There are several information's of immense importance already given in the question. Based on those information's, the answer can be easily deduced.

<span>1.00 in. = 2.54 cm
We also know that
1 mile = </span>63360 inch
So
7 mile = 63360 * 7 inch
           = 443520 inch
Then
1 inch = 2.54 cm
443520 inch = 2.54 * 443520
                     = 1126540.80 cm
So
7 mi = 1126540.80 cm.

I hope that this is the answer that you were looking for and the answer has actually come to your desired help. I hope that the procedure is also simple enough for you to understand.

The answer is 11.265408 km.

To calculate the number of kilometers, we will use several conversions:
A) 1 mi = 63,360 in
B) 1 in = 2.54 cm
C) 1 cm = 0.00001 km

A) 1 mi = 63,360 in
    7 mi = 63,360 in · 7 = 443,520 in

B) 1 in = 2.54 cm
    443,520 in = 2.54 cm · 443,520 = 1,126,540.80 cm

C) 1 cm = 0.001 km
    1,126,540.80 cm = 0.00001 km · 1,126,540.80 = 11.265408 km

Answer:

The 90 % confidence limits are (-2.09, 8.09).

Since the calculated values do not lie in the critical region we accept our null hypothesis.

Step-by-step explanation:

The null and alternative hypothesis are given by

H0: σ₁²= σ₂² against Ha: σ₁² ≠ σ₂²

Confidence interval for the population mean difference is given by

(x`1- x`2) ± t √S²(1/n1 + 1/n2)

Where S ²= (n1-1)S₁² + S²₂(n2-1)/n1+n2-2

Critical value of t with n1+n2-2= 50+ 35-2= 83 will be -1.633

Now calculating

S ²=34* (12.8)²+ (14.6)²*49/83= 192.96

Now putting the values in the t- test

(75.1 -72.1) ± 1.633 √ 192.96(1/35 +1/50)

=3 ±  5.09

=-2.09, 8.09  is the 90 % confidence interval for the difference

The 90 % confidence limits are (-2.09, 8.09).

Since the calculated values do not lie in the critical region we accept our null hypothesis.

Please help! Will give Brainliest!
kkurt [141]

Answer:

  1. g(x) = 2|x|
  2. g(x) = -2|x|
  3. g(x) = -2|x| -3
  4. g(x) = -2|x-1| -3

Step-by-step explanation:

1) Vertical stretch is accomplished by multiplying the function value by the stretch factor. When |x| is stretched by a factor of 2, the stretched function is ...

  g(x) = 2|x|

__

2) Reflection over the x-axis means each y-value is replaced by its opposite. This is accomplished by multiplying the function value by -1.

  g(x) = -2|x|

__

3) As you know from when you plot a point on a graph, shifting it down 3 units subtracts 3 from the y-value.

  g(x) = -2|x| -3

__

4) A right-shift by k units means the argument of the function is replaced by x-k. We want a right shift of 1 unit, so ...

  g(x) = -2|x -1| -3

In the diagram, the measurements that are labeled are known, while the other measurements are unknown. Which measurement of acut
andrew-mc [135]
As the sine rule states,

A/sina = B/sinb = C/sinc .

in the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.

there are:

side a, with angle â .
side b, with angle b.

so the answer is C.

if you input these into the sine rule, it would be:

a/ sin a = b/sin b
