bro what kind of math is this
Step-by-step explanation:
sorry i cant help
Given that the<span> iq scores for large populations are centered at 100.
To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.
P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%

Answer:
Step-by-step explanation:
'll just help with proving whether she is correct.
First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult
so remember keep, change, flip
keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1
so 5/2 divided by 1/4 becomes
5/2 * 4/1
which then solved becomes
20/2 which is simplified to 10
Hope this helps :)

Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
-5 and 5 make
if you add them you will get 0
-5+5
=0
therefore
<h3>it's b</h3>
30÷4=7.5
45÷7.5=6
