The two mathematical expressions can be written as:-
2) . [ 23 + ( 14 ÷ 2 ) - 20 ] = 5
3) . [ 9² - ( 8 x 4 ) + 26 ] = 75
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The two expressions will be solved as:-
For the first problem, the numbers are 23,2,14, and 20. The expression will be written as:-
[ 23 + ( 14 ÷ 2 ) - 20 ] = 5
[ 23 + 2- 20 ] = 5
[ 25 - 20 ] = 5
5 = 5
The numbers for the second expression are 8,26,9 and 4. The expression can be written as:-
[ 9² - ( 8 x 4 ) + 26 ] = 75
[ 81 - 32 + 26 ] = 75
[ 49 + 26 ] = 75
75 = 75

Maria started her savings account with $105. she adds $10 to it each month, including the first month. Jana Rae started her account with $0 she adds $25 to it each month. after how many months will the girls have the same amount in their accounts? how much will they have?
Answer:
After 7 months, the girls will have the same amount in their accounts. They will have 175.
Step-by-step explanation:
Maria:
Starts with $105
Adds $10 each month
Jana Rae:
Starts with $0
Adds $25 each month
Set up an equation for both Maria and Jana.
m will represent the number of months.
Maria: 105 + 10m
Jana: 0 + 25m
You can do guess and check.
Let’s say m is equal to 6.
Subsitute m with 6 for both equations and check if they both end up having the same answer.
Maria: 105 + 10(6) = 165
Jana: 0 + 25(6) = 150
Is 165 and 150 equivalent? No
Let’s try m = 7 and do that same thing.
Maria: 105 + 10(7) = 175
Jana: 0 + 25(7) = 175
Now is the answer equal? Yes
So therefore, after 7 months, the girls will have the same amount in their accounts. They will have 175.

Find the midpoint given the endpoints (4,-10) (22,-4) Please do not use space when
typing in your answer
Answer: (13,-7)
Step-by-step explanation:
By using the formula \((x_{m},y_{m}) =(\frac{x_{1}+x_{2} }{2},\frac{y_{1}+y_{2} }{2} )\)
\((x_{m},y_{m})\\\) is the coordinates of the midpoint.
For finding the midpoint X variable do:
\((\frac{4+22}{2})=13\)
For finding the midpoint Y variable do:
\(\frac{-10+(-4)}{2} = -7\) (you can either keep the parenthesis or take them out. Either way, the answer is the same.
Considering coordinate numbers follow the format: (x,y), you'll simply just substitute the numbers found above into their respective places.
x: 13
y: -7

we draw a random sample of size 36 from the normal population with variance 2.1. if the sample mean is 20.5, what is a 95% confidence interval for the population mean?
The 95% confidence interval for the population mean is approximately [20.03, 20.97].
What is confidence interval?The percentage (frequency) of acceptable confidence intervals that include the actual value of the unknown parameter is represented by the confidence level.
To calculate the 95% confidence interval for the population mean based on a sample of size 36 with a known variance of 2.1 and a sample mean of 20.5, we can use the formula for a confidence interval for a population mean:
CI = \(\bar X\) ± z * (σ / √n),
where:
CI is the confidence interval,
\(\bar X\) is the sample mean,
z is the z-score corresponding to the desired level of confidence (in this case, 95% confidence),
σ is the population standard deviation,
n is the sample size.
Since we have the population variance (2.1), we can calculate the population standard deviation as σ = √2.1 ≈ 1.45.
Now, let's calculate the confidence interval:
CI = 20.5 ± z * (1.45 / √36).
The z-score corresponding to a 95% confidence level is approximately 1.96 (you can look this up in a standard normal distribution table or use a statistical software).
Substituting the values:
CI = 20.5 ± 1.96 * (1.45 / √36).
Calculating the values within the confidence interval:
CI = 20.5 ± 1.96 * 0.2417.
CI = 20.5 ± 0.4741.
Finally, we can calculate the lower and upper bounds of the confidence interval:
Lower bound = 20.5 - 0.4741 ≈ 20.03.
Upper bound = 20.5 + 0.4741 ≈ 20.97.
Therefore, the 95% confidence interval for the population mean is approximately [20.03, 20.97].

onex expects to have an ebit of $240,000 with a standard deviation of $90,000. the distribution of operating income is approximately normal. what is the probability that onex will have an ebit below $0
The probability that Onex will have an EBIT that is below $0 is 0.38%. The correct answer is C.
The first step in solving this problem is to calculate the z-score, which is a measure of how many standard deviations a value is from the mean. In this case, the mean EBIT is $240,000, and the standard deviation is $90,000.
To find the z-score for an EBIT of $0, we subtract the mean from the value and divide by the standard deviation as follows:
z = ($0 - $240,000)/$90,000 z = -2.67This gives us a z-score of -2.67. Next, we use Table V, which is a table of standard normal distribution values, to find the probability that a value with a z-score of -2.67 will fall below 0. The probability is 0.38%, which means there is a very low chance that Onex's EBIT will be below $0.
This question should be provided with answer choices, which are:

What is an equation of the line that passes through the point (-5,-3)(−5,−3) and is parallel to the line 3x+5y=153x+5y=15?
The equation for the line x+5x+4=0 that intersects the line 3x+5y=15 and passes through the point (-5,-3).
Given that,
We have to find what is the equation for the line that intersects the line 3x+5y=15 and passes through the point (-5,-3).
The x- and y-coefficients of the parallel line can be the same. Using the specified point for x and y, you can determine the value of the new constant:
In the figure we can see.
The slope of the line is 3x+5y=15
y=(15-3x)/15
y=-1/5x+1
The slope is -1/5.
y=mx+d
-3=(-1/5)(-5)+d
-3=1+d
d=-3-1
d=-4
The equation of the line is y=(-1/5)x-4
5y=-x-4
x+5y+4=0
Therefore, The equation of the line is x+5x+4=0.

Percentage error is the difference between an actual value and its expected value per the actual value which is expressed in percentage. In the given question, the percentage error is option b. 0.0772
Percentage error is the difference between an actual value and its expected value per the actual value which is expressed in percentage.
This can be expressed as;
percentage error = \(\frac{actual value - expected value}{actual value}\) x 100%
Where the actual value is the accurate value, and the expected value is derived from the actual value.
Thus in the given question, it can be deduced that,
actual value = 625.483
expected value = 625.000
The difference between the two values = (625.483 - 625.000)
= 0.483
So that,
percentage error = \(\frac{0.483}{625.483}\) x 100%
