Answer:
Step-by-step explanation:
Answer:
The two numbers are
4
and
6
.
Explanation:
Let one number be represented as
x
and the other as
y
.
According to the problem:
x
=
2
3
y
and
x
+
y
=
10
From the second equation we get:
x
+
y
=
10
∴
y
=
10
−
x
(subtracting
x
from both sides)
Replacing the value of
y
in the first equation we get:
x
=
2
3
y
x
=
2
3
(
10
−
x
)
Multiplying both sides by
3
we get:
3
x
=
2
(
10
−
x
)
Opening the brackets and simplifying we get:
3
x
=
20
−
2
x
Add
2
x
to both sides.
5
x
=
20
Divide both sides by
5
.
x
=
4
Since from the second equation we have:
x
+
y
=
10
substituting
x
with
4
we get:
4
+
y
=
10
Subtract
4
from both sides.
y
=
6
The number could either be 240 or 204. This is because anywhere below 250 would round down, thus, 240 and 204 would round down to 200. Not sure if I read the question correctly, so reply if I didn't!

Answer: d) 2.5
<u>Step-by-step explanation:</u>
The mean is 16 so it has a z-score is 0
The standard deviation is 4 so:
- z-score of 1 is: 16 + 4 = 20
- z-score of 2 is: 20 + 4 = 24
- z-score of 3 is: 24 + 4 = 28
Notice that 26 is between the z-scores of 2 and 3 = 2.5
