Answer:

1 + 5(77 - s) = 31

Step-by-step explanation:

Solve for s:

$-s+77=6\qquad\text{subtract 77 from both sides}\\\\-s=-71\qquad\text{change the signs}\\\\s=71$

Put the value of s to the expression 1 + 5(77 -s):

$1+5(77-71)$

Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

$=1+5(6)=1+30=31$

Answer:

$\boxed{\bold{31}}$

Explanation:

Solve $\bold{6= -s + 77}$

--------------------------

Add 's' To Both Sides

= $\bold{6+s=-s+77+s}$

Simplify

= $\bold{6+s=77}$

Subtract 6 From Both Sides

= $\bold{6+s-6=77-6}$

Simplify

= $\bold{s \ = \ 71}$

Insert '71' Into 1 + 5 (77 - s)

-------------------------------

1 + 5 (77 - 71)

Solve:

77 - 71 = 6

= 1 + 5 · 6

5 · 6 = 30

= 1 + 30

= 31

In Which Quadrant is this true

34kurt

Given:

$\sin \theta$

$\tan \theta$

To find:

The quadrant in which $\theta$ lie.

Solution:

Quadrant concept:

In Quadrant I, all trigonometric ratios are positive.

In Quadrant II, only $\sin\theta$ and $\csc\theta$ are positive.

In Quadrant III, only $\tan\theta$ and $\cot\theta$ are positive.

In Quadrant IV, only $\cos\theta$ and $\sec\theta$ are positive.

We have,

$\sin \theta$

$\tan \theta$

Here, $\sin\theta$ is negative and $\tan\theta$ is also negative. It is possible, if $\theta$ lies in the Quadrant IV.

Therefore, the correct option is D.

Solve for m. 5m+7/2 = −2m+5/2 a. -1/7 b. 6/7 c. 7 d. -1

Ainat [17]

$5m+\dfrac{7}{2}=-2m+\dfrac{5}{2}\qquad|\text{add 2m to both sides}\\\\7m+\dfrac{7}{2}=\dfrac{5}{2}\qquad|\text{subtract}\ \dfrac{7}{2}\ \text{from both sides}\\\\7m=\dfrac{5-7}{2}\\\\7m=\dfrac{-2}{2}\\\\7m=-1\qquad|\text{divide both sides by 7}\\\\\boxed{m=-\dfrac{1}{7}}$

Each day a commuter takes a bus to work, the transportation system has a phone app that tells her what time the bus will arrive.

Paraphin [41]

Answer:

Step-by-step explanation:

Hello!

The commuter is interested in testing if the arrival time showed in the phone app is the same, or similar to the arrival time in real life.

For this, she piked 24 random times for 6 weeks and measured the difference between the actual arrival time and the app estimated time.

The established variable has a normal distribution with a standard deviation of σ= 2 min.

From the taken sample an average time difference of X[bar]= 0.77 was obtained.

If the app is correct, the true mean should be around cero, symbolically: μ=0

a. The hypotheses are:

H₀:μ=0

H₁:μ≠0

b. This test is a one-sample test for the population mean. To be able to do it you need the study variable to be at least normal. It is informed in the test that the population is normal, so the variable "difference between actual arrival time and estimated arrival time" has a normal distribution and the population variance is known, so you can conduct the test using the standard normal distribution.

$Z_{H_0}= \frac{X[bar]-Mu}{\frac{Sigma}{\sqrt{n} } }$
