Answer: -157,464
Step-by-step explanation:
an=a^1*r^n-1
a10=8*-3^10-1
a10=8*-3^9
a10=8*-19683
a10=-157464
Answer:
a10 = -157,464
Step-by-step explanation:
a1 = 8
a2 = -24
r = a2/a1 = -3
an = a1 × r^(n - 1)
a10 = a1 × (-3)^(10 - 1)
a10 = 8 × (-3)^(9)
a10 = -157,464

(Round your answers to 2 decimal places.)
Answer:
Mean = 31.22
Midrange = 28.50
Geometric mean = 28.74
Trimmed mean = 31.56
Step-by-step explanation:
Given the data :
39 41 25 17 48 29 31 17 24 36 17 24 40 38 42 11 43 47 27 25 17 23 43 20 32 48 26 26 9 46 44 44
Ordered data :
9, 11, 17, 17, 17, 17, 20, 23, 24, 24, 25, 25, 26, 26, 27, 29, 31, 32, 36, 38, 39, 40, 41, 42, 43, 43, 44, 44, 46, 47, 48, 48
The mean, xbar :
Xbar = Σx / n = 999 / 32 = 31.22
The midrange : (maximum - minimum) / 2
Midrange = (48 + 9) / 2 = 57 / 2 = 28.5
Geometric mean :
(x1*x2*.. xn)^1/n
Geometric mean = (x1*x2*.. xn)^1/32 = 28.74
24% trimmed mean :
24% of 32 = 0.24 * 32 = 7.68 ; this mean cutting off 8 values from the top and bottom and calculating the mean of the remaining values.
Data left :
24, 24, 25, 25, 26, 26, 27, 29, 31, 32, 36, 38, 39, 40, 41, 42
Σx / n = 505 / 16 = 31.5625
Trimmed mean = 31.56

Answer:
[tex]Area = 395.2cm^2[/tex]
Step-by-step explanation:
Given
The attached prism
Required
The surface area
This is calculated as:
[tex]Area= 2(LW + LH + WH)[/tex]
Where:
[tex]Length \to L=5.78[/tex]
[tex]Width \to W=12.7[/tex]
[tex]Height \to H=6.72[/tex]
So, we have:
[tex]Area = 2(5.78 * 12.7 + 5.78 * 6.72 + 12.7 * 6.72)[/tex]
Using a calculator, we have:
[tex]Area = 395.1832[/tex]

Given that z is a standard normal random variable, what is the value of z if the area to the right of z is .9370? a. .8264 b. – 1.53 c. 1.50 d. 1.96
Answer:
z₁(s) = - 1.53
Step-by-step explanation:
a) Value of z or z₁(s) area to the right is .9370
1 - 0.9370 = 0.063
Then if area to the left is 0.063 z₁(s) = - 1.53

Answer:
[tex] 12\frac{8}{9} [/tex] cm
Step-by-step explanation:
Perimeter of the rectangle = 2(length + width)
length = 3⅚ cm
width = [tex] 2\frac{11}{18} [/tex] cm
Thus:
Perimeter = [tex] 2(3\frac{5}{6} + 2\frac{11}{18}) [/tex]
Change the fractions to improper fractions
Perimeter = [tex] 2(\frac{23}{6} + \frac{47}{18}) [/tex]
Add
= [tex] 2(\frac{69 + 47}{18} [/tex]
= [tex] 2(\frac{116}{18} [/tex]
= [tex] \frac{116}{9} [/tex]
= [tex] 12\frac{8}{9} [/tex] cm

The measure of ∠BAC is π/3 radians and the measure of ∠CAD is π/2 radians. What is the measure of ∠BAD?
9514 1404 393
Answer:
5π/6 radians
Step-by-step explanation:
The whole is the sum of the parts.
∠BAD = ∠BAC +∠CAD
∠BAD = π/3 + π/2 = π(2/6 + 3/6)
∠BAD = 5π/6

Find the Z-scores that separate the middle 22% of the distribution from the area in the tails of the standard normal distribution.
The Z scores are _____?
Find the value of z a The value of α = 0.27
The value of z 0.27 is _____
Find the Z-score such that the area under the standard normal curve to the left is 0.33
_____ is the z - score such that the area under the curve to the left is 0.33.
Answer:
0.279
0.613
-0.44
Step-by-step explanation:
The Zscore that seperates the middle 22% of the distribution ; could be obtained thus. The midpoint is the mean and the probability to either the right or left could be obtained.
To obtain the Zscore that seperates the middle 22% is equivalent to :
The probability to the left of the distribution :
P(x < (0.5 + 0.22/2) = p(x < 0.61)
Using the Z probability calculator :
P(x < 0.61) is equivalent to a Zscore of 0.279
α = 0.27
Z(1 - α) = Z(1 - 0.27) = Z0.73 = p(Z < 0.73) = 0.613
P(x < 0.33) = - 0.44 (Z probability calculator)

3. (x, y) = (-1, -2)
4. (x, y) = (-8, 6)
Step-by-step explanation:
The equations are graphed in the attachments.
3. The equations of problem 3 are easily graphed using the slope and intercept. The second equation is ...
y = 2x
when solved for y.
__
4. The equations of problem 4 may be more easily graphed using the x- and y-intercepts. These are found by dividing the constant by the coefficients of x and y, respectively. Once the intercepts are plotted, a line can be drawn through them to make the graph of the equation.
A teenager earns $10 for every 600 square feet mowed in addition to $12 for supplies for each lawn he mows. Which function represents y, the teenager’s pay when he mows a lawn that is x square feet in size?

y = 10x + 12
y = 1/60x + 12
y = 1/60x + 1/60
Answer: b

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
The figure of hexagon is shown.
Since, We know that;
All of its interior angles must be less than 180 degrees, and all the vertices are pointed outwards is called ''Convex Hexagon''.
Here, By graph of figure;
All of its interior angles must be less than 180 degrees, and all the vertices are pointed outwards.
Hence, The correct phrase which is best describes this polygon is,
⇒ Convex Hexagon

8 (d+2) – 36 = 2 + 6(1 – d)
Answer:
d=2
Step-by-step explanation:
8(d+2)-36=2+6(1-d)
Expand the equation
8d+16-36=2+6-6d
Put like terms together
8d+6d = 2+6-16+36
14d= 28
Divide 14 on both sides to get the value of d
