Determine if the side lengths 12, 13, and 13 form a triangle. If it is a triangle, classify it by its sides.It's not a triangle.
scalene triangle
isosceles triangle
equilateral triangle

Answers

Answer 1
Answer: it would be isosceles, since two of the sides are equal. if none of the sides were equal, it would be scalene, and if all of the sides were equal, it would be equilateral.

Logan is a salesperson who sells computers at an electronics store. He is paid a $1.25 commission for every computer sale he makes and he also makes a guaranteed base pay of $80 each day. Write an equation for P, in terms of x, representing Logan's total pay on a day on which he sells x computers.

Answers

Final answer:

The equation for Logan's total pay on a day he sells x computers is P = 80 + 1.25x.

Explanation:

To represent Logan's total pay on a day he sells x computers, we need to consider his base pay and commission. Logan's base pay is $80 per day. Additionally, he earns a commission of $1.25 for each computer he sells. Therefore, the equation for P, representing Logan's total pay, can be written as:



P = 80 + 1.25x

p=1.25x + 80


p is the pay and the 1.25 depends on how much computers he sells but he gets at least 80$ for his paycheck

Given a test statistic of t=2.315 of a left tailed test with n=8

Answers

Answer:

Null hypothesis: \mu =110

Alternative hypothesis:\mu \neq 110

The sample size on this case is n=8, then the degrees of freedom are given by:

df = n-1= 8-1=7

The statistic is given by:

t= (\bar X -\mu)/((s)/(√(n)))

For this case the value of the statistic is given t = 2.315

Since we are using a bilateral test the p value would be given by:

p_v = 2*P(t_(7)>2.315) =0.054

And we can use the following excel code to find it:

"=2*(1-T.DIST(2.315;7;TRUE))"

Since the p value is higher than the significance level given we FAIL to reject the null hypothesis. And the best conclusion would be:

0.05<P-value <0.10, fail to reject the null hypothesis

Step-by-step explanation:

Assuming this complete question :"Given a test statistic of t=2.315 of a left-tailed test with n=8, use a 0.05 significance level to test a claim that the mean of a given population is equal to 110.

Find the range of values for the P-value and state the initial conclusion 1 point) 0.05<P-value <0.10; reject the null hypothesis

0.05<P-value <0.10, fail to reject the null hypothesis

0.025 < P-value <0.05; reject the null hypothesis

0.025< P-value<0.05; fail to reject the null hypothesis"

For this case they want to test if the population mean is 110 or no, the systemof hypothesis are:

Null hypothesis: \mu =110

Alternative hypothesis:\mu \neq 110

The sample size on this case is n=8, then the degrees of freedom are given by:

df = n-1= 8-1=7

The statistic is given by:

t= (\bar X -\mu)/((s)/(√(n)))

For this case the value of the statistic is given t = 2.315

And we can use the following excel code to find it:

"=2*(1-T.DIST(2.315;7;TRUE))"

Since the p value is higher than the significance level given we FAIL to reject the null hypothesis. And the best conclusion would be:

0.05<P-value <0.10, fail to reject the null hypothesis

Alright, lets get started.

As per the scale, (1)/(4) '' = 1 '

Means 0.25 '' = 1 ' (symbol '' denotes inches and ' denotes feet)

As per the drawing, the dimention of bedroom is 3(1)/(2) '' and 5(1)/(4) ''.

Means

3(1)/(2) '' = 3 + (1)/(2) = 3 + 0.5 = 3.5''

converting into feet, we need to divide with 0.25.

Means the first dimension would be : (3.5)/(0.25) = 14 '

Converting 5(1)/(4) into decimal : 5 + 0.25 = 5.25

Similarly, the second dimension in feet would be : (5.25)/(0.25) = 21 '

Hence the dimension of bedroom will be 14 ft by 21 ft : Option A : Answer
