Answer:
$3.40
Step-by-step explanation:
Look at image above...
X = # of cans of tomatoes, y = # of cans of corn
x + y = 32.....y = 32 - x
0.80x + 0.40y = 18
0.80x + 0.40(32 - x) = 18
0.80x + 12.8 - 0.40x = 18
0.80x - 0.40x = 18 - 12.8
0.40x = 5.2
x = 5.2 / 0.40
x = 13 <=== 13 cans of tomatoes were bought
leaving (32 - 13) = 19 cans of corn bought
Answer:
1-
P(X=1) = 1/36
P(X=2) = 3/36 = 1/12
P(X=3) = 5/36
P(X=4) = 7/36
P(X=5) = 9/36 = ¼
P(X=6) = 11/36
2-
7/36
Step-by-step explanation:
1-
Attached, you will find a table with the possible values of X.
(See table attached)
As we can see, there are 36 entries so,
<em>P(X=1) = 1/36
</em>
<em>
</em>
<em>P(X=2) = 3/36 = 1/12
</em>
<em>
</em>
<em>P(X=3) = 5/36
</em>
<em>
</em>
<em>P(X=4) = 7/36
</em>
<em>
</em>
<em>P(X=5) = 9/36 = ¼
</em>
<em>
</em>
<em>P(X=6) = 11/36
</em>
2-
It can be noticed that the only possible value of X which is divisible by 4 is 4 and there are 7 entries in the table, so
P(X divisible by 4) = P(X=4) = 7/36
Answer:
The most they can print is 800
Step-by-step explanation:
.5 N + 2.5M ≤ 6000
We are given N = 8000
Substitute this into the inequality
.5 (8000) + 2.5M ≤ 6000
4000 +2.5M≤ 6000
Subtract 4000 from each side
4000-4000 +2.5M≤ 6000 -4000
2.5M≤ 2000
Divide each side by 2.5
2.5M/2.5≤ 2000/2.5
M ≤800
5 1/2 * 1 2/5
They can be turned into improper fractions to make multiplying easier. Do this by multiplying the whole number by the denominator and then adding the numerator, and then putting that number over the given denominator.
11/2 * 7/5
The numerators are multiplied and the denominators are multiplied.
77/10
Now, reduce it back into a mixed number.
7 7/10
Hope this helps! :D
