Answer:
p=-6
Step-by-step explanation:
the first thing to do is to add all like terms for example p+
p would turn into
p+
p to make it so we can add them together which after we add both of those p's together we get
p which now we have
p+7=
p+5+4 which now we add 5 and 4 which we get 9 which now the equation looks like
p+7=
p+9 which now we subtract 7 from 9 and we are left with 2 so now the equation is
p=
p+2 which now we subtract
p from
p and we are left with -
p=2 which now we divide both sides by -
which makes the equation look like p=2÷-
which equals -6 so all we are left with is p=-6
Answer:
A) 34.13%
B) 15.87%
C) 95.44%
D) 97.72%
E) 49.87%
F) 0.13%
Step-by-step explanation:
To find the percent of scores that are between 90 and 100, we need to standardize 90 and 100 using the following equation:
Where m is the mean and s is the standard deviation. Then, 90 and 100 are equal to:
So, the percent of scores that are between 90 and 100 can be calculated using the normal standard table as:
P( 90 < x < 100) = P(-1 < z < 0) = P(z < 0) - P(z < -1)
= 0.5 - 0.1587 = 0.3413
It means that the PERCENT of scores that are between 90 and 100 is 34.13%
At the same way, we can calculated the percentages of B, C, D, E and F as:
B) Over 110
C) Between 80 and 120
D) less than 80
E) Between 70 and 100
F) More than 130
