Answer:
No it is not a good prediction. Theoretical probability says that the answer would be 30 of the 60 (30/60) rolls would be even numbers.
Step-by-step explanation:
The probability of rolling an even number on a fair six sided die is 3/6 or 1/2 when simplified.
if john rolls the die 60 times, multiply the theoretical probability (1/2) by the number of rolls
(1 ÷ 2) x 60 = 30
∴ theoretical probability says that john would roll an even number 30 out of the 60 rolls

Answer: Median Mode Mean
Step-by-step explanation:
A normal distribution a symmetric distribution where most of the values lies around the central peak where Mean, median mode all lies together and the value of z=0 (as z-value given the distance of data values from mean with respect to the standard deviation).
i.e. Z-score of 0 has 50% of the area to the left and 50% area to the right.
Hence, at a z-score of 0.0 in a normal distribution Mean, Median and Mode all fall together.
Um where the problem or number?
Answer:
The area in factored form is
.
The area in standard form is
.
Step-by-step explanation:
The area of a rectangle is length times width.
So the area here is (x+2)(x-5).
They are probably not looking for A=(x+2)(x-5) because it requires too little work.
They probably want A in standard form instead of factored form.
Let's use foil:
First x(x)=x^2
Outer: x(-5)=-5x
Inner: 2(x)=2x
Last: 2(-5)=-10
---------------------Adding together:
.
The area in factored form is
.
The area in standard form is
.
Answer:
75 and 552 =627
Step-by-step explanation:
First=x
Second 7x+27
x+ 7x+27= 627
8x+27=627
8x=600
x=75
75*7+27 =525
525+27 = 552
