Answer:
−9⋅(5j+k) = -45j -9k.
Step-by-step explanation:
Given : −9⋅(5j+k)
To find : distributive property.
Solution : −9⋅(5j+k)
By distributive property a( b +c ) = a*b + a*c.
Then −9⋅(5j+k) = -9 *5j + (-9 *k)
−9⋅(5j+k) = -45j -9k.
Therefore, −9⋅(5j+k) = -45j -9k.
The answer is 9
both 81 and 63 are dividable by 9, and nothing higher
Answer:
20. C, 21. A, 22. B
Step-by-step explanation:
20. Terms are numbers with variables next to them.
21. T can be anything. It can't be irrational because timers have a certain number. So for example, swimmer swims in 10 seconds, 18.5 seconds, 18.67 seconds, and so on.
22. If you solve 3x ≥ -12 and 8x ≤ 16, you get 3x ≥ -12; x = -4, and 8x ≤ 16; x = 2.
Hope it Helps!

Step-by-step explanation:
Answer:
0.09 average effect
Step-by-step explanation:
Given that the t statistics = 1.54
Sample size (n) = 25
Therefore, variance = t²/n
Variance = 1.54²/25
Variance = 2.372/25
Variance = 0.09
