For the given statement about hundredth digit of the given decimal z the following statement is true:
Option E. statement (1) and (2) together are not sufficient.
As given in the question,
Let us consider decimal z is represented by k.lmn
Here hundredth digit of z is equal to m
Now,
(1) The tenths digit of 100z is 2.
100z
= 100(k.lmn)
=klm.n
This implies n = 2
(2) The units digit of 1,000z is 2.
1,000z
= 1,000(k.lmn)
= klmn
This implies n =2
From both the statements we are getting the value of n which is not sufficient to get the value of required 'm'.
Therefore, Option E is the correct answer which shows both the statements are not sufficient to get the value required hundredth digit of decimal z.
The complete question is:
What is the hundredths digit of the decimal z ? (1) the tenths digit of 100z is 2. (2) the units digit of 1,000z is 2.

A company's minimum cost of $1000 occurs when operating for 16 hours per day. The cost of operating 8 hours per day would be $2600. Write a quadratic equation that models the company's costs.
The quadratic equation that models the company's costs is y = 25(x - 16)² + 1000
How to determine the quadratic equation that models the company's costs.From the question, we have the following parameters that can be used in our computation:
Minimum cost of $1000 at 16 hours
Operating cost of $2600 at 8 hours
A quadratic equation is represented as
y = a(x - h)² + k
The minimum point is the vertex
So, we have
(h, k) = (16, 1000)
Substitute (h, k) = (16, 1000) in y = a(x - h)² + k
y = a(x - 16)² + 1000
The cost of $2600 at 8 hours means
(x, y) = (8, 2600)
So, we have
2600 = a(8 - 16)² + 1000
Evaluate the difference
1600 = a(8 - 16)²
So, we have
64a = 1600
Divide by 64
a = 25
Substitute a = 25 in y = a(x - 16)² + 1000
y = 25(x - 16)² + 1000
Hence, the equation is y = 25(x - 16)² + 1000

A fair spinner has 12 equal sections: 3 red, 5 blue and 4 green.
It is spun twice.
What is the probability of getting not green then green?
Answer:
2/9 = approximately 0.22.
Step-by-step explanation:
There are a total of 12 possible outcomes when the spinner is spun once, so the probability of getting a result that is not green is 8/12, or 2/3. Similarly, the probability of getting green on the second spin is 4/12, or 1/3.
To find the probability of getting a result that is not green on the first spin and green on the second spin, you can multiply the probabilities of each individual event. Therefore, the probability of getting not green then green is (2/3) * (1/3) = 2/9 = approximately 0.22.
Alternatively, you could also use the principle of complementary probabilities to calculate the probability of getting not green on the first spin and green on the second spin. The probability of getting not green on the first spin is 1 - (4/12) = 8/12 = 2/3, and the probability of getting green on the second spin is still 4/12 = 1/3. Multiplying these probabilities gives a result of (2/3) * (1/3) = 2/9 = approximately 0.22.

the weight of written reports produced in a certain department has a normal distribution with mean 60 grams and standard deviation 12 grams. what is the probability that the next report will weigh less than 45 grams?
The probability that the next report will weigh less than 45 grams = 0.106
In this question, we have been given the weight of written reports produced in a certain department has a normal distribution with mean 60 grams and standard deviation 12 grams.
We need to find the probability that the next report will weigh less than 45 grams.
We have mean= 60 grams
Standard Deviation = 12 grams
First we convert 45 to z score.
45 converted to z score for given mean and standard deviation will be:
z = (45 - 60)/12
z = -1.25
So, from standard normal table a P-value:
P(x<45) = 0.10565
Therefore, the probability would be 0.10565

equation 10.25x + 680 = 12.5x +410?
The earnings for both Cynthia and Javier are same for x hours.
What is commission?
When an employee completes a task, typically selling a certain volume of goods or services, they are compensated financially. Sales commissions are occasionally used by employers as incentives to boost employee productivity. It is possible to receive a commission in place of or in addition to a salary.
Given:
Cynthia earns $680 in commissions and is paid $10.25 per hour.
Javier earns $410 in commissions and is paid $12.50 per hour.
So, the equation is
10.25x + 680 = 12.5x + 410
To simplify this equation for x.
10.25x+ 680 =12.5x +410
680 ‐ 410 = 12.5x ‐ 10.25x
270 = 2.25x
x = 270/2.25
x = 120
If we plug x = 120 in both the values 10.25x + 680 and 12.5x + 410 then we will get the same values.
Hence, the earnings for both Cynthia and Javier are same for x hours.
