1. (15 points) In order to graduate from Ohio, you need to earn 3 points on an Algebra EOC or score remediation
free scores on the ACT and SAT math exams. The EOC exams are normally distributed with a mean of 703.27
and a standard deviation of 34.14. A score of 700 is needed to earn 3 points.
a. Fill in the values of each standard deviation above and below the mean, and make sure to add in the value
of the mean. Answers only are fine.

b. What would be the z-score for a 700 on the EOC? Show work.
c. You can also earn math credit by scoring a remediation free score on the ACT. ACT tests have a mean
value of 20.3 and a standard deviation of 5.52. What would be a z-score for a 22 on the ACT? Show work.

d. You can also earn math credit by scoring a remediation free score on the SAT. SAT tests have a mean value
of 547 and a standard deviation of 120. What would be a z-score for a 530 on the SAT? Show work.

e. Of the three testing options, which would be statistically easier to earn? Circle the answer and explain
your reasoning. EOC ACT SAT

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

no idea

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
