What should be done to both sides of the equation in order to solve -5m=-40

Answers

Answer 1

Answer:

Answer:

divide each side by -5

Step-by-step explanation:

-5m = -40

divide each side by -5

-5m/-5 = -40/-5

m = 5

Answer 2

Answer:

Hello, there!

Answer:

m=8 or 8=m

*The answer must have a positive sign.*

Step-by-step explanation:

First, you had to divide by -5 from both sides of an equation.

$(-5m)/(-5)=(-40)/(-5)$

And, then simplify and solve equation.

$40/5=8$

$m=8$

Hope this helps!

In a study of plant safety, it was found that the time it took for machine operators to react to a warning light was normally distributed with a mean 1 second and standard deviation 0.3 second. Suppose a warning light visible to 4 operators goes on. What is the probability that the average (mean) reaction time of the 4 operators exceeds 1.25 seconds?

Answers

Answer:

4.75% probability that the average (mean) reaction time of the 4 operators exceeds 1.25 seconds.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $(\sigma)/(√(n))$

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = (X - \mu)/(\sigma)$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 1, \sigma = 0.3, n = 4, s = (0.3)/(√(4)) = 0.15$

What is the probability that the average (mean) reaction time of the 4 operators exceeds 1.25 seconds?

This is 1 subtracted by the pvalue of Z when X = 1.25. So

$Z = (X - \mu)/(s)$

$Z = (1.25 - 1)/(0.15)$

$Z = 1.67$

$Z = 1.67$ has a pvalue of 0.9525.

So there is a 1-0.9525 = 0.0475 = 4.75% probability that the average (mean) reaction time of the 4 operators exceeds 1.25 seconds.

In the given question some information is missing that is attachment of file which can be described as follows:

Add products:

$\rightarrow \ ((1)/(8))* 1+((1)/(4))* 1+((1)/(2))* 3+((3)/(4))*8+(1)*4+1 (3)/(8)* (2)1 (3)/(8) \n\n \rightarrow 11/8\n\n$

$\rightarrow (1)/(8)* 1+((1)/(4))*1+((1)/(2))*3+((3)/(4))*8+(1)*4+(11)/(8)*(2)\n\n$

$\rightarrow ((1)/(8))+((1)/(4))+((3)/(2))+(6)+(4)+(11)/(4)\n\n\rightarrow ((1+2+12+48+32+22)/(8)) \n\n\rightarrow (117)/(8) \n\n \rightarrow 14.625 \ ft \n$

Can someone help me with this math problem 26.04 divided by -6.2

Answers

Answer:

-4.2

Step-by-step explanation:

To divide 26.04 by -6.2, you can follow these steps: Multiply both numbers by 10 to eliminate decimal places. Divide the resulting numbers. The answer is 4.24.

To divide 26.04 by -6.2, you can follow these steps:

Multiply both the dividend and divisor by 10 to eliminate the decimal places. You will get -262.4 divided by -62.
Divide the numbers as usual. -262.4 divided by -62 equals 4.24.

Therefore, 26.04 divided by -6.2 is equal to 4.24.

QuestionGiven that tan(0) =5/12
and 0 is in Quadrant III. what is cos(0)? Write your answer in exact form. Do not round.
Provide your answer below:

Answers

Answer:

cosΘ = - $(12)/(13)$

Step-by-step explanation:

Given that Θ is in the third quadrant then cosΘ < 0

Given

tanΘ = $(5)/(12)$ = $(opposite)/(adjacent)$

Then 5 and 12 are the legs of a right triangle (5- 12- 13 ) with hypotenuse = 13

Thus

cosΘ = - $(adjacent)/(hypotenuse)$ = - $(12)/(13)$
