Let the number of matinee tickets they bought be t, the number of drinks bought be d and the number of popcorn bags bought be p, then the amount the spend on the number of drinks and bags of popcorn they bought is given by
.
The coefficients in the expression are 5.5 and 6 while the constant is 13 and the variables are d and p.
Answer:
4
Step-by-step explanation:
Frank has 5 cards.
Steve has 3 cards.
Pat has 9 cards.
Therefore, Pat has 4 more cards than Frank.
Hope this helps!
Hi!
To compare this two sets of data, you need to use a t-student test:
You have the following data:
-Monday n1=16; <span>x̄1=59,4 mph; s1=3,7 mph
-Wednesday n2=20; </span>x̄2=56,3 mph; s2=4,4 mph
You need to calculate the statistical t, and compare it with the value from tables. If the value you obtained is bigger than the tabulated one, there is a statistically significant difference between the two samples.
To calculate the degrees of freedom you need to use the following equation:
≈34
The tabulated value at 0,05 level (using two-tails, as the distribution is normal) is 2,03. https://www.danielsoper.com/statcalc/calculator.aspx?id=10
So, as the calculated value is higher than the critical tabulated one,
we can conclude that the average speed for all vehicles was higher on Monday than on Wednesday.
Given the following functions below,
Factorising the denominators of both functions,
Factorising the denominator of f(x),
Factorising the denominator of g(x),
Multiplying both functions,
Answer:
$13
Step-by-step explanation:
multiply 65 by 80 then divide by 100, you get 52, so subtract 65 from 52 you get 13
