You travel between these two mile markers and then find your average speed in miles per hour. Which equation does NOT represent

Jet001 [13]

Answer:

The correct option is C.

Step-by-step explanation:

The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.

So total time taken by car is

$4:30-3:00=1:30$

It means total time taken by car is 1.5 hour.

The distance in first figure is 50 miles and the speed in second figure is 155 miles.

So total distance travelled by car is

$155-50=105$

It means total distance travelled by car is 105 miles.

The formula of speed is

$Speed=\frac{Distance}{Time}$

$Speed=\frac{105\text { miles }}{1.5\text{ hours}}$

Therefore option B represents the solution. Option B is incorrect.

Multiply both sides by 1.5 hours.

$1.5\text{ hours}\times Speed=105\text { miles }$

Therefore option D represents the solution. Option D is incorrect.

Divide both sides by speed.

$1.5\text{ hours}=\frac{105\text { miles }}{Speed}$

Therefore option A represents the solution. Option A is incorrect.

Option C can not represent the solution, therefore option C is correct.

The horizontal viewing angle is the angle subtended by a straight line from

SSSSS [86.1K]

The measure of the arc is given as π/2. See the explanation below.

An "arc" is a curve that connects two points in mathematics.

It can also be depicted as a section of a circle. It is essentially a portion of a circle's circumference. An arc is a kind of curve.

<h3>What is the calculation for the above solution?</h3>

Note that the viewing angle is 45°.

Thus, the center angle is:
45 X 2 = 90°

Measure of the arc therefore is:
= (π/180°) x 90

= π/2

The proportion of students at a college who have GPA higher than 3.5 is 19%. a. You take repeated random samples of size 25 from

melomori [17]

Answer:

$\mu_{\hat{p}}=0.19$

$\sigma_{\hat{p}}=0.0785$

Step-by-step explanation:

We know that the mean and the standard error of the sampling distribution of the sample proportions will be :-

$\mu_{\hat{p}}=p$

$\sigma_{\hat{p}}=\sqrt{\dfrac{p(1-p)}{n}}$

, where p=population proportion and n= sample size.

Given : The proportion of students at a college who have GPA higher than 3.5 is 19%.

i.e. p= 19%=0.19

The for sample size n= 25

The mean and the standard error of the sampling distribution of the sample proportions will be :-

$\mu_{\hat{p}}=0.19$

$\sigma_{\hat{p}}=\sqrt{\dfrac{0.19(1-0.19)}{25}}\\\\=\sqrt{0.006156}=0.0784601809837\approx0.0785$

Hence , the mean and the standard error of the sampling distribution of the sample proportions :

$\mu_{\hat{p}}=0.19$

$\sigma_{\hat{p}}=0.0785$

Help!!! i don’t understand how i would be able to find rt

liq [111]

Given:

M is the mid-point of RS

N is the mid-point of ST

MN = 18.4

To find:

The length of RT.

Solution:

The reference image is attached below.

Joining mid-point M and N, we get mid-segment MN.

MN is parallel to RT.

Triangle mid-segment theorem:

If a segments joins the mid point of a two sides of triangle, then the segment is parallel to the third side and is half of that side.

$$\Rightarrow MN=\frac{1}{2} RT$

Substitute MN = 18.4

$$\Rightarrow 18.4 =\frac{1}{2} RT$

Multiply by 2 on both sides.

$$\Rightarrow 2\times 18.4 =2\times \frac{1}{2} RT$

$$\Rightarrow 36.8=RT$

The length of RT is 36.8.
