If the assumptions for the large sample confidence interval for the population proportion are not met, what adjustments can be made?.
A confidence interval is made up of the mean of your estimate plus and minus the estimate's range. This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence.
A 95% confidence interval gives you a 5% chance of being wrong. A 90% confidence interval gives you a 10% chance of being wrong. In comparison to a 99% confidence interval, a 95% confidence interval is smaller (for example, plus or minus 4.5 percent instead of 3.5 percent).
When constructing a confidence interval for a propotion, if the condition of proportion requires 10 individuals in each category is not met, then confidence interval should be adjusted.
The number of individuals in each category is increased by 2 and sample size increases by 4.

Choose the statements that are true about a cube with side length 1 unit.
It has a volume of 6 cubic units.
It has a volume of 1 cubic unit.
It has a volume of 3 cubic units.
It is called a "one block."
It can be used to measure volume.
It is called a "unit cube."
The answer to the mentioned statement are :
first statement is WRONG
the second statement is RIGHT
The third statement is also WRONG
the fourth statement is RIGHT
fifth statement is RIGHT
sixth statement is WRONG
The side of the given cube is 1 unit.
This means that the Length= Breadth = Height = 1 unit because it is cube
This means that the volume can be described as
( side ) ³
that is 1 × 1 × 1 = 1 cubic unit
thus the first statement is WRONG
However the second statement is RIGHT
The third statement is also WRONG
since it is a cube whose volume is 1 cubic unit
thus we can say that it is one block
Thus the fourth statement is RIGHT
fifth statement is RIGHT
sixth statement is WRONG

How to calculate the value?The veterinarian recorded a cat's resting heart rate to be 120 beats over a 45-second time period. The constant will be:
= 120 / 45
= 2.67
Therefore, to find the heartbeat, we have to multiply the numbers of minutes by 2.67. This is illustrated as:
= 2.67 × 0.25 = 0.6675

======================================================
Work Shown:
As you mentioned, we'll use Pythagoras' Theorem aka Pythagorean Theorem.
[tex]a^2+b^2 = c^2\\\\(x+3)^2+(4(x+2))^2 = 25^2\\\\(x+3)^2+16(x+2)^2 = 625\\\\(x^2+6x+9)+16(x^2+4x+4) = 625\\\\x^2+6x+9+16x^2+64x+64 = 625\\\\17x^2+70x+73 = 625\\\\17x^2+70x+73-625 = 0\\\\17x^2+70x-552 = 0\\\\[/tex]
Next, we'll use the quadratic formula with a = 17, b = 70, c = -552.
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-70\pm\sqrt{(70)^2-4(17)(-552)}}{2(17)}\\\\x = \frac{-70\pm\sqrt{42436}}{34}\\\\x = \frac{-70\pm206}{34}\\\\x = \frac{-70+206}{34} \ \text{ or } \ x = \frac{-70-206}{34}\\\\x = \frac{136}{34} \ \text{ or } \ x = \frac{-276}{34}\\\\x = 4 \ \text{ or } \ x \approx -8.1176\\\\[/tex]
Ignore the negative x value solution. The sides (x+3) and 4(x+2) will be negative values if we plugged in x = -8.1176, but negative side lengths do not make sense.
This makes x = 4 the only possible solution.

If x = 4, then,

In the figure ZX = 2x + 1 YW = 3x - 1 and YX = 1, find perimeter of VYZ
The perimeter of triangle VYZ is 12 units.
How to find the perimeter of a triangle?The perimeter of a triangle is the sum of the whole sides of the triangle.
In other words, the perimeter of a triangle is the total distance covered by its boundaries or the sides.
Therefore,
perimeter of ΔVYZ = VY + ZY + ZV
Therefore,
VY = ZY = ZV = XW
Hence,
YW = YX + XW
Therefore,
XW = YW - YX
YW = 3x - 1
YX = 1
Hence,
XW = 3x - 1 - 1
XW = 3x - 2
Therefore,
perimeter of ΔVYZ = 3x - 2 + 3x - 2 + 3x - 2
perimeter of ΔVYZ = 9x - 6
ZX = YW
2x + 1 = 3x - 1
2x - 3x = - 1 - 1
-x = -2
x = 2
Therefore,
perimeter of ΔVYZ = 9(2) - 6
perimeter of ΔVYZ = 18 - 6
perimeter of ΔVYZ = 12 units

How to find angles?We have to find the variables x and y of the angles.
Therefore,
using angles in a triangle,
2x + 13 + 47 + 5y - 23 = 180
2x + 5y = 180 - 13 - 47 + 23
2x + 5y = 143
Using corresponding angles,
180 - (2x + 13) = 47 + 3x
180 - 2x - 13 = 47 + 3x
180 - 47 - 13 = 3x + 2x
120 = 5x
x = 120 / 5
x = 24
