Expression: <span>t=2(2h/32)^1/2
Squaring on both sides,
t</span>² = 2(2h/32)
t² = 4h/32
t² = h/8
h = 8t²
Height of player 1 = 8(0.9)² = 6.48 Feet
Height of player 2 = 8(0.8)² = 5.12 Feet
Difference = 6.48 - 5.12= 1.36 Feet = 16.32 in
In short, Your Answer would be:16 Inches
Hope this helps!
Answer: 219.8 meters
Step-by-step explanation:
Since his stride measures 1.4 meters and the length of the field is 157 strides, then the length of the stride in meters is 157*1.4 meters.
= 219.8 meters
Answer:
y = -2x -8
Step-by-step explanation:
The equation for a line can be written in slope intercept form
y =mx+b where m is the slope and b is the y intercept
the slope is -2 and the y intercept is -8
y = -2x -8
Answer:
[0.875;0.925]
Step-by-step explanation:
Hello!
You have a random sample of n= 400 from a binomial population with x= 358 success.
Your variable is distributed X~Bi(n;ρ)
Since the sample is large enough you can apply the Central Limit Teorem and approximate the distribution of the sample proportion to normal
^ρ≈N(ρ;(ρ(1-ρ))/n)
And the standarization is
Z= ^ρ-ρ ≈N(0;1)
√(ρ(1-ρ)/n)
The formula to estimate the population proportion with a Confidence Interval is
[^ρ ± *√(^ρ(1-^ρ)/n)]
The sample proportion is calculated with the following formula:
^ρ= x/n = 358/400 = 0.895 ≅ 0.90
And the Z-value is ≅ 1.65
[0.90 ± 1.65 * √((0.90*0.10)/400)]
[0.875;0.925]
I hope you have a SUPER day!
You add up all the sides, so for example, the first 1, 5+4+5+4=18
