Answer:
the answer is 8
Step-by-step explanation:
add all four in n the half of the others 2 =1
The 85th percentile is a probability of 0.85 and its location is shown in the bell curve below
We need to look up on the z-table the value of z when P(Z<z) = 0.85 or P(Z>z) = 0.15
Value of z-score when p-value P(Z>z) = 0.15 is z = 1.0364
Next step is to use the formula of z-score to work out X
z-score = (X-μ) / σ
1.0364 = (X-80) / 15
1.0364 × 15 = X - 80
X = 15.546 + 80
X = 95.5
Most likely score that Ashley gets is 95.5
Answer:
A m = 48
B x = -24
C x = 16
Step-by-step explanation:
A. 1/6m - 3 = 5
1/6m = 5+3
1/6m = 8
multiply both side by 6
m = 8×6
m = 48
B. 2/3x-3 = 1/2 x-7
2/3 x - 1/2 x = -7 +3
1/6 x = -4
multiply 6 to the both side
x = -4×6
x= -24
C.x+x/2-4= x/4
x+x/2 - x/4 = 4
x + l/2 x - 1/4 x = 4
1/4 x = 4
multiply both side by 4
x= 4×4
x = 16
4.75.
the whole number is 4
circle 4 and see whether the number beside it
in this case its 7
(Any number that is 5 - 9 causes the number that you are rounding off to to increase)
( any number that is 4-1 causes the number that you are rounding off too to remain)
in this case since its 7 which more that 5 and the whole number increases therefore the final answer is 5.
Hope this helps! xD
would not mind if you put it as the brainliest answer
5x=2x+24
5x-2x=24
3x=24
x=24/3
x=8
Now you can verify by putting 8 in the x :)
