Answer:
x> 1
Step-by-step explanation:
X-7>-6
Add 7 to each side
X-7+7>-6+7
x> 1
All 6 members of a family work. Their hourly wages (in dollars) are the following.
18, 14, 35, 34, 11, 26
Assuming that these wages constitute an entire population, find the standard deviation of the population. Round your answer to two decimal places.
Answer:
66 cm³
Step-by-step explanation:
From the diagram,
Volume of the prism(v) = Area of the base (A)×Height(h)
v = A×h............... Equation 1
But,
A = bh/2.................... Equation 2
Where b = base of the triangle, h = height of the triangular base.
Substitute equation 2 into equation 1
v = (bh/2)H.................... Equation 3
Also for the diagram,
Given; b = 3 cm, h = 4 cm, H = 11 cm
Substitute these values into equation 3
v = (3×4×11)/2
v = 132/2
v = 66 cm³
Answer:
The statement is not true. There is an error in the following step:
Step-by-step explanation:
Here is the complete proof:
(because k + k - (k - 1) = k + 1)
(By laws of exponent)
(Since the power of r is a negative integer i.e. -1 it will shift to the numerator)
(We get this equation after canceling out the similar terms in numerator and denominator in previous step)
(Provided r > 1 or r < -1)
Answer:
140°
Step-by-step explanation:
Since we know that a circle is 360 degrees, and we are given three angles, we can subtract what we know from 360 to get ∠PTQ:
360 = 120 + 60 + 40 + ∠PTQ
360 = 220 + ∠PTQ
<u>-220 -220</u>
140 = ∠PTQ
∠PTQ = 140°
