Answer:

The axis of symmetry should be x = 2.

Step-by-step explanation:

:)

We have given that the function y = - (x + 2)² - 1. So, The axis of symmetry should be x=2 describing the error in the graph.

If a quadratic equation is written in the form

[tex]y=a(x-h)^2 + k[/tex]

then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)

This point (h,k) is called the vertex of the parabola that the quadratic equation represents.

We have given that the function y = - (x + 2)² - 1

so we have a =-1,

-h=2 implies that h=-2

k=-1

Therefore the vertex is (h,k)=(-2,-1)

vertex = (- 2, - 1)  

The axis of symmetry passes through the vertex, is vertical with the equation

x = - 2 is correct.

When the a > 0, the vertex is a minimum

when  a < 0, implies that vertex is a maximum

here a=-1 < 0 implies vertex should be a maximum

Since, the vertex(-2,-1) is maximum

Therefore the axis of symmetry should be x=2 to represent error in the graph.

Answer:

sin∅=3/4

Step-by-step explanation:

sin²x+cos²x=1

sin²x+(√7/4)²=1

sin²x+7/16=1

sin²x=9/16

sinx=3/4

Therefore, sin∅=3/4

Answer:

0.12 ± 1.96 * √(0.12(0.88) / 100)

Step-by-step explanation:

Confidence interval :

Phat ± Zcritical * √(phat(1 -phat) / n)

Phat = 12/100 = 0.12

1 - phat = 0.88

Zcritical at 95% = 1.96

Hence, we have :

0.12 ± 1.96 * √(0.12(0.88) / 100)

0.12 ± 1.96 * 0.0324961

0.12 ± 0.0636924

Lower boundary = (0.12 - 0.0636924) = 0.0563

Upper boundary = 0.12 + 0.0636924 = 0.1837

The calculations for 95% confidence interval for this case is given as: [tex]CI = 0.12 \pm 1.96 \times \sqrt{\dfrac{0.12(1 - 0.12)}{100}}[/tex]

For large enough sample( size > 30), let the population proportion of a quantity be denoted by random variable [tex]p[/tex]

Then, we get:

[tex]p \sim N(\hat{p}, \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}})[/tex]

where

[tex]\hat{p}[/tex] = estimated(mean value) proportion of that quantity

and n = size of sample drawn.

It is visible that as we increase the value of n, the standard deviation decreases, therefore, forcing the values of population proportion to be closer to the estimated proportion.

Margin of error is the distance between the mean and one of the end point of the confidence interval(assuming its equal on  both the sides of the mean). The margin of error with level of significance [tex]\alpha[/tex] is calculated as:

[tex]MOE = Z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

where [tex]Z_{\alpha/2}[/tex] is the critical value of the test statistic for level of significance [tex]\alpha[/tex]

The confidence interval is then calculated as:

[tex]CI = \hat{p} \pm MOE[/tex]

For the considered case,

the confidence interval is to be found for 95% confidence, therefore,

level of significance = 100% - 95%  = 5% = 0.05

The estimated proportion of defective chips estimated from sample is:

Thus, we get the confidence interval for this case as:

[tex]CI = \hat{p} \pm Z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\CI = 0.12 \pm 1.96 \times \sqrt{\dfrac{0.12(1 - 0.12)}{100}}[/tex]

Thus, the calculations for 95% confidence interval for this case is given as: [tex]CI = 0.12 \pm 1.96 \times \sqrt{\dfrac{0.12(1 - 0.12)}{100}}[/tex]

Step-by-step explanation:

A: 1 Ruler for $0.25

B: $0.30

C: $0.20

D: $0.15

It is 75%.

Hope this helps.

We can write the complete statement as -

75% of 80 is equivalent to 60.

We can represent "a% of b" as -

a% of b = a/100 x b

a% of b = ab/100

So, a% of b = ab/100

Given is to find what percent of 80 is 60​.

Assume that {x}% of 80 is equivalent to 60. So, we can write -

60 = x% of 80

60 = {x}/100 x 80

60 = 80x/100

60 = 8x/10

x = 600/8

x = 75

So, we can write that

75% of 80 is equivalent to 60.

Therefore, we can write the complete statement as -

75% of 80 is equivalent to 60.

Answer:

A)  The probability that a randomly chosen car is made in Germany or Japan is 40%.

B)  The probability that a car chosen at random is not made in the United States is 60%.

C)  The probability that two randomly chosen cars are both from Japan is 9%.

Step-by-step explanation:

Supposing that 40% of cars in my area are manufactured in the US, 30% in Japan, 10% in Germany, and 20% in other countries, to determine the probabilities that a car selected at random is made in Germany or Japan, a car selected at random is not US-made and two cars are selected at random, both are from Japan, the following calculations must be performed:

A)

(30 + 10) / 100 = X

40/100 = X

0.4 = X

Therefore, the probability that a randomly chosen car is made in Germany or Japan is 40%.

B)

(30 + 10 + 20) / 100 = X

60/100 = X

0.6 = X

Therefore, the probability that a car chosen at random is not made in the United States is 60%.

C)

10/30 x 10/30 = X

0.3 x 0.3 = X

0.09 = X

Therefore, the probability that two randomly chosen cars are both from Japan is 9%.

Answer:

TR = 3 units

Step-by-step explanation:

PR = 12 units

PS = 9 units

PU = PS = 9 units (tangents drawn from an external point are congruent)

RU = PR - PU

RU = 12 - 9

RU = 3 units

TR = RU = 3 units (tangents drawn form an external point of a circle)

TR = 3 units

Answer:

y = 2(x - 2)² + 3      vertex form

y = 2x² - 8x + 11     standard form

Step-by-step explanation:

Vertex form

y = a(x - h)² + k

(h, k) = (2, 3)

y = a(x - 2)² + 3

To find "a" plug in the y-intercept (0, 11)

11 = a(-2)² + 3

11 = 4a + 3

Subtract 3 from both sides

8 = 4a

a = 2

y = 2(x - 2)² + 3

Expand

y = 2(x² - 4x + 4) + 3

y = 2x² - 8x + 11

Answer:

11.55 years

Step-by-step explanation:

Given data

Principal= $3000

Rate= 6%

Final Amount= $6000

expression for the time is given as

t = ln(A/P) / r

Substitute

t= ln(6000/3000)/0.06

t= ln(2)/0.06

t= 0.693/0.06

t= 11.55 years

Hence the time is 11.55 years

x-4/4=x/6+1

x-4 =4/6x+4

x-2/3x =8

1/3x =8

x=24

Answer and Step-by-step explanation:

The first step in solving for x is to square both sides.

8x = 4 + 2x

Now, subtract 2x from both sides.

6x = 4

Now, divide each side by 6.
