Answer:
(c) Below par
Step-by-step explanation:
Ratio at which stock is bought = 211/2
= 105.5
Therefore, the par value = 105.5
Recent ratio of stock = 203/8
= 25.375
Value of stock today = 25.375
Since the ratio is decreased Hence, the value of stock is below par value.
x^2+6x+4= -2x+4
Answer:
0,-8
Answer explanation:
x^2+6x+4=-2x+4
or, x^2+6x+4+2x-4=0
or, x^2+8x=0
Therefore, x(x+8)=0
Either,
x=0
or,
x+8=0
x=-8
hence,x=0, -8
To use a z-procedure to construct a confidence interval for a population proportion, the following conditions must be met:
D) The sample must be random and sufficiently large.
This means that the sample should be selected in a way that each individual has an equal chance of being included. Additionally, the sample size should be sufficiently large to ensure that the normal approximation for the sampling distribution of the sample proportion is valid.
It's important to have a random sample because it helps to ensure that the sample is representative of the population, making the results more reliable and generalizable.
As for the sample size, it should be large enough to satisfy the condition of having at least 10 successes and 10 failures. This ensures that the normal approximation can be applied.
The other answer choices, A) The sample size must be small, B) The population standard deviation must be known, and C) The population must be normally distributed, are incorrect and do not apply to the conditions for using a z-procedure to construct a confidence interval for a population proportion.
By meeting the conditions of having a random and sufficiently large sample, you can use a z-procedure to construct a confidence interval for a population proportion.Answer:

Answer with explanation:
Commutative property under subtraction:
If a and b are any two real numbers such that,⇒ a-b =b-a, then we say that ,a and b Satisfy Commutative property under Subtraction.
Take any two real numbers
a=5.6
And,b=7
→a-b
=5.6-7
= -1.4
→b-a
=7-5.6
=1.4
So,a-b≠b-a
Therefore , we can say that, real numbers doesn't satisfy commutative property under subtraction.
Option D: ⇒5-1≠1-5
This statement shows that, commutative property doesn't work under subtraction.
The 108 square root value to the nearest tenth is approximately 10.4
The square root of a number represents a value that, when multiplied by itself, results in the original number. In this case, we're looking for the square root of 108. We can use various methods such as long division, approximation techniques, or calculators to find this value.
When we calculate the square root of 108, we get a value of approximately 10.392304845413264.
However, since we are asked to round to the nearest tenth, the value becomes 10.4.
This means that when you square 10.4 (10.4 * 10.4), you get approximately 108.16, which is close to the original value of 108.

Answer:
the square root would be 10.4
Answer:
23/8
Step-by-step explanation:
Slope = Rise / Run
Rise = -10 - 13 = -23
Run = -15 - (-7) = -8
Slope = -23 / -8 = 23/8
