26 = 5 (x + 10) + 3x
26 = 5x + 50 + 15x
26 = 5x +15x + 50
26 = 20x + 50
26 - 50 = 20x - 50
-14 = 20x
-14 / 20 = x
-0.7 = x
Answer:
Step-by-step explanation:
tax = 1/20 of price
1/20 of $3 = 1/20 × 3 = 3/20 = $0.15
1/20 of $800 = 1/20 × 800 = $40
Answer:
-0.67
Step-by-step explanation:
Given that :
Population mean, μ = 4.7
Sample size, n = 68
Sample mean, M = 4.3
Sample standard deviation, s = 0.6
The effect size, d can be obtained using the relation :
d = (M - μ) / s
d = (4.3 - 4.7) / 0.6
d = - 0.4 / 0.6
d = - 0.66666
d = - 0.67
Hence, effect size associated with a single-sample t test is - 0.67
Th area of a right triangle is A = 1/2 (ab), where a and b are the legs of the right angle. So area of the base is, A = 1/2 (9 x 12) = 108 cm2. With 2 bases, total area of base is 108 times 2, which is equal to 216 cm2. The other side of the triangular base nypotenuse) can be computed by Phythagorean theorem. Hypotenuse = square root of sum of the suare of 9 and 12. This is equal to 15 cm. There are other 3 rectangular faces with the following dimensions: 9 by 10 cm, 12 by 10 cm and 15 by 10 cm. Area of the other faces are 90, 120 and 150 cm2, by multiplying the length and width, only. Total area is 576 cm2.
