Answer:
"and"
Step-by-step explanation:
Properly written, the word "and" separates the integer portion from the fractional portion of the number. If there is no "and", then there is no integer portion, so the number is a fraction less than 1.
<u>Examples</u>:
one <em>and</em> three tenths = 1 3/10
thirty-one thousandths = 31/1000
Answer:
b = -18
Step-by-step explanation:
Multiply both sides by -6/1 which is the reciprocal of -1/6
(-6/1)*(-1/6)b=3*(-6/1)
b=-18/1 = -18
The coordinates of point D is (0, 7)
<h3><u>solution:</u></h3>
The midpoint M of CD has coordinates (2, 5)
Point C has coordinates (4, 3)
To find: coordinates of point D
The midpoint of line AB conatining points
and
is given as:

Here in this problem,
Midpoint (C, D) = (2, 5)


Subsituting the values in formula we get,

On comparing both the sides we get,


Thus the coordinates of point D is (0, 7)
Answer:
Almost 2.5% of the students spent more than $275 in a semester.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 235
Standard deviation = 20
According to the standard deviation rule, almost 2.5% of the students spent more than what amount of money on textbooks in a semester?
95% of the measures are within 2 standard deviation of the mean. The other 5% are more than 2 standard deviations of the mean. Since the normal distribution is symmetric, 2.5% of those are below two standard deviations of the mean and 2.5% are more than two standard deviations above the mean.
235 + 2*20 = $275
Almost 2.5% of the students spent more than $275 in a semester.
The complete question in the attached figure
let
x-------> t<span>he number of ounces of pineapple juice
y------> </span><span>the number of ounces of grapefruit juice
we know that
x+y=32
x=2y+5-----> x-5=2y
using a graph tool
see the attached figure N 2
the solution is
x=23 ounces (</span>pineapple juice)<span>
y=9 ounces (</span>grapefruit juice)<span>
therefore
the answer is the option a</span>
