What is Number system?A number system is defined as a system of writing to express numbers.
We have to find the operations which make the value to be true.
The given numbers are 5, 23, 18, 8, and 4.
Let us use the operation addition, subtraction and addition.
Use the subtraction between twenty three and eight.
Use subtraction between eight and four.
5 x (23-18) x (8-4)=100
Hence, 5 x (23-18) x (8-4)=100 is the Order of Operations which make it true

find the gretest number which devded by 181 and 236 leave a remainder of 5 in each case
Answer:
The greatest number is 11
Step-by-step explanation:
Given
Dividends: 181 and 236
Remainder: 5
Required
Determine a divisor that satisfies the above condition
Let the required divisor be represented with x.
Since a remainder of 5 is expected, then x can divide (181 - 5) and (236 - 5) without remainders.
So, we have:
[tex]181 - 5 = 176[/tex]
[tex]236 - 5 = 231[/tex]
Next, we calculate the GCF of 176 and 231
[tex]176 = 2 * 2 * 2 * 2 * 11[/tex]
[tex]231 = 3 * 7 * 11[/tex]
The greatest common factor, GCT is:
[tex]GCF = 11[/tex]
Hence, the required divisor is 11
Solve the problem.
A dress regularly sells for $135. The sale price is $93. Find the percent decrease of the sale price from the regular
price.
31.1%
221.4%
45.2%
68.9%
Answer:
32% Decrease
Step-by-step explanation:
93 = x * 135 (divide both sides by 135 to get X alone.)
x=0.68 - Repeated (This tells us that it was paid 68% of the OG price.)
1 - 0.68 = 0.32 (We need to subtract the percent paid from the OG price to find the percent discount.)
The percent decrease was 32% off.

Many ancient tombs were cut from limestone rock that contained uranium. Since most such tombs are not well-ventilated, they may contain radon gas. In one study, the radon levels in a sample of 12 tombs in a particular region were measured in becquerels per cubic meter (Bq/m3). For this data, assume that x(over-bar)= 3,469 Bq/m3 and s= 1,135 Bq/m3. Use this information to estimate, with 95% confidence, the mean level of radon exposure in tombs in the region. Interpret the resulting interval.
Answer:
95% confidence interval of the mean level of random exposure in tombs in the region.
(2746.868 , 4191.132)
Step-by-step explanation:
Step(i):-
Given sample size 'n'= 12
Mean of the sample x⁻ = 3,469
and standard deviation of the sample 's' = 1,135
95% confidence intervals are determined by
[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} +t_{0.05} \frac{S}{\sqrt{n} } )[/tex]
Degrees of freedom = n-1 = 12-1= 11
Step(ii):-
95% confidence intervals are determined by
[tex](3469- 2.201 \frac{1135}{\sqrt{12} } , 3469+2.201\frac{1135}{\sqrt{12} } )[/tex]
( 3469-722.132 , 3469 +722.132)

In a large city, 82% of residents own a cell phone. Suppose that we randomly select three city residents. What is the probability that at least one of the three residents does not own a cell phone
Answer:
P(X≥1) = 0.45 (approximately)
Step-by-step explanation:
Let X be a random variable, then X follows a binomial distribution with probability of success, p and number trials, n.
The probability distribution is given as:
P(X) = nCx * p^x * (1 – p)^(n – x)
Where p is Probability of success, n is number of trials and x is total number of successes.
Probability of having phone is 82% = 0.82
Probability of not having phone is 100% – 82% = 0.18.
Since the trials are interested in those that are not having phone, then probability of success, p = 0.18.
Number of trials, n = 3.
P(X ≥ 1) = 1 – P(X < 1) = 1 – P(X = 0)
P(X = 0) = 3C0 * (0.18)^0 * (0.82)^(3) = 1 * 1 * 0.551368 = 0.551368
P(X ≥ 1) = 1 – 0.551368 = 0.448632 ≈ 0.45
