Answer:
First picture: -4,913
Second picture: 20.25
Step-by-step explanation:
-17^5/-17^2 = -17^3
-17 × -17 × -17 = -4913
4.5^5/4.5^3 = 4.5^2
4.5 × 4.5 = 20.25
Do you see how I had the same whole number on the top and bottom? (17 was on top and 17 was on bottom)
The exponents were those tiny numbers you saw.
Whenever you are dividing by the same whole number (-17/-17), you can subtract exponents.
When you multiply the same whole number, you can add the exponents.
Hope this helps! Best of luck :)
Answer:
Probability is 0.0174
Step-by-step explanation:
Given data
mean = 140
variance = 25
no of sample n = 49
to find out
probability of the sample
solution
standard deviation is
standard deviation =
standard deviation = 5
we mean by more than 1.7 millimeters so
mean (X1) = mean + 1.7 or mean - 1.7
so probability = X1 -mean/ ( standard deviation / )
probability = 140 -1.7 -140 / ( 5 / )
probability = - 1.7 / 35 = -0.048
probability = 140 + 1.6 -140 / ( 5 / )
probability = 1.7 /35 = 0.048
so required probability is i.e
= P(X1 < mean - 1.7 ∪ X1 > mean + 1.7 )
= 1 - P(mean -1.7 < X1 < mean +1.7 )
= 1 - P(-0.048 < X1 < 0.048 )
= 1 - 0.9826
= 0.0174
so required probability is 0.0174
Your answer is: y = (x - 6)(x - 2)
