Answer:
77.44%
49.87%
Step-by-step explanation:
If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air
on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056
Air left on the second day = 88% - 10.56% = 77.44%
After a week = (100 - 12%)^7 = 49.87%

Penn State extension is interested in comparing the body length southern grass cicadas and citrus cicadas. The extension collected a random sample of 20 southern grass cicadas and found that they have a mean body length of 16.22 millimeters and a standard deviation of 1.34 millimeters. A separate random sample of 20 citrus cicadas resulted in a mean body length of 13.41 millimeters and a standard deviation of .73 millimeters. What is the standard error of the difference parentheses southern grass minus citrus) between the sample means
Answer:
The standard error between the sample mean is approximately 0.3412
Step-by-step explanation:
The equation for the standard error of a difference in sample mean of equal sample sizes is given as follows;
[tex]SE(\overline x_1 - \overline x_2)={\sqrt{\dfrac{s_{1}^{2} }{n_{1}}+\dfrac{s _{2}^{2}}{n_{2}}}}[/tex]
The given parameters are;
The number of sample of southern grass cicadas, n₁ = 20
The mean body length of the southern grass cicadas, [tex]\overline x _1[/tex] = 16.22 mm
The standard deviation, s₁ = 1.34 mm
The number of sample of citrus cicadas, n₂ = 20
The mean body length of the citrus cicadas, [tex]\overline x _2[/tex] = 13.41 mm
The standard deviation, s₂ = 0.73 mm
[tex]SE(16.22 - 13.41)={\sqrt{\dfrac{1.34^{2} }{20}+\dfrac{0.73^{2}}{20}}} \approx 0.3412[/tex]
The standard error between the sample mean, SE ≈ 0.3412

Marion bought 14 packages of plastic frog and lizard fishing lures. She bought frog lures in
packages of 4 and lizard lures in packages of 6 for a total of 72 lures. How many of each lure did
Marion buy?
A. 6 lizards and 4 frogs
B. 4 lizards and 8 frogs
C. 48 lizards and 24 frogs
D. 24 lizards and 48 frogs
Answer:
C. 48 lizards and 24 frogs
Step-by-step explanation:
Let F = number of frog lures, and let L = number of lizard lures.
Marion bought 14 packages of plastic frog and lizard fishing lures.
She bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures.
F + L = 72
F/4 + L/6 = 14
12 * F/4 + 12 * L/6 = 12 * 14
3F + 2L = 168
(+) -3F - 3L = -216
------------------------------
-L = -48
L = 48
F + L = 72
F + 48 = 72
F = 24
Answer: C. 48 lizards and 24 frogs

The rectangle below has an area of 70 square meters. Find the dimensions of the rectangle. (x - 11) (x - 8)
Answer:
the dimensions of the rectangle are 10 and 7.
Step-by-step explanation:
Given;
area of the rectangle, A = 70 m²
dimensions of the rectangle, = x - 11 and x - 8
The area of rectangle is calculated as;
A = L x B
70 = (x - 11)(x - 8)
70 = x² - 8x - 11x + 88
0 = x² - 8x - 11x + 88 - 70
0 = x² - 19x + 18
0 = x² - x - 18x + 18
0 = x(x - 1) -18(x - 1)
0 = (x - 18)(x - 1)
0 = x - 18 or
0 = x - 1
x = 18 or 1
The dimensions of the rectangle are calculated as;
L = 18 - 11 = 7
B = 18 - 8 = 10
Therefore, the dimensions of the rectangle are 10 and 7.
the plane of a room is shown in the picture. the scale is 2 inches: 6 feet. what is the actual length of the room?
what is the actual width of the room? what is the actual area of the room?
Since 2 inches = 6 ft and length of room in the place = 7 inches,
(2x3.5) inches = 6x3.5 ft
7 inches = 21ft
Actual Length of Room = 21 ft.
Width of Room in plane = 3 inches
(2x1.5) inches = 6 x 1.5 ft
= 9 ft
Actual Length of Rook = 9 ft.
Actual Area of Room = Actual Length of Room x Actual Width of Room = 21 x 9 = 189 ft^2

can somebody please solve for x and y, if you get the answers correct I'll give you extra points
Answer:
1) x = 18 2) x = 7
Step-by-step explanation:
Edit: Decided to solve the second too! :)
1)
12/16 = x/(x+6)
12x + 72 = 16x
72 = 4x
x = 18
2)
(-4 + 4x)/64 = 27/72
-288 + 288x = 1,728
288x = 2,016
x = 7

The cross-sections of the solids are sectors. Find the surface area, rounding your answer to 1 decimal place.
Answer:
The total surface area of the figure is approximately 10.2 m²
Step-by-step explanation:
The dimensions of the solid are;
The shape of the solid = An half cylinder
The diameter of the cylinder, D = 1.6 m
The length of the cylinder, l = 2 m
The surface area of the curved part of the solid = π × D × l ÷ 2
Therefore;
The surface area of the curved part of the solid = π × (1.6 m) × 2 m/2 ≈ 5.03 m²
The area of the curved surface, V = 5.03 m²
The area of the rectangular top, A = 1.6 m × 2 m = 3.2 m²
The area surface of the semi-circular sides of the figure = 2 × π·D²/4 ÷ 2
Therefore;
The area surface of the semi-circular sides of the figure = 2 ×π × (1.6 m)²/4 ÷ 2 ≈ 2.01 m²
The total surface area of the figure, A = 5.03 m² + 3.2 m² + 2.01 m² = 10.24 m²
The total surface area of the figure ≈ 10.2 m² (rounding to 1 decimal place)

The equation of a circle is x^2 + y^2 = 56.25
Answer:
Step-by-step explanation:
General equation of circle with center at (0, 0) : x² + y² = r²
x² + y² = 56.25
x² + y² = 7.5²
Radius = 7.5 units
Center (0 , 0)
A comapny's stock was selling 16$ a share. A month later it was selling at 20$ a share. What is the percentage gain?
Answer: 25%
Step-by-step explanation:
Given
Initial Cost of share [tex]C.P.=16\$[/tex]
After a month, its selling price is [tex]S.P.=20\$\ \text{per share}[/tex]
The gain percentage is given by
[tex]\Rightarrow \text{Gain }\ \%=\dfrac{\text{S.P.-C.P.}}{\text{C.P.}}\times 100[/tex]
[tex]\Rightarrow \text{Gain}\ \%=\dfrac{20-16}{16}\times 100=25\%[/tex]
Write the series using summation notation: -1 +4-9+ 16 - 25+ ...
