Answer:
x = 24
Step-by-step explanation:
10(x+12)=15x (Given)
10x + 120 = 15x (Distributive property of equality)
-5x = -120 (Subtraction property of equality)
x = 24 (Division property of equality)
Answer:
0.45576
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Standard Deviation = √variance
Mean = 50
= √9
= 3
z = 51 - 50/3
= 0.11111
Probability value from Z-Table:
P(x<51) = 0.54424
P(x>51) = 1 - P(x<51)
= 1 - 0.54424
= 0.45576
The probability that the dealer will sell 51 or more cars is 0.45576
Answer:
4
Step-by-step explanation:
Given that 


Now,


This can be written as
[as
]

[ by using equation (i)]
=4
Hence, 
i think this is the answer Simplifying h(t) = -16t2 + 20t + 6 Multiply h * t ht = -16t2 + 20t + 6 Reorder the terms: ht = 6 + 20t + -16t2 Solving ht = 6 + 20t + -16t2 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Divide each side by 't'. h = 6t-1 + 20 + -16t Simplifying h = 6t-1 + 20 + -16t Reorder the terms: h = 20 + 6t-1 + -16t
Answer:
36.51
Step-by-step explanation:
If Bailey ran four miles, then the time that is given for each of her miles should be added together to find out her total time.
9.05 + 8.24 + 10 + 9.22
You can break it down into chunks to make it easier for you:
9.05 + 8.24
= 17.29
___________
9.22 + 10
= 19.22
_________________________________________________
Then you can just add both values together to find out the total
_________________________________________________
17.29 + 19.22 = 36.51
