Since this is about finding the relative value of one parameter to another, our approach of solving this problem is by finding the ratio. In this way, we can compare the degree of their difference.

Ratio = Diameter of ball/Diameter of neuron
Ratio = 0.04 m/5×10⁻⁶ m
Ratio = 8,000
Therefore, the tennis ball is 8,000 times larger than the neuron,

Answer:

The tennis ball is 8000 times larger than the neuron.

Step-by-step explanation:

Average neuron is about 5\times10^{-6} meter in diameter .

A standard table tennis ball is 0.04 meter in diameter .

To tell about how many times as great is the diameter of a ball than a neuron, we will divide the tennis ball diameter by the neuron diameter.

\frac{0.04}{5\times10^{-6}}

We will move the 10^-6 in the numerator to positive 10^6

\frac{0.04\times10^{6}}{5}

= \frac{0.04\times1000000}{5}

= \frac{40000}{5}

= 8000 times.

So, the tennis ball is 8000 times larger than the neuron.

Help!! Find the value of f(3)
nekit [7.7K]

Answer:

Step-by-step explanation:

Start with where it tells you the value of x. The value of x is 3. That's given by    f(x) = f(3)

Next see which one of the functions you use. x > 0 is given by x^4 - 7. Since 3 is greater than zero you use x^4 - 7

f(3) means that wherever you see an x on the right side, you put a 3.

f(x) = x^4 - 7

f(3) = 3^4 - 7

f(3) = 81 - 7

f(3) = 74

A rectangle is 5 cm wider than twice its length. If the perimeter of the rectangle is 70 cm, then what is the area?
kifflom [539]

Step-by-step explanation:

The dimensions of the rectangle are two unknowns: The length "l" and the width "w"

The perimeter of a rectangle is found as P = 2*l + 2*w

We also know that the length is 5cm more than twice the width. l = 2*w + 5

These two equations gives us a system of linear equations.

P = 2*l + 2*w

l = 2*w + 5

We can use substitution to replace the "l" in the first equation with 2*w + 5

P = 2*(2*w + 5) + 2*w

P = 4*w + 10 + 2*w

P = 6*w + 10

we know the perimeter is 70

70 = 6* w + 10

subtract 10 from both sides

60 = 6* w

w = 10

Now that we know the width, we can find the length by substituting 10 for "w" in the second equation.

l = 2* 10 + 5

l = 20 +5

l = 25

the dimentions of the rectangle are 25cm x 10 cm

vlabodo [156]

Answer: 1.467

Step-by-step explanation:

Formula of Margin of Error for (n<30):-

E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 22

Level of confidence = 0.90

Significance level : \alpha=1-0.90=0.10

By using the t-distribution table ,

Critical value : t_{n-1, \alpha/2}=t_{21,0.05}= 1.720743

Standard deviation: \sigma=4

Then, we have

E=(1.720743)\dfrac{4}{\sqrt{22}}=1.46745456106\approx1.467

Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
