Hello! My name is Chris and I’ll be helping you with this problem.
Date: 9/28/20 Time: 9:51 am CST
Answer:
5 hours
Explanation:
Step 1: Set up an equation:
35 + 3x = 50
Step 2: Solve:
35 + 3x = 50 Subtract 35 from both sides
3x = 15 Divide 3 from both sides
x = 5
I hope this helped answer your question! Have a great rest of your day!

Ronald drives his car down a road for 4 miles then turns around and drives back towards his starting point for 1 mile. what
is his distance traveled?
Answer:
5 miles
Step-by-step explanation:
4+1 =5
Answer:
5 miles
Step-by-step explanation:
Ronald's total distance traveled would be 5 miles because he travels 4 miles in one direction and 1 mile in another. 4+1= 5
His displacement would be 3 miles because he went, let's say, right 4 miles and then turned around and went left for 1 mile. This puts Ronald at 3 miles from his starting point.
Formalize the following argument by using the given predicates and then rewriting the argument as a numbered sequence of statements. Identify each statement as either a premise, or a conclusion that follows according to a rule of inference from previous statements. In that case, state the rule of inference and refer by number to the previous statements that the rule of inference used. Dogs bark at cats. Max is a dog. Moonbeam is a cat. Therefore, Max barks at Moonbeam. Predicates: B(x,y) = "x barks at y". D(x) = "x is a dog". C(x) ="x is a cat". The common domain of discourse is all animals.
Based on the inference, we can conclude that Max barks at Moonbeam.
What's the inference?To formalize the argument, we can use the given predicates and rewrite the statements as a numbered sequence, identifying each statement as either a premise or a conclusion that follows according to a rule of inference from previous statements. Here's the formalization:
Premise: Dogs bark at cats. (For all animals x and y, if D(x) and C(y), then B(x, y).)
Premise: Max is a dog. (D(Max))
Premise: Moonbeam is a cat. (C(Moonbeam))
Conclusion: Max barks at Moonbeam. (B(Max, Moonbeam))
In this formalization, statement 4 is the conclusion, and it follows from statements 1, 2, and 3. The rule of inference used is the universal instantiation, which allows us to instantiate the universal statement from statement 1 to a specific case involving Max (statement 2) and Moonbeam (statement 3). Therefore, we can conclude that Max barks at Moonbeam.

Answer: D
Step-by-step explanation:
Random samples of size 81 are taken from an infinite population whose mean and standard deviation are 200 and 18, respectively. The distribution of the population is unknown. The mean and the standard error of the sampling distribution of sample mean are
Select one:
a. 200 and 18
b. 9 and 2
c. 81 and 18
d. 200 and 2 Correct
Answer:
D 200 and 2
Step-by-step explanation:
standard error of the sampling distribution of sample mean is expressed using the formula;
Standard error of the mean = S/√n where;
S is the standard deviation
n is the sample size
Given
S = 18
n = 81
SEM = 18/√81
SEM = 18/9
SEM = 2
The mean of the distribution according to the question is 200.
Hence the mean and the standard error of the sampling distribution of sample mean are 200 and 2 respectively.

At CVS, the tax paid was $2.45, which was 7% of the cost. What was the cost of the items purch
ased?
'Percentage' is obtained by multiplying 2.45 by - 7%.
- 7% × 2.45 =
(- 7 ÷ 100) × 2.45 =
(- 7 × 2.45) ÷ 100 =
- 17.15 ÷ 100 =
- 0.1715 ≈
- 0.17;
How do we check the result?If - 7% × 2.45 = - 0.1715 =>
Divide - 0.1715 by 2.45...
... And see if we get as a result: - 7%.
Note:100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
n/100 = n%, any number.

One day 28 small and 12 large merchant spaces were rented. Another day, 30 small and 15 large spaces were rented. Write and evaluate an expression to show the total rent collected
Answer:
The expression which shows the total rent collected is S + L
The total rent collected is 85 of different size
Step-by-step explanation:
Let us list the given information
→ On one day: 28 small and 12 large merchant spaces were rented
→ Another day: 30 small and 15 large spaces were rented
Let S represents the small spaces and L represents the large spaces
∴ The total rent collected = S + L
∵ S in the two days = 28 + 30
∴ S = 58
∵ L in the two days = 12 + 15
∴ L = 27
Substitute The values of S and L in the expression of the total above
∴ The total rent collected = 58 small spaces + 27 large spaces
∴ The total rent collected = 85 of different size
The expression which shows the total rent collected is S + L
The total rent collected is 85 of different size

Mr. Samson received 56% votes.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here Mr. Samson receives 56 votes out of 100 thus we have in percentage terms as 56/100 × 100=56%
Hence, Mr. Samson received 56% votes.

Answer:
No
Step-by-step explanation:
The vertical line test can be used to decide whether a relation is a function. If you draw a vertical line x = a, the line will intersect the graph of the relation twice for all a > 0. This just means that there are values of x where there is more than one y value, so this is not a function.
