Answer:
x ∈ {2.07014981016}
Step-by-step explanation:
The equation can be rewritten as ...
√x = 18-8x
x = 324 -288x +64x²
64x² -289x +324 = 0
x = (289 ±√577)/128 ≈ {2.07015, 2.44548}
Since √x must be positive, we know that ...
18 -8x ≥ 0
x ≤ 18/8 = 2.25
The larger of the above solutions is extraneous, so the solution set is ...
x ∈ {(289 -√577)/128} ≈ {2.07015}
Answer:
d. All of the above
Step-by-step explanation:
a. Statistics provides the tool to measure the central tendency of a given data. One of such measure is the statistical mean popularly referred to as the mean.
b. The correlation between variables can be determined by the use of statistical tools. correlation is the degree to linearity between variables,
c. Experts in different fields from Accounting to Zoology make use of statistics in their analysis.
From the above analysis, it can be safely concluded that all of the above (i.e. option d.) is correct.
The force needed to keep the cart at rest is 149.022 pounds
<h3>Force and Motion</h3>
Given Data
- Weight of cart = 200 pounds
The force needed to keep the cart at rest is the vertical component of the resultant force, hence we have
Fy = Mg sin θ
Substituting our given data we have
Fy = 200 sin 40
Fy = 200 *0.74511
Fy = 149.022 pounds

Step-by-step explanation:
Answer:
c) 6× (9+8) = (6 × 9) + (6× 8)
Step-by-step explanation:
<u><em>Distributive property of multiplication</em></u>
The distributive property of multiplication
a(b+c) = a b + a c
(a+b)c = ac + bc
6× (9+8) = (6× 9) + (6×8)
