Complete Question

Determine whether the normal sampling distribution can be used. The claim is p < 0.015 and the sample size is n=150

Answer:

Normal sampling distribution can not be used

Step-by-step explanation:

From the question we are told that

The null hypothesis is $H_o : p = 0.015$

The alternative hypothesis is $H_a : p < 0.015$

The sample size is n= 150

Generally in order to use normal sampling distribution

The value $np \ge 5$

$np = 0.015 * 150$

$np = 2.25$

Given that $np < 5$ normal sampling distribution can not be used

What is the measurement of angle 1 plz help me !

Evgen [1.6K]

Answer:

ANGLE 1 = 40°

Step-by-step explanation:

angle 1 = angle 2 ------(alternate interior angles)

2x + 20 = 3x + 10

20 - 10 = 3x - 2x

x = 10.

Angle 1 = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°.

Which polynomial function can be represented by the graph below

s344n2d4d5 [400]

<u>Answer:</u>

The correct answer option is C. $f(x)=-2x^3-2x^2+12x$ .

<u>Step-by-step explanation:</u>

From the given graph of the polynomial function, we can see that the graph passes through the following points: $(-3,0), (0,0)$ and $(2,0)$ .

So the roots or zeros of this polynomial function are: $-3,0$ and $2$ .

Now, we'd graph the equation of the given polynomial and will check for roots and end behavior of the graph.

Therefore, the polynomial function that is represented by the graph is:

$f(x)=-2x^3-2x^2+12x$
