How to graph the equation y= 2x + 3 and y= 2x -2?
Komok [63]
Both equations are lines with a slope of 2. They will be parallel. They differ only in their y-intercept.

It can work well to graph the y-intercept, then plot another point that is at some horizontal distance from the y-axis and twice that distance above the y-intercept.

y = 2x + 3
Plot the point (0, 3) and the point (2, 7). Draw a line through those points.

y = 2x - 2
Plot the point (0, -2) and the point (2, 2). Draw a line through those points.

If length and width of a rectangle are in the ratio 4 to 5 and the perimeter of the rectangle is 144, find the dimensions of the
Zinaida [17]

Answer:

So dimension of rectangle are :

Length =  32

Width =  40

Step-by-step explanation:

Let the length of rectangle be 4x and width of rectangle be 5x.

Remember ratio of length and width is 4 to 5.

Perimeter of rectangle is given as 144.

i.e 2 (length +width) = 144

or 2 ( 4x + 5x ) = 144

Solving this for x, we get :

or 9x = 144/2

or 9x = 72

or x = 72/9

or x = 8

So dimension of rectangle are :

Length = 4 x = 4*8 = 32

Width = 5x = 5*8 = 40

In a large population, about 10% of people do not like the taste of cilantro, an herb used in cooking. A researcher takes a rand
bogdanovich [222]

Answer:

0.0019390

Step-by-step explanation:

10% of people do not like the taste of cilantro

A researcher takes a random sample of 15 people and surveys whether they like cilantro

Use the binomial distribution to compute the probability that exactly 6 of the people in the sample do not like cilantro.

Probability of success = 0.10 = p

Probability of failure = 0.9 =q

n = 15

r = 6

Formula : P(X=r)=^nC_rp^r q^{n-r}

P(X=6)=^{15}C_6 (0.1)^6 (0.9)^{15-6}

P(X=6)=\frac{15!}{6!(15-6)!} (0.1)^6 (0.9)^{15-6}

P(X=6)=0.0019390

Hence  the probability that exactly 6 of the people in the sample do not like cilantro is 0.0019390
