The product of 7.69x5 would be less than it's estimate of 8x5 because 8x5=45 and 7.69x5=38.45 and so 38.45 is less than 45.
6x+4y+9
This is written in y=mx+b format
I hope this helps!!!!!
Answer: The critical value for a two-tailed t-test = 2.056
The critical value for a one-tailed t-test = 1.706
Step-by-step explanation:
Given : Degree of freedom : df= 26
Significance level :
Using student's t distribution table , the critical value for a two-tailed t-test will be :-
The critical value for a two-tailed t-test = 2.056
Again, Using student's t distribution table , the critical value for a one-tailed t-test will be :-
The critical value for a one-tailed t-test = 1.706
Answer:
Proportion states that the two ratios or fractions are equal
Given the statement:
The scale on map is 2 cm =25 miles.
Dave measured the distance to the next town at 5 cm.
We have to find the what miles away is the next town.
Let x be the distance in miles away is the next town.
By definition of proportion:
By cross multiply we get;
Simplify:
Divide both sides by 2 we get;
x = 6.25 miles
Therefore, 6.25 miles away is the next town.
Answer:
x = 8 and x = -3.
Step-by-step explanation:
-x^2 + 5x + 24 = 0 at the x intercepts.
Divide thru by -1:
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x - 8 = 0 , x + 3 = 0
x = 8 and x = -3.
