if t34 = -4.322 and α = 0.05, then what is the approximate of the p-value for a left-tailed test?

Answers

Answer 1

Since the t-score is negative and very large in absolute value, the p-value will be smaller than the α = 0.05. Therefore, the approximate p-value for this left-tailed test is less than 0.05.

To find the approximate p-value for a left-tailed test with t34 = -4.322 and α = 0.05, we need to look up the area to the left of -4.322 on a t-distribution table with 34 degrees of freedom.
Using a table or a statistical calculator, we find that the area to the left of -4.322 is approximately 0.0001.
Since this is a left-tailed test, the p-value is equal to the area to the left of the observed test statistic. Therefore, the approximate p-value for this test is 0.0001.
In other words, if the null hypothesis were true (i.e. the true population mean is equal to the hypothesized value), there would be less than a 0.05 chance of obtaining a sample mean as extreme or more extreme than the one observed, assuming the sample was drawn at random from the population.

Answer:

x = 5

Step-by-step explanation:

__________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

[tex]a^x \times a^y = a^{x+y}[/tex]In an equation , if the bases are same in both L.H.S. & R.H.S. then , the power of the bases on both the sides of equation should be equal. For e.g. : [tex]a^x = a^y[/tex]  ⇒  [tex]x = y[/tex]  [∵ Bases are equal on both the sides]

__________________________________________________________

[tex]4 \times 8^{2x+1} = 32^{x+2}[/tex]

Lets express it in terms of 2.

[tex]=> 2^2 \times 2^{3 (2x+1)} = 2^{5(x+2)}[/tex]

[tex]=> 2^2 \times 2^{6x+3} = 2^{5x+10}[/tex]

[tex]=> 2^{2 + 6x+3} = 2^{5x+10}[/tex]

[tex]=> 2^{6x+5} = 2^{5x+10}[/tex]

Here the bases on both the sides are equal. Hence ,

[tex]=> 6x + 5 = 5x + 10[/tex]

[tex]=> 6x - 5x = 10 - 5[/tex]

Find the number of terms and the degree of this polynomial.

Answers

Answer:

Number of terms = 3

Degree = 6

Step-by-step explanation:

A polynomial is a mathematical expression that gives the detailed combination of variables with their coefficients, their positive exponential, and other variables using the operations of subtraction, addition, and multiplication

The number of terms in a polynomial is the number of different powers of added or subtracted in the expression

Therefore, the number of terms in the expression -3·s⁶ + 2·s⁴ + 3·s³ is 3 terms

Number of terms = 3

The degree of a polynomial is given by the highest power of the variables in the polynomial. Therefore, the degree of the given polynomial is 6

Degree = 6

At a car dealership, salespeople earn a 5% commission on the first $10,000 of every sale, plus a 3% commission on any amount over $10,000. A salesperson sold a car for $12,300. What was the total commission on the sale? help me due today

Answers

Answer:

The total comission on the sale was $375.

Step-by-step explanation:

Since the salesperson sold the car for $12,300, the total comission on the sale would be equal to the 5% of $10,000 plus the 3% of the remaining amount which would be:

Total comission=(10,000*5%)+(12,500-10000)*(3%)

Total comission=500+(2,500*3%)

Total comission=300+75

Total comission=375

According to this, the answer is that the total comission on the sale was $375.

Your teacher is giving a test that has 5 more four-point questions than six-point questions.
The test is worth 120 points. Which system represents this information?​

Answers

Answer:

x-y=5

4x+6y=120

Step-by-step explanation:

let x = # of 4-point questions

ley y = # of 6-point questions

# of 4-point questions is 5 more than # of 6-point questions

x=y+5 or x-y=5

now there's the matter of the points. Since each x is worth 4 points and each y is worth 6 points, they total number of points have to add up to 120, therefore:

4x+6y=120

The System of Equation is

x-y=5

4x+6y=120

What is Algebra?

Which of the following sets of sides does not form a right triangle?
6.8.10
8.15, 17
7.24.26
5, 12, 13?

Answers

Answer:

7, 24, 26

Step-by-step explanation:

6 squared is 36 and 8 squared is 64. Add them together and you get 100, which is 10 squared. Do the same for the other ones and you'll notice that 7 squared and 24 squared added together is 625, which is not 26 squared. In my head 25 squared is 625(check if you don't believe me) so I know that the answer is the third one. The basic formula for a right triangle is a^2 + b^2 = c^2, and that's how you find if three numbers form a right triangle or not. Hope this helps :)
