top left choice

Step-by-step explanation:

the slope is negative, so its flipped

the y int is -6, below the x axis

Answer:

Graph A (the top left)

Step-by-step explanation:

The correct graph has to have a negative slope. So this narrows the options down to either A (top left) or B (top right). The y-intercept has to be negative, and out of A and B, only Graph A meets this requirement.

From the unit circle, we can locate the two values of sine Ф (y-value of the coordinate)  at which sin Ф = √3/2.

The two values are Ф = π/3 and 2π/3.

Answer:

C

Step-by-step explanation:

so the first one ends at 4.7107

the second- 3.3568

the third- 5.1401

and multiplying the first by 5000 we get- 23,553.5

for the second we get -6,713.6

for the third we get 41,120

adding them all together we get 71,387.1

and so C is the closest

The  value of the index at the end of the day should be considered as the $70,400.

Since

Stock X opens the day with 5000 shares at $4.30 per share.

Stock Y opens the day with 2000 shares at $3.20 per share.

Stock Z opens the day with 8000 shares at $4.90 per share.

This simple index rises 4.9% over the course of the day.  

So ,

[tex]= (5,000 \times \$3.4) + (2,000 \times \$3.20) + (8,000 \times $4.90) * 1.0.49[/tex]

= $70,400

hence, The  value of the index at the end of the day should be considered as the $70,400.

Answer:

Step-by-step explanation:

Given that:

the sample proportion p = 0.39

sample size = 100

Then np = 39

Using normal approximation

The sampling distribution from the sample proportion is approximately normal.

Thus, mean [tex]\mu _{\hat p} = p = 0.39[/tex]

The standard deviation;

[tex]\sigma = \sqrt{\dfrac{p(1-p)}{n} }[/tex]

[tex]\sigma = \sqrt{\dfrac{0.39(1-0.39)}{100} }[/tex]

[tex]\sigma = 0.048[/tex]

The test statistics can be computed as:

[tex]Z = \dfrac{{\hat _{p}} - \mu_{_ {\hat p}} }{\sigma_{\hat p}}[/tex]

[tex]Z = \dfrac{0.3 - 0.39 }{0.0488}[/tex]

[tex]Z = -1. 8 4[/tex]

From the z - tables;

[tex]P (\hat p \le 0.3 ) = P(z \le -1.84)[/tex]

[tex]\mathbf{P (\hat p \le 0.3 ) = 0.0329}[/tex]

(b)

Here;

the sample proportion = 0.39

the sample size n = 400

Since np = 400 * 0.39 = 156

Thus, using normal approximation.

From the sample proportion, the sampling distribution is approximate to the mean [tex]\mu_{\hat p} = p = 0.39[/tex]

the standard deviation [tex]\sigma_{\hat p} = \sqrt{\dfrac{p(1-p)}{n} }[/tex]

[tex]\sigma_{\hat p} = \sqrt{\dfrac{0.39 (1-0.39)}{400} }[/tex]

[tex]\sigma_{\hat p} =0.0244[/tex]

The test statistics can be computed as:

[tex]Z = \dfrac{{\hat _{p}} - \mu_{_ {\hat p}} }{\sigma_{\hat p}}[/tex]

[tex]Z = \dfrac{0.3 - 0.39 }{0.0244}[/tex]

[tex]Z = -3.69[/tex]

From the z - tables;

[tex]P (\hat p \le 0.3 ) = P(z \le -3.69)[/tex]

[tex]\mathbf{P (\hat p \le 0.3 ) = 0.0001}[/tex]

(c) The effect of the sample size on the sampling distribution is that:

As sample size builds up, the standard deviation of the sampling distribution decreases.

In addition to that, reduction in the standard deviation resulted in increases in the Z score, and the probability of having a sample proportion  that is less than 30% also decreases.

Step-by-step explanation:

Based on the information given regarding the function, the correct option is C. g (x) = negative StartRoot x + 3 EndRoot + 8.

It should be noted that a function simply means the relation from a set of inputs to a set of possible outputs.

In this case, the function that has the same range as | f (x) = negative 2 StartRoot x minus 3 EndRoot + 8 will be g (x) = negative StartRoot x + 3 EndRoot + 8.

Answer:

w=64

Step-by-step explanation:

you just have to multiply 4 on both sides to cancel the 1/4, and 16x4=64

Answer:

Step-by-step explanation:

We will undo the operations that obscure the value of W to find its value.

1/4W = 16

Since we divided W by 4 (1/4W is the same a W/4), we will multiply both sides by 4.

16 x 4 = 64.

The value of W is 64.

#The 75% of 3/4?

#Just times it.

75/100 × 3/4 = 225/400 =9/16

#so, the 75% of 3/4 is 9/16

The equivalent value of the percentage is A = 9/16 = 0.5625 = 56.25 %

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be represented as p

Let the percentage be represented as q

Now , A = pq

when the value of p = 3/4

And , when the value of q =75 %

On simplifying the equation , we get

A = ( 75 % ) ( 3/4 )

So , the left hand side of the equation is equated to the right hand side by the value of ( 75 % ) ( 3/4 )

Now , the value of 75 percentage = 3/4

A = ( 3/4 ) ( 3/4 )

A = 9/16

On simplifying , we get

Multiply by 3 on the fraction , we get

A = 0.5625

Therefore , the value of A = 9/16

Hence , the fraction is A = 9/16
