Answer:

See below

Step-by-step explanation:

When changing from scientific notation to standard, you want to look at the exponent.

If exponent is positive, move decimal that many times to the right.

If negative, move to the left.

7.875 x 10^4

Exponent is positive so move to the right.

78750

4.53 x 10^-4

Exponent is negative so move to the left.

0.000453

8.9 x 10^-7

Exponent is negative so move to the left

.00000089

Lelu [443]

Answer:

45 miles

Step-by-step explanation:

Use the Pythagorean Theorem. Imagine a line connecting the ends of the right angle you made by driving. It would make a right triangle. You are trying to find the hypotenuse. Use the formula a^{2} +b^{2} =c^{2}. Square 27, or multiply 27 by 27, to get 729. Add this to the square of 36, 1296. So c^{2} = 2025. Find the square root of 2025. \sqrt{2025} = 45. Hope this helped ^^

A meteorologist who sampled 4 thunderstorms found that the average speed at which they traveled across a certain state was 16 mi
DENIUS [597]

Answer:

The  90 % confidence  interval  for the mean population is (11.176  ; 20.824 )

Rounding to at least two decimal places would give 11.18 , 20.83

Step-by-step explanation:

Mean = x`= 16 miles per hour

standard deviation =s= 4.1 miles per hour

n= 4

\frac{s}{\sqrt n}  =  4.1/√4= 4.1/2= 2.05

1-α= 0.9

degrees of freedom =n-1=  df= 3

∈ ( estimator  t with 90 % and df= 3 from t - table ) 2.353

Using Students' t - test

x`±∈ * \frac{s}{\sqrt n}

Putting values

16 ± 2.353 * 2.05

= 16 + 4.82365

20.824  ;        11.176

The  90 % confidence  interval  for the mean population is (11.176  ; 20.824 )

Rounding to at least two decimal places would give 11.18 , 20.83
