In the ordered pair below, which value represents the output of a function? (1, 9) ?

A newsletter publisher believes that less than 58% of their readers own a Rolls Royce. For marketing purposes, a potential adver

Answer:

We don´t have at 95% of confidence, evidence to reject the publisher´s claim

Step-by-step explanation:

Population mean p₀ = 58 % or p₀ = 0,58

Hypothesis Test:

Null Hypothesis H₀ p = p₀

Alternative Hypothesis Hₐ p < p₀

For a significance level α = 0,05 means that CI = 95 % or CI = 0,95

z(c) = - 1,64

MOE = z(c)* √(p*q)/n

p - p₀ / √(p*q)/n = z(s)

And that z(s) is in the acceptance region

|z(s)| < |z(c)|

|z(s)| < 1,64

Then if that so we fail to reject H₀ . We don´t have evidence to reject the publisher´s claim

Answer: velocity-time graph

Step-by-step explanation: The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

Find the smallest zero solution of h(x)= 4x^2-8x-60

Komok [63]

-3.

Multiply 60 with 4 and then find the factor when added together which would give you the middle number. Notice that because it is a negative equation that both signs are negative. This means that the biggest factor of 240 will be negative.

Then, rewrite the equation 4x^2 +12x -20x -60 and divide it into two parts (4x^2 + 12x) (-20x-60) and then factor each part. If done correctly, the numbers left in the parenthesis should be the same. This way the part outside is one factor and the part inside is the other. This should get you 4x -20 and x +3.

Set both equal to zero and you get your two solutions. One is -3 and the other is 5.

Hope this helps!

In the diagram given below, lines I1 and l2 are parallel and t is a transversal. Find the value of x.

Hey!!!

Solution,

2x+10+X+5=180 ( sum of co-interior angles)

or, 2x+X+10+5=180

or,3x+15=180

or,3x=180-15

or,3x=165

or, X=165/3

X=55

<h3>So the value of X is 55.</h3>

Hope it helps...

Good luck on your assignment
