The answer is d.
to find the slope you can do y2-y1/x2-x1
8-(-1)/3-0= 9/3 or 3
you can then put one of the points into the slope intercept form y=mx+b or 8=3(3)+b
you get 8=9+b. you subtract 9 from both sides to get -1=b. y intercept means that the point is (0,-1)

The length of a rectangular field is 7 m less than 4 times the width. The perimeter is 136 m. Find the width and the length

Helga [31]

Answer:

Step-by-step explanation:

Represent the width by W. Then, "The length of a rectangular field is 7 m less than 4 times the width" expressed symbolically is

L = 4W - 7 (dimensions in meters)

Recall that the perimeter formula in this case is P = 2L + 2W, and recognize that the perimeter value is 136 m. After substituting 4W - 7 for L, we get:

136 m = 2(4W - 7) + 2W, or

136 = 8W - 14 + 2W, or

150 = 10W These three equations are equivalent mathematical statements.

150 = 10W reduces to W = 15 (meters).

Part A: the independent variable is W, the width of the field.

Part B: The mathematical statement is 136 m = 2(4W - 7) + 2W, which after algebraic manipulation becomes 150 = 10W.

Part C: The above equation can be solved for W: W = 15 meters. This is the value of the independent variable.

Given the function f(x)=x^2 and I= -3, which of the following represents a vertical shift

Anika [276]

Answer:

See below.

Step-by-step explanation:

You haven't supplied a list but one option could be f(x) - l or x^2 - l.

This represents a vertical shift of 3 units downwards.

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
