what is a conditional statement
Answers
Answer:
A conditional statement is false if hypothesis is true and the conclusion is false.
Step-by-step explanation:
Conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.
What is Mathematical Reasoning?Reasoning in maths is the process of applying logical and critical thinking to a mathematical problem in order to work out the correct strategy to use in reaching a solution
A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.
For this conditional statement, P is called the hypothesis and Q is called the conclusion.
“If P then Q” means that Q must be true whenever P is true.
We have a conditional statement If it is raining, we will not play.
Let, P: It is raining and Q: we will not play.
Then; If P is true, that is, it is raining and Q is false, that is, we played, then the statement P implies Q is false.
Hence, conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.

#SPJ2
The sample observations on stabilized viscosity of asphalt specimens are 2781, 2900, 3013, 2856 and 2888. Suppose that for a particular application, it is required that true average viscosity be 3000. Does this requirement appear to have been satisfied? State and test the appropriate hypothesis at α = 0.05.
Answers
Answer:
there is no sufficient evidence to prove that viscosity is not 3000
Step-by-step explanation:
Let's state the hypothesis.
Null hypothesis; H0: μ = 3000
Alternative hypothesis; μ ≠ 3000
The sample mean is;
x = (2781 + 2900 + 3013 + 2856 + 2888)/5 = 2887.6
Standard deviation σ = √variance = √[(2781 - 2887.6)² + (2900 - 2887.6)² + (3013 - 2887.6)² + (2856 - 2887.6)² + (2888 - 2887.6)²)(1/(5 - 1))]
σ = √((1/4)(11363.56 + 153.76 + 15725.16 + 998.56 + 0.16)
σ = 84.026
Formula for test statistic is given as;
t = (x - μ)/σ
t = (2887.6 - 3000)/84.026
t = -1.338
From online p-value calculator from t value attached, using DF = 5 - 1 = 4, two tail and a significance level of 0.05,we have;
The p-value is 0.251896.
This is greater than the significance level of 0.05.
Thus, we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to prove that viscosity is not 3000

Please help quickly!!:)) Appreciate it x+y=6 y+4=x Choices: (11/2, 1/2) (5, 1) (21/2, 11/2) (1, 5)
Answers
Answer:
B: (5,1)
Step-by-step explanation:
So we have the system of equations:
[tex]x+y=6\text{ and}\\y+4=x[/tex]
We can solve this system using substitution.
Substitute the second equation into the first. Use x. So:
[tex](y+4)+y=6[/tex]
Combine like terms:
[tex]2y+4=6[/tex]
Subtract 4 from both sides:
[tex]2y=2[/tex]
Divide both sides by 2:
[tex]y=1[/tex]
So, the value of y is 1.
To find x, substitute this back into the second equation:
[tex]y+4=x[/tex]
Substitute 1 for y:
[tex]1+4=x[/tex]
Add:
[tex]x=5[/tex]
Therefore, our answer is (5,1).
The answer is B.
And we're done!
Evaluate the geometric series or state that it diverges. sigma^infinity_k=0(8/9)^k Select the correct choice below and, if necessary, fill in the answer box to complete your choice. sigma^infinity_k=0(8/9)^k The series diverges.
Answers
The series converges, since |8/9| = 8/9 < 1.
Let [tex]S_n[/tex] denote the n-th partial sum of the series,
[tex]S_n=\displaystyle\sum_{k=0}^n\left(\frac89\right)^k[/tex]
[tex]S_n=1+\dfrac89+\left(\dfrac89\right)^2+\cdots+\left(\dfrac89\right)^n[/tex]
Multiply both sides by 8/9:
[tex]\dfrac89S_n=\dfrac89+\left(\dfrac89\right)^2+\left(\dfrac89\right)^3+\cdots+\left(\dfrac89\right)^{n+1}[/tex]
Subtract this from [tex]S_n[/tex] to eliminate all but the first term in
[tex]S_n-\dfrac89S_n=1-\left(\dfrac89\right)^{n+1}[/tex]
Solve for [tex]S_n[/tex]:
[tex]\dfrac19S_n=1-\left(\dfrac89\right)^{n+1}[/tex]
[tex]S_n=9-9\left(\dfrac89\right)^{n+1}[/tex]
As [tex]n\to\infty[/tex], the exponential term vanishes, so that
[tex]\displaystyle\lim_{n\to\infty}S_n=\sum_{k=0}^\infty\left(\frac89\right)^k=\boxed{9}[/tex]

Greg is saving to buy a tablet that costs $235. He already has $25 saved up. Each week, Greg earns $15 babysitting and $25 as a cashier, but he spends $10 on lunches. Write and solve an equation to find how many weeks it will take Greg to have enough money saved to buy the tablet.
Answers
Answer:
235=30x-25
Step-by-step explanation:
235+25=30x-25+25
260=30x
260/30=30x/30
x=8.66 or 9 weeks
The equation is 30x + 25 = 235. And the number of weeks will be 7.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
Greg is saving to purchase a tablet that costs $235. He as of now has $25 set aside. Every week, Greg procures $15 looking after children and $25 as a clerk, however, he burns through $10 on snacks.
Let x be the number of weeks. Then the equation is given as,
25x + 15x - 10x + 25 = 235
Simplify the equation, then the number of weeks is given as,
25x + 15x - 10x + 25 = 235
30x = 235 - 25
30x = 210
x = 210 / 30
x = 7 weeks
The equation is 30x + 25 = 235. And the number of weeks will be 7.

The perimeter of the rectangle below is 94 units. Find the length of side PS.
Write your answer without variables.
Answers
Answer:
PS = 26 units
Step-by-step explanation:
Perimeter of rectangle = 94
2(4z - 2 + 3z) = 94
2(7z - 2) = 94
14z - 4 = 94
14z = 94 + 4
14z = 98
z = 98/14
z = 7
QR = 4z - 2 = 4*7 - 2 = 28 - 2 = 26
PS = QR (Opposite sides of rectangle)
PS = 26 units
