Step-by-step explanation:
16 matches=100%
what about,12 matches=?
you then cross multiply
12/16×100%=75%
=75%
Answer:
The midpoint of XY is point
M(�12, 5). If the coordinates
of X are (3, �3), what are the
coordinates of Y ?
----
Each coordinate of the midpoint is the average
of the corresponding endpoint coordinate.
----
Solve:
Let the coordinates of Y be (x,y)
---
(3+x)/2 = -12
3+x = -24
x = -27
----
(-3+y)/2= 5
-3+y=10
y = 13
---
Coordinates Y: (-27,13)

75/15=5 so the answer would be 5 months
Answer: I assume you mean surface area of a sphere.
The formula is 4πr²
If radius=3, then:
4 times
times 3²
4 times
times 9
= 113.142857
Rounded to 1 decimal place = 113.1
<u>NOTE: In place of π you can also use 3.14.</u>
Answer:
The diagram is attached below.
Step-by-step explanation:
A normal distribution mean 0 and standard deviation 1 is known as the standard normal distribution.
So, the readings on the thermometers (denoted by <em>Z</em>) follows N (0, 1).
It is provided that 2.7% of the thermometers are rejected because they have readings that are too high and 2.7% are rejected because they have readings that are too low.
This implies that:

The value of <em>z</em> associated to both these probabilities are:
<em>z</em> = 1.93.
That is,

*Use a <em>z</em>-table.
The diagram for the two readings that are cutoff values separating the rejected thermometers from the others is attached below.
