Answer:

The 95% confidence interval to estimate the true proportion of evens rolled on a die is (0.2842, 0.6758). This means that we are 95% sure that for the entire population of dies, the true proportion of evens rolled on a die is between 0.2842 and 0.6758

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

For this problem, we have that:

[tex]n = 25, \pi = \frac{12}{25} = 0.48[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.48 - 1.96\sqrt{\frac{0.48*0.52}{25}} = 0.2842[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.48 + 1.96\sqrt{\frac{0.48*0.52}{25}} = 0.6758[/tex]

The 95% confidence interval to estimate the true proportion of evens rolled on a die is (0.2842, 0.6758). This means that we are 95% sure that for the entire population of dies, the true proportion of evens rolled on a die is between 0.2842 and 0.6758

Answer:

4cm

Step-by-step explanation:

The volume of the cylinder is the product of the area of the base and the height. In mathematical equation, this can be written as,

                                     V = πr²h

where V is volume, r is the radius, and h is the height.

Substituting the known values from the given,

                                 176π cm³ = πr²(11 cm)

(x – 8)2 + (y – 10)2 = 36

Step-by-step explanation:I took the test

The equation of a circle with center at  [tex](8, 10)[/tex]  and radius [tex]6[/tex] will be  

[tex](x-8)^2+(y-10)^2=36[/tex]  which is given in option [tex](3)[/tex] .

Equation of a circle is written in the form [tex](x-h)^2+(y-k)^2=r^2[/tex] where  [tex](h,k)[/tex]  is the center and  [tex]r[/tex]  is the radius.

We have,

The center at  [tex](8, 10)[/tex]  and radius is [tex]6[/tex] .

i.e.

[tex]h=8[/tex]

[tex]k=10[/tex]

[tex]r=6[/tex]

So, using the above given equation,

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

Putting the above values in this equation

We get,

[tex](x-8)^2+(y-10)^2=(6)^2[/tex]

i.e.

[tex](x-8)^2+(y-10)^2=36[/tex]

This is the equation of a circle which is derived using the above given equation.

Hence, we can say that the equation of a circle with center at  [tex](8, 10)[/tex]  and radius [tex]6[/tex] will be [tex](x-8)^2+(y-10)^2=36[/tex]  which is given in option [tex](3)[/tex] .

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

According to the distance formula , for any 2 points P & Q whose coordinates are (x¹ , y¹) and (x² , y²) respectively. So ,

[tex]PQ = \sqrt{(x^{2} - x^{1} )^{2} + (y^{2} - y^{1})^{2} }[/tex]

NOTE = HERE x² , y² DOESN'T MEAN THE SQUARES OF x & y . THEY ARE JUST COORDINATES.

According to the question ,

Coordinate of C = (2 , -1)

Coordinate of D = (5 , 3)

Using distance formula ,

[tex]CD = \sqrt{(5-2)^{2} + (3 -(-1))^{2} }[/tex]

[tex]=> CD = \sqrt{3^{2} + 4^{2} } = \sqrt{9 + 16} = \sqrt{25} = 5[/tex]

Answer:

1.94 + 24x = 43.22 ;

1.72

Step-by-step explanation:

Given :

Cost of orange = 1.94

Pack of juice = 24

Total amount spent = 43.22

Cost of orange + (number of juice * cost per bottle) = total amount spent

Let cost per bottle = x

1.94 + (24 * x) = 43.22

1.94 + 24x = 43.22

24x = 43.22 - 1.94

24x = 41.28

x = 41. 28 / 24

x = 1.72

Answer:

The x- and y-coordinates are switched.

Step-by-step explanation:

Given that:

Point L plotted by Raj is in a coordinate plane.

Point L is 1.5 units to the left and is 4 units up.

As per Raj, the point is (4, -1.5).

Kindly refer to the general coordinate plane diagram in the answer area.

The origin is at (0,0) which is our reference point for plotting any point.

When we move left on the coordinate plane from origin, the [tex]x[/tex] coordinate will decrease i.e. will become negative.

When we move right on the coordinate plane from origin, the [tex]x[/tex] coordinate will increase i.e. will become positive.

When we move down on the coordinate plane from origin, the [tex]y[/tex] coordinate will decrease i.e. will become negative.

When we move up on the coordinate plane from origin, the [tex]y[/tex] coordinate will increase i.e. will become positive.

Now, as per question statement, 1.5 units to the left.

i.e. [tex]x[/tex] = -1.5

4 units up.

i.e. [tex]y[/tex] = 4

Therefore, the point will be (-1.5, 4).

So, the answer is:

The x- and y-coordinates are switched.

If you mean he starts at 1 on the Y axis (vertical line), then the answer is (1, 3). If you mean he starts at 1 on the X axis (horizontal line), then the answer is (0, 4)

Answer:

4 and 4 away

Step-by-step explanation:

If you start at one on the number line and go to the right you'll end up on 4 because if you start from one and then add 3 that equals 4.

Now if you were to figure out how FAR he is away from 0 you have to start at for and figure out what number you have to minus 4 by to get zero which is 4 because 4-4=0
