Answer:
21/100
Step-by-step explanation:
there are 100 total people and 21 who have a dog but do not take walks. You can leave it like that because it cannot be simplified more.
Solve for x and y 100 points
The solution to the system of equations is x = 16/5 and y = 11/5.
What are the four equation systems?Graphing, substitution, elimination, and matrices are the four methods for solving systems of equations.
Using the substitution method, we can find x and y.
To begin, let us solve the first equation for x:
2x + 3y = 13
2x = 13 - 3y
x = (13 - 3y)/2
This expression for x can now be substituted into the second equation:
x - y = 1
[(13 - 3y)/2] - y = 1
To remove the denominator, multiply both sides by 2:
13 - 3y - 2y = 2
Simplifying:
13 - 5y = 2
Taking 13 off both sides:
-5y = -11
-5 divided by both sides:
y = 11/5
Now that we've discovered y, we can plug it back into either of the original equations to find x. Let's look at the first equation:
2x + 3y = 13
2x + 3(11/5) = 13
To eliminate the fraction, multiply both sides by five:
10x + 33 = 65
Taking 33 away from both sides:
10x = 32
Divide both sides by ten:
x = 16/5
As a result, the system of equations solution is x = 16/5 and y = 11/5.

"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John. How old am I?"
If J represents John's age, then which of the following equations could be used to solve the problem?
J + 15 = 3J - 1
3(J + 15) = J - 1
J + 15 = 3(J - 1)
J + 15 = 3(J - 1)

consider the following statement: newexample = (50 <= 75) ? 50-75 : 75-50; what is the value of the variable newexample?
the value of the variable newexample is -25.The given statement is a conditional (ternary) operator expression in the form:
condition ? expression1 : expression2
If the condition (50 <= 75) is true, then the value of newexample will be expression1 (50-75). If the condition is false, then the value of newexample will be expression2 (75-50).
Since 50 is indeed less than or equal to 75, the condition is true. Therefore, the value of newexample will be the result of expression1, which is 50-75.
Performing the subtraction, we get:
newexample = 50 - 75 = -25
Hence, the value of the variable newexample is -25.

Janet has a gross income of $20,498, adjustments to income
of $458. She has a single exemption of $8,200, and she has
deductions of $2,128. What is her taxable income?
Answer:
Here taxable income is $9,712
Step-by-step explanation:
Here, we want to calculate the value of the taxable income
To get this, we simply deduct all the deductions from the gross income
Mathematically, we have that as:
20498-(8200 + 458 + 2128) = $9,712

a function commonly used in communications textbooks for the tail probabilities of gaussian random variables is thecomplementary error function, defined as
The complementary error function is a function commonly used in communications and signal processing to compute the tail probabilities of Gaussian random variables. It is defined as:
Q(x) = 1/√(2π) ∫x to ∞ e^(-t^2/2) dt
where x is a real number. Geometrically, Q(x) represents the area under the standard normal probability density function to the right of x. This means that Q(x) gives the probability that a standard normal random variable takes on a value greater than x.
The complementary error function is related to the error function, erf(x), which is defined as:
erf(x) = 2/√(π) ∫0 to x e^(-t^2) dt
In fact, Q(x) can be expressed in terms of erf(x):
Q(x) = 1/2 erfc(x/√2)
where erfc(x) is the complementary error function.

3. A local baker orders 260 pounds of wheat flour, 120 pounds of barley flour and 90 pounds of almond flour each week for baking different types of breads. On the first day of the week, the baker uses 20% of al his almond flour. How many pounds of almond flour the baker has left?"
We will determine the remaining almond flour as follows:
*First: We determine how much does 20% of it is:
\(x=\frac{90\cdot20}{100}\Rightarrow x=18\)So, 20% of almond flour is 18 pounds. Now, we subtract this amount from the total amount:
\(r=90-18\Rightarrow r=72\)So, there are 72 pounds of almond flour left.
Margo bought the following lengths of ribbon: 3/4 yd, 1/3 yd, 1/2 yrd. How much ribbon did she buy?
Answer:
she bought 19/12 lengths of ribbon or aka 1 7/12
Step-by-step explanation:
3/4 + 1/3 + 1/2 = 13/12 + 1/2
13/12 +1/2 = 19/12
19/12 simplify is 1 7/12
Margo bought \(1\frac{2}{3}\) yards of ribbon.
What is a fraction ?A fraction represents how much part of total quantity is present.Fractions are of two types proper fraction and improper fraction.
According to the question given Margo bought some ribbons of length 3/4 yd, 1/3 yd and 1/2 yd.
To find the total ribbon she bought in yards we have to take the sum of all the fractions.
∴ (3/4) + (1/3) + (1/2) yards.
Now to sum these fractions we have to take LCM of the denominators which is 12.
So, { (3×3) + (1×4) + (1×6) }/12.
= (9 + 4 + 6)/12.
= 19/12 or 1 whole 2/3 yards of ribbon.

find the rank of a 5 x 6 matrix a for which ax = 0 has a two-dimensional solution space.
Therefore, the rank of matrix 'a' in this case would be 5.
To find the rank of a matrix, we need to perform row reduction to obtain its row echelon form (REF) or reduced row echelon form (RREF). However, since the matrix 'a' is not provided, I cannot perform the calculations or determine its rank.
The rank of a matrix is equal to the number of non-zero rows in its row echelon form or reduced row echelon form. If the system of equations 'ax = 0' has a two-dimensional solution space, it means that the rank of matrix 'a' is less than the number of columns (6) but greater than 4 (since the solution space is two-dimensional).

1039 85.9
1156 87.2
1218 87.8
1131 91.4
888 75.5
Using technology, the regression model obtained will be in the form :
y = bx + c
b = slope ; c = intercept
y = temperature ; x = chirps per minute
The regression model is :
ŷ= 43.28 + 0.0390x
If outside temperature, y = 76 ; x will be ;
76 = 43.28 + 0.0390x
76 - 43.28 = 0.0390x
32.72 = 0.0390x
x = 32.72 / 0.0390
x = 838.97435

When buying advertiing time on televiion or in magazine, advertier calculate the cot per thouand (CPM) people reached by the ad. If the cot of advertiing wa $100,000 and the reach or circulation wa 10,000,000 people, what would be the CPM? (Note: M i the Roman numeral for 1,000. )
If the cost of advertising was $100,000 and the reach or circulation was 10,000,000 people, then the CPM is $10.
Cost per thousand (CPM), which is also called cost per mille, is a marketing word used to denote the price of 1,000 advertisement prints on one web page. If a publisher of a website charges $2.00 CPM, that means an advertiser must pay $2.00 for every 1,000 prints of its ad.
The CPM is calculated by dividing the cost of the advertisement by the number of people reached and then multiplying by 1000.
Given that the cost of advertising was $100,000 and the reach was 10,000,000 people, the CPM can be calculated as follows:
CPM = ($100,000 / 10,000,000) × 1000 = $10.
