Let X be the hip breadth for men. X follows Normal distribution with mean μ =14.8 and standard deviation σ =1.1
Here we have to find the hip breadth for men that separates the smallest 90% from the largest 10%
That is we have to find X that separates lower 90% area from upper 10%. For that we will first find z such that probability below it is 0.9 and above it 0.1
P(Z < z) =0.9
Using z score table to find z value
We do not have probability value exactly 0.9 so we will take probability close to 0.9 which is 0.8997 and corresponding z score is 1.28
So we have P(Z < 1.28) =0.9
Now using z=1.28, μ =14.8 and σ =1.1 we will find value of x
x = z*σ + μ
= (1.28 * 1.1) + 14.8
x = 16.208 rounding to nearest integer x= 16
The hip breadth that separates lower 90% area from upper 10% is 16 inch
Answer:
His teacher advised it because he did not have time to tutor Euler privately
Step-by-step explanation:
We know that
Euler in his autobiographical writings, talked about his tutor Johann Bernoulli. He claimed that his tutor was a very busy person who refused to give him private lessons, but gave him many valuable tips to start reading and studying more advanced math books on his own.
therefore
His teacher advised it because he did not have time to tutor Euler privately
Answer:
42%
Step-by-step explanation:
So the total amount of birds spotted are 140.
The amount of Blue Jays spotted is 59.
take 59/140
59/140 = 0.42
0.42 x 100 = 42
42% is the probability that papa sees a Blue Jay.
first you need to find the slope (m) using y2-y1/x2-x1.
-4-2/4-1= -6/3=-2
m=-2
then plug into the intercept form formula: y-y1=m(x-x1)
y-2=-2(x-1)
98 ÷ 5 = 19.6
19 × 5 = 95
98 - 95 = 3
98 <span>÷ 5 = 19 R3</span>
