Answer:
Hip breadths less than or equal to 16.1 in. includes 90% of the males.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 14.5
Standard Deviation, σ = 1.2
We are given that the distribution of hip breadths is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.10.
P(X > x)
Calculation the value from standard normal z table, we have,
Hence, hip breadth of 16.1 in. separates the smallest 90% from the largest 10%.
That is hip breaths greater than 16.1 in. lies in the larger 10%.
Write their age ratio
E : F : G = 9 : 13 : 18
From the ratio above, we know that the sum of the ratio is
9 + 13 + 18 = 40
Count their money
For Eli, the ratio is 9
Eli's money = Eli's ratio/the sum of ratio × the sum of money
Eli's money = 9/40 × 800
Eli's money = 180
For Freda, the ratio is 13
Freda's money = Freda's ratio/the sum of ratio × the sum of money
Freda's money = 13/40 × 800
Freda's money = 260
For Geoff, the ratio is 18
Geoff's money = Geoff's ratio/the sum of ratio × the sum of money
Geoff's money = 18/40 × 800
Geoff's money = 360
So the answer:
Eli = £180
Freda = £260
Geoff = £360
Gasoline comes out to $47.12. Water comes out to be $7.96 and snacks are $3.10. Together it costs $58.18, therefore Mrs Jensen is wrong.
19/12 is the answer I hope you have a good day
Answer:
B=(C-D)/A
Step-by-step explanation:
You first subtract D from both sides, and then you get C-D=AB. To isolate the variable of B, you divide both sides by A, resulting in B=(C-D)/A.
