Answer:
His actual score is 15
Step-by-step explanation:
Here, we are interested in calculating Wayne’s actual score on the ACT
when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.
Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.
The formula for the z-score or standard score is given below;
z-score = (x - mean)/SD
where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6
So, substituting these values into the z-score equation, we have;
-0.5 = (x-18)/6
x-18 = 6(-0.5)
x -18 = -3
x = -3 + 18
x = 15
Hilda bought 15.11 lb of pork.
Step-by-step explanation:
Cost of Beef that Hilda bought = 4 17/20 = 4.85 lb
Cost of the total meat she bought = 19 24/25 = 19.96 lb.
To find the number of pounds of pork she bought, subtract.
Number of pounds of pork she bought = 19.96 - 4.85 = 15.11 lb.
You need to use the cross product method to find your answer :
1 pizza = 2 ½ cups
3 pizzas = × cups
((2 ½) • 3) ÷ 1 = × cups
7 ½ ÷ 1 = × cups
7 ½ = × cups
⇨ So your answer is: You would need to use 7 ½ cups of flour to make 3 handmade pizzas!
There you go. I really hope this helped, if there’s anything just let me know! ☻
