Answer:
A) it depends. If they bought 10 calculators, we would multiply 31.25 by 10. 31.25x10=$312.50
B)Divide 500 by 31.25. Since each calculator is $31.25, we divide $500 by it to see how many they can buy with $500. 500/31.25=16

Answers
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]
[tex]Area = 395.2cm^2[/tex] ---- approximated
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.
Answers
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)

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
Thus, The correct phrase which is best describes this polygon is,

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]

y = 2x
when solved for y.

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

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.
