What is the slope of the line that passes through the points (-8, -6)(−8,−6) and (-18, 6) ?(−18,6)? Write your answer in simplest form.

Answer:

x=6

Step-by-step explanation:

30=6+4x

you have to combine the number that are the same, like 2 and 4 or 3x and 4x

30-6=4x (you should always remember when you move a number if it was - it will turn +)

30-6=4x

24=4x

x=24/4

x=6

Answer:

Step-by-step explanation:

The z-score of an appliance that stopped working at 64 months is 2

Standard score or z score in statistics is defined as the number of standard deviations by which that the value of a score is above or below the mean value.

The formula to find the z score of a data is,

z = (x - μ) / σ

Here x is the observed value, μ is the mean and σ is the standard deviation.

Given that,

Mean = 48 months

Standard deviation = 8 months

x = 64 months

Substituting in the formula,

z = (64 - 48) / 8 = 2

Hence the z score of the appliance is 2.

Answer:

The mean of Trail Middle School wrestling team is greater by 20 pounds as compared to that of Burlington Middle School  wrestling team

Step-by-step explanation:

Since the value of absolute deviation in case of Trail Middle School wrestling team and Burlington Middle School  wrestling team is same. Hence, there will be no impact of it while determining the difference in mean deviation of both the team.

Thus, the difference in mean deviation is [tex]150-130 = 20[/tex]

The mean of Trail Middle School wrestling team is greater by 20 pounds as compared to that of Burlington Middle School  wrestling team

Step-by-step explanation:

Given that the mean value of the distribution is 1.1, then we can safely assume that the peak value will be reside around one with a variability measure, standard (1.5) represents changes in distribution away from the mean value. The could be to either side of the distribution. However, the cannot be a negative value for the number of courses taken, hence, the maximum value we can have to the left is 0. (figures to the far left of the distribution are negative). This means that the curve will fall towards the right, (positive direction hence giving a right skewed distribution.

Step-by-step explanation:

To solve the problem [tex]-\frac{3}{4} (-8a-12)[/tex]

we first use the distributive property, which means to multiply everything on the inside with the outside number on the left.

so [tex]-\frac{3}{4} * -8a, -\frac{3}{4} *-12[/tex]

This would equal

[tex]6a+9[/tex]

its pretty simple.

what may be confusing is the fraciton multiplication

to solve this we convert the -8 and -12 into a fraction. This would be

[tex]-\frac{8}{1} and-\frac{12}{1}[/tex]

and multiplying fractions is easy, u just do it straight across.

so 3 times 8 is 24 so this would be 24/4

and 24/4 simplified is 6

and 3 times 12 is 36

so it would be 36/4

this would equal 9 simplified

and since we are just multiplying all negative numbers here they all turn out to be positive numbers because you should know.  a negative times a negative equals a positive.
