Answer:
Formula for nth term in Arithmetic sequences is:
where a is the first term, d is the common difference and n is the number of terms.
As per the statement:
The rule for the pattern is add 4.
As the first term in line says the first term i,e 7
common difference(d)= 7
As the Jenna number is 8th in line.
Series we get;
7, 11, .........
We have to find the 8th term.
n = 8, a = 7 and d = 4
Using above formula:
Therefore, 35 number should Jenna say.
The price of an item has dropped to $84 today. yesterday it was $120 . find the percentage decrease.
Let
s-------> <span>represent the number of sheep
g-------> </span><span>represent the number of goats
we know that
1) </span><span>Morgan moves no more than 26 of her sheep and goats into another field
so
(s+g) </span><span>≤ 26------> inequality 1
2) </span><span>Fewer than 14 of her animals are sheep
so
s < 14-------> inequality 2
therefore
the answers are
</span><span>B.) s < 14
</span><span>D.) s + g ≤ 26</span>
In the science class,
there are 3 girls and 1 boy (grade 7)
and 5 girls and 5 boys (grade 8)
There is a total of 14 pupils being 8 girls and 6 boys
The probability of choosing a boy will be
Which can be simplified into
by
dividing 2 from the numerator as well as the denominator.
