Step-by-step explanation:
and you get it by multiplying 9×4 keep the answer on paper then do 2×2 which is 4 subtract the two answers and subtract 7 and then you get 25, your welcome
Answer: first: 1/6 second dice: 4/6
Step-by-step explanation:
So we know that a dice have the numbers 1,2,3,4,5, and 6 .
So the the probability that first die rolled 2 is 1/6 because there appears only on 2 .
and the probability that the second dice rolled a number greater than 2 is 4/6 or 2/3 because there are 4 numbers greater than 2 out of the 6 total .
Test statistic = (mean 1 - mean 2) / sqrt( dev1/n1 + dev2/n2)
Mean 1 = $16.75
mean2 = $16.25
dev1 = $1.00
dev2 = $0.90
n1 = 80
n2 = 60
Test stat = (16.75 - 16.25) / sqrt(1/80 + 0.95/60)
Test stat = 3.01
The answer is B. 3.01
Answer:
x=32
Step-by-step explanation:
x/2-7=9
1/2x-7=9
add seven to both sides
1/2x=16
multiple both sides by two
x=32
⭐️- Remember that slope formula is y=mx+b
1. Know that the m is (-3)
2. 4=(-3)(9)+b
3. 4=(-27)+b
4. b=31
5. y=(-3x)+31
6. y=3x-31*
*whenever it is finding a perpendicular, you switch the signs; when it is finding a parallel, you leave it alone
