Answer:
112°Step-by-step explanation:
Given∠DAY is a right angleand
m∠DAY = 1/2x + 34 Solving for xRight angle equals 90°, therefore

Solve the inequality for n
14 < n - 3
Answer:
n>17
Step-by-step explanation:
Step 1: Flip the equation.
n-3>14
Step 2: Add 3 to both sides.
n-3+3>14+3
The value of the n is more than 17 which is mathematically given in the form of an inequality equation as n > 17.
What is inequality?Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.
The inequality equation is given below.
14 < n - 3
Add 3 on both sides then we have
17 < n

A consulting firm submitted a bid for a large research project. The firm's management initially felt they had a chance of getting the project. However, the agency to which the bid was submitted subsequently requested additional information on the bid. Past experience indicates that for of the successful bids and of the unsuccessful bids the agency requested additional information.
1. What is the prior probability of the bid being successful (that is, prior to the request for additional information)?2. What is the conditional probability of a request for additional information given that the bid will ultimately be successful?3. Compute the posterior probability that the bid will be successful given a request for additional information (to 2 decimals).
Complete question is;
A consulting firm submitted a bid for a large research project. The firm's management initially felt they had a 50-50 chance of getting the project. However, the agency to which the bid was submitted subsequently requested additional information on the bid. Past experience indicates that for 74% of the successful bids and 39% of the unsuccessful bids the agency requested additional information.
1. What is the prior probability of the bid being successful (that is, prior to the request for additional information)?
2. What is the conditional probability of a request for additional information given that the bid will ultimately be successful?
3. Compute the posterior probability that the bid will be successful given a request for additional information (to 2 decimals).
Answer:
1) 0.5
2)0.74
3) 0.65
Step-by-step explanation:
1) Since we are told that they had a 50-50 chance of getting the project, Thus;
Probability of a successful bid is;
P(Successful bid) = 50/(50 + 50) = 50/100 = 0.5
2) We are told that for 74% of the successful bids, the agency requested additional information. Thus;probability of a request for additional information given that the bid will ultimately be successful is;
P(request|successful) = 74% = 0.74
3) For us to find the posterior probability that the bid will be successful given a request for additional information will be gotten using bayes theorem to get;
P(successful|request) = [P(request|successful) × P(Successful bid)] / [(P(request|successful) × P(Successful bid)) + (P(request|unsuccessful bid) × P(unsuccessful bid))]
P(request|unsuccessful bid) is given as 0.39 and P(unsuccessful) will be 0.5.
Thus;
P(successful|request) = (0.74 × 0.5)/[(0. 74 × 0.5) + (0.39 × 0.5)] ≈ 0.65

Suppose that you have read the following excerpt in a journal/research article:

Which of the following statements must be true based on this excerpt?
A. Employees attending two training sessions had the highest average sale
B. Employees with more training will always sell more units
C. The author's p-value was less than 5%
D. The author used a 10% Type-I Error probability
E. Our factor variable has only two levels since "No Training" cannot be a factor level
Consider the following hypothetical Multiple Comparisons of Means results for a study concerning differences in employee sales (in number of units sold) by training program format. Suppose that our sample consisted of sales employees and that we had sufficient evidence to reject the ANOVA null hypothesis.

Two Training Sessions 350.33 B
Which of the following statements is true based on the table above?
A. We do not need to consider the cost of the training sessions when choosing the best training program format
B. Training Program Format is our response/dependent variable
C. We expect an increase in sales when we implement one or two training sessions, but we do not expect a training program with two sessions to lead to significantly more sales than a program with only a single training session
D. Having a training program with three sessions will result in an increase in sales compared to having a training program with two sessions
Having a training program with two sessions yields significantly more sales than a training program with only one session

-2x - 9y = -3
-7x - 9y= -33
Set equal to y.
-2x - 9y = -3
-9y = 2x - 3
y = -2/9x + 3/9
y = -2/9x + 1/3
-7x - 9y= -33
-9y = 7x - 33
y = -7/9x + 33/9
y = -7/9x + 11/3
Set equal to each other
-2/9x + 1/3 = -7/9x + 11/3
Combine like terms.
5/9x = 10/3
Multiply by 9/5
x = 6
Plug x in.
y = -7/9(6) + 11/3
y = -42/9 + 11/3
y = -42/9 + 33/9
y = -9/9
y = -1

The bus fare in a city is People who use the bus have the option of purchasing a monthly coupon book for With the coupon book, the fare is reduced to $0.50. How many times must someone use the bus so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book? Express the total monthly cost to use the bus with a coupon book, f, as a function of the number of times in the month the bus is used, x. Then express the total monthly cost to use the bus without a coupon book, g, as a function of the number of times in the month the bus is used, x.
Answer:
26 times
Step-by-step explanation:
The question has missing details. However, the given parameters are
Given
Without Coupon
Bus Fare = $2.00
With Coupon
Coupon = $39.00
Bus Fare = $0.50
Represent the number of fares with x
Without Coupon, cost of fares is
Cost = 2x
i.e.
f(x) = 2x
With Coupon, cost of fares is
Cost = 39 + 0.5x
i.e.
g(x) = 39 + 0.5x
To calculate when both fares will be equal, we must have:
f(x) = g(x)
2x = 39 + 0.5x
Collect like terms
2x - 0.5x = 39
1.5x = 39
Solve for x
x = 39/1.5
x = 26
This implies that, for both cost to be equal, the person must go 26 times

What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The system of given equations following as:
y = - 2x + 7 ....(i)
y = 3x - 8 ....(ii)
We have to determine the solution to the given system using substitution or elimination.
The required solution using the substitution method would be as;
Substitute the value of the equation y = 3x - 8 in equation (ii), and solve for x
3x - 8 = - 2x + 7
3x + 2x = 7 + 8
5x = 15
x = 15/5
x = 3
Substitute the value of x = 3 in equation (ii), and solve for y
y = 3(3) - 8
y = 9 - 8
y = 1
Thus, the solution to the given system of equations is (3,1).

1. A person spends1/4 -part of his
income on food, 2/3part on house
rent and remaining * 630 on other
items. Find his house rent.
(a) * 2050
(b) 5040
(c) * 1000
(d) None of these
Answer:
*2520
Step-by-step explanation:
A quarter of him income was spent on food
X (representing his income) - x/4= 3x/4
Then 2/3 was spent on house rent. Notice the, the question didnt say 2/3 of his income. Therefore it would be 2/3 of what is remaining after he pays for food.
2/3 * 3x/4= x/2
3x/4-x/2=x/4.
The remaining after all expenses are paid is 630. So:
x/4=630
x=630*4
x=2520
1/4 + 2/3 + 1/12 = 1
That is fraction on
Food + house rent + other items = Total amount
If 1/12 = 630.............. equation 1
Then 1/4 + 2/3 = 11/12
11/12= x................. equation 2
Cross multiply equation 1 & 2
1/12*x = 1155/2
To find x, cross multiply again
2x = 13860
x = 13860/2
x = 6930
This means that 11/12 + 1/12 = 6930 + 630
= 7560
Therefore 2/3(fraction for house rent)*7560(total amount)=5040
Answer is 5040
