Answer:
The probability of finding a sample mean less than 18 hours is 0.0082
Step-by-step explanation:
To find the probability of finding a sample mean less than 18 hours, we need to calculate the z-score of this sample mean 18. And the probability of finding a sample mean less than 18 hours is P(z<z(18)).
Z-score can be calculated as follows:
z(18)=
where
- X is the sample mean (18 hours)
- M is the average hours dentists spend per week on fillings (20 hours)
- s is the standard deviation (10 hours)
- N is the sample size (144)
Putting the numbers, we get:
z(18)=
Using z- table we can find that P(z<z(18)) = 0.0082
Answer:
37.5 g
Step-by-step explanation:
The final solution will contain 3% × 100 g = 3 g of solute. This amount of solute will be found in w grams of 8% solution, where ...
... 3 = 0.08 × w
... 3/0.08 = w = 37.5 . . . . . grams of 8% solution
