Answer:
the two numbers are 19 and 6
Step-by-step explanation:
so we know that there are two numbers that added together give us 25
x+x=25
one of the numbers is twice the amount of the second plus 7
(2x+7)+x=25
simplify 2x+7+x
3x+7=25
subtract 7 from both sides
3x=18
divide 3 by both sides
x=6
and there is your answer.
Answer: No
Step-by-step explanation:
Considering significant: p <= 0.05
A multiple choice question has 18 possible answers, only one of which is correct.
which means that the probability is 1 out 18, so
p = 1/18 = 0.056
As 0.056 > 0.050
Then, it is not significant
Answer:
x=10.5
Step-by-step explanation:

4,025 ÷ 100 =
40.25
If he plays 3 matches a week for 9 weeks, you have to multiply 3&9.
