There is A Spinner That Have 8 Space 1-8 What Is The Probability That Te Spinner Will NOT Land On 5 or 8?

insens350 [35]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Key skills needed: Probability, Possible Outcomes

1) We are given a spinner --> With numbers: 1,2,3,4,5,6,7, and 8

That means there are 8 numbers on the spinner.

2) The problem asks what is the probability that the spinner will not land on 5 or the 8.

To calculate this --> $\frac{acceptedoutcomes}{total}$

3) The accepted outcomes are when the spinner lands on --> 1,2,3,4,6,7

That is 6 accepted outcomes.

4) The total outcomes is 8 (since there are numbers the spinner can land on).

5) Therefore, the answer would be $\frac{6}{8}$

$\frac{6}{8}$ can be simplified into $\frac{3}{4}$ as both the numerator (6) and the denominator (8) share a factor of 2.

6) With this --> $\frac{3}{4}$ is the answer.

A line passes through the point(-4,-6) and has a slope of 1/2 What is the equation of the line?

alex41 [277]

Answer:

x-2y-8=0

Step-by-step explanation:

The equation of line is given by the relation

y-y1=m(x-x1)

where m is the slope

now, given x1=-4 and y1=-6 and the slope is 1/2.

substitute into the equation to get

y+6=1/2(x+4)

multiplying through with the L.C.M

which is 2

2(y+6)=1/2×2(x+4)

2y+12=x+4

making x the subject

x= 2y+8 hence the equation of the line is x-2y-8 =0

Mathematical symbols are critical to the discipline of statistics. A symbol can help identify which distribution and what type o

Shtirlitz [24]

Answer: sigma is used for measuring Population Standard Deviation.

Step-by-step explanation:

The lower case Greek letter 'sigma' is denoted by the symbol ( $\sigma$ ).

This symbol indicates the Population Standard Deviation of the data. Standard deviation means how much variation or dispersion is there in our data. Squaring of standard deviation gives us Variance which is denoted by the symbol $\sigma ^{2}$ .

Formula for Population Standard deviation ( $\sigma$ ) is = $\sqrt{\frac{\sum (x_i-\mu )^{2}}{N}}$ ,

where $x_i$ = each value from our list of data

$\mu$ = Population mean of data

N = Number of observations in our data

Standard deviation can never be negative and it is very much sensitive to outliers in our data.
