<em><u>Expression that represent the show the total cost for any number of rose bushes and tomato plant is:</u></em>
<em><u>Solution:</u></em>
Let "x" be the number of roses bush
Let "y" be the number of tomato plant
Cost of 1 rose bush = $ 5
Cost of 1 tomato plant = $ 2
To find: Expression that represent the show the total cost for any number of rose bushes and tomato plant
Total cost = number of roses bush x Cost of 1 rose bush + number of tomato plant x Cost of 1 tomato plant
Thus the expression is found where, x and y are the number of rose bush and tomoato plant bought respectively
Answer:
ACT Score performed better.
Step-by-step explanation:
Given :
ACT :
Mean score, μ = 21.2
Standard deviation, σ = 5.1
Score, x = 26
SAT :
Mean score, μ = 1498
Standard deviation, σ = 347
Score, x = 1800
To know which score is better, we obtain the standardized, Z score of the two examination :
Zscore = (x - μ) / σ
ACT Zscore :
(26 - 21.2) / 5.1
Zscore = 4.8 / 5.1 = 0.941
ACT Zscore = 0.941
SAT Zscore :
(1800 - 1498) / 347
Zscore = 302 / 347 = 0.870
SAT Zscore = 0.870
The student with the higher Zscore performed better :
ACT Zscore > SAT Zscore
I’m not completely sure but B or C
