Answer:
12
Step-by-step explanation:
8/1 ÷ 2/3
Keep the first fraction and flip the second one: 8×3/ 1×2
Multiply top and bottom: 24÷2
Simplified to be 12
I believe the value is 256
If you square 2 four times you will get 16
If you if you square 16 by two you will get 256 as your answer. Hope this helps!
<span>A) 2x - 7y = 13
B) 3x + y = 8
Multiplying equation B by 7
B) 21x + 7y = 56 then adding it to A
</span><span>A) 2x - 7y = 13
23x = 69
x = 3
y = -1
</span>
98 minus 6 equals 92. 92 divided by 4 equals 23
Answer:
(78, 80)
Step-by-step explanation:
Given a normal distribution :
Mean = 79 seconds
Standard deviation = 0.5 seconds
Using the empirical rule :
95% of her finishing times :
According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.
Hence ;
The interval will be defined as ;
Mean ± 2(standard deviation)
79 ± 2(0.5)
79 ± 1
(79 - 1) ; (79 + 1)
78 ; 80
