Answer:

y = 1/2 x + 3

Step-by-step explanation:

Slope = (4 - 1) / (2 + 4) = 3/6 = 1/2

Equation

y - 4 = 1/2(x - 2)

y - 4 = 1/2 x - 1

y = 1/2 x + 3

Find the slope of the line passing through each of the following pairs of points and draw the graph of the line. (5, 2), (3, 3)

Strike441 [17]

Answer:

-0.5

Step-by-step explanation:

slope=rise/run or y/x in other words(y2-y1/x2-x1)
(y2-y1) is 3-2 so y2-y1=1
(x2-x1) is 3-5 so x2-x1= -2
-1/2 or -0.5 would be the slope.

In a recent survey 75 of the community favored building a police substation in their neighborlhood. If 20 citizens are chosen. W

Anton [14]

Answer:

Mean = 15

Standard deviation = 1.94

Step-by-step explanation:

We are given the following information:

We treat favoring of building a police substation as a success.

P(Success) = 75% = 0.75

Then the number of citizens follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 20

We have to find the mean and the standard deviation.

$\mu = np = 20(0.75 ) = 15\\\sigma = \sqrt{np(1-p)} = \sqrt{20(0.75)(1-0.75)} = 1.94$

Thus, the mean of favoring the substation is 15 and the standard deviation of favoring substation is 1.94

The combination for a lock is a 3-digit number. The digits are the prime factors of 42 listed from least to greatest. What is th

Dvinal [7]

Answer:

2, 3, 7

Step-by-step explanation:

Since you know your multiplication tables, you know that ...

42 = 6 × 7

and

6 = 2 × 3

The numbers 2, 3, and 7 are prime numbers (not further divisible). This list is in order least to greatest, so is the combination of the lock.
