Answer:

4th Option is correct that is Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 1, 1, and 4. The graph intersects the y axis at a point between 0 and 5.

Step-by-step explanation:

Given polynomial function, f(x) = x^3 - 4x^2 - x + 4

We need to find graph which represent the polynomial function.

First we find y intercept by putting x = 0 in polynomial function.

y = f(0)

y=0^3-4(0)^2-0+4

y = 4

So, According to this information we only have Option 4th.

Now to check other information of option 4th we draw the polynomial on graph.

graph is attached.

from graph, x intercepts are -1 , 1 , 4

Therefore, 4th Option is correct that is Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 1, 1, and 4. The graph intersects the y axis at a point between 0 and 5.

Evaluate 13 - 0.75w+8x when w=12 and x= 1 over 2
Zepler [3.9K]

Answer:

8

Step-by-step explanation:

Given:

13 - 0.75w + 8x

where,

w = 12

x = 1/2

13 - 0.75w + 8x

Substitute the value of w and x into the equation

= 13 - 0.75(12) + 8(1/2)

= 13 - 9 + 8/2

= 13 - 9 + 4

= 8

Therefore,

13 - 0.75w + 8x = 8

All exponential functions can be written in many forms. Write the function f(t)=110(1.35)^{\frac{t}{40}}f(t)=110(1.35) 40 t ​ in
Mkey [24]

Step-by-step explanation:

Given - f(t)=110(1.35)^{\frac{t}{40}}

To find - Write the function in the form f(t)=ae^{kt}. Round all coefficients

               to four decimal places.

Proof -

Given that , the function is  f(t)=110(1.35)^{\frac{t}{40}}

Now,

We can write it in the form of  f(t) = 110(1.35)^{\frac{t}{40} }

By comparing with the form  f(t) = ae^{kt} , we get

a = 110.0000

k = \frac{1}{40} = 0.0250

A random sample of 500 people is taken. 260 of them rent (as oppose to own) their residence. Compute a 95% confidence interval f
kirill [66]

Answer: A 95% confidence interval for the true proportion (p) will be (0.4762136, 0.5637864).

Step-by-step explanation:

Let p = True proportion of people rent their residence.

Given: n= 500

People rent their residence = 260

p=\dfrac{260}{500}=0.52

z-value for 95% confidence level = 1.96

A 95% confidence interval for the true proportion will be :

p\pm z^*\sqrt{\dfrac{p(1-p)}{n}}

0.52\pm (1.96)\sqrt{\dfrac{0.52(1-0.52)}{500}}\\\\=0.52\pm(1.96\sqrt{\dfrac{0.2496}{500}})\\\\=0.52\pm 1.96\sqrt{0.0004992}\\\\=0.52\pm (1.96)(0.02234)\\\\=0.52\pm0.0437864\\\\=(0.52-0.0437864,\ 0.52+0.0437864)\\\\=(0.4762136,\ 0.5637864)

A 95% confidence interval for the true proportion (p) will be (0.4762136, 0.5637864).
