Answer:
Step-by-step explanation:
Let X be the random variable that represents a score of Susan. We know that X has a normal distribution with average score of 225 and a standard deviation of 13. For n = 16 games, the average score 
has a normal distribution with mean of 225 and a standard deviation of 
. Besides, the z-score related to 220 is (220-225)/3.25=-1.5385, and the z-score related to 228 is (228-225)/3.25= 0.9231. Therefore, we are looking the probability 
= 0.76
You’re answer should be 9-7 hope this helped
Answer:
Option A Gender and garlic preference.
Step-by-step explanation:
We have been given Charmaine made traditional pizzas for her classmates. She recorded whether the students wanted garlic on their pizza.
For two-way table we need two Data
So, gender and garlic preference is sufficient to form two-way table
She will use gender in first row and garlic preference in first column.
Gender Garlic preference
Male here male who needs garlic
Female here female who need garlic.
Therefore, option A is correct.
The system:
y = 3 x - 7
15 x - 5 y = 14
---------------------
Using the substitution method:
15 x - 5 · ( 3 x - 7 ) = 14
15 x - 15 x + 35 = 14
0 · x = 14 - 35
0 · x = - 21
x , y ∈ ∅
Answer:
D ) There is no solution.
You can add them like this:
so if 156 + 213 + 109 was the equation then you would
first put them in order from biggest to smallest
213
156
+109
-----------
then add:
¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )
then you get the answer 478!
hope that helps :)
