Answer:
(2*3)=6; 60= (2*3)*2*5 (prime factorization)
The numbers in the parenthesis can't be taken out because they are the HCF
So just move the 2 and the 5 on both sides and you'll get two pairs that are (6,30) and (12,30)
Answer:
answer D. $1.96
Step-by-step explanation:
Answer:
56.70
Step-by-step explanation:
first determine the tax
45 * 6% = 45*.06 = 2.70
Then determine the tip
45 * 20% = 45*.2 =9
Then add everything together
45+2.70+9 =56.70
Answer:
d. 52.5 million cases
Step-by-step explanation:
from the data output in the question, we have the regression equation to be
log y = -151.281 + 0.076577x
y is the number of hiv cases which is in millions
x is the year of the hiv case
x = 1998
we put the value of x in the regression equation
log y = -151.281 + 0.076577(1998)
log y = -151.281 + 153.000846
log y = 1.719846
since the result is in log form,
y = 52.5 million cases
7, 13, 19 and 25 have a common difference: 6.
6 added to 7 gives us 13; 6 added to 13 gives us 19, and so on.
Explicit formula: a(n) = 7 + 6(n-1), where 7 is the first term and n is the counter (1, 2, 3, ...).
The first term is 7 (given). This corresponds to n=1.
The second term is a(2) = 7 + 6(2-1), or 7 + 6, or 13. This corresponds to n = 2.
and so on.
